Tha anti-ulcerogenic mechanism of 2-(E-2-decenoylamino)ethyl 2-(cyclohexylethyl) sulfide (compd. III-1a) was investigated in various gastric defensive factors. Compound III-1a maintained the high molecular glycoprotein (relative content of Fr. I hexose) and accelerated hexosamine synthesis which were reduced by water immersion stress. But plaunotol did not have these actions. The lipid peroxide level in the gastric mucosa from water immersion stressed rat was lowered by the adiministration of compd. III-1a. Compound III-1a maintained prostaglandin E_2 (PGE_2) and PGI_2 contents which were reduced in the early phases of the stress and accelerated PGs synethesis in the late phase of the stress. Furthermore, compd. III-1a maintained phospholipase A_2 (PLA_2) activity which was reduced by the stress. The plaunotol treated group showed the same tendency as the compd. III-1a treated group on the lipid on the lipid peroxide level, PGE_2 and PGI_2 contents, and PLA_2 activity, but the potency of plaunotol was less than that of compd. III-1a. Compound III-1a accelerated gastric cell proliferation in pyloric glands of hydrocortisone treated rats. Tetragastrin accelerated significantly the cell proliferation in fundic glands. The sucralfate treated group showed the same tendency as the compd. III-1a treated group but the potency of sucralfate was less than that of compd. III-1a. The results in the present study suggest that compd. III-1a has a protective action on gastric mucosa.
