The present study deals with the stereological analysis of the changes in the seminiferous epithelium of rat testis, mediated either by cadmium alone or by cadmium plus zinc, chronically administered at low oral doses. Stereological estimates of both labeling indices of proliferative cell nuclear antigen and TUNEL-stained nuclei of spermatogonia, and of(More)
Gentianella alborosea ("Hercampure") is a Peruvian species used in folk medicine for the treatment of a variety of health disorders. We tested the free radical scavenging (DPPH) and induction of apoptosis on a human uterus tumor cell line (HeLa) by its methanolic extract. The results showed a noticeable radical scavenging activity and a dose-dependent(More)
The incidence of certain cancers, including prostate cancer, is considerably higher in western countries than in Southeast Asia. Many studies have linked soy consumption to the lower incidence of prostate cancer in these countries. Twenty male Sprague-Dawley rats were randomized and divided into a control group and a group treated with soy. The ventral(More)
Background: Cadmium chloride is an environmental toxic that affects the male reproductive system. This study was directed 1) to evaluate whether long-term oral exposures to low doses of Cd in rats causes morphological changes, 2) the immunohistochemical TJ and AJ protein expression; and 3) to evidence that zinc exposure can modify Cd effects.
