Izinhlobo zegazi ezisengozini yokuboshwa kwenhliziyo

Ucwaningo lwakamuva luveze ukuthi uhlobo lwegazi lomuntu lungamataniswa sengozini yokushaywa unhlangothi ngokushesha okubangelwa ukuvaleka kokugeleza kwegazi ebuchosheni, okwenzeka entsheni engaphansi kweminyaka engu-XNUMX.

Abacwaningi abavela eNyuvesi yaseMaryland School of Medicine, kanye nabanye abavela ezikhungweni ezingaphezu kuka-50 zesayensi, zezokwelapha nezemfundo emhlabeni wonke, benze lolu cwaningo lwezibalo, ngokusho kweSciTechDaily, becaphuna iphephabhuku iNeurology.

Abacwaningi bathole ukuxhumana phakathi kwe-stroke yangaphambi kwesikhathi nendawo ye-chromosome ehlanganisa isakhi sofuzo esinquma ukuthi uhlobo lwegazi luwu-A, AB, B noma O.

uhlobo lwegazi A

Baphinde baqinisekisa ukuthi abantu abasengcupheni enkulu yokushaywa unhlangothi kusenesikhathi yilabo abanohlobo lwegazi A, kanti mancane amathuba okuba yilabo abanohlobo lwegazi u-O, uma kuqhathaniswa nabantu abanesifo sohlangothi sekwephuzile kanye nabangakaze bashaywe yisifo sohlangothi.

Abacwaningi bathole ukuthi abantu abanohlobo lwegazi A basengozini ephezulu engu-16% yokushaywa unhlangothi ngaphambi kwesikhathi kunabantu abanezinye izinhlobo zegazi.

Abantu abanohlobo lwegazi O babemancane ngo-12% amathuba okuba nesifo sohlangothi uma kuqhathaniswa nalabo abanolunye uhlobo lwegazi.

Ingozi enesizotha

Kodwa abacwaningi bagcizelele ukuthi ingozi eyengeziwe yayinesizotha kakhulu, bephawula ukuthi abantu abanegazi lohlobo A akufanele bakhathazeke ngokuba ne-stroke ngaphambi kwesikhathi noma bahlanganyele ekuhlolweni okwengeziwe noma ukuhlolwa kwezokwelapha ngokusekelwe emiphumeleni yocwaningo.

UProfesa Kettner wachaza: “Isizathu sokwanda kwengozi yokuba nohlobo A lwegazi asikaziwa, kodwa cishe sihlobene nezici zokujiyisa igazi njengamaplatelet namangqamuzana ahamba emithanjeni yegazi kanye namanye amaprotheni ajikelezayo. , konke okuneqhaza ekuthuthukiseni amahlule. igazi".

Ucwaningo lwangaphambilini luphakamise ukuthi abantu abanohlobo lwegazi A basengozini enkulu yokuba namahlule egazi emilenzeni, okwaziwa nge-deep vein thrombosis.

Kodwa uProfesa Kettner ugcizelela ukuthi "kusobala ukuthi izifundo ezengeziwe zokulandelela ziyadingeka ukuze kucaciswe izindlela zokukhuphuka kwengozi yokushaywa unhlangothi", njengoba umkhawulo owodwa walolu cwaningo ukuntuleka okuhlobene kokuhlukahluka phakathi kwabahlanganyeli, nakuba imiphumela yakhishwa Ukuhlaziywa kwemiphumela Izifundo ezihlukene ezingama-48 kulo lonke elaseNyakatho Melika, eYurophu, eJapane, ePakistan nase-Australia.
