Yintoni umxholo weeplatelets egazini lomntwana onempilo?
Isiqhelo seeplatelets egazini kubantwana ngenye yezinto ezibonisa i-hematopoiesis enhle. Ubomi beli seli seligazi. Ngokomyinge, iintsuku ezingama-7-10. Ngoko ke, iiplatelet mazihlaziywe rhoqo kwigazi ukuze kugcinwe i-homeostasis. Amaseli endala ayalahlwa yi-isibindi kunye ne-spleen, kwaye adululwa emzimbeni kunye nezinye iimveliso ezixubileyo.
Ngokuxhomekeke kwiminyaka yomntwana, isibalo seplatelet egazini lakhe sitshintsha. Oku kulinganiswa kwiiyunithi nge-millimeter cubic.
Emva kwesampululelo segazi, i-centrifuged, ihlula i-plasma, leyo ibalwa inani leplatelet.
Xa ukuchazwa kweemvavanyo, oogqirha basebenzisa itafile, ebonisa umxholo weeplatelets egazini kubantwana, kuxhomekeke kwiminyaka yabo.
Ngaloo ndlela, umntwana osanda kuzalwa egazini uqulethe iiplatelet eziyi-100-420 zeekhabhi nganye.
Ukususela kwiintsuku ezili-10 zobomi kwaye ukufika unyaka lo mqondiso wenza ama-150-350 amawaka, kubantwana abadala kunama-1-180-320 ngamawaka nge-mm yegazi le-cubic.
Yintoni enokuphakamisa kunye namazantsi epletletlet amanqanaba egazini?
Ngokuqhelekileyo, ngenxa yezizathu ezininzi, inani leplatelet lomntwana kwigazi lingaba phezulu okanye liphantsi kuneqhelekileyo. Ngoko, ngokunyusa umxholo wabo ngaphezu kweemimiselo ezisisiseko, bathetha ngokuphuhliswa kwe- thrombocytosis (ukubonakala kwe-eerythma ebuhlungu ehamba kunye nokuvuvuka kweminwe), kunye nokuhla kwe- thrombocytopenia. Isi sifo sokugqibela sibonakaliswe ukugqithisa kweempahla kwaye kunokukhokelela ekuphuhlisweni kwesisu esincinci kwisiphumo esincinci.
