对人眼房水内维生素C的含量在国内外均已有报导,但维生素C在人晶体内的分布与含量则报导较鲜。为探讨不同发育时期人晶体内维生素C的变化情况,我们应用显示晶体内维生素C的组织化学方法,对不同胎龄的胎儿晶体内维生素C的含量与分布进行了初步研究。材料与方法取产后窒息或自愿人流的正常人胎眼新鲜晶体12例。其中2个月胎儿晶体2例,4个月2例,6个月2例,7个月1例,8个 The content of vitamin C in human aqueous humor has been reported at home and abroad, but the distribution and content of vitamin C in human crystal are reported relatively fresh. To investigate the changes of vitamin C in human lens at different developmental stages, we studied the content and distribution of vitamin C in fetal lens of different gestational age by using the histochemical method of vitamin C in the lens. Materials and Methods Twelve patients with normal fresh eye fetus underwent asphyxiation or voluntary abortion after delivery. 2 months fetus crystal in 2 cases, 4 months in 2 cases, 6 months in 2 cases, 7 months in 1 case, 8 months
