Maplatelet: ndozvakajairwa vana. Analysis ropa maplatelet: achiongorora zvaive uye kududzira zvabuda

masero eropa vane zvikuru siyana. Mumwe nomumwe wavo anoita zvakasiyana basa, zvainanga kuchengetedzwa uye dzigadziridzwe dzomuviri mabasa. Nokuti kudzivirira nhengo kubva ropa kurasikirwa otvetstvennny maplatelet.

Kunyanya kukosha kuona uwandu masero aya kuvana, sezvo ivo vari tichikurumidza kukuvara ropa kurasikirwa kana vanogona kukanganisa muviri vakasimba zvikuru kupfuura munhu mukuru. Saka chii maplatelets, uye chii mwero platelet muvana?

Ndezvipi masero aya?

Maplatelet anoreva masero, kuona kuvimbika mudziyo masvingo. Vari aumba kubva megakaryocyte - masero hofori kuine nuclei. Paumbwe ropa maplatelet (thrombocytes zita rechipiri) anotora nzvimbo yokuzviparadzanisa yavo hofori masero.

Midziyo circulates vanenge 70 muzana aumba masero ose uye 30 muzana ndiyo chirwatata. Pane zviri kuitika uye kuparadzwa masero aya.

Maplatelet havana neerekitironi, uye saka havagoni zvichiberekana.

cytoplasm yavo unotora dzinoverengeka makemikari uye zvinhu zvinoita kuti paumbwe thrombi, apo masero uye vaite mabasa avo.

Maplatelet vane pfupi-akararama - kubva pamazuva 7 kusvika 10, pashure izvo tsva masero vanoparadzwa ne macrophages.

Platelet wokuyera muvana anogara zvishoma kupfuura nedzevakuru. Izvi imhaka chinoshingaira muviri muviri wemwana. Ndezvipi zvinoitwa tsika nhamba masero aya?

zvinoitika mumatunhu

Chii zvakafanana svikiro vagara vandifungira masero eropa ashayise maplatelet? Ndozvakajairwa muvana kazhinji zvinotevera neeSultan:

• In achangoberekwa vacheche, nhamba maplatelet zvinowanzoita pakati 100 uye 420 * 10⁹ masero por fő ropa.
• Pazera rimwe gore zvishoma platelet count inowedzera zvishoma - kusvika 150. The vaifanira nekusiyana, ipfupi kusvika 350.
• Pashure pegore indekisi mwana platelet-hwokurara zvakangofanana akura - 180-320 * 10⁹ paminiti fő ropa.
• Ndava nemakore mashanu, dzimwe nguva pane chakajairika - change maplatelet (ndozvakajairwa vana 5 makore haana kumbosiyana kubva nhamba mukuru, asi masero kuva vanoshingaira, ndokusaka kukura trombopaty vakachengeta). Fani iyi rinotsanagurwa chiremba crosshairs wechipiri. Nokuda kutonga pamusoro neutrophils zvinogona kukonzerwa kuzvimba pezvakaitwa pamwe activation zvenhema maplatelet.

Zvinofanira kurangarirwa kuti kana bvunzo ropa Hardware uye Chinyorwa platelet kuverengwa mwero ropa mwana anogona siyana zvishoma. Naizvozvo, otomatiki kukarukureta pakati kufadza bvumidzwa kuipa tsika anosvika 500 ndiro vachangoberekwa uye kukwira kusvikira 400 panguva mwana makore.

Sarudzo dzinofanira kupiwa zvose Chinyorwa kuverengwa: kashoma kuti vanokanganisa uye zvakawanda - kuti zvakarurama zvawanikwa.

Sei vakaumba?

Paumbwe ropa maplatelet kumbowanikwa mumwongo. The tateguru masero aya - megakaryocyte - hofori muchitokisi. Riri pakati masero endothelial uye fibroblasts. By nokufumura masero kubva kunze anosiiwa nezvimedu megakaryocyte (cytoplasm chobudira pakati akapoteredza makamuri uye nokudaro otshnurovyvaetsya).

