摘要

本文应用胰岛累、胰升血糖素和生长抑累抗血清，通过免疫组化染色对ＳＴＺ诱导的糖尿病大鼠（Ｉ对照组）以及用小磺酸对其进行防治（Ⅱ防治组和Ⅲ治疗组）后胰岛的病理形态进行观察。结果：Ⅱ和Ⅲ组较Ⅰ组胰岛Ｂ细胞变性坏死程度明显减轻，且Ｂ细胞表达胰岛素呈阳性的胰岛分别占４４．６仍和３４．９％，均较Ⅰ组２３．３的增高，Ⅱ和Ⅰ级之间行显著差异（Ｐ＜０．０５）．三个组均见部分胰岛表达升血糖素的Ａ细胞发生明显增生。胰岛Ｄ细胞未见病理改变。我们的结果提示ＳＴＺ对胰岛Ｂ细胞具有直接的损伤作用；Ａ细胞的增生可能与ＳＴＺ有关，并参与了升高血糖效应。牛磺酸对ＳＴＺ造成胰岛Ｂ细胞的损伤具有比较明显修复作用。

Abstract

Pathological morphology of pancreatic islets in streptozotocin induced rats( I

control group) and taurine prevention and treatment diabetic rats(include Ⅱ

prevention and treatment group

Ⅲ

treatment group)was investigated by immunohistochemical method using insulin

glucogan and somatostatin antisera.The results showed that the degree of degeneration and necrosis weakened obviously for the pancreatic B-cells in Ⅱ and Ⅲ compared with I

the pancreatic islets of positive staining for insulin antiserum were 44.6% and 34.9% respectively

which was higher than that(23.3%)in I

and signoficant difference between Ⅱ andⅠ (P<0.05)was observed.Among all the three groups

hyperl- asia was seen in the panereatic A-cells

but no pathologic change demostrated in the pancrestic D - cells.The results indicate that streptozotocin can cause the direct damage to the B - cells and taurine has repairing effect against the damage of the pancreatic D-cells by streptozotocin.Hyperplasia of the A - cells my be related to administered streptozotocin and involved in hyperglycemia in Wistar rats.
