应用免疫细胞化学方法对饥饿５ｄ大鼠和正常大鼠胰鸟α细胞进行显示，并用显微分光光度计和体视学技术对２组动物α细胞内胰高糖素的反应强度和α细胞在胰岛内所占数量和体积进行计量分析。结果表明：与正常对照组相比，饥饿大鼠胰岛α细胞内胰高糖素含量明显下降，但α细胞在胰岛内的相对数量和体积并无明显变化。提示：饥饿可导致胰高糖素释放，但由于大鼠胰岛α细胞在胰岛内并未出现相应数量和体积增加的代偿性改变，因此推测在持续性饥饿过程中α细胞对血糖不起主要调节作用。
Immunocytochemistry was used to detect the expression of α-cells in starvation 5d and normal pancreas birds. The response of α-cells to glucagon in the two groups of animals was analyzed by microdispectrophotometer and stereological techniques. Pancreas is the amount and volume of the measurement analysis. The results showed that compared with the normal control group, the content of glucagon in pancreatic α cells of starved rats decreased significantly, but the relative quantity and volume of α cells in islets did not change significantly. Hints: Starvation can lead to glucagon release, but due to the fact that rat islet alpha cells do not exhibit compensatory changes in volume and volume in islets, it is hypothesized that alpha cells do not contribute to glycemia during persistent starvation Regulatory effect.
