Platelets yog cov qe ntshav tsawg tshaj plaws rau cov qaug dej qaug. Lawv koom ua ke:
- nyob rau hauv kev siv tshuaj tiv thaiv los ntshav (hemostasis);
- nyob rau hauv pub cov phab ntsa ntawm cov hlab ntsha.
Platelet aggregation txheej txheem li cas?
Thaum peb tau txais qhov me ntsis ntuag, lub cev pib teeb meem. Thrombocytes nrawm rau cov hlab ntsha puas, uas pib kua nplaum ua ke. Qhov kev ua no hu ua aggregation. Nws yuav siv qhov chaw hauv ob theem:
- Ua ntej, cov platelets yog glued ua ke - qhov no yog thawj theem ntawm thrombus tsim.
- Tom qab ntawd lawv tau txuas rau phab ntsa ntawm cov hlab ntsha.
Tom qab ntawd nyob rau ntawm cov ntshav khov ua lwm cov platelets, tseem platelets adhere, thiab vim li ntawd cov thrombus hlob mus txog rau thaum nws thaiv cov phab ntsa ruptured ntawm cov hlab ntsha kom ntshav tsis ntws tawm. Txawm li cas los xij, muaj kev txaus ntshai uas tsim kev kub ntxhov nrog cov kab mob hauv cov ntshav zuaj - cov no yog lub plawv nres, cwj nrag.
Rau tej yam txawv txav, thov hu rau tus kws kho mob tshwj xeeb.
Kev ntsuam xyuas ntshav rau cov ntshav
Rau txoj kev kawm ntawm platelet aggregation nws yog ib qhov tsim nyog los coj kev kuaj ntshav:
- Yog hais tias muaj nqaij hlav ntawm lub slightest blows, qhov txhab tsis kho zoo, feem ntau muaj ntshav los ntawm lub qhov ntswg - qhov no yog ib lub teeb liab tias cov ntshav coagulability yog qis.
- Yog hais tias muaj o tuaj - ntawm qhov tsis sib xws, coagulability nce.
Qhov kev tsom xam yog ua tiav los ntawm kev qhia ib qho aggregation inducer thiab saib cov tshuaj tiv thaiv. Raws li ib qho kev tshwm sim, cov tshuaj khov-tsim cov tshuaj, uas yog nyob ze rau hauv qhov sib xyaw kom ntuj, siv.
Qee lub plhom ntawm platelets nrog kev pab los ntawm cov kev qhia xws li:
- adrenaline;
- Cheebtsam ntawm phab ntsa cov leeg: adenosine diphosphate (ADP);
- ristocetin (ristomycin);
- collagen;
- serotonin.
Tshaj ua ke ntawm platelets yog txiav txim tsis muaj inducers.
Ua ntej koj yuav kuaj, koj yuav tsum ua tib zoo npaj rau kev kuaj ntshav kom yog. Ua li no, koj yuav tsum ua raws li cov cai no:
- Ua ntej noj cov tshuaj no, tsum tsis txhob noj cov tshuaj aspirin (dipyridamole, indomethacin thiab lwm tus) thiab tshuaj tua kabmob (antidepressants).
- Txoj kev ntsuam xyuas no yog siv rau ntawm lub plab, 12 teev tom qab noj mov tas, tshwj xeeb tshaj yog nws tsis tsim nyog noj zaub mov rog.
- Tsis txhob cia koj tus kheej lub cev, ua siab tus.
- Rau ib hnub kom tsis txhob haus kasfes, dej cawv, tsis txhob noj qej thiab tsis haus luam yeeb.
- Yog hais tias lub cev nyob rau hauv ib qho kev ua rau muaj kev ywj pheej, kev tshawb xyuas yuav tsum muab ncua.
- Nws tseem ceeb heev uas yuav tsum paub tias thaum lub caij ua pojniam, kev txo qis ntshav khov hauv cov poj niam, thiab qhov no tuaj yeem cuam tshuam txog qhov tshwm sim ntawm kev ntsuam xyuas.
Cov cai ntawm platelet aggregation
Ib qho ntshav qab zib hauv cov ntshav txhais tau hais tias tus neeg muaj ntshav qab, cov ntaub so ntswg thiab lub nruab nrog cev muaj oxygen thiab hlau ua kom txaus.
Tus qauv rau cov ntsiab lus ntawm platelets ranges ntawm 200 mus rau 400 x 109 / l. Tsis tas li ntawd, nyob rau hauv kev kuaj kev kuaj ntawm kev ntsuas kev ntsuas kev ntsuas lub sij hawm rau cov khoom uas muaj cov platelets loj loj. Lub sijhawm ua tiav yog 10 mus rau 60 feeb.
Ua rau platelet aggregation
Yuav kom nkag siab tias yam mob zoo li cas, thaum platelet aggregation nce, koj yuav tsum tau ua tib zoo saib xyuas qhov no: cov ntshav ntom, qeeb qis los ntawm cov hlab ntsha, ua pa taw. Qhov no tshwm sim nws tus kheej ua zoo nkaus li tus neeg tsis taus, o. Xws li tus kab mob thrombocytosis thaum:
- txhua yam kabmob hauv plhaw ntawm cov hlab ntsha;
- hypertensive kab mob;
- ntshav qab zib mellitus;
- leukemia;
- mob plab lossis lub raum;
- lymphogranulomatosis ;
- tom qab tshem tawm ntawm tus po;
- sepsis.
Ntshav ntshav ua rau yus tsis zoo xws li:
- myocardial infarction;
- thrombosis ntawm cov leeg ntawm cov ceg;
- mob stroke ;
- Sudden tuag los ntawm occlusion ntawm aorta los ntawm ib tug severed thrombus, thiab lwm yam.
Txo cov aggregation ntawm platelets
Nrog rau cov neeg platelets tsawg hauv cov hlab ntsha ua rau me me, los ntshav tsis nrog kev nyuaj.
Yog tias platelet aggregation txo, koj yuav tsum:
- Tsis txhob raug mob.
- Ceev faj nrog cov tshuaj thiab cawv.
- Ua noj ua haus, tshem tawm ntsim thiab cov khoom noj khoom qab ntsev.
- Muaj cov zaub mov muaj hlau (beets, apples, buckwheat, nqaij, ntses, zaub txhwb qaib, kua txob, ceev, zaub ntsuab).
