Adaptive cytoprotection through modulation of nitric oxide in ethanol-evoked gastritis

Table 4 Effect of mild irritants and/or 50% ethanol on superoxide dismutase (SOD) activity in gastric mucosa of normal and gastritis rats

	SOD activity (units/mg protein)
	H2O	200 mL/L EtOH	50 g/L NaCl	0.3 mol/L HCl
Basal normal	32.08 ± 2.20	36.07 ± 3.18	38.01 ± 1.55	37.53 ± 3.06
500 mL/L EtOH normal	37.20 ± 2.51	41.14 ± 1.82	40.48 ± 0.99	41.33 ± 3.78
Basal gastritis	41.92 ± 2.42a	47.51 ± 3.27a	48.03 ± 2.06b	50.56 ± 3.88a
500 mL/L EtOH gastritis	50.85 ± 4.46a	49.76 ± 3.36a	57.68 ± 6.04a	54.92 ± 4.74a

Values are mean ± SE (n = 6),

^aP < 0.05,

^bP < 0.01 vs corresponding group without gastritis (Normal).
