ABSTRACT
Objective To investigate the therapeutic effect of ehlorpromazine in rats with acute necrotizing pancreatitis (ANP). Methods 120 healthy female SD rats were randomly divided into three groups normal control group (NC group, n=30); acute necrotizing pancreatitis group (ANP group, n=45) and chlorpromazine treatment group (CPZ group, n=45). ANP was induced by the injection of 5% sodium taurocholate (1 ml/kg) into pancreatic duct, NC group were injected with same amount of saline. 0.4% chlorpromazine (0.25 ml/100 g) was intraperitoneally administered in CPZ group at 0 h, 24 h, 48 h after ANP was established. Same amount of normal saline was given to ANP group and NC group in the same way and at the same time points. The rats were sacrificed at 24, 48, 72 h after ANP was induced. The blood samples were collected for analysis of serum amylase (AMY), phospholipase A2 (PLA2), interleukin-6 (IL-6). Pancreas was harvested for evaluation of pathologic changes. Results The pathologic changes in ANP group were compatible with pathologic changes of ANP. The pathologic scores in CPZ group was 3.57±0.73 at 72 hours after ANP induced, which was significantly lower than 13.29±1.03 in ANP group. The serum amylase and PLA2 levels in CPZ group at 72 hours after ANP induced were (1658.0±277.0) U/L and ( 12.26±1.40) ng/ml respectively, the corresponding values of ANP group were (3666.7±1233.0) U/L and (16.81±1.13)ng/ml, respectively. The difference was statistically significantly (P<0.01). The serum IL-6 levels of CPZ group at 24,48 72 hours were (116.27±14.49) pg/ml, (75.35±6.17) pg/ml, (82.75± 8.86) pg/ml respectively, the corresponding values of CPZ group were (160.88±27.19) pg/ml, (111.77± 19.10)pg/ml, (125.51±30.71) pg/ml respectively. There was a significant difference between the two groups (P<0.01). Conclusions Chlorpromazine may have a therapeutic effect on ANP.
