HYPOTHERMAL EFFECT OF TOTAL GLUCOSIDES OF PAEONY ROOT AND PRELIMINARY STUDY OF ITS MECHANISM / 中国药理学通报

Total glucosides of paeony root ( TGPs ) ( 5 ~40mg/kg, ip ) had a dose-related hypothermal effect in mice and rats, which was related to the environment temperature. But TGPs ( 40mg/kg, ip or iv ) showed no significant hypothermal effect in guinea-pigs or rabbits. TGPs ( 2, 4 mg/kg, icv ) had a potential hypothermal effect in rats. Chlopheniramine had antagonist effect on hypothermal effect of TGPs in mice and rats.