Vachipinda muropa, maplatelet tenderera kuburikidza nawo kusvikira wasvika hunenge mugove mudziyo (zvakakosha kuti endothelial kukuvadza). Kugadzirisa ipapo maplatelet kukonzera vamwe humoral pezvakaitwa zvinozoguma muna situ vakaumba fibrotic maronda muviri pamusoro zviri rakachengetedzwa uye maplatelet itsva. Saka kuumbwa chena, ipapo tsvuku thrombus wokutanga.

Pfungwa inotungamirwa masero ari mumwongo kunoitika zuva nezuva, achivabvumira kuramba inowanzotorwa uwandu. Chero mwongo kunobatsira kuderedza kana kuwedzera uwandu kwamahwendefa.

uwandu muchitokisi kuchinja

Sezvo chikazozikamwa, parameters zvose womukati kwezvakatipoteredza womunhu muviri vanochinjwa pasi pokudzora avo kana zvimwe zvikonzero. Vakawedzera kwevari platelet rinonzi thrombocytosis. Inogona rakakamurwa nesekondari. Primary thrombocytosis anokonzerwa zvakananga kuparadzwa mumwongo. It zvinoenderana yechipiri comorbidities.

Akaderedza platelet count inonzi leukopenia. Uyewo thrombocytosis, rakakamurwa nesekondari.

Zvakakosha kunzwisisa sei maplatelet muvana siyana. Norm (tafura zvinosanganisira kuipa tsika uye kutsauka ukuwo zera) inogona zvakasiyana kune divi uye dzimwe nguva anoonekwa nepasipo. Ndokusaka zvichikosha kuziva zvichibvira zvarakasiya kubva ndozvakajairwa muvana nokuda yakarurama zvawanikwa. tafura riri sezvinotevera.

Saka nei kushandura mashoko akaturikidzana nemasero? Zvakakosha kugadzirisa nyaya iyi zvizere.

Zvikonzero kuwedzera kwevari maplatelet

Sei zvino anogona kuwedzera maplatelet? Ndozvakajairwa muvana vanogona siyana nokuda kwezvikonzero zvinotevera:

• Myeloproliferative chirwere (kazhinji mwongo neoplastic maronda pamwe nokuwedzera zvayo dzichipfekeka basa). Kuwedzera kwenhamba maplatelet kunoitika kakawanda kuwedzera mamwe masero.
• Kazhinji anogumbura zvirwere zviri chisingaperi hunhu - RA kwemajoini chirwere (yokupara yemajoini), TB.
• Ropa. Pane kushanda platelet overproduction kumisa kurasikirwa ropa.
• Glucocorticosteroids. mahormone ava kushandiswa kwenguva refu (semuenzaniso, zvikuru asima) kukonzera kuti zvinenge zvose yakaputsika dzinongoitika urongwa Zvisinei thrombocytosis kunogona kuitika.

Maplatelet dzakakwirira kupfuura dzose mune mwana anogona kuonekwa somugumisiro zvirwere ropa system (semuenzaniso, kana eritremii).

Kuderedza uwandu maplatelet

Sezvambotaurwa, pachiyero pakugwamba masero anogona kudukupiswa. Nei izvi zvichiitika?

Maplatelet vari pazasi dzose ari mwana vari kuchengetwa kakawanda panguva nezvirwere ropa - aplastic kupererwa neropa uye neleukemia. Uye kwakaderedza nhamba masero ari zvirwere.

Nhaka zvirwere. Izvi zvinosanganisira Uiskotta-Aldrich urwere, Fanconi, histiocytosis. Zviri zvirwere izvi kutungamirira chokwadi kuti vana yokuderedza maplatelet. Norma vana vanenge harimbowaniki, maplatelet pamwero anogara ipfupi.

Kumwedzi. Ndivo chinokonzera thrombocytopenia pavasikana vachangobva kuchengetwa kutevera. chinokosha zvinoderedza pachiyero masero zvinogona kuchengetwa pamberi normalization yatinofema.

