摘要: 本实验通过小鼠模型,研究了蚕卵粉对诱导型糖尿病小鼠的血糖、SOD酶和SOD基因mRNA表达的影响。结果显示,喂食含5%蚕卵粉饲料的糖尿病小鼠的血糖显著降低,蚕卵粉对正常小鼠的血糖值没有影响。蚕卵粉对由于高血糖引起的超氧化物歧化酶(SOD)活性降低具有明显保护作用,可以有效地增强糖尿病小鼠的SOD酶活性。RT-PCR和Northern Blotting结果显示,蚕卵粉可以加强糖尿病小鼠地超氧化物歧化酶基因(SOD)的mRNA的表达水平。上述结果进一步研究蚕卵粉的生理功能及其利用提供理论依据。

Abstract: Using the induced diabetic mice, the effects of the silkworm eggs power on the blood glucose, SOD and SOD mRNA expression in diabetic mice were studied. The results showed that the blood glucose decreased dramatically in diabetic mice after fed on diet containing 5% silkworm eggs power for 45 days, but no effect in normal mice. The superoxide dismutase (SOD) in the liver of diabetic mice was lower compared to the normal mice. When fed on 5% silkworm eggs power, the activity of superoxide dismutase increased again, almost reach to the normal level. The results both RT-PCR and Northern Blotting demonstrated that the mRNA of superoxide dismutase gene in diabetic mice develop to the normal level after fed on diet containing 5% silkworm eggs power for 45 days. The results construct the basis for further experiments of the function and amplification of silkworm eggs power.
