Kodi mudadyapo chakudya chamafuta ambiri, monga biryani, kapena china chake monga curry yokometsera ndi mkaka wa kokonati, kapena chidutswa cha nsomba ndi mafuta? Mukamaliza kudya, mumaganiza kuti, "Zakwanira, mimba yanga yadzaza." Kodi mudayamba mwadzifunsapo kuti ndani kwenikweni amauza ubongo wanu kuti mimba yanu yadzaza ndipo muyenera kusiya kudya? Chimodzi mwa ntchito zofunika kwambiri za mahomoni awa omwe tikukamba lero ndi cholecystokinin. Mwachidule, ali ngati woyang'anira wofunikira kwambiri m'thupi lathu.
Mwachidule, kodi cholecystokinin ndi chiyani?
Cholecystokinin ndi mahomoni omwe amagwira ntchito ngati gawo la dongosolo lathu logaya chakudya. Homoni ndi mthenga wa mankhwala womwe umapangidwa pamalo amodzi m'thupi lathu, umayenda m'magazi, ndipo umanyamula uthenga kupita kwina. Monga positi. Cholecystokinin iyi, kapena CCK mwachidule, imatulutsidwa ndi thupi lathu titadya, pamene chakudyacho chigayidwa.
Imapangidwa makamaka ndikutulutsidwa m'matumbo athu ang'onoang'ono . Koma chodabwitsa ndichakuti, homoni iyi ya CCK imapezekanso muubongo wathu ndi m'mitsempha yathu. Koma madokotala akuyesetsabe kupeza zambiri zokhudza ntchito yake kumeneko. Nthawi zina imatchedwanso pancreozymin . Koma dzina lodziwika kwambiri lomwe limagwiritsidwa ntchito ndi cholecystokinin.
Kodi hormone iyi ya CCK imayamba bwanji kutulutsidwa m'thupi?
Tangoganizani mukudya chakudya. Chakudyacho chimapita kaye m'mimba. Pambuyo poti chagayidwa m'mimba, chakudyacho chimapita ku gawo loyamba la matumbo ang'onoang'ono. Timachitcha duodenum .
Apa ndi pomwe ntchito yeniyeni imayambira. Ngati mwadya chakudya chokhala ndi mapuloteni ambiri (monga nyama, nsomba, mazira, nyemba) ndi mafuta (monga mafuta, mkaka wa kokonati, batala), mtundu wapadera wa selo m'makoma a duodenum (wotchedwa 'maselo a I') "umazindikira" mapuloteni ndi mafuta awa. Zili ngati mlonda akuona mlendo wapadera.
Maselo amenewa akazindikira mapuloteni ndi mafuta mwanjira imeneyi, amapanga mahomoni a CCK mwachangu ndikutulutsa m'magazi mwathu. Ichi ndi 'chizindikiro' kuti CCK iyambe kugwira ntchito.
Kodi ndi zinthu ziti zazikulu zomwe zimachitika m'thupi chifukwa cha hormone ya CCK?
CCK ikangolowa m'magazi, simangokhala pamenepo. Zili ngati woyang'anira dongosolo lonse la m'mimba, akuchita ntchito zingapo nthawi imodzi. Iyi ndi njira yodabwitsa kwambiri. Tiyeni tiwone chomwe chiri.
