Pharmacological Study on Chaigeshubiao Granules / 医药导报

ABSTRACT

Objective To study the antipyretic,anti-inflammatory and analgesic effects of Chaigeshubiao granules. Methods Animals were randomly divided into 6 groupsblank control group,indomethacin group,Fengreganmao granules group and the high, the medium and the low dosage groups of Chaigeshubiao granules ( 26, 13, 6. 5 g . kg-1 ) . Each group was administered via intragastric administration once a day for 5 days.Rat model suffering from fever by dried yeast,relieving fever of Chaigeshubiao granules was investigated;Rats with toe swelling by 1% carrageenin and mice with ear swelling by dimethylbenzene were applied to observe anti-inflammatory effects of Chaigeshubiao granules were observed;The pain models induced by 0. 6%acetic acid and the hot-plate tests in mice were used to observe the analgesic effects of Chaigeshubiao granules. Results Compared with negative control group,Chaigeshubiao granules in high dosage could obviously decrease the temperature of rat with fever induced by dried yeast 0.5 h later,and the medium dosage group decreased 4-6 h later. Moreover,Chaigeshubiao granules in high dosage could inhibit inflammatory reaction of rat with toe swelling caused by albumen at 1 h,2 h,3 h,when the medium dosage group inhibited at 2 h,3 h,4 h. The inhibition ratio of the mice with ear swelling induced by dimethylbenzene was 58.2%, 52.0% and 53.9%,respectively at the high,medium and low dose groups. And the inhibition ratio of retortion of mice by 0.6%acetic acid was 50.5%,68.8%,58.1%,respectively, at the high,medium and low dose groups. In addition,the high,medium and low dose groups reduced the pain reaction latency of mice in the hot-plate tests. Conclusion Chaigeshubiao granules have antipyretic,anti-inflammatory and analgesic actions.
