This study was undertaken to examine the possible effects of Artesunate(Art) on the hepatic reduced glutathione(GSH) content in normal and hepatotoxin - poisoned mice. It was demonstrated that Art given ip( 100mg?kg-1or 200mg?kg-1 ? 3)to mice had a signifcant protection against hepatic GSH deplection induced by acetaminophen and yellow phosphorus, andthat Art also caused a marked increase of the hepatic GSH content in fasting mice at the dose of 200mg ? kg-1. These results indicate that Art can help the liver detoxication of toxic metabolits in mice.

AIM: To study the exciting effects of ethanol extract of capitate phrynium (Phrynium Capitatum Willd) stem and leaf on the uterine smooth muscle of rat,mice,guinea pig and rabbit pretreated by diethylstilbestrol. METHODS: Conventional method was adopted to prepare animal uterine specimens both in vivo and in vitro. Different doses of the extract were given to the specimens and recorded their tensility, frequency and activity of contraction with the help of BL-420 biological experimental system. IC_(50) of the extract was calculated, with oxytocin as standard comparison. RESULTS: 95% ethanol extract and 50% ethanol extract of capitate phrynium and leaf had obviously stimulating action on the uterine smooth muscle of rat, mice, guinea pig and rabbit in a dose-dependent manner in vitro, whichinclude accelerating contraction frequency, raising tension (P<0.05, P<0.01). In addition, 50% ethanol extract also had a significant stimulating action on uterine smooth muscle of rabbit in vivo(P< 0.01). CONCLUSION: Ethanol extracts of capitate phrynium have an effect on rodent uterine. Smooth muscle indicates that clinical application of Chinese practitioner used to treat the dysfunctional uterine bleeding proves to be effective.
