Hydrochloric acid esiswini: umsebenzi nencazelo

I uketshezi of juice esiswini Kwenzeka ngokusebenza komoya le mucosa esiswini. Kuyinto kungekho nto enemibala emihle, uketshezi ayinaphunga nge izigaxa elincane isikhwehlela. Noma yimuphi ukuphambuka kusuka kule evamile ezifana ekushintsheni umbala kanye kwabantu, bathi kukhona izinkinga kanye ipheshana emathunjini. Ukwakheka Inxanxathela we juice esiswini ngoba ukukhiqiza amaseli ahlukahlukene esiswini mucosal. ingxenye yayo oyinhloko hydrochloric acid, okuyinto yena, kuyahluka Ukwakheka kanzulu.

Ukwakheka juice esiswini

Ngaphezu hydrochloric acid kule juice esiswini siqukethe le izingxenye ezilandelayo

1. Bicarbonates (bona iwukudambisa mathonya alimazayo ka hydrochloric acid ogangeni esiswini).
2. Pepsinogen, kuphenduke pepsin (okokugcina waziphatha ukuwohloka amaprotheni). Pepsin ihlukaniswe yaba omunye umkhaya enzyme, ngamunye ephethe lwenza umsebenzi walo ohlukile.
3. Amafinyila (futhi ivikela mucosa ekubhujisweni).
4. Castle isici (-enzyme ekusiza ukuba ukwazi ukumunca _B12).

Nokho, isici esiyinhloko sokulawula juice esiswini namanje ngokunembile hydrochloric acid. On kuzoxoxwa.

Uyini hydrochloric acid?

Its umkhiqizo parientalnye amaseli nezindlala esiswini, esisogwini phansi emzimbeni nomzimba. Okusho ukuthi, ulwelwesi lwamafinyila ihlukaniswe yaba izingxenye eziningana: eyodwa ukhiqiza hydrochloric acid, kanye nezinye - ke inike bicarbonates zokuyithena. Kuyaphawuleka ukuthi amaseli amadoda parientalnyh izikhathi eziningana kunaleyo abesifazane.

Okuqukethwe nezinye acid esiswini kancane. Ngakho, uma kutholwa acidosis acid, kuthiwa i-hydrochloric acid ikhiqizwa nengcosana (pH eliphansi esiswini) noma hhayi kukhiqizwa nhlobo. Lesi sakamuva zingase zibe Indlela enjalo ukwehluleka sina njengoba Oncology.

Hydrochloric acid esiswini has a lokuhlushwa ezingeni eqinile - kuba 0.3-0.5% (noma 160 mmol / l). Ukwakheka kwalo kuyinto kanzulu ukuze ngaphandle juice esiswini futhi lwamafinyila ulwelwesi izinto zokuzivikela, bekuyoba zishe esiswini sakhe. Yingakho ukuntuleka esiswini isikhwehlela, umuntu has kolwelwesi noma isilonda duodenal. I acid likhona esiswini ngaso sonke isikhathi, kodwa eziphendula kokuthola ukudla kwandisa isibalo saso. uketshezi Basal ka hydrochloric acid (isb ekuseni) kuyinto 5-7 mmol / ihora.

esiswini Healthy ukhiqiza kuze kufinyelele 2.5 amalitha hydrochloric acid ngosuku!

Uketshezi of hydrochloric acid has 3 izigaba.

1. I yokusabela kuya zokunambitha nokuhogela ukudla. Ingabe yaqala futhi idluliselwa kusuka CNS ku amaseli esiswini ngokusebenzisa eziyimpumelelo emsipheni.
2. Ngemva ukushaya ukudla emzimbeni phezu isigaba esikhulu siqala. Gastrin enza parientalnye amaseli by inkanuko ukukhiqizwa hydrochloric acid.
3. Isigaba sokugcina luqala ngemva ukushaya chyme (ukudla kakade kugaywe) phakathi duodenum. Ngenxa yokwanda esiswini hydrochloric acid ukhiqiza somatostatin - blocker yayo.

Yini imisebenzi wenza hydrochloric acid esiswini?

Okokuqala, it ngcono ukugaya, obulala amagciwane kakhulu ufaka ukudla esiswini, okuyinto kubambezela noma evimbela elibi.

Yiziphi imisebenzi hydrochloric acid esiswini? Ngezansi uhlu imininingwane okwembula ukuthi umbuzo.

• Denaturation we amaprotheni (lokhu ukubhujiswa isakhiwo sabo yamangqamuzana) nokuvuvukala yabo.
• Ukwenza kusebenze pepsinogen, okuyinto ibe pepsin - omunye wemizila ebaluleke kakhulu enzyme ukuthi sokudiliza amaprotheni.
• Ukwakha isimo esidi lapho nemibandela ukugayeka enzymatic kuba lula.
• Kuhlengwe ukudla kusukela esiswini phakathi duodenum, lapho ukugaya uyaqhubeka.
• isenzo elwa namagciwane - amagciwane amaningi awukwazi bahlala enjalo endaweni enobudlova.
• I excitation we uketshezi juice pancreatic.

Ngokukhethekile kufanele anikezwe indima hydrochloric acid kule cleavage amaprotheni. Meaning of amaprotheni emzimbeni nawo njengomnyango mkhulu kakhulu. Lo mbuzo ibilokhu wafunda ososayensi amashumi eminyaka. Litholakala ukuthi hydrochloric acid esiswini ezizokhuthaza ukukhiqizwa kwamangqamuzana pepsin, ukudala indawo evumayo umsebenzi wayo, ikhuthaza ukuvuvukala kanye denaturation ngokwengxenye amaprotheni. Esikhathini duodenum hydrochloric acid secretin kuvusa, sithuthukisa ukumuncwa zensimbi kunomphumela amagciwane.

