摘要
探讨左旋精氨酸(L-Arg)在大鼠急性水肿性胰腺炎(AEP)中的作用。方法观察倍数剂量L-Arg治疗AEP大鼠后,血浆和胰组织一氧化氮(NO)浓度、血浆淀粉酶、平均动脉压(MAP)、胰组织病理的变化。结果AEP大鼠血浆、胰组织NO浓度明显降低,L-Arg50、100mg/kg升高血浆、胰组织NO浓度,改善了大鼠AEP;L-Arg800、1600mg/kg体重使NO浓度过度升高,加重AEP成为急性出血坏死性胰腺炎(AHNP);胰组织病理评分与血浆、胰组织NO浓度呈正相关。L-Arg对MAP的影响较小。血浆淀粉酶除800mg/kg体重组明显降低外,其余各组间无明显差异。结论L-Arg因升高NO浓度而参与了大鼠AEP的病理过程。
Objective To investigate the role of different doses of L-arginine in the treatment ofacute edematous pancreatitis in rat. Method The alterations of mean arterial pressure (MAP), serumamylase, nitric oxide in serum and pancreatic tissue, pancreatic pathohistology were studied. ResultContent of nitric oxide in serum and pancreatic tissue was correlated with the scores of pancreatic pathohistology significantly (r1=0. 48, r2=0. 63, P<0. 05). MAP was decreased and serum amylase increased, but didn't relate to the scores of pancreatic pathohistology. Conclusion L-arginine might beinvolved in the development of acute pancreatitis by increasing the content of nitric oxide.
