ABSTRACT

The objective of this study was to describe the clinical and pathological aspects of diseases of the digestive system in agoutis (Dasyprocta leporina Linnaeus, 1758) diagnosed by the "Laboratório de Patologia Veterinária" (Veterinary Pathology Laboratory) of the "Universidade Federal Rural do Semi-Árido" (UFERSA), from January 2018 to February 2020. During the study period, necropsy and a survey of the clinical history of 27 agoutis were performed, 25.93% (7/27) of which were diagnosed with digestive system diseases. The percentages of digestive tract diseases among the diagnosed were: acute carbohydrate overload (11.12%), gastric ulcer (7.41%), gastric volvulus (3.70%), and intestinal volvulus (3.70%). Studies on the occurrence rate of these diseases, as well as the description of their clinical and anatomopathological aspects, may serve as a basis for guiding the appropriate management in the breeding of these animals.(AU)

ABSTRACT

Numerous studies have demonstrated that Radix Astragali can inhibit gastric ulcers in mice. Anhydrous ethanol (0.01 mL/g) administered to mice by intragastric infusion can induce gastric ulcer injury. This study was performed to compare the stomach tissue distribution profiles of four major bioactive constituents of Radix Astragali(calycosin-7-O-ß-d-glucoside, calycosin, ononin and formononetin) after oral administration of extract of Radix Astragali (ERA)in normal and gastric ulcer mice. The abundance of Radix Astragali constituents was determined using an ultra-pressure liquid chromatograph with a photodiode array detector (UPLC-PDA), after which histograms were drawn. In comparison with normal mice, the contents of calycosin- 7-O-ß-d-glucoside, calycosin, ononin and formononetin in the stomach tissue samples of gastric ulcer mice showed significant differences at the selected time points (P < 0.05).The abundance of each of the four tested constituents in the normal groups was higher than that of the gastric ulcer groups. This study provides an empirical foundation for future studies focused on developing clinical applications of Radix Astragali

ABSTRACT

: To investigate the protective effect of (FD) against ethanol-induced gastric ulcer and its mechanism. : Human gastric epithelial GES-1 cells were divided into normal control group, model control group, FD 95% alcohol extract group, FD 50% alcohol extract group and FD decoction extract group. Gastric ulcer was induced by treatment with 1% ethanol in GES-1 cells. The cell proliferation was detected with MTT method in each group. Sixty SD rats were randomly divided into normal control group, model control group, ranitidine group and low-dose, medium-dose, high-dose FD 95% alcohol extract groups (150, 300, 600 mg/kg). The corresponding drugs were administrated by gavage for The gastric ulcer model was induced by intragastric administration of anhydrous ethanol. The gastric ulcer area and ulcer inhibition rate of rats were measured in each group; the degree of gastricmucosal damage was observed by scanning electron microscopy; the levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β in serum and the content of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), catalase (CAT) in gastric tissues were detected by ELISA method. : 95% alcohol extract of FD had the strongest protective effect on proliferation of GES-1 cells. In animal experiments, compared with the normal control group, a large area of ulcers appeared on the gastric mucosa in the model control group, while the ulcer areas of the FD groups and ranitidine group were significantly smaller than that of the model control group (all <0.05). Compared with the model control group, FD groups and ranitidine group significantly reduced the levels of TNF-α, IL-1β, IL-6 in serum and the MDA content in the gastric tissues, and increased the activity of SOD, CAT and GSH in gastric tissues (all <0.05). : The 95% alcohol extract of FD can reduce the levels of TNF-α, IL-1β and IL-6 in serum and the content of MDA in gastric tissues, and increase the activity of SOD, CAT and GSH in gastric tissues to achieve the protective effect against gastric ulcer.

