U-Amylase egazini, ngokutsho kweenguqu eziqhelekileyo ezithatyathwa ngobungqina bezifo ezininzi, zibambe indima ebalulekileyo ekutyeni kwe-carbohydrates kwindlela yokutya. Ngexesha elifanayo, kokunyuka kwayo kunye nokwehla kunokuthetha ngeengxaki.
Isiqhelo se-amylase egazini labantu abadala
I-Amylase iveliswa yi-pancreas, kunye ne-salivary gland. Ngomxholo we-amylase egazini kunye nomchamo ukuba oogqirha abaninzi banokumisela isifo se-pancreas okanye ezinye izitho. Ngaphantsi kwempembelelo yayo, i-carbohydrate eninzi iyanqamana. Ngokomzekelo, isitashi, i-glycogen kunye nezinye zihlahlela zibe ziincinci ezincinci njenge-glucose. Olu qhekeko lukhuthaza ukugonya okungcono kumathumbu. I-Amylase ingaba yintlobo ezimbini:
- amylase pancreatic;
- u-amylase okanye i-alpha-amylase.
Ngona nxalenye enkulu, i-amylase inokufumaneka kwi-digestive tract kwaye ayifanele ukungena kwigazi. Ukuba umsebenzi wegumbi elinama-amylase uphazamiseka, ke kuphela iprotheni idlula kwi-biological fluid. Ukuba khona kwe-amylase egazini yikhombisi ebonakalayo yezifo ezifana ne-pancreatitis okanye i-mumps.
Ngaphambi kokuba uthathe into eqhelekileyo ye-amylase egazini kufuneka ibe ngumntu omdala onempilo. Kufuneka kuqatshelwe ukuba kumntu omdala nomntwana izinga labo lingavumelana, kodwa umgangatho we-amylase egazini labasetyhini awufani namadoda. Ngako oko, kungakhathaliseki ukuba isondo, inani elipheleleyo le-amylase egazini lichongiwe, kwaye umgangatho walo ngu-28-100 U / L.
I-Alpha-amylase yi-index ye-amylase yomzimba wonke. I-Alpha-amylase yegazi inezinga eliqhelekileyo lama-25 ukuya kuma-125 iiyunithi nganye ngeyure. Kodwa ukuba ubudala bomntu buyiminyaka engaphezu kwemashumi anesixhenxe, ngoko ke izikhombisi kufuneka zibe zilandelayo-ukusuka kwiiyunivesithi ezingama-20 ukuya kwi-160 / ilitha. Ngaloo ndlela oogqirha basasaza i-amylase ye-pancreatic elingana namaqela angama-50 kwitha nganye.
Injani i-amylase ihlolwe ngeemvavanyo zegazi?
Ukuze kuqinisekiswe i-enzyme, kuyimfuneko ukuqhuba uhlalutyo lwe-biochemical yegazi le-amylase evamile. Ngenxa yoko, igazi lithathwe kwi-veiperal vein. Kule meko, amaninzi amaxesha oogqirha abacebisa izigulane zabo ukuba balungiselele ngokufanelekileyo ukuhanjiswa kwalolu hlalutyo. Ngokomzekelo, awukwazi ukuyidla ngaphambi kwenkqubo.
Ngaloo nto kubalulekile ukuqwalasela, ukuba kuyimfuneko ukunikela kwi-analysis kunye nomchamo. Isekelwe kwiziphumo zolu vavanyo olunzulu lunokucacisa imeko yepakreta. Kufuneka kukhunjulwe ukuba ukuxilongwa kuyimfuneko ukuqokelela umchamo wemihla ngemihla. Kodwa iqoqo kufuneka iqalise ngesahlulo sesibini. Ngokuqhelekileyo, isalathisi se-amylase kumchamo wansuku zonke lilingana neyunithi ye-1 ukuya kwi-17 / l.
Kufanelekile ukukhumbula ukuba umphumo wequlatho kunye nemali ye-amylase inokutshintshwa ngokubanjwa kwezidakamizwa njengoko:
- ibuprofen;
- furosemide;
- analgesics ;
- captopril;
- i-corticosteroids;
- zokukhulelwa komlomo.
Ngoko ke, ngaphambi kokuba uthathe iimvavanyo, kufuneka uyeke ukuthatha okanye ubaxelele ngamachiza abawaphule kunyango logqirha. Emva koko, ezi zinto ziyakwazi ukuphazamisa isalathisi jikelele kunye nokugqithisa.
Yintoni enokuphambuka kwimvelaphi ye-amylase?
Ukuba i-amylase yesigulana iyanda, kunokucingelwa ukuba le nto yayichukunyiswa zizifo ezinjengale:
- isifo sikashukela;
- imvumba;
- cholecystitis;
- peritonitis;
- ukuhluleka kwezintso ;
- ukhupha isisu;
- ukuguqulwa kwesilonda sesisu;
- macroamilamiya;
- ukutyhefuza (ubuninzi bexesha lotywala);
- izicubu kwi-pancreas.
Ukunciphisa i-amylase kungabonakaliswa kwezi ngxaki ezifana:
- i-hepatitis enobuhlungu okanye engapheliyo;
- i-toxicosis ngexesha lokukhulelwa;
- cystic fibrosis;
- umonakalo omkhulu wesibindi;
- pancreatectomy;
- kususwa kwe pancreas.
Ukunciphisa izinga le-amylase ngaphantsi kwesiqhelo kudla rhoqo kwiigulane ezine-cholesterol ephezulu emzimbeni.