Amaphrotheni kanye asidi esiswini

Indima hydrochloric acid ku ukugaya of amaprotheni ngenkathi nalapho. Nokho-ke yathola ukuthi izifo sokuvuvukala uketshezi isisu yayo ngobugebengu ngenxa yalokho, ukugaya of amaprotheni.

Meaning of amaprotheni emzimbeni babenesibindi esikhulu. Leli qembu ihlukaniswe subgroups eziningi, ngasinye sazo wahlanganyela ibhizinisi. Ngakho, amaprotheni hormone ukulawula izinqubo ezibalulekile (ukukhula reproduction), amaphrotheni, ama-enzyme ukunikeza amakhemikhali izinqubo (emishinini yokuphefumula, ukugaya, umzimba), i-hemoglobin oxygenates amaseli.

Denaturation amaprotheni (kusiza inqubo eqhekeza okwalandela) uvumela umzimba ukusebenzisa esiphezulu izakhiwo zabo. amaprotheni ngasinye siqukethe amino acid. Iningi lawo kuhlelwe umqondo ngu umzimba, kodwa kukhona iqembu okuthiwa acid ezibalulekile acid ukuthi ufake umzimba kusukela ngaphandle kuphela.

I-asidi we juice esiswini

isici okunjalo kubalulekile, pH esiswini incike hydrochloric acid. Futhi uma kukhona ukuphambuka kusuka kuyinsakavukela, kukhona kolwelwesi, dyspepsia nezinye izimo ezingezinhle. Asidi esiswini kungancipha, evamile noma aphakeme.

Naphezu "udumo" ka-pH yanda, ngokuvamile abantu aye ancipha noma asidi evamile. Lesi sakamuva kusukela 0.8 1.5.

Encishisiwe asidi esiswini

asidi okuphansi kwenzeka ngesikhathi ukucindezeleka njalo futhi Izifo ukuvuvukala. Lokhu kwenzeka ngenxa excitation kohlelo nozwela sezinzwa, esithinta ngqo ukukhiqizwa of juice esiswini. Wehlise asidi eziwohlokayo ukudla ukugaya kanye esiswini amajaqamba. Ukudla uhlala ngaphakathi komgodi iqala ukubola, okwandisa Lokusakaza namagciwane abangela izifo. Le ndoda wayehlushwa ukubuyisa nesicanucanu. Lesi sakamuva aphendula spasm isisu. Ngaphezu kwalokho, ngenkuthalo ahlahlele inqubo ukumuncwa kwezakhi eziqukethwe ukudla kwethu, okuholela ukuphazamiseka wonke umzimba. By the way, ngesisekelo ukwehla zemvelo e-pH ngemva kweminyaka engu-40, umuntu uqala ubudala ngokushesha. Okungukuthi, abangabantwana hydrochloric acid esiswini empeleni kabi impilo yonke umzimba.

Isisu, overgrowth bamangale-bacterium zihlanganisa umsebenzi zokuzivikela iqala, okubangela ukuvuvukala livela. It ziphathwe izidakamizwa ukuthi zivimbela ukukhiqizwa obengeziwe hydrochloric acid - kanye umbuthano ivaliwe. Man njalo ophoqelelwe ukuvakashela udokotela.

Ngisho isilungulela, okuyinto thina esetshenziswa ukuthatha umphumela ukukhulisa inani juice esiswini ubhekwa umkhiqizo acetic acid ukuvutshelwa.

In iziguli esiswini iyaqala ngenkuthalo kwakhiwa acidosis acid. Ngenxa ukungakwazi esiswini ukukhiqiza isikhwehlela ngokwanele, umonakalo odongeni umzimba. Ezimweni ezinjalo kwatholakala ukuthi unesifo - gastro.

Izimuncagazi futhi enciphile asidi esiswini

Encwadini esiswini okunempilo hhayi izimuncagazi bangaphila (nakuba lokho akuvimbeli kwasendaweni yabo kwezinye kwezitho izinhlelo zomzimba), njengoba ngokoqobo burns hydrochloric acid. Kodwa ngokushesha lapho lehla eziwuhlupho amakoloni uqale ukuba uchume, okubangela izimpawu kubuhlungu ngempela. Ngisho ngaphezulu okhathazekile ukumuncwa kwezakhi, kukhona ingozi engezwani nokudla okuthile (uma izimuncagazi "akakuthandanga" Yidla ukudla).

asidi Ukwandiswa isisu

Naphezu umbono gastroenterologists eziningi, hyperacidity is lingandile kangako encishisiwe. Ingozi iba ukuthi ngesikhathi hypersecretion isikhathi eside of juice esiswini, kukhona izilonda we emphinjeni nasesiswini. Iziguli ukhathazekile isilungulela ubuhlungu. Kukhona nje kuyoba usizo proton futha inhibitor - "Omez" futhi analogue yayo. Izimpawu esebenzisa antacids - "Gaviscone", "Fosfalyugel" et al.

Ukuxilonga asidi ngempela isicelo luhlolo wezinsimbi, ngenxa yezimpawu zalo udidekile kalula kwehle uketshezi.

Amafomu ukucacisa asidi we esiswini

Hydrochloric acid esiswini (ngamanye amazwi, ezingeni) inqunywa izindlela eziningana.

1. Eqonda. Kwenziwa kusetshenziswa tube ekhethekile, okuqukethwe lapho esiswini ukusivumela.
2. Intragastric pH-metry. Izinzwa ulinganise asidi esiswini ngqo.

Eyesibili indlela kubhekwa ulwazi kakhulu.

I-asidi we esiswini - lena yinto okungahambisani banake odokotela abaningi, kodwa eqinisweni kubaluleke kakhulu ukuze kuhlonzwe kanye nokwelashwa izifo emathunjini.
