Abstract:
To compare the blood-cooling and hemostasis effects of Rehmanniae Radix before and after carbonizing on rats with blood heat and hemorrhage syndrome. The blood heat and hemorrhage syndrome rat model was established. Indexes including rectal temperature,whole blood viscosity,plasma viscosity,thrombin time(TT),activated partial thromboplastin time(APTT),prothrombin time(PT),fibrinogen content(FIB),red blood cell(RBC),hemoglobin(Hb),hematocrit(HCT),blood platelet count(PLT),mean platelet volume(MPV),serum IL-1,serum IL-6 and lung histopathology were detected to investigate the blood-cooling and hemostasis effects of Rehmanniae Radix and its carbonized products. Compared with the blank control group,the rectal temperature was significantly increased with rise of the high,middle and low whole blood viscosities and plasma viscosity(P<0.05); both the high and low whole blood restore viscosity and the high and low whole blood relative viscosity were increased significantly(P< 0.05); TT,APTT and PT were notably prolonged with the increase in FIB content(P<0.05); RBC,Hb and HCT increased significantly(P< 0.05); concentrations of serum IL-1 and IL-6 were also increased(P< 0.05) in model group. Additionally,obvious hemorrhages in lung and stomach were observed in rats of the model group. Rehmanniae Radix and its carbonized products can significantly reduce rectal temperature,high middle and low whole blood viscosities and plasma viscosity(P<0.05). TT and APTT were shortened,with lower expression of FIB in group of Rehmannia Radix and its carbonized products. Hemorrhages of lung and stomach were improved by Rehmannia Radix and its carbonized products. The results indicated that Rehmannia Radix before and after carbonizing had the hemostasis and blood-cooling effects by promoting coagulation,improving blood rheology and inhibiting expressions of IL-1 and IL-6.
