Comparison of Analgesic Effects of Zhentongning Capsules Prepared by the New and old Technology on Mice

Objective ： To compare the analgesic effect of zhentongning eapsules prepared by the new and old technology on mice. Method ： The analgesic effect of zhentongning capsules prepared by the new and old technology were observed by the hot-board method and the writhing assay in mice, respectively. Result： Compared with the old technology, the inhibition of the thermal stimulation-induced pain and the acetic acid-induced writhing in mice arisen from the zhentongning capsules prepared by the new technology increased significantly （ P 〈 0.01 ）. Conclusion ： The analgesic effect of zhentongning capsules prepared by the new technology is obvious and it is superior to the old one.
