I-insulin yi-hormone apho i-pancreas iphendula. Umsebenzi walo oyintloko kukuthutha i-glucose, amafutha, amino acids kunye ne-potassium kwiiseli. Ukongeza, i-substance ilawula izinga leswekile egazini kwaye lijongene nokulawula ibhalhyidrate ibhalansi. Konke oku kwenzekayo xa i-insulin egazini labesetyhini iqulethwe kwisixa esiqhelekileyo. Kodwa ngenxa yezizathu ezahlukahlukeneyo, inani le-hormone lingahluka. Kwaye oko kuyachaphazela imeko yezempilo nempilo.
Yintoni eqhelekileyo ye-insulin egazini labasetyhini ukutya?
Ukufumana idatha ethembekileyo, kuyimfuneko ukulinganisa izinga le-insulin kwisisu esingenalutho. Ukuba uhlalutya emva kokutya, idatha iya kuphazamiseka. Oku kwenzeka kuba emva kokutya i-pancreas iqala ukusebenza kwaye iyasebenza kakhulu ekuveliseni ihomoni. Ngenxa yoko - ngenxa yoko, umxholo wezinto ezikhoyo egazini ziya kuba phezulu.
Isiqhelo se-hormone insulin kubafazi besuka ku-3 ukuya ku-20 μU / ml. Ukunyuka kancinci kwimiba yokukhulelwa kunokwenzeka, njengommiselo, baqala ukusuka kwi-6 ukuya kwi-27 microU / ml. Isixa sempahla kubantu asebekhulile sitshintshela kwinxalenye enkulu. Emva kweminyaka engama-60, kuyinto eqhelekileyo ukuba amanqanaba egazi angama-6 ukuya ku-35 μU / ml ye-hormone ayafunyanwa.
I-insulini egazini labesetyhini ngokubaluleka okuqhelekileyo liqinisekisa ukusetyenziswa kweenkqubo ezibalulekileyo:
- Ixabiso lakha imisipha. Ikhuthaza ukusetyenziswa kweerbosomes ezidibanisa iprotheni, leyo leyo ibandakanyeka ekwakheni izicubu zomzimba.
- Ngombulelo kwi-insulin, iiseli ze-muscle zingasebenza ngokuchanekileyo.
- I-substance inqanda ukuphahlaka kwemisipha yomzimba.
- Ngomlinganiselo oqhelekileyo, i-insulin kumabhinqa emzimbeni ukwandisa umsebenzi wee-enzyme ezijongene nokuveliswa kwe-glycogen. Okukugqibela, yindlela ephezulu yokugcina i-glucose.
Ukuba abafazi banezinga le-insulin eliphezulu okanye eliphantsi kuneqhelekileyo
Ukwanda okwenene kwindleko yehommoni kunokubonisa:
- ukuphazamiseka kweengxaki ze- pituitary ;
- uhlobo lwesibini lwesifo sikashukela;
- izifo ze-pancreas;
- I-Cushing's syndrome;
- ukunyanya;
- i-myotonia ekhohlakeleyo;
- i-acromegaly;
- ovary polycystic.
Ukungakwazi ukusebenza kwe-insulin egazini kunemiba enje:
- isifo sikashukela soluhlobo lokuqala;
- isifo sikashukela ;
- sulelo;
- ukugqithisa ukhathazeka komzimba;
- ukunyanzelisa umzimba;
- yokuphila.
