Lymphocyte beziswe - kutheni?

Lymphocyte - a iiseli ezikhethekileyo zabantu enxulumene qela leukocytes. Baya kuba loo nto ibizwa ngokuba yinkqubela-iiseli ezimhlophe zegazi. Undoqo zabo ezinkulu kakhulu. Bona yenziwa ngumongo wethambo, bese umbungu - hayi kuphela ukuba umongo, kodwa esibindini ze isiqu iiseli. Kubalulekile ukuba bahloniphe imithetho lymphocyte zomzimba - isixa kunye nomlinganiselo ukuya iiseli ezifana. Ukuba lymphocyte amandla ezingundoqo umzimba, besilwa yonke iintlobo intrusions evela ngaphandle - kunye kwiintsholongwane eziyingozi. Le ukubaluleka ezi seli, lymphocyte, yaye ukuba zancitshiswa, kunokuba yingozi ngokwayo umzimba, ngokuba wakhe wokhuselo ubuza, kwaye umqondiso ukhathazekile, ebonisa ukuba isigulana ayikho yonke impilo entle. Lymphocyte kweli dabi kuphela "bahlaseli", kodwa ukuba ukhuphe izilwa-buhlungu, apho ke uya kuba nako ukumelana nezifo.

Kukho imithetho ezichazwe ngokucacileyo lymphocyte. Omdala kufuneka ukusuka lymphocyte amawaka ukuya kumawaka amathathu microliter ngalinye legazi. Ukuba ngaba sithatha umlinganiselo phakathi lymphocyte kunye nezinye iiseli ezimhlophe zegazi, ngamanye amazwi - indlela leukocyte, iiseli kufuneka athathe ukusuka amabini ukuya kumashumi amathathu anesihlanu ekhulwini. amabini ekhulwini kuphela inani elipheleleyo lymphocyte azamazama kunye negazi ngomzimba, kwaye ezinye kwi ijwabu ithambo.

Ebantwaneni, izinga lymphocyte na aphezulu kakhulu. Ukuze umntwana, lowo neentsuku ezine emva kokuzalwa, lymphocyte norm - kunama-22 ukuya kuma-25 ekhulwini. Umntwana, owenza ngeveki ngexesha wokuzalwa, akunakubakho 40-42%. Ukuba umntwana emithandathu iminyaka, izinga layo - 60-65%. Xa umntwana ujika iminyaka emithandathu ubudala yaye ukuya kutsho kwiminyaka elishumi elinesibhozo ubudala izinga lymphocyte na omdala oluchanekileyo.

Ukuba abadala xa lymphocyte igazi ngaphantsi kwe 1.0 * 109 / L, ngoko ke urhulumente eso kuthiwa lymphocytopenia ngokwenzululwazi. Ukuba iiseli zifingiwe, lymphopenia lungohlulwa lube iintlobo ezimbini eziphambili: ongowona okanye isalamane. Izalathi si zokunikwa ngalunye kwezi ntlobo lymphocytopenia abe ukubaluleka zabo. Ukuba lymphocyte leykoformule zathotywa, yaye inani labo egazini lichanekile, sithetha lymphocytopenia isalamane. lymphopenia Relative sisalathisi kwezifo ukudumba, ezo zihamba inani elandileyo neutrophils ezifumaneka egazini. Oku kunokuba semiphunga okanye uhlobo oluthile ukudumba suppurative. Ukuba lymphocyte ziyancipha egazini, imeko ekuthiwa lymphocytopenia epheleleyo. Isizathu abe HIV, apho lymphocyte ayabulawa. Kodwa lymphocyte rhoqo ngakumbi kuncitshiswa asisimanga izifo egazini, apho ihlume ekhululeke hematopoiesis.

Kudla ngokuthi kuncitshiswa lymphocyte e abafazi abakhulelweyo. Isizathu ilula: Ukuba bekungenjalo, iiseli ezimhlophe basetyhini igazi ukuba unoxanduva lokufaka izinto zokufunda emzimbeni, kuya kuvala imfuza kayise, nto leyo ukukhulelwa bekuya kuba yinto nje akunakwenzeka okanye abapase iingxaki, kwaye umntwana wayeza kuzalelwa ogulayo, siswele kakhulu. Noko ke, ukuba waphula udidi lymphocyte kwabasetyhini kutshanje abaye bakhulelwa, akukho lymphopenia lula, yaye inkqubo ekhethekileyo apho lymphocyte unoxanduva inhibition le omzimba luyasebenza kwaye nokwanda ngangenani lazo, yaye abo batsala nzima nezinto ezingaqhelekanga, ngokomkhethe elinganeno kuqala, inani kubo lifinyele. Ngelo xesha, njengoko bewuhlisele T-lymphocyte Heller, ukwanda T suppressor.

Noko ke, ukuba umfazi omithiyo liye lehla inani leeseli ezimhlophe linoxanduva omzimba, loo nto ayithethi ukuba umzimba unina elizayo ukuba ayakhuselwa, kuba inhibition ka ukusebenza lymphocyte ithathwa yi iiseli neutrophil-isizukulwana kunye ziiphagocytes. Ngendlela, ukuba umfazi okhulelweyo nto kuncitshiswa lymphocyte-Heller nokonyuka lymphocyte suppressor, lo gama Heller ngokubulisa kwamagciwane kusichukumisa ngumkhaya, ngempumelelo ukubulala umntwana, ebangela isisu okanye kwezisu. Kodwa ngoku oosonzululwazi baye bafumana indlela yokuphuma kule meko. Ukuze baye .o lymphocyte Heller ngendlela okhulelweyo, ngokufuthi kunye kwemvume umyeni wakhe, uyise elizayo, ekugonyweni abafazi abakhulelweyo kunye suppressors enendoda normalizes inkqubo yokukhulelwa.
