ABSTRACT

Aedes aegypti is the vector of several viral diseases. The main way to control these diseases is to fight the vector. Thus, it is necessary to breed mosquitoes in the laboratory in order to develop strategies to control these insects. In laboratories, different carbohydrates are used for feeding mosquitoes. The aim of this study is to evaluate the longevity and the weight of Ae. aegypti fed with different carbohydrates diets. As methods, 120 mosquitoes were distributed in insectaries and each group received a different diet, based on honey, dextrose or maltodextrin. To assess the longevity, survival analysis was performed using the Long Rank test and chi square test. To assess the weight, the dead insects were frozen and weighed at the end of the experiment. As results it was observed that mosquitoes fed with the honey, maltodextrin and dextrose diet lived on average 33, 35 and 47 days respectively. When weight was assessed, mosquitoes fed with honey weighed 125 ± (35.3) µg, while those fed with dextrose and maltodextrin weighed 225 ± (35.3) µg and 275 ± (35.3) µg respectively. The results show that the intake of dextrose and maltodextrin by Ae. aegypti adults increases their survival and their weight.(AU)


O Aedes aegypti é vetor de várias doenças virais. A principal maneira de controlar essas doenças é combatendo o seu vetor. Nesse sentido, é necessário criar esses mosquitos em laboratório, visando desenvolver estratégias de controle. Nos laboratórios, diferentes carboidratos são utilizados na alimentação de mosquitos. O objetivo deste estudo é avaliar longevidade e peso de Ae. aegypti alimentados com diferentes fontes de carboidratos. Como método, distribuíram-se 120 mosquitos insetários. Cada grupo recebeu uma dieta diferente à base de mel, dextrose ou maltodextrina. Para avaliar a longevidade, a análise de sobrevida foi realizada pelo teste de Logrank e pelo teste de qui quadrado. Para avaliar o peso, os insetos mortos foram congelados e pesados ​​no final do experimento. Como resultado, observou-se que os mosquitos alimentados com a dieta à base de mel, maltodextrina e dextrose viveram em média 33, 35 e 47 dias, respectivamente. Com relação ao peso, os mosquitos alimentados com mel pesavam 125 ± (35,3)µg, enquanto os alimentados com dextrose e maltodextrina pesavam 225 ± (35,3)µg e 275 ± (35,3)µg, respectivamente. Os resultados mostram que a ingestão de dieta à base de dextrose e maltodextrina por Ae. aegypti adultos aumenta sua sobrevivência e seu peso.(AU)

ABSTRACT

O mel de abelha é um produto de consumo relevante pela população devido aos seus fatores nutricionais e terapêuticos. A adulteração é um exemplo de como as características do mel podem ser afetadas, prejudicando os consumidores que desejam comprar produtos puros e de alta qualidade. Este trabalho teve como objetivo avaliar a qualidade físico-química do mel de abelha comercializado em Brasília, Distrito Federal. Foram obtidas 13 amostras de mel de abelhas: uma de um apicultor da região com certificação de produção (usada como controle negativo), seis de lojas de produtos naturais e hipermercados no centro de Brasília e seis de feira livre e pequenos estabelecimentos de uma região administrativa do Distrito Federal, das quais cinco não tinham o selo do Serviço de Inspeção Federal (SIF) na embalagem. Também foi usada uma amostra comercial de xarope de glicose como controle positivo. Para verificar a adulteração, foram adotados os testes de Lund, Fiehe e Lugol, bem como as análises de pH, acidez titulável e umidade, para serem comparados com os parâmetros de qualidade do mel estabelecidos pela legislação vigente. As análises verificaram a qualidade dos méis comercializados com o selo SIF, com algumas ressalvas para a possível alteração de temperatura. Já as que não possuíam selo, apenas uma foi aprovada nos testes de qualidade, porém sua venda não é regularizada. A maioria das amostras analisadas apresentaram resultados consistentes com os padrões exigidos pela legislação vigente, com maiores irregularidades na comercialização de méis em feira livre, mostrando a necessidade de maior controle de qualidade e inspeção de produtos não certificados.(AU)


