Urea egazini yinto yokuveliswa kweeprotheni. Urea iveliswa sisibindi kwinkqubo yeprotheni yangaphambili kwaye ikhutshwe ngeentso kunye nomchamo. Ukumisela izinga le-urea yabantu, uvavanyo lwegazi lwe-biochemical. Isiqhelo se-urea egazini sinxulumene nobudala kunye nesondo: kwabesetyhini kuncinci. Ulwazi oluthe ngqo malunga nomgangatho we-urea egazini labesetyhini, unokufunda kwinqaku.
Iqondo le-urea egazini - eliqhelekileyo kwabasetyhini
Amazinga e-Urea kwabasetyhini abangaphantsi kweminyaka engama-60 avela kwi-2.2 ukuya kuma-6.7 mmol / l, ngelixa lendoda, isiqhelo siphakathi kwe-3.7 no-7.4 mmol / l.
Xa uneminyaka engama-60, isiqhelo samadoda nabasetyhini sifana ngokufanayo kwaye sikwi-2.9-7.5 mmol / l.
Ezi zinto zilandelayo zichaphazela umxholo we-urea:
- umsebenzi wesibindi;
- imeko esebenzayo yeentso;
- kwinqanaba lama-amino acids abandakanyekayo kwiprotheni yamathambo.
Umxholo we-urea kwigazi kwabasetyhini abangaphantsi kwesiqhelo
Ukuba ngenxa yoluhlalutyo lwamachiza umfazi unomxube ophantsi we-urea egazini lakhe xa uthelekiswa nesiqhelo, izizathu zolu tshintsho lunokuba:
- ukutya, kunye nokukhutshwa ekudleni kweemveliso zezilwanyana (inyama, amaqanda, ubisi) kunye nentlanzi okanye ixesha lokulala yindlala;
- isifo sesibindi (i-hepatitis, cirrhosis, hepatodystrophy, coma hepatic);
- i-acromogyd - i-hormonal pathology, ibonakaliswe ngendlela yokwanda okungavaliyo kwimizimba yomzimba;
- iingxaki kwi-thyroid gland;
- utyhefu ngeemveliso eziqukethe i-arsenic kunye ne-phosphorus;
- i-malabsorption - ukunciphisa ukunciphisa ama-amino acids kumathumbu.
Ngokuqhelekileyo kuncipha kwinqanaba le-urea egazini labasetyhini abakhulelweyo. Olu tshintsho lubangelwa kukuba iprotheni yomama isetyenziselwa ukwakha umzimba womntwana ongakazalwa.
Uxinzelelo oluphezulu lwe-urea egazini
Amanqanaba angaphezulu kwamarerea ahlala ebonisa ukugula okukhulu. Ngokuqhelekileyo, izinga eliphezulu lemveliso liyabonwa kwizifo ezinjenge:
- Ukuhluleka kwezintso kunye nezinye izifo zeentso (i-pyelonephritis, i-glomerulonephritis, isifo sesifo sofuba, njl);
- ukuphulwa kokuphuma komchamo ngenxa yolurolithiasis, isisu esiqheqweni, njl.;
- i-myocardial infarction kunye nokuhluleka kwentliziyo;
- isithintelo esiswini;
- ukuphuma kwamanzi;
- hyperthyroidism;
- leukemia;
- isifo sikashukela (ngenxa yokuphazamiseka kwe-urrea excretion);
- leukemia ;
- kutshisa amanxeba;
- ukutshitshiswa kobuso;
- utyhefu ngezinto ze-mercury-containing containing, oxalic acid and phenol;
- ukukhulelwa kwamanzi omzimba ngenxa yoluhudo okanye ukuhlanza.
Kwakhona, uxinzelelo oluphezulu lwe-urea egazini lunokuba ngumphumo wesimo esinamandla kakhulu (kubandakanya ukuqeqeshwa okunzulu) okanye i-predominance of foods of protein ekudleni. Ngamanye amaxesha izinga le-urea linyuka ngenxa yokuphendula komzimba ngamnye ukuba kuthathe unyango, kuquka:
- anabolics;
- i-corticosteroids;
- i antibiotics;
- sulfonamides.
Ukwanda okwenyukayo kwi-urea kumachiza kuthiwa uremia (hyperaemia). Le meko ibangelwa kukuba ukuqokelela kwiiseli zomkhuhlane kubangela ukwanda kwawo kunye nokuhlaselwa kwemisebenzi. Ngelo xesha, kukho ukuxiliswa kwe-ammonium, ebonakalayo kwingxaki yesistim. Kukho ezinye iingxaki.
Kunokwenzeka ukuba ulungelelanise amanqanaba e-urea ngokuqhuba unyango lweklasi kwisifo esisisiseko. Kubaluleke kakhulu kunyango kunye nokuthintela kukutya okufakwe ngokufanelekileyo.