ABSTRACT

Sow mortality is directly related to financial losses and productive efficiency in pig farms. Despite this, diseases associated with the death of sows are poorly understood. This study aimed to determine the main causes of death of sows in Brazilian pig farms. To perform this research, three Brazilian pig farms were visited, and necropsies were performed on all sows that had died spontaneously or were subjected to euthanasia. Tissue fragments were collected for histopathological and bacteriological examination. In addition, the clinical signs, productive stage, parity, and type of death (spontaneous or euthanasia) were recorded. A total of 138 necropsies were performed, and 132 had a conclusive diagnosis. The most frequent productive stages were gestation and lactation (33.3 and 31.9%, respectively), followed by parturient sows (17.4%), cull sows (9.4%), weaning-to-estrus interval (WEI) (4.3%), and unmated gilts (3.6%). The most affected organ systems were reproductive (28%), digestive (25%), locomotor (22%), cardiovascular (9.1%), and hematopoietic (6.1%). The most frequently diagnosed conditions were uterine prolapse (16/132; 12.1%), gastric ulcer (13/132; 9.8%), suppurative arthritis (11/132; 8.3%), liver lobe torsion (11/132; 8.3%), heart failure (9/132; 6.8%), vaginal or vaginal and rectal prolapse (9/132; 6.8%), and pododermatitis (8/132; 6.1%). Although 58.2% of the deaths were due to one of these seven diseases, there was a great variability in diagnoses.(AU)


A mortalidade de porcas está diretamente relacionada a perdas financeiras e à eficiência produtiva das granjas. Apesar disso, as doenças associadas à morte de porcas são pouco conhecidas. Este estudo teve como objetivo determinar as principais causas de morte de porcas em granjas suinícolas brasileiras. Para a realização desta pesquisa, três granjas brasileiras foram visitadas e necropsias foram realizadas em todas as porcas que morreram espontaneamente ou foram submetidas à eutanásia. Fragmentos de tecidos foram coletados para exame histopatológico e bacteriológico. Além disso, foram registrados os sinais clínicos, estágio reprodutivo, ordem de parto e tipo de morte (espontânea ou eutanásia). Um total de 138 necropsias foram realizadas e 132 tiveram um diagnóstico conclusivo. Os estágios produtivos mais frequentes foram gestação e lactação (33,3 e 31,9%, respectivamente), seguidos por porcas parturientes (17,4%), porcas de descarte (9,4%), intervalo desmame-estro (IDE) (4,3%) e leitoas vazias (3,6%). Os sistemas orgânicos mais afetados foram reprodutor (28%), digestivo (25%), locomotor (22%), cardiovascular (9,1%) e hematopoiético (6,1%). As condições mais frequentemente diagnosticadas foram prolapso uterino (16/132; 12,1%), úlcera gástrica (13/132; 9,8%), artrite supurativa (11/132; 8,3%), torção do lobo hepático (11/132; 8,3%), insuficiência cardíaca (9/132; 6,8%), prolapso vaginal ou prolapso vaginal e retal (9/132; 6,8%) e pododermatite (8/132; 6,1%). Embora 58,2% dos óbitos tenham ocorrido por uma dessas sete doenças, houve grande variabilidade de diagnósticos.(AU)

ABSTRACT

The occurrence of gastrointestinal myiasis caused by Gasterophilus spp. larvae (Diptera: Oestridae) in adult horses has been widely characterized, however data on natural infestation in young foals have been lacking. This observation may be related to the absence of conclusive diagnosis in these individuals, most likely due to logistical or financial constraints. Gastric ulceration is a problem and a significant cause of morbidity in foals, particularly during the weaning stage; therefore, gasterophilosis should be included in the differential diagnosis. The primary purpose of this study was to determine the prevalence of gasterophilosis in 4- to 6-month-old weanling foals. Seventy-one healthy weanling foals were enrolled in the study. Physical assessment blood sampling and was completed in all foals before the commencement of the experiment. Gastroscopy examinations were performed under sedation (Detomidine 0.01 - 0.02 mg/kg) with a flexible endoscope inserted through nasogastric via. The lumen of the stomach was examined in order to search for botflies' larvae. Following gastroscopy, foals were classified into 2 groups based on the presence of Gasterophilus spp. larvae in their stomachs: 1) Infected and 2) Not Infected. Infected foals received a single dose of commercial trichlorfon and albendazole equine oral gel and were stalled for 24 h. The passed feces were thoroughly examined, searching for elimination of larvae. A total of 64% of the foals (n = 45/71) harbored Gasterophilus spp. larvae in the stomach. Mild hyperemia in the gastric mucosa was observed in the attachment sites of the parasites. Physical assessment and hematological parameters' data were analyzed with Shapiro-Wilk normality test. Comparison between groups for clinical signs, hematological parameters and Gasterophilus spp. infection rates were evaluated using the Kruskal-Wallis test or Student's t-test. Statistical significance was set at P < 0.05. There were no statistically significant variations in physical and hematological parameters between foals that were affected and those that were not infected. The larvae found in the feces were subjected to morphological examination, which confirmed the diagnosis of Gasterophilus intestinalis. No systemic clinical indications compatible with Gasterophilus spp. infestation were seen, as described in previous studies of horses infected with the parasite. No botfly eggs were observed in the hair of evaluated foals. During gastroscopy, mild hyperemic lesions in the gastric mucosa were observed in the larvae fixation sites. Although no changes in clinical or hematological parameters were noted, the confirmation of parasite presence is a cause for concern due to horses' tolerance for low infestation levels and poor diagnosis. Additionally, the presence of this myiasis in foals may be a significant stressor during the weaning period and should be included in the differential diagnosis of recurring abdominal pain. Furthermore, infected foals might be a reservoir for the parasite and, contribute to the elimination and spread of the larvae in the environment. Thus, inclusion of young horses in deworming protocols targeted to botfly larvae is needed. This is the first report of Gasterophilus intestinalis myiasis in foals in Brazil. Further research is necessary to fully understand the epidemiology and prevalence of this condition in young horses in Brazil, based on the findings of this study.(AU)

