Chikhansa ndichinthu chofunikira kwambiri pakukonza chakudya chamunthu. Ndiyewofalitsa wamkulu wa ma enzymes, popanda zomwezi ndizosatheka kugaya bwino mapuloteni, mafuta ndi chakudya. Koma kutulutsidwa kwa madzi a pancreatic sikungokhala ndi zochita zake. Zida zapadera za gland ndi zisumbu za Langerhans, zomwe zimagwira ntchito ya endocrine, kubisa insulin, glucagon, somatostatin, pypreatic polypeptide, gastrin ndi ghrelin. Ma hormone a pancreatic amakhudzidwa ndi mitundu yonse ya kagayidwe, kuphwanya kupanga kwawo kumabweretsa kukula kwa matenda oopsa.
Pancreas endocrine
Maselo a pancreatic omwe amapanga zinthu zomwe zimagwira ntchito mu ma cell amatchedwa insulocytes. Amapezeka pazitsulo ndi masango - zilumba za Langerhans. Kuchuluka kwa zilumbazi ndi 2% yokha ya kulemera kwa chiwalocho. Mwapangidwe, pali mitundu ingapo ya ma insulocytes: alpha, beta, delta, PP ndi epsilon. Mtundu uliwonse wamaselo umatha kupanga ndi kubisa mtundu wina wa mahomoni.
Kodi ma kapamba amapanga mahomoni ati?
Mndandanda wamahomoni apancreatic ndiwowonjezereka. Zina zimafotokozedwa mwatsatanetsatane, pomwe zomwe ena sanaphunzirepo zokwanira. Yoyamba ndi insulini, yomwe imawerengedwa ngati mahomoni ophunziridwa kwambiri. Oyimira zinthu zogwiritsa ntchito kwachilengedwe, omwe amaphunzira mosakwanira, amaphatikiza polypeptide ya pancreatic.
Maselo apadera (maselo a beta) a zisumbu za Langerhans za kapamba amapanga mahomoni a peptide otchedwa insulin. Kuwonekera kwa zochita za insulin ndikotakata, koma cholinga chake chachikulu ndikuchepetsa kuchuluka kwa shuga m'magazi am'magazi. Zokhudza kagayidwe kazakudya zimazindikira chifukwa cha kuthekera kwa insulin:

Ngati simutembenukira kwa katswiri pakanthawi ndikuyamba kulandira chithandizo, izi zimatha kuyambitsa kupanikizika kwa chifuwa, chifuwa, magazi, mitsempha yodwala, kuwonongeka kwa ziwalo zina ndi kuledzera kwambiri kwa thupi
Kodi pancreatic steatosis ndi yoopsa bwanji?
Akatswiri sagwirizana chimodzi pamaganizidwe awo, steatosis ndi matenda amoyo wonse, kotero kuyembekeza chitsitsimutso chokwanira cha gland ndikosatheka. Chifukwa chake, chithandizo chamankhwala chimalimbikitsa kuti achedwetse
Zimayambitsa mapangidwe a polyps mu kapamba ndi njira zochizira
Ndi kuwunikira kwakanthawi kachipatala komanso kulandira chithandizo kwakanthawi koyamba m'magawo awo, izi zimachiritsidwa kwathunthu, popanda zovuta komanso zovuta zina.
Mapangidwe ndi ntchito
Chikhansa ndichinthu chogaya, motero ndikofunikira kudziwa kapangidwe kake ndi ntchito zake. Mutu ndiye malo okula kwambiri, ozunguliridwa ndi minyewa ya duodenum 12. Thupi la kapamba limakhala ndi nkhope zakunja, zamphongo, nkhope zakumunsi. Mchira wokweza umayendetsedwa kutsogolo chakumanzere. Kutalika kwa limba kumayambira 16 mpaka 23 cm.
Minyewa ya kapamba imachita zinthu ziwiri zothandizira thupi:
- Ntchito yakunja (exocrine) - ndi yomwe imayambitsa kutulutsa madzi am'mimba. Derali limapangidwa ndi mgwirizano wamaselo mu zilumba za Langerhans, pomwe zinthu zazikulu za mahomoni zimamasulidwa.
