Ngaba wakha watya isidlo esinamafutha amaninzi, njenge-biryani, okanye into efana ne-curry eqholiweyo enobisi lwekhokhonathi, okanye iqhekeza lentlanzi enamafutha? Xa ugqiba ukutya, ucinga, "Owu, kwanele, isisu sam sigcwele." Ngaba wakha wazibuza ukuba ngubani kanye kanye oxelela ingqondo yakho ukuba isisu sakho sigcwele kwaye kufuneka uyeke ukutya? Omnye wemisebenzi ebaluleke kakhulu yale hormone esithetha ngayo namhlanje yi-cholecystokinin. Ngamafutshane, ifana nomphathi obaluleke kakhulu kwinkqubo yethu yokugaya ukutya.
Ngamafutshane, yintoni i-cholecystokinin?
I-Cholecystokinin yi -hormone esebenza njengenxalenye yenkqubo yethu yokugaya ukutya. I-hormone sisithunywa sekhemikhali esiveliswa kwindawo enye emzimbeni wethu, sihamba ngegazi, size sithwale umyalezo kwenye indawo. Njengomntu othumelayo. Le cholecystokinin, okanye i-CCK ngamafutshane, ikhutshwa ngumzimba wethu emva kokuba sityile, xa ukutya kugayiwe.
Iveliswa kwaye ikhutshwa kakhulu emathunjini ethu amancinci . Kodwa into emangalisayo kukuba, le hormone ye-CCK ikwakho nakwingqondo yethu nakwinkqubo yethu yemithambo-luvo ephakathi. Kodwa oogqirha basazama ukufumana okuninzi malunga nomsebenzi wayo apho. Ngamanye amaxesha ikwabizwa ngokuba yi -pancreozymin . Kodwa igama eliqhelekileyo elisetyenziswayo yi-cholecystokinin.
Iqala njani ukukhutshwa le hormone ye-CCK emzimbeni?
Khawuthelekelele utya ukutya. Oko kutya kuqala kungena esiswini. Emva kokugaya ukutya esiswini, oko kutya kungena kwinxalenye yokuqala yamathumbu amancinci. Siyibiza ngokuba yi-duodenum .
Kulapho ke umsebenzi wokwenene uqala khona. Ukuba utye ukutya okutyebileyo kwiproteni (umz. inyama, intlanzi, amaqanda, iilentili) kunye namafutha (umz. ioyile, ubisi lwekhokhonathi, ibhotolo), uhlobo oluthile lweseli eludongeni lwe-duodenum (olubizwa ngokuba yi-'I-cells') "luyazazi" ezi proteni kunye namafutha. Kufana nomlindi obona undwendwe olukhethekileyo.
Xa zifumanisa iiproteni namafutha ngale ndlela, ezi seli zikhawuleza zivelise i-hormone i-CCK zize ziyikhuphele egazini lethu. Loo 'ngumqondiso' wokuba i-CCK iqale ukusebenza.
Ziziphi izinto eziphambili ezenzeka emzimbeni ngenxa ye-CCK hormone?
Xa i-CCK isegazini, ayihlali nje apho. Ifana nomphathi wenkqubo yokugaya ukutya, yenza imisebenzi eliqela ngaxeshanye. Le yinkqubo emangalisayo kakhulu. Masibone ukuba yintoni.
