Table 1. Effect of caffeine on levels of GSH and ATP in the lenses.

Groups	GSH (µmoles/g wet wt. of lens)	ATP (µmoles/g wet wt. of lens)
Control	6.15±0.15	1.3±0.05
Galactose	0.9±0.07*	1.0±0.055
Galactose + caffeine	5.01±0.05 **	1.35±0.005

Rats weighing 40–45 g were fed a 24% galactose diet with or without 1% caffeine. GSH was then determined in the TCA extracts of the tissue after its neutralization with Na₂HPO₄ and reacting it with DTNB reagent as described in the text. The values marked with an asterisk are significantly lower than the corresponding controls. The values marked with a double asterisk are significantly higher than those marked with an asterisk and are significantly closer to the controls, p<0.05, n=8 (number of animals).