| Ntchito ya hormone ya CCK | Kufotokozera kosavuta |
|---|---|
| Kuchepa kwa ndulu | CCK amapita kukauza ndulu kuti, "Chabwino, tsopano mufinya ndulu yonse yomwe muli nayo m'matumbo ang'onoang'ono." Mawu akuti 'cholecystokinin' amatanthauza "kusuntha ndulu." Ndulu iyi ndi yomwe imatithandiza kugaya mafuta omwe timadya. |
| Kulimbikitsa kapamba | Nthawi yomweyo, CCK imatumizanso uthenga ku kapamba, wonena kuti, "Tumizani ma enzyme anu a kapamba tsopano." Ma enzyme amenewa amaswa mapuloteni ndi mafuta kukhala tinthu tating'onoting'ono kuti thupi lizitha kuyamwa. |
| Kulamulira kutuluka kwa madzi m'mimba | Pamene njira yogayira chakudya ikuchitika m'matumbo ang'onoang'ono, CCK imauza m'mimba kuti, "Dikirani kaye, musatumize chakudya china mpaka chakudyachi chigayidwe." Zili ngati apolisi apamsewu omwe amayang'anira magalimoto. Izi zimathandiza kuti njira yogayira chakudya itenge nthawi yoyenera. |
| Kuchepa kwa chilakolako (kumva kukhuta) | Izi ndi zomwe timamva nthawi zambiri. CCK imatipangitsa kumva kukhuta m'njira ziwiri. Choyamba ndi kupangitsa mimba kumva kukhuta mwakuthupi. China ndi kulimbitsa mitsempha ya vagal m'makoma a m'mimba, kutumiza uthenga ku ubongo womwe umati, "Ndakwanira, ndakhuta." |
| Kuyambitsa peristalsis (kusuntha kwa matumbo) | Pomaliza, CCK imathandizanso kuyambitsa peristalsis, minofu yofanana ndi mafunde yomwe imafunika kuti chakudya chogayidwa chiyende m'matumbo. |
Zotsatira za CCK pa ubongo ndi dongosolo lamanjenje
Kuwonjezera pa kugaya chakudya, kafukufuku wapeza kuti CCK imakhudzanso mkhalidwe wathu wamaganizo. Makamaka, nkhawa ndi mantha.Zikuoneka kuti CCK imagwirizana ndi nkhawa. Kafukufuku wasonyeza kuti kuchuluka kwa CCK muubongo kumatha kuwonjezera nkhawa. Kafukufuku wina akupitilira pa izi.
Ndi matenda ati omwe angagwirizane ndi CCK?
Madokotala aona kuti anthu omwe ali ndi matenda enaake ali ndi CCK yochepa. Komabe, sizikudziwika bwino ngati ichi ndi chifukwa cha matendawa kapena chizindikiro cha matendawa.
- Gastroparesis: Pa vutoli, minofu ya m'mimba sigwira ntchito bwino, zomwe zimapangitsa kuti chakudya chichedwe kuchoka m'mimba kupita kumatumbo ang'onoang'ono. CCK ikhoza kukhala yotsika.
- Kusagwira bwino ntchito kwa ndulu: Izi zimachitika pamene ndulu siigwira bwino ntchito ndipo imatulutsa ndulu. Izi zitha kukhala chifukwa chakuti nduluyo siigwira bwino ntchito ku CCK.
- Nkhawa ndi kunenepa kwambiri: Anthu ena ali ndi majini osiyanasiyana omwe amasintha momwe hormone ya CCK imalumikizirana ndi ubongo. Izi zingayambitse kusintha kwa zizindikiro zowongolera chilakolako cha chakudya kapena zizindikiro zowongolera nkhawa.
Ubale pakati pa CCK ndi kunenepa kwambiri
Nkhaniyi ndi yofunika kwambiri kwa anthu ambiri. Asayansi akuchita kafukufuku wambiri pa ubale womwe ulipo pakati pa CCK ndi kunenepa kwambiri.
Kafukufuku wina wasonyeza kuti anthu omwe ali ndi majini enaake akhoza kukhala ndi chiopsezo chowonjezeka cha 60% chokhala onenepa kwambiri.
Zapezekanso kuti anthu ena onenepa kwambiri samva bwino chizindikiro cha "kukhuta" chomwe chimatumizidwa ndi hormone ya CCK. Izi zikutanthauza kuti ngakhale akhuta, ubongo wawo sungathe kuchimva bwino. Izi zingawapangitse kudya zakudya zambiri kuposa zomwe amafunikira. CCK ndi hormone ina yotchedwa leptin amagwira ntchito limodzi kuti athetse njala ndi kukhuta kwathu.
Kodi mayeso a Cholecystokinin ndi chiyani?