Heavy simbi chepfu. The inonyanya kutungamirira chepfu (somuenzaniso, nyaya apo mwana kwakaitika chepfu iyi sezvo pamusana kwemvura yacho vapor kubva Wallpaper itsva).

Kunyanya vana

Platelet indices vari normalized kune zvatinosiita rimwe gore, asi panguva neonatal nguva hwomwana ropa gadziriro iri kuwana zvimwe zvachinja.

Kana maplatelet takatsunga, mwero vana kungachinja zvishoma kuti gore. Somuenzaniso, panguva maawa mashanu woupenyu ropa mwana rekutanga akacherechedza vanenge mamiriyoni 215 maplatelet. Mumazuva mashanu okutanga, nhamba iyi zvinoderedza, uye pakazopera 5 Mazuva kuwanda rinomira pachiyero mamiriyoni 175. Rakanga riri 5th zuva pane kuchinja muropa - padanho dzinosiyana kwete chete platelet asiwo leukocyte (vanonzi "chiremba chigero" - kuyambuka lymphocytes uye neutrophils). About kuwanda maplatelet akagadzikana pamwe regumi zuva - kanenge miriyoni 100 masero (100-420 * 10⁹).

Maererano anova 180-320 * 10⁹ pavanokura nhamba yavo kunowedzera zvishoma, uye kwerinenge gore.

How kuziva maplatelet?

Kuziva nhamba ropa maplatelet vachishandisa bvunzo ropa. Kuiita chero kiriniki kana rabhoritari vakagadzirira pamwe zvakakodzera michina.

anofanira kufungawo hwomwana zera iri kuongorora. Zvinofanira kurangarirwa kuti, kana maplatelet takatsunga, mwero vana pasi gore rimwe, kureva wayo yakaderera, ndizvo chaizvo pasi. Panicking chete nyaya kana chimbadzo idukusa 100.

Zvairatidza kuti Mukududzira masero awedzerwa ropa kana, Ukuwo, vachinyanya nokukurumidza thrombus inotungamirwa.

Sezvataurwa pamusoro apa, kana maplatelet takatsunga, mwero vana vanogona-chinja zvishoma zvichienderana pamusoro kuverengwa nzira. Kana kushandisa imwe zvoga count, yokumusoro panogumira dzose ndiko zvishoma kupfuura panguva Chinyorwa kuverengwa. Izvi imhaka yokuti mudziyo anotora kunyange zviduku clots ropa sezvo vakawanda thrombi, uye munhu ari kuverenga - sei mumwe muchitokisi.

Kuwedzera Pakusarudza uwandu masero zvinogona kuongororwa uye dzavo dzichipfekeka basa. Kuti aite izvi, dzarakagadza mumwe kudzidza - coagulation. It rinogona kuona hadzina kufambiswa zvakanaka muzvinyorwa, kunyange kana mwero maplatelet muropa mwana rakazivikanwa.

Mukana kuchinja kwomuzvarirwo tsika?

Nokuti chii anosarudza padanho ropa thrombogenic zvinhu? Kutsunga kwavo kunokosha zvinotevera nyaya:

• Low kwevari masero kunoita kuti ngozi ropa. Pamusoro okutambirwa kukuvara kunowedzera zvikuru ndingangokuvara hombe nokurasikirwa neropa (uye nokuda kurasikirwa nomwana, kunyange shoma ropa kunogona kuurayisa). Kazhinji harbingers Sero pamwero rutapudzo vari mavanga paganda kunyange pashure chiedza kuonana naye. Vakati sokuti zvakafanira kuti kuedzwa maplatelet.
• Kuwedzera mwero masero ari yakawedzera thrombus inotungamirwa, izvo zvinogona kukanganisa kufamba kweropa vakawanda (kuwedzera mukana wokuti thrombosis kwaizotevera sitiroko, chemwoyo, kana necrosis).

Ndokusaka zvichikosha kutsanangura humboo zvinhu ropa.
