Maplatelet: mwero vanhu muropa

Maplatelet - a non-yenyukireya masero ose idenderedzwa chimiro ane dhayamita pamusoro 2-4 microns (micrometer). Izvi masero, kuwedzera kune leukocytes uye maplatelet vari corpuscles ropa. Ndivo vakadanwa maplatelet. Unorema muropa vanoumba maplatelet vakura - vanenge 87% foni yavo kare - 4.5% uye muduku kana saibva - 3.2%. ari kuibvisa munguva maplatelet paavhareji kunotora 8 mazuva. Vari muropa 9 kusvika 11 mazuva maplatelet.

Ndozvakajairwa varume, vakadzi uye navana vachava siyanei. Uyezve, zvichienderana nemakore anenge uyewo kuchinja. Vakawanda ropa kuongorora pamwe leucocytes, Chizenga, erythrocyte sedimentation mwero (ESR) uye leukocytic payakavakirwa zvinosanganisira nechiidzo akadai maplatelet. Normal munhurume masero aya anobva 180 kusvika bhiriyoni 400 pamusoro fő.

Zviripiko akaumba uye kuparadzwa?

Maplatelet vari vakaumba masero makuru megakaryocytes, izvo zvinenge zvachose akazara cytoplasm. Masero ichi chikuru pamusoro mwongo. Masikati, muviri aumbwa vanenge zviuru 70 maplatelet itsva - maplatelet. Small zvimedu megakaryocyte cytoplasm vanoparadzaniswa uye kupinda muropa - akaumba maplatelet. Zvadaro, masero aya vachikura, vaite mabasa avo, uye muna 9-11 mazuva rakaparadzwa chirwatata. muviri Iri basa achisiya ropa vakaumba zvinhu pamwe worutsanga chivakwa, makore okuva.

Imwe megakaryocyte inogona kuumbwa pamberi 8000 maplatelet. Nokuti kukura mwongo masero mumuviri sei zvikuru kemikari - thrombopoietin, riri synthesized ari chiropa, itsvo, uye skeletal tsandanyama. Kubva ipapo kuburikidza muropa naro anopinda dzvuku mwongo. Uye anoita kuti paumbwe megakaryocytes uye maplatelet. With kuwedzera ropa maplatelet kunoitika chinovhiringidza pamusoro kwetunhu thrombopoietin kemikari.

vasiri ehupfumi

Maplatelet basa rinokosha mune vasiri kwendangariro. Yavanobata zvinotevera mabasa:

• Initial vanorega ropa.
• Kuramba vascular matauriro uye permeability.
• Unodzivirira kuita.
• Pamwe chete leukocytes zvinobatanidzwa kubvisa anogumbura kwendangariro.
• Kuramba ropa iri mvura mamiriro.

Asi vakawanda vakaratidza zvavo hemostatic ushande. Kana mudziyo ropa wakaremara dzepanguva kuderedza lumen. Maplatelet kuwadzana collagen (coalescence yavo kunoitika) uye ropa clot aumbwa iyo inosimudzira hemostasis.

Chii rinokanganisa platelet uverenge?

Ngationei kuti chii kunokanganisa nechiidzo akadai maplatelet. Ndozvakajairwa vanhu ndiko zvishoma kupfuura kuti vakadzi nevana. On platelet Counts, pakati pezvimwe zvinhu, mune vose vana nevakuru kukanganiswa zera. Saka, muna achangoberekwa chakaipa-siyana maplatelet rakanyatsojeka rakafara uye anoda kubatsira kubva 100 kusvika 420 x 10 ⁹ / L (bn / l). kushanduka uku chokuita chokwadi kuti kweropa negadziriro vachangoberekwa riri kusagadzikana chaizvo uye maplatelet, uyewo mamwe masero eropa, ivo vanoshingaira kutanga uye kufa. Izvi anopfuurira kuti rimwe gore.

Kuwanda maplatelet muropa angava pamwaka ndatsamwa, vakawedzera pashure zvikuru mumuviri nesimba uye vane nokufamba nezuva.

platelet wokuyera varume, vakadzi, nevana

Uzive mitemo kuti varume, vakadzi uye navana, zvichienderana nezera kunogona kuva tafura pazasi.

Vamwe zvinyorwa akaratidza kuti mwero platelet nevanhu vanosvika 320 x 10 ⁹ / l. Hazvina zvishoma chikare mashoko.

Maplatelet: mwero nevanhu

Kutura kukosha anogona kuva akasimba pabonde pashure pemakore 60. Zvichienderana nemakore vamwe vakawanda Kuongororwa kweropa parameters angachinja. Izvi zvinoshandawo chiyero yakadai, sezvo maplatelet. Ndozvakajairwa nevanhu pamusoro zera parameter ichi raanotaura patafura.

