中文摘要:

以ICR小鼠为实验对象,注射180 mg/kg剂量链脲佐菌素构建糖尿病小鼠模型,利用苏木精-伊红染色法及免疫组织化学方法分析了糖尿病小鼠味蕾形态变化和味觉信号转导相关蛋白表达变化。结果表明,对照组小鼠与糖尿病组小鼠轮廓状乳头大小及数量无显著差异;但糖尿病小鼠单个味蕾中味觉信号转导蛋白α-gustducin及磷酸脂酶Cβ2的阳性细胞数显著增加(P

英文摘要:

Diabetes mellitus(DM) are induced in ICR mice with the dose of 180 mg/kg of streptozotocin(STZ) and then the morphological changes and the expression related with taste signal transduction of taste buds in vallate papillae are evaluated by hematoxylin-eosin staining and immune-histochemical methods.The results show that the number and the size of taste buds have no significant difference between control and DM mice.Whereas,compared with control mice,the DM mice have more number of α-gustducin and phospholipase Cβ2 positive cells per taste bud(P
