| The changes of red and white blood cells counts in intact and castrated rats with hyperthyroidism were analysed. A total of 108 five-month-old female Wistar rats, divided into four groups, were used as following: euthyroid castrated, euthyroid intact, hyperthyroid castrated and hyperthyroid intact. Nine animals of each group were killed at 30, 60 and 90 days to evaluate the red and white blood cells counts. The conclusion was that castration or hyperthyroidism did not affect both the red and white blood cells. |

| The present report describes the clinical and pathological findings related to diffuse heterotopic hairs associated with pseudo-placentational endometrial hyperplasia in a canine uterus. Macroscopically, the uterus was intensely enlarged and thicker, and the endometrial surface was irregular and covered with black hairs similar to the hairs of the bitch. Histologically, heterotopic hairs associated with pseudo-placentational endometrial hyperplasia were observed. |

| The influence of the estrous cycle on the thyroid gland was studied. Twenty one five-to-seven-month-old Wistar female rats were divided according to the stage of the estrous cycle in two groups: metaestrus-diestrus and proestrus-estrus. After gross inspection, the thyroids were weighed, sampled, and processed for staining with hematoxilyn-eosin. Seric concentrations of total T4, free T4, total T3, TSH, progesterone, and estradiol were measured. The values of estradiol were significantly higher in the proestrus-estrus stage. However, no significant differences in the plasmatic concentrations of progesterone, free T4, total T4 and TSH throughout the cycle were found. The results of the morphometric study of the thyroid did not indicate any significant... |

| The aim of this work was to perform a morphometric analysis of the uterine tube epithelium of sexually mature sows, with or without pathological changes. The sows were either in follicular or luteal phases. One hundred and twenty-four uterine tubes of sixty-two sows were obtained from slaughterhouses. Sections of the uterine tube, uterus and ovary were processed for morphometrical evaluation. The uterine tubes were divided into four groups. The first (LSP) group was composed by animals in luteal phase without pathological changes (n=45), the second (LCP) by animals in luteal phase with pathological changes (n=19), the third (FSP) by animals in follicular phase without pathological changes (n=45) and the fourth (FCP) by animals in follicular phase with... |

| Hemogram and serum biochemistry (aspartate aminotransferase, alkaline phosphatase and gamma glutamiltransferase, total protein, urea, creatinine, calcium and phosphorus) were performed weekly in five crossbreed bovine after consumption of a diet containing citrus pulp pellets (40%), for 43 days. Percutaneous hepatic biopsy and histologic evaluation were performed in each animal before and after consumption of the citrus pulp diet. Hemogram, the enzymes aspartate aminotransferase and gamma glutamiltransferase, urea and creatinine had normal levels at the end of the experiment. No histologic lesions were observed in liver samples before or after citrus pulp consumption. However, there was an increase of serum phosphorus and reduction of serum calcium... |

| A influência do hipogonadismo sobre a função tireoidiana de ratas hipertireóideas e eutireóideas foi medida com base no perfil sérico dos hormônios tireoidianos, dos esteróides ovarianos e do TSH e na histomorfometria da tireóide. Ratas Wistar, com cinco meses de idade, castradas, foram mantidas em estado eutireóideo ou hipertireóideo por períodos de 30, 60 e 90 dias. Um grupo não castrado foi mantido nas mesmas condições e serviu como controle. O hipertireoidismo foi induzido mediante a administração diária 50µg de L-tiroxina, por sonda gástrica. Ao final de cada período, nove ratas por grupo tiveram suas tireóides inspecionadas, pesadas e processadas para avaliação histomorfométrica e o plasma sangüíneo colhido para dosagem de estradiol, progesterona, T4... |

| Sixty-four ovaries of adult woolly sheep from the Centro de Pesquisa dos Campos Sul Brasileiros - Embrapa, Bagé-RS, Brazil, were analyzed histologically. The presence of the rete ovarii was detected in 55 of the 64 ovaries (85.9%), located in the periovarian tissue, in the hilus and in the medullary or cortical regions. As also observed in other mammals, the rete ovarii of sheep is morphologically divided into three portions: intraovarian rete, connecting rete and extraovarian rete. Continuity between the extraovarian rete and the uterine tube was observed in five ovaries (7.8%), suggesting a tuboretial connection, as reported for cows and does. Pathological examination of the rete showed the formation of cysts surrounding the connecting and/or... |

| Uma chimpanzé de 22 anos de idade foi necropsiada com histórico clínico de anorexia, vômitos freqüentes e desidratação conseqüentes à gastrite iatrogênica. Macroscopicamente, o útero apresentava-se aumentado de volume, com o lúmen totalmente ocluído por nódulos firmes, esbranquiçados e coalescentes que se estendiam para o miométrio. Histologicamente, os nódulos eram constituídos por leiomiócitos bem diferenciados dispostos em várias direções e com coloração característica pelo tricrômio de Gomori e Masson. Pela imunoistoquímica, as células neoplásicas apresentavam marcação forte e difusa de receptores para progesterona e estrógeno, assim como de actina alfa de músculo liso. Algumas células neoplásicas e o estroma apresentavam marcação para vimentina e... |

| The goal of this study was to determine whether the quantification of the nucleolar organizer regions (AgNORs) is a useful parameter for evaluation of the proliferative potential of non-neoplastic granulosa cells in ovarian follicles at different stages of development. Seven ovaries from six-month-old rats, all of which in metestrus-diestrus, were studied. The number of AgNORs from 60 granulosa cell nuclei was quantified in secondary follicles with two to three layers of cells and in follicles with more than five layers of granulosa cells. Follicles with two to three layers had larger AgNORs in lower numbers, whereas more developed secondary follicles the AgNORs were predominantly smaller, scattered throughout the nucleus, and in significantly higher... |