ABSTRACT

The aim of this study was to investigate the main causes of death in growing-finishing pigs in southern Brazil. During a one-year period (from 2018 to 2019), two industrial pig herds (18 and 20 thousand pigs each farm) in southern Brazil were monitored along the four seasons of the year (12 days per season on each farm), in order to perform necropsies of all pigs that died in that period. The two farms had an average monthly mortality rate ranging from 0.94 to 3.93% in the evaluated months. At necropsy, tissues were collected, fixed in 10% formalin solution and processed routinely for histopathological examination. When necessary, samples were sent for bacterial culture and PCR to identify etiologic agents. A total of 601 necropsies were performed, with 94.9% of conclusive diagnoses. Infectious diseases corresponded to 64.4% of conclusive diagnosis and non-infectious diseases to 35.6%. The most prevalent causes of death were: pneumonia (33%), gastric ulcers (15.4%), circovirosis (9.9%), systemic bacterial embolism (5.4%), polyserositis (4.4%), dilated cardiomyopathy and torsion of abdominal organs (4.3% each), and bacterial pericarditis (3.4%). Regarding pneumonias (199/601), the main agents identified in these cases were Pasteurella multocida, Influenza A virus and Mycoplasma hyopneumoniae, mainly in associations.(AU)


O objetivo do presente trabalho foi investigar as principais causas de morte de suínos em fase de crescimento e terminação no Sul do Brasil. Durante o período de um ano (entre 2018 e 2019), duas granjas tecnificadas de suínos no Sul do Brasil foram acompanhadas nas quatro estações (12 dias por estação em cada granja), para realização de necropsias dos suínos que morreram nesse período. As duas propriedades apresentavam mortalidade mensal média entre 0,94 e 3,93% nos meses avaliados. Na necropsia, amostras de órgãos foram colhidas, fixadas em formol 10% e processadas rotineiramente para o exame histopatológico. Quando necessário, amostras foram enviadas para o cultivo bacteriano e PCR para identificação de agentes etiológicos. Foram realizadas um total de 601 necropsias, com 94,9% de diagnósticos conclusivos. As doenças infecciosas corresponderam a 64,4% dos diagnósticos conclusivos e as não infecciosas a 35,6%. As principais causas de morte foram: pneumonias (33%), úlcera gástrica (15,4%), circovirose (9,9%), embolia bacteriana sistêmica (5,4%), polisserosite (4,4%), cardiomiopatia dilatada e torção de órgãos abdominais (4,3% cada) e pericardite bacteriana (3,4%). Com relação às pneumonias (199/601), os principais agentes associadas as lesões foram Pasteurella multocida, vírus da Influenza A e Mycoplasma hyopneumoniae, principalmente associados entre si.(AU)

