Yakawedzera lymphocytes muropa; zvikonzero kuti elucidated

The masero masoja dzevanhu gadziriro - lymphocytes - ndezvaJehovha leukocyte boka agranulocytes chena nokusika zvinhu nokuda paumbwe humoral uye cellular kutapata. Humoral kutapata hwapedyo antibodies uye sero rinopa kuonana vanobatwa masero. lymphocytes uyewo kuita sevacherechedzi mamwe masero eropa uye chengetedza mabasa avo, kana zvichidikanwa.

Lymphocytes uye lymphoblasts

Lymphocytes - ari kutonga cellular zvinhu yose zvirwere zviri mumuviri womunhu, vanopinda ropa mumwongo uye ushande kushingaira ari lymphoid tishu. Kana yakawedzera lymphocytes muropa, zvikonzero ichi charehwa nokukurumidza kunyatsotsanangura, uye vanofanira kutanga kuita zvakafanana rabhoritari kuongorora. In ropa lymphocyte chakapatsanurwa vakura nhoroondo kuti 20 - 35 muzana uwandu masero machena. Vamwe vavo (anenge 2%) ari pachena riparadzirwe muropa kuyerera peripheral, uye 98% chiri munyama. Maererano ayo morphological zvatariswa lymphocytes vakakamurwa muzvikamu zviviri: guru granular (NK masero immunoblast, lymphoblasts) uye diki (T-masero uye B-masero). All masero aya zvinoshingaira uye lymphoblasts vanobatanidzwa zvirwere pezvakaitwa ndoda. Kana iwe tarisa yakakwirira zviri lymphocytes muropa, zvinoreva kuti kunaka kuchinja muviri kwakaitika, paiva rine chirwere kana dzomunharaunda kuzvimba yakavanzwa.

lymphocyte boka

masero B wanikidza maantigen mutorwa maumbirwo rakapinza kupinda mumuviri. Panguva iyoyo vakanga pave puroteni mamorekuru kuti neutralize nevamiririri dzinokuvadza. T-masero kuparadza maantigen kuramba kutapata ari kushingaira chokutambudzika, kudzivisa kusunungura kwayo. Yakawedzera lymphocytes muropa, zvikonzero vanhu ava varege kuziva, aonekwa pedyo bvunzo ropa. NK lymphocytes kudzora kunaka mumasero rose muviri. Panguva iyoyo vanoparadza masero, asiri abvume, akadai masero kenza. T lymphocytes vanoumba 70-80% pakati uwandu B-masero vari nhamba 15-20%, uye lymphocytes NK duku zvikuru dziwande, avo kugutsikana haasi kupfuura 5-10%. Kana yakawedzera lymphocytes muropa, zvikonzero zvingava zvakasiyana, asi chero zvakadaro chiri chiratidzo chokuti muviri hausi zvose zvakanaka.

pathogenesis

Lymphocytes pamwe chete kwavo samolecular zvinoriumba kubatsira kushandisa pathogenesis pamusoro Immune Deficiency, zvirwere, kenza, uye sema zvirwere, ndinobvisa kurwisana, uye zvakakoshesa, imwe chirwere autoimmune. Panguva mashandiro kungawedzera pachiyero lymphocytes uye chitarisiko lymphocytosis, ichi chinoitika panguva imwe yakakwana mukupindura antigenic basa. Kana kune nhamba yakawedzera kubva lymphocytes, zvinoreva kutanga kurwisa masero pamwe maantigen. Asi kunogona kuuya pamwero kuderera, kana kuti kukwana Kupindura dzishande pamwe maantigen uye ipapo lymphopenia.

Morphology pamusoro lymphocytes

In kurapwa tsika, pane leukemoid maitiro nhengo dzinobudisa mhando, umo muenzaniso pamwe zviri chirwere kana rikwanise neleukemia. Maitiro akadaro ari kutapuriranwa mononucleosis, tibhii, njovhera uye brucellosis. Zvirwere mononucleosis - mugumisiro akabatwa chirwere, anowanzodanwa kunoitika muna vana, dzinoratidzwa yakakwirira azvipire leukocytosis nokuda lymphocytes, izvo weboka chirwere nounhu itsva morphological kusiyana. Ropa kunowedzerwa pamwe atypical lymphocytes, pamwe zviratidzo dysplasia neerekitironi cytoplasm inowedzerawo. Chero zvazvingava, kana akaonekwa nokuda yakawedzera lymphocytes muropa, zvinokonzera vachaparadzwa kuzivikanwa uye zvachose kure sezvinobvira.
