Nepancreas ezingezizo: ngokutsha

Pathology SESWEKILE sinwenwa (DM) uthathwa sisifo eqhelekileyo kakhulu ezinxulumene waphula le nkqubo yonyango. Isifo nje iquka kuphela utshintsho carbohydrate ukutya, kodwa izaliswe iingxaki kakhulu. Kwakhona, diabetes ekuthini phakathi izinto ezibangela uphuhliso ezimbi ezingapheliyo inhliziyo. Yinto eyaziwayo ukuba ukusilela intliziyo - kakhulu isifo esiyingozi. Ngokufuthi oko kukhokelela ukusilela intliziyo, ukukhubazeka kunye nokuhla kodidi lobomi.

Diabetes sinwenwa eyenzeke ngenxa insufficiency zepancreas yonyango, okanye anciphise ukuxhathisa kwithishyu. Ngenxa yoko, insulin ayisa eziveliswe kwaye ufake igazi. Le hormone ukuze iicarbohydrate bananise, xa glucose ethile.

ingozi enkulu ukuba impilo Type 1 diabetes luphawulwa kakuhle insulin secretion. Kaninzi kwenzeka esemncinane (elivisayo), ngokukhawuleza kangaka kukhokelela umonakalo izihlunu luvo, endothelium semithambo, nephrotoxicity, kunye retinopathy.

Kwiminyaka yakutshanje, ngakumbi yaqala ukubonakala malunga nophuhliso kule qambo njengento pancreas ngumntu. Ngokutsho izazinzulu, isixhobo ezinjalo kakhulu lula ubukho izigulane kunye seswekile.

Yintoni pancreas ngumntu?

Nepancreas ibhekisa amalungu kwinkqubo yokwetyisa. injongo yawo - nokuphuhlisa enzayim eziyimfuneko ukuze nokwenziwa kokutya emathunjini. Ukongeza, le injeke abe yinxalenye yonyango. Kusenza sonwabe hormone - glucagon, somatostatin, insulin. Kwimeko ye waphula umthetho imveliso yokugqibela kuphuhliswa uhlobo 1 diabetes. An injeke yokufakelwa - isixhobo ngu ekufuneka wenziwe imveliso kwencindi egazini. Le izixhobo yindlela eyakhelwe-ngaphakathi ezisebenza umsebenzi welungu yonakele.

Indlela of action obambeleyo pancreas

Izixhobo zepancreas eyenziweyo nasenzo esi iindlela ezimbini ezinxulumeneyo. Okokuqala - oku impompo insulin. Kuye lwasungulwa ngaphambili kwaye kakhulu lula ubomi kwezigulane seswekile sinwenwa. Esi sixhobo ichibi, enoku insulin-esebenza elifutshane.

Yinto eyaziwayo ukuba izigulane unesifo "diabetes 'ukuba ukubala rhoqo isixa carbohydrate wadla kunye hormone kwesikhumba elawulwa phambi kokuba ulwamkelo ngalinye isidlo. Ukuze uphephe oku, kwenziwe pump insulin. Iqulethe insulin ngokwaneleyo, ephuma kulo igazi ngokwakho, oko kukuthi, ngaphandle iinaliti. Ukongeza, ichiza equlethwe impompo, ngokwaneleyo iintsuku ezimbalwa.

Indlela yesibini lufumaneka njengenxalenye i "ilungu" ngumntu - imitha iswekile yegazi. Mu kuya kwa nshita pump insulin, le isixhobo ingenisa ngaphantsi kwesikhumba yesigulane. Kufuneka ngenjongo iliso kwinqanaba iswekile yegazi. Zombini yasungulwa isixhobo esichazwe ekuqaleni. Umahluko phakathi kwesi sixhobo kukuba liqhagamshelaniswe nefowni 2. Ukongeza, ukuba isebenza ngaphandle. Xa usebenzisa Impompo insulin ifuna isigulane elawulwa ixabiso gqolo kulinganiswa glucose ze ubale ithamo ichiza. Le injeke yokufakelwa kuya kukunceda uthobe izigulane kulo uxanduva.

