| dc.description.abstract | The occupational chemicals 4-vinylcyclohexene (VCH) and butadiene diepoxide (BDE) have shown an ovarian effect in small pre-antral follicles in mice and rats (Flaws et al., 1994b; Doerr et al. , 1995). VCH exists as two enantiomers, S-VCH and R-VCH. Daily dosing with the enantiomers affected small primary follicles and wet tissue weights in B6C3F₁ mice. The S-enantiomer decreased small primary follicle numbers (P < 0.05) and both enantiomers reduced the weights of the ovary and uterus (p < 0.05). The results suggest the S-VCH enantiomer may have a greater ovotoxic effect as compared to the R-VCH enantiomer. In F344 rats, daily dosing with BDE reduced overall body weight (p < 0.05). There was no affect on ovarian follicle numbers. However, other ovarian effects were seen: decreased ovarian weights, delayed vaginal opening, decreased CL numbers and decreased caspase-3 activity in large antral follicles. Overall, BDE had a general toxic effect with a more specific effect in the ovary. | |