- Cholinga chamkati (endocrine) - chimadziwika ndi ntchito ya mahomoni ofunikira m'thupi, amatenga nawo mbali popanga mafuta, chakudya, mapuloteni.
Chofunikira ndichakuti kapamba amatulutsa mahomoni. Ma hormone a pancreatic ndi omwe amachititsa kuti pakhale kupangika, kupatsa mphamvu, komanso kuyendetsa shuga kudzera ziwalo.
Chizindikiro cha mahomoni apancreatic
Ma hormone a pancreatic amawonedwa ngati gawo la thupi. Chifukwa chake, ndikofunikira kudziwa zomwe ma kancisi amapanga, kapangidwe kake, mphamvu ya minofu ndi ziwalo.
Horoni ya pancreatic, insulin, imatenga nawo gawo lonse lathupi. Ntchito yake yofunika ndicholinga chotsitsa shuga m'magazi, zomwe zimachitika ndikuyambitsa zochitika zamagulu azakumwa za shuga, mayamwidwe ake ndi minofu ndi minyewa. Kuphatikiza apo, mahomoni a pancreatic amawongolera kagayidwe kazakudya zamafuta ndi mafuta.
Magwiridwe a insulin aperekedwa:
- kapangidwe ka lipocaine. Amayang'anira kutsekeka ndi kutembenuka kwa hepatocytes,
- kutsegula kwa kusintha kwa chakudya mu mafuta, pambuyo pake.
- kusintha monosaccharides m'magazi,
- Kusintha glucose kukhala mafuta ndikuisunga m'thupi,
- kuchuluka kwa ma tetracyclines.
Ngati ndizosatheka kuti kapamba athe kuthana ndi kuphatikiza kwakukulu, vuto lina limachitika pa mahomoni. Ndi kuperewera kwakukulu kwa kuchuluka kwa insulin, njira yosasintha imachitika. Kutsika kwa katulutsidwe ka insulin kumayambitsa matenda ashuga. Ndi nthendayi, ndolo ya shuga imakwera pamwamba pa 10 mmol / L, yomwe imayambitsa kutuluka kwa mkodzo, ndikulowetsa mamolekyulu am'madzi, omwe amayamba kutuluka madzi ambiri, madzi am'mimba.
Pankhani yopanga insulin kwambiri, shuga amawonjezeka, shuga amachepetsa, adrenaline imadzuka.
Limagwirira ntchito ikuchitika zotsatirazi:
- Insulini imathandizira kuti shuga isamasanduke.
- Kuchulukitsa kuchuluka kwa shuga kumachitika ndi ma cell.
- Imayambitsa ntchito ya ma enzymes omwe amathandizira glycolysis, omwe ndi makutidwe ndi okosijeni a mamolekyulu a shuga ndikupanga 2 mamolekyulu a pyruvic acid kuchokera pamenepo.
- Imathandizira kukulitsa kwamitsempha yama cell.
- Imawonjezera zinthu zama glucose monga glycogen, yomwe imayikidwa mu minofu ya minofu ndi chiwindi ndikutenga gawo la glucose-6-phosphate.
- Kuchita kwa insulin kumalepheretsa kuwonongeka kwa glucagon, komwe kumakhala ndi vuto la insulin.
Gawo lalikulu la kapangidwe ka glucogon ndi maselo a zida za alpha chilumba cha kapamba. Poterepa, mapangidwe a glucagon ochulukirapo amawonekera m'malo ena am'mimba ndi matumbo.
Glucagon ndi mdani wa insulin pochita.
Glucagon amalimbikitsa kutsegula kwa glycogenolysis, kusungidwa kwa glycogen synthase mu chiwindi, chifukwa chomwe glycogen-1-phosphate glycogen imamasulidwa, yomwe imasandulika 6 phosphate. Kenako, mothandizidwa ndi glucose-6-fostofatase, shuga waulere amapangidwa, yemwe amatha kutuluka mu cell kupita m'magazi.
