ABSTRACT

A Retículo Peritonite Traumática está diretamente ligada à ingestão de objetos metálicos perfuro cortantes, como pregos e pedaços de arame, que podem penetrar ou perfurar a parede do retículo. Embora a ocorrência de corpos estranhos de alumínio seja rara, outros elementos, como fios de pneus usados para fixar lonas em silagens e até cerdas de arame de escovas utilizadas em pequenos aeroportos, têm sido registrados como causas dessa afecção. A ingestão desses objetos pode resultar em lesões no retículo, desencadeando episódios de retículo peritonite traumática e suas sequelas, como pericardite traumática, inflamação do fígado, abscessos no baço e muito mais. Os sinais clínicos podem variar, mas incluem comportamento anormal, motilidade reduzida do rúmen, fezes mal digeridas, febre e sinais de dor. O diagnóstico baseia-se na avaliação dos sinais clínicos do animal, juntamente com exames complementares, como hemograma, bioquímico, ultrassom e radiografia. É importante considerar as alterações hematológicas, como leucocitose e hiperfibrinogenemia, como indicadores-chave desta afecção. O diagnóstico também envolve testes de dor ao corpo estranho. O tratamento pode ser conservativo ou cirúrgico. A abordagem conservativa envolve a administração de antibióticos, anti-inflamatórios e soluções intravenosas, além do tratamento de deficiências nutricionais subjacentes. A opção cirúrgica exige a remoção do corpo estranho do retículo, seguida de cuidados pós-operatórios.


Traumatic Reticulum Peritonitis this directly linked to the ingestion of sharp metallic objects, such as nails and pieces of wire, which can penetrate or pierce the wall of the reticulum. Although the occurrence of aluminum foreign bodies is rare, other elements, such as tire wires used to attach tarpaulins to silage and even wire bristles from brushes used in small airports, have been recorded as causes of this condition. Ingestion of these objects can result in damage to the reticulum, triggering episodes of traumatic reticulum peritonitis and its sequelae, such as traumatic pericarditis, liver inflammation, spleen abscesses and more. Clinical signs may vary but include abnormal behavior, reduced rumen motility, poorly digested feces, fever and signs of pain. The diagnosis is based on the evaluation of the animal's clinical signs, together with complementary tests, such as blood count, biochemistry, ultrasound and radiography. It is important to consider hematological changes, such as leukocytosis and hyperfibrinogenemia, as key indicators of this condition. Diagnosis also involves foreign body pain testing. Treatment can be conservative or surgical. The conservative approach involves administering antibiotics, anti-inflammatories and intravenous solutions, in addition to treating underlying nutritional deficiencies. The surgical option requires removal of the foreign body from the reticulum, followed by post-operative care.

ABSTRACT

SUMMARY: Cadmium (Cd) is the industrial and environmental toxic heavy metal which is found in air, water and soil. Cd, adversely affects many organs in humans such as kidney, intestine, liver, testis and lungs. L-carnitine (LC) is an important agent that plays essential role in energy metabolism. In our study, we aimed to work out whether LC application has any protective effect on intestinal contractility and morphologic damage of prepubertal rat duodenum on Cd-induced toxicity. Twenty eight prepubertal female Wistar rats were divided into four groups. The first group is control (C), second group; Cd group; Cadmium chloride was given 2 mg/kg 28 days with a one-day break by i.p. The third group; Cd+LC, which cadmium chloride was given 2 mg/kg i.p. and LC was given orally by gastric lavage. The LC dose was given as 75 mg/kg. The fourth group; LC, which only LC was given orally. The intestinal segments were isolated and suspended in tissue bath. Contractile responses were induced by acetylcholine (ACh) and relaxation was achieved with phenylephrine. Also the segments were examined for histological changes by light microscopy. Ach-induced contractions were higher in Cd+LC, LC, and control group compared to the Cd group in duodenal segments. The phenylephrine-induced relaxations were lower in Cd groups as compared with Control, Cd+LC and LC group in duodenal segments. In Cd group intestinal morphology was observed to be severely damaged whereas in Cd+LC group the damage was noticeably lower. Cd administration caused severe cellular damage and decreased gastrointestinal motility. Treatment with the LC has affected the gastrointestinal contractility and reduced the damage in intestinal morphology, which occured after Cd application.