ABSTRACT

Solanum nigrum (SLN), commonly known as African nightshade, is used as a vegetable as well as in the management and treatment of various ailments including gastric ulcers. We analyzed, both grossly and microscopically using H&E, Masson's trichrome and PSA staining methods, the protective effects of aqueous leaf extracts of three Kenyan SLN genotypes namely S. scabrum (SSB), S. sarrachoides (SSR) and S. villosum (SVL) on ethanol-induced gastric lesions in rats. There was evidence of gastro-protection by all the three genotypes with the SSB showing the highest ulcer inhibition score (76.37 %) followed by SSR (72.51 %) and SVL (63.30 %). SLN-pretreated rats showed less areas of gastric mucosal surface erosion. Additionally in the pretreated animals, the depth of the ulcers were markedly reduced, reaching only the gastric pit region except in those treated with SVL where the ulcers penetrated slightly more deeply to affect the gastric glands. Compared with controls, the mean microscopic ulcer index decreased 5.07, 3.55 and 2.37-fold in rats pretreated with SSB, SSR and SVL extracts respectively. Results of this work show extracts of the three SLN genotypes to have antiulcerogenic potential but at varied strengths, thus confirming earlier reports that phytoconstituents and hence the efficacy of a medicinal plant may be influenced by genetic factors.


Solanum nigrum (SLN), comúnmente conocida como la solanácea africana, se usa como vegetal, para el tratamiento de diversas dolencias incluyendo las úlceras gástricas. Analizamos de forma macro y microscópica, de forma macroscópica y microscópica, utilizando para ello tinciones de H&E, tricrómico de Masson y PSA los efectos protectores de extractos acuosos de hojas de tres genotipos SLN de Kenia: S. scabrum (SSB), S. sarrachoides (SSR) and S. villosum (SVL) en lesiones gástricas inducidas por etanol en ratas. Hubo evidencia de gastroprotección por parte de los tres genotipos con el SSB mostrando el puntaje más alto de inhibición de la úlcera (76,37 %) seguido de SSR (72,51 %) y SVL (63,30 %). Las ratas tratadas previamente con SLN mostraron menos áreas de erosión de la superficie de la mucosa gástrica. Además, en los animales pretratados, la profundidad de las úlceras se redujo notablemente, llegando solo a la región del fondo gástrico, excepto en aquellos tratados con SVL donde las úlceras penetraron un poco más profundamente para afectar las glándulas gástricas. En comparación con los controles, el índice medio de úlcera microscópica disminuyó 5,07, 3,55 y 2,37 veces en ratas pretratadas con extractos de SSB, SSR y SVL, respectivamente. Los resultados de este trabajo muestran que los extractos de los tres genotipos de SLN tienen potencial antiulcerogénico en diferentes concentraciones, lo que confirma informes anteriores que los fitoconstituyentes y la eficacia de una planta medicinal pueden estar influenciados por factores genéticos.

ABSTRACT

Se evaluó la actividad gastroprotectora de la infusión proveniente de las hojas de Aloysia gratissima (Verbenaceae), especie nativa de interés medicinal que se desarrolla en el sudoeste bonaerense, utilizando un modelo de inducción de úlceras gástricas con etanol en ratones. Se realizó un tamizaje fitoquímico para detectar la presencia de compuestos que podrían ser responsables de la actividad gastroprotectora de la planta. Se determinó el contenido de fenoles totales y la capacidad atrapadora de radicales libres mediante el método del Folin-Ciocalteu y del 2,2'-difenil-1-picrilhidrazilo (DPPH), respectivamente. Los ensayos demostraron que la infusión de la planta, administrada por vía oral en dosis de 100, 500 y 1000 mg/kg, ejerció una gastroprotección significativa frente a la inducción de úlceras. Se detectó una actividad atrapadora de radicales libres de 47,5%, similar a la sustancia de referencia (BHT). El estudio fitoquímico detectó la presencia de flavonoides y otros polifenoles, sustancias con reconocida capacidad antioxidante. Estos metabolitos ejercen efectos protectores en diferentes modelos experimentales de inducción de úlceras mediante mecanismos que pueden involucrar la neutralización de radicales libres, lo que podría explicar la actividad gastroprotectora de la planta. Estos hallazgos requieren estudios adicionales de A. gratissima como una posible terapia frente a la úlcera gástrica. (AU)


