Table 5.

Permeation of ascorbic acid through freshly excised goat cornea (paired) from solution containing MAG (Na⁺–K⁺ ATPase inhibitor, 50 μmol) or Ouabain (Na⁺–K⁺ ATPase inhibitor, 1 mmol). Values are mean ± SEM of 3 corneas in each group.

Concentration (w/v)		Amount permeated (mg) (120 min)	Permeation (%) (120 min)	Corneal hydration (%)
1.0%	Control	0.087 ± 0.006	0.87	78.65 ± 1.46
	MAG∗	0.047 ± 0.003†	0.47	77.15 ± 1.52
1.0%	Control	0.11 ± 0.017	1.1	79.64 ± 1.34
	Quabain	0.066 ± 0.003†	0.66	75.69 ± 1.67

^†Statistically significant (P < 0.05) compared with solution without MAG or without Ouabain (control) as determined by paired t-test.