Nthawi zina, ngati dokotala wanu akukayikira kuti ndulu yanu sikugwira ntchito bwino, angakupatseni mayeso apadera kuti awone ngati ikugwira ntchito bwino. Apa ndiye pamene mayeso a CCK achitika.
Izi nthawi zambiri zimachitika limodzi ndi HIDA scan . HIDA scan ndi scan yapadera yomwe imayang'ana momwe zinthu monga ndulu ndi ndulu zimagwirira ntchito.
Umu ndi momwe mungachitire:
1. Jakisoni wa Tracer: Choyamba, katswiri adzalowetsa mankhwala ochepa kwambiri a radioactive (tracer) mumtsempha wanu. Musadandaule, izi sizowopsa m'thupi. Mankhwalawa amayenda m'magazi ndikusonkhanitsa m'chiwindi ndi ndulu.
2. Kujambula koyamba:Kenako, zithunzi zingapo za ndulu yanu zimatengedwa pogwiritsa ntchito kompyuta.
3. Jakisoni wa CCK: Gawo lotsatira ndilo lofunika kwambiri. Ngati dokotala akufuna kuona zomwe zimachitika ndulu yanu ikakokana, adzakulowetsani jakisoni wochepa wa CCK kudzera m'mitsempha.
4. Kujambula kwachiwiri: Mukalandira jakisoni wa CCK, zomwe zimachitika zimakhala zofanana ndi zomwe zimachitika mukadya chakudya chonenepa. Izi zikutanthauza kuti ndulu yanu imayamba kukokana. Pamenepo, amajambulanso zithunzi zina.
Poyerekeza zithunzi izi, dokotala amatha kudziwa bwino momwe ndulu yanu ikugwira ntchito, ngati imatulutsa ndulu moyenera, komanso ngati pali zotsekeka zilizonse.
Kodi CCK imagwiritsidwa ntchito pochiza matenda?
Pakadali pano, hormone ya CCK siigwiritsidwa ntchito mwachindunji ngati chithandizo cha matenda aliwonse. Komabe, yakhala yofunika kwambiri pofufuza ndi kuyesa mankhwala atsopano.
Mwachitsanzo:
- Mankhwala ochepetsa thupi: Popeza CCK imatha kumva kukhuta, ofufuza akuyesera kupanga mankhwala oletsa chilakolako omwe angatsanzire njira imeneyi.
- Chithandizo cha nkhawa: Gawo linalake la CCK (CCK-4) lingayambitse nkhawa ndi mantha mwa anthu omwe ali ndi vuto lolamuliridwa. Asayansi amagwiritsa ntchito njira imeneyi kuyesa momwe mankhwala atsopano amathandizira kuchepetsa nkhawa.
Kotero, CCK si mahomoni ena okha m'thupi lathu. Ndi mankhwala odabwitsa omwe amakhudza zinthu zosiyanasiyana, kuyambira m'mimba mwathu mpaka thanzi lathu la maganizo, ndipo pali zambiri zomwe zingapezeke mtsogolo.
Uthenga Wopita Nawo Kunyumba
- Cholecystokinin (CCK) ndi mahomoni ofunikira omwe amapangidwa ndi matumbo ang'onoang'ono omwe amathandiza kugaya mapuloteni ndi mafuta omwe timadya.
- Izi zimalimbikitsa ndulu ndi kapamba, kutulutsa bile ndi ma enzyme ofunikira kuti chimbudzi chigayike.
- Homoni ya CCK iyi ndiyo imapatsa ubongo chizindikiro chofunikira kwambiri chomwe chimatiuza kuti, "Takhuta, tadya mokwanira." Izi ndizofunikira kwambiri pochepetsa thupi.
- CCK imagwiritsidwanso ntchito poyesa matenda, monga HIDA scan, yomwe imafufuza momwe ndulu imagwirira ntchito.
- Asayansi akufufuzabe za ubale womwe ulipo pakati pa CCK ndi matenda monga kunenepa kwambiri ndi nkhawa. Ngati muli ndi nkhawa iliyonse pankhaniyi, ndi bwino kulankhula ndi dokotala wanu.
