Toxic effects of Erycibe obtusifolia, a Chinese medicinal herb, in mice.
Department of Cellular Biology, Tzu-Chi Medical College, Hualien, Taiwan, ROC.
Extract of stem of Erycibe obtusifolia (EO) at doses of 10, 20 and 30 mg/kg was experimentally tested through oral and intraperitoneal administration. Toxic effects of EO were assessed through functional changes of the liver and kidneys. Mice died immediately following the i.p. injection at the dose of 10 mg/kg. However, no death occurred after the oral administration at the dose of 10, 20 or 30 mg/kg under close observations for at least 2 weeks. Changes of several functional parameters in both the liver and kidney appeared simultaneously after the oral administration. Although the higher dose increased the levels of serum glutamate-oxalate-transaminase (sGOT), serum glutamate-pyruvate-transaminase (sGPT), and blood urea nitrogen (BUN), and decreased the levels of hematocrit at 6 h after the treatment, no distinct dose-dependent relationship existed between the administered doses and the changes in functional parameters observed.
