Pepsinogen bụ protease precursor nke mucosa gastric zoro ezo, enwere ike kewaa ya ụzọ abụọ: PG I na PG II.PG I bụ isi mkpụrụ ndụ nke fundus glands na cervical mucus cell na-ezobe PG II site na fundus glands, pyloric glands, na Brunner glands.Ọtụtụ n'ime PG synthesized na-abanye n'ime oghere afọ ma na-arụ ọrụ na pepsin n'okpuru ọrụ nke gastric acid.Ọtụtụ mgbe, ihe dị ka 1% nke PG nwere ike ịbanye na mgbasa ọbara site na mucosa gastric, na ntinye nke PG n'ime ọbara na-egosipụta ọkwa nzuzo ya.PG I bụ ihe na-egosi ọrụ nke mkpụrụ ndụ oxyntic gland gastric.Mmụba nke acid gastric acid na-abawanye PG I, na-ebelata ihe nzuzo ma ọ bụ na-ebelata atrophy gastric mucosal gland;PG II nwere mmekọrịta ka ukwuu na ọnya mucosal gastric fundus mucosal (tụnyere mucosa nke antral gastric).Elu metụtara atrophy fundus gland, gastric epithelial metaplasia ma ọ bụ pseudopyloric gland metaplasia, na dysplasia;na usoro nke fundus gland mucosal atrophy, ọnụ ọgụgụ nke isi mkpụrụ ndụ zoro ezo PG I na-ebelata na ọnụ ọgụgụ nke pyloric gland cell na-abawanye, na-akpata PG I The / PG II ratio mbelata.Ya mere, PG I/PG II ratio nwere ike iji dị ka ihe na-egosi gastric fundic gland mucosal atrophy.
