Kuyini okuqukethwe kwamaplatelets egazini lomntwana onempilo?
Umkhuba wamaplatelets egazini ezinganeni ungenye yezinkomba ze-hematopoiesis enhle. Ukuphila kwala maseli egazi kuncane. Ngokwesilinganiso, izinsuku ezingu-7-10. Ngakho-ke, ama-platelet kumele avuselelwe njalo egazini ukuze agcine i-homeostasis. Amaseli amadala alahlwe yi-isibindi ne-pengu, futhi adonswa emzimbeni kanye neminye imikhiqizo ye-metabolic.
Kuye ngokuthi uneminyaka engakanani yengane, inani leplatelet egazini lakhe libuye lishintshe. Lokhu kulinganiswa ngamayunithi nge-millimeter cubic.
Ngemuva kwesampuli segazi, i-centrifuged, ihlukanisa i-plasma, bese ibala inani leplatelet.
Lapho echaza izivivinyo, odokotela bavame ukusebenzisa itafula, ebonisa ukujwayelekile kokuqukethwe kwamaplatelets egazini ezinganeni, kuye ngokuthi uneminyaka yabo.
Ngakho-ke, ingane esanda kuzalwa egazini iqukethe amaplanethi ayizinkulungwane eziyi-100 kuya ku-2020 ngamamitha ayi-cubic.
Kusukela ezinsukwini eziyi-10 zokuphila futhi kuze kube unyaka lesi sibonakaliso senza izinkulungwane ezingu-150-350, ezinganeni ezindala kunomnyaka owodwa - 180-320 eziyinkulungwane mm ngegazi le-cubic.
Yini engakhuphula futhi ephansi ama-platelet amazinga egazini athi?
Ngokuvamile, ngenxa yezizathu eziningi, inani leplatelet yengane egazini lingase liphakeme noma liphansi kunejwayelekile. Ngakho-ke, ngokukhulisa okuqukethwe kwabo ngaphezu kwemigomo ebekiwe, bakhuluma ngokuthuthukiswa kwe- thrombocytosis (ukubukeka kwe-erythema ebuhlungu ehambisana nokuvuvukala kweminwe), futhi nokuncipha kwe- thrombocytopenia. Lesi sifo sibhekene nokukhuphuka kwezinto ezithwala izitsha futhi kungaholela ekuthuthukiseni kwegazi eliphansi ngaphansi komphumela omncane kakhulu.
