Txo monocytes - lub harbingers ntawm tus kab mob

Monocytes - ib yam ntawm cov loj leukocytes active phagocytic ntshav, uas yog generated nyob rau hauv lub hlwb pob txha. 2-3 hnub tom qab lawv nkag mus rau hauv lub ntsiab ntshav txaus monocytes muaj nyob rau hauv ntaub so ntswg thiab txia mus ua macrophages. Lub ntsiab muaj nuj nqi ntawm monocyte-derived macrophages yog nqus txawv teb chaws cov neeg ua hauj - tshuaj tebchaw, cov nqaijrog, thiab ib lub hlwb. Yog li monocytes pib ib lub cev lo lus teb rau invading txawv teb chaws antigens. Ib tug tseem ceeb expansion ntawm antigens yuav ua monocytes kev txhim kho, thiab nyob rau hauv tej rooj plaub lawv loj hlob sai.

Norma ntshav monocytes

Nruab nrab ntawm cov monocytes nyob rau hauv cov ntshav - los ntawm 1 mus rau 8 feem pua. Txiav txim los ntawm cov feem pua thaum muaj CBC. Monocytes yog nws txo qis thaum noj cov tshuaj, "Prednisolone" thiab zoo sib xws. Qhov feem pua ntawm monocytes mus rau lwm cov phagocytes txiav txim nrog yug me nyuam rau leukocyte. Txo monocytes yuav ua rau ib qho kev nce ntawm cov ntshav dawb, thaum lub uniformity ntawm phagocytes nyob rau hauv feem ntau tus neeg mob yuav tsum havzoov lawv kev sib raug zoo.

Phagocytic ntshav cwj pwm hais tseg soj ntsuam kab mob. Thaum lub sij hawm kev kho mob nrog hwj chim tshuaj txo monocytes yuav qhib kom ua huaj thiab ntse tua cov alien hlwb. Qhov nqi koj tshuav ntawm lub xub ntiag ntawm leukocytes thiab monocytes nyob rau hauv cov ntshav tsub kom lub hauj lwm zoo ntawm kev kho mob.

Dawb ntshav qis, monocytes nce

Pathological dab nyob rau hauv lub cev, txawm lub feem ntau tsis tseem ceeb txaus yuav ua rau ib qho kev nce ntawm monocytes - monocytosis.

Tus kwv tij monocytosis feem ntau nrog los ntawm ib tug tseem ceeb txo nyob rau hauv cov ntshav dawb cell suav, nws yog cov yam ntxwv ntawm neutropenia los yog lymphocytopenia. Txo monocytes, raws li ib tug txoj cai, tsis txhob ua rau ntshai thaum monocytosis yog ib tug kos npe rau ntawm cov hauv qab no kab mob:

• mob myelomonocytic leukemia los yog monocytic;
• myeloblastic leukemia, mob monoblastic leukemia, Hodgkin tus kab mob;
• ua kab mob endocarditis, rickettsial thiab protozoal, kis kab mob;
• lupus, mob caj dab, polyarteritis;
• brucellosis, ulcerative mob plab, enteritis, syphilis.

Qhov tsawg theem ntawm leukocyte

Txo cov ntshav dawb cell count yog hu ua leukopenia. Tus kab mob no yuav tshwm sim los ntawm:

• hloov hlwb pob txha tsim cov ntshav dawb nyob rau hauv tsis txaus ntau;
• kev puas tsuaj ntawm leukocytes ncaj qha mus rau hauv cov hlab ntsha;
• Stagnation ntawm leukocytes nrog tau ncua sij hawm ntawm depot lub cev;
• neutralization ntawm leukocytes nyob rau hauv hlab-majeure yam (los ntawm lub cev qhuav dej los yog poob siab).

Yam rau tus tsim ntawm leukocytes

Adversely cuam tshuam rau qhov tsim los ntawm ntau yam leukocyte inflammatory tshuaj, xws li "Phenylbutazone" "Amidopyrine", "Analgin" thiab "pirabutol". leukopenia kuj pab mus rau txoj kev loj hlob ntawm cov tshuaj ntawm antibacterial txiav txim, "levomitsitin", "sintomitsina", "sulfanilamide". Txo cov theem ntawm leukocytes nyob rau hauv cov ntshav cytostatic cov neeg ua hauj-methotrexate, thiab cyclophosphamide.

Lub ntsiab muaj nuj nqi ntawm cov ntaub so ntswg macrophages, monocytes, qe ntshav dawb thiab ib tug xov tooj ntawm lwm leej lwm tus yog cov haum ntawm cov teeb meem hais tias cas nyob rau hauv lub cev. Qhov no tshwm sim peculiar ntshav purification nyob rau hauv tus txheej txheem ntawm phagocytosis, nyob rau dominiruschaya monocytes lub luag hauj lwm yog muab raws li qhov loj tshaj plaws phagocytic hlwb.

Monocytes kuj yuav tsitoskopicheskoe ntxim rau cov kev mob hlwb thiab malaria pathogens. Qhov tsom xam tshwm sim "txo monocytes" txhais tau tias lawv lub cev yog me dua nws yuav tsum, tab sis vim hais tias lawv yog tsis tshua zoo, tab sis lawv cov kev khiav dej num khaws cia.
