Table 2. The effect of curcumin and nanocurcumin on aldose reductase (AR) activity and sorbitol levels in rat lens.

Groups	AR	Sorbitol
Control	52.93 ± 5.14	0.318 ± 0.060 ^a
Diabetic (D)	56.29 ± 3.79	2.671 ± 0.311^b
D + Curcumin	53.46 ± 12.75	2.178 ± 0.162 ^c
D + Nanocurcumin	50.65 ± 4.21	1.589 ± 0.141 ^d
D + Blank particles	56.12 ± 14.77	2.442 ± 0.102 ^e
	p=0.938	p=0.000

The data are mean ± SD (n=4). Different superscripts ^{a, b, c, d, e}) indicate data are significantly different from other groups. AR activity is expressed as µ moles NADPH oxidized/h/100 mg protein and sorbitol levels as µ moles/g lens.