El cadmio (Cd) es el metal pesado tóxico industrial y ambiental que se encuentra en el aire, el agua y el suelo. El Cd afecta negativamente a muchos órganos humanos, como los riñones, los intestinos, el hígado, los testículos y los pulmones. La L-carnitina (LC) es un agente importante que juega un rol esencial en el metabolismo energético. El objetivo de este estudio fue determinar si la aplicación de LC tiene algún efecto protector sobre la contractilidad intestinal y el daño morfológico del duodeno de rata prepuberal sobre la toxicidad inducida por Cd. Veintiocho ratas Wistar hembras prepúberes se dividieron en cuatro grupos. El primer grupo control (C), segundo grupo; grupo cd; Se administró cloruro de cadmio 2 mg/kg durante 28 días con un descanso de un día por vía i.p. El tercer grupo; Cd+LC, al que se administró cloruro de cadmio 2 mg/kg i.p. y LC se administró por vía oral mediante lavado gástrico. La dosis de LC se administró como 75 mg/kg. El cuarto grupo; LC, al cual solo LC se administraba por vía oral. Los segmentos intestinales fueron aislados y suspendieron en baño de tejido. Las respuestas contráctiles fueron inducidas por acetilcolina (ACh) y la relajación se logró con fenilefrina. También se examinaron los segmentos en busca de cambios histológicos mediante microscopía óptica. Las contracciones inducidas por Ach fueron mayores en Cd+LC, LC y el grupo control en comparación con el grupo Cd en los segmentos duodenales. Las relajaciones inducidas por fenilefrina fueron menores en los grupos Cd en comparación con el grupo Control, Cd+LC y LC en los segmentos duodenales. En el grupo Cd se observó que la morfología intestinal estaba severamente dañada mientras que en el grupo Cd+LC el daño fue notablemente menor. La administración de Cd causó daño celular severo y disminución de la motilidad gastrointestinal. El tratamiento con LC afectó la contractilidad gastrointestinal y redujo el daño en la morfología intestinal, que ocurría después de la aplicación de Cd.

ABSTRACT

In recent years, colonic manometry has been gradually introduced into clinical practice. It helps clinicians to gain a better understanding of the physiology and pathophysiology of colonic contractile activity in healthy adults and patients with colonic dysfunction. More and more patterns of colonic motility are being discovered with the help of colonic manometry. However, the clinical significance of these findings still needs to be further investigated. This review enhances our understanding of colonic motility and the current state of development and application of colonic manometry, as well as the limitations, future directions and potential of the technique in assessing the impact of treatment on colonic motility patterns, by analyzing and summarizing the literature related to colonic manometry.

ABSTRACT

SUMMARY: Ischemia-reperfusion (I/R) of the small intestine causes serious abdominal pathologies including tissue dysfunction and organ failure. L-carnitine (L-C), a powerful antioxidant, may help lessen the severity of these pathological effects since it plays a key role in energy metabolism. In this work we aimed to study the effects of L-C on the isolated ileal and duodenal contractility and histological changes in intestinal ischemia and reperfusion injury. Twenty eight Wistar rats were divided into four groups. The first group is the control group. Second group, I/R group, had rats submitted to 45-minutes of intestinal ischemia and to 45-minutes reperfusion. The third group, I/R+ L-C group, rats were treated with L-C 5 minutes before reperfusion and than submitted to ischemia. The fourth group, included rats that were treated with L-C without ischemia or reperfusion. Intestinal ischemia was conducted by obstructing superior mesentery arteries by silk loop. The ileal and duodenal segments were isolated and suspended in tissue bath. Contractile responses were induced by acetylcholine (Ach) and relaxation was achieved with phenylephrine. At the same time the terminal ileal and duodenal segments were examined for histological changes. Ach-induced contraction responses were higher in the I/R+L-C group, the L-C group, and the control group compared to the I/R group, in both ileal and duodenal segments. On the other hand, the phenylephrine-induced relaxations were higher in the I/R+L-C and L-C groups, especially in duodenal segments. In I/R group intestinal morphology was observed to be severely damaged whereas in I/R+L-C group the damage was noticeably lower possibly due to protective properties of L-C. I/R injury caused severe cellular damage response within the muscularis resulting in decreased gastrointestinal motility. Treatment with the L-C has significantly affected the gastrointestinal contractility. Also L-C treatment reduced the damage in intestinal morphology that occurs after IR injury.


