Qhov Tseem Ceeb - Hemostasis vs Coagulation
Vascular system lossis circulatory system yog lub kaw lus kaw uas tso cai rau cov ntshav, as-ham, gasses, cov tshuaj hormones thiab lwm yam tseem ceeb hauv lub cev los ntawm kev sib txuas ntawm cov hlab ntsha. Tshwj tsis yog tias muaj kev raug mob lossis kev raug mob tshwm sim, cov ntshav yuav tsis tawm los ntawm cov hlab ntsha. Thaum muaj kev puas tsuaj rau cov hlab ntsha, nws raug kho tam sim ntawd kom tsis txhob muaj ntshav. Hemostasis yog ib qho txheej txheem ntuj tsim los ua kom tsis txhob los ntshav los ntawm qhov chaw raug mob. Nws tshwm sim ntawm peb txoj kev. Ntshav txhaws lossis ntshav coagulation yog cov kauj ruam kawg ntawm hemostasis. Lub qhov ntawm lub vascular system yog thaiv los ntawm ib tug blot clot tsim los ntawm platelets thiab coagulating yam. Qhov sib txawv tseem ceeb ntawm hemostasis thiab coagulation yog tias hemostasis yog tag nrho cov txheej txheem uas tso tseg los ntshav vim kev raug mob thaum coagulation yog cov kauj ruam kawg ntawm hemostasis uas tsim cov ntshav txhaws los thaiv lub qhov ntawm cov hlab ntsha.
YHemostasis yog dab tsi?
Hemostasis yog txheej txheem ntuj tsim los tiv thaiv los ntshav ntau dhau tom qab raug mob. Nws yog cov txheej txheem ntawm ntuj ntshav txhaws, uas ua raws li thawj theem ntawm kev kho qhov txhab. Muaj ntau ntau yam kev koom tes hauv hemostasis. Lawv yog vasoconstriction, cov ntaub so ntswg o, platelet aggregation thiab ntshav coagulation. Raws li qhov tshwm sim ntawm vascular, platelet thiab plasma yam, cov ntshav raug ntes hauv cov hlab ntsha raug mob los ntawm cov txheej txheem hemostasis. Cov kab mob hemostatic tswj cov ntshav hauv cov kua hauv lub cev hauv lub cev thiab tseem tsim cov ntshav txhaws lossis fibrin clots thaum muaj mob hlab ntsha.
Platelets ua haujlwm tseem ceeb hauv hemostasis. Lawv yog qhov tseem ceeb rau kev tsim cov ntshav txhaws thiab ua kom cov coagulation proteins. Kev mob ntawm hemostasis ua rau cov ntshav ntau dhau tom qab raug mob. Platelet disorders yog qhov tseem ceeb ntawm lawv. Platelet ntau lawm tuaj yeem txo qis lossis platelet puas tuaj yeem nce ntxiv thaum muaj platelet tsis meej; platelets ua haujlwm kuj tuaj yeem ua tsis taus. Cov xwm txheej no cuam tshuam rau hemostasis thiab ua rau muaj qhov txawv txav hauv hemostasis.

Coagulation yog dab tsi?
ntshav coagulation yog ib qho txheej txheem tseem ceeb. Thaum cov hlab ntsha raug mob lossis raug txiav, cov ntshav poob ntau yuav tsum tau tiv thaiv ua ntej nws ua rau poob siab lossis tuag. Nws yog ua los ntawm kev hloov cov ntsiab lus tshwj xeeb hauv cov ntshav mus rau hauv insoluble gel-zoo li tshuaj ntawm qhov chaw raug mob. Qhov no yog hu ua ntshav txhaws lossis ntshav coagulation. Vim yog txoj kev no, cov ntshav tsis tu ncua los ntawm cov hlab ntsha raug mob, cov ntaub so ntswg thiab cov khoom nruab nrog cev raug tso tseg, thiab cov teeb meem tuaj yeem raug tiv thaiv sai li sai tau. Ntshav coagulation yog ua tiav los ntawm kev ua cov ntshav txhaws. Cov ntshav txhaws muaj ib lub ntsaws ntawm platelets thiab lub network ntawm insoluble fibrin molecules.
ntshav coagulation yog ua los ntawm kev tsim cov fibrin clot. Fibrin yog ib qho insoluble, fibrous thiab non-globular protein koom nrog hauv cov ntshav txhaws. Nws yog lub hauv paus ntaub polymer ntawm cov ntshav txhaws. Fibrin tsim tshwm sim raws li cov lus teb rau kev raug mob nyob rau hauv ib feem ntawm lub vascular system los yog lub circulatory system. Thaum muaj kev raug mob, ib qho protease enzyme hu ua thrombin ua rau fibrinogen thiab ua rau nws polymerize rau hauv fibrin, uas yog ib qho insoluble gel zoo li protein. Tom qab ntawd fibrin, ua ke nrog cov platelets, tsim cov ntshav txhaws ntawm qhov chaw mob kom tsis txhob los ntshav tas mus li.
Daim duab 02: Ntshav Coagulation
Kev tsim ntawm fibrin yog tag nrho nyob ntawm thrombin tsim los ntawm prothrombin. Lub fibrinopeptide, pom nyob rau hauv nruab nrab cheeb tsam ntawm lub fibrinogen, yog cleaved los ntawm thrombin hloov soluble fibrinogen rau insoluble fibrin polymer. Muaj ob txoj hauv kev hauv kev tsim fibrin: extrinsic pathway thiab intrinsic pathway. Kev tsis txaus ntawm ob txoj hauv kev no tuaj yeem ua rau cov ntshav txhaws tsis zoo uas thaum kawg ua rau hemorrhage. Yog li, ob qho tib si sab hauv thiab sab nraud txoj hauv kev ntawm cov ntshav txhaws yog qhov tseem ceeb rau hemostasis.

| Hemostasis tuaj yeem faib ua ob hom npe hu ua thawj hemostasis thiab theem nrab hemostasis. | Coagulation tuaj yeem categorized rau hauv txoj hauv kev ntawm cov ntshav txhaws thiab extrinsic txoj kev ntawm cov ntshav txhaws. |
| Hemostasis tuaj yeem pom qhov txawv txav vim platelet mob. | Coagulation tuaj yeem cuam tshuam los ntawm kev mob ntawm daim siab thiab tsis ua haujlwm lossis tsis ua haujlwm fibrinogen ntau lawm. |
Summary – Hemostasis vs Coagulation
Hemostasis yog cov txheej txheem physiological uas tso tseg los ntshav ntawm qhov chaw ntawm qhov raug mob thaum tswj cov ntshav ntws mus rau lwm qhov hauv kev ncig. Nws tshwm sim ntawm ob peb kauj ruam. Ntshav coagulation yog qhov kawg tshwm sim ntawm hemostasis. Qhov no yog qhov sib txawv tseem ceeb ntawm hemostasis thiab coagulation. Ntshav txhaws yog ib txoj hauv kev tseem ceeb los tiv thaiv cov ntshav ntau dhau ntawm qhov raug mob. Fibrin thiab fibrinogen yog ob lub plasma proteins koom nrog hauv cov ntshav txhaws ua ke nrog platelets.
