    ABSTRACT: Disturbances of the microcirculation and abnormal hemorheological properties are important factors that play an important role in disseminated intravascular coagulation (DIC) and result in organ dysfunction or failure. In the present study, we established an animal model of DIC using intravenous Dextran 500 in rats, and used exogenous normal lymph corresponding to 1/15 of whole blood volume for injection through the left jugular vein. We found that normal lymph could improve the blood pressure and survival time of rats with DIC. The results regarding the mesenteric microcirculation showed that the abnormality of the diameter of mesenteric microvessels and micro-blood flow speed in the DIC+lymph group was significantly less than in the DIC+saline group. Whole blood viscosity, relative viscosity, plasma viscosity, hematocrit (Hct), erythrocyte sedimentation rate (ESR), and electrophoresis time of erythrocytes were significantly increased in the DIC+saline group compared to the control group. The electrophoretic length and migration of erythrocytes from the DIC+saline and DIC+lymph groups were significantly slower than the control group. Blood relative viscosity, Hct, ESR, and electrophoretic time of erythrocytes were significantly increased in the DIC+lymph group compared to the control group. Whole blood viscosity, relative viscosity and reduced viscosity were significantly lower in the DIC+lymph group than in the DIC+saline group, and erythrocyte deformability index was also significantly higher than in the DIC+saline and control groups. These results suggest that exogenous normal lymph could markedly improve the acute microcirculation disturbance and the abnormal hemorheological properties in rats with DIC induced by Dextran 500.

    ABSTRACT: To investigate the effect of exogenous normal lymph on kidney injury in disseminated intravascular coagulation (DIC) rats and to probe its mechanism. The DIC model was established by intravenous injection of Dextran 500. After 6 min, normal lymph without cell components was infused in the lymph group. After 40 min, the renal and coagulation function indices and renal histomorphology were observed. Serum urea and creatinine in the model group were significantly higher than in the control and lymph groups. Renal morphological study showed red blood cell silting and casts forming in the model group. The prothrombin time (PT), prothrombin time ratio (PTR), activated partial thromboplastin time (APTT), and thrombin time of lymph and model groups were higher than those in the control group, whereas fibrinogen was lower. The PT, PTR, and APTT were prolonged in the lymph group than in the model group. The platelet functions of the lymph and model groups were higher than in the control group, but platelet aggregation rate and thrombosis-forming indices were lower than in the control group; the platelet adhesive and aggregation rates and thrombosis dry weight of the lymph group were lower than those of the model group. Exogenous normal lymph could alleviate kidney injury in DIC rats, which may be related to the improving coagulation function.
