摘要:
目的:研究胰胆转流(PBD)术造成的高胆囊收缩素(CCK)血症对小鼠小肠I细胞群落及胰腺细胞和胰腺消化酶含量的影响。方法: 40只雄性 Balb/C 裸鼠随机分为PBD组及假手术(SO)组,每组20只,分别实施PBD术和假手术。20 d后称重胰腺重量,并用酶联免疫吸附法测定血浆CCK,用免疫组化法在十二指肠中测定I细胞群落,在胰腺中检测CCK受体和增殖细胞核抗原,以酶联免疫吸附法测定胰腺组织中胰蛋白酶原、脂肪酶、淀粉酶的含量。结果:PBD组血浆CCK水平高于SO组 (t=16.59,P<0.01),胰腺重量也较SO组增加(t=2.51,P<0.05);且PBD组十二指肠内的I细胞多于SO组 (t=5.04,P<0.01)。进一步的胰腺检测显示,PBD组CCK受体表达增强(t=5.08,P<0.01)、增殖细胞核抗原增多(t=8.05,P<0.01);比较两组胰腺外分泌酶的组成,PBD组胰腺中的胰蛋白酶原 (t=4.31,P<0.01)、脂肪酶(t=2.15,P<0.05)的浓度增加;胰淀粉酶浓度虽然较SO组有增加的趋势,但差异无统计学意义(t=0.60,P=0.56);PBD组全胰蛋白酶含量(t=2.49,P<0.05)、脂肪酶含量(t=2.02,P<0.05)、淀粉酶含量(t=2.53,P<0.05) 均较SO组增高。结论:CCK可刺激胰腺发育,使小肠I细胞增生,选择性地增加胰腺中的胰蛋白酶原和胰脂酶储备。
Abstract:
Objective:To study the effects of hypercholecystokin(CCK) inemia induced by pancreaticobiliary(PBD) on the proliferation of small intestinal I cell and pancreatic cells and the composition of pancreatic exocrine enzymes in mice. Methods:Forty male mice were randomly divided into PBD group and sham operation(SO) group,with 20 in each group. After 20 days,the weight of pancreas was weighed,