Bee honey is a product of relevant consumption by the population due to its nutritional and therapeutic factors. Tampering is an example of how honey characteristics can be affected and harming consumers who want to buy a high quality and pure product. This work aimed to evaluate the physicochemical quality of bee honey commercialized in Brasília, Federal District. Thirteen samples of bee honey were obtained: one from a certified local beekeeper (used as a negative control), six from natural products and hypermarkets in central Brasília and six from street fair and small establishments in one of the administrative region of the Federal District, of which five did not have the seal of the Federal Inspection Service (SIF) on the packaging. Also, a sample of commercial glucose syrup was used as positive control. To verify tampering, the Lund, Fiehe and Lugol tests were adopted, as well as the pH, titratable acidity and humidity analysis, to be compared honey quality parameters established by the current legislation. The analyzes verified the quality of the honeys sold with SIF seal, with some restraints for the possible temperature changes. As for those that did not have a seal, only one passed the quality tests, but its sale is not regularized. Most of the samples analyzed showed results consistent with the standards requirements of the current legislation, with greater irregularities in the marketing of honey in street fair, showing the need for greater quality control and inspection of non-certified products.(AU)

ABSTRACT

SUMMARY: The treatment of chronic wounds has become a public health issue in recent years mainly due to comorbidities associated with an older population and bacterial resistance. Honey has emerged as an alternative treatment for chronic wounds but lack of knowledge of its mechanism of actionin the treated tissue and low quality of evidence in clinical triads has distanced the medical community from honey as a possible treatment. One of the main processes that is altered in chronic wounds is re-epithelialization mediated by keratinocytes, where proliferation and migration processes are altered. Markers of proliferation, migration and activation of keratinocytes, such as adhesion molecules, growth factors, membrane receptors, signal translating proteins, transcription factors, microRNAs, among others are deregulated in this process. In general, honeys from different floral origins have a positive effect on markers of proliferation and migration in keratinocytes. In conclusion there are still few studies that focus on the molecular action of honey in keratinocytes and fail to report details on the honey used not allowing to achieve the same results.


RESUMEN: El tratamiento de heridas crónicas (HC) se ha vuelto un tema de salud pública en los últimos años, principalmente debido a comorbilidades asociadas a una población de mayor edad y a la resistencia bacteriana. La miel ha surgido como un tratamiento alternativo para HC pero la falta de conocimiento de su mecanismo de acción en el tejido tratado y de la baja calidad de la evidencia en triadas clínicas, ha distanciado a la comunidad médica de la miel como posible tratamiento. Uno de los principales procesos que se ve alterado en las HC es la re-epitelización mediada por queratinocitos, donde se ven alterados los procesos de proliferación y migración. Marcadores de proliferación, migración y activación de queratinocitos, como moléculas de adhesión, factores de crecimiento, receptores de membrana, proteínas traductores de señales, factores de transcripción, microARNs, entre otras, se ven desreguladas en éste proceso. De manera general las mieles de diferentes orígenes florales tienen un efecto positivo en marcadores de proliferación y migración en queratinocitos. En conclusión aún existen pocos estudios que se enfoquen en la acción molecular de la miel en queratinocitos y los pocos que existen fallan en la entrega de información en relación a la miel utilizada que pueda hacer reproducibles los resultados.

ABSTRACT

Cicatrização de ferida é um processo dinâmico, que tem por objetivo restaurar a continuidade do tecido lesionado. No entanto, em alguns casos, é necessário favorecer condições adequadas para viabilizar o processo fisiológico. Neste estudo foram utilizados ratos Wistar, divididos aleatoriamente entre cinco grupos, com 12 animais cada, sendo eles: grupo P (Bidens pilosa L.), grupo mel, grupo Co1 (pomada comercial alopática), grupo Co2 (pomada comercial homeopática) e grupo CT (controle). As lesões foram geradas por incisão com punch de 8mm, sendo tratadas diariamente de forma tópica. Foram eutanasiados quatro animais por grupo, no terceiro, sétimo e 14º dias do experimento, e o material coletado foi armazenado em formalina 10% e encaminhado para processamento histológico. Posteriormente, realizou-se a contagem de leucócitos mononucleares, fibroblastos e neovasos e avaliou-se a arquitetura de fibras colágenas. Os resultados da contagem foram analisados pela ANOVA, seguida pelo teste de Tukey (P<0,05). O modelo experimental proposto neste estudo demonstrou que todos os tratamentos apresentaram potencial cicatrizante, com exceção do mel. A aplicação tópica do creme do extrato de Bidens pilosa L. a 10% apresentou melhor perfil anti-inflamatório; a pomada alopática apresentou boa aderência à superfície da lesão e a pomada homeopática, grande potencial angiogênico, com menor tempo de cicatrização.(AU)


