RESUMO
Objective To investigate the effects of arginine combined with leptin in treatment of rats with a-cute pancreatitis. Methods Sixty Wister rats were randomly divided into sham operation group (group A), acute pancreatitis group (group B),arginine group (group C),leptin group (group D),arginine plus leptin group (group E),with 12 rats in each group. Acute panereatitis model was developed by retrograde injection of 5% sodium tauro-cholate into cholangiopancreatography in rats. After 6 hours, medicine were given by intraperitoneal injection, ab-dominal aortic blood and pancreatic specimens were taken for measurement of tumor necrosis factor-α(TNF-α), ser-um amylase,nuclear factor-κB (NF-κB) activity of pancreatic tissue, and pathological damage score of pancreatic tissue. Results TNF-α,Amylase,NF-κB activity, pathologic scores were(1.206±0.446)μg/L, (1617.2±18.8) U/L,0.174±0.013,0.6±0. 2 in group A;(3.201±0.321) μg/L, (4643.8±303.4) U/L,0.397±0. 025,7.8±1.3 in group B;(1.845±0.404) μg/L,(3370.9±173.2)U/L,0.255±0.026,3.9±1.1 in group C;(1.996±0.374) μg/L, (3693.7±208.0)U/L,0.274±0.062,4.2±1.2 in group D;(1.440±0.287)μg/L, (2501.0±771.4)U/L,0.211±0.027,2.3±1.0 in group E. Compared with group A, the indicators were significantly in-creased in group B (P < 0.05). Compared with group B, these indicators were reduced in group C and D (P <0.05). There was no significant difference between group C and group D. These indicators in group E were signifi-cantly lower than those in group C and D (P < 0.05). NF-κB in pancreatic tissue were positively correlated with other indicators(P <0.01). Conclusions In treatment of acme pancreatitis in rats, arginine combined with leptin has idenditfied effect, and the effect of combination therapy is better than that of separate medicine.
