Syringic Acid Extracted from Herba dendrobii Prevents Diabetic Cataract Pathogenesis by Inhibiting Aldose Reductase Activity
Figure 2
Representative photographs of the lenses of rats in different groups showing the effect of syringic acid on cataract in vivo (×4). (a) Control group; (b) Model group; (c) Catalin group; (d) syringic acid group. In the normal control group, lenses remained transparent. In the model group, cataracts persisted even after intraperitoneal injection of syringic acid and oral administration of D-gal had stopped (Day 90). The syringic acid groups performed better than the Catalin group, with lens turbidity reduced to Grade I or Grade 0.
