| 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... |

| Tubas uterinas de 21 novilhas mestiças Bos taurus taurus × Bos taurus indicus, em diferentes fases do ciclo estral natural (estro, metaestro e diestro) ou induzido pelo tratamento superovulatório (estro e metaestro superovulados), foram avaliadas quanto à presença de cistos intra-epiteliais e à caracterização histoquímica de seu conteúdo. Verificou-se a ocorrência de cistos intra-epiteliais nas tubas uterinas em todos os animais, mais freqüentes nas regiões do infundíbulo e ampola. Eles ocorreram nos lados direito e esquerdo, ipsi- e contralateral ao ovário ativo (folículo pré-ovulatório ou corpo lúteo), nas fases estrogênica e progesterônica do ciclo. No conteúdo cístico, houve predominância de mucinas neutras e ácidas carboxiladas, sendo as mucinas... |

| The objectives of this study were to evaluate the effects of pinealectomy, adrenalectomy and pinealectomy-adrenalectomy upon the quantification of spermatogenic cells of rats. As such, 32 adult Wistar rats with a mean body weight of 331.7± 15.5g were assigned into one of the following treatments: (a) a sham-operated control group, consisting of nine animals; (b) ten pinealectomized animals; (c) seven adrenalectomized animals and (d) six pinealectomized plus adrenalectomized animals. No significant differences were observed between groups for the following parameters: body, testes, prostate and seminal vesicle weights, seminiferous tubular diameter, number of cells per seminiferous tubular cross sections (primary spermatocytes at pachytene, round... |

| 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... |
