Kev qaug ntshav ntawm platelets thaum cev xeeb tub yog ib qho tseem ceeb tshaj qhia, txo qhov uas tuaj yeem pab ua rau ntshav. Aggregation hauv cov tshuaj yog hais txog rab peev xwm platelets mus koom, i.e., plhom ntshav plhom.
Cov txheej txheem no yog raws li nram no. Yog hais tias cov phab ntsa ntawm cov hlab ntsha puas ntsoog, cov ntshav pib ntws los ntawm lawv kom tsis txhob muaj lub txim, lub cev xa ib lub tswb mus rau lub hlwb. Yog li, tom qhov chaw ntawm kev puas tsuaj, platelets tshwm thiab, gluing ua ke, kaw qhov khoob ntawm lub nkoj.
Los txiav txim siab rau qhov ntsuas no, ib coagulogram yog ntsuas tawm-kuaj ntshav siv ib hom kev sim uas siv inducers-tshwj xeeb tshuaj uas ua rau muaj aggregation. Cov paib ntawm aggregation ntawm platelets thaum cev xeeb tub thaum nrog cov khoom ntawm cov tshuaj no yog 30-60%.
Hypoaggregation ntawm platelets thaum cev xeeb tub
Txo cov platelet aggregation thaum lub caij cev xeeb tub yuav tshwm sim vim muaj kev puas tsuaj ntxiv los yog kev siv cov ntshav platelets. Qhov ua rau ua li no tuaj yeem ua rau ntshav tsis so, ua txhaum ntawm lub cev tsis muaj zog, lossis noj tsis haum ntawm poj niam cev xeeb tub. Hypoaggregation platelets thaum lub caij cev xeeb tub yog cov tsos mob xws li nqaij tawv thiab los ntshav. Nyob rau hauv xws li no, cov ntshav plates yog tsim los ntawm ntau me me, los yog tau txais ib qho qauv tsis sib haum. Hauv kev yug me nyuam tus cwj pwm xws li ntshav ntawm coagulability tuaj yeem ua rau ntshav loj heev.
Hyperaggregation ntawm platelets thaum cev xeeb tub
Ib qho kev nce me ntsis yog qhov txheej txheem ntuj tsim nyob rau lub sij hawm ntawm gestation - qhov no yog txuam nrog kev hloov ntawm utero-placental. Hyperaggregation ntawm platelets thaum cev xeeb tub tuaj yeem ua rau muaj cov kab mob thrombosis. Thrombosis, mob ntsws los yog venous, tej zaum yuav muaj tus mob antiphospholipid syndrome, uas feem ntau yog qhov ua rau kev qaug zog thaum ntxov.
