Thaum kawg thiab fibrin net yaj, tawg ntawm cov protein raug tso tawm rau hauv lub cev. Cov tawg no yog degradation ntawm fibrin cov khoom lossis FDPs. Yog tias koj lub cev tsis tuaj yeem ua kom cov ntshav txhaws, koj tuaj yeem muaj qhov txawv txav ntawm FDPs. Cov theem ntawm FDPs no nce ntxiv tom qab ib qho kev tshwm sim thrombotic.
Hauv qhov no, uas tuaj yeem txo qis fibrin clot?
Cov tawg fibrin cov fragments hu ua degradation ntawm fibrin cov khoom (FDPs). Hlauv yog degraded los ntawm plasmin. Plasmin converts fibrinogen cov pib mus rau X tivthaiv, uas tau muab cais ua ntu Y thiab tivthaiv D.
Tsis tas li ntawd, FDP yog dab tsi thiab nws qhov tseem ceeb? Fibrin degradation khoom ( FDP ) yog cov tshuaj uas nyob twj ywm nyob rau hauv koj cov ntshav tom qab koj lub cev yaj cov ntshav txhaws. Koj cov fibrinolytic (khov-tsoo) txheej txheem tswj hwm thiab tswj cov ntshav tawg. Cov tsim ntawm cov plug los yog clot hu ua cov clotting cascade. Fibrin yog cov protein uas pab tau nyob rau hauv ua ntshav.
Ua qhov no hauv kev txiav txim siab, dab tsi yog fibrin yaj los ntawm?
T. P. UA yog ib qho txuas hauv cov kab mob sib txuas hauv cov hlab ntsha. Nws tau tsim tawm ib txwm los hloov lwm cov protein ntshav, hu ua plasminogen, rau hauv cov enzyme hu ua plasmin. Qhov no, nyeg, yaj fibrin , cov khoom siv uas tuav khov ua ke.
D dimers thiab fibrin degradation cov khoom zoo li cas?
Nqe lus piav qhia: FDP, FSP, Fibrin Split Cov Khoom . Fibrin / fibrinogen degradation khoom (FDP) yog qhov tshwm sim ntawm kev tawg ntawm fibrinogen cov (thawj fibrinogenolysis) thiab fibrin (fibrinolysis). Nyob rau hauv sib piv, lub D - Dimer pom kev tawg khoom uas tsuas yog tsim los ntawm kev ua ntawm plasmin ntawm kev ruaj khov fibrin cov.

Cov mob me me lossis qib nruab nrab tuaj yeem kho nrog kev txhaj tshuaj antihistamine thiab/lossis kev txhaj tshuaj cortisone qhov hnyav dua tuaj yeem xav tau epinephrine thiab txhoj puab heev tso dej tawm thiab txhawb nqa
Dab tsi yog lub hauv paus ntawm lub cev rau amenorrhoea tom qab xeeb menyuam thiab lwm yam dab tsi uas tuaj yeem ua rau amenorrhoea?
Amenorrhea cov lus tseeb Genetic los yog yug hauv tsev yog qhov ua rau pom thawj zaug ntawm tus mob amenorrhea. Amenorrhea tuaj yeem tshwm sim los ntawm kev ua haujlwm tsis zoo ntawm zes qe menyuam, pituitary caj pas, hypothalamus, lossis lub tsev menyuam. Kev qoj ib ce hnyav, hnyav hnyav, mob lub cev, thiab kev nyuab siab tuaj yeem ua rau muaj kev tsis txaus ntseeg
Dab tsi yog qhov txiaj ntsig ib txwm rau PaO 2 Dab tsi yog qhov txiaj ntsig rau kev txiav txim siab qhov hnyav ntawm hypoxemia?
Zoo li feem ntau qhov kev kho mob ib txwm muaj txiaj ntsig thiab ntau yam, lub ntsiab lus tuaj yeem sib txawv me ntsis, tab sis feem ntau cov ntsiab lus hauv qab no siv: Ua rau me me hypoxemia: PaO2 = 60 txog 79 mmHg. Qhov nruab nrab hypoxemia: PaO2 = 40 txog 59 mmHg. Hypoxemia hnyav: PaO2 <40 mmHg
Dab tsi yog qhov khoom degradation ntawm heme?
Bilirubin yog kab tawm tetrapyrrole uas tau tsim thaum lub sijhawm txheej txheem ntawm heme degradation. Heme raug tso tawm los ntawm kab mob hemeproteins, suav nrog hemoglobin thiab cytochrome P450, thiab metabolized los ntawm heme oxygenase los tsim cov pa roj carbon monoxide, biliverdin, thiab hlau dawb
Dab tsi ua rau tub ceev xwm saib xyuas tshuaj rau dab tsi?
Qhov feem ntau raug zam txim thiab raug tshuaj ntsuam xyuas thiab ntsuas cawv yog: 5-panel panel drugurine test, uas txheeb xyuas cov zis zis rau cov yeeb tshuaj xas, cocaine, PCP, amphetamines, thiab opiates. Ntau qhov kev sim tshuaj ntsuam xyuas kev sim tshuaj kuj tseem ntxiv cawv rau 5-paneltest