RESUMEN: La isquemia-reperfusión (I/R) del intestino delgado provoca graves patologías abdominales que incluyen disfunción tisular y falla orgánica. La L-carnitina (L-C), un poderoso antioxidante, puede ayudar a disminuir la gravedad de estos efectos patológicos, ya que desempeña un papel clave en el metabolismo energético. El objetivo de este trabajo fue estudiar los efectos de L-C sobre la contractilidad ileal y duodenal aislada y los cambios histológicos en la lesión por isquemia y reperfusión intestinal. Se dividieron 28 ratas Wistar en cuatro grupos. El primer grupo fue el control. El segundo grupo, grupo I/R, de ratas sometidas durante 45 minutos de isquemia intestinal y a 45 minutos de reperfusión. El tercer grupo, grupo I/R+ L-C, las ratas se trataron con L-C, 5 minutos antes de la reperfusión y luego se sometieron a isquemia. El cuarto grupo, las ratas fueron tratadas con L-C sin isquemia ni reperfusión. La isquemia intestinal se realizó obstruyendo la arteria mesentérica superior con un asa de seda. Los segmentos ileal y duodenal se aislaron y suspendieron en un baño de tejido. Las respuestas contráctiles fueron inducidas por acetilcolina (Ach) y la relajación se logró con fenilefrina. Al mismo tiempo, se examinaron cambios histológicos de los segmentos del íleon terminal y del duodeno. Las respuestas de contracción inducidas por Ach fueron mayores en el grupo I/R+L-C, el grupo L-C y el grupo control en comparación con el grupo I/R, tanto en el segmento ileal como en el duodenal. Por otra parte, las relajaciones inducidas por fenilefrina fueron mayores en los grupos I/R+L-C y L-C, especialmente en los segmentos duodenales. En el grupo I/R se observó que la morfología intestinal estaba dañada significativamente, mientras que en el grupo I/R+L-C el daño fue notablemente menor, posiblemente debido a las propiedades protectoras de L-C. La lesión por I/R causó una respuesta de daño celular severo dentro de la capa muscular que resultó en una disminución de la motilidad gastrointestinal. El tratamiento con L-C afectó significativamente la contractilidad gastrointestinal. Por otra parte, el tratamiento L-C redujo el daño en la morfología intestinal que ocurre después de la lesión por IR.

ABSTRACT

Acupuncture regulating gastrointestinal motility has the characteristics of bidirectional benign regulation, acupoint specificity and immediacy. And its regulation is mainly achieved through the "neuro-endocrine-immune" network system. Acupuncture at Neiguan (PC 6) and Hegu (LI 4) to inhibit intestinal peristalsis may have good application value in colonoscopy.

ABSTRACT

OBJECTIVE@#To observe the effect of electroacupuncture (EA) at "Zusanli" (ST 36) combined with mosapride on gastric emptying rate and gastric motility in the rats with diabetic gastroparesis.@*METHODS@#Using random number table method, 68 male SD rats were divided into a blank group (12 rats) and a model establishment group (56 rats). In the model establishment group, the models of diabetic gastroparesis were established with intraperitoneal injection of streptozotocin combined with high-fat and high-sugar diet. Six weeks later, the successful rat models in the model establishment group were randomized into a model group, an EA group, a mosapride group and a combined treatment group, 12 rats in each one. In the EA group, EA was exerted at "Zusanli" (ST 36) (disperse-dense wave, 2 Hz/15 Hz in frequency, 2 mA in intensity) for 20 min. In the mosapride group, mosapride was intervened with intragastric administration (2 mg/kg). In the combined treatment group, electroacupuncture at "Zusanli" (ST 36) was combined with intragastric administration of mosapride. The intervention was given once daily in each group. There was 1 day at interval after 6-day intervention, consecutively for 5 weeks. At the end of intervention, the random blood glucose, gastric emptying rate and the data of gastric motility (average intra-gastric pressure, amplitude and frequency of gastric motility) were detected.@*RESULTS@#Compared with the blank group, blood glucose was increased in the model group (P<0.001). Blood glucose was reduced in the EA group, the mosapride group and the combined treatment group as compared with the model group separately (P<0.001, P<0.01), whereas, compared with the mosapride group, blood glucose was decreased in the combined treatment group (P<0.05). In comparison with the blank group, the gastric emptying rate, the average intra-gastric pressure and the amplitude of gastric motility were all decreased in the model group (P<0.001) and the frequency of gastric motility was increased (P<0.001). Gastric emptying rate, the average intra-gastric pressure and the amplitude of gastric motility were increased in the EA group, the mosapride group and the combined treatment group (P<0.01, P<0.05, P<0.001) and the frequency of gastric motility was decreased (P<0.001) as compared with the model group respectively. Compared with the EA group, the average intra-gastric pressure and the amplitude of gastric motility were increased in the combined treatment group (P<0.001). In comparison with the mosapride group, the gastric emptying rate, the average intra-gastric pressure, the amplitude and frequency of gastric motility in the combined treatment group, as well as the frequency of gastric motility in the EA group were all increased (P<0.05, P<0.001, P<0.01).@*CONCLUSION@#Electroacupuncture at "Zusanli" (ST 36) combined with intragastric administration of mosapride could regulate blood glucose and improve the gastric motility in the rats with diabetic gastroparesis. The effect is better than either simple electroacupuncture or mosapride.

