Four equidistant wounds were induced in the dorsal skin of 20 adult male rabbits, which were submitted to healing by secondary intention and treated with 5% chitosan cream (QC, n=5), 5% barbatiman cream (BC, n=5), 2% allantoin cream (n=5), and base cream (n=5). The creams were applied with the aid of disposable spatulas after washing the wounds. The wounds were daily analyzed by clinical examination for 21 days and histological analyses were performed on the 3 rd , 14 th , and 21 st day after induction. The microscopic evaluation of the wounds of all groups showed macroscopic features of the healing process at different time intervals. The QC and BC treatments helped in the skin repair process in rabbits when compared to the other two treatments. They induced fibroblast activation and early collagen deposition, and modulated re-epithelialization and neovascularization. Thus, it was concluded that BC and QC are efficient and economically feasible as adjuvants in the healing process of skin wounds in rabbits.

As afecções podais em bovinos também ocasionam prejuízos relacionados a gastos com tratamento medicamentoso e cirúrgico, redução da fertilidade e descarte precoce de animais. A estrutura e a qualidade do casco dependem de um adequado processo de queratinização, que é influenciado pelo satisfatório suprimento de nutrientes como aminoácidos, lipídios, vitaminas e minerais. A deficiência de nutrientes importantes para a formação do estojo córneo promove síntese de tecido queratinizado de baixa qualidade e com maior suscetibilidade a danos químicos, físicos e microbianos. Dessa forma, a nutrição é importante para a formação de um estojo córneo resistente e, também, para a redução da incidência de doenças digitais em bovinos. Diante disso, objetivou-se com o presente artigo fazer uma revisão sobre a ...

Em alguns casos, pode-se diagnosticar severo comprometimento da mucosa do folheto prepucial interno o que pode inviabilizar a cirurgia. Dentre as complicações, quando se opta pelo ato operatório, o comprometimento da extremidade livre do pênis não tem sido apontado como sequela frequente. Este trabalho objetiva descrever os achados clínicos e histopatológicos, de um caso incomum de estenose e fibrose do folheto prepucial interno com consequente necrose da extremidade livre do pênis, como intercorrência após a cirurgia de acropostite-fimose. Durante o procedimento foram colhidos fragmentos das áreas lesionadas para exame histopatológico. Não foi possível efetuar a correção cirúrgica da fimose prepucial, sendo a amputação de um segmento peniano necessária. O procedimento foi respaldado pelos achados histopatológicos, confirmando a gravidade do caso. O laudo histopatológico revelou glande com áreas focalmente extensas e superficiais de necrose, dentre outros achados. PALAVRAS-CHAVE: Bovinos, genitália externa, impotência coeundi, reprodutores.
