Ama-platelets amangqamuzana egazi ngesimo samapuleti egazi abumba emnothweni obomvu. Umsebenzi oyinhloko wamaplatelets ukuhlanganyela ezinkambeni zegazi coagulation futhi bayeke ukuphuma. Ama-Platelet abaluleke kakhulu ekuvikelweni okungenasidingo komzimba womuntu.
Ekukhulelweni, inani leplatelet egazini likawesifazane lidlala indima ebalulekile. Ukushintsha okuncane kwamagugu abo azungeze izilinganiso ezivamile akubangele ukwesaba, kodwa ukwehluka okuqinile kungaholela ezinkingeni ezinkulu.
Inombolo yamaplatele egazini lomfazi okhulelwe inqunywa ngokunikeza ukuhlolwa kwegazi jikelele.
Umkhuba we-thrombocytes owesifazane ongeyena okhulelwe kungumthamo wezinkulungwane ezingu-150-400 / μl. Ukujwayelekile kokuqukethwe kwe-thrombocytes kwabesifazane abakhulelwe kuhluke kule nzuzo ngo-10-20%. Ukuqothula ngaphakathi kwalezi zimiso ngandlela-thile noma okunye kuyinto evamile yokukhulelwa.
Ngokuvamile inani lamaplatele ngesikhathi sokubeletha kwengane lihluka ngokungafani, ngoba konke kuxhomeke ekuziphatheni komuntu ngamunye wesifazane.
Ukunciphisa inani leplatelet ngesikhathi sokukhulelwa
Ukunciphisa kancane ekubaleni kweplatelet kuncike ekutheni isikhathi sabo sokuphila sinciphisa futhi ukusetshenziswa kwabo ekujikelezeni komonakalo kuyanda, ngoba ivolumu yegazi egazini lomzimba okhulelwe uyakhula.
Ukunciphisa amazinga weplatelet ngezansi okujwayelekile ekukhulelwe kubizwa ngokuthi i-thrombocytopenia. Ukunciphisa ama-platelet egazini ngesikhathi sokukhulelwa kubonakala ngokubonakala okusheshayo nokulondolozwa isikhathi eside kwemivimbo, ukopha. Izimbangela ze-thrombocytopenia zingaba yizici ezifana nezifo zokuzivikela ngegciwane lesandulela ngculazi, ukuphuma kwegazi okungapheli, ukudla okunomsoco kwabesifazane.
Ukuncipha okukhulu kwamaplatelet ngesikhathi sokukhulelwa kuholela engozini enkulu yokwenza ukuphuma kwegazi ngesikhathi sokubeletha. Ikingozi kakhulu i-thrombocytopenia ye-immune, njengoba ingozi yokuphuma kwangaphakathi kwengane isanda. Uma izinga lamaplatelets ngesikhathi sokukhulelwa liphansi kakhulu kunokujwayelekile, udokotela ngokuvamile wenza isinqumo mayelana nesigaba sokugcina.
Ukwandisa inani lamaplatelets ekukhulelwe
Uma ukukhulelwa kuyiplatelet eyandisiwe, le nkinga ibizwa ngokuthi i-hyperthrombocythemia.
Isimo lapho izinga lamaplatelets ngesikhathi sokukhulelwa likhuphuka ngaphezu kwamanani ajwayelekile,
Ngakho-ke, inani lamaplatelet ngesikhathi sokukhulelwa lihlale lihlolwe. Isikhathi sokugcina senziwa ngokushesha ngaphambi kokubeletha ukugwema ingozi yezinkinga ngenxa yokuphazamiseka kwegazi.
