Sezvazvinozivikanwa, ropa revanhu rinosanganisira zvikamu zviviri zvakakosha: plasma uye zvinhu zvakasikwa - erythrocytes, leukocytes, maplatelets. Kuitisa chirwere chekuongorora ropa kunokubvumira kutonga mamiriro ezvehutano hwehuwandu hwemasero eropa uye zvikamu zvayo, kuongorora huwandu hwevanhu hutachiona hwehutano. Kunyanya, chiratidzo pamusoro pezvinetso mumuviri zvinogona kushanda sehuwandu hwakawanda hweplatelet muropa.
Platelet basa uye zvavanoita muropa
Platelets maduku, masineriarizedhe (mashepa eropa), ayo ari zvimedu zve cytoplasm yemamwe bone marrow cells - megakaryocytes. Kuumbwa kweplatelet kunowanikwa mumapfupa emapfupa, mushure mokunge vapinda muropa.
Aya masero eropa anobata basa rinokosha - kupa ropa kuvhara (pamwechete pamwe nemaprotin eropa plasma). Pamusana pemaplatelet, kana masvingo emidziyo yacho yaparara, magetsi anokonzerwa, kuitira kuti mudziyo wakakanganiswa uvharwe newaini yakagadzira (clot). Nokudaro, kubuda ropa kunomira uye muviri unodzivirirwa kubva pakurasika kweropa.
Munguva pfupi yapfuura, zvakasimbiswa kuti maplatelet anowanzobatanidzwa mukugadziriswa kwemashuga akabatwa, achibudisa izvo zvinonzi kukura zvinhu zvinokurudzira kukura kwemasero.
Plateti inorarama mazuva manomwe kusvika kune gumi, nguva dzose inongororwa. Nokudaro, nzira yekugadzira maplatelets ekare uye kugadzirwa kwezvinhu zvitsva inongoramba ichiita mumuviri wemunhu ane hutano. Izvo zvinowanzoitika zveplatelet mu litita revanhu vakura ropa zvinosiyana pakati pe 180 - 320 × 109 masero. Kana kuenzanisa pakati pekuumbwa kwemasero matsva uye kushandiswa kwemarara kunokanganiswa, zvirwere zvinokonzera.
Yakakura maplatelets muropa - zvinokonzera
Nhamba yakawanda yeplatelet muropa inokonzera kuwedzera kweprombosi nekuvhara mitsipa yeropa. Izvi zvinonzi "thrombocytosis" uye yakakamurwa kuva mhando mbiri - yekutanga uye yechipiri.
Primary thrombocytosis inobatanidza nekushaya simba kwemafupa emasokera, zvichiita kuti kuwedzerwa kunoshamisa kwenhamba yeplatelets eropa muropa. Kuongorora kukuru kweropa kunogona kuratidza kuti maplatelet anosimudzwa kusvika 800 - 1200 × 109 masero / l uye nezvimwe. Sezvo mutemo, chekutanga thrombocytosis inoratidzwa kuti yakanganisa, nokuti kakawanda, hutachiona hahuna pachena zviratidzo zvemakiriniki. Mune zvimwe zviitiko zviratidzo zvinotevera zvinogona kuonekwa:
- headaches;
- subcutaneous hemorrhage;
- kubuda ropa (nasal, uterine, nezvimwewo);
- cyanotic ganda tone, nezvimwewo.
Yakawedzerwa platelet mairi muropa neyechipiri thrombocytosis inogona kukonzerwa nehuviri hwehutano uye hutachiona. Sezvo mutemo, pamwe nechirwere chechipiri, nhamba yeplatelets haisi kupfuura 1000 × 109 masero / litita.
Zvikonzero zvepanyama zvekuwedzera kwema platelet muropa zvinogona kuva:
- physical overstrain;
- kuwedzera adrenaline muropa;
- pamuviri.
Zvimwe zvinokonzerwa nehutachiona zvinokonzera kuwedzera kweplatelet kuwanda muropa ndizvo zvinowanzowedzera zvinotevera:
- Zvirwere zvinotapukira uye zvinovhiringidza zvinokonzerwa nemavirusi, mabhakitiriya, fungi, parasites (hepatitis, pneumonia, meningitis, thrush, encephalitis, etc.).
- Internal bleeding.
- Kupindira kwekupindira uye kushungurudzwa kwomuviri.
- Sarcoidosis chirwere chekuvhiringidzika chemuitiro umo dzimwe nhengo uye zvirongwa (kazhinji mapapu) zvinokanganiswa nekuumbwa kwegranules (nodules) mavari.
- Kubviswa kwepleen - nhengo iyo inotora chikamu mukutora maplatelets ekare, uye iyo inochengetedza anenge 30% emaplatelets eropa.
- Kukuvadza kunokonzera mhuka mupascreatitis kana tissue necrosis.
- Kusakwana kwesimbi mumuviri.
- Zvirwere zvepachikafu.
- Kubvuma mamwe mishonga.
