Testes preliminares de motilidade intestinal e toxicidade oral aguda com extrato de cascas pulverizadas de Endopleura uchi (Huber) Cuatrec: (Humiriaceae) em camundongos

The aim of this work was to analyze the acute oral toxicity and the effects on intestinal motility of the extract obtained through decoction 20% (m/v) of Endopleura uchi, popularly known as "uxi-amarelo", a native plant from the Brazilian Amazon. The plant is used indiscriminately against several diseases: arthritis, cholesterol, diabetes, ulcers, myomas, and intestinal illnesses in general, among others. The present results show that there were no significant alterations in intestinal motility and that the extract does not present signs of toxicity, showing its safety for consumption purposes.

Chronic Diseases: Chronic Diseases and Development 2 Health, agricultural, and economic effects of adoption of healthy diet recommendations

Transition to diets that are high in saturated fat and sugar has caused a global public health concern as the pattern of food consumption is a mayor modifiable risk factor for chronic non-communicable diseases Although agri food systems are intimately associated with this transition, agriculture and health sectors are largely disconnected in their priorities policy, and analysis with neither side considering the complex inter relation between agri trade patterns of food consumption health, and development We show the importance of connection of these perspectives through estimation of the effect of adopting a healthy diet on population health, agricultural production trade the economy and livelihoods, with a computable general equilibrium approach on the basis of case studies from the UK and Brazil we suggest that benefits of a healthy diet policy will vary substantially between different populations, not only because of population dietary intake but also because of agricultural production trade and other economic factors

Dermatose responsiva à biotina em cão

Os transtornos da pele e dos pelos são parte importante na prática clínica de pequenos animais. Numerosos fatores nutricionais afetam a homeostase, a qualidade e o aspecto da pelagem. As vitaminas do complexo B incluem compostos hidrossolúveis necessários como coenzimas em diversas funções celulares envolvidas no metabolismo energético e na síntese tecidual. A biotina, em especial, é necessária nas reações de carboxilação, participando da síntese de ácidos graxos, aminoácidos e purinas pelo tecido epitelial. Uma cadela com quadro de cistite recorrente e tumor venéreo transmissível foi tratada com antibioticoterapia prolongada e quimioterapia. Após alguns meses de tratamento, foram observadas lesões no plano nasal e nos coxins plantar e palmar, caracterizadas por hiperceratose, espessamento, fissuras, sangramento e inflamação. O paciente recebeu suplementação de 15mg de biotina por via oral (equivalente a 1,4mg kg-1 de peso corporal), uma vez por dia, durante 60 dias, havendo importante regressão das lesões. Sugere-se que, sob antibioticoterapia e doença, a síntese intestinal de biotina possa não ter sido suficiente, sendo necessária sua suplementação.

Progresso científico sobre nutrição de animais de companhia na primeira década do século XXI

O conhecimento científico sobre nutrição de animais de companhia tem aumentado de forma contínua, acompanhando o fenômeno visto em diversas áreas de conhecimento. Na última década, têm-se prioritariamente pesquisas direcionadas ao uso de nutrientes na promoção de saúde, prevenção de doenças degenerativas, melhoria da qualidade de vida e aumento da expectativa de vida de cães e gatos. Este direcionamento de pesquisas é, em grande parte, explicado pela importância que cães e gatos assumiram na vida das pessoas, fazendo com que as decisões alimentares dos proprietários com seus animais se assemelhassem às que adotam para si próprios. A publicação da nova revisão do Nutrient Requirements of Dogs and Cats em 2006 foi, talvez, o avanço recente mais significativo, trazendo novo entendimento sobre necessidades energéticas e de nutrientes nas diferentes fases de desenvolvimento e estados fisiológicos. Apesar destes avanços, ainda são necessárias pesquisas na área de caracterização físico-química e de utilização dos ingredientes, efeitos do processo de extrusão e mesmo de necessidades nutricionais, que conta com uma base pequena de artigos disponíveis, a maioria antiga. Talvez os desafios científicos mais importantes em nutrição de cães e gatos sejam metabolismo de carboidratos, importância da massa corporal magra na saúde, urolitíases, gerontologia, relação entre microbiota intestinal e saúde, imunonutrição e manejo nutricional em condições clínicas específicas importantes para estas espécies.

Performance and intestinal mucosa development of broiler chickens fed diets containing Saccharomyces cerevisiae cell wall

Use of antibiotics as an additive in poultry diets to improve growth has been discussed in relation to bacterial resistance and the development of new products and management practices. This study was carried out to test the efficacy of a new substance (Saccharomyces cereviside cell walls, var. Calsberg- SCCW) obtained from the brewery industry, added (at 0.1 and 0.2%) to broiler chicken diets (based on corn and soybean meal), on performance and intestinal mucosa development. In Experiment 1 (carried out in litter-floor pens) the results revealed higher body weight gain,for the total experimental period and higher villus height at 7 d of age for the birds fed 0.2%,SCCW. In a field test using 44,000 broilers that,received feed containing 0.2% SCCW,. The results also showed higher body weight gain and better feed conversion for SCCW-supplemented birds. The present findings show that SCCW improved body weight gain in broiler chickens and that this effect can be attributed to the trophic effect of this product on the intestinal mucosa, because it increases villus height, particularly during the first 7. d of a chicken's life.

Morphometry and ultra-structure of the intestinal mucosa of broilers fed different additives

This study aimed at evaluating the effect of the use of different growth promoters on the morphometry and ultra-structure of the intestinal mucosa of 42-day-old broilers. A total number of 36 male Cobb broilers was distributed in a randomized experimental design with a 3 x 3 factorial arrangement, with 3 prebiotic and 3 probiotic sources in the feed, summing up 9 treatments, with 4 replicates each. There was a significant interaction (P<0.01) among the studied factor for villi height (VH) in all intestinal segments, and for crypt depth (CD) in the duodenum and the ileum. In the duodenum, higher villi were obtained in the control group, with the combination of B. subtilis and prebiotics, and with the single use of MOS+OA. No VH differences were observed between the control group and those fed prebiotics. In the jejunum, the highest villi were obtained with the use of the bacterial pool, followed by the control group, and by the use of B. subtilis. Higher villi were also obtained in the control group and in the groups fed MOS, when B. subtilis was used in combination with prebiotics, and when the bacterial pool was used individually or in combination with MOS. In the ileum, the highest villi were obtained with the individual use of B. subtilis, and when MOS+OA or MOS were individually used or in combination with the bacterial pool. As to duodenal CID, deeper crypts were observed in the control group and in those fed B. subtilis or MOS+OA. In the ileum, deeper crypts were also found in the control group and those fed B. subtilis. Deeper crypts were also found when the bacterial pool was individually used or in combination with MOS+OA, and with the individual use of MOS. It was concluded that the use of growth promoters was beneficial to Increase intestinal villi height when Bacillus subtilis was used in combination with prebiotics. The other growth promoters (MOS+OA, MOS, and bacterial pool), can be individually used in most situations. The tested growth promoters did not influence intestinal villi density.
