Ke islet o Langerhans o ka pancreas. Nā mea'aʻaʻa i na keena o islets o Langerhans

Kēlā me kēia islet o Langerhans hanaʻia loa, loa koʻikoʻi no ka mea a pau meaola. Kona papa kūlana - mea e kū i ka maʻiʻo o carbohydrates i loko o ke koko.

Mōʻaukala o ka Kaka

Ke islet o Langerhans i hōʻike mua i ka 1869. Discoverer o kēia mau mea nui me ka ho okumu aia i loko o ka pancreas (ʻano nui i loko o ka huelo hapa o ia), ua he'ōpiopio haumāna Rudolfa Virhova - Paul Langerhans. Ua ua ia i ka mea mua hookolokolo ma lalo o ka microscope hono o na keena, a ma kā lākou mau morphological 'ole ÿokoÿa mai nā pancreatic'aʻaʻa.

Ua Ua a laila loaʻa i ka Langerhans islets endocrine kuleana pili i ua hana. Ua loaʻa i ka KP Ulezko-Stroganov. I ka MH 1889 ua ka mua manawa i ka loulou ma waena o ka pio ana o na islets o Langerhans a me ka hooulu ana o mimikō.

He aha hiki ia i ka islet o Langerhans?

Currently, keia 'ole i ua aʻo pono lawa. Ano, i ka pono-ike i keia ho okumu iʻano. Ma ka manawa, i ka i kēia poʻe mākou iʻike:

• Alpha keena;
• Hoʻokolohua keena;
• a aaeuoa? aeee;
• pp-keena;
• epsilon keena.

Ia mea ma keia 'ano i kā lākou islet keena hana i na hana häʻawi mai ai iä ia.

Alpha-keena

Kēia? Ueo mea ma kahi o 15-20% o ka loaʻa islet. I ka papa kuhikuhiE Pahuhopu o ka Alpha-keena o ke? Iecaianoaaiiie o glucagon. Kēia hōmona i ka lipid ano a me ka mea he hoailona insulina hoa. I ka hookuu, glucagon kauoha i ke akepaa, ma ka hoʻomaopopoʻana kekahi receptors, ia regulates monakō koko? Iecaianoaaiiuo ma glycogen hālāwai hope.

Hoʻokolohua keena

Islets o Langerhans o keʻanoʻo ka loa, he pono ole. Lakou hoike no ka ma kahi o 65-80% o ka huina. Ua ua manawa hookupaa i ka papa kuhikuhiE kuleana pili i kā lākou mea e hoʻomōhala i kekahi o ka mea nui hormones - insulina. Kēia waiwai i ka hoa o ka glucagon. Ua paipai 'ia ka ho'ā hope o ka glycogen ho okumu, a ho'āhu ia i loko o ke ake a me nāʻiʻo. E like me ka hopena o kēia kaʻina mea he emi ka nui o ka monakō koko i loko o ke koko.

aaeuoa keena

Islets o Langerhans o na pancreas o keia 'ano e mai i hoʻomaka ai i ko laua manawa. Ka mea, eia wale 2-10% o ka huina. Ano, ua maopopo loa lākou ooieoeiiaeuiuo hiʻona. Ua Ua loaʻa i kēia mau keena synthesize somatostatin. I ka hana o ka biologicallyʻeleu waiwai mea e uhi i ka hanauna o ka somatotropin, somatotropin a me ka thyrotropin-opa hōmona. Ia mea, e hana ana ma luna o ka hypothalamus a me ka anterior pituitary.

PP-keena

Kēlā me kēia islet o Langerhans o ke 'ano' ole i loko o ka Anoanoaaiii o pancreatic polypeptide. A hiki i ka pau ana o kona kuleana pili i ole, ua? Anoee. Currently,ʻo ia ua aie i ka waiwai o ka uhi? Iecaianoaaiiuo o pancreatic wai. Eia hou, kona hookoia e kokua i ka hoʻonānea i laumania Muscle o ka laau make bladder. Ma nā makahiki he 'Imi? Anoee ke kaukaʻi ana o ka nui o ka? Iecaianoaaiiuo o ka waiwai, mai ke kahua mai o malignant hikoko. Ka hopena loaʻa ia ma kā lākou ulu mahuahua nui o pancreatic polypeptide. No laila, hiki ke aloha mai keia biologicallyʻeleu waiwai me ka peni mäka maikai no malignant hikoko o ka pancreas.

Epsilon keena

Mau islets o Langerhans i ka loa pinepine. O ka huina helu o ka emi o ka 1%. O ka papa kuhikuhi hana o ia keena mea e paka i ka hōmona kapaia ghrelin. Heʻeleu mea mai he nui helu o ka hana, akā, me ka loa? Anoee kona na na kanawai ma kona'ōpū.

About pathology Islets o Langerhans

Hoʻolilo i kēia mau pilikia nā hale i ma luna o ke kino ka mea nui hopena maikaʻi 'ole. I ka hanana e paka nā mea'aʻaʻa i na islets o Langerhans, i ka helu o ka hope ua progressively hoemiia. Lanakila hou ma mua o 90% o na keena emi ka? Iecaianoaaiiie o insulina a hiki i ka loi e haʻahaʻaʻilikai. Ka hopena o ka ulu ana o ia pilikia maʻi e like me mimikō. Nā mea'aʻaʻa e islet keena pinepine ana i loko o kŘpa opiopio nā mea maʻi.
