Usana lunamaseli obomvu

Ukuze kuqinisekiswe ukuba ngaba iiseli zegazi ezibomvu egazini zonyuka kumntwana, kuyimfuneko ukwazi ixabiso lemiqathango yesigamitha. Umxholo wabo uhluka ngobudala, kodwa akuxhomekeke kwisini somntwana. Ngoko, ngokomzekelo, kwiintsana ezi zizalwayo zilingana ne-3,9-5,5х10 * 12 / l, kwaye kubantwana abaneminyaka engama-6 ukuya kwe-12 ubudala, yi-2,7-4,8х10 * 12 / l.

Ngenxa yeliphi inani lamaseli obomvu okwandayo?

Izizathu zokuba umntwana ukhuliswe amangqombela egazi abomvu kwigazi, eninzi. Le meko yonyango ibizwa ngokuba yi-erythrocytosis. Kule meko, kuyisiko ukuhlukanisa iintlobo ezimbini zezophulo-mthetho: ukwanda komzimba kunye neentsholongwane kumxholo we-erythrocytes.

Kwimeko yokuqala, ukwanda kwenzelwa ngenxa yimuphi umphumo emzimbeni, umzekelo, ngenxa yokudambiswa kwamanzi. Ngoko ukungabikho kwamanzi emzimbeni kubangela ukwanda kancinci kwezi seli egazini.

Nangona kunjalo, ngokuqhelekileyo ukuphuhliswa kwesi sifo kubangelwa zizifo, ngenxa yoko i-erythrocytosis ye-pathological development. Oku kuya kuphawulwa xa:

• ukwanda kwemveliso yeeseli ezibomvu zegazi kwi-bone yomnatha (erythremia);
• izifo zeentso, iimiphunga, ezihamba kunye nokukhululwa kwesantya sokwanda kwe-erythropoietin (iisifo zeengso, isifo se-bronchitis esivimbelayo, i-asthma ye-bronchial);
• ukungabikho kwe-oksijini emzimbeni.

Olu hlobo lugqithiso luhlala luboniswa kwizifo zemiphunga, okubangela ukuba imfuneko yokuba umzimba uhlawule ukungabikho kwe-oksijini ngokunyusa inani leeseli ezibomvu ezithwalayo.

Kwakhona, iiseli ezibomvu zegazi kwigazi lomntwana zinyuka kwaye ziphosakele ngentliziyo. Kwiimeko ezinjalo, igazi legazi lixutywe ngokukodwa kunye negazi elimnyama, elizaliswe ne-carbon dioxide. Ukuze kuhlawulelwe imali engaphezulu kwe-CO2 emzimbeni, inani elikhulu le-erythrocyte lenziwe.

Isiqhelo somxholo we-erythrocyte kumchamo kunye nezizathu ezibangela ukwanda kwawo

Ngokuqhelekileyo, kucatshangelwa ukuba xa wenza u-urinalysis, inani le-erythrocytes kwisampuli yokuvavanya akufanele lidlule ngaphezulu kwe-2-4. Xa la manani adlula, athi:

• i-microhematuria - inani le-erythrocytes kumchamo ukuya kwimizuzu engama-20 kummandla wombono, ngokubonakalayo umbala awuguqulwa;
• i-hematuria - inani eliphezulu le-erythrocytes, elingenakubalwa, umchamo ufumana umbala obomvu okanye obomvu.

Izizathu zokuphuhliswa kweli bakala, xa iiselom zegazi ezibomvu kumchamo womntwana zonyuka, zinxulumene nale:

• izifo zendlela yokucoca;
• izifo zezinye izitho kunye neendlela zenyama, apho iinjongo zisabela ngendlela yokubonakala kwe- erythrocyte emcini (i-hematuria esebenzayo).

Ngaloo ndlela, ukuze kuqinisekiswe ukuba kutheni amangqamuzana egazi abomvu akhulelwa kumntwana, ugqirha ubeka uviwo olupheleleyo, ngokuqwalasela izifo ezingapheliyo.