ABSTRACT

Abstract Objective To investigate the effect of closure types of the anterior abdominal wall layers in cesarean section (CS) surgery on early postoperative findings. Methods The present study was designed as a prospective cross-sectional study and was conducted at a university hospital between October 2018 and February 2019. A total of 180 patients who underwent CS for various reasons were enrolled in the study. Each patient was randomly assigned to one of three groups: Both parietal peritoneum and rectus abdominis muscle left open (group 1), parietal peritoneum closure only (group 2), and closure of the parietal peritoneum and reapproximation of rectus muscle (group 3). All patients were compared in terms of postoperative pain scores (while lying down and duringmobilization), analgesia requirement, and return of bowel motility. Results The postoperative pain scores were similar at the 2nd, 6th, 12th, and 18th hours while lying down. During mobilization, the postoperative pain scores at 6 and 12 hours were significantly higher in group 2 than in group 3. Diclofenac use was significantly higher in patients in group 1 than in those in group 2. Meperidine requirements were similar among the groups. There was no difference between the groups' first flatus and stool passage times. Conclusion In the group with only parietal peritoneum closure, the pain scores at the 6th and 12th hours were higher. Rectus abdominismuscle reapproximations were found not to increase the pain score. The closure of the anterior abdominal wall had no effect on the return of bowel motility.

ABSTRACT

Este estudo teve por objetivo avaliar os efeitos da nutrição parenteral total ou enteral, associadas ou não à glutamina, sobre a motilidade gastrintestinal em equinos submetidos à inanição e realimentação. Foram utilizados 16 equinos adultos hígidos, sem raça definida, de ambos os sexos, quatro machos e 12 fêmeas, com idade variando entre quatro e 14 anos e peso corporal médio de 248,40 + 2,28 kg, divididos em quatro grupos, quatro animais por grupo: Grupo I (ENTGL): fluidoterapia enteral com eletrólitos associada a glutamina; Grupo II (PARGL): Nutrição parenteral total (NPT) associada a glutamina; Grupo III (ENTFL): fluidoterapia enteral com eletrólitos; Grupo IV (PARFL): fluidoterapia parenteral. O delineamento experimental foi inteiramente ao acaso, em um esquema fatorial 4x12 (grupos x tempo de colheita), para cada fase, e suas médias comparadas pelo teste de Duncan ao nível de 5% de significância. Independente do grupo experimental ocorreu redução da motilidade gastrintestinal durante a fase de inanição, mais pronunciada nos grupos PARGL e PARFL. Uma vez restabelecida a alimentação a motilidade gastrintestinal retornou à normalidade.


This study aimed to evaluate the effects of enteral or total parenteral nutrition, associated or not with glutamine, on gastrointestinal motility in horses subjected to starvation and refeeding. 16 healthy, mixed-breed adult horses of both sexes, four geldings and 12 mares, with ages ranging from four to 14 years and an average body weight of 248.40 + 2.28 kg, were divided into four groups, four animals per group: Group I (ENTGL): enteral fluid therapy with electrolytes associated with glutamine; Group II (PARGL): total parenteral nutrition (TPN) associated with glutamine; Group III (ENTFL): enteral fluid therapy with electrolytes; Group IV (PARFL): parenteral fluid therapy. The experimental design was entirely randomized, in a 4x12 factorial scheme (groups x harvest time), for each phase, and their means compared by the Duncan test at the level of 5% significance. Regardless of the experimental group, there was a reduction in gastrointestinal motility during the starvation phase, which was more pronounced in the PARGL and PARFL groups. Once the food was restored, gastrointestinal motility returned to normal.

ABSTRACT

The interplay between obesity and gastrointestinal (GI) motility is contradictory, and the transgenerational influence on this parameter is unknown. We aimed to evaluate the GI function in a model of paternal obesity and two subsequent generations of their male offspring. Newborn male rats were treated with monosodium glutamate (MSG) and composed the F1 generation, while control rats (CONT) received saline. At 90 days, male F1 were mated with non-obese females to obtain male offspring (F2), which later mated with non-obese females for obtaining male offspring of F3 generation. Lee Index analysis was adopted to set up the obesity groups. Alternating current biosusceptometry (ACB) technique was employed to calculate GI transit parameters: mean gastric emptying time (MGET), mean cecum arrival time (MCAT), mean small intestinal transit time (MSITT), and gastric frequency and amplitude of contractions. Glucose, insulin, and leptin levels and duodenal morphometry were measured. F1 obese rats showed a decrease in the frequency and amplitude of gastric contractions, while obese rats from the F2 generation showed accelerated MGET and delayed MCAT and MSITT. Glucose and leptin levels were increased in F1 and F2 generations. Insulin levels decreased in F1, F2, and F3 generations. Duodenal morphometry was altered in all three generations. Obesity may have paternal transgenerational transmission, and it provoked disturbances in the gastrointestinal function of three generations.

