Platelets Ndivo chimwe chezvikamu zvikuru zvekushanda kwakanaka kweropa nemuviri wedu. Ivo varipo muropa uye basa ravo ndere gadzirisa zvikamu zvese zvakakuvara izvo zvinogadzirwa mukati memuviri, kuitira kuti kumisa kubuda ropa.
Ropa imvura uye yakakosha tishu nokuda kwemiviri yedu. Inotenderera mukati memitsipa yedu yeropa uye inotakura nhamba huru yezvinhu, iyo inonyanya kukosha iyo masero matsvuku eropa, masero machena eropa, uye maplatelet.
Ndeapi maplatelet?
Platelets zvakare vanonzi thrombocytes. Iwo masero anowanikwa muropa uye sebasa ravo guru ravanoita kugwamba kweropa. Platelets anobva ku megakaryocytes, sero guru rinoputsika richipa upenyu kumazana ema<em>platelet. Megakaryocytes zvinosikwa mumwongo zvoita kuti maplatelet apfuure muropa.
Platelets havana nucleus, saka havazokwanisi kubereka, uye nokudaro hupenyu hwayo huri pakati pe9 kusvika ku10 mazuva mukati memuviri. Maplatelets kana akwegura kana kukuvadzwa achabviswa nekutenderera kweropa kuburikidza nespleen.
Platelet mabasa
Ropa remunhu rine maumbirwo anoitwa a 45% masero matsvuku eropa uye 1% masero machena eropa. Iro muzana yemaplatelet ichiri yakaderera pane iyo muzana inotsanangurwa uye vachiri kutora chikamu chebasa guru.
Maplatelet anobatsira kutidzivirira kubva kune ese kubuda ropa kucheka kana chero rudzi rwekubuda ropa. Vane basa re vhara chikamu chakakuvara yetsinga idzodzo dzeropa kukwanisa kumisa kubuda kweropa. Ivo vanotobatsira coagulation kuitika kuitira kuti plugging iitike uye kusimbiswa kunoshanda zvakanyanya.
Sero dzvuku reropa, sero reropa rakapfava uye mune yegirini platelet. Mufananidzo wakatorwa kubva kuWikipedia
Matambudziko akabatanidzwa
Kuti ubatanidzwe nedambudziko nemaplatelet, ichafanirwa kubatanidzwa nayo kuderera kwenhamba yavo kana kuwedzera zvakanyanya. Nhamba yavo ichave iri pakati pe120.000-140.000 uye isingapfuuri 400.000-440.000 maplatelet per microliter. Kana paine kusaenzana kwenhamba idzi kakawanda, kuferefetwa kunofanirwa kuitwa kuti kuone chakonzera.
Kuwedzera kweplatelet
Kuwedzera kusina kujairika kwenhamba yavo kunogona kutungamirira ku inokosha thrombocythemia. Mwongo webhonzo unogadzira nhamba huru yemaplatelet pasina kusangana nemhando ipi neipi yekusagadzikana. Mapinduriro achaonekwa kubuda ropa zvakanyanya uye saka coagulation haizoitike. Muchiitiko ichi, inowanzotaurwa mushonga wekudzikisa nhamba yemaplatelet.
Reactive thrombocytosis chimwe chirwere chinogadzirwa munyaya iyi kune rumwe rudzi rwechirwere. Mwongo unobereka nhamba huru yeplatelet inogadzirwa nekuda kweimwe mhando yehutachiona kana shanduko, senge rheumatoid arthritis, kushaikwa kwesimbi, chimwe chirwere chematumbo kana kenza. Zviratidzo zvaro hazviwanzokonzera kuvhara zvakanyanya kana kubuda ropa zvakanyanya. Haitakuriwo chero rudzi rwekurapa, asi rinorapa chirwere chinokonzera.
Kuderera kweplatelet
Panogona kuva nezvikonzero zvakawanda zvekuderera kweplatelet. Inonzi thrombocytopenia uye zviratidzo zvayo zvinogonawo kuva non-normal coagulation yeronda, kunyangwe kazhinji kazhinji pasina shanduko.
General zviratidzo zvechirwere
Ganda rinogona kutipa humbowo hwerumwe rudzi rwekushandurwa kwenhamba yemaplatelet. Kubuda ropa ndiyo yambiro yezviratidzo izvi kwaanogona kuzviratidza mu a kubuda ropa zvakanyanya kubva mumazamu, tsvina, uye weti. Vakadzi vanogona kurasikirwa kukuru mukuenda kumwedzi uye kubuda ropa kwakawanda mumhino kunogonawo kuoneka.
Makwapa matsvuku anooneka pamakumbo ezasi, kunyangwe bumpu diki, kukuvara kana puncture inogona kukonzera mavanga eblue-black (ecchymosis kana purpura). Iyo yakaderera nhamba yeplatelet, iyo yakakura zviratidzo zvinogona kuitika.
Kuti uongorore iyo yakanakisa prognosis, zvinodikanwa enda kuna chiremba wemhuri saka unogona kuita ongororo yeropa (yakazara ropa kuverenga) uye ona kana pane kuchinja muhuwandu hwemaplatelet.