Uphawu lwe fyabo kukuba inkqubo ukugada elidityaniswe ngqo impompo insulin. Le ndlela ibizwa ngokuba "inkqubo loop evaliweyo". Ukuze esi sixhobo ukuze isebenze kakuhle, inikeza kolawulo kukho umsebenzi abanamava uyakwazi ukujonga ukusebenza idivayisi ukude. Ngenxa kule fyabo, ubomi kwezigulane uhlobo 1st seswekile, aziyi kwahluka kubantu abasempilweni. Eneneni, wayila uyakwazi ukubuyisela ngokupheleleyo organ yonakele.

Imisebenzi pancreas sokwenziwa

Eyona njongo ephambili yale kokusungulwa "umzimba" uthathwa lokulawula nethe carbohydrate. Ngokwesiqhelo, le lomsebenzi olwenziwa yi-insulin hormone. Xa Uhlobo DM 1, le nto impilo esebenzayo akukho eveliswe pancreas. Ngoko hormone kufuneka ufake egazini evela ngaphandle. Ukuzisa ubomi izigulane ubukho eqhelekileyo, oko yasungulwa ilungu ngumntu. Ezona mpawu ziphambili zale ibandakanya:

1. esweni rhoqo amaqondo eswekile yegazi. Isikali kwenziwa ngokuzimeleyo yonke imizuzu emi-5.
2. Ukwaziswa kwemithetho ye-insulin-ngokwenza elifutshane ukusuka kwimpompo in hyperglycemia. Ukufunyanwa hormone egazini kufuneka wenziwe rhoqo, ingakumbi ukusetyenziswa ngesondlo kunye ntshikilelo ngokwasemzimbeni.
3. isixhobo ulawulo liqhawuke ukusebenza ahlangeneyo ama-manzi kunye impompo insulin.

Kukho kwakhona imisebenzi umatshini imele ukubandakanya ukunciphisa umngcipheko uphuhliso yeengxaki seswekile kunye nokuphucula umgangatho wobomi kwizigulane.

Imbali zepancreas ngumntu: yophuhliso fyabo,

Ngenxa ngayo amayeza fast iyatshintsha kuba ngcono, akumangalisi ukuba kungekudala kufuneka ubone isixhobo ukuba uyakwazi ukutshintsha ngokupheleleyo ubomi izigulana insulin-oxhomekeke seswekile. Ngelishwa, nangona uphuhliso abohlukeneyo, ukusombulula le ngxaki ngokubuyisela i emzimbeni wakhe ukuba injeke nempilo phantse akunakwenzeka. Kodwa ngo-2014 Kwazeka oko malunga nophuhliso esixhobo, okwaziyo ukugcina ukutya ekudleni ngaphandle utyando yingozi. Ngelo xesha, nezesayensi okokuqala lowu malunga nokwenzeka wokudala isixhobo oza indawo pancreas. Uphando luyaqhutywa e-kumazwe amaninzi. Ngokutsho iteknoloji developers ingxelo ummangaliso, injeke enziweyo uya sele kusebenza ngo-2018. Ukuba ngaba oogqirha izibalo zichanekile, ngoko kwixesha elizayo seswekile kufuphi uzungayeki kuba sesinye sezifo ezoyikekayo, leyo ingqalelo kude.

Ulingo lwezonyango ze kokusungulwa

Iminyaka emibini, uphando enkulu ukuvumela kwixesha elizayo kufuphi ukusebenzisa isixhobo ezifana njenge pancreas ngumntu. Uya kubona isixhobo, ngokutsho abaphandi le University of Virginia ngo-2018. I omkhulu kwetyala yokuqala lwezonyango yayenzelwe ukuvavanya isixhobo, osebenza lo mgaqo "loop ezivaliweyo." Okwangoku nakuvandlakanyo ukusebenza kwefowuni.

Izimvo izazinzulu amagqirha malunga kokusungulwa

YokuFunda kunye nophuhliso ummangaliso izazinzulu zobuchwepheshe inxaxheba kumaziko eziphambili abaninzi diabetology. Ngokutsho oogqirha, ifowuni iya kuba ngomnye inkqubela enkulu amayeza.
