Avaliação nutricional do feno das folhas da amoreira (Morus alba L.) em frangos de corte

The trial was carried to evaluate the nutritional effects of mulberry leaf hay in broiler chickens. Five treatments were used: control (no mulberry, 3.16% CF); 15% mulberry (4.14% CF); 30% mulberry (5.09% CF), no mulberry (4.14% CF); no mulberry (5.09% CF). A randomized blocks design was used, with two blocks and three replications into the blocks to evaluate performance index, histopathological examination of the visceral organs and morphometric measurements of the hepatocyte nucleus and pancreatic acini. A poor performance index was observed for broilers feeding on mulberry leaves; lesions such as steatosis, proliferation of hepatic duct cells and multiple necrosis were found in the livers of the chickens fed with 30% mulberry (5.09% CF), as well as size reduction of the hepatocyte nucleus and pancreatic acini. From these data, it is concluded that mulberry probably has some toxic substance which can interfere in the improvement of diet ingredients, resulting in damage to broiler chickens.

Pulmonary adenocarcinoma in cattle

The Macroscopic, histological and immunohistochemical aspects of lung acinar adenocarcinoma and the presence of nodules in the abdominal cavity of an adult female bovine are reported. In the necropsy analysis samples were collected from the: lung, heart, spleen, liver, pancreas, kidney, uterus, intestine, brain, and from nodules found in the lung and abdominal cavity, which were routinely processed to be stained by hematoxylin-eosin and for an immunohistochemistry exam with the antibodies: cytokeratin (dilution 1: 200 mu L) and vimentin (dilution 1: 1000 mu L). The histopathological examination revealed neoplastic epithelial cells with acini formation. The immunohistochemical examination of the tumor cells showed positive marking for cytokeratin and the absence of marking for vimentin. According to anatomical, morphological, and histopathological findings, as well as the result of the immunohistochemical examination, the tumor was characterized as lung acinar adenocarcinoma.

Ultrastructure of the parotid and submandibular glands of the Old World marten (Carnivora; Mustelidae)

The morphology of the parotid and submandibular glands in the marten, a carnivore, were studied and analyzed under a transmission electron microscope. The nature of the granules in both glands, as well as in the acini and in the secretory tubules, is rather mucous. The structure of the secretory tubules is very characteristic, especially the striated ones. The myoepithelial cells are close to the acini and tubules and covered by the basement membrane separating them from the connective tissue, which enhances its epithelial origin. The cytoplasm of the basal parts of the acinar and tubular cells is abundant and separates the nucleus from the secretion granules. Although the morphology of the salivary glands of many carnivores is known, those of the parotid gland of the marten present peculiar characteristics, since they produce a rather mucous saliva and the granules, when forming, are far from the base as well as from the apex of the secretory cells. The submandibular gland contains granules of different densities, an aspect that in general resembles that of other animals.