ABSTRACT

Aurantii Fructus is a commonly used qi-regulating medicinal herb in China. Both traditional Chinese medicine theory and modern experimental research demonstrate that Aurantii Fructus has dryness effect, the material basis of which remains unclear. In recent years, spectrum-effect relationship has been widely employed in the study of active ingredients in Chinese medicinal herbs, the research ideas and methods of which have been constantly improved. Based on the idea of spectrum-effect study, the ultra-high perfor-mance liquid chromatography-quadrupole-time of flight mass spectrometry(UHPLC-Q-TOF-MS) fingerprints of different fractions of Aurantii Fructus extract were established for the identification of total components. Then, the dryness effects of the fractions on normal mice and gastrointestinal motility disorder(GMD) rats were systematically compared. Finally, principal component analysis(PCA), Pearson bivariate correlation analysis and orthogonal partial least squares analysis(OPLS) were integrated to identify the dryness components of Aurantii Fructusextract. The results showed that narirutin, naringin, naringenin, poncirin, oxypeucedanin, and eriodictyol-7-O-glucoside had significant correlations with and contributed to the expression of AQP2 in kidney, AQP3 in colon, and AQP5 in submandibular gland, which were the main dryness components in Aurantii Fructus.

ABSTRACT

ABSTRACT BACKGROUND: Intestinal constipation (IC) in patients with the digestive form of Chagas disease is one of the main reasons for seeking medical care. Population data indicate that the practice of physical activity improves gastrointestinal motility. OBJECTIVE: This study evaluated the bowel frequency and symptoms of constipation and their relationship with the level of physical activity in patients with and without Chagas disease. METHODS: Patients (n=120) of both genres, aged between 35 and 84 years, in which 50% (n=60) were in the Chagas group and 50% (n=60) were in the control group, were evaluated regarding the level of IC using the Constipation Assessment Scale (CAS) and regarding the level of physical activity using the International Physical Activity Questionnaire (IPAQ). RESULTS - Patients in the Chagas group classified as active (IPAQ 2) had higher proportion (P=0.0235) of moderate IC with severe abdominal distension (P=0.0159) and decreased evacuation frequency (P=0.0281) than the patients in the control group, considered to be very active (IPAQ 1). The sedentary lifestyle was greater (P=0.0051) in the Chagas group with duration, intensity and frequency of physical activity lower than the control group. The health perception in the Chagas group was regular for 46.7% (P=0.0035) and poor for 8.3% (P=0.0244). CONCLUSION: There is a lower risk of developing intestinal constipation in more active individuals, evidencing that the level of physical activity interferes with bowel frequency and symptoms of constipation in patients with and without Chagas disease. The level of physical activity and health perception were worse in the Chagas group, reinforcing the disease stigma, which should be modified by the training of health professionals who routinely attend these patients.


RESUMO CONTEXTO: A constipação intestinal (CI) em pacientes com a forma digestiva da doença de Chagas é uma das principais razões para procura de atendimento médico. Os dados populacionais indicam que a prática de atividade física melhora a motilidade gastrointestinal. OBJETIVO: Este estudo avaliou a frequência intestinal e os sintomas de constipação e sua relação com o nível de atividade física em pacientes com e sem doença de Chagas. MÉTODOS: Pacientes (n=120) de ambos os gêneros, com idades entre 35 e 84 anos, nos quais 50% (n=60) eram do grupo Chagas e 50% (n=60) do grupo controle, foram avaliados quanto ao nível da CI utilizando a Escala de Avaliação da Constipação (CAS) e o nível de atividade física utilizando o Questionário Internacional de Atividade Física (IPAQ). RESULTADOS: Os pacientes do grupo Chagas classificados como ativos (IPAQ 2) apresentaram maior proporção (P=0,0235) de CI moderada com distensão abdominal grave (P=0,0159) e frequência de evacuação diminuída (P=0,0281) do que os pacientes do grupo controle, considerados muito ativos (IPAQ 1). O estilo de vida sedentário foi maior (P=0,0051) no grupo Chagas com duração, intensidade e frequência de atividade física menor que o grupo controle. A percepção de saúde no grupo Chagas foi regular para 46,7% (P=0,0035) e ruim para 8,3% (P=0,0244). CONCLUSÃO: Existe menor risco de desenvolver constipação intestinal em indivíduos mais ativos, evidenciando que o nível de atividade física interfere na frequência intestinal e nos sintomas de constipação em pacientes com e sem doença de Chagas. O nível de atividade física e percepção de saúde foram piores no grupo Chagas, reforçando o estigma da doença, que deve ser modificado pela capacitação dos profissionais de saúde que atendem rotineiramente esses pacientes.

