Iiplatelet ziseli zegazi ngendlela yeeplate zegazi ezenza kwifom ebomvu. Umsebenzi oyintloko weeplatelets kukuthatha inxaxheba kwiinkqubo zegazi kunye nokuyeka ukuphuma kwegazi. Iiplatesti zibaluleke kakhulu ekukhuselweni okungaphelelwanga komzimba womntu.
Xa ukhulelwe, inani leplatelet kwigazi lomfazi lidlala indima ebalulekileyo. Ukuguqulwa kwamancinci kwiimpawu zabo eziqhelekileyo kwiingqungquthela eziqhelekileyo akubangeli ukwesaba, kodwa ukuphambuka okunamandla kunokukhokelela kwiingxaki ezinzulu.
Inani leeplatelet egazini lomfazi okhulelwe lizimisele ngokunika uvavanyo lwegazi jikelele.
Isiqhelo se-thrombocytes kumfazi ongeyena ukhulelwe ngumlinganiselo wee-150-400 zamawaka / μl. Isiqhelo somxholo we-thrombocytes kwabasetyhini abakhulelweyo bahluke kule xabiso ngo-10-20%. Ukuqhaqhazelwa kwezi ngongoma kwinqanaba elinye okanye kwelinye liqhelekile ngokukhulelwa.
Ngokuqhelekileyo inani leeplatelet ngexesha lokuthwala komntwana lihluka ngokungafaniyo, kuba yonke into ixhomekeke kwimimandla ethile yendalo yowesifazane ngamnye.
Ukubalwa kweeplatelet ekunciphiseni ngexesha lokukhulelwa
Ukuncipha kokuncipha kwinani leplatelet kunokuxhomekeka kwimeko yokuba ubomi babo bunciphisa kwaye ukusetyenziswa kwabo kwimizila yokujikeleza kwimizila yanda, kuba umthamo wesigxina segazi emzimbeni wesifazane okhulelweyo ukhula.
Ukunciphisa amanqanaba aseplatelet ngaphantsi kwesiqhelo ngokukhulelwa kuthiwa yi-thrombocytopenia. Ukunciphisa iiplatelets egazini ngexesha lokukhulelwa libonakalisa ngokubonakala ngokukhawuleza kunye nokulondolozwa kwexesha elide kwemivimbo, ukuphuma kwamanzi. Iimbangela ze-thrombocytopenia zizinto ezinjengezifo zokuzivikela komzimba, ukuphuma kwintsholongwane engapheliyo, ukungondleki kakuhle kwabasetyhini.
Ukwehla okukhulu kwiiplatelet ngexesha lokukhulelwa kubangela ingozi ekwandiseni ukuphuma kwegazi ngexesha lokubeleka. Eyona nengozi i-immune thrombocytopenia, njengoko umngcipheko wokuphuma kwegazi ngaphakathi komntwana ukwanda. Xa izinga leeplatelets ngexesha lokukhulelwa liphantsi kakhulu kunexesha eliqhelekileyo, ugqirha uhlala esenza isigqibo malunga necandelo elimisiweyo.
Ukwandisa kwinani leeplatelets ekukhulelweni
Ukuba ukhulelwe iiplatelets ezongeziweyo, ke le meko ibizwa ngokuba yi-hyperthrombocythemia.
Imeko xa iiplatelets ngexesha lokukhulelwa liphakama ngaphezu kwexabiso eliqhelekileyo,
Ngoko ke, inani leeplatelet ngexesha lokukhulelwa lihlala lihlolwe. Ixesha lokugqibela lenziwa ngokukhawuleza ngaphambi kokubeleka ukuze kugweme umngcipheko weengxaki ngenxa yokuphazamiseka kwegazi.
