title: Uterotropic effect of beta-HCH, a food chain contaminant.
abstract: The uterotropic effect of beta-HCH was assessed in juvenile female mice and rats. A dose of 50 mg/kg feed over five days gave a significant increase in the uterine weight. The potency of beta-HCH compared to 17 alpha-ethynyloestradiol was about 20 X 10(-6). Based on these and other as yet unpublished observations, it is concluded that beta-HCH has oestrogenic features.