Wound healing is a dynamic process that aims to restore the continuity of injured tissue. However, in some cases it is necessary to favor adequate conditions to enable the physiological process. Wistar rats were randomly divided into 5 groups with 12 animals each, namely: group P (Bidens pilosa L.), group honey, group Co1 (commercial allopathic ointment), group Co2 (commercial homeopathic ointment) and group CT (control). The lesions were generated by an 8mm punch incision and were treated topically daily. Four animals per group were euthanized on the 3rd, 7th and 14th day of the experiment and the collected material was stored in 10% formalin and sent for histological processing, after which mononuclear, fibroblasts and neovascular leukocytes were counted and collagen fiber architecture was evaluated. Counting results were analyzed by ANOVA, followed by Tukey test (p <0.05). The experimental model proposed in this study showed that all treatments had healing potential, except honey. The topical application of 10% Bidens pilosa L. extract cream showed the best anti-inflammatory profile; Allopathic ointment showed good adhesion to the surface of the lesion and homeopathic ointment showed great angiogenic potential with shorter healing time.(AU)

ABSTRACT

Honey is a natural antioxidant that its protective effects have been proven against ischemia-reperfusion (IR) injury. The aim of this study was to evaluate the ameliorative effect of Persian Honey, Apis mellifera meda skorikov, on gastrocnemius muscle IR injury. Eighty adult male Sprague-Dawley rats weighing 250-300 g were used. They were divided into ten groups (N=8 per group). The ischemia was conducted with a silk suture 6-0 using the slipknot technique. All groups were rendered in ischemic for 3 h, and reperfused for various times of 3 days (3-day reperfusion), 7 days (7-day reperfusion), 14 days (14-day reperfusion), and 28 days (28-day reperfusion). Half of the groups had experimental honey (5 %) treatment immediately after ischemia. After reperfusion, the rats, based on the grouping, were killed with high doses of anesthetic, and the gastrocnemius muscles were removed and fixed. After the tissue processing, the evaluation of edema and mast cells infiltration was performed with hematoxylin-eosin and toluidine blue staining, respectively. TNF-α was detected with immunohistochemistry method. The amount of TNF-α as an index of acute inflammatory except the 3rd day significantly decreased on the other day of reperfusion (7th, 147th and 287th days). The mast cells infiltration was significantly decreased on 77th and 147th days. The tissue edema was decreased significantly in honey administrated group in the comparison with placebo groups. Honey administration can reduce damage caused by ischemia-reperfusion in the rat gastrocnemius muscle.


La miel es un antioxidante natural; sus efectos protectores han sido probados contra la lesión por isquemiareperfusión (IR). El objetivo de este estudio fue evaluar el efecto de mejora de la miel persa Apis mellifera meda skorikov, en la lesión por IR del músculo gastrocnemio. Se utilizaron 80 ratas Sprague-Dawley macho adultas con un peso entre 250 y 300 g divididas en diez grupos (N = 8 por grupo). La isquemia se realizó con una sutura de seda 6-0 utilizando la técnica slipknot permaneciendo isquémicos durante 3 h. La reperfusión se realizó durante varios tiempos de 3 días, 7 días (reperfusión de 7 días), 14 días (reperfusión de 14 días) y 28 días (28 días reperfusión). La mitad de los grupos recibió tratamiento experimental con miel (5 %) inmediatamente después de la isquemia. Después de la reperfusión, las ratas, fueron sacrificadas con altas dosis de anestésico, y los músculos gastrocnemios fueron removidos y fijados. Después de procesar el tejido, se realizó la evaluación del edema y la infiltración de mastocitos se realizó con tinción de hematoxilina-eosina y azul de toluidina, respectivamente. TNF-α se detectó con el método de inmunohistoquímica. La cantidad de TNF-α como índice de inflamación inflamatoria aguda, excepto en el tercer día, disminuyó significativamente al día siguiente de la reperfusión (7, 14 y 28 días). La infiltración de mastocitos disminuyó significativamente a los 7 y 14 días. El edema tisular disminuyó significativamente en el grupo administrado con miel en comparación con los grupos placebo. El tratamiento con miel puede reducir el daño causado por la isquemia-reperfusión en el músculo gastrocnemio de la rata.

