[Toxic studies on various processed products of Fructus Psoraleae]

Toxic studies on Fructus Psoraleae (FP) and its processed products are carried on. LD50 is 37.7 +/- 0.54 g crude drug/kg in oral administration of raw FP in comparison with 43.25 +/- 6.1/kg in that of Salt-bake one in mice. When 5.0 g/kg is given by oral for 14 days, the wet weight of testicles, preputial galnds, prostate and semianl vesicle is decreased in raw FP and its stir-bake tested groups. The wet weight of preputial glends, prostate, seminal vesicle in Lei Gong's Procession group, or prostate, and seminal vesicle in salt-steam group is also decreased to a certain extent. But no significant change on the weight of those sex organs is found in liquor-bake or salt-bake procession group, The glomerulal cell hyperplasia and cloudy swelling of renal tubules are induced by administration of raw FP in pathological examination.
