RESUMEN
@#ObjectiveTo investigate the effect of Jiuqiang Naoliqing(JNQ) on the TXA2 and PGI2 level in spontaneous hypertension rat (SHR) plasma.MethodsThe plasma was separated after the SHR and Wistar rats were treated with JNQ at the dose of 0.133g/kg,0.265g/kg,0.530g/kg and 1% carboxymethyl cellulose respectively for 5 weeks. The level of TXB2 and 6 keto PGF1α ,stable metabolin of TXA2 and PGI 2,in SHR plasma was tested by radioimmunoassay.ResultsThe level of TXB2 and the ratio of TXB2/6 keto PGF1α (T/P) in SHR plasma increased significantly(P<0.01),and there was no significant difference in the concentration of 6 keto PGF1α between Wistar rats and SHR plasma(P>0.05). JNQ could increase the generation of 6 keto PGF1α and decrease the level of TXB2 and T/P in SHR plasma after treated with different dosages for 5 weeks.ConclusionJNQ may improve the balance between TXA2 and PGI2 in SHR plasma.