The gastroprotective activity of the infusion from the leaves of Aloysia gratissima (Verbenaceae), a native species of medicinal interest growing in South West Buenos Aires, was evaluated in an ethanol-induced gastric ulcer model in mice. Phytochemical screening was carried out in order to determine the presence of compounds that could be responsible for the pharmacological effects of the plant. Total phenolic content and the free radical scavenging activity of the plant were determined using the Folin-Ciocalteu and the 2,2'-diphenyl1-picrylhydrazyl (DPPH) method, respectively. Assays demonstrated that the infusion, orally administered at 100, 500, and 1000 mg/kg doses, exerted a significant gastroprotection effect against ulcer induction (P<0,05). A free radical scavenging activity of 47.5% -similar to the reference substance (BHT)- was detected. Phytochemical screening revealed the presence of antioxidant compounds such as flavonoids and other phenolic compounds. These compounds exert protective effects in different experimental models of ulcer induction that could involve free radical neutralization, which could explain the gastroprotective activity of the plant. These promising results support additional studies of A. gratissima as a potential therapy against gastric ulcer. (AU)

ABSTRACT

An 11-year (2007-2018) survey of epidemiological, clinical and pathological findings of horses with primary gastric rupture (PGR) was conducted. Twenty horses presented PGR, nine (45%) horses were clinically evaluated, eleven (55%) were sent dead, and all animals were necropsied. PGR contributed to a prevalence of 0.31% (9/2,868) of all equid attendances, 1.83% (9/491) of colic cases, and 4.1% (20/487) of all equid necropsies. Highly fermentable feed (n=7), gastric impaction (n=4), and perforating gastric ulcer (n=1) were the main causes of PGR; whilst eight horses presented idiopathic gastric rupture. Clinically evaluated horses were tachycardic, tachypneic, febrile, dehydrated, with increased abdominal tension, abnormal mucous membranes and reduced to absent intestinal borborygmi. Improper dietary management, such as the ingestion of low-quality roughage and highly fermentable feedstuffs were detected as the main factors associated with PGR in Midwestern Brazil. It is important to raise awareness in horse owners about proper feed management to minimize PGR.(AU)


Foi realizado um levantamento de 11 anos (2007-2018) dos achados epidemiológicos, clínicos e patológicos de equinos com ruptura gástrica primária (RGP). Vinte equinos apresentaram RGP, dos quais nove (45%) foram avaliados clinicamente e 11 (55%) foram enviados mortos, sendo todos os animais necropsiados. A RGP contribuiu com prevalência de 0,31% de todos os atendimentos de equídeos (9/2.868), 1,83% (9/491) dos casos de cólica, e 4,1% (20/487) das necropsias em equídeos. Alimentos altamente fermentáveis (n=7), compactação gástrica (n=4) e perfuração de úlcera gástrica (n=1) foram as principais causas de RGP, enquanto oito equinos tiveram ruptura gástrica idiopática. Os equinos avaliados clinicamente apresentaram-se taquicárdicos, taquipneicos, febris, desidratados, com mucosas anormais, aumento da tensão abdominal e motilidade intestinal reduzida. O manejo inadequado da dieta, como a ingestão de forragens de baixa qualidade e alimentos altamente fermentáveis, foi o principal fator de risco associado à RGP no Centro-Oeste do Brasil. É importante aumentar a conscientização dos proprietários de equinos sobre o manejo alimentar adequado para minimizar a RGP.(AU)

OBJECTIVES@#To detemine preventive effects of compound formula Rhizoma Coptidis and Atractylodes on mice with gastric-ulcer.@*METHODS@#The mice were randomly divided into a normal group, a gastric ulcer group, a ranitidine positive drug group, a Rhizoma Coptidis group, an Atractylodes group, and a Rhizoma Coptidis plus Atractylodes group (the ratios of Coptidis to Atractylodes were 9꞉1, 8꞉2, 7꞉3, 6꞉4, 5꞉5, or 4꞉6, respectively). Gastric ulcer models were established by intragastric administration of anhydrous ethanol after 6 days of preventive infusion. The mice were killed 6 days after the treatments. The whole stomach was opened to observe gross morphology of gastric mucosa. The pathological changes of gastric tissue were observed under microscope, and serum samples were collected to detect the contents of superoxide dimutase (SOD), malondialdehyde (MDA), NO, and endothelin-1 (ET-1).@*RESULTS@#The Rhizoma Coptidis and Atractylodes decoction significantly decreased ulcer area (<0.001), and the effects of compound formula are better than those of Coptidis and Atractylodes alone (<0.05, <0.01, or <0.001). The anti-ulcer effect of compound formula (Coptidis꞉Atractylodes=6꞉4) was the best one, and the anti-gastric ulcer effect of the high-dose group was significantly better than that of the ranitidine-positive group (<0.001). The ranitidine positive drug group, the high-dose group of Rhizoma Coptidis, the high-dose group of Atractylodes, and the high-dose group of Rhizoma Coptidis-Atractylodes (6꞉4) significantly reduced MDA, ET-1 (<0.01 or <0.001), and significantly increased SOD, NO in serum (<0.01 or <0.001).@*CONCLUSIONS@#Rhizoma Coptidis and Atractylodes decoction exerts the effect on preventing ethanol-induced gastric ulcer in mice in a ratio-dependent and dose-dependent manner. The mechanism might be related to anti-oxidation and relaxion of blood vessels. The combination of the two drugs shows a synergistic effect.

