Platelets ndiyo masero mashoma eropa anokonzerwa nekuvhara mvura yehupenyu. Vanotora chikamu:
- mukumira ropa (hemostasis);
- mukudyisa masvingo emidziyo yeropa.
Ko platelet aggregation process inoitika sei?
Kana tikangotanga kudonhedzwa, muviri unoratidza dambudziko. Thrombocytes dzinomhanyisa kumidziyo yakakanganisika, iyo inotanga kusungirirana pamwechete. Ichi chiito chinonzi aggregation. Zvinotora muzvikamu zviviri:
- Chokutanga, maplatelet anosunganidzwa pamwe chete - iyi ndiyo danho rekutanga rekugadzira maitiro.
- Ipapo vanobatanidzwa pamadziro emidziyo.
Mushure mokunge pavharo remaplatelet zvimwe zvikamu, zvichiri maplatelets anonamatira, uye somugumisiro thrombus inokura kusvikira ichivhara kuputika masvingo emidzi yeropa kuitira kuti ropa risingapfuuri. Zvisinei, kune ngozi inotyisidzira nekuwedzera kwekugadzirisa ropa-maziso - izvi zvinorwisa mwoyo, kupwanya.
Pamusoro pemhando ipi zvayo isina kufanira, tapota taura neyanyanzvi.
Muedzo weRopa wokuvhara
Nekudzidza kweplatelet aggregation zvakakosha kutora kuongororwa ropa:
- Kana paine marwadzo kubva pane zvishoma zvishoma, maronda haaporese zvakanaka, kazhinji kune ropa kubva mumhino - iyi chiratidzo chokuti ropa coagulability inoderedzwa.
- Kana pane kuvhara-pane zvinopesana, coagulability inowedzera.
Kuongororwa kunoitwa kuburikidza nekuisa an aggregation inducer nekucherechedza zvingaitwa. Sezvo inducer, zvinhu zvekemikari zvakagadzirisa zvinhu, izvo zvakanyatsogadzirwa kune zvakasikwa, zvinoshandiswa.
Kusangana kweplatelets kunoongororwa nekubatsira kwevakadaro.
- adrenaline;
- zvikamu zvehutambo hwevascular: adenosine diphosphate (ADP);
- ristocetin (ristomycin);
- collagen;
- serotonin.
Kunongoratidzira aggregation yemaplatelets kunoratidzwa pasina inducers.
Usati watora muedzo, unofanira kunyatsogadzirira kuongorora ropa kuti ive yakarurama. Kuti uite izvi, unofanira kutevera mitemo iyi:
- Usati watora muedzo, rega kutora mishonga yose ye aspirin (dipyridamole, indomethacin uye vamwe) uye zvinodhaka.
- Kuongororwa kunotorwa pamunhu asina chinhu, maawa 12 mushure mekudya kwekupedzisira, kunyanya haifaniri kudya kudya kwemafuta.
- Usazviremera mumuviri, nyarara.
- Kwezuva risingafaniri kunwa kofi, doro, doro, kwete kudya garlic uye kusasvuta.
- Kana mutumbi uri mukuvhiringidza, tsananguro inofanirwa kusarudzwa.
- Zvakakoshawo kuziva kuti panguva yekuenda kumwedzi, kuderera kweropa kuvhara kunoonekwa mumadzimai, uye izvi zvinogona kukanganisa mugumisiro wekuongorora.
Chimiro che platelet aggregation
Chiyero chinowanikwa cheplatelets muropa zvinoreva kuti munhu ane utano hwehutano hwakagadzirwa, maviri uye nhengo zvinopiwa neokisijeni nesimbi mune zvakawanda zvakakwana.
Chimiro chezvakanyorwa zveplatelets zvinobva ku 200 kusvika 400 x 109 / l. Uyewo, muongororo ye laboratori ye stopwatch inoyera nguva iyo zvikamu zvakakura zveplatelet zvinoumbwa. Iyo yakarongeka nguva yekuumbwa ndeyemaminetsi gumi kusvika makumi matanhatu.
Kuwedzera platelet aggregation
Kuti unzwisise rudzi rwemamiriro ezvinhu, apo platelet aggregation inowedzera, iwe unofanirwa kuterera kune izvi: ropa rakaoma, rinofamba zvishoma nezvishoma kuburikidza nemidziyo yeropa, rinopera. Izvi zvinoratidzika semanzwiro ekushaya simba, kuzvimba. Thrombocytosis yakadaro inoitika apo:
- yakawanda atherosclerosis yemidziyo yeropa;
- hypertensive disease;
- chirwere cheshuga mellitus;
- leukemia;
- kenza yemuviri kana kuti itsvo;
- lymphogranulomatosis ;
- mushure mekubviswa kwepleen;
- sepsis.
Dense ropa rinopisa mamiriro ezvinhu asina kunaka akadaro:
- myocardial infarction;
- thrombosis yemakumbo emakumbo;
- kurohwa ;
- kufa kwechimbichimbi kubva kuchiitiko che aorta ne thrombus yakateyiwa, nezvimwewo.
Kuderedza kukanganisa kweplatelets
Neine nhamba shoma yemaplatelet mumidziyo yeropa inenge iine brittle, kubuda ropa kunomira nekuoma.
Kana platelet aggregation yakaderera, unoda:
- Dzivisa kukuvara.
- Ngwarira nemishonga uye doro.
- Kunyatsodya, kubvisa zvokudya zvinonaka uye zvese.
- Pane zvokudya zvakagadzirwa nematare (beet, apulo, buckwheat, nyama, hove, parsley, pepper, nuts, sipinashi).