ABSTRACT

O íleo paralítico é uma obstrução do tipo funcional, na qual o lúmen intestinal está patente, comprometendo a passagem da ingesta no intestino. Este relato objetiva descrever três casos em vacas com aptidão leiteira, atendidos na rotina hospitalar e diagnosticados com íleo paralítico. Em seus históricos, os proprietários queixavam-se que os animais apresentavam redução do apetite, timpania ruminal, diminuição da produção de leite e eliminação das fezes. Ao exame físico, alguns sinais clínicos apresentaram destaque, como apatia, desidratação, redução da motilidade ruminal e intestinal, fezes em pequena quantidade e com muco, distensão do abdômen e ao balotamento constatou-se a presença de líquido. Na análise do fluido ruminal todos os animais apresentaram o teor de cloreto elevado (>30 mEq/L), caracterizando, dessa forma, um processo obstrutivo. Diante dos achados, suspeitou-se inicialmente de um quadro de obstrução intestinal. Nos casos, a conduta adotada foi realizar uma laparotomia exploratória através do flanco direito, porém constatou-se, que não existia qualquer segmento com obstrução de natureza mecânica, que justificasse as alterações físicas e laboratoriais encontradas. Diante destes resultados, configurou-se um quadro clínico indicativo de íleo paralítico. As vacasforam submetidas a um protocolo terapêutico pós-cirúrgico composto por antibioticoterapia, anti-inflamatório, cálcio, procinético e tratamento de suporte. Os animais manifestaram uma resposta favorável a conduta terapêutica, com restabelecimento da função gastrointestinal e dos demais parâmetros fisiológicos, recebendo alta após uma evolução clínica variando entre dez a doze dias.


Paralytic ileus is an obstruction of the functional type, in which the intestinal lumen is patent, compromising the passage of the intake in the intestine. The objective of this study was to describe three cases in dairy cows treated in the hospital routine diagnosed with paralytic ileus. In their histories, the owners complained that the animals presented reduced appetite, ruminal tympany, decreased milk yield and elimination of faeces. At the physical examination, some clinical signs were prominent in both, such as apathy, dehydration, reduction of ruminal and intestinal motility, faeces were present in small quantity and with mucus present, abdominal enlargement and the succession produced sloshing sounds. In the analysis of the ruminal fluid, the chloride content in both was high (>30 mEq/L), characterizing an obstructive process. In the face of the findings, a diagnosis of intestinal obstruction was initially suspected. In animals, the adopted approach was to perform an exploratory laparotomy through the right flank, but it was verified that there was no segment with mechanical obstruction that justified the physical and laboratorial alterations found. In view of these results, a clinical diagnosis indicative of paralytic ileus was established. The three animals were submitted to a post-surgical therapeutic protocol consisting of antibiotic therapy, anti-inflammatory, calcium, pro-kinetic and supportive treatment. The animals showed a favourable response to therapeutic treatment, with restoration of gastrointestinal function and other physiological parameters, and was discharged after a clinical evolution ranging from ten to twelve days.

ABSTRACT

The current study was aimed to investigate the potential effects of perinatal exposure to therapeutic dose of penicillin and cefixime on the cognitive behaviors, gastrointestinal (GI) motility and serum 5-hydroxytryptamine (5-HT) level in the offspring. Pregnant rats were continuously treated with cefixime or penicillin in the period between 1 week before and 1 week after labor. Behavior tests, including social preference, self-grooming and elevated plus maze tests, and intestinal motility tests were carried out on the offspring at age of 4 to 10 weeks. Serum 5-HT levels were detected with ELISA, and potassium/sodium hyperpolarization activated cyclic nucleotide-gated channel 2 (HCN2) and tryptophan hydroxylase 1 (TPH1) expression levels in colon epithelium of offspring were detected by Western blot and RT-qPCR. The results showed that, compared with the naive group, cefixime increased social behavior in the female offspring, but did not affect the male offspring. Compared with the naive group, cefixime significantly decreased colonic and intestinal transits, and increased cecum net weight and standardized cecum net weight in the male offspring, but did not affect the female offspring. The serum 5-HT levels in the male offspring, rather than the female offspring, in cefixime and penicillin groups were significantly increased compared with that in the naive group. The protein expression level of HCN2 in colon epithelium of the offspring in cefixime group was significantly down-regulated, and the TPH1 expression level was not significantly changed, compared with that in the naive group. These results suggest that perinatal antibiotics exposure may affect neural development and GI functions of the offspring, and the mechanism may involve peripheral 5-HT and gender-dependent factor.

