摘要
目的探讨热休克蛋白47(HSP47)在早期糖尿病大鼠的表达及意义。方法雄性Wistar大鼠30 只,随机分为糖尿病模型组(DR组,n=20)及正常对照组(对照组,n=10)。用链尿佐菌素(STZ)腹腔注射制作大鼠糖尿病(DM)模型。于模型建立后1月处死大鼠,取眼球做石蜡切片及视网膜铺片。用胰酶消化视网膜并行 PAS视网膜血管染色,观察管视网膜血管形态变化,用免疫组化法检测HSP47在视网膜的表达。结果正常大鼠视网膜HSP47染色为阴性,但在早期糖尿病大鼠视网膜HSP47染色均为阳性,而视网膜血管形态变化不明显。结论HSP47作为一种胶原特异的分子伴侣,在胶原装配、合成过程中起作用,早期糖尿病大鼠视网膜HSP47表达增加,可能是导致增生性糖尿病视网膜病变(PDR)发展的重要因素之一。
