RESUMEN
AIM: To evaluate the effects of compound salivia miltorrhiza injection on an experimental model of kidney thrombus induced by lipopolysaccharide(LPS).METHODS: The model of microvascular thrombosis in the rabbits' kidney was performed by the method of Hermida,which was induced by infusing LPS.Treatments were begun simultaneously with LPS infusion,through the contralateral marginal ear vein.Six different groups were established: NS 10(ml?h~(-1)) was infused as the negative control group,compound salivia miltorrhiza injection was infused with the dosage of(0.1)(Low-dose),(0.2)(medium-dose),and 0.4(high-dose)(ml?kg~(-1)?h~(-1)),heparin 600,000(IU?kg~(-1)?h~(-1)) as positive control group.The further rabbits, which were given neither LPS nor compound salivia miltorrhiza injection,were infused with saline solution through both marginal ear veins.The measurement of fibrinogen concentrations and platelet counts were used to assess the degradation of microvascular thrombosis.Kinney sections were examined for the presence of fibrin microthrombi.RESULTS: Compound salivia miltorrhiza injection was infused with the dosage of(0.1)(Low-dose),(0.2)(medium-dose),and(0.4)(high-dose)(ml?kg~(-1)?h~(-1)),and the fibrinogen concentrations and blood platelet counts were improved,and the fibrin deposition was degraded.CONCLUSION: Compound salivia miltorrhiza injection can inhibit effectively LPS-induced renal microvascular thrombosis.
