Cov kab mob pancreatic yog cov kob me me ntawm cov hlwb uas tsim cov tshuaj hormones uas tswj cov ntshav qabzib. Cov tshuaj hormones uas tsim nyob rau hauv pancreatic islets yog tso ncaj qha rau hauv cov hlab ntsha los ntawm tsib hom cell. Cov alpha hlwb tsim glucagon, thiab ua 15-20% ntawm tag nrho cov islet hlwb.
Islet cell transplantation ua li cas?
Txoj kev hloov pauv cov islet infusion yuav tsum ntxig ib lub raj nyias, hloov tau hu ua catheter los ntawm kev txiav me me hauv tus neeg txais lub plab sab sauv. Tus kws kho mob radiologist siv x-rays thiab ultrasound coj lub catheter mus rau hauv lub portal leeg ntawm daim siab.
Islet cells tuaj qhov twg?
Islets yog cov hlwb pom hauv pawg thoob plaws hauv lub txiav. Lawv yog tsim los ntawm ntau hom cell. Ib qho ntawm cov no yog beta hlwb, uas ua rau insulin. Insulin yog ib yam tshuaj uas pab lub cev siv cov piam thaj rau lub zog.
Yuav ua li cas cov hlwb yog cov islets?
Tib neeg islets muaj circa 30% glucagon-tsim α-cells, kwv yees li 60% insulin tsim β-hlwb, nrog rau qhov seem circa 10% ua los ntawm δ-cells. (somatostatin-producing), γ- los yog PP hlwb (pancreatic polypeptide-tsim), thiab ε-cells (ghrelin-producing) [9, 17, 18, 19, 20], nrog cov kab mob endocrine random faib …
Cov hlwb ua li cas los ntawm cov islets ntawm Langerhans?
Muaj tsib hom hlwb hauv islets ntawm Langerhans: beta cells secrete insulin; alpha hlwb secrete glucagon; PP hlwb secrete pancreatic polypeptide; delta hlwb secrete somatostatin; thiab epsilon hlwb secrete ghrelin.