| Umsebenzi we-CCK hormone | Ingcaciso elula |
|---|---|
| Ukuqunjelwa kwenyongo | I-CCK iyahamba iye kunika isilumkiso kwinyongo, "Kulungile, ngoku uza kuyicinezela yonke inyongo onayo iye emathunjini amancinci." Igama elithi 'cholecystokinin' lithetha "ukuhambisa inyongo." Le nyongo yiyo esinceda sitye amafutha esiwatyayo. |
| Ukuvuselela i-pancreas | Kwangaxeshanye, i-CCK ikwathumela umyalezo kwi-pancreas, isithi, "Thumela ii-enzymes zakho ze-pancreas ngoku." Ezi enzymes ziqhekeza iiproteni kunye namafutha zibe ziisuntswana ezincinci ukuze zifunxwe ngumzimba. |
| Ukulawula ukukhupha isisu | Ngelixa le nkqubo yokugaya ukutya iqhubeka emathunjini amancinci, i-CCK ithi esiswini, "Linda umzuzu, ungathumeli ukutya okungakumbi de kube oku kutya kugayiwe." Kufana nepolisa lendlela elilawula izithuthi. Oku kuvumela inkqubo yokugaya ukutya ukuba ithathe ixesha elifanelekileyo. |
| Ukuncipha komnqweno wokutya (ukuziva uzele) | Yile nto siyivayo uninzi lwexesha. I-CCK isenza sizive sigcwele ngeendlela ezimbini. Enye kukwenza isisu sizive sigcwele emzimbeni. Enye kukuvuselela imithambo-luvo yesitho sangasese sowesifazane eludongeni lwesisu, ithumela umyalezo engqondweni othi, "Kwanele, ndizele." |
| Ukukhuthaza i-peristalsis (intshukumo yamathumbu) | Okokugqibela, i-CCK ikwanceda ekuqaliseni i-peristalsis, ukushwabana kwemisipha efana namaza okufuneka ukuhambisa ukutya okucoliweyo emathunjini. |
Iziphumo ze-CCK kwingqondo nakwinkqubo yemithambo-luvo
Ukongeza ekugayweni kokutya, uphando lufumanise ukuba i-CCK ikwachaphazela imeko yethu yengqondo. Ngokukodwa, ixhala kunye neengxaki zoloyiko.Kubonakala ngathi i-CCK inxulumene nokuxhalaba. Izifundo zibonise ukuba amanqanaba aphezulu e-CCK engqondweni anokunyusa ukuxhalaba. Uphando olongezelelweyo luyaqhubeka ngale nto.
Ziziphi iimeko zempilo ezinokunxulunyaniswa ne-CCK?
Oogqirha baye baphawula ukuba abantu abaneengxaki ezithile zempilo banamanqanaba aphantsi e-CCK. Nangona kunjalo, akukacaci ukuba oku kungenxa yesifo okanye luphawu lwesifo.
- I-Gastroparesis: Kule meko, izihlunu zesisu azisebenzi kakuhle, nto leyo ebangela ukuba ukutya kulibaziseke ekuhambeni ukusuka esiswini ukuya emathunjini amancinci. Amanqanaba aphantsi e-CCK anokuba negalelo.
- I-Biliary Dyskinesia: Oku kwenzeka xa inyongo inganciphi kakuhle kwaye ikhuphe inyongo. Oku kusenokuba kungenxa yokuba inyongo ayiphenduli kakuhle kwi-CCK.
- Ixhala kunye nokutyeba kakhulu: Abanye abantu banezakhi zofuzo ezitshintsha indlela i-CCK hormone enxibelelana ngayo nengqondo. Oku kunokukhokelela kutshintsho kwiimpawu zokulawula ukutya okanye kwiimpawu zokulawula ixhala.
Ubudlelwane phakathi kwe-CCK kunye nokukhuluphala
Le yingongoma ebalulekileyo kubantu abaninzi. Izazinzulu zenza uphando oluninzi malunga nolwalamano phakathi kwe-CCK kunye nokutyeba kakhulu.
Ezinye izifundo zibonise ukuba abantu abane-genetic variant ethile banokuba sengozini enkulu yokutyeba ngama-60%.
Kukwafunyaniswe ukuba abanye abantu abatyebe kakhulu abanayo imvakalelo ingako kwisignali "yokuzalisa" ethunyelwa yi-CCK hormone. Oku kuthetha ukuba nangona bezele, ubuchopho babo busenokungakwazi ukuyiqonda ngokuchanekileyo. Oku kunokubangela ukuba batye ngaphezu koko bakudingayo. I-CCK kunye nenye i-hormone ebizwa ngokuba yi-leptin zisebenza kunye ukulawula imiqondiso yethu yendlala kunye nokuzalisa.
Yintoni uvavanyo lweCholecystokinin?
