【摘要】 <正> 老年性白内障为我国主要的可治致盲性眼病之一,其发病机制仍未明确。关于维生素C与老年性白内障的因果关系仍有争议。为了解房水维生素C含量与白内障的关系,作者惟就老年性白内障(简称“老白”)病人血与房水的维生素C进行检测,并与健康人(非白内障更多还原

【Abstract】 With 2, 4-dinitrophenylzide assay, we determined the content of blood and aqueous humor in senile cataract patients and healthy(noncataract) subjects。We found no significant difference(p>0.05) between the mean level(5.02±2.02mg%) of vitamin C of blood in senile cataract (53 cases) and 4.91±1.21mg% in healthy subjects(30 cases), but the vitamin C content (7.85±5.52mg%) of aqueous humor in senile cataract (31 cases) was more lower (p<0.05) than non-cataract (14.4+14.3 in 9 cases). It was also found that vitamin C content of 9 opaque (senile cataract) lens was 12.3±17.1mg% lower than that of 3 clear lens (21.3±9.88mg%). So it is presumed that there may be certain relationship between vitamin C content of aqueous humor and the pathogenesis of senile cataract.更多还原
