Values are expressed as medians. Median representation: 0, clear; 1, clear nuclear with wide sutures; 2, slight dense nuclear with opacities radiating from sutures; 3, dense nuclear without clefts; 4, dense nuclear with clefts; 5, nuclear cataract with clefts; 6, nuclear cataract with dense radial opacities; and 7, nuclear cataract with whole lens opacities. Statistical analyses were performed by using Wilcoxon rank sum test. Note: The asterisk denotes that p=0.023 (group II compared with group V on the fourth week). The asterisk denotes that p=0.031 (group IV compared with group V on the fourth week). Group I: normal; II: NAC-treated (0.1 mg/ml); III: NAC-treated (0.5 mg/ml); IV: GSH-EE-treated (1 mg/ml); V: untreated diabetic.
