Lymphocytes yog poob - vim li cas?

Lymphocytes - ib tug tshwj xeeb tib neeg lub hlwb muaj feem xyuam rau cov leukocytes pab pawg neeg. Lawv yuav mus rau hauv lub thiaj li hu ua qe ntshav dawb. Cov tub ntxhais ntawm lawv loj heev. Lawv yog ua nyob rau hauv lub hlwb pob txha, thiab lub embryo - tsis tsuas nyob rau hauv lub hlwb pob txha, tab sis kuj nyob rau hauv lub siab thiab qia hlwb. Nws yog ib qho tseem ceeb rau hwm cov kev cai ntawm lub cev lymphocytes - tus nqi thiab piv rau cov zoo li hlwb. Uas lymphocytes yog lub ntsiab quab yuam ntawm lub cev, sib ntaus sib tua nrog tag nrho cov xaiv ntawm intrusions los ntawm sab nraum - nrog teeb meem kab mob thiab cov kab mob. Qhov no tseem ceeb ntawm cov hlwb, lymphocytes, thiab yog hais tias txo, nws yuav ua tau ib tug teeb meem nyob rau hauv nws tus kheej rau lub cev, vim hais tias nws tiv thaiv nws txo qis, thiab ib tug worrying kos npe rau, taw uas tus neeg mob tsis yog tag nrho noj qab nyob zoo. Lymphocytes tsis tsuas sib ntaus sib tua tawm tsam "invaders", tab sis kuj yuav ua cov tshuaj, uas ces yuav tsum tau tiv thaiv kab mob.

Muaj kom meej meej tseg cov kev cai ntawm lymphocytes. Ib tug neeg laus yuav tsum yog los ntawm ib txhiab mus rau peb txhiab lymphocytes ib microliter ntawm cov ntshav. Yog hais tias peb coj tus piv ntawm lymphocytes thiab lwm yam ntshav dawb, nyob rau hauv lwm yam lus - leukocyte mis, lub hlwb yuav tsum tau los ntawm nees nkaum rau peb caug-tsib feem pua. Tsuas yog ob feem pua ntawm tag nrho cov xov tooj ntawm lymphocytes yog tsiv nrog rau cov ntshav los ntawm lub cev, thiab tus so yog nyob rau hauv cov pob txha cov ntaub so ntswg.

Nyob rau hauv cov me nyuam, tus nqi ntawm lymphocytes yog ho muaj dua. Rau cov me nyuam mos, uas yog tsis thiab plaub hnub tom qab yug tus me nyuam, lymphocytes cai - yog los ntawm 22 mus rau 25 feem pua. Tus me nyuam, uas tau ua ib lub lim tiam los ntawm lub sij hawm yug, yeej yuav muaj 40-42%. Yog hais tias tus me nyuam yog tsis rau xyoo, nws tus nqi - 60-65%. Thaum tus me nyuam puv rau xyoo thiab mus txog rau kaum yim xyoo ntawm lub hnub nyoog muaj tus nqi ntawm lymphocytes yog muaj tseeb laus.

Yog hais tias neeg laus cov ntsiab lus nyob rau hauv cov ntshav lymphocytes yog tsawg tshaj li 1.0 * 109 / L, ces xws li ib tug lub xeev yog ncav hu ua lymphocytopenia. Yog hais tias hlwb yog nws txo qis, lymphopenia yuav tau muab faib mus rau hauv ob lub ntsiab hom: tsis los yog txheeb ze. Indicators ntawm txhua tus ntawm cov tsiaj lymphocytopenia muaj lawv tus kheej tseem ceeb. Yog hais tias lub lymphocytes leykoformule downgraded, thiab lawv muaj pes tsawg nyob rau hauv cov ntshav yeej muaj tseeb, peb yuav tau tham txog tus txheeb ze lymphocytopenia. Tus kwv tij lymphopenia yog ib qho taw qhia ntawm cov kab mob inflammatory, uas yog nrog los ntawm ib tug muaj zog naj npawb ntawm cov qe nyob rau hauv cov ntshav. Qhov no yuav ua tau mob ntsws txheem dej los yog ib tug tej yam ntawm suppurative o. Yog hais tias lub lymphocytes yog txo nyob rau hauv cov ntshav, ib tug mob hu ua tsis lymphocytopenia. Yog vim li cas tej zaum yuav HIV, nyob rau lub lymphocytes raug tua. Tiam sis ntau tshaj feem ntau txo lymphocytes yog ib tug kos npe rau ntawm tus kab mob nyob rau hauv cov ntshav, nyob rau hauv uas lub qe inhibited hematopoiesis.

Nws feem ntau tshwm sim hais tias txo lymphocytes nyob rau hauv cev xeeb tub cov poj niam. Yog vim li cas tsis yog yooj yim: Yog hais tias nws twb tsis yog li ntawd, cov poj niam dawb ntshav hlwb uas yog lub luag hauj lwm rau kev nkag mus kawm txoj kev kawm tshuaj nyob rau hauv lub cev, yuav thaiv nws tus txiv cov noob, uas ua nyob rau hauv cev xeeb tub yuav tsum tau tsuas yog tsis yooj yim sua los yog yuav tau dhau mus lawm nrog teeb meem, thiab tus me nyuam yuav yug muaj mob, muaj zog heev. Txawm li cas los, Yog hais tias ib tug ua txhaum ntawm lub cai ntawm lymphocytes nyob rau hauv cov poj niam uas nyuam qhuav tau ua cev xeeb tub, nws tsis yog ib qho yooj yim lymphopenia, thiab ib tug tshwj xeeb txoj kev nyob rau hauv uas lub lymphocytes lub luag hauj lwm rau lub inhibition ntawm lub cev lo lus teb yog tshuab txais thiab nce nyob rau hauv lawv cov xov tooj, thiab cov neeg uas yog tawm tsam nrog alien kab mob, cov inhibited thawj, tus xov tooj ntawm lawv yog txo. Nyob rau ntawm lub sij hawm, raws li cov nws txo qis T-lymphocyte Heller, nce T suppressor.

Txawm li cas los, Yog hais tias ib tug cev xeeb tub poj niam tau poob tooj ntawm dawb hlwb lub luag hauj lwm rau lub cev lo lus teb, nws tsis tau txhais hais tias lub cev ntawm lub neej yav tom ntej leej niam tsis tau muaj kev tiv thaiv, vim hais tias cov inhibition ntawm qhov ua kom ntawm lymphocytes yog hloov los ntawm cov Neutrophil-tiam hlwb nrog phagocytes. Los ntawm txoj kev, Yog hais tias ib tug cev xeeb tub poj niam yog tsis txo lymphocyte-Heller nrog nce suppressor lymphocytes, thaum Heller tos txais cov txawv teb chaws tshuaj txeem lub tsho me nyuam, zoo tua cov me nyuam hauv plab, ua rau rho me nyuam tawm los yog nchuav me nyuam. Tab sis tam sim no zaum tau pom ib txoj kev tawm ntawm no qhov teeb meem. Yuav kom muaj tau downgraded lymphocytes Heller nyob rau hauv ib tug cev xeeb tub, feem ntau nrog kev tso cai los ntawm nws tus txiv, leej txiv rau yav tom ntej, lub txhaj tshuaj tiv thaiv ntawm cev xeeb tub cov poj niam nrog tus txiv suppressors uas normalizes tus txheej txheem ntawm cev xeeb tub.
