The epididymal region of the domestic duck is composed by efferent ductules, whose histotopology was characterized by the proximal and distal ductules and sequentially by the epididymal duct. The epithelial lining of the efferent ductules was ciliated pseudostratified and formed by columnar cells. Also the ducts epididymidis epithelium was pseudostratified but non-ciliated. Concerning the histomorphometric analysis, the epithelial height mean was significantly greater in the distal efferent ductules, differing from the lower epithelium height mean observed in proximal efferent ductules and epididymal duct. The maximum and minimum diameter mean were significantly greater in the proximal efferent ductules, comparatively to the same diameter means of the... |

Neste estudo diferenças expressivas foram observadas na estrutura dos ductos eferentes distais (DED) de codorna doméstica Coturnix coturnix, da variedade italiana, mantida em cativeiro experimental durante dois anos, durante as quatro estações do ano. A variabilidade morfológica dos DED foi mais marcante na primavera e no outono, eqüivalendo às fases ativa e quiescente do ciclo reprodutivo anual (ciclo testicular) nesta ave. Nessas fases do ciclo, diferenças significativas foram observadas na ultraestrutura das células principais (P) e ciliadas (C) do epitélio de revestimento tubular e nos calibres tubulares. Estes tiveram valores médios maiores na primavera, com valores similares no verão e no inverno, e valores médios menores observados no outono. Na... |

The surface epithelium of the vas deferens of Agouti paca, a wild and large South American rodent, was basically formed by principal and basal cells being only the principal cells related to endocytosis processes and also secretion taking base on their cytoplasmic ultrastructural features. Principal cell of vas deferens epithelium were characterized mainly by presence of vesicles with several shapes, sizes and internalized content at their apical cytoplasm occurring smaller pits and pale small vesicles seen next to the apical brush border of microvillus. Moreover, coated vesicles, smooth surface vesicles and great vesicles; multivesicular bodies, endosomes and lysosomes were seen. Presence of an apocrine secretory apparatus was also viewed, showing apical... |
