Zehydrochloric acid esiswini: umsebenzi nentsingiselo

Le secretion yesiselo esiswini Oku kwenzeka ngokuthi ukusebenza isifo esiswini. It is a ezingenambala ulwelo, esha kunye engenamaqhuma ezincinane yencindi yomlomo. Nakuphi na ukutenxa kule mmiselo, ezifana ukutshintsha umbala nokuxinana, bathi ukuba kukho iingxaki kunye iphecana zesisu. nokwakheka Complex yencindi yewayini esiswini ukusukela uvelise iiseli ezahlukeneyo esiswini mucosal. inxalenye yalo esentloko kukuba zehydrochloric acid, mvisiswano leyo, kwelinye icala, iyahluka kuqamba wamandla.

Ukubunjwa ijusi esiswini

Ukongeza zehydrochloric acid kwincindi esiswini sinezi zixhobo zilandelayo

1. Bicarbonates (bona Nokwethisa iziphumo zomonakalo zehydrochloric acid eludongeni isisu).
2. Pepsinogen, ajike abe pepsin (le yokugqibela ibandakanyeka yokuwa iiprothini). Pepsin wohlulwe kolunye usapho enqanda, nganye eneyazo umsebenzi walo.
3. Yencindi yomlomo (it kwakhona sikhusela isifo ekutshatyalalisweni).
4. Castle factor (enzayimi kuyanceda ukufunxa _B12).

Noko ke, enye yezinto ezibalulekileyo juice esiswini isekhona kanye zehydrochloric acid. On kuya kuxoxwa.

Yintoni zehydrochloric acid?

Its iiseli imveliso parientalnye kwamadlala esiswini, ibekwe kwi ezantsi umzimba umzimba. Enyanisweni, i-inwebu yangaphakathi yohlulwe imimandla eliqela: omnye kuvelisa zehydrochloric acid, kwaye enye - loo yabela bicarbonates lwaze. Ibangel 'umdla into yokuba iiseli amadoda parientalnyh na izihlandlo ezininzi ngaphezulu kwabasetyhini.

Umxholo we nezinye ii-asidi esiswini kancinci. Ngoko ke, ukuba ngaba ufunyaniswe lactic acid, kuthiwa ukuba zehydrochloric acid lukhutshwe ngezixa ezincinane (pH ephantsi esiswini) okanye hayi yaveliswa kwaphela. Le yokugqibela kusenokuba kubonisa lokungaphumeleli ezinkulu ezifana Oncology.

Zehydrochloric acid esiswini na inqanaba olomeleleyo yoxinaniso - kuba 0.3-0.5% (okanye 160 mmol / l). ukwakheka layo kanzulu kangangokuba ngaphandle incindi esiswini kunye inwebu izinto yangaphakathi yokhuselo, bekuya ecima esiswini sakhe. Kungenxa yoko le nto kukunqongophala isisu yencindi, umntu gastritis okanye isilonda duodenal. Le asidi ekhoyo esiswini lonke ixesha, kodwa ekhawulelana kokufumana ukutya kwandisa inani layo. secretion carcinoma of zehydrochloric acid (ngamanye kusasa) yi 5-7 mmol / hr.

nesisu enempilo ivelisa ukuya iilitha 2.5 zehydrochloric acid ngosuku!

Secretion of zehydrochloric acid lunezigaba 3.

1. Zasabela incasa kunye nevumba ukutya. Iqalisile yaye isasazeka ukusuka CNS kwiiseli esiswini ngenxa kwalapho.
2. Emva kokuthumela ukutya emzimbeni phezu kwisigaba enkulu iqala. Gastrin enza iiseli parientalnye ngokuvuselela imveliso zehydrochloric acid.
3. Isigaba sokugqibela iqala emva embetha chyme (ukutya sele zifunxe) kungena duodenum. Ngenxa yokwanda isisu zehydrochloric acid uvelisa somatostatin - blocker yayo.

Yiyiphi imisebenzi wenza zehydrochloric acid esiswini?

Okokuqala, oko ngcono ukugaya, ibulala ezininzi iintsholongwane ukuba ufake ukutya esiswini, nto leyo ebizwa ngokuba yimetabolism isenokucotha okanye kuvimba ukubola.

Yiyiphi imisebenzi zehydrochloric acid esiswini? Ezantsi apha kukho uluhlu lweenkcukacha ukuveza lo mbuzo.

• Nokuguqulwa of iiproteni (oku ukutshatyalaliswa yesakhiwo ezinto) kunye ukudumba kwazo.
• Ukusebenza pepsinogen, nto leyo iguqulelwa zibe pepsin - enye yezinto ezibalulekileyo enzayim ndoyidiliza iiprothini.
• Ukudala imeko asidi apho imiqathango ukwetyisa enzymatic kulula kakhulu.
• Ngobungxamo ukutya ukusuka esiswini kulo duodenum, apho ekugayeni uyaqhubeka.
• inyathelo Antibacterial - iintsholongwane ezininzi abakwazi phila kwindawo ndlongondlongo ezinjalo.
• Le excitation le secretion yejusi pancreatic.

ingqalelo ekhethekileyo kufuneka anikwe indima zehydrochloric acid kwi cleavage of iiprothini. Meaning of iiproteni umzimba kakhulu. Lo mbuzo uye wafundela zizazinzulu eminyaka. Kufumaniseka ukuba asidi zehydrochloric esiswini lukwakhuthaza ukuveliswa pepsin, ukudala indawo evumayo umsebenzi wayo, ekhuthaza ukudumba kunye nokuguqulwa kwenxenye iiprothini. Kule duodenum kushukumisa acid secretin zehydrochloric, iphucula kukufakwa yesinyithi kwaye kunempembelelo bactericidal.

