Igazi elisuka emunwe linikezelwa kaningi. Kuyadingeka emva noma ngenkathi ukwelashwa kwezifo, ngaphambi kokuhlinzwa noma ngesikhathi sokukhulelwa, ukulawula izinga le-hemoglobin, eliqukethwe amangqamuzana egazi abomvu - ama-erthrocytes.
Abantu abaningi bayazi ukuthi uma i-hemoglobin iphansi, kusho ukuthi umzimba awunayo i-iron futhi kubalulekile ukugcwalisa izimpahla. Kodwa kuthiwani uma amangqamuzana egazi abomvu egazini ephakanyiswa, yiziphi izimbangela zalokhu, nokuthi ngabe ukwelashwa kuyadingeka yini ukunciphisa lesi sibonakaliso?
Inani lamaseli abomvu wegazi kanye nokujwayelekile kokuqukethwe kwabo egazini
Lawa maseli ayingxenye eqondile enkambeni yokuphefumula, njengoba ehambisa oksijeni emaphashini kuwo wonke umzimba, kanye ne-carbon dioxide ngendlela ehlukile. Ngakho-ke, ngokusebenza okujwayelekile kwazo zonke izitho, kuyadingeka ukuthi kube khona inani elithile lala maseli egazini.
Kukholelwa ukuthi okujwayelekile umuntu omdala ngalinye ilitha elilodwa lamaseli abomvu kufanele abe:
- kubesifazane - kusuka ku-3.7 ukuya ku-4.7x10¹²;
- kubantu, kusuka ku-4.0 kuya ku-5.3x10¹².
Amaseli abomvu abomvu egazini abizwa ngokuthi i-erythropy, futhi i-erythrocytosis ephakeme noma i-polycythemia.
Kungani kuhlaziywa kwegazi elibomvu amangqamuzana egazi?
Umuntu onakekela impilo yakhe ngokuqinisekile uyoba nesithakazelo sokuba kungani enezinga eliphakeme lamaseli abomvu egazini lakhe. Uma uqaphele lokhu, kufanele uthintane nesifo segazi esizobona izimbangela ezilandelayo zalesi sifo:
- ukungeneli okwanele kwamavithamini noma ukuntuleka kwabo ngenxa yokungasebenzi kahle kwesibindi;
- i-neoplasms eyenza ukukhiqizwa kwama-erythrocyte (i-hypernephroma, i-cerebellum hemangioma);
- i-hypoxemia (ukungabi khona kwe-oksijeni): engapheli ngezifo zamaphaphu noma okwesikhashana - lapho ephakama, lapho umoya ongavamile khona;
- ukungcola noma ukushisa ngokweqile, ikakhulukazi uma imithwalo esindayo isikhathi eside;
- ukuthatha imithi (isibonelo: i-steroids ne-corticosteroids);
- ukukhubazeka kwenhliziyo okutholile noma etholakalayo;
- I-erythremia - isifo segazi, lapho kukhona ukwanda okwenyuka kwamangqamuzana egazi abomvu ngenxa yezizathu ezingapheli;
- umsebenzi ongafanele wezinso nama-adrenals, okubangelwa u-erythropoietin kakhulu;
- i-tumor ebulalayo kanye nokusetshenziswa kwe-radiation therapy ukuze uyiphathe;
- ukusetshenziswa kwamanzi amabi aphezulu, okungukuthi, okuchloriniwe, engcolile noma obuningi kakhulu.
- ukungeneli okwanele kwama-enzyme okudingekayo ekugayeni, ngakho-ke umzimba kufanele ukhiqize amangqamuzana amaningi obomvu egazi ukuze ugaye ukudla;
- Ukubhema, ngenxa yokudlula kwe-carboxyhemoglobin.
Njengoba kunezimbangela eziningi ezibangela inani elidlulele lamaseli abomvu egazini, ingcweti kuphela enganquma ukuthi yini eyabangela le nqubo ngqo kuwe futhi ibeka ukwelashwa okudingekayo.
Amaseli obomvu aphakanyisiwe - ukwelashwa
Ngokwemvelo, yilapho inani eliningi lama-erythrocyte egazini elingaphathwa ngokwehlukana. Lokhu kungasuswa, kuphela ukuqeda izimbangela, okungukuthi, izifo noma izici ezivusa ukwenziwa kwamaseli engeziwe.
Kubalulekile ukulawula ikhwalithi yamanzi (ukuze kungabi khona i-chlorine eningi kakhulu) kanye nevolumu yotshwala ngosuku. Umuntu omdala udinga ukudla okungenani ilitha elilodwa, futhi ekushiseni okuphezulu kwemoya, ngisho nama-2 amalitha.
Uma kunezinkinga emsebenzini wesisu, faka izithelo nemifino ekudleni. Lokhu ngeke kusize kuphela ekulawuleni ukwenziwa kwamaseli abomvu wegazi ngokuthuthukisa inqubo yokugaya ukudla, kodwa futhi kuzokhuthaza ukubunjwa kwamaseli abomvu efomini elifanele.
Njengoba ukwanda kwenani lamaseli abomvu egazini kungukubunjwa kwe-thrombi, kwezinye izimo kunconywa ukuba kwenziwe izinqubo zokufaka igazi ngesizo lwezinyosi , ukuphanga noma ukucubungula.
