Kungani inombolo yamaseli obomvu anganda?
Izizathu zokuthi ingane ivuswa amangqamuzana egazi obomvu egazini, okuningi. Lesi simo semithi saziwa ngokuthi i-erythrocytosis. Kulesi simo, kuyisiko ukuhlukanisa izinhlobo ezimbili zokwephulwa okunjalo: ukwanda komzimba nokwemvelo kokuqukethwe kwama-erythrocytes.
Esikhathini sokuqala, ukwanda kwenzeka ngenxa yimuphi umphumela emzimbeni, isibonelo, ngenxa yokuphelelwa amandla kwamanzi. Ngakho ukungabi khona kwamanzi oketshezi emzimbeni kubangela ukunyuka okuncane kulezi zisele egazini.
Kodwa-ke, ngokuvamile ukuthuthukiswa kwalesi sifo kubangelwa izifo, ngenxa yalokho i-erythrocytosis ye-pathological iqala. Lokhu kungabonwa lapho:
- ukukhiqizwa kwamaseli abomvu ebomvu emasakeni (i-erythremia);
- izifo zezinso, amaphaphu, ezihambisana nokukhululwa kwesisindo esikhulu se-erythropoietin (izicubu zezinso, i-bronchitis ephazamisayo, i-asthma ye-bronchial);
- ukungabi ne-oxygen emzimbeni.
Lezi zinsuku zivame ukubonwa ezifweni zamaphaphu, okwenza kube nesidingo sokuba umzimba uvuselele ukungabi khona kwe-oksijeni ngokwandisa inani lamaseli abomvu aphetheyo.
Futhi, amangqamuzana egazi abomvu egazini lezingane ayenyuka futhi enesifo senhliziyo. Ezimweni ezinjalo, igazi elibhekene negazi lixutshwe ingxenye encane negazi eligcwele igazi eligcwele i-carbon dioxide. Ukuze ukhokhele ngokweqile kwe-CO2 emzimbeni, inani elikhulu lama-erythrocyte lenziwe ngokwezifiso.
Umkhuba wokuqukethwe kwama-erythrocytes emcintweni kanye nezimbangela eziholela ekukhuleni kwabo
Ngokuvamile, kucatshangwa ukuthi uma wenza u-urinalysis, inani lama-erythrocytes esampula lokuhlola akufanele lidlule u-2-4. Lapho lezi zibalo zidlulile, zithi:
- i-microhematuria - inani lama-erythrocytes emcinini ukuya ku-20 emkhakheni wombono, ngokubukeka umbala awushintshiwe;
- i-hematuria - inombolo ephezulu ye-erythrocytes, engakwazi ukubalwa, umchamo uthola umbala obomvu noma obomvu.
Izizathu zokuthuthukiswa kwalesi simo, lapho amangqamuzana ebomvu egazi emcimbini wengane ekhuphuka, angahlobene noku:
- izifo zesistimu ye-urinary ngokwazo;
- izifo zezinye izitho nezinhlelo zomzimba, lapho izinso zisabela ngendlela yokubonakala kwama- erythrocytes emcimbini (i-hematuria esebenzayo).
Ngakho-ke, ukuze unqume ukuthi kungani amangqamuzana egazi abomvu ekhuliswa enganeni, udokotela ubeka ukuhlolwa okuphelele, ecabangela izifo ezingapheli ezikhona.
