Propolis, a Constituent of Honey, Inhibits the Development of Sugar Cataracts and High-Glucose-Induced Reactive Oxygen Species in Rat Lenses

Figure 2

Effect of water soluble propolis on lens opacity in rats fed a high galactose diet. Rats in each group were given ad libitum access to 15% or 25% D-galactose mixed with regular chow, as well as being continued on 0.6 g/kg/day purified honey, 0.1 g/kg/day propolis, or 0.6 g/kg/day propolis, for 3 weeks. Control rats were allowed ad libitum access to regular chow, as well as being continued on 0.6 g/kg/day purified honey, for 3 weeks. Propolis suppressed lens opacity in rats fed (a) 15% and (b) 25% galactose. (c) Densitometry shows that oral intake of propolis (0.6 g/kg) significantly suppressed lens opacity in galactose-fed rats. Results shown are the mean ± SD of three experiments. Asterisks denote statistically significant differences. ; ; .
