title: [Study on efficacy accompanied by side effects of water extraction components of Evodiae Fructus based on syndrome model].
abstract: The range of effective dose and mechanism of abirritation about water extraction components of Evodiae Fructus on the stomach cold syndrome model in mice were preliminary studied. The method of stomach cold-syndrome model in mice was built, which were administrated with different doses water extraction components of Evodiae Fructus, observing abirritation and toxicity by the classical hot plate method, detecting the level of ALT, AST, PGE2, NO, NOS, MDA, SOD, GSH, GSH-Px, BUN, CR in serum and ALT, AST in hepatic tissue, and recording toxicity symptoms in mice according to the list of relevant toxicity reaction. The water extraction component of Evodiae Fructus has obvious analgesic action after administration 30 min, arriving peak effect after administration 60 min, showing certain "dose-time-toxicity" relationship. ALT and AST levels in mice serum and liver tissue enhanced; PGE2, MDA, NO, NOS enhanced in mice serum; SOD, GSH, GSH-Px reduced; the BUN, CR levels was no significant alteration; liver weight/ body weight enhanced; kidney weight/body weight was no significant alteration. The a irritation mechanism of volatile oil of Evodiae Fructus was connected with suppressing pain transmitters release, per oxidative damage mechanism and NO damage, which also induced hepatotoxicity and the mechanism of hepatotoxicity is main lyoxidative damage, showing certain "dose-time-toxicity" relationship in accordance to hepato-toxicity injury.
