Wakambodya chikafu chine mafuta akawanda here, sebiryani, kana chimwe chinhu chakaita securry ine mukaka wekokonati, kana hove ine mafuta? Paunopedza kudya, unofunga kuti, "Zvakwana, dumbu rangu raguta." Wakambozvibvunza here kuti ndiani anoudza uropi hwako kuti dumbu rako raguta uye kuti unofanira kurega kudya? Rimwe remabasa akakosha ehomoni iyi yatiri kutaura nezvayo nhasi icholecystokinin. Zvichitaurwa zviri nyore, yakaita semaneja akakosha mukugaya kwedu.
Zvichitaurwa zviri nyore, chii chinonzi cholecystokinin?
Cholecystokinin ihormone inoshanda sechikamu chegadziriro yedu yekugaya chikafu. Hormone ikemikari inotumirwa inogadzirwa panzvimbo imwe mumuviri wedu, inofamba nemuropa, uye inotakura shoko kune imwe nzvimbo. Semupositi. Iyi cholecystokinin, kana kuti CCK muchidimbu, inoburitswa nemuviri wedu mushure mekudya, kana chikafu ichocho chagayiwa.
Inogadzirwa uye inoburitswa muura hwedu hudiki . Asi chinoshamisa ndechekuti, iyi hormone yeCCK inowanikwawo muuropi hwedu nepakati petsinga. Asi vanachiremba vachiri kuedza kutsvaga zvakawanda nezvebasa rayo ipapo. Dzimwe nguva inonziwo pancreozymin . Asi zita rinonyanya kushandiswa ndicholecystokinin.
Homoni iyi yeCCK inotanga sei kuburitswa mumuviri?
Fungidzira uchidya chikafu. Chikafu ichocho chinotanga chapinda mudumbu. Mushure mekugaya mudumbu, chikafu ichocho chinozopinda muchikamu chekutanga cheura hudiki. Tinochidana kuti duodenum .
Ndipo panotanga basa chairo. Kana wakadya chikafu chine mapuroteni akawanda (semuenzaniso nyama, hove, mazai, nyemba) nemafuta (semuenzaniso mafuta, mukaka wekokonati, bota), rudzi rwakakosha rwesero riri mumadziro e duodenum (rinonzi 'I-cells') "rinoziva" mapuroteni aya nemafuta. Zvakafanana nemurindi ari kuona muenzi akakosha.
Kana masero aya aona mapuroteni nemafuta nenzira iyi, anokurumidza kugadzira hormone inonzi CCK oiburitsa muropa redu. Ndiyo 'chiratidzo' chekuti CCK itange kushanda.
Ndezvipi zvinhu zvikuru zvinoitika mumuviri nekuda kweCCK hormone?
Kana CCK yangopinda muropa, haingogari ipapo chete. Zvakafanana nemaneja wegadziriro yese yekugaya chikafu, ichiita mabasa akati wandei panguva imwe chete. Iyi inzira inoshamisa kwazvo. Ngationei kuti chii.
