The islet wa Langerhans a kapamba. Chitetezo ku maselo a Zilumba za Langerhans

Aliyense islet wa Langerhans amachita zofunika kwambiri kwa chamoyo wonse. udindo waukulu - ndi kulamulira zili chakudya m'magazi.

History of anapeza

The islet wa Langerhans anafotokozedwa koyamba mu 1869. Anatulukira formations ofunika ili mu kapamba (makamaka mchira gawo la izo), anali mnyamatayu Rudolfa Virhova - Paul Langerhans. Iye ndiye anali woyamba kufufuza maikulosikopu m'bulu wa maselo, lomwe ndi dongosolo lawo morphological isiyana ndi zina pancreatic minofu.

Kuti pambuyo pake anapeza kuti Langerhans Zilumba endocrine ntchito imagwiridwa. kupezeka yotentha ndi kp Ulezko-Stroganov. Mu 1889 kanali koyamba kugwirizana pakati pa kugonja kwa Zilumba za Langerhans ndi chitukuko cha matenda a shuga.

Kodi ukhoza kukhala islet wa Langerhans?

Panopa, kapangidwe wakhala anaphunzira bwino. Tsopano odziwika kuti mapangidwe uyu ali zosiyanasiyana. Panthawi ino, tikudziwa anthu otsatirawa:

• maselo Alpha;
• maselo beta;
• maselo ankadziwana;
• mas-maselo;
• epsilon maselo.

Ndi kupyolera zosiyanasiyana izi maselo awo islet kuchita ntchito zonse wawapatsa.

Alpha-maselo

mitundu ndi za 15-20% ya islet zilipo. Cholinga chachikulu cha alpha-maselo yopanga glucagon. timadzi uyu ali ndi zamadzimadzi chilengedwe ndipo ndi achilendo insulin antagonist. Pamene anamasulidwa glucagon anawalozera kwa chiwindi, kumene polumikizana ndi maselo zimenezi, nthawi yopanga shuga ndi glycogen kusokonezeka.

maselo beta

Zilumba za Langerhans zosiyanasiyana ndi ambiri. Iwo mlandu za 65-80% ya chonse pamodzi. Tsopano anakhazikitsa kuti ntchito yaikulu ndiyo kukhala mmodzi wa mahomoni chofunika kwambiri - insulin. mankhwala ndi antagonist wa glucagon lapansi. Imalimbikitsa kutsegula kwa glycogen mapangidwe ndi kasungidwe mu chiwindi ndi akatumba. Chifukwa cha ndondomekoyi ndi kuchepa kuchuluka kwa shuga m'magazi.

maselo Delta

Zilumba za Langerhans a kapamba wa mtundu uwu sanalembedwepo nthawi. Iwo% 2-10 yekha wa chonse pamodzi. Tsopano zizindikiro zawo zinchito zimadziwika bwino. Anapeza kuti maselo amenewa lithe somatostatin. Ntchito ya thunthu biologically yogwira ndi kupondereza m'badwo wa somatotropin, somatotropin ndi thyrotropin-kumasuka timadzi. Ndiko kuti, amachita mwachindunji pa ubongo imene imalamulira kutentha ndi zapambuyo pituitary.

PP-maselo

Aliyense islet wa Langerhans a mtundu nawo elaboration wa polypeptide pancreatic. Mpaka mapeto a ntchito yake sichinayambe kuphunzira. Panopa, iye akutchedwa katundu wa kupondereza ulimi wa madzi pancreatic. Komanso, zotsatira zake amathandiza kumasuka minofu yosalala ya chikhodzodzo ndulu. M'zaka zaposachedwapa ndithu mwakhama kuphunzira kudalira pa mlingo wa ulimi wa thunthu kwa mapangidwe zotupa zilonda. The chifukwa azindikira kuti chitukuko chinawonjezeka mlingo wa polypeptide pancreatic. Kotero izi mankhwala biologically yogwira angathe kuonedwa ngati chikhomo chabwino zotupa zilonda za kapamba.

maselo Epsilon

Izi Zilumba za Langerhans ndi pafupipafupi kwambiri. Wa n'kulemba okwana zosakwana 1%. Ntchito yaikulu ya maselo amenewa ndi kutulutsa timadzi otchedwa ghrelin. nkhaniyi yogwira ali ambiri ntchito, koma kwambiri kuphunzira chilangizo zotsatira kudya.

About kudwala Zilumba za Langerhans

Akunde nyumba zino ali pa thupi kwambiri mavuto. Kukachitika kuti apange chitetezo ku Zilumba za Langerhans, chiwerengero cha otsiriza anachepetsa pang'onopang'ono. Akunde oposa 90% ya maselo amachepetsa yopanga insulin pa mlingo otsutsa otsika. Chifukwa ndi chitukuko cha matenda oopsa monga a shuga. Chitetezo kwa islet maselo amayambira odwala wachinyamata.

Akuluakulu kuwononga anthu maselo angathe gormonprodutsiiruyuschih chifukwa kutupa kapamba - kapamba.

Kodi kupulumutsa maselo islet?

Adzakula kusamalira kapamba lonse wonse. Choyamba m'pofunika kuti asiye khalidwe lotayirira la mowa. chakuti ali pa kapamba wa onse chakudya zimakhudza kwambiri negative. Mu nkhani ya mowa yaitali mowa anthu amapezeka ndi m'kati kapamba, kenako kungachititse kuti ndithu maselo mantha islet.

Kuwonjezera mowa mokwanira musamala bwino pa kapamba ali wambirimbiri wolemera nyama mafuta chakudya. Pankhaniyi, zinthu adzakhala amakula ngati pasadafike phwando mtima kwa nthawi yaitali osadya kanthu.

Mu chochitika mu minofu pancreatic kale aakulu yotupa ndondomeko, pamafunika kukaonana ndi katswiri - dokotala kapena gastroenterologist. Information ukatswiri madokotala kusankha njira zomveka mankhwala, amene akhoza kwambiri m'mbuyo chitukuko cha kusintha pathological. Hereinafter udzachitike ultrasound kapamba chaka chilichonse chimene anachita osakaniza ndi ziwalo zina za zinthu zonse m'mimba. Komanso, m'pofunika kuti atenge kusanthula amuzolengedwa magazi zili ake amylase.

Kudziwa isanayambike kapamba aakulu, kuwonjezera pa zasayansi zoimbidwa maphunziro, kungathandize chipatala. The chizindikiro chachikulu cha matenda Maonekedwe a ululu lamanzere nusu chapamwamba. Ndiponso, izi zoster ululu khalidwe ndi kumachitika kawirikawiri atakhala wambiri wolemera nyama mafuta chakudya. Komanso wodwalayo pambuyo chakudya angakhale nkhawa kumverera zonse kulemera m'mimba. Zizindikiro zonsezi kusiya kudya mokwanira kapena kuchepetsa ukulu wake mu odwala kulandira mankhwala okhala pancreatin. Pakati pawo, mankhwala otchuka ali "Creon", "mezim" ndi "Pancreatin". Ngati muli ndi kutupa mu kapamba minofu bwino ndipo safuna konse ku kumwa mowa. mfundo ndi yakuti ngakhale pang'ono zingawonjezere ndondomeko matenda m'thupi, potero kwambiri kuvulaza thupi.
