OBJECTIVE:To investigate whether Fuzi(Radix Aconiti Praeparata) has fewer "hot" characteristics when administered without Ganjiang(Rhizoma Zingiberis).METHODS:Differences in the thermotropism behaviors of mice treated either with Fuzi(Radix Aconiti Praeparata),Ganjiang(Rhizoma Zingiberis) or the combination of the two given intragastrically were investigated using the Animal Thermotropism Behavior Surveillance System.The water intake volume,oxygen consumption volume,adenosine triphosphatase(ATPase) activity,total antioxidant capacity(T-AOC) and total superoxide dismutase(T-SOD) activity were determined during the investigation.RESULTS:When Fuzi and Ganjiang were administered together,the rate at which mice remained on a warm plate("remaining rate") and the times and distances of their movement were all significantly reduced(P
