Figure 2. Effect of microemulsion formulation of tocotrienol (TTE) in various concentrations on the opacity index of galactose-fed rats during 4 weeks of treatment. All values are mean ± standard deviation (SD; n = 18). ^ap<0.001 versus normal; ^bp<0.01 versus vehicle; ^cp<0.05 versus 0.2% tocotrienol (TTE); ^dp<0.05 versus 0.1% TTE; ^ep<0.05 versus 0.05% TTE, ^fp<0.05 versus 0.02% TTE, ^gp<0.05 versus 0.01% TTE.
