Lub luag haujlwm tseem ceeb hauv kev tsim cov tshuaj tiv thaiv kab mob hauv tib neeg lub cev yog ua los ntawm plasma cell. Nws yog hais txog nws yuav tham.

Plasmocytes thiab lawv cov laj thawj

Yog li, paub meej ntxiv. Plasma cells yog ib pawg ntawm cov qe ntshav dawb uas tsim cov tshuaj tiv thaiv. Lawv tsim los ntawm B-lymphocytes.

Ib txhia ntseeg yuam kev tias cov hlwb no tsim teeb meem uas qhia tias muaj cov kab mob pathology. Plasma hlwb yog lub cev cov tshuaj tiv thaiv rau kev ua ntawm lwm yam. Lawv nyob tas li nyob rau hauv nws: nyob rau hauv cov qog nqaij hlav, nyob rau hauv tus po, thiab kuj nyob rau hauv cov pob txha liab pob txha.

Tus kws tshaj lij zoo, tau pom cov ntshav plasma hauv kev tshuaj ntsuam dav dav, yuav txiav txim siab tias tus neeg mob tsis ntev los no muaj ib qho ntawm cov kab mob sib kis. Thiab tseem hais tias tus kab mob no tseem nyob hauv lub cev.

Plasmocytes tshwm sim los ntawm kev kis kab mob, o. B-lymphocytes nkag mus rau cov qog ntshav, uas lawv hloov mus rau hauv cov ntshav plasma, uas tsim cov tshuaj tiv thaiv kab mob los tiv thaiv kab mob.

qauv thiab kev ua haujlwm

Lub plasma cell muaj ib puag ncig lossis oval. Nyob rau hauv lub microscope, koj tuaj yeem pom cov nucleus nrog heterochromatin. Nws yog surrounded los ntawm cytoplasm. Nws muaj ib lub cuab yeejGolgi. Tus so ntawm cytoplasm muaj cov qauv ntom.

Plasmocytes yog ib feem ntawm tib neeg lub cev tiv thaiv kab mob, lawv lub luag haujlwm tseem ceeb yog tsim cov tshuaj tiv thaiv tshwj xeeb - immunoglobulins. Nyob rau tib lub sijhawm, cov hlwb nco tau tsim uas ua rau cov tshuaj tiv thaiv antigens (tshuaj txawv teb chaws thiab txaus ntshai rau lub cev) ob peb lub hlis thiab txawm tias xyoo tom qab thawj qhov tsos.

Yog tias tib yam khoom nkag mus rau lub cev dua tom qab qee lub sijhawm, lub npe hu ua "cov hlwb nco" tam sim ntawd tsim cov tshuaj tiv thaiv. Txawm li cas los xij, lawv tsis nkim sij hawm lees paub cov antigen.

Tus qauv ntawm cov ntshav plasma. Cov ntaub ntawv hais txog lawv hauv kev tshuaj ntsuam

Ib plasma cell hauv cov ntshav ntawm tus neeg laus yuav tsum tsis tuaj. Hauv cov menyuam yaus, nws tuaj yeem muaj nyob rau hauv ib qho nyiaj (ib lossis ob txhiab leej lwm tus hauv cov ntshav). Hauv cov menyuam yug tshiab, tus nqi ntawm cov ntshav plasma yuav tsum yog ib mus rau ob feem pua ntawm cov hlwb hauv cov ntshav.

Tsis tas li ntawd, muaj cov hlwb hauv cov tonsils, hauv cov mucous ntawm lub qhov ntswg, kab mob ua pa thiab plab yog suav tias yog qhov qub. Yog li, tus kws kho mob pom qhov nce qib ntawm cov ntshav plasma hauv cov ntshav, thiab lawv qhov txo qis tsis raug kuaj pom, vim qhov no tsis cuam tshuam rau lub xeev kev noj qab haus huv.

Rau kev tshuaj ntsuam, ntshav yog muab los ntawm cov leeg lossis los ntawm tus ntiv tes. Txij li txoj kev thib ob yog pheej yig dua thiab yooj yim dua, nws tau ua ntau zaus.

Nws yog ib qho tseem ceeb rau tus neeg mob yuav tsum nco ntsoov tias nws yuav tsum tau xeem thaum sawv ntxov thiab lub plab khoob kom ntseeg tau siab tshaj plaws ntawm cov txiaj ntsig. Qhov zoo tshaj plaws yog suav cov ntshav tag, raws li nws tso cai rau koj txheeb xyuasntau yam kab mob ntshav, nrog rau cov laj thawj rau kev tsis zoo ntawm kev noj qab haus huv ntawm tus neeg mob.

Yog tias muaj ntau cov ntshav plasma

Yuav ua li cas hauv qhov no? Txij li thaum nws tau hais saum toj no tias tsis muaj cov ntshav plasma hauv lub cev, qhov nce ntawm lawv cov lej, tau kawg, tuaj yeem cuam tshuam cov qauv ntawm leukocytes. Nws kuj qhia tau hais tias muaj cov txheej txheem pathological hauv tib neeg lub cev. Cov ntsiab lus ntawm cov ntshav plasma ntau dhau tuaj yeem ua rau muaj kab mob hnyav. Koj yuav tsum tau xyuam xim rau qhov no. Piv txwv li:

- kab mob xws li rubella, kab mob qhua pias, kis kab mob mononucleosis (feem ntau) thiab qhua pias;

- tshwm sim ntawm plasmacytoma (malignant qog);

- tuberculosis, mob septic, mob ntshav qab zib, uas cov antigen nyob hauv cov ntshav tau ntev;

- raug ionizing hluav taws xob;

- mob qog noj ntshav.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev kuaj xyuas raws sij hawm thiab kev kho mob tuaj yeem cawm koj ntau yam teeb meem yav tom ntej. Thiab kev kuaj mob raws sij hawm yuav pab tus kws kho mob kom nkag siab qhov ua rau ntawm qhov tsis zoo no.
