Thaum kuaj ntshav, cov qauv leukocyte raug xam. Nws sawv cev rau cov ntsiab lus ntawm ntau chav kawm ntawm cov ntsiab lus raws li feem pua. Ntawm tag nrho cov leukocytes, ib qho kev faib ua feem loj poob rau ntawm segmented neutrophils. Lawv tsim cov khoom ntawm cov ntshav. Leukocytes tau muab faib ua ob pawg loj: agranulocytes thiab granulocytes. Cov tom kawg yog granular. Cov chav kawm ntawm granulocytes, nyob rau hauv lem, muaj xws li basophils, eosinophils thiab neutrophils. Txhua hom cell muaj nws tus kheej granularity thiab nws tus kheej functions.
theem ntawm kev loj hlob ntawm cov ntshav
Cells ntawm chav kawm granulocytic txhua tus mus txog qee theem ntawm kev loj hlob. Hauv thawj theem, myeloblasts raug tsim. Tom qab ntawd, cov hlwb mus dhau ntau theem nruab nrab. Nyob rau hauv tus txheej txheem ntawm kev loj hlob ntxiv, txhua lub ntsiab yog tsim rau hauv ib tug stab neutrophil, thiab ces ib tug segmented neutrophil. Cov menyuam yaus pom muaj nyob hauv cov ntshav tsuas yog thaum muaj kab mob hnyav tshwm sim.
Dab tsi yog qhov txawv ntawm segmented thiab stab neutrophils?
Qhov sib txawv tseem ceeb yog cov duab ntawm lub cell nucleus. Nyob rau hauv lub qub, nws muab faib los ntawm tshwj xeeb constrictions rau hauv 2 los yog 4 ntu. Lub stab neutrophil muaj ib tug du, rod-puab nucleus. Lub cytoplasm ntawm cov hlwb muaj xim liab. Tam sim no nyob rau hauv cov ntsiab lus thiab xim av nplua nplej. Raws li cov kab mob sib kis, nws dhau los ua xiav thiab ua loj dua. Qhov kev tshwm sim no qhia tias muaj cov txheej txheem inflammatory.
Element functions
Stab neutrophil muab kev tiv thaiv kev nkag mus ntawm cov khoom txawv teb chaws, kab mob, fungi, kab mob. Cells kuj muaj kev ua phagocytic. Myeloperoxidase, ib qho enzyme tshwj xeeb, muaj nyob rau hauv granules ntawm stab neutrophil. Nws tsub kom cov kev ua ntawm cov tshuaj tua kab mob. Neutrophils tuaj yeem txav mus rau inflammatory foci.
Leukocyte formula. Tus piv txwv
Qhov concentration uas cov hlwb muaj nyob rau hauv cov ntshav sib raug raws li lub hnub nyoog. Piv txwv li, tus menyuam yaus hnub nyoog qis dua 5 xyoos muaj txog 30% neutrophils. Cov menyuam yaus muaj leukocytes feem ntau hauv cov ntshav. Cov ntsiab lus ntawm neutrophils nyob rau hauv ib tug neeg laus yog li ntawm 1-6%. Kev nce hauv concentration yuav qhia txog kev txhim kho ntawm ntau yam pathologies. Kev nce hauv stab neutrophils hu ua neutrophil. Raws li txoj cai, tus mob no nrog rau kev nce ntxiv hauv cov concentration ntawm leukocytes. Cov kev hloov pauv hauv cov mis no yog ib yam rau lub plawv nres thiab poob siab, ntau yam lom.
Tshwj xeeb, kev ua txhaum cai tau hais tawm hauv cov kab mob myelocytic leukemia. Vim lub fact tiascov stab neutrophil pib predominate, thiab segmented neutrophil, ntawm qhov tsis tooj, ua rau muaj kev pheej hmoo ntawm kev kis kab mob thib ob. Nrog rau qhov txo qis hauv cov ntshav cov ntshav, kev loj hlob ntawm cov kab mob thiab cov kab mob ntev tau pom. Qhov no feem ntau tshwm sim tom qab tau txais cytostatics, kev kho hluav taws xob lossis vim muaj cov kab mob ntshav. Thaum stab neutrophils tsis nyob hauv qhov xav tau, qhov mob no hu ua neutropenia.