ABSTRACT

Stress is the non-specific systemic response that occurs when the body is stimulated by various factors, and it can affect multiple systems of the body. Recent studies have shown that gut microbiota is an essential part of human microecology, and plays a pivotal role in keeping the body healthy. Stress can result in gut dysbiosis by affecting the function of intestinal mucosal barrier, intestinal immune and gastrointestinal motility. This article reviewed the alteration of gut microbiota caused by stress and the possible mechanisms involved.

ABSTRACT

Abstract Purpose To investigate the effect of probiotics on spontaneous contractions of smooth muscle isolated from jejunum and ileum of rat model. Methods Four rat groups were created (n=8, in each) including control (Group 1), control+probiotic (Group 2), short bowel (Group 3), and short bowel+probiotic (Group 4). Groups 1 and 2 underwent sham operation, Groups 3 and 4 underwent massive bowel resection. Bifidobacterium Lactis was administered in Groups 2 and 4 daily (P.O.) for three weeks. On postoperative week 3, rats were sacrificed, and jejunum and ileum smooth muscle were isolated for organ bath. Muscle contraction changes were analyzed before and after addition of antagonists. Results Short bowel group exhibited increased amplitude and frequency of spontaneous contractions. The addition of probiotics significantly decreased enhanced amplitude and frequency of bowel contraction in short bowel group and returned to control values. L-NNA increased amplitude and frequency of contractions in all groups. While indomethacin and nimesulide increased the amplitude in all groups, the frequency was only increased in jejunum. Hexamethonium and tetrodotoxin did not change the contraction characteristics in all groups. Conclusion We suggest that early use of probiotics may significantly regulate bowel motility, and accordingly improve absorption of nutrients in short bowel syndrome.

ABSTRACT

ABSTRACT Background: High-resolution manometry is more costly but clinically superior to conventional manometry. Water-perfused systems may decrease costs, but it is unclear if they are as reliable as solid-state systems, and reference values are interchangeable. Aim: To validate normal values for a new water-perfusion high-resolution manometry system. Methods: Normative values for a 24-sensors water perfused high-resolution manometry system were validated by studying 225 individuals who underwent high resolution manometry for clinical complaints. Patients were divided in four groups: group 1 - gastroesophageal reflux disease; group 2 - achalasia; group 3 - systemic diseases with possible esophageal manifestation; and group 4 - dysphagia. Results: In group 1, a hypotonic lower esophageal sphincter was found in 49% of individuals with positive 24 h pH monitoring, and in 28% in pH-negative individuals. In groups 2 and 3, aperistalsis was found in all individuals. In group 4, only one patient (14%) had normal high-resolution manometry. Conclusions: The normal values determined for this low-cost water-perfused HRM system with unique peristaltic pump and helicoidal sensor distribution are discriminatory of most abnormalities of esophageal motility seen in clinical practice.


RESUMO Racional: A manometria de alta resolução é mais custosa, porém clinicamente superior à manometria convencional. Sistemas por perfusão de água podem ter custo diminuído, mas não é certo se são tão eficazes quanto aos sistemas de estado sólido e se os valores de referência são intercambiáveis. Objetivo: Este estudo visa validar valores de normalidade para um novo sistema por perfusão de água. Método: Valores de normalidade para um sistema de manometria de alta resolução de 24 sensores por perfusão de água foram validados estudando 225 indivíduos submetidos à manometria de alta resolução por queixas clínicas. Pacientes foram divididos em quatro grupos: grupo 1 - doença do refluxo gastroesofágico; grupo 2 - acalasia; grupo 3 - doenças sistêmicas com possível doenças sistêmicas com comprometimento esofágico; e grupo 4 - pacientes com disfagia. Resultado: No grupo 1, esfíncter esofagiano inferior hipotônico foi encontrado em 49% dos indivíduos com pHmetria positiva e 28% daqueles com pHmetria negativa. Nos grupos 2 e 3, aperistalse foi encontrada em todos indivíduos. No grupo 4, somente um paciente (14%) tinha manometria normal. Conclusão: Os valores de normalidade definidos para este sistema de manometria de alta resolução por perfusão de água são discriminatórios da maioria das anormalidades da motilidade esofágica vistas na prática clínica.

