Kalula nje, ayini lawa ma-platelet?
Kulungile, cabanga ngale ndlela. Igazi lethu alikhiwanga yinto eyodwa kuphela. Lakhiwa izinhlobo ezintathu eziyinhloko zamaseli. Amangqamuzana abomvu egazi, amangqamuzana amhlophe egazi, kanye nama-platelet esikhuluma ngawo lapha. Amancane kakhulu futhi alula kulawa amathathu abizwa ngokuthi ama-platelet. Abanye abantu bawabiza nangokuthi '(ama-Thrombocyte)'. Mancane kakhulu kangangokuthi asikwazi ukuwabona ngaphandle kwe-microscope. Uma ekhona nje, okungukuthi, entanta egazini ngaphandle kokwenza lutho, abukeka njengezingcezu ezincane zepuleti. Kodwa-ke, uma umthambo wegazi usikiwe ndawana thize, uma kukhona ukulimala, lawa ma-platelet 'ayavuka' ngokuzumayo ngenxa yesignali evela ekulimaleni . Bese isimo sawo sishintsha, athatha isimo se-octopus enamagatsha asakazekile, futhi ashesha agijimele endaweni yokulimala bese eqala ukusebenza ukuze awuvale.Uyini umsebenzi oyinhloko wama-platelet egazi?
Umsebenzi obaluleke kakhulu noyinhloko wama-platelet egazi ukuvimbela ukuphuma kwegazi okungadingekile . Lokhu kubalulekile ukuze kusindiswe izimpilo zethu. Cabanga ukuthi isandla sakho sinqunywa ngommese. Ngemva kwesikhashana, ukuphuma kwegazi kuyayeka, ngoba izinkulungwane zala ma-platelet ziyahlangana futhi zinamathele ndawonye enxebeni, zakha i-mesh, futhi "zivale" inxeba. Lokhu sikubiza ngokuthi inqubo yokujiya . Leli khono yilona elisindisa izimpilo zethu ekuhlinzweni okukhulu, ukufakelwa izitho zomzimba, kanye nezingozi ezinkulu. Futhi, umsebenzi wala ma-platelet ubaluleke kakhulu lapho welapha iziguli ezinomdlavuza.

Check Availability →Lawa ma-platelet akheka kuphi? Akheka kanjani?
Ama-platelet akhiqizwa engxenyeni ethambile, ethambile yamathambo ethu. Lokhu sikubiza ngokuthi umnkantsha . Ama-platelet enziwa amangqamuzana amakhulu kakhulu abizwa ngokuthi "ama-Megakaryocytes" ngaphakathi kwalo mnkantsha. Lawa maseli amakhulu ahlukana abe yizicucu ezincane eziyizinkulungwane (ezingaphezu kuka-1000) ukuze akhe ama-platelet.Kalula nje, ama-platelet ayizingcezu ezincane eziqhekeka emangqamuzaneni amakhulu kakhulu emnkantsheni wethambo.I-hormone (Trombopoietin) isiza kakhulu ekulawuleni ukukhiqizwa kwala ma-platelet. Uma sekwenziwe futhi senezelwe egazini, isikhathi sokuphila se-platelet eyodwa siphakathi kwezinsuku ezingu-8 nezingu-10. Nakuba lawa angamaseli aphukile, aqukethe amaprotheni amaningi adingekayo ukuze kumiswe ukopha. Anamaprotheni ebusweni bawo asebenza njengeglue. Lawa yiwo awenza anamathele esilondeni futhi ahlangane namanye ama-platelet.
Iyini inani lama-platelet kumuntu ophilile?
Ngokuvamile, umuntu omdala onempilo kufanele abe nama-platelet aphakathi kuka -150,000 no-450,000 nge-microliter (inani elincane kakhulu, cishe ingxenye eyodwa kwesigidi yelitha) legazi. Ungathola ukuthi mangaki ama-platelet onawo ngokuhlolwa kwegazi okuphelele (i-CBC). Ngezinye izikhathi, lawa ma-platelet angaba ngaphansi noma aphezulu kunokujwayelekile. Azikho kulezi zimo ezinhle.- I-Thrombocytopenia : Ukwehla kwenani lama-platelet ngaphansi kuka-150,000. Uma lokhu kwehla kube yinani eliphansi kakhulu elingu-10,000 - 20,000, ngisho nesilonda esincane singabangela ukopha ngokweqile. Ukopha kungavela ekhaleni noma ezinsinini. Yilokhu futhi okwenzekayo kumkhuhlane we-dengue.