| Basa reCCK hormone | Tsananguro iri nyore |
|---|---|
| Kuzvimba kwenyongo | CCK inoenda ichipa chiratidzo kunyomba, "Zvakanaka, ikozvino uchadzvanya nyomba yese yaunayo muura hudiki." Izwi rekuti 'cholecystokinin' rinoreva "kufambisa nyomba." Nyomba iyi ndiyo inotibatsira kugaya mafuta atinodya. |
| Kukurudzira pancreas | Panguva imwe chete, CCK inotumirawo shoko kupancreas, ichiti, "Tumira maenzymes ako epancreas izvozvi." Maenzyme aya anopwanya mapuroteni nemafuta kuita zvidimbu zvidiki kuitira kuti akwanise kutorwa nemuviri. |
| Kudzora kubuda kwemvura mudumbu | Panguva iyi kugaya chikafu kuri kuitika muura hudiki, CCK inoudza mudumbu kuti, "Mira zvishoma, usatumire chimwe chikafu kusvika chikafu ichi chagayiwa." Zvakafanana nemapurisa emumugwagwa ari kudzora traffic. Izvi zvinoita kuti kugaya chikafu kutore nguva chaiyo. |
| Kudzikira kwechido (kunzwa kuguta) | Izvi ndizvo zvatinonzwa nguva zhinji. CCK inoita kuti tinzwe takaguta nenzira mbiri. Imwe ndeyekuita kuti dumbu rinzwe rakaguta. Imwe ndeyekukurudzira tsinga dzemukati medumbu, zvichitumira chiratidzo kuuropi chinoti, "Zvakwana, ndaguta." |
| Kukurudzira kufamba kwematumbo (peristalsis) | Pakupedzisira, CCK inobatsirawo kutanga peristalsis, kusimba kwetsandanyama kwakaita semafungu kunodiwa kuti chikafu chakagayiwa chiendeswe mudumbu. |
Mhedzisiro yeCCK pauropi netsinga
Pamusoro pekugaya chikafu, tsvakurudzo yakawana kuti CCK inokanganisawo pfungwa dzedu. Kunyanya, kuzvidya mwoyo uye kutya zvakanyanya.Zvinoita sekuti CCK ine chekuita nekuzvidya mwoyo. Zvidzidzo zvakaratidza kuti kuwanda kweCCK muuropi kunogona kuwedzera kuzvidya mwoyo. Kutsvagurudza kuri kuenderera mberi panyaya iyi.
Ndezvipi zvirwere zvinogona kukonzerwa neCCK?
Vanachiremba vakaona kuti vanhu vane mamwe matambudziko ehutano vane huwandu hwakaderera hweCCK. Zvisinei, hazvisati zvanyatsojeka kana ichi chiri chikonzero chechirwere ichi kana kuti chiratidzo chechirwere ichi.
- Gastroparesis: Mumamiriro ezvinhu aya, tsandanyama dzemudumbu hadzishande zvakanaka, zvichiita kuti chikafu chinonoke kufamba kubva mudumbu kuenda muura hudiki. Kunogona kunge kwakaderera CCK.
- Kusagadzikana kweBiliary: Apa ndipo apo nduru isingagadzikane zvakanaka uye inoburitsa nduru. Izvi zvinogona kunge zvichikonzerwa nekuti nduru haipindure zvakanaka kuCCK.
- Kuzvidya mwoyo uye kufuta: Vamwe vanhu vane majini akasiyana-siyana anochinja nzira iyo hormone yeCCK inosangana nayo neuropi. Izvi zvinogona kutungamira kuchinjwa kwezviratidzo zvekudzora kudya kana zviratidzo zvekudzora kuzvidya mwoyo.
Hukama huripo pakati peCCK nekufutisa
Iyi inyaya inokosha kuvanhu vazhinji. Masayendisiti ari kuita tsvakurudzo yakawanda pamusoro pehukama huripo pakati peCCK nekufutisa.
Dzimwe ongororo dzakaratidza kuti vanhu vane majini akasiyana vanogona kunge vaine mukana wekuwedzera wekufuta ne60%.
Zvakaonekwawo kuti vamwe vanhu vakafuta havanzwisisi zvakanyanya chiratidzo chekuti "kuzara" chinotumirwa neCCK hormone. Izvi zvinoreva kuti kunyangwe vakaguta, pfungwa dzavo dzingasakwanisa kuzviona nemazvo. Izvi zvinogona kuita kuti vadye zvakawandisa kupfuura zvavanoda. CCK neimwe hormone inonzi leptin inoshanda pamwe chete kudzora zviratidzo zvedu zvenzara nekuguta.
Chii chinonzi Cholecystokinin Test?
