ABSTRACT
Objective To discuss the feasibility of using serum complement C5a and C5b-9 as predictive indicators of liver injury severity in traumatic rats with hemorrhagic shock.Method Fifry healthy male Wistar rats were randomly(random number)divided into normal group,model 1 hour group,model 3 hours group,model 6 hours group,and model 24 hours group.Plasma CH50,C5a and C5b-9 were detected by using enzyme-linked immunosorbent assay,and rate method was used for determination of plasma aspartate aminotransferase.Paraffin sections of hepatic tissues were used to observe the damage of liver.Results In the model l h group,the CH50 increased significantly and reached the highest value,it began to decline in 3 hours group,and it reached the lowest point in 24 hours group.Compared with the model 3 hours group,6 hours group,and 24 hours group,the level of CH50 in model 1 hour group increased more significantly(respectively P<0.05).A small amount of C5b-9 in the normal group was detected.In the model 1 h group,C5b-9 increased significantly and reach the peak compared with 3hours group,6hours group and 24 hours group,respectively(P<0.05),but in the model 3hours,it began to decline,and in 24 hours group,it reduced to minimum.C5a increased insignificantly in the model 3 hours group,6 hours group and 24 hours group,and peaked in 24 hours group compared with normal group(P<0.05).Aspartate aminotransferase in the model 1 hour group increased significantly and peaked in 24 hours group compared with other groups(P<0.05).Conclusions A large number of complements are activated in the seRing of hemorrhagie shock.C5b-9 and CH50 increase significantly in the early stage,and C5a.increases significantly in the later stage.C5b-9 can be considered as,an initiative factor of liver injury.The low levels of C5a in the early stage may be a mechanism of self-protection of the body.The high levels of CSa in the later stage may be a kind of decompensation,and C5a can be used as a late predictor of disease severity.
