摘要
目的 探讨内源性二氧化硫(sulfur dioxide,SO2)在重症急性胰腺炎(severe acute pancreatitis,SAP)大鼠胰腺组织、肝组织、肾脏组织、肺组织及血清中的分布与水平变化.方法 雄性SD大鼠32只,随机数字法分为假手术组、SAP 3 h组、SAP 6 h及SAP 12 h组(每组8只).SAP大鼠模型通过胰胆管逆行注射5%牛磺胆酸钠制作.造模后3h、6h及12h处死大鼠,酶联免疫吸附试验测定胰腺组织、肝组织、肺组织、肾组织及血清标本SO2.结果 SAP 3 h大鼠胰腺组织、肝组织、肺组织、肾组织及血清中SO2含量分别为(1.62±0.11) μmol/g、(1.72±0.14) μmol/g、(1.65±0.11) μmol/g、(1.12±0.06)μmol/g、(14.61±0.68) μmol/g.与假手术组比,差异无统计学意义(P>0.05).SAP 6 h大鼠胰腺组织、肝组织、肺组织、肾组织及血清中SO2含量分别为(1.89 ±0.17) μmol/g、(1.92±0.16) μmol/g、(1.91±0.15) μmol/g、(1.30±0.10) μmol/g、(16.80±1.27) μmol/g.与假手术组相比,各组织SO2含量升高,差异有统计学意义(均P <0.05).SAP 12 H胰腺组织、肝组织、肺组织、肾组织及血清中SO2含量分别为:(2.31±0.23) μmol/g、(2.22±0.15) μmol/g、(2.17±0.07) μmol/g、(1.55±0.11) μmol/g、(16.80±1.27)μmol/g.与假手术组相比,SO2含量升高,差异有统计学意义(P<0.05).结论 SAP大鼠体内SO2水平高于正常,可能与重症急性胰腺炎有一定的相关性.
Objective The present study is to investigate the distribution of endogenous sulfur dioxide (SO2) in severe acute pancreatitis (SAP) rats.Methods Thirty-two SPF male Sprague-Dawley rats were randomized (random number) into sham operation group,SAP rat 3 h group (SAP 3 h),SAP rat 6 hgroup (SAP6h),SAP rat 12 hgroup (SAP 12 h),n=8 in each group.The SAPmodel rats were induced by retrograde cholangiopancreatic infusion of 5% sodium taurocholate.Rats were sacrified 3 h,6 h or 12 h after treatment.,then we collected pancrease,liver,lung,kidney and serum.The SO2 concentration in each tissue or serum was detected by enzyme-linked immune sorbentassay.Results The concentration of SO2 in tissues of pancreas (1.72 ± 0.14) μmol/g,liver (1.62 ± 0.11) μmol/g,lung (1.65 ± 0.11) μ.mol/g,kidney (1.12 ± 0.06) μmol/g or serum (16.80 ± 1.27) μmol/g in SAP 3 h rats was not significant compared with the sham operation group (P 〉 0.05 in each group).The SO2 content in the pancreas (1.89 ± 0.17) μmol/g,liver (1.92 ± 0.16) μmol/g,lung (1.91 ± 0.15) μmol/g,kidney (1.30 ± 0.10) μmol /g and serum (14.93 ± 1.00) μmol /g of SAP 6 h was significantly increased compared with sham operation group (P 〈 0.05 each group).The content SO2 in the pancreas (2.31 ± 0.23) μmol /g,liver (2.22 ± 0.15) μmol /g,lung (2.17 ± 0.07)μmol /g,kidney (1.55 ± 0.15) μmol /gand serum (18.88 ± 1.56) μmol /g of SAP rats reached the peak 12Hafter treatment and was significantly higher compared with the sham operation group (P 〈 0.05).Conclusions The increase of SO2 concentration in SAP might be,at least in our present opinion,involved into the pathogenesis of SAP rats.
