Isicelo
1. Endaweni ye-glacial acetic acid, isetyenziselwa ukudaya kunye nokugqiba inkqubo ye-acrylic. i-dacron, inayiloni kunye nolunye ucu lweMichiza, uboya. isilika kunye nezinye iifayibha zezilwanyana, umqhaphu. ilinen. Umsonto kunye nolunye ucwecwe lwezityalo, ukuprintwa kweWax, kunye nelaphu lokudibanisa.
2. Ukulungelelaniswa kwexabiso le-PH yazo zonke iintlobo ze-asidi pickling, i-dyeingbath (kubandakanywa nokuhlamba umbala), ukulungiswa kombala, ukugqiba i-resin njl.
3. Ukuvelisa ezinye iintlobo zedayi, ezifana ne-Benzidine Yellow G.
Inzuzo
Umsebenzi kunye nesiphumo zingcono kunezinye i-asidi yokudaya kunye ne-acetic acid.lt ayinamonakalo kwifayibha, kwibhafu yokudaya i-pHvalue iqinile.ayinayo i-acid fold fold, intlenga kunye neziphumo zamanzi aqinileyo, ukuphucula ukunyuswa kwedayi kunye nepropati yokudaya umgangatho. yezinye izinto zedayi, kwaye azinaziphumo ekukhanyeni okumibalabala okanye ukukhawulezisa kombala kweemveliso ezenziweyo.Ukongezelela, akukho vumba linukayo, akukho mkhenkce ebusika, kukhuselekile kwaye kulula ukuyisebenzisa.Umgaqo we-acetic acid endoscopy (AAC):

1. I-acetic acid inokutshabalalisa ibhondi ye-disulfide ye-glycoprotein kwi-gastric mucus layer kwaye i-depolymerize isakhiwo se-tetramer se-glycoprotein, okubangelwa yi-mucus encinci, ekulula ukuyihlamba kwaye idlala indima ekucoceni i-gastric mucosal surface.

2. I-acetic acid inokungena kwi-cytoplasm ngokusebenzisa i-membrane yeseli, yenza ixabiso le-pH kwi-cytoplasm lehla ukusuka kwi-7.0-7.4 ukuya kwi-6.5, i-cell keratin iphola ibe yimiqulu, iiseli ziba zikhulu, ukuhanjiswa kokukhanya kuyancipha, i-protein architecture ye-epithelial. iiseli zitshintshwa, kwaye iipropathi zeeseli ze-epithelial ziguqulwa ngokukhethiweyo. Yenza i-spatial structure ye-intracellular chromatin kunye ne-intracellular keratin kwi-cytoplasm utshintsho oludlulayo, igxininisa i-morphological structure ye-mucosal surface, kwaye emva koko igqamisa iiseli ze-columnar epithelial phantsi kwe-irradiation emhlophe, ivelise into emhlophe. Ngokomzekelo, ukunyanzeliswa kweeseli ze-epithelial kuyanda. I-acetic acid ingena ngokuyinxenye kwi-nucleus inokuphinda i-unhelix i-superhelix DNA kwaye iqinise umphumo wobumhlophe. Xa i-acetic acid yachithwa ngokuthe ngcembe yi-cytoplasm, isiphumo esingentla sanyamalala.

3. I-acetic acid inokufikelela kwi-interstitium nge-mucosa, okubangelwa ukuxinana kwe-capillary. Ngoko ke, emva kokutshiza i-acetic acid, i-mucosa iya kuba bomvu ngokuthe ngcembe emva kwemizuzu emi-2-3 yomhlophe. I-acetic acid spray yandisa ubuso beeseli ze-epithelial zezinto ezingabonakali, zinokugubungela inethiwekhi ye-vascular phantsi kwe-epithelium.

4. Ukuvulwa kwamadlala okanye i-crypts yenye yeendlela zokungeniswa kwe-acetic acid, eyandisa indawo ephezulu yeeseli ezivezwe kwi-acetic acid, kwaye yenza i-mucosa igxininise kwaye ibe mhlophe jikelele. Ubume be-concave buboniswa ngokucacileyo, kwaye ukumila kokuvula kwe-microglandular canal kunokubonwa ngokucacileyo.

5. Ubude be-mucosal whitening buhluka ngokwezinga lezilonda ze-mucosal kunye nokuhlukana kwe-tumor. I-mucosa eqhelekileyo inexesha elimhlophe elide (imizuzu eyi-1-2), ngelixa i-carcinoma eyahlukileyo okanye i-submucosal carcinoma inexesha elifutshane elimhlophe (imizuzwana eyi-3-10), kwaye umgca wokucanda wenziwa phakathi kwezicubu ezinomhlaza kunye nezicubu eziqhelekileyo ze-mucosal ezijikelezayo, ezichaza i-mucosal. Ubungakanani bezicubu ezinomhlaza. Ngapha koko, inokunceda ukwahlula kunye nokuchonga izilonda nge-microvascular atypia kunye ne-microstructure engacacanga yomphezulu phantsi kwe-endoscopy eqhelekileyo yokukhulisa, kwaye inokuphucula kakhulu izinga lokufunyanwa kwe-gastric mucosa kunye ne-metaplasia yamathumbu.
