Structural and ultrastructural alterations of epithelial cells of vas deferens caused by contrast medium

RESUMO

In a attempt to verify experimentally any possible alterations of epithelial cells of vas deferens caused by radiopaque substance, the right and left vasa deferential of 3 rats were injected respectively with saline solution (0.9 per cent NaCl) and Conray-400 (66.8 per cent sodium iodomethamate). 72 hours later, the animals were killed by cranial trauma and histolofical sections and electronmiucrographs of their vasa deferentia were observed. The histological sections of epithelial cells of left vasa deferentia showed a decrease in height and slight changes in stereocilia as compared with those of right contralateral vasa deferentia. Electronmicrographs displayed a reduction in number and size of stereocilia and alterations of many mitochondria in epithelial cells of left vasa deferentia
