Qhov sib txawv tseem ceeb ntawm hemolysis thiab crenation yog qhov hemolysis yog qhov tshwm sim uas tshwm sim thaum cov qe ntshav liab nyob rau hauv cov tshuaj hypotonic, ua rau cov qe ntshav liab o tuaj thiab tawg vim muaj dej ntau rau hauv cov hlwb., thaum crenation yog ib qho tshwm sim uas tshwm sim thaum cov qe ntshav liab nyob rau hauv cov tshuaj hypertonic, ua rau cov qe ntshav liab shrivel vim yog cov dej ntws tawm ntawm cov hlwb ntau dua.
Hemolysis thiab crenation yog ob qhov tshwm sim uas tshwm sim hauv cov qe ntshav liab vim osmosis. Osmosis yog ib qho kev txav ntawm cov kuab tshuaj los yog dej molecules los ntawm ib qho kev xaiv permeable membrane los ntawm ib cheeb tsam ntawm cov dej muaj peev xwm mus rau thaj tsam ntawm cov dej tsawg. Cov txheej txheem no sib npaug ntawm cov ntsiab lus ntawm ob sab.
Hemolysis yog dab tsi?
Hemolysis yog ib qho tshwm sim uas tshwm sim thaum cov qe ntshav liab nyob hauv cov tshuaj hypotonic. Nws ua rau cov qe ntshav liab o tuaj thiab tawg vim cov dej ntau ntxiv hauv cov hlwb. Hauv tib neeg lub cev, hemolysis yog txheej txheem ntawm lub cev uas tshwm sim hauv cov qe ntshav liab thaum lawv laus dhau lawm. Lub cev feem ntau ua rau hemolysis hauv tus po. Raws li cov ntshav tau lim los ntawm lub cev no, cov qe ntshav liab qub thiab puas lawm raug puas tsuaj los ntawm cov qe ntshav dawb thiab macrophages.
Daim duab 01: Hemolysis
Txawm li cas los xij, qee qhov cuam tshuam sab hauv thiab sab nrauv tuaj yeem ua rau hemolysis unnaturally. Cov hauv paus ntsiab lus no muaj xws li keeb kwm, kab mob ntawm cov cell membrane, tau txais cov kab mob cell membrane, cov xwm txheej cuam tshuam rau RBC metabolism, hemoglobinopathies, thiab txawv txav hauv RBC membrane. Ntawm qhov tod tes, cov extrinsic yam muaj xws li tshuaj, kab mob, tshuaj xws li penicillin, acetaminophen, txhua yam mob uas ua rau muaj zog spleen kev ua si, tiv thaiv kab mob, mob siab rau lub cev ua si, mechanical puas tsuaj los ntawm lub plawv li qub, co toxins xws li txhuas thiab tooj liab, thiab tshuaj lom nrog rau cov venom. Tsis tas li ntawd, hemolysis ntau dhau tuaj yeem ua rau hemolytic anemia, uas yog qhov teeb meem tseem ceeb. Qhov xwm txheej no tuaj yeem kho tau los ntawm kev muab ntshav lossis lwm yam kev kho mob.
Crenation yog dab tsi?
Crenation yog qhov tshwm sim uas tshwm sim thaum cov qe ntshav liab nyob hauv cov tshuaj hypertonic. Nws ua rau cov qe ntshav liab shrivel vim dej txav tawm ntawm cov hlwb. Cov qe ntshav liab yog qhov ua rau muaj kev tsim txom vim yog cov lus teb rau cov kev hloov ionic hauv cov ntshav lossis kev txawv txav hauv cov cell membrane. Cov kev hloov pauv no tuaj yeem cuam tshuam lub cell lub peev xwm los tswj lub xeev isotonic.
Daim duab 02: Crenation
Feem ntau, muaj ob hom ntshav liab crenated: echinocytes thiab acanthocytes. Ob hom cell no muaj cov duab txawv txawv. Lawv tshwm nyob rau hauv ib daim ntawv rounder thiab muaj spiny projections ntawm lub xov tooj ntawm tes. Hauv echinocytes, cov txha nraub qaum yog luv, sib xws, thiab tsis tu ncua spaced. Hom crenation no feem ntau yog thim rov qab. Acanthocytes muaj cov nqaj qaum ntawm cov cell membrane uas tshwm sim nyob rau hauv qhov sib txawv thiab txawv txav, tus lej, thiab ntev. Tsis tas li ntawd, hom crenation no yog irreversible.
Dab tsi zoo sib xws ntawm Hemolysis thiab Crenation?
- Hemolysis thiab crenation yog ob qhov tshwm sim uas tshwm sim hauv cov qe ntshav liab vim osmosis.
- Nyob rau hauv ob txoj kev, muaj kev txav ntawm cov kuab tshuaj hla ib daim nyias nyias.
- Cov qe ntshav liab 'natural qauv (zoo li thiab loj) hloov nyob rau hauv ob qho tib si txheej txheem.
- Ob txheej txheem tuaj yeem tshwm sim hauv tib neeg lub cev ib txwm muaj lossis vim muaj ntau yam mob.
Qhov txawv ntawm Hemolysis thiab Crenation yog dab tsi?
Hemolysis yog ib qho tshwm sim tshwm sim thaum cov qe ntshav liab nyob rau hauv cov tshuaj hypotonic, uas ua rau cov qe ntshav liab o thiab tawg, thaum crenation yog ib qho tshwm sim tshwm sim thaum cov qe ntshav liab nyob rau hauv cov tshuaj hypertonic, uas ua rau liab. ntshav mus tshum. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm hemolysis thiab crenation. Tsis tas li ntawd, nyob rau hauv hemolysis, cov qe ntshav liab loj zuj zus, whereas, hauv crenation, cov qe ntshav liab loj zuj zus.
Cov hauv qab no qhia txog qhov sib txawv ntawm hemolysis thiab crenation hauv daim ntawv teev npe rau kev sib piv ntawm ib sab.
Summary – Hemolysis vs Crenation
Hemolysis thiab crenation yog ob qhov tshwm sim uas tshwm sim hauv cov qe ntshav liab vim osmosis. Hemolysis tshwm sim thaum cov qe ntshav liab nyob hauv cov tshuaj hypotonic, ua rau cov qe ntshav liab o thiab tawg vim dej rau hauv cov hlwb. Crenation tshwm sim thaum cov qe ntshav liab nyob rau hauv cov tshuaj hypertonic, ua rau cov qe ntshav liab shrivel vim dej txav tawm ntawm cov hlwb. Yog li, qhov no qhia txog qhov sib txawv ntawm hemolysis thiab crenation.
