Abstract: The squamous cell carcinoma is more common the malignant epithelial neoplasm of the domestic mammals, even so occurs descriptions in some species of birds. Between the gallinaceous, this tumor is uncommon and the affected animals are in the majority adult and aged. The cutaneous form corresponds most frequent in birds. The squamous cell carcinoma is highly invasive and of changeable malignancy, depending on its localization. The aim of the present study corresponded to the description of a case of dermal squamous cell carcinoma in geriatric rooster. A gallinaceous (Gallus gallus domesticus), male, 10 years of age, was presented with a cutaneous tumor, of gradual growth. The patient was submitted to the physical examination and front to the joined alterations was opted to the surgical debulking of the neoformation. The collected sample was submitted to the histopathological examination. Clinically was evidenced cutaneous tumor, with crusts, inexact limits and tack to adjacent tissues. The same it was located in the distal part of the left hindlimb. The histopathological examination disclosed a compatible morphologic picture with dermal squamous cell carcinoma, moderately differentiated and infiltrate. Three months of after the surgery, signal of return of the neoplasm was observed. KEY WORDS: Cutaneous neoplasm, gallinaceous, squamous cell carcinoma. O carcinoma de células escamosas é a neoplasia epitelial maligna mais comum dos mamíferos domésticos, embora ocorram descri es em várias espécies de aves. Entre os galináceos, esse tumor é incomum e os animais afetados s o na maioria adultos e idosos. A forma cutanea corresponde à mais frequente em aves. O carcinoma de células escamosas é altamente invasivo e de malignidade variável, dependendo da sua localiza o. Em virtude do reduzido número de relatos de neoplasias cutaneas em aves, o presente trabalho objetivou a descri o de um caso de carcinoma dérmico de células escamosas em um galo doméstico geriátrico. Um galináceo (Gallus gallus domesticus), macho, dez anos de idade, foi apresentado com um tumor cutaneo, de crescimento progressivo. O paciente foi submetido ao exame físico e diante das altera es encontradas optou-se pela excis o cirúrgica da neoforma o. Submeteu-se a amostra ao exame histopatológico. Clinicamente, foi constatado um tumor cutaneo ulcerado, com crostas, limites imprecisos e aderência aos tecidos adjacentes, localizado na parte distal do membro pélvico esquerdo. A histopatologia revelou um quadro morfológico compatível com carcinoma dérmico de células escamosas, moderadamente difere

Abstract: El uso empírico de las plantas como agentes de salud es ampliamente conocido en múltiplesculturas del mundo, conocimientos que son transmitidos de generación en generación. En la actualidad, las plantas medicinales y sus extractos, son utilizados con fines terapéuticos, instaurándose como una alternativa farmacológica, para diferentes patologías tanto en humanos como en animales. En la etnomedicina de algunas regiones de Latinoamérica, el paico (Chenopodium ambrosioides) ha sido empleado en infusión de hojas y flores comocarminativo y digestivo, pero principalmente como antihelmíntico. Por lo tanto, el presenteestudio se realizó con el fin de evaluar el efecto antiparasitario del extracto de esta planta engallos de pelea (Gallus domesticus) en un criadero de la ciudad de Tunja-Boyacá, ya que los propietarios de estas aves lo utilizan de manera artesanal como desparasitante natural. Para el trabajo se utilizaron 45 ejemplares, organizados en 3 grupos a los cuales, cada 15días y durante un mes, se les administró, por vía oral, 0,1 ml/ Kg de extracto de paico (grupoT2), 0.5ml/Kg de un medicamento comercial a base de Levamisol-Ivermectina (grupo T3) y0.5ml/ave de agua (grupo T1 control). Se recolectaron muestras de materia fecal con el objeto de determinar la presencia de huevos y/o larvas de parásitos, utilizando la técnica de Formol-Eter. Durante el estudio fueron identificados diferentes especies de ascaridia spp, heterakis gallinarum, eimeria sp, huevos y larvas de trichostrongylus. Posterior a la administracióndel tratamiento con extracto de paico se encontraron huevos de ascaridia galli, heterakis gallinarum, eimeria sp , y al suministrar la última dosis sólo se identificaron huevos de ascaridia galli e eimeria sp , lo que corrobora su efecto antiparasitario. It is widely known empirical use of plants as health workers in many world cultures, knowledgeis transmitted from generation to generation. Currently, medicinal plants and extractsare used for therapeutic drug introduced as an alternative, as treatments for various diseasesin both humans and animals. Ethnomedicine in some regions of Latin America, Paice (Chenopodium ambrosioides) has been used in infusion of leaves and flowers as a carminative and digestive systems, but mainly as an anthelmintic. Therefore, this study was to evaluate the effect paico parasite extract (Chenopodium ambrosioides) in fighting cocks (Gallusdomesticus) in a nursery for the city of Tunja, Boyacá, since the owners of these birds use itthe traditional way as natural de wormer; for work were used 45 fighting cocks, organize

Abstract: The carboxymethylglucan (CMG) is a soluble molecule, composed of glucopyranosyl linked by ?(1-3) e ?(1-6), which can activate the immune system of the host. The purpose of this study was evaluate the productive and immunological characteristics of 192 poultry (Gallus domesticus) COBB line which received feds containing 0%, 0,025%, 0,050% e 0,075% of CMG from Saccharomyces cerevisiae added in corn flour. All poultry were immunized against Newcastle disease and at each treatment 3 poultries randomly chosen received CMG intramuscular at 3, 7 and 14 days. It was evaluated the animal performance, development of the bursa of Fabricius, histological slides of the small intestine, counts of phagocytes cells in blood and levels of antibodies in serum. The results showed difference in weight gain and consumption of feed to poultry that consumed CMG at 1 to 21 days. Fabricius bursa relative weight increased in poultry supplemented with 0,025 e 0,050% of CMG. The phagocytic cells number and total levels of antibodies found in poultry at 21 days were higher in those that received CMG in the diet. For the animals that received intramuscular CMG was observed increase of antibodies specific to Newcastle. A carboximetilglucana (CMG) é uma molécula solúvel, composta de resíduos de glicopiranosil unidos em ?(1-3) e ?(1-6), que possui a capacidade de ativar o sistema imune do hospedeiro. O objetivo do presente estudo foi avaliar as características produtivas e imunológicas de 192 frangos de corte (Gallus domesticus) da linhagem COBB, que receberam ra es contendo 0%, 0,025%, 0,050% e 0,075% de CMG de Saccharomyces cerevisiae adicionada em farinha de milho. Todas as aves foram imunizadas contra a doen a de Newcastle e, em cada tratamento, 3 aves escolhidas aleatoriamente receberam CMG intramuscular no 3o, 7o e 14o dia. Foram avaliados o desempenho animal, o desenvolvimento da bursa de Fabricius e laminas histológicas do intestino delgado, além do número de células fagocíticas no sangue e níveis de anticorpos no soro. Os resultados mostraram diferen a no ganho de peso e consumo de ra o das aves que consumiram a CMG no período de 1 a 21 dias. O peso relativo da bursa de Fabricius aumentou nas aves suplementadas com 0,025 e 0,050% de CMG. O número de células fagocíticas e os níveis de anticorpos totais dos frangos de corte, aos 21 dias de idade foram maiores nas aves que receberam CMG na ra o. Para os animais que receberam CMG via intramuscular foi observado aumento no título dos anticorpos específicos para Newcastle.