Dzimwe nguva, kana chiremba wako achifungidzira kuti gallbladder yako haisi kushanda zvakanaka, anogona kuraira bvunzo yakakosha kuti aone kana iri kushanda zvakanaka. Apa ndipo panoitwa bvunzo yeCCK.
Izvi zvinowanzoitwa pamwe chete neHIDA scan . HIDA scan inyanzvi yekuongorora inotarisa mashandiro ezvinhu zvakaita sedundira redu remudumbu neremudumbu.
Heino maitiro ekuzviita:
1. Kubaya Majekiseni eTracer: Kutanga, nyanzvi yezvemagetsi ichabaya huwandu hushoma hwechinhu chine radioactive (tracer) mutsinga yako. Usazvidya moyo, izvi hazvikuvadzi muviri. Chinhu ichi chinofamba nemuropa uye chinoungana muchiropa chako negallbladder.
2. Kutanga kuskena:Zvadaro, mifananidzo yakawanda yenduru yako inotorwa uchishandisa computer scanner.
3. Jekiseni reCCK: Chinotevera ndicho chinonyanya kukosha. Kana chiremba achida kuona zvinoitika kana gallbladder yako yadonha, achakubaya jekiseni diki reCCK kuburikidza netsinga.
4. Kuongororwa kwechipiri: Mushure mekubaiwa jekiseni reCCK, zvinoitika zvakafanana nekudya chikafu chine mafuta. Kureva kuti, gallbladder yako inotanga kugayiwa. Panguva iyoyo, vanotora mimwe mifananidzo.
Nekuenzanisa mifananidzo iyi, chiremba anogona kuona kuti nduru yako iri kushanda zvakanaka sei, kana iri kuburitsa nduru nemazvo, uye kana paine zvimwe zvinovhara.
CCK inoshandiswa here pakurapa?
Parizvino, hormone yeCCK haishandiswi zvakananga sekurapa chero chirwere chipi zvacho. Zvisinei, yave kukosha zvikuru pakutsvaga nekuyedza mishonga mitsva.
Semuyenzaniso:
- Mishonga yekuderedza huremu: Nekuti CCK ine kugona kunzwa kuguta, vaongorori vari kuedza kugadzira mishonga inoderedza chishuwo chekudya inogona kutevedzera maitiro iwayo.
- Kurapa Kunetseka: Chikamu chakati cheCCK (CCK-4) chinogona kukonzera kuzvidya mwoyo nekutya muvanhu kana mamiriro ezvinhu akadzorwa. Masayendisiti anoshandisa nzira iyi kuyedza kushanda kwemishonga mitsva yakagadzirirwa kuderedza kuzvidya mwoyo.
Saka, CCK haisi imwe hormone iri mumiviri yedu. Imutumwa wemakemikari anoshamisa anokanganisa zvinhu zvakasiyana-siyana, kubva mukugaya kwedu kusvika kuhutano hwedu hwepfungwa, uye kune zvakawanda zvichawanikwa mune ramangwana.
Mharidzo Yekuenda Nayo Kumba
- Cholecystokinin (CCK) ihormone inokosha inogadzirwa neura hudiki iyo inobatsira kugaya mapuroteni nemafuta atinodya.
- Izvi zvinosimudzira gallbladder nepancreas, zvichiburitsa bile nema enzymes anodiwa pakugaya chikafu.
- Homoni iyi yeCCK ndiyo inopa uropi chiratidzo chakakosha chinotiudza kuti, "Taguta, tadya zvakakwana." Izvi zvakakosha zvikuru pakuderedza uremu.
- CCK inoshandiswawo muongororo dzekurapa, dzakadai seHIDA scan, iyo inoongorora mashandiro egallbladder.
- Masayendisiti achiri kutsvaga hukama huripo pakati peCCK nemamiriro ezvinhu akadai sekufutisa nekuzvidya mwoyo. Kana uine zvinokunetsa nezvazvo, zvakanaka kutaura nachiremba wako.
