Abstract
Summary
Focal liver necrosis occurred in 30% of 500 mice which survived the intravenous injection of single sublethal quantities of toxic extracts′ of endometrium or placenta. Occasional similar lesions were seen in mice which were injected with other tissue extracts. Although related to the effect of the injected toxic material from endometrium or placenta, the lesions may be indirect or nonspecific effects of the injections.
Special apptreciation is due Miss Carol Spaulding for assistance in conducting this investigation.