ABSTRACT

Abstract Nonsteroidal anti-inflammatory drugs (NSAID) are among the aggressive factors causing gastric ulcer. They cause oxidative damage in the gastric tissue and lead to intracellular calcium deposition. Lercanidipine is a calcium channel blocker derived from the third generation dihydropyridine. The aim of this study is to analyse the effect of lercanidipine on indomethacin-induced gastric ulcers. A total of 24 albino Wistar male rats were divided into four groups; those who received indomethacin 25 mg/kg (IND), 5 mg mg/kg lercanidipine +25 mg/kg indomethacin (LC-5), 10 mg/kg lercanidipine+25mg/kg indomethacin (LC-10) and healthy rats who received 0.5 mL distilled water. Six hours after the application of indomethacin, the animals were sacrificed by high dose thiopental sodium. The stomachs of the animals were excised to perform a macroscopic analysis and the ulcerous region was measured on millimeter paper. All the stomachs were subjected to a biochemical analysis. Macroscopic analysis revealed hyperaemia on the gastric surface of the indomethacin group. Ulcerous tissues formed by oval, circular or irregular mucosal defects in varying diameters and depths were observed on the whole surface of the stomach. Hyperaemia was lower and ulcerous region was smaller in groups LC-5 and LC-10 compared to IND group. Malondialdehyde and myeloperoxidase levels were significantly lower and total glutathione and cyclooxygenase-1 activity were higher in groups LC-5 and LC-10. Lercanidipine did not change the cyclooxygenase-2 activity. Lercanidipine in doses 10 mg/kg is more effective compared to 5 mg/kg. Lercanidipinine can be useful in the treatment of NSAID-induced gastric damage.

ABSTRACT

The aim of this study was to determine the occurrence of EGUS and to quantify serum gastrin levels in jumping horses during competition season and interseason period. Forty jumping horses, competing at high level were randomly allocated into two groups, the Training Group: twenty jumping horses undergoing intense training and participating in competitions, and the Rest Group: twenty jumping horses in the interseason (resting period). The gastroscopic examinations and blood samples of the horses in the training group were performed 1-2 days following the competition while in the horses of the rest group, following 4 weeks of rest. The serum gastrin levels were measured at two different times: pre-feeding and two hours after feeding the horses (postprandial) by ELISA kit. Gastric lesion score data were compared by the Mann-Whitney U test (α= 0.05) and the mean gastrin values were compared between the groups and between the two moments by the paired tet tests, respectively (α= 0, 05). Squamous gastric ulcers were detected in 42.5% of all jumping horses examined independent of the period, competition season or interseason. Serum gastrin levels were significantly higher in the Training Group with no difference between pre-feeding and postprandial values.(AU)


O objetivo deste estudo foi determinar a ocorrência de EGUS e quantificar os níveis séricos de gastrina em cavalos de hipismo durante a época de competições e o período de férias. Quarenta cavalos de hipismo de alta performance foram aleatoriamente distribuídos em dois grupos, grupo treinamento: vinte cavalos de hipismo submetidos a treinamento intenso e participando de competições, e grupo descanso: vinte cavalos de hipismo em férias (período de descanso). As avaliações gastroscópicas e as coletas de sangue dos cavalos em treinamento foram realizadas um ou dois dias após as competições, enquanto nos cavalos do grupo descanso foram realizadas após quatro semanas de repouso. Os níveis séricos de gastrina foram mensurados por kit de ELISA, em dois momentos: antes da alimentação e duas horas após. Os dados de escore das lesões gástricas foram comparados pela prova U de Mann-Whitney (α= 0,05) e os valores médios de gastrina foram comparados entre os grupos e entre os dois momentos pelos testes t e t pareado, respectivamente (α= 0,05). Foram encontradas úlceras gástricas em 42,5% de todos os cavalos examinados, independentemente do período de competições ou repouso. Os níveis séricos de gastrina foram significativamente maiores no grupo treinamento, sem diferença entre os períodos pré e pós-alimentação.(AU)

