Neutrophils yog ib pab pawg ntawm leukocytes uas koom nrog hauv kev tsim cov kab mob tua kab mob thiab tshuaj tiv thaiv kab mob, hauv lwm lo lus, tsim kev thaiv kev nkag mus ntawm cov kab mob tsis zoo no rau hauv lub cev. Lawv cov dej num hauv kev tawm tsam cov kab mob no tsawg dua, tab sis cov neutrophils suav nrog cov mis leukocyte thiab yuav tsum suav.
Hais txog qhov ntau, qhov tshwj xeeb ntawm leukocyte no yog qhov tseem ceeb, thiab lawv tau tsim nyob rau hauv qaum qaum qaum. Lawv txoj kev sib xyaw ua ke muab cov haujlwm tiv thaiv zoo heev uas yog cov yam ntxwv ntawm txhua hom leukocytes. Thaum ib qho kev hloov pauv ntawm lawv cov ntsiab lus hauv ib qho kev taw qhia lossis lwm qhov tau sau tseg hauv kev kuaj ntshav, nws yog ib txwm hais tias ib yam dab tsi tshwm sim hauv lub cev. Qhov siab neutrophils qhia tias muaj cov txheej txheem inflammatory lossis kab mob sib kis. Yog tias lawv cov ntsiab lus raug txo, qhov no qhia tias muaj cov kab mob los yog kab mob cab hauv lub cev. Txawm li cas los xij, qhov tshwm sim no tuaj yeem cuam tshuam nrog kev noj qee yam tshuaj, yog li yog tias koj siv cov tshuaj rauKev kho mob ntawm cov txheej txheem mob ntev lossis mob hnyav, qhov no yuav tsum tau qhia rau tus kws kho mob soj ntsuam cov txiaj ntsig ntawm koj qhov kev sim.
Thaum muaj kab mob los yog o tshwm sim hauv lub cev, cov hlwb leukocyte tsis paub tab raug tso tawm, yog li cov neutrophils nce siab hauv kev kuaj ntshav. Lawv lub luag haujlwm tseem ceeb yog txhawm rau nkag mus rau hauv thaj chaw ntawm cov kabmob thiab cov ntaub so ntswg, tom qab ntawd muaj kev tshawb pom zoo ntawm cov kab mob hauv lub cev uas ua rau muaj cov tshuaj tiv thaiv zoo sib xws ntawm lub cev. Tom qab ntawd cov txheej txheem ntawm phagocytosis pib, uas tau tshwm sim hauv kev tsim cov kab mob purulent. Qhov tseeb, cov no yog cov neutrophils uas tau lwj hauv kev tawm tsam cov kab mob, thiab hauv lub cev lawv cov lej nce zuj zus, raws li tau sau tseg hauv cov txiaj ntsig ntawm kev kuaj ntshav.
Neutrophils tuaj yeem stab (raws li lawv cov hom tsis paub tab hu ua) thiab segmented (lawv hom mature). Cov ntsiab lus ntawm yav dhau los yog suav tias yog ib txwm nyob rau hauv thaj tsam ntawm ib mus rau rau feem pua, thaum tom kawg tuaj yeem yog los ntawm 47 mus rau 72%. Neutrophils nyob rau hauv cov ntshav yog nce siab nyob rau hauv cov kab mob hauv qab no: otitis media, pneumonia, appendicitis, peritonitis, sepsis, sinusitis thiab lwm yam pathologies nrog rau cov txheej txheem purulent. Raws li txoj cai, qhov mob hnyav ntawm cov kab mob no yog nrog los ntawm kev nce hauv kev tso tawm ntawm cov kab mob ntawm cov ntshav no. Qhov siab neutrophils tsis tshua qhia txog cov kab mob ntev los yog lawv hom kab mob. Tsis tas li ntawd, tsis txhob hnov qab txog cov nyhuv ntawm qee yam tshuaj ntawm cov ntshav muaj pes tsawg leeg.
Txawm li cas los xij, nce neutrophils tsis tas ua nws tus kheej, cuam tshuam rau lwm yam ntawm cov mis leukocyte. Piv txwv li, yog tias qib ntawm lymphocytes nce, qhov no qhia tau hais tias muaj kab mob kis, yog li ntawd, neutrophils hauv qhov xwm txheej zoo li no yuav raug txo. Qhov no yog ib txwm teb ntawm lub cev rau cov teebmeem ntawm tus kab mob. Nws yog qhov tsawg heev rau lymphocytes thiab neutrophils yuav tsum tau nce nyob rau tib lub sijhawm, txawm hais tias tib neeg lub cev yog qhov tsis txaus ntseeg loj, thiab qee zaum cov txheej txheem tseem ceeb tshaj plaws tuaj yeem tshwm sim hauv nws.
