Yintoni unobangela we-hypoxia kwizigulana ze-corona?

Uphononongo olutsha lukhanyisele ukuba kutheni uninzi lwezigulana ze-COVID-19, nkqu nezo zingekho esibhedlele, zithwaxwa kukunqongophala kweoksijini enokukhula kwaye isoyikise ubomi babo kumanqanaba athile osulelo.

Uphononongo, olwapapashwa kwijenali ethi "Stem Cell Reports", kwaye lwaqhutywa ngabaphandi abavela kwiYunivesithi yase-Alberta, lukwabonisa ukuba kutheni ichiza elichasayo lokudumba "iDexamethasone" lunyango olusebenzayo kwabo bosulelwe yintsholongwane, ngokutsho iphephandaba, "Xpress yezoNyango".

Umbhali okhokelayo kolu phando, uShukrullah Elahi, unjingalwazi onxulumene neKholeji yezoNyango kunye naMazinyo, uthe: “Amanqanaba asezantsi eoksijini yegazi ebeyingxaki enkulu kwizigulana ze-COVID-19. Isizathu soku, sikholelwa ukuba, enye indlela enokwenzeka kukuba i-COVID-19 ichaphazela ukuveliswa kweeseli ezibomvu zegazi. ”

Kuphononongo olutsha, u-Elahi kunye neqela lakhe bavavanye igazi lezigulana ezili-128 ezine-COVID-19. Aba baguli baquka abo babekwimeko emaxongo nabangeniswe kwigumbi labagula kakhulu, abo baye baba neempawu ezilinganiselweyo baza balaliswa esibhedlele, nabo babenogulo olungephi lwesi sifo nabachitha iiyure ezimbalwa kuphela esibhedlele.

Abaphandi bafumanise ukuba njengoko esi sifo sisiya sisiba mandundu, iiseli zegazi ezibomvu ezingekakhuli ziyahamba zisiya kumjikelezo, maxa wambi zenze umyinge wama-60 ekhulwini weeseli zizonke ezisegazini. Xa kuthelekiswa, iiseli zegazi ezibomvu ezingekavuthwa zenza ngaphantsi kwe-1%, okanye hayi kwaphela, kwigazi lomntu osempilweni.

"Iiseli ezibomvu zegazi ezikhulayo zifumaneka kumongo wethambo kwaye asiqhelekanga ukuzibona kwi-circulatory system," u-Elahi wachaza. Oku kubonisa ukuba intsholongwane ichaphazela umthombo wezi seli. Ngenxa yoko, ukuze kuhlawulwe ukuncipha kweeseli zegazi ezibomvu ezisempilweni, ezingekavuthwa, umzimba uvelisa ngakumbi ngakumbi ukuze unike ioksijini eyaneleyo emzimbeni.”
