Stimulatory effects of centrally injected nitric oxide donors on gastric acid secretion in anesthetized rats.
The effects of centrally injected nitric oxide (NO) donors on gastric acid secretion were investigated in continuously perfused stomach of anesthetized rats. The lateral cerebroventricular (LV) injection of NOC5 (30 - 100 microg) and NOC12 (10 - 100 microg) dose-dependently stimulated gastric acid secretion. The LV injection of NOC18 (30 microg) also stimulated gastric acid secretion. The other type of NO donor, sodium nitroprusside (3 - 30 microg, LV), also dose-dependently stimulated gastric acid secretion. The effect of NOC5 at 100 microg was blocked by carboxy-PTIO, an NO scavenger, and by cervical vagotomy. Furthermore, NOC12 (30, 100 microg) dose-dependently stimulated gastric acid secretion in pylorus-ligated conscious rats. These results suggest that centrally injected NO donors stimulate gastric acid secretion in both conscious and anesthetized rats through vagus activation.
