Immunolocalization of NOS isoforms in the ductuli efferentes and epididymis of prepubertal and adult alpaca (Lama pacos).
The present research used immunohistochemistry to analyse the detection and localization of NOS isoforms in the ductuli efferentes and epididymis of prepubertal and adult alpaca. In the ductuli efferentes and epididymis of prepubertal and adult animals, nNOS and eNOS were similarly expressed in epithelial lining cells, conversely differences were observed in the immunopresence of iNOS. Our data...
متن کاملPermeability of Sertoli Cell Tight Junctions to Lanthanum after Ligation of Ductus Deferens and Ductuli Efferentes
The permeability of Sertoli cell tight junctions to lanthanum administered during fixation has been compared in rats after ligation of the ductus deferens and after ligation of the ductuli efferentes. In both control and vasoligated testes, lanthanum penetrated only short distances into the Sertoli cell tight junctions before stopping abruptly. The tight junction, consisting of numerous pentala...
متن کاملObservations on the anterior testicular ducts in snakes with emphasis on sea snakes and ultrastructure in the yellow-bellied sea snake, Pelamis platurus.
The anterior testicular ducts of squamates transport sperm from the seminiferous tubules to the ductus deferens. These ducts consist of the rete testis, ductuli efferentes, and ductus epididymis. Many histological and a few ultrastructural studies of the squamate reproductive tract exist, but none concern the Hydrophiidae, the sea snakes and sea kraits. In this study, we describe the anterior t...
متن کاملStructure and function of the ductuli efferentes: a review.
INTRODUCTION The ductuli efferentes are a series of tubules that conduct sperm from the rete testis to the epididymis . These small ducts are unique because they are the only region of the male reproductive tract that is lined by a ciliated epithelium. The presence of cilia seemed to have provided the impetus for their study starting with Becker in 1856 and 1857, who first described the cylindr...
متن کاملObservations on variation in the ultrastructure of the proximal testicular ducts of the Ground Skink, Scincella lateralis (Reptilia: Squamata).
The North American Ground Skink, Scincella lateralis, is a member of the most speciose family of lizards, the Scincidae. The only descriptions of the testicular ducts of skinks concern the light microscopy of 13 species in eight other genera. We combine histological observations with results from transmission electron microscopy on a sample of skinks collected throughout the active season. The ...