ABSTRACT

Infection with Helicobacter pylori is a worldwide problem. It plays an important role in gastric malignancies.The pathogenesis of gastric malignancies involves multistep progression changes in gastric mucosa and the Helicobacter pylori infections is the first step in most of cases.Aim:The aims of this study were to clarify the benign changes in gastric mucosa after Helicobacter pylori infection;to evaluate the endoscopic and histological patterns of infection and to correlate endoscopic findingwith histopathological parameters.Materials and Methods:A descriptive, retrospective study was done in Soba University Hospital between January 2009 - February2013. Paraffin-embedded blocks, Giemsa and Haematoxylin and Eosin-stained slides, were obtained from 50 cases of Helicobacter pylori-associated chronic gastritis and examined under light microscopy. The clinical information and endoscopy findings were obtained from the records. The data was analyzed using Statistical Package for Social Sciences Software.Results:The most common affected age group was between 40-60 years. The prevalence of infection was equal in males and females. The commonest endoscopic finding was inflammation of gastric mucosa. Most patients presented with moderate degree of colonization; 62% of patients presented with a severe degree of chronic inflammation. There was a significant statistical correlation between the degree of Helicobacter pylori colonization and the degree of chronic inflammation (p<0.05). Most patients presented with severe degree of active gastritis. A significant correlation was found between the degree of chronic inflammation and degree of activity. The prevalence of lymphoid follicles in a single biopsy specimen from antral mucosa was 36%.The dysplasia was seen in 12%; eosinophilia 8%; atrophy 8% and intestinal metaplasia in 6% of the cases.No significant correlation was found between the endoscopic findings and histological findings.Conclusion:Helicobacter pylori infection causes chronic active gastritis and it has a role in the development of lymphoid follicles, intestinal metaplasia, atrophy and dysplasia

ABSTRACT

Background and objectives:Cleft defects are among the most visible congenital defects worldwide and congenital heart disease (CHD)being one of the most common associated anomalies. This study aimed to assess the prevalence of CHD among a cohort of Sudanese patients with cleft lip and/or palate.Patients and Methods:All patients who presented to Soba University Hospital with cleft lip and/or palate from March 2009 toMarch 2015 were included.Results:Out of 381 patients included; 168 patients (44%) had cleft lip and palate (CLP), 156 (41%) had cleft lip (CL)and isolated cleft palate (CP) was found in 57 patients (15%). Facial dysmorphic features were identified in 57 (15%) and cardiac defects in 42 (11%) patients. Ventricular septal defect (VSD) was diagnosed in 16 patients (38%), and ASD in 12 (30.9%). Other macroscopic anomalies were identified in 57 patients (15%)and were associated with CHD (P<0.001). Significant association was found between the type of cleft andCHD (P<0.002), as cardiac defects were maximally observed among CP cases (21%) followed by CLP cases (13%) then CL cases (5.12%). Significant association was also found between facial dysmorphicoccurrence and CHD (P < 0.001).Conclusion:CHD is a common anomaly in cleft population. The pattern of CHD is consistent with the literature withVSD being the most frequent. The cardiac defects are most prevalent in CP group. Echocardiography isjustified for screening of CHD due to the relatively higher incidence of CHD among clefts patients than ingeneral population