Ngeeproteni asidi esiswini

Indima zehydrochloric acid kwi ukwetyisa kweziyi ngelixa nalapho. Kambe ke ndafumanisa ukuba izifo yokukrala secretion nesisu kunye bayo okunene baphuke ngenxa yoko, ukwetyisa kweziyi.

Meaning of neeproteni emzimbeni kakhulu. Eli qela yahlulwe subgroups ezininzi, nganye kuzo inxaxheba kwishishini. Ngenxa yoko, iiprotheni iihomoni ilawula iinkqubo ebalulekileyo (ukukhula nokukotshwa), iiprotheni, enzayim zinika iinkqubo imichiza (yokuphefumla, ukwetyisa, ukutya), ihemoglobin oxygenates iiseli.

Nokuguqulwa kweziyi (kube lula inkqubo kukwahlukana elandelayo) uvumela umzimba ukusebenzisa ubuninzi iipropati zabo. protein ngalinye lenziwa asidi acid. Abaninzi babo kuhlelwe yi umzimba, kodwa kukho iqela ebizwa ngokuba yi-asidi kubalulekile acid ngenisa umzimba ngaphandle kuphela.

Le asidi ijusi esiswini

Onjalo umba obalulekileyo, i-pH esiswini ixhomekeke zehydrochloric acid. Kwaye ukuba kukho ukutenxa kumgaqo, kukho gastritis, ukuqunjelwa kunye nezinye iimeko ezingemnandi. Asidi esiswini inokuba kuncitshiswa, eqhelekileyo okanye buyobe.

Nangona "ukuthandwa" eyandileyo pH, ngokufuthi abantu ziye zancitshiswa okanye iasidi eziqhelekileyo. Le yokugqibela ivela 0.8 ukuya 1.5.

Ukuncipha asidi esiswini

asidi Low kwenzeka xa uxinezeleko rhoqo kunye nezifo arhabaxa. Oku kwenzeka ngenxa yokuba excitation kwenkqubo onovelwano luvo, nto leyo echaphazela ngqo imveliso incindi esiswini. Ukwehlisa asidi emandundu le ukwetyisa ukutya kunye nesisu amahlaba. Ukutya uhlala em- uqalisa ukubola, ukwandisa andise iintsholongwane izifo. Le ndoda enesifo flatulence kunye isicaphucaphu. Le yokugqibela yi uphefumla spasm esiswini. Ngaphezu koko, ngenkuthalo uyazifohloza inkqubo nokufunxwa izondlo equlethwe ukutya yethu, nto leyo ekhokelela ukuphazamiseka umzimba wonke. Hi ndlela leyi, ngokusekelwe kukuhla zendalo kule pH emva kweminyaka engama-40, umntu uqalisa Ubudala ngokukhawuleza. Oko kukuthi, eneneni asidi zehydrochloric esiswini na ezichaphazela impilo yonke eziphilayo.

Isisu, imithana ukumangaliswa iintsholongwane ziquka zikhusela luqala, ebangela ukudumba ibonakala. Ithathwa kunye iziyobisi zinqanda imveliso ngakumbi zehydrochloric acid - kwaye isangqa ivaliwe. Man rhoqo ukuba ukutyelela ugqirha.

Nokuba heartburn, leyo sasidla ukuthatha isiphumo yokwandisa ubungakanani yejusi esiswini kuthathwa ukuba ibe yimveliso acetic acid ukubila.

Xa izigulane esiswini uqalisa ngenkuthalo ukusekwa lactic acid. Ngenxa yokuba ukungakwazi isisu ukuvelisa yencindi ngokwaneleyo, oko konakalisa udonga umzimba. Kwiimeko ezinjalo une - gastro.

Nazirhorho nokuphungulwa iasidi esiswini

Xa isisu esempilweni izilwanyana kuphila (a nangona oku ngaphandle kwasendaweni yabo kwamanye amaziko kunye neenkqubo zomzimba), njengoko ngokoqobo utshisa zehydrochloric acid. Kodwa kamsinya nje tsakisi, amakhalane amathanga baqala omfuphi, ebangela iimpawu zingambi kakhulu. Nkqu ephazanyiswe ngakumbi nokufunxwa izondlo, kukho umngcipheko komzimba ukutya (ukuba gazi "akazange nje" Yitya ukutya).

iasidi Ukwanda esiswini

Nangona uluvo gastroenterologists ezininzi, hyperacidity kakhulu luphela ebantwini lifinyele. Ingozi kukuba ngexesha hypersecretion elide juice esiswini, kukho nezilonda le kuvuleke iminxunya emathunjini. Izigulane ochaphazelekayo malunga heartburn kunye neentlungu. Kukho nje kuya kuba luncedo pump Proton inhibitors - "Omez" kunye analogue yayo. Okudambisa iimpawu ngokusebenzisa asidi - "Gaviscone", "Fosfalyugel" et al.

Ukuxilonga asidi isicelo ngokuyimfuneko uviwo instrumental, ngenxa iimpawu zayo badidekile lula yehle secretion.

Forms amisele asidi esiswini

Zehydrochloric acid esiswini (ngamanye amazwi, inqanaba) umiselwa ngeendlela ezininzi.

1. Axakekile. Kwenziwa ngokusebenzisa ityhubhu ezizodwa, apho iziqulatho isisu owawanyayo.
2. Intragastric pH-metry. Abenzi boluvo umlinganiselo asidi esiswini ngqo.

Indlela yesibini ithathwa kakhulu ulwazi.

Le asidi esiswini - oku yinto loo nto batyekayo ekumlandeleni, Abaziqiqa oogqirha, kodwa enyanisweni kubaluleke kakhulu ukuba afunyaniswe isifo kwaye afumane unyango lwezifo zesisu.
