Segmented qe - peb defenders

Nyob rau hauv kev, tsom xam ntawm cov ntshav yuav tsum tau xam WBC, i.e. qhov feem pua ntawm cov ntau yam cov chav kawm ntawm leukocytes nyob rau hauv cov ntshav. Feem ntau ntawm cov leukocytes nyob rau hauv cov neeg laus nyob rau hauv cov mis mos comprise segmented qe (kwv yees li 70%). Lawv yog cov - lawv yog cov tseem ceeb ib feem.

Dawb ntshav raug muab faib ua ob yam loj series: granulocytes (granular) thiab agranulocytes (uas tsis muaj grain). Granulocytes, nyob rau hauv lem, yog subdivided rau hauv qe, eosinophils thiab basophils. Txhua yam ntawm cell muaj ib tug meej grain nyob rau hauv lub cytoplasm thiab yog nws tus kheej nta tshwj xeeb.

Tag nrho cov hlwb ntawm granulocytic series nyob rau hauv nws txoj kev loj hlob los ntawm cov theem ntawm kev loj hlob ntawm myeloblasts, los ntawm ib tug series ntawm intermediate tsis paub qab hau hlwb nkaug thiab segmented leukocytes. Qhov no siv rau tag nrho peb hom granulocytes - mus qe, eosinophils thiab basophils. Nyob rau hauv peripheral ntshav feem ntau pom xwb qe nkaug thiab segmented. Tus yau hlwb nyob rau hauv cov ntshav los ntawm pob txha tsim muaj xwb nyob rau hauv mob loj heev cov kab mob.

Nkaug neutrophiles txawv cov duab ntawm lub cell nucleus. Tus thawj tseem ceeb yog tiaj tus, zoo li tus nkhaus wand. Qhov thib ob cov tub ntxhais yog muab faib ua ob peb tshwj xeeb constrictions (2-4) feem. Lub cytoplasm ntawm hlwb pleev xim rau liab. Nws muaj ib tug zoo grain xim av. Nyob rau hauv kis kab mob qe graininess ua loj, thiab xiav (hu ua toxigenic granularity). Qhov no yog ib tug ntawm txuam rau o.

Muaj nuj nqi, uas yog ua nkaug neutrophiles nyob rau hauv lub cev yog kev tiv thaiv los ntawm txawv teb chaws li hais, cov kab mob, fungi thiab cov kab mob. Granulocytes muaj ib tug phagocytic kev ua si. Cov granules muaj kev enzyme myeloperoxidase, nws tej cov nyhuv ntawm antibacterial tshuaj. Neutrophils yuav nquag tsiv mus nyob rau lub homphiaj ntawm o.

Tus nqi segmented qe thiab lwm lub hlwb nyob rau hauv lub leukocyte mis sau raws nkaus Ii hnub nyoog kev cai. Yog li, nyob rau hauv cov me nyuam nyob rau hauv 5 lub xyoos yog yeej los ntawm lymphocytes thiab qe tsis muaj ntau tshaj li 30%. Cov nab npawb ntawm cov qhab qe nyob rau hauv ib txwm nqi rau 1-6%. Qhov nce nyob rau hauv lub xov tooj qe yog nrog los ntawm ntau yam kab mob thiab yog hu ua neutrophilia.

Feem ntau neutrophilia nrog tag nrho nce leukocyte. Nws yog feem ntau qe nkaug nce heev. Tej zaum cov ntshav nyob rau hauv mob loj heev cov kab mob tshwm sim tsis paub qab hau hlwb - metamyelocytes (tub ntxhais hluas) thiab myelocytes. Nce tus naj npawb ntawm band hlwb, myelocytes thiab metamyelocytes tsos hu ua ib tug ua haujlwm rau sab laug ntawm leukocytes. ua haujlwm mis yog feem ntau nrog rau lub advent ntawm toxigenic granularity rau nkaug thiab segmented qe thiab basophils lawv cytoplasm.

Tej kev hloov nrog Neutrophil mob inflammatory kab mob, poob siab lub xeev, infarction, ntau yam intoxications. Tshwj xeeb tshaj yog cov lus hais ua haujlwm mus rau sab laug uas mob myelocytic leukemia. Nyob rau hauv no kab mob, segmented qe thiab txo sharply raws li ib tug feem pua thiab nyob rau hauv tsis lus. Nyob rau hauv cov mis mos predominate nkaug thiab tsis paub qab hau hlwb. Txo tus naj npawb ntawm segmented qe ua rau lub fact tias tus tiv thaiv muaj nuj nqi ntawm leukocytes tsawg. Nws hawv ua phem rau qhov sib ntxiv ntawm ntau yam kab mob.

Yuav txo tau ntawm segmented thiab band qe yog hu ua neutropenia. Nws feem ntau yog tshwm sim nyob rau hauv lub keeb kwm yav dhau ntawm lub dav txo nyob rau hauv cov ntshav dawb. Xws li ib tug lub xeev tshwm sim nyob rau hauv mob thiab kab mob, feem ntau tom qab tau txais cytostatics, tom qab tawg txoj kev kho, cov ntshav kab mob xws li agranulocytosis thiab aplastic anemia.

Yog li, lub luag hauj lwm ntawm segmented qe yog los tiv thaiv cov neeg los ntawm kab mob. Nyob rau hauv cov kab mob ntawm tus xov tooj ntawm nyiaj nce. Qhov no yog thaws rov los nyob rau hauv qhov kev hloov piv ntawm hlwb nyob rau hauv cov mis ntawm cov ntshav.