Ngamanye amaxesha, ukuba ugqirha wakho ukrokrela ukuba inyongo yakho ayisebenzi kakuhle, unokuyalela uvavanyo olukhethekileyo ukuze abone ukuba isebenza kakuhle na. Kulapho uvavanyo lwe-CCK lwenziwa khona.
Oku kudla ngokwenziwa kunye ne -HIDA scan . I-HIDA scan siskeni esikhethekileyo esijonga ukusebenza kwezinto ezifana ne-gallbladder kunye ne-bile ducts.
Nantsi indlela yokwenza oku:
1. I-Tracer Injection: Okokuqala, ingcali iza kufaka inani elincinci kakhulu le-radioactive (tracer) emthanjeni wakho. Ungakhathazeki, oku akunabungozi emzimbeni. Le nto ihamba ngegazi kwaye iqokelelana esibindini sakho nakwinyongo.
2. Ukuskena kokuqala:Emva koko, uthotho lwemifanekiso yenyongo yakho ithathwa kusetyenziswa iskena sekhompyutha.
3. Inaliti ye-CCK: Okulandelayo yeyona nto ibalulekileyo. Ukuba ugqirha ufuna ukubona ukuba kwenzeka ntoni xa inyongo yakho iqhawuka, uza kukujova nge-hormone ye-CCK encinci ngemithambo yegazi.
4. Iskeni sesibini: Emva kokufakwa inaliti ye-CCK, okwenzekayo kuyafana naxa usitya ukutya okunamafutha. Oko kukuthi, inyongo yakho iqala ukufinyela. Ngelo xesha, bathatha olunye uthotho lwemifanekiso.
Ngokuthelekisa le mifanekiso, ugqirha unokufumanisa ukuba inyongo yakho isebenza kakuhle kangakanani na, nokuba ikhupha inyongo ngokufanelekileyo na, nokuba kukho naziphi na izithintelo.
Ngaba i-CCK isetyenziselwa unyango?
Okwangoku, i-CCK hormone ayisetyenziswa ngokuthe ngqo njengonyango lwaso nasiphi na isifo. Nangona kunjalo, ibaluleke kakhulu ekufumaneni nasekuvavanyeni amayeza amatsha.
Umzekelo:
- Amayeza okunciphisa umzimba: Ngenxa yokuba i-CCK inako ukuva ukugcwala, abaphandi bazama ukuvelisa amayeza okunciphisa umnqweno wokutya anokulinganisa loo nkqubo.
- Unyango lokuxhalaba: Inxalenye ethile ye-CCK (CCK-4) inokubangela ukuxhalaba kunye noloyiko ebantwini phantsi kweemeko ezilawulwayo. Izazinzulu zisebenzisa le ndlela ukuvavanya ukusebenza kakuhle kwamayeza amatsha ajoliswe ekunciphiseni ukuxhalaba.
Ngoko ke, i-CCK ayisiyonto nje enye emizimbeni yethu. Yikhemikhali emangalisayo echaphazela izinto ezahlukeneyo, ukusuka kwinkqubo yethu yokugaya ukutya ukuya kwimpilo yethu yengqondo, kwaye kukho okuninzi okuza kufunyanwa kwixesha elizayo.
Umyalezo Wokuya Ekhaya
- I-Cholecystokinin (CCK) yi-hormone ebalulekileyo eveliswa ngamathumbu amancinci enceda ekugayeni iproteni namafutha esiwatyayo.
- Oku kuvuselela i-gallbladder kunye ne-pancreas, kukhupha i-bile kunye nee-enzymes ezifunekayo ekugayweni kokutya.
- Le hormone ye-CCK yiyo enika ubuchopho uphawu olubalulekileyo olusixelela ukuba, "Sihluthi, sitye ngokwaneleyo." Oku kubaluleke kakhulu ekulawuleni ubunzima.
- I-CCK ikwasetyenziswa kwiimvavanyo zonyango, ezifana ne-HIDA scan, ejonga ukusebenza kwenyongo.
- Izazinzulu zisaphanda ngolwalamano oluphakathi kwe-CCK kunye neemeko ezifana nokutyeba kakhulu kunye nexhala. Ukuba unenkxalabo malunga noku, kungcono ukuthetha nogqirha wakho.