ABSTRACT

The aim of this paper was to observe the combination therapy with total triterpenoids of Chaenomeles speciosa and omeprazole on indomethacin-induced gastric ulcer in rats, and explore its possible mechanism. Rats were randomly divided into normal group, model group, omeprazole monotherapy(3.6 mg·kg~(-1)) group, total triterpenoids of C. speciosa monotherapy(100 mg·kg~(-1)) group, total triterpenoids of C. speciosa and omeprazole combination therapy(100 mg·kg~(-1)+3.6 mg·kg~(-1)) group. Except for the normal group, the other groups were given indomethacin(20 mg·kg~(-1)) by oral once a day for 7 consecutive days. Then the treated groups were given corresponding drugs by gavage, once a day for 14 consecutive days. The next day after the last administration, half of the rats in each group were measured the gastric mucosal blood flow, gastric juice volume and serum TNF-α, IL-1β, IL-6, IL-4 and IL-10. After the remaining rats in each group were underwent pyloric ligation 4 hours after the last administration, the gastric endocrine volume, pH value and total acidity of gastric secretion were measured, then histological analysis was performed, MPO activity, cAMP content and histomorphological analysis were conducted. Real-time PCR was applied to detect the mRNA expressions of gastric tissue TNF-α,IL-1β, IL-6, IL-4, IL-10, VEGFA, A_(2A)R; the protein expressions of VEGFA, A_(2A)R, PKA, p-PKA, CREB, p-CREB, EGF, EGFR, p-EGFR, MUC6, TFF2 in gastric tissue were detected by Western blot. The results indicated that total triterpenoids of C. speciosa and omeprazole combination therapy might significantly increase gastric mucosal blood flow, gastric mucus volume, reduce gastric endocrine volume, secretion acidity and mucosal damage, decrease the levels of TNF-α,IL-1β and IL-6, increase the levels of IL-4 and IL-10 in blood and gastric tissue, inhibit the activity of MPO, increase the content of cAMP in gastric tissue, up-regulate the mRNA expressions of VEGFA, A_(2A)R and protein expressions of VEGFA, A_(2A)R, PKA, p-PKA, CREB, p-CREB, EGF, EGFR, p-EGFR, MUC6, TFF2 in gastric tissue, elevate p-PKA/PKA, p-CREB/CREB and p-EFGR/EFGR. Moreover, the combination therapy with total triterpenoids of C. speciosa and omeprazole was more obvious than those of two monotherapies. These aforementioned findings suggested that the combination therapy with total triterpenoids of C. speciosa and omeprazole on indomethacin-induced gastric ulcer have significant therapeutic effect on indomethacin induced gastric ulcer in rats, its mechanism might be related to regulating A_(2A)R/AKT/CREB, A_(2A)R/VEGFA, EGF/EGFR and MUC6/TFF2 signaling pathways, inhibiting pro-inflammatory factors, increasing gastric mucosal blood flow, up-regulating mucosal cell proliferation factors and promoting mucosal protective factors.

ABSTRACT

BACKGROUND/AIMS: Among irritants causing gastric ulcer, Helicobacter pylori (H. pylori) might be pivotal, after which eradication became essential way in either inhibiting ulcerogenesis or preventing ulcer recurrence. Since threonine is essential in either mucus synthesis or cytoprotection, we hypothesized that the dietary threonine from Corynebacterium glutamicum (C. glutamicum) can mitigate the cytotoxicity of H. pylori infection.MATERIALS AND METHODS: RGM-1 cells were challenged with 100 multiplicity of infection H. pylori for 6 hours, during which threonine alone or combination with Corynebacterium sp. was administered and compared for anti-Helicobacter, anti-inflammation, anti-oxidative, and cytoprotective actions.RESULTS: Threonine alone or combination of threonine and C. glutamicum yielded significant bacteriostatic outcomes. The increased expressions of interleukin (IL)-1β, IL-8, Cox-2, and iNOS mRNA after H. pylori infection were significantly decreased with either threonine alone or the combination of threonine and C. glutamicum. The elevated expressions of NF-kB, HIF-1a, and c-jun after H. pylori infection were all significantly decreased with the combination of threonine and broth from C. glutamicum (P < 0.05), leading to significant decreases in 2′,7′-dichlorofluorescein-diacetate (P < 0.01). Tracing further host antioxidative response, the attenuated expression of heme oxygenase-1, Nrf2, and dehydrogenase quinone-1 after H. pylori infection was significantly preserved with combination of threonine and C. glutamicum. H. pylori infection led to significant increases in apoptosis accompanied with Bcl-2 decreases and Bax increases, while the combination of threonine and C. glutamicum significantly attenuated apoptosis, in which attenuated EGF, TGF-β, and VEGF were significantly regulated, while β-catenin did not change.CONCLUSIONS: Threonine synthesized from C. glutamicum significantly alleviated the cytotoxicity of H. pylori in gastric epithelial cells.
