Lymphocyte Ukwanda egazini: izizathu ukuba cacisa

Iiseli zamajoni omzimba yabantu - lymphocyte - kuba iqela leukocyte of agranulocytes ezimhlophe kunye nokudala iimeko ukuze kwakhiwe okukwazi humoral kunye zeselula. okukwazi Humoral kuphuhliswa izilwa-buhlungu kunye iseli inika ukuqhagamshelana kunye namaxhoba iiseli. lymphocyte kwakhona ukusebenza sibukele ezinye iiseli zegazi nokulawula imisebenzi yabo, ukuba kuyimfuneko.

Lymphocyte kunye lymphoblasts

Lymphocyte - into belawula izinto cellular iyonke amajoni omzimba emzimbeni womntu, leyo ngenisa igazi wamathambo uze asebenza kokubonakalayo ijwabu lymphoid. Ukuba anda lymphocyte egazini, izizathu kwisinyanzeliso ingcaciso ngoko nangoko, kunye nemfuneko kuqala ukwenza uhlalutyo kwilebhu eqhelekileyo. Ngo-akhawunti lymphocyte igazi iqhekeza omdala-20 - 35 ekhulwini inani lilonke iiseli ezimhlophe. Ezinye zazo (2%), i ejikeleza simahla kwi ukuhamba kwegazi peripheral, kunye nama-98% na emzimbeni. Ngokutsho lymphocyte libe neempawu morphological zahlulwe iindidi ezimbini: granular enkulu (iiseli NK immunoblast, lymphoblasts) ezincinci (T-iiseli no-B-cells). Zonke ezi iiseli ezisebenzayo kunye lymphoblasts inxaxheba kwiinkqubo wokugonyeka kancinci kakhulu. Ukuba ukhangela isiqulatho aphezulu lymphocyte egazini, nto leyo ethetha ukuba utshintsho ezingentle umzimba baye kwenzeka, kwakukho umthombo ezifihlakeleyo osulelo okanye ukudumba zasekuhlaleni.

iqela lymphocyte

iiseli B awayiboni ezisegazini isakhiwo yalapha zingene emzimbeni. Ngelo xesha linye Avelisa molekyuli protein ukuba Nokwethisa arhente eziyingozi. T-iiseli kutshabalalisa ezisegazini ukugcina omzimba kwisigaba esebenzayo, ukuvimbela ziba yayo. lymphocyte Ukwanda egazini, izizathu aba bantu abazi, ziyazibhaqekela yi uvavanyo lwegazi. NK lymphocyte ukulawula umgangatho kwiiseli wonke umzimba. Ngelo xesha linye konakalisa iiseli,-non ukungathotyelwa, ezifana iiseli nomhlaza. lymphocyte T i-70-80% yenani lilonke B-iiseli bakwimeko umlinganiselo ka-15-20%, kunye lymphocyte nk kakhulu ngamanani amancinci, isiqulatho yabo ingabi ngaphezu kwe-5-10%. Ukuba anda lymphocyte egazini, izizathu isenokuba ezahlukeneyo, kodwa kunjalo na umqondiso ukuba umzimba konke kulungile.

Pathogenesis

Lymphocyte kunye namacandelo abo ezinto ukunceda ukuphumeza Pathogenesis of intswelo omzimba, izifo ezosulelayo, umhlaza, kunye nezifo negazi, ungquzulwano ukufakela, okona kubaluleke kakhulu, isifo samathambo. Ngexesha ukusebenza kunokwandisa umgangatho lymphocyte nenkangeleko lymphocytosis, oku kwenzeka impendulo eyaneleyo umsebenzi antigenic. Ukuba kukho inani elandileyo lymphocyte, oko kuthetha ekuqaleni ekulweni iiseli kunye nezakhi. Kodwa kwakhona kuza nciphisa inqanaba, kwimeko yezimvo ngokwaneleyo ukuba uvuselelo kunye nezakhi uze khona lymphopenia.

morphology lymphocyte

Ukuziqhelisa lwezonyango, kukho leukemoid reaction uhlobo emithanjeni, apho kukho iphethini iimpawu wegazi ezinganyangekiyo okanye bukhali. abasabela anjalo kulo mononucleosis ezosulelayo, isifo sephepha, ngegcushuwa kunye nesifo sokuphunza. mononucleosis esosulelayo - isiphumo igciwane lohlobo, abaninzi kwande ebantwaneni, ebonakala kwinqanaba eliphezulu leukocytosis ngenxa lymphocyte, nto leyo ngethuba sifo bafumane iimpawu ezintsha zeyantlukwano morphological. Igazi ahlanganiswe lymphocyte Nedlac, kunye iimpawu dysplasia nucleus kunye nokunyuka kukho icytoplasm. Xa kunjalo, xa kwafunyaniswa ukuba ngokwanda lymphocyte egazini, izinto ziya kuchongwa mazwe kangangoko kunokwenzeka.