ABSTRACT

Para promover la reparación y regeneración muscular, se han desarrollado diferentes estrategias, sin embargo, aún no existe un tratamiento único aceptado. Investigaciones relacionan los efectos terapéuticos de la miel en el proceso de cicatrización de heridas de diversas etiologías. Considerando lo anterior, el propósito de este estudio fue evaluar los efectos de una formulación basada en miel nativa (Ulmoplus®) en la reparación de lesiones musculares por incisión quirúrgica. A cinco conejos (Oryctolagus cuniculus) se les realizó una incisión de 20 mm de largo y 3 mm de ancho en la región anterior de cada pierna, atravesando la epidermis, dermis y el músculo tibial anterior, hasta alcanzar el periostio de la tibia. La pierna izquierda de cada animal fue clasificada como grupo sutura (S) y la derecha como grupo sutura más Ulmoplus® (S+U). Posteriormente, al grupo S+U se le aplicó Ulmoplus® en toda la extensión de la herida. Luego, en ambos grupos, la incisión fue suturada con cuatro puntos intradérmicos (vicryl 2/0). Un animal fue considerado como control para obtener imágenes histológicas del músculo tibial anterior sin injuria. A los 10 días post incisión, fueron tomadas las biopsias del músculo y posteriormente fueron procesadas para su observación en microscopio de luz. El estudio se llevó a cabo considerando las recomendaciones de la Guía para el Cuidado y Uso de Animales de Laboratorio. A los 10 días post incisión, las injurias, en ambos grupos de animales, se encontraban cerradas y sin signos de infección. El músculo tibial anterior de los especímenes del grupo S se encontraba en la fase de reparación, con procesos concomitantes de fagocitosis del tejido necrotizado, regeneración de miofibras y formación de tejido conectivo cicatrizal. El músculo tibial anterior de los animales del grupo S+U se encontraba en la fase de remodelación, ya que la arquitectura muscular se evidenciaba restablecida. Ulmoplus®, como coadyuvante en el proceso de cierre de heridas quirúrgicas de músculo esquelético utilizando sutura convencional, es una buena alternativa, ya que acelera el proceso de reparación muscular, y reduce el tejido conectivo cicatrizal.


To promote muscle repair and regeneration, different strategies have been developed, however, there is still no single accepted treatment. Research relates the therapeutic effects of honey in the wound healing process of various etiologies. The aim of this study was to evaluate the effects of native honey formulation (Ulmoplus®) in the repair of muscle injuries by surgical incision. In five rabbits (Oryctolagus cuniculus) were made an incision 20 mm long and 3 mm wide in the anterior region of each leg, crossing the epidermis, dermis and anterior tibial muscle, until reaching the tibia periosteum. The left leg of each animal was classified as a suture group (S) and the right leg as a suture group plus Ulmoplus® (S + U). Subsequently, Ulmoplus® was applied to the entire S + U group throughout the entire length of the wound. Then, in both groups, the incision was sutured with four intradermal points (vicryl 2/0). An animal was considered as a control to obtain histological images of the anterior tibial muscle without injury. At 10 days post incision, muscle biopsies were taken and subsequently processed for observation under light microscopy. The study was carried out considering the recommendations of the Guide for the Care and Use of Laboratory Animals. At 10 days post incision, the injuries, in both groups of animals, were closed and without signs of infection. The anterior tibial muscle of the S group specimens was in the repair phase, with concomitant processes of phagocytosis of the necrotized tissue, myofiber regeneration and formation of scar connective tissue. The anterior tibial muscle of the animals of the S + U group was in the remodeling phase, since the muscular architecture was evidenced restored. Ulmoplus®, as an adjunct in the process of closing surgical wounds of skeletal muscle using conventional suture, is a good alternative, since it accelerates the muscle repair process and reduces scar connective tissue.

