Limfosaytis kordhay dhiigga, sababo in la elucidated

Unugyada siistemka difaaca aadanaha: - limfosaytis - ka tirsan tahay koox leukocyte of agranulocytes caddaan ah iyo in la abuuro xaalado for dhismaha difaaca humoral oo gacanta. difaac Humoral yeesho antibodies oo gacanta ku bixisaa taabashada unugyada dhibanayaasha. limfosaytis sidoo kale u dhaqmaan sidii goobjoogayaal unugyada kale ee dhiigga iyo dejisa hawlahooda, haddii loo baahan yahay.

Limfosaytis iyo lymphoblasts

Limfosaytis - hogaanka waxyaalaha gacanta nidaamka oo dhan difaaca jidhka dadka, taas oo galo dhiigga ka dhuuxa ka dibna shaqeeyaan firfircoon uga unugyada lymphoid ah. Haddii kordhay limfosaytis ee dhiiga, sababaha for this baahida cadeeyo degdeg ah, oo ugu horreyn u baahan in la sameeyo falanqayn shaybaarka caadiga ah. In xisaab jajab lymphocyte dhiigga dadka waaweyn loogu tala 20 - 35 boqolkiiba tirada guud ee unugyada cad. Qaar iyaga (2%) waa in wareegga lacag la'aan ah in qulqulka dhiigga durugsan, oo boqolkiiba 98% waa in unugyo ah. Sida laga soo xigtay limfosaytis oo ay sifooyinka morphological qaybsan yihiin laba qaybood: granular weyn (unugyada NK immunoblast, lymphoblasts ah) iyo yar (T-cells B iyo-unugyada). All of unugyada kuwanu waa firfircoon oo lymphoblasts ay lug ku leeyihiin geeddi socodka difaaca badan ka yar. Haddii aad u hubiso ka kooban sare ee limfosaytis ee dhiigga, taas oo macneheedu yahay in isbeddel xun jirka ee ka dhacay, waxaa jiray il qarsoon ee caabuqa caabuq ama maxaliga ah.

group lymphocyte

unugyada B ogaado cudur-dhismeedka shisheeye cabaar galay jidhka. Isla waqtigaas ay soo saaraan Britain protein, in takhalusi karaa wakiilada waxyeello ah. T-unugyada baabbi'iyo cudur dayactirka ku sugan wajiga firfircoon, ka hortagga ay fuqday. limfosaytis kordhay ee dhiigga, sababaha dadkan laga yaabaa in aysan garan waayo, waxaa lagu ogaan karo baaritaan dhiig. limfosaytis NK xakameeyo tayada unugyada jidhka oo dhan ayaa. Isla waqtigaas waxay baabbi'in unugyada, ku dhaqan la'aanta, sida unugyada kansarka. limfosaytis T noqonaya 70-80% tirada guud ee B-unugyada waa in cabirku yahay 15-20%, iyo limfosaytis ugu yar tiro ahaan NK, ay content ma aha in ka badan 5-10%. Haddii kordhay limfosaytis ee dhiigga, sababaha waxaa laga yaabaa kala duwan, laakiin ay dhacdo in kasta oo ay tahay calaamad u tahay in jidhka ma aha oo dhan xaq u leeyihiin.

pathogenesis

Limfosaytis wada jir ah ula qaybaha ay kelli caawin fuliyo pathogenesis ee deficiency difaaca, cudurrada faafa, kansarka, iyo cudurada xasaasiyad, colaadaha beerista iyo, ka sii muhiimsan, cudur shalalka. Inta uu hawlgalka socday kordhin kartaa heerka limfosaytis oo lymphocytosis muuqaalka, taasi dhacdo at jawaab ku filan in ay hawl antigenic. In kiiska jiro in la kordhiyo tirada limfosaytis, waxa ay la micno bilowgii dagaal unugyada la cudur. Laakiin sidoo kale waxaa ka soo bixi kara hoos u heer, lacala haddii jawaab ku filneyn in kicinta la cudur ka dibna lymphopenia.

fataahadda of limfosaytis

In nidaamka bukaan eegida, waxaa leukemoid reaction nooca lymphatic, taas oo ay jirto qaab la muuqaalada leukaemia daro ba'an. Dareen-celinta noocan oo kale ah waa in mononucleosis faafa, qaaxada, waraabowga iyo brucellosis. mononucleosis faafa - natiijo ah ee infakshan fayras, inta badan ku dhacdaa carruurta, lagu gartaa heer sare ah leukocytosis sabab u limfosaytis, taas oo dabcan cudurka bartaan tayada cusub duwanaanta morphological. dhiig ayaa la xoojiyey limfosaytis atypical, oo leh calaamado xuduntii Kobac iyo cytoplasm kordhay. Si kastaba ha ahaatee, markii cudurka by limfosaytis in dhiigga kor u kacay, sababaha loo aqoonsado doonaa oo reebay intii suurtogal.