Chifukwa chake, mahomoni amathandizira kukulitsa kuchuluka kwa glucose chifukwa cholimbikitsa chiwindi ndi chiwindi, chimateteza chiwindi kuti chichepetse shuga, komanso zimathandizira pakupanga shuga wofunikira pantchito yachilengedwe. Glucagon imathandizira kuwonjezera magazi mu impso, kutsitsa cholesterol, imathandizira kupanga kuchuluka kwa insulin. Chifukwa cha mahomoni, lipids ya minofu ya adipose imaswanso.
Polypeptide
Kumangiriza kwake kumachitika pang'onopang'ono. Momwe ma polypeptide amathandizira pa metabolic phenomena sanadziwikebe. Pamene polypeptide imayendetsedwa ndi magwiridwe antchito a thupi, imayamba kubwezeretsanso zochita za kapamba, kukankhira zipatso zamadzi m'mimba.
Pakuphwanya kapangidwe ka thupi pazifukwa zosiyanasiyana, chinsinsi chomwecho mu nthawi yoyenera sichingachitike.
Gastrin imathandizira kupanga haidrojeni chloride, imawonjezera zokolola zam'madzi za m'mimba ndi maselo akuluakulu a chiwalo, imapanga ndikuwonjezera ntchito ya mabicorbates ndi ntchofu mu mucosa wa m'mimba, chifukwa chotsatira chomwe membrane wa membala amathandizira chifukwa cha zovuta za pepsin ndi hydrochloric acid.
Mahomoniwa amachedwetsa ntchito yotulutsa m'mimba. Izi zimapereka kutalika kwa mphamvu ya pepsin ndi asidi pa chyme chofunikira pa chakudya cham'mimba. Ndipo amatha kuwongolera machitidwe a kusinthana kwa chakudya chamafuta, chifukwa chake, amathandizira kupanga ma peptide ndi mahomoni ena.
Zinthu zina zogwira ntchito
Ma mahomoni ena apachifwamba apezeka.
- Lipocaine - amatha kuchititsa kuti pakhale mafuta komanso makulidwe amtundu wa aliphatic monobasic carboxylic acid, amateteza chiwindi ku steatosis.
- Centropnein - imakhudza mosangalatsa malo apakati a ubongo, amathandizira kupumula kwa minofu ya bronchial.
- Vagotonin - imawonjezera ntchito ya nyini,
Kodi mankhwalawa ndi mahomoni a pancreatic
Zofunikira zimayesedwa ngati mankhwala a insulin, omwe amapangidwa ndi makampani osiyanasiyana azamankhwala. Mankhwala a pancreatic amasiyanitsidwa ndi zizindikiro.
Mwa chiyambi, mankhwalawa ndi:
- mankhwala achilengedwe - Actrapid, Monotard MC, tepi ya Insulin GPP,
- kapangidwe - Homofan, Humulin.
Mwa kuthamanga, nthawi yayitali:
- Kuthamanga ndi kwakanthawi, mankhwala amawonetsa mphamvu zawo pakatha ola limodzi pambuyo pa kuperekedwa, mankhwalawa ali pafupifupi maola 8 - Insuman mwachangu, Actrapid,
- pafupifupi nthawi ya kukopa, akuwonekera patatha maola 2 atagwiritsidwa ntchito, mphamvu ya mankhwalawa mpaka tsiku - Tepi la Humulin, Monotard MC
- pafupifupi nthawi yayitali ya insulin ndi kufupikitsika, kuyambika kwa theka la ola - Actrafan HM.
Ma mahormoni ndi ofunikira pakuwongolera kayendetsedwe kazomwe thupi limachita, chifukwa chake ndikofunikira kudziwa kapangidwe ka chiwalo, chomwe ma pancreatic mahomoni amakhala ndi ntchito zawo.
Ma pathologies okhudzana ndi njira yogaya chakudya amawoneka, dokotala amakulemberani mankhwala othandizira. Mayankho a dokotala pancreatitis athandizira kumvetsetsa zomwe zimayambitsa matendawa komanso momwe angachiritsire.
