RESUMEN
Aim To observe the fluctuation of uric acid in serum after replicating rat hyperuricemia model with hypoxanthine, uricase inhibitor singly or combined. Discuss the method of acute hyperuricemia replication on rats. Method Hypoxanthine was administered via stomach, uricase inhibitor was injected intraperitoneally, then inspect the uric acid in serum at different periods of time. Results When we combined hypoxanthine with uricase inhibitor, the uric acid in serum of different dose groups was higher than control group after 3 hours(P
RESUMEN
Objective To compare the analgesic effect of Semen Persicae (SP, Taoren), Flos Carthami (FC, Honghua), Siwu Decoction (SD) and Tao Hong Siwu Decoction (THSD) in dysmenorrhea model and the acetic-acid-induced pain model. Methods The dysmenorrhea model and the acetic-acid-induced pain model were established, and the pain threshold was compared in different mice models. Results On dysmenorrheal model, the analgesic effect of water extract supernatant and ethanol suspension of FC, SP polysaccharide, water extract supernatant and ethanol extract of SD, SD and THSD polysaccharide differed from that of blank control. On acetic-acid-induced pain model, the analgesic effect of water extract supernatant and ethanol suspension of FC, FC polysaccharide, ethanol extract of SP, SP polysaccharide, SP+ FC water extract, SP+ FC ethanol extract, SP+ FC polysaccharide, SD ethanol extract, SD polysaccharide, THSD water extract and ethanol extract, and THSD polysaccharide differed from that of blank control. Conclusion FC water extract and ethanol extract, SP ethanol extract, THSD polysaccharide, SD ethanol extract and SD polysaccharide have the best analgesic action, and then come with THSD water extract and ethanol extract, SP + FC ethanol extract, and SP + FC polysaccharide.
