Effect of Normal Lymph on Serious Shocks of Rats

Objective: To study the interference effect of lymph on superior mesenteric artery occlusion(SMAO) shock and serious hemorrhagic shock in rats.Methods: Ninty male wistar rats were randomly separated into six groups,three of which were made into SMAO shock model and three into hemorrhagic shock model.Then they were treated with the lymph,the plasma and normal saline as control.The blood pressure and the survival rate were observed after infusion of a little of lymph,and administration of the equivalent volume of plasma or normal saline(NS).Results: 1.The effects for SMAO shock: The blood pressure of the lymph group was higher than that of the model group during 70~120min after shock(P0.05) and also was higher than that the plasma group(P0.05),but there was no difference between the lymph and plasma gropes(P0.05).The survival rate of the lymph group in 3h was higher than that of the other groups(P0.05).2.The effects for hemorrhagic shock: The blood pressure of the lymph group was significantly higher than that of the model group(P0.05～0.01)during the experiment and higher than that of the plasma grope after infusing NS(P0.05～0.01);The blood pressure of the plasma grope during 5~10min of infusing plasma was higher than that of the modle grope(P0.05).The survival time of the lymph group was longer than that of the other groups(P0.05～0.01).Conclusion: Lymph could maintain the blood pressure and lengthen the survival time on SMAO shock and serious hemorrhagic shock in rats.