ABSTRACT

The objective of this research was to estimate the correlations between the biometric and reproductive parameters of Melipona scutelaris. Four collections were performed with 30-day intervals, consisting of the evaluation of each colony, considering the following parameters: honey pot size and volume (HPS and VHP), estimated honey production (EHP), number of combs (NC), mean diameter of the combs (MDC), height of the combs (HC), height of rearing cells (HRC), number of pups (NP) population (POP) and wax envelope in pups. The data were analyzed using the SAS software (2004), and the Pearson correlation coefficient was used for the correlation calculations. The correlations of the studied variables of production and biometrics of Melipona scutellaris colonies made it possible to perceive that the variable number of honey pots (NHP) present a higher correlation with HPS, EPH, DMC, HRC, NP and POP, followed by size of pots of honey (HPS) with: VHP, EHP, MDC, HC and POP. For future studies using the productive and biometric characteristics of the bees Melipona scutellaris can be considered for EPH, VHP, EPH, NC and POP, as variable responses.(AU)

ABSTRACT

Licorice is one of the most commonly used traditional Chinese medicine. In clinic, raw licorice and honey-fried licorice are used in medicines, with the main effects in clearing away heat and detoxifying, moistening lungs and removing phlegm. Honey-fried licorice has effects in nourishing the spleen and stomach and replenishing Qi and pulse. Because traditional Chinese medicine exerts the effects through multiple components and multiple targets, the index components used in the quality evaluation of licorice are often difficult to reflect their real quality. In addition, most of studies for the quality standards have shown that honey-fried licorice are the same as licorice, with a lack of quality evaluation standards that can demonstrate their processing characteristics. The quality of medicine is directly related to its clinical efficacy, so it is necessary to establish a more effective quality control method. Licorice has a beany smell, which is one of the main quality identification characteristics. In this study, by taking advantage of the odor characteristics, a headspace-gas chromatography-ion migration mass spectrometry technology was used to establish a quality evaluation method. A total of 76 volatile components were identified. Through the dynamic principal component analysis, 7 kinds of volatile substances in raw licorice and 13 kinds of volatile substances in honey-fried licorice were statistically obtained, and could be taken as index components for the quality evaluation of raw and honey-fried licorice, respectively. This study could help realize the combination and unification of modern detection and traditional quality evaluation methods, and make a more realistic evaluation for the quality of licorice.

ABSTRACT

Licorice has long been regarded as one of the most popular herbs, with a very wide clinical application range. Whether being used alone or as an ingredient in prescription, it has an important role which cannot be ignored. However, the efficacy and chemical constituents of licorice will change after honey-processing. Therefore, it is necessary to find quality markers before and after honey-processing to lay the foundation for a comprehensive evaluation of the differences between raw and processed licorice pieces. HPLC-DAD was employed to establish fingerprints of raw and processed licorice. Multivariate statistical analysis methods including principal component analysis(PCA) and orthogonal partial least squares discrimination analysis(OPLS-DA) were applied to screen out the differential components before and after processing of licorice. Based on network pharmacology, the targets and pathways corresponding to the differential components were analyzed with databases such as Swiss Target Prediction and Metascape, and the "component-target-pathway" diagram was constructed with Cytoscape 3.6.0 software to predict the potential quality markers. A total of 17 common peaks were successfully identified in the established fingerprint, and seven differential components were selected as potential quality markers(licoricesaponin G2, glycyrrhizic acid, liquiritigenin, liquiritin, isoliquiritin, liquiritin apioside and isoliquiritigenin). The HPLC fingerprint method proposed in this study was efficient and feasible. The above seven differential chemical components screened out as potential quality markers of licorice can help to improve and promote the overall quality. These researches offer more sufficient theoretical basis for scientific application of licorice and its corresponding products.

ABSTRACT

Abstract Monofloral honeys are high-added-value food, a reason for constant cases of fraud. This study investigated Brazilian monofloral honeys from Hovenia dulcis flowering produced by Apis mellifera and Tetragonisca angustula bees. Chemical, physicochemical, rheological, and melissopalynological analysis were assessed. Properties such as moisture, pH, ashes, total acidity, total available carbohydrate, and soluble sugars of all analyzed honey samples agreed with the established by the legislation. All the honey samples were satisfactorily fitted by both Ostwald-de Waele and Casson rheological models revealing homogenous products, mostly presenting pseudoplastic character. The melissopalynology confirmed the presence of H. dulcis pollen in the MH samples; however, some honeys did not show >45% pollen of H. dulcis, thus revealing mislabeling cases. Continuous evaluation of honey is necessary, once this is a valuable food frequently involved in frauds, hence causing problems to consumers.

