1. Acetic acid nwere ike ibibi njikọ disulfide nke glycoprotein n'ime oyi akwa gastric mucus na depolymerize usoro tetramer nke glycoprotein, na-eme ka imi dị ntakịrị, nke dị mfe ịsacha ma na-ekere òkè na ihicha elu mucosal gastric.

2. Acetic acid nwere ike ịbanye na cytoplasm site na akpụkpọ ahụ cell, na-eme ka uru pH dị na cytoplasm na-agbada site na 7.0-7.4 ruo 6.5, cell keratin polymerizes n'ime ngwugwu, mkpụrụ ndụ na-abawanye ụba, nnyefe ọkụ na-ebelata, nhazi protein nke epithelial. a na-agbanwe mkpụrụ ndụ, a na-ahọrọkwa ihe onwunwe nke mkpụrụ ndụ epithelial. Ọ na-eme ka oghere oghere nke chromatin intracellular na intracellular keratin na cytoplasm mgbanwe mgbanwe na-adịru nwa oge, na-akọwapụta usoro morphological nke elu mucosal, wee pụta ìhè sel epithelial columnar n'okpuru ọkụ ọkụ na-acha ọcha, na-emepụta ihe na-acha ọcha. Dịka ọmụmaatụ, permeability nke mkpụrụ ndụ epithelial na-abawanye. Acid acetic nke na-abanye n'ime oghere n'ime oghere nwekwara ike iwepụ DNA superhelix ma mee ka mmetụta ọcha dị ike. Mgbe cytoplasm ji nwayọọ nwayọọ wepụ acetic acid, mmetụta ahụ dị n'elu kwụsịrị.

3. Acetic acid nwere ike iru interstitium site na mucosa, na-akpata nkwụsị nke capillary. Ya mere, mgbe ịgbasa acetic acid, mucosa ga-eji nwayọọ nwayọọ na-acha uhie uhie mgbe nkeji 2-3 gachara. Ihe nkedo acetic acid na-abawanye elu nke mkpụrụ ndụ epithelial nke ihe na-adịghị atụgharị uche, nwere ike kpuchie netwọk vaskụla n'okpuru epithelium.

4. Mmeghe nke glands ma ọ bụ crypts bụ otu n'ime ọwa maka infiltration acetic acid, nke na-eme ka akụkụ elu nke mkpụrụ ndụ ekpughere na acetic acid, na-eme ka mucosa na-agbapụta ma na-acha ọcha n'ozuzu ya. A na-egosipụta ọdịdị concave nke ọma, a pụkwara ịhụ ọdịdị oghere nke ọwa mmiri microglandular nke ọma.

5. Ogologo oge nke ọcha mucosal na-adịgasị iche dịka ogo nke ọnyá mucosal na ọdịiche dị iche iche nke ụbụrụ. Nkịtị mucosa nwere ogologo oge ọcha (1-2 nkeji), ebe carcinoma dị iche ma ọ bụ submucosal nwere obere oge ọcha (3-10 sekọnd), a na-emepụta ahịrị n'etiti anụ ahụ na-egbu egbu na anụ ahụ mucosal nkịtị gbara ya gburugburu, na-akọwapụta oke nke anụ ahụ cancer. Ọzọkwa, ọ nwere ike inye aka ịmata ọdịiche na ịchọpụta ọnya na microvascular atypia na edoghị anya n'elu microstructure n'okpuru nkịtị magnification endoscopy, na nwekwara ike budata mma chọpụtara ọnụego nke gastric mucosa na intestinal metaplasia.
