Aldose reductase (AR) is involved in initiation of galactosemic cataract in rats. AR inhibitors may prevent and reverse the cataract. FR74366, a new AR inhibitor, was shown to be of value in prevent-ing and inducing regression of galactosemic cata-ract in rats when fed in concentrations of 0.025% or 0.075%. We employed the proton nuclear magnetic resonance, 1H-NMR, in quantitating the cataract, or turgence of the crystalline lens, in 250 male rats fed with either of 7 types of food containing normal diet, galactose and/or FR74366 in various concen-trations. The findings indicated that 1H-NMR is of value in quantitating the degree of lens opacity in galactosemic cataract.