ABSTRACT

ABSTRACT Background: Gastrointestinal disorders are frequently reported in patients with Parkinson's disease whose disorders reduce the absorption of nutrients and drugs, worsening the clinical condition of patients. However, the mechanisms involved in modifying gastrointestinal pathophysiology have not yet been fully explained. Aim: To evaluate its effects on gastrointestinal motility and the involvement of the vagal and splanchnic pathways. Methods: Male Wistar rats (250-300 g, n = 84) were used and divided into two groups. Group I (6-OHDA) received an intrastriatal injection of 6-hydroxydopamine (21 µg/animal). Group II (control) received a saline solution (NaCl, 0.9%) under the same conditions. The study of gastric emptying, intestinal transit, gastric compliance and operations (vagotomy and splanchnotomy) were performed 14 days after inducing neurodegeneration. Test meal (phenol red 5% glucose) was used to assess the rate of gastric emptying and intestinal transit. Results: Parkinson's disease delayed gastric emptying and intestinal transit at all time periods studied; however, changes in gastric compliance were not observed. The delay in gastric emptying was reversed by pretreatment with vagotomy and splanchnotomy+celiac gangliectomy, thus suggesting the involvement of such pathways in the observed motor disorders. Conclusion: Parkinson's disease compromises gastric emptying, as well as intestinal transit, but does not alter gastric compliance. The delay in gastric emptying was reversed by truncal vagotomy, splanchnotomy and celiac ganglionectomy, suggesting the involvement of such pathways in delaying gastric emptying.


RESUMO Racional: Distúrbios gastrintestinais são frequentemente relatados em pacientes com doença de Parkinson cujos distúrbios reduzem a absorção de nutrientes e fármacos, agravando o quadro clínico dos pacientes. No entanto, os mecanismos envolvidos na alteração da fisiopatologia gastrintestinal ainda não foram totalmente elucidados. Objetivo: Avaliar os seus efeitos sobre a motilidade gastrintestinal e o envolvimento das vias vagal e esplâncnica. Métodos: Ratos Wistar machos (250-300 g, n=84) foram utilizados e divididos em dois grupos. O grupo I (6-OHDA) recebeu injeção intraestriatal de 6-hidroxidopamina (21 µg/animal). O grupo II (controle) recebeu solução salina (NaCl, 0,9%) nas mesmas condições. O estudo do esvaziamento gástrico, trânsito intestinal, complacência gástrica e operações (vagotomia e esplancnotomia) foram realizadas 14 dias após a indução da neurodegeneração. Refeição teste (vermelho de fenol+glicose 5%) foi utilizada para avaliar a taxa de esvaziamento gástrico e o trânsito intestinal. Resultados: A doença de Parkinson retardou o esvaziamento gástrico e o trânsito intestinal em todos os tempos estudados; porém, alterações da complacência gástrica não foram observadas. O retardo do esvaziamento gástrico foi revertido por pré-tratamento com vagotomia e esplancnotomia+gangliectomia celíaca, sugerindo assim, o envolvimento de tais vias nos distúrbios motores observados. Conclusão: A doença de Parkinson compromete o esvaziamento gástrico, bem como o trânsito intestinal, mas não altera a complacência gástrica. O retardo do esvaziamento gástrico foi revertido pela vagotomia troncular, esplancnotomia e gangliectomia celíaca, sugerindo o envolvimento de tais vias no retardo do esvaziamento gástrico.

ABSTRACT

PURPOSE: We investigated the effect of delayed elevation of thyrotropin (TSH) (deTSH) on gastrointestinal motility in very low birth weight infants (VLBWI). METHODS: This study retrospectively investigated 228 premature VLBWI aged ≥4 weeks with normal neonatal TSH screening test results and free serum thyroxine levels. Infants with serum TSH levels ranging from 5 to 10 µIU/mL were categorized as the deTSH group (n=76), when TSH was measured at 4 (n=53), 8 (n=20), or 12 (n=3) weeks of age. Serum TSH levels in the control group (n=152) were <5 µIU/mL. Multivariate logistic regression analysis was used to determine the risk factors for the development of deTSH. Covariance analysis was used to analyze the relationship between deTSH and gastrointestinal motility. RESULTS: The mean gestational age and birth weight were 29.11±2.25 weeks and 1,157.4±218.0 g, respectively. Risk factors affecting deTSH were dopamine administration (odds ratio [OR], 8.71; 95% confidence interval [CI], 1.80 to 42.05; P=0.007) and operation time (OR, 6.95; 95% CI, 1.43 to 33.75; P=0.016) when the cumulative operating time was ≥1 hour. The mean±standard deviation (SD) duration of a nil per os (NPO) status was significantly higher in the deTSH (99.57±134.99 hours) than in the control group (37.25±59.02 hours) (P from analysis of covariance [ANCOVA]=0.001). The mean±SD duration (33.84±22.34 days) of total parenteral nutrition (TPN) was considerably longer in the deTSH group than in the control group (27.68±13.08 days) (P from ANCOVA=0.003). CONCLUSION: Clinicians must consider deTSH in VLBWI showing feeding intolerance with a prolonged NPO and TPN status.
