title: Comparative studies on starvation - and indomethacin - induced ulcerations in albino rats.
abstract: Experimental models of chronic and acute peptic ulcerations were produced in the albino rats by means of prolonged starvation and indomethacin administration. In the case of acute indomethacin-induced peptic ulceration, the effects of anticholinergic drugs on the ulcers produced were also studied. Starving the rats for a period of seven days produced gastric ulceration in all the rats used while indomethacin produced gastric ulceration within five hours in all the rats used. Severe ulceration of the degree found in human peptic ulcer disease was produced only by chronic starvation. Anticholinergic drugs ameliorated indomethacin-induced gastric ulceration, partly at least, by reducing intra-gastric acidity.
