Effects of nitrous oxide on the female gonad in the rat

, : Effects of nitrous oxide on the female gonad in the rat. Bollettino Della Societa Italiana di Biologia Sperimentale 58(9): 527-531

Female rats have been exposed (24 hours for 15 days) to N2O 60% in normo-oxic blend of N2 and O2. Vaginal smears have been observed daily. At the end of the experiment the ovaries have been removed and the following morphological parameters have been statistically evaluated: number of evolutive follicles and corpora lutea, amount of interstitial tissue. Our results seem to account for a remarkable toxic effect of N2O on the rat gonad. Such effect is testified by alterations of the oestrous cycle and, at the ovary, a decrease in the number of evolutive follicles and functioning corpora lutea and by a sharp increase of atretic phenomena.

Effects of separate and combined action of 232Th and Cd on Allium cepa root tip cells were investigated. It has been shown that cytogenetic effects of 232Th results mainly from its ability to induce genome damages. Cadmium in the examined concentr...
