【摘要】 目的研究高渗盐水治疗重症急性胰腺炎(severeacutepancreatitis,SAP)时大鼠炎性细胞因子、胰腺、肺组织病理损害的变化及其机制。方法Wistar大鼠48只,均分成对照组、SAP模型组、等渗盐水组、高渗盐水组,采用过量L精氨酸诱导大鼠SAP模型,等渗盐水组、高渗盐水组于24h、48h分别经静脉输入2mlkg的09%NaCl、75%NaCl,在48h、72h取血测肿瘤坏死因子α(TNFα)、白细胞介素6(IL6)、IL10水平,于72h检查大鼠胰腺、肺组织病理变化。结果高渗盐水组胰腺和肺组织病理学改变明显轻于等渗盐水组;等渗盐水组血清TNFα、IL6、IL10水平在48h和72h分别为[(311±22)、(43±5)、(22±4)]pgml和[(403±29)、(66±7)、(28±6)]pgml。高渗盐水组分别为[(278±20)、(38±6)、(26±7)]pgml和[(329±28)、(42±6)、(44±5)]pgml;高渗盐水组血清TNFα、IL6值明显低于等渗盐水组,IL10值明显高于等渗盐水组,尤其在72h两组之间差异有显著意义。结论高渗盐水治疗大鼠SAP能使血清TNFα、IL6水平显著降低和IL10水平显著增高,减轻胰腺、肺等组织损伤。更多还原

【Abstract】 Objective To investigate the effect of hypertonic saline in the management of murine experimental severe acute pancreatitis (SAP) Methods SAP was induced in Wistar rats by intraperitoneal injection of 20% L Arginine Rats were divided into four groups ( n =12 in each group ); Healthy controls received intraperitoneal injection of distilled water of 5 ml/kg body weight initially Rats in the four groups were infused at 24 h and 48 h respectively at a dosage of 2 ml/kg body weight of distilled water in both healthy contrals, and SAP controls, of normal saline in group 3 and of hypertonic saline (7 5% sodium chloride) in group 4 Blood samples were collected at 48 h and 72 h after last injection for the measurement of plasma TNF α、IL 6、 IL 10 All rats were sacrificed for histopathology of pancreatic and lung tissues at 72 h Results Animals that received hypertonic saline showed less pancreatic and lung damage than those resuscitated with normal saline Plasma levels of TNF α、 IL 6 decreased significantly and plasma levels of IL 10 increased more significiently at 72 h after induction of SAP Conclusion Hypertonic saline resuscitation result in a significant attenuation of the systemic inflammatory response to severe acute pancreatitis更多还原
