 AB    Trichosanthin was administered intramuscularly into mature male ICR mice
       at a dosage of 0.2mg/25g, daily for three days. The mice were sacrificed
       four hours after the last injection. Their brains were dissected out and
       divided into three regions: A(thalamus and hypothalamus), B(cerebral
       cortex) and C(cerebellum and brainstem). Their pituitaries were also
       removed. The pituitaries and the various brain regions were extracted
       with hot 1M acetic acid. The extracts were lyophilized and reconstituted
       in radioimmunoassay (RIA) buffer before assay for beta-endorphin by RIA.
       It was found that there was a significant elevation of beta-endorphin
       concentration after trichosanthin treatment only in brain region A. The
       data suggest that trichosanthin does not adversely affect the brain.
