摘要: 目的:探讨鲨鱼肝活性肽S-8300 对糖尿病小鼠受损胰岛β 细胞和肾小球细胞凋亡的影响。方法:用电镜和DNA 电泳检测了S-8300 对四氧嘧啶(ALX) 糖尿病小鼠的胰岛细胞和肾小球细胞凋亡以及测定S-8300 对血清NO 和一氧化氮合成酶(NOS)水平的影响。结果:电镜检测显示S-8300 处理组小鼠可使ALX 所致的胰和肾在亚显微结构上的细胞凋亡特征消失, DNA 电泳检测表明S-8300 处理胰腺和肾组织DNA 后梯带消失, 能显著降低ALX 糖尿病小鼠的血清NO 和NOS 水平。结论:S-8300 的抗ALX 损伤与抗凋亡有关, 可能是其降血糖作用的机制之一。

Abstract: AIM: To evaluate the effect of active peptide from shark livers, S-8300, on beta cell of islet and renal glomeruli cells in alloxan induced diabetic mice.METHODS: The anti-apoptotic effect of S-8300 on diabetic mice was investigated by observing pancreas and kidney cells under electron microscope and DNA electrophoresis.The changes of NO and NOS in serum were also been deteced.RESULTS: The ultrastructural apoptosis lesions in pancreas and kidney cells in S-8300 groups were obviously alleviated and significant decrease of NO and NOS in serum was observed in diabetic mice treated with S-8300.CONCLUSION: The hypoglycemic effects of S-8300 was related with its protective activity against the apoptosis.

Key words: S-8300, diabetes, apoptosis, NO