- I-Thrombocytosis: Inani lama-platelet angaphezu kuka-450,000. Lokhu kungasukela ku-500,000 kuya ku-1 million. Uma lokhu kwenzeka, amahlule egazi angakheka emithanjeni yegazi , avimbele ukugeleza kwegazi enhliziyweni noma ebuchosheni, okuholela ezimweni ezimbi njengokuhlaselwa yinhliziyo kanye nesifo sohlangothi .
Izifo ezingase zivele ezihlobene nama-platelet
Ngaphezu kokubalwa kwama-platelet aphansi noma aphezulu, kunezimo lapho ama-platelet esezingeni elifanele kodwa engasebenzi kahle. Ake sibheke izimo eziyinhloko.| Isimo sezokwelapha | Incazelo nezizathu |
|---|---|
| Ukungasebenzi Kahle Kweplatelet | Lapha, inani lama-platelet lingase libe elijwayelekile, kodwa abenzi umsebenzi wabo (ukugoqa igazi) ngendlela efanele. Lokhu kungabangelwa izici zofuzo, ubudala, imithi ethile, kanye nezinye izimo zezokwelapha. |
| I-Thrombocytosis Eyinhloko | Kulesi simo, umongo wethambo ukhiqiza ama-platelet amaningi ngaphandle kwesizathu noma ukulawula. Imbangela eqondile yalokhu ayaziwa okwamanje. |
| I-Thrombocytosis yesibili | Nalapha futhi, inani lama-platelet liyakhuphuka, kodwa imbangela ingenye inkinga yezokwelapha. Isibonelo, izimo ezifana ne-anemia (inani eliphansi legazi), ukutheleleka, noma umdlavuza zingabangela inani eliphezulu lama-platelet. |
| I-Thrombocytopenia | Kulesi simo, umongo awukwazi ukukhiqiza ama-platelet anele. Lokhu kungabangelwa ukuphuza utshwala ngokweqile, isifo sezinso, imithi ethile, umdlavuza (njenge-"Leukemia", "Lymphoma"), kanye nezimbangela zofuzo. Ukopha njalo ekhaleni kanye nokopha kwezinsini kuyizimpawu zalesi simo. |
Agcinwa kuphi ama-platelet?
Ngemva kokukhiqizwa emnkantsheni wethambo, lawa ma-platelet avame ukuntanta emithanjeni yegazi. Kodwa-ke, isitho emzimbeni wethu esibizwa ngokuthi i-spleen sigcina cishe ama-25% ama-platelet ukuze asetshenziswe ezimweni eziphuthumayo. Kufana 'nethangi lokugcina'. Esimweni esiphuthumayo, njengokuphuma kwegazi okukhulu, i-spleen ikhipha lawa ma-platelet agciniwe egazini.Nginganikela ngama-platelet egazi?
Yebo, kungenzeka nakanjani. Njengokunikela ngegazi, unganikela ngama-platelet kuphela. Lena inqubo ephephile ngokuphelele. Lokhu kwenziwa ngaphansi kokuqondisa kwabasebenzi bezokwelapha abaqeqeshiwe. Ama-platelet abaluleke kakhulu ekwelapheni iziguli ezinomdlavuza. Ngoba, ngesikhathi sokwelashwa okufana ne-chemotherapy, umnkantsha ungalimala futhi ukukhiqizwa kwama-platelet kungancipha. Ezimweni ezinjalo, ama-platelet anikezwa ngaphandle angaba usizo olukhulu ekusindiseni izimpilo zalezo ziguli.Umlayezo Wokuya Nawe Ekhaya
- Ama-platelet ayizingcezu ezincane zamangqamuzana egazini lethu ezisiza ekumiseni ukopha.
- Lokhu kukhiqizwa emnkantsheni wethu wamathambo.
- Inani lama-platelet omuntu ophilile liphakathi kuka-150,000 no-450,000 nge-microliter ngayinye yegazi.
- Inani lama-platelet elingaphansi kunelijwayelekile libizwa ngokuthi Thrombocytopenia'' kanti ukwanda kubizwa ngokuthi Thrombocytosis'', futhi zombili lezi zimo zingabangela izinkinga zempilo.
- Uma unenkinga ngenani lama-platelet embikweni wakho wokuhlolwa kwegazi , khuluma nodokotela wakho ngakho ngokushesha.
- Ukunikela ngama-platelet kuyisevisi yomphakathi ephephile kakhulu futhi esindisa impilo, ikakhulukazi ezigulini ezinomdlavuza.
