Urea egazini ngumkhiqizo wokuwohloka kwamaprotheni. I-Urea ikhiqizwa yisibindi inqubo yeprotheni synthesis futhi idonswa ngokusebenzisa izinso ngomchamo. Ukuze unqume izinga le-urea labantu, kuhlolwa i-blood test biochemical blood. Umkhuba we-urea egazini uhlobene nobudala nobulili: kwabesifazane kuncane kakhulu. Ulwazi oluthe xaxa mayelana nesimiso se-urea egazini labesifazane, ungafunda kulesi sihloko.
Izinga le-urea egazini - okujwayelekile kubantu besifazane
Amazinga e-Urea kwabesifazane abangaphansi kweminyaka engama-60 avela ku-2.2 kuya ku-6.7 mmol / l, kuyilapho emadodeni, umkhuba uphakathi kuka 3.7 no 7.4 mmol / l.
Lapho uneminyaka engama-60, isimiso samadoda nabesifazane silingana futhi silinganiselwa ku-2.9-7.5 mmol / l.
Izinto ezilandelayo zithinta okuqukethwe kwe-urea:
- umsebenzi wesibindi;
- isimo sokusebenza sezinso;
- izinga lama-amino acids elibandakanya amaprotheni emzimbeni.
Okuqukethwe kwe-urea egazini labafazi abangaphansi kwesimiso
Uma ngenxa yokuhlaziywa kwezinto ezinokwemvelo kwamanzi owesifazane une-concentration ephansi ye-urea egazini lakhe uma kuqhathaniswa nokujwayelekile, izizathu zalolu shintsho zingaba:
- ukudla, kanye nokukhishwa ekudleni kwemikhiqizo yezilwane (inyama, amaqanda, ubisi) nenhlanzi noma indlala yesikhathi eside;
- isifo sesibindi (isifo sofuba, isifo se-cirrhosis, i-hepatodystrophy, i-coma e-hepatic);
- i-acromogy - i-hormonal pathology, ebonakala ngendlela yokwanda okungavumelani kwezitho zomzimba;
- ukuphazamiseka emthonjeni wegciwane;
- ubuthi ngamakhemikhali aqukethe i-arsenic ne-phosphorus;
- ukushaywa indiva - ukunciphisa ukuncishiswa kwama-amino acid emathunjini.
Ngokuvamile kukhona ukwehla esimweni esivamile se-urea egazini labesifazane abakhulelwe. Lokhu kushintshwe ngenxa yokuthi amaprotheni omama asetshenziselwa ukwakha umzimba wengane engakazalwa.
Ukuhlushwa okuphezulu kwe-urea egazini
Amazinga e-urea amaningi ayabonisa ukugula okubi kakhulu. Ngokuvamile, izinga eliphezulu lezinto ezibonakalayo libhekwa ezifweni ezinjenge:
- ukuhluleka kwezinso nezinye izifo zezinso (i-pyelonephritis, i-glomerulonephritis, isifo sofuba sezinso, njll);
- ukwephula ukuphuma komchamo njengomphumela we-urolithiasis, isisu esiswini, njll;
- i-infarction ye-myocardial ne-heart failure;
- ukuvimbela emathunjini;
- ukuphuma kwamathumbu;
- i-hyperthyroidism;
- i-leukemia;
- isifo sikashukela (ngenxa yokuphazamiseka kwe-urea excretion);
- i-leukemia ;
- ukushisa amanxeba;
- isimo sokwethusa;
- ubuthi ngezinto ezinamakhemikhali, i-oxalic acid ne-phenol;
- ukuwohloka okukhulu komzimba ngenxa yokuhuda noma ukuhlanza.
Futhi, ukuhlushwa okuphezulu kwe-urea egazini kungaba umphumela wesimo esiqinile kakhulu esingokwenyama (kuhlanganise nokuqeqeshwa okujulile) noma ukudla okuphezulu kwamaprotheni ekudleni. Ngezinye izikhathi izinga le-urea landa ngenxa yokuphendula komzimba ngabanye ukuthatha imithi, kubandakanya:
- anabolics;
- i-corticosteroids;
- ama-antibiotics;
- sulfonamides.
Ukwanda okukhulu kwe-urea emithi kubizwa ngokuthi i-uremia (hyperaemia). Lesi simo sibangelwa ukuthi ukuqoqwa kwamaseli kagesi kuholela ekwandeni nasekudakaleni kwemisebenzi. Ngesikhathi esifanayo, kukhona ukuxiliswa kwe-ammonium, okubonakala ku-disorder yesimiso sezinzwa. Kungase kube nezinye izinkinga.
Kungenzeka ukuthi ujwayelekile ukwenza amazinga e-urea ngokuqhuba ukwelashwa kohlelo lwesifo esiyisisekelo. Okubaluleke kakhulu ekunakekeleni nasekuvinjeni kuyidla lokuhlelwe kahle.
