Lymphocytes nce. Qhov no txhais li cas?

Feem ntau thaum noj ntshav tsom qhia tau hais tias nyob rau hauv tib neeg cov ntshav lymphocytes nce. Yuav ua li cas yog tseem muaj tim khawv los xws li ib unpleasant teeb meem no? Tiv thaiv hlwb hu ua lymphocytes (tiv thaiv kab mob) system. Lawv yog ua los ntawm cov pob txha nyob rau hauv lub cev. Cov hlwb yog lub luag hauj lwm rau tus nrog paub txog tej txawv teb chaws kab mob thiab teb rau lawv. Nyob rau hauv thiaj li yuav nrhiav tau tawm yog vim li cas cov kev nce ntawm lawv theem nyob rau hauv cov ntshav, nws yog tsim nyog los nkag siab txog dab tsi cov ntshav mus kuaj qhia tau hais tias. Lymphocytes nce nyob rau hauv Feem ntau, tab sis nws yog tsim nyog los nkag siab txog lawv heev essence.

Muaj ob peb hom ntawm cov hlwb. Vim hais tias T-lymphocytes, generated nyob rau hauv lub thymus (thymus) lub luag hauj lwm rau kev txiav txim cov kev hom microorganisms. Nws yog los ntawm cov hlwb nyob rau ntawm raws sij hawm thiab yog lo lus teb rau lub allergic ntawm pathogenic pathogens. Cov hlwb raug muab faib ua "killers", inhibiting txoj kev loj hlob ntawm kab mob thiab ua puas lub cuam tshuam hlwb ntawm ib tug kab mob; "Pab" txhawb dag zog rau kev tiv thaiv, thiab "suppressors" uas suppress lub cev teb. Qhov no hom ntawm lymphocyte yog hais txog 80% ntawm tag nrho cov.

B-lymphocytes yog ua los ntawm lymphoid cov ntaub so ntswg qog, tonsils, tus po thiab hnyuv. Lawv ua tshuaj (tshwj xeeb cov nqaijrog) uas yog cov kab mob, mob hlwb, cov kab mob thiab kom lawv puas tsuaj. Tus nqi ntawm cov lub cev yuav ncav cuag ib lub hom luj ntawm 15% (tag nrho cov lymphocytes).

Yam tsawg kawg ntawm tag nrho cov nyob rau hauv cov ntshav ntawm tib neeg NK hlwb. Lawv tus naj npawb tsis pub tshaj 10%. Cov hlwb yog lub luag hauj lwm rau kev tiv thaiv los ntawm ntau yam qog thiab kab mob.

Nyob rau hauv ib tug noj qab nyob zoo human hlwb feem ntau raws li ntau raws li 36-40% ntawm tag nrho cov xov tooj ntawm cov qe ntshav dawb. Tej ntaub ntawv no yog sau nyob rau hauv lub tsom xam nyob rau hauv tsis nqe lus raws li nram no: 1,0-3,6 * 10 (9) / L. Nws yog nyob rau cov kev txwv no, cov xov tooj ntawm lymphocytes yog xam qub. Nyob rau hauv thaum yau, lawv theem txawv heev thiab muaj peev xwm yuav hloov. Nyob rau hauv kiag, nws yog los ntawm 9 mus rau 32 * 10 (9) / L. Nrog lub hnub nyoog, cov xov tooj yog txo kom 18 xyoo thiab mus txog tsis nuj nqis 1-4 * 10 (9) / L.

Lymphocytes nce thaum lub sij hawm tus kab mob (influenza, kis kab mob siab B, kab mob pertussis, qhua pias, rubella), nonviral kab mob (diphtheria, malaria, typhoid kub taub hau, syphilis), tokoplazmoza, ntshav kab mob (lymphoblastic lymphosarcoma). Tej zaum, ua rau tus xov tooj ntawm cov ntshav vim tsawg ntawm cov tshuaj.

Lymphocytes nce nyob rau hauv lub xeev lymphocytosis. Nws ua tim khawv rau qhov kev nce rau hauv tus naj npawb ntawm cov hlwb nyob rau hauv cov ntshav uas yeej tawm ntawm cov ntshav. Nws yog txwv kom muab zais rau hauv 2 hom: tsis thiab txheeb ze. Cov tsos ntawm ib tug tsiaj nyob rau tus kab mob, ntws nyob rau hauv lub cev. Tus kwv tij lymphocytosis, los yog kev nce rau hauv kev faib ua feem ntawm lymphocytes ntawm ib tug concentration lig qub tsis npaum li cas, tshwm sim feem ntau heev. Nws zoo nkaus li nyob rau hauv cov kab mob, uas yuav txo tau lwm yam leukocytes. Tej lymphocytosis yam ntxwv rau tus kab mob, inflammatory kab mob, typhoid kub taub hau, brucellosis.

Tsis lymphocytosis qhia ib txog kev nce rau hauv tus naj npawb ntawm lymphocytes. Nws yog cai nyob rau hauv mob kab mob. Nws yog cov yam ntxwv ntawm rubella, qhua pias, kub taub hau, tuberculosis. Nws zoo nkaus li thiab lymphosarcoma.

Nyob rau hauv ntev kab mob thiab o uas infiltration ntawm lub lesion los ntawm cov lymphocytes, ob hom lymphocytosis nyob rau hauv cov ntshav yuav ua tau cai.

Yog hais tias lub hlwb yog tsa rau cov neeg laus tej zaum nws yuav muaj pov thawj ntawm cov kab mob xws li kab mob mononucleosis, kis kab mob siab, theem nrab syphilis, mob hawb pob, kab mob siab, ntshiab kab mob, endocrine kab mob, Addison tus kab mob, hyperplasia ntawm lub thymus. Feem ntau qhov no tshwm sim thaum uas B12-deficiency anemia, ib tug txo nyob rau hauv ACTH thiab glucocorticoids, ntev yoo mov, ntawm zes qe menyuam hypofunction, acromegaly.