Vakura, nhamba maplatelet vave zvishoma yakaderera. tafura iyi inoratidza zvakajeka sei dzinosiyana-siyana zvichienderana nemakore inoenzanirana chinoratidza sezvo maplatelet. Ndozvakajairwa nevanhu makore 60 okuberekwa ipfupi zvishoma zvichienzaniswa zvinokosheswa vechidiki.

Ko rakawedzera pamwero maplatelet?

The vakawanda Kuongororwa ropa , pamwe Chizenga, leucocytes, erythrocyte sedimentation mwero uye leukocyte count chinhu chinokosha chakarurama, uye maplatelet. Normal varume vane ropa ravo kusvikira 400, vakadzi - vanosvika 380 x 10 ⁹ / l. Kana mufananidzo uyu yakakwirira zvikuru, zvino mamiriro inonzi thrombocytosis. Izvi zvinogona kukonzera rakawedzera kweropa. Asi hazvina symptomatically richiratidzwa. Kazhinji kwakaratidza zvikuru netsaona - panguva wemauto ropa bvunzo munguva purogiramu vaongo-. Thrombocytosis anogona kuitika pasi zvinotevera ezvinhu:

• Oncological kwendangariro.
• Mielofiboz.
• Chirwere anogumbura kwendangariro.
• Zvirwere zvinotapuriranwa.
• The postoperative kumwedzi.
• Eritromiya (chirwere neleukemia).
• Pashure nokubviswa chirwatata (splenectomy).
• Kana simbi kushaikwa kupererwa neropa.
• Somugumisiro mazhinji kushandisa zvimwe mishonga, zvakadai corticosteroids.

Zvose izvi zvinhu zvinogona kukonzera zvibereko chinoratidza ichi, sezvo maplatelet. Ndozvakajairwa neropa varume kazhinji vane zvishoma kupfuura vakadzi nevana. A zvishomanana kuwedzera platelet inobvira pashure ndichibvunza muviri. Iyi haisi zvokurwara. Pashure zororo, nhamba iyi ikadzoka dzose. Thrombocytosis iri nesekondari.

Primary thrombocytosis Zvinokonzera

The chikuru thrombocytosis kunobva kusagadzikana hematopoiesis (inotungamirwa uye kuibvisa masero eropa), mwongo hunde masero. Zvikonzero chingava:

• Mamwe marudzi kupererwa neropa.
• Eritromiya.
• Chirwere myeloid neleukemia.
• Fibrotic degeneration kuti mwongo (myelofibrosis).
• Idiopathic thrombocythemia, kuti platelet count anogona ngazviwedzerwe 4,000.

Secondary thrombocytosis Zvinokonzera

Secondary thrombocytosis kukura somugumisiro pathological ezvinhu (zvirwere) kuti kuchambokanganisa krovetvoritelnyh miviri. The inonyanya kukonzera thrombocytosis yechipiri chiri chirwere.

Possible zvinokonzera thrombocytosis yechipiri:

• Dzinonzi rheumatoid arthritis.
• Rheumatism (zvakarurama zita chirwere ichi - chakasimba rheumatic fivhiri).
• Osteomyelitis kana necrotic kwacho mumwongo.
• Maronda colitis.
• Zvakakomba chiropa zvirwere, zvakadai cirrhosis.
• Tibhii.
• Neoplastic urongwa, semuenzaniso, carcinoma, rwekenza yelymphoma kana Hodgkin chirwere.
• Large kurasikirwa neropa.
• Chenjera hemolysis (kwazvo ezvinhu umo kuora pamusoro erythrocytes kunoitika).

Ko pasi platelet kuverenga?

Thrombocytopenia - chimiro umo maplatelet ropa ipfupi. Ndozvakajairwa mune varume dzimwe zvinyorwa kuwanikwa kusvika bhiriyoni 320 masero por fő, apo vamwe - 400, uye kunzvimbo akasungirwa kuzvidzosera kubvira 180 masero. Kuderedza nhamba iri kakawanda ichakurukurwa thrombocytopenia.

Zvikonzero angava:

• Rwarisa kwendangariro.
• Functional abnormalities pakati mumwongo.
• Pamuviri uye kumwedzi vakadzi.
• Kupererwa neropa akasiyana-siyana.
• Leukemias.
• Nhodzera.
• Zvinokonzerwa inorema simbi.
• Doro akawanda.
• Wandisa kubuda ropa.
• Kutora zvimwe zvinodhaka (zvakadai nemishonga, analgesics, estrogens).

Zvarakasiya kubva kwomuzvarirwo platelet tsika mu kana mirayiridzo zvinoda kunyatsoongorora uye kurapwa zvinodhaka kwete chete, asiwo zvakakodzera zvokudya.