In general, there are significant differences between the physicochemical characteristics of floral honeys and honeydew honey. OBJECTIVE: to determine the percentage of flower honey and honeydew honey sold in supermarkets in the City of La Paz. METHODS: for the differentiation between flower honey and honeydew honey, the standardized method by the Beekeeping Research Center - CEDIA) was used and for the determination of the physicochemical parameters, the methods established in the Bolivian Standard (NB 38023). RESULTS: 25 samples of honey sold in supermarkets in the city of La Paz were analyzed, and through the qualitative parameter of differentiation of flower honey and honeydew honey, it was possible to show that 88.46% corresponds to honeys of origin floral, 7.69% to honeydew honeys and 0.96 to adulterated honeys. CONCLUSIONS: the data obtained reflect the importance of considering the origin of the honey in the labeling, as well as recommending that this parameter be part of the requirements of the Bolivian Honey Standard and thus granting a greater commercial value to the honey of national origin.

ABSTRACT

Introducción: las úlceras en miembros inferiores hacen parte de las enfermedades crónicas que afectan a la población mundial, las cuales generan deterioro en la calidad de vida de quienes las padecen. La miel es un alimento natural utili-zado a lo largo de la historia de la humanidad con fines curativos para el manejo de las lesiones en la piel; sin embargo, el beneficio de su uso en el tratamiento de las úlceras de miembros inferiores no ha sido definido, ya que la evidencia actual es controversial. Objetivo: evaluar la mejor evidencia científica disponible para determinar los beneficios de la miel en el tratamiento de las úlceras crónicas de miembros inferiores en la población adulta. Metodología: se realizó una revisión sistemática de la literatura de ensayos clínicos controlados, aleatorizados en las bases de datos PubMed, Ovid, ProQuest, EBSCO, BIREME. Se incluyeron 9 ensayos clínicos controlados. Se evaluó la calidad metodológica según los parámetros de PeDro y se utilizaron criterios de la colaboración Cochrane para definir la presencia de sesgos de cada estudio. Resultados: ocho de los 9 estudios incluidos reportaron desenlaces favorables en el uso de la miel. Los estudios conta- ron con buena calidad metodológica en su desarrollo, pero evidenciaron un riesgo poco claro de sesgo. Conclusión: la evidencia disponible no permite establecer la utilidad de la miel en el manejo de las úlceras de miembros inferiores. La evidencia actual muestra poca claridad en términos de sesgos, por lo que es necesario realizar nuevos ensayos clínicos, con mejores criterios de intervención, para poder establecer el beneficio del uso de la miel en esta enfermedad


Background: Leg ulcer are part of chronic diseases that affect word population, generating a big burden in quality of life. Honey is a natural food used along humanity history as a topic medicine for skin conditions. The benefits of using honey as a treatment of chronic leg ulcers has not been clarified because off controversial evidence. Objectives: This review assess the best scientific evidence to establish the benefits of using honey in chronic leg ulcers in adult population. Methods: A systematic Review of randomized clinical trials was made in PubMed, Ovid, ProQuest, EBSCO and BIREME databases. 9 controlled clinical trials were included. Methodological quality was assessed using PeDro criteria. Risk of bias was assessed using Cochrane parameters. Results: Eight of nine clinical trials included reported beneficial outcomes using honey in chronical leg ulcers treatment. Trials were made with good methodological quality however their had unclear risk of bias. Conclusion: Available evidence does not let define the usefulness of applying honey in chronic leg ulcers. Data is unclear in terms of bias; thus, it is necessary to perform new randomized clinical trials with better intervention criteria to define if using topical honey in chronic leg ulcers is beneficial or not compared with conventional treatment

ABSTRACT

La mucositis es una respuesta inflamatoria del epitelio de la mucosa a los efectos citotóxicos de la quimioterapia y la radioterapia, que causan dolor y ulceración oral severa. En los estudios de los últimos años se ha propuesto el uso de la miel en el manejo de la mucositis oral inducida por quimioterapia y radioterapia en pacientes pediátricos. La miel reduce la severidad y duración de la mucositis, reduce el dolor y es un producto agradable a los niños. Por tanto, podría ser un producto eficaz tanto en la profilaxis como en el tratamiento de la mucositis oral. Sin embargo, la pequeña cantidad de investigaciones realizadas en humanos no es suficiente para establecer recomendaciones generalizadas. Por ello, se debe aumentar las investigaciones en este campo. Con ello se podrá examinar la eficacia y posibles complicaciones a corto y largo plazo, explorar su posible efecto sinérgico con otras terapias, analizar su rentabilidad económica y el tipo de miel más adecuado. De esta forma, los profesionales sanitarios podrán ofrecer a los pacientes pediátricos los mejores cuidados basados en las últimas evidencias científicas demostradas.


