Values are expressed as medians. The “+” represents the middle of that median. Median representation: 0, clear; 1, clear nucleus with wide sutures; 2, slight dense nucleus with opacities radiating from sutures; 3, dense nucleus without clefts; 4, dense nucleus with clefts; 5, nuclear cataract with clefts; 6, nuclear cataract with dense radial opacities; and 7, nuclear cataract with whole lens opacity. Note: ^ap=0.014 (group II compared with group VII on the fourth week); ^bp=0.043 (group III compared with group VII on the fourth week); ^cp<0.05 (the left eyes compared with the right ones in the lens opacity at week 6, 9, and 10 in group II); ^dp<0.05 (the left eyes compared with the right ones in the lens opacity at week 10 week in group III); ^ep<0.05 (the left eyes compared with the right ones in the lens opacity at week 6, 9, and 10 in group V); and ^fp<0.05 (the left eyes compared with the right ones in the lens opacity on the eighth week in group VI). L: the left eyes, which served as the treated eyes; R: the right eyes, which served as the control eyes. The number of lens (n) represents equally in both the left and right eyes in each group. Group I: Normal; Group II: Carnosine treated (5 mg/ml); Group III: Carnosine treated (10 mg/ml); Group IV: Aspirin treated; Group V: Aminoguanidine treated (1 mg/ml); Group VI: Aminoguanidine treated (2 mg/ml); and Group VII: Untreated diabetic.
