Resumo: | The RT of domestic quail from Italian variety showed mainly an albuginic pattern being represented by tortuous channels lined predominately by a simple cubic epithelium. RT channels extended along the testicular albuginea and penetrates into the epididymal region (ER) through its myoconnective matrix. Passageways were continuous to proximal efferent ducts of the ER. Epithelium lining ultrastructure of RT passageways showed some differences between the spring and the inactive phase at middle fall, concerning the quail testicular reproductive cycle. The features observed in RT epitheliocytes in fall were the low cytoplasmic electrodensity, paucity of supranuclear vesicles, which were abundant and variable in form and shape in spring, and some degenerative aspects of cell organelles mainly in ER lamellae. Moreover, presence of apical cytoplasmic extrusions were verified in the fall. No marked features were seen in the RT ultrastructure during the winter and summer comparatively to the active phase of spring. |

Os canais da RT são contínuos com os ductos eferentes proximais da RE. A ultraestrutura do epitélio de revestimento da RT mostra diferenças marcantes na primavera - a fase proliferativa do ciclo reprodutivo, e em meados do outono - a fase quiescente do ciclo reprodutivo nesta ave. As características ultraestruturais marcantes dos epiteliócitos da RT, nestas duas fases, foram a baixa eletrodensidade citoplasmática e ocorrência de poucas vesículas e lisossomos no outono, que aparecem com maior freqüência na RT primaveril. Aspectos degenerativos de organelas, e presença de extrusões citoplasmáticas apicais, apareceram em número expressivo no outono, não se observando aspectos ultraestruturais marcantes nas estações de inverno e verão, relativamente às observações de primavera.Univ Estadual Paulista, Dept Anat, Botucatu, SP, BrazilUniv Marilia, Setor Morfofisiol Humana, Marilia, SP, BrazilFac Med Marilia, Dept Anat, Marilia, SP, BrazilUniv Estadual Paulista, Dept Anat, Botucatu, SP, BrazilUniversidade Federal de Uberlândia (UFU)Universidade Estadual Paulista (Unesp)Universidade de Marília (UNIMAR)Faculdade de Medicina de Marília (FAMEMA)Orsi, Antonio Marcos [UNESP]Dominiconi, Raquel FantinRoque, Domingos Donizetida Cruz, Claudinei2014-05-20T13:47:34Z2014-05-20T13:47:34Z2009-01-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article135-141application/pdfhttp://www.seer.ufu.br/index.php/biosciencejournal/article/view/6940Bioscience Journal.