Mucositis is an inflammatory response of the mucosal epithelium to the cytotoxic effects of chemotherapy and radiation therapy, causing pain and severe oral ulceration. In the studies of recent years, the use of honey has been proposed in the management of oral mucositis induced by chemotherapy and radiotherapy in pediatric patients. Honey reduces the severity and duration of mucositis, reduces pain and is a child-friendly product. Therefore, it could be an effective product both in the prophylaxis and in the treatment of oral mucositis. However, the small amount of human research is not enough to establish widespread recommendations. Therefore, research in this field should be increased. With this, it will be possible to examine the efficacy and possible complications in the short and long term, explore its possible synergistic effect with other therapies, analyze its economic profitability and the most appropriate type of honey. In this way, healthcare professionals will be able to offer pediatric patients the best care based on the latest scientific evidence.

ABSTRACT

Considerando los avances en las investigaciones que relacionan los efectos terapéuticos de la miel en el proceso de cicatrización de heridas, la presente investigación tuvo como objetivo evaluar y comparar cualitativamente, a través de una análisis morfológico, la respuesta tisular local entre sutura convencional coadyuvada con Ulmoplus® y sin Ulmoplus® en el cierre de la incisión de piel de conejo. Se utilizaron 10 conejos adultos, divididos en grupo S (sutura) y grupo S+U (sutura más Ulmoplus®). Se les realizó una incisión de 10 mm de largo, en la región anterior de la pierna, a través de la epidermis y dermis, hasta llegar a la fascia profunda que cubría al músculo tibial anterior. Posteriormente, solo al grupo S+U se le aplicó Ulmoplus®. Luego, en ambos grupos, la incisión fue suturada con dos puntos intradérmicos de ácido poliglicólico (vicryl 2/0). Después de 10 días post incisión fueron tomadas las biopsias de la piel y procesadas para su observación en microscopio de luz. El estudio se llevó a cabo considerando las recomendaciones de la Guía para el Cuidado y Uso de Animales de Laboratorio. Ambos grupos presentaron una incisión cerrada al día 10, con características microscópicas propias de una fase proliferativa. No obstante, el grupo S+U mostró una cicatriz de menor longitud y de aspecto más plano, cuya epidermis estaba mejor organizada y era de menor grosor, con células basales diferenciadas. A nivel dérmico se observó contracción de la herida, evidenciándose una zona cicatrizal de menor tamaño. Ulmoplus®, es una buena alternativa como coadyuvante en el proceso de cierre de heridas quirúrgicas utilizando sutura convencional, ya que acelera el proceso de cicatrización y permite mejores resultados estéticos de la cicatriz.


Considering the advances in research that relate honey therapeutic effects in wound healing process, the present investigation aimed to evaluate and compare qualitatively, through morphological analysis, the local tissue response between conventional suture with Ulmoplus ® and without Ulmoplus ® in the closure of the rabbit skin incision. We used 10 adult rabbits, divided into group S (suture) and group S + U (suture plus Ulmoplus®). An 10 mm long incision was made in the anterior region of the leg, passing through epidermis and dermis, until reaching the deep fascia that covered the anterior tibial muscle. Subsequently, only the S + U group was given Ulmoplus®. Then, in both groups, the incision was sutured with two intradermal points of polyglycolic acid (vicryl 2/0). After 10 days post incision, biopsies of the skin were taken and processed for observation in a light microscope. The study was carried out considering the recommendations of the Guide for the Care and Use of Laboratory Animals. Both groups had a closed incision at day 10 with microscopic characteristics of a proliferative phase. However, the S + U group showed a scar of shorter length and flatter appearance, whose epidermis was more organized and thinner, with differentiated basal cells. At the dermal level, wound contraction was observed, evidencing a smaller scar area. Ulmoplus®, as a coadjuvant in closing surgical wounds process using conventional suture is a good alternative, since it accelerates the healing process and allows better aesthetic results of the scar.

ABSTRACT

Resumo A integração entre os níveis de atenção é um desafio contínuo mesmo em sistemas de saúde consolidados e de alta performance. A reestruturação do sistema público de saúde do Distrito Federal, baseado no fortalecimento da Atenção Primária à Saúde (APS), na reconfiguração da atenção especializada (ambulatorial e hospitalar) e de sua rede de urgência e emergência, trouxe como desafio a necessidade de integração entre esses níveis. Fez-se necessária a criação de um dispositivo que desempenhasse o papel de "gatekeeper" conduzindo o acesso equânime, transparente e seguro para a atenção especializada e hospitalar. Neste sentido, foi estruturado o Complexo Regulador em Saúde do Distrito Federal (CRDF) e suas Centrais de Regulação (CR), orientados para a execução de um processo regulatório de acesso para os serviços de internação hospitalar, ambulatorial (procedimentos e consultas especializadas), cirurgias eletivas, alta complexidade, transporte sanitário, urgências e transplantes de pacientes do Distrito Federal e de fora dele. Este artigo descreve o processo de implantação e de implementação do CRDF e de suas CR, de forma a refletir sobre as potencialidades e desafios de seu papel enquanto instrumento de integração entre os níveis assistenciais de saúde.


Abstract The integration among levels of care is a continuous challenge even in consolidated and high performance health systems. The reform of public health system of Distrito Federal, based on the strengthening of primary health care associated to the reconfiguration of specialized attention (ambulatory and hospital) and of its of urgency and emergence network brought, as a challenge, the need for integration between these levels. Thus, became necessary to create an instrumentto perform the role of gatekeeper, leading to equanimous, transparent and safe access to specialized and hospital care. Thus, the Regulatory Complex in Health of Distrito Federal (CRDF) and its Regulatory Centers (CR) were created to carry out the regulatory process of access to care services, such as hospitalization, ambulatory care (procedures and specialized consultations), elective surgeries, complex procedures, sanitary transport, urgencies and transplants of patients of the Federal District and outside it. This article describes the process of the CRDF implementation and its CRs, aiming to reflect on the potential and challenges of its role as an instrument of integration among the levels of care.

ABSTRACT

Natural medicinal systems such as Ayurveda and folk medicine has remedies for wound management. However, the exact cellular and extracellular mechanisms involved in the healing process and its influence on keratinocytes is less discussed. Therefore, the present study was designed to evaluate the effect of certain natural wound healing medicines on the biology of the keratinocytes/HaCaT cells. Test materials such as honey (H), ghee (G), aqueous extracts of roots of Glycyrrhiza glabra (GG) and leaves of Nerium indicum (NI) were considered. The HaCaT cells were treated with the test materials singly and in combinations (H+G, all combined [Tot]) for a specific period (24, 48, and 72 hours). The cells were then subjected to cytotoxicity/proliferation and migration/scratch assays. All the test materials, except NI, were non-cytotoxic and showed increased cell proliferation at variable concentrations. Significant observations were made in the groups treated with honey (100 µg/ml at 48 hours, P<0.05; 1,000 µg/ml at 72 hours, P<0.05), GG (all concentrations at 48 hours, P<0.05; 750 µg/ml at 72 hours, P<0.05), H+G (250 µg/ml at 24 hours, P<0.001; 500 µg/ml at 48 and 72 hours, P<0.05), and Tot (50 µg/ml at 24, 48 and 72 hours, P<0.01). In the in-vitro wound healing assay, all the treated groups showed significant migration and narrowing of the scratch area by 24 and 48 hours (P<0.001) compared to control. The results obtained from the present study signifies the positive influence of these natural wound healing compounds on keratinocytes/HaCaT cells.

ABSTRACT

Abstract Many different types of honey are available in the Brazilian market. They vary in color, flavor, smell, thereby increasing interest in honey characterization relating to botanical origin. A total of 155 honey samples belonging to Brazilian flora were examined on the pollen analysis; sampling is made in a span of one year. The preparation followed melisso palynological analysis based on the specific botanical variety. The pollen spectra revealed 60 pollen types belonging to 27 plant families and Myrtaceae, Fabaceae and Asteraceae were the dominant plant families. Few pollen types were found in most samples of honey. The families that showed major richness of pollen types were Fabaceae and Asteraceae. Only six floral sources of pollen plants and three floral sources of nectar plants appeared in the category of predominant pollen. The unifloral honeys were slightly more frequent than polyfloral, and wild floral species dominated most of the honey samples. These floral sources, even in minor parts in the honeys samples, are also part of the biological feature of theses honeys. The honeys from natural fields cannot be completely accounted by the term unifloral honeys.
