YLymphocytes vs Leucocytes
Ib tug neeg laus muaj qhov nruab nrab ntawm 5dm3ntawm cov ntshav, uas yog cov ntaub so ntswg. Hauv cov ntshav plasma, cov qe ntshav raug tshem tawm. Muaj ntau hom qe ntshav uas ua rau 45% ntawm cov ntshav ntim (Taylor li al, 1998). Cov no yog cov qe ntshav liab (erythrocytes), cov qe ntshav dawb thiab platelets, uas suav tias yog cov khoom tawg ntawm tes. Cov qe ntshav dawb hu ua leucocytes, thiab muaj ob pawg loj ntawm cov qe ntshav dawb. Cov no yog polymorphonuclear leucocytes (Granulocytes), uas ua rau 70% ntawm cov qe ntshav dawb, thiab mononuclear leucocytes (Agranulocytes) ua 28% ntawm cov qe ntshav dawb (Taylor et al, 1998).
YLeucocytes
Leucocyte (cov qe ntshav dawb) yog ib lo lus sib sau ua ke rau polymorphonuclear leucocytes (Granulocytes) thiab mononuclear leucocytes (Agranulocytes). Cov hlwb no loj dua cov qe ntshav liab thiab txawv ntawm cov qe ntshav liab. Lawv tsis muaj hemoglobin uas yog lub luag haujlwm rau xim liab. Cov qe ntshav dawb ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv mechanism, hauv lub cev. Los ntawm kev noj cov khoom txawv teb chaws lossis tsim cov tshuaj tiv thaiv, lawv tiv thaiv lub cev los ntawm cov kab mob. Muaj amoeboid txav, lawv muaj peev xwm nyem los ntawm qhov hws kom ncav cuag cov ntaub so ntswg.
cov qe ntshav dawb tau muab faib ua ob pawg raws li seb lawv muaj granules lossis tsis nyob hauv lawv cov cytoplasm. Yog li, Granulocytes, uas muaj granules nyob rau hauv lawv cytoplasm, tau muab faib ntxiv rau hauv neutrophils, eosinophils, thiab basophils. Txhua pab pawg no muaj nws tus yam ntxwv tshwj xeeb. Feem ntau, pob txha pob txha yog keeb kwm ntawm peb pawg no. Agranulocytes tsis muaj granules hauv lawv cytoplasm muaj ob pawg hu ua monocytes thiab lymphocytes.
Lymphocytes
Lymphocyte yog cov qe ntshav dawb, uas tsis muaj granules hauv nws cytoplasm; Yog li, hu ua Agranulocytes. Ntawm cov qe ntshav dawb hauv cov ntshav, 28% yog Agranulocytes thiab 24% ntawm Agranulocytes yog lymphocytes. Thymus caj pas thiab cov ntaub so ntswg lymphoid tsim cov lymphocytes los ntawm cov hlwb los ntawm cov pob txha pob txha. Lawv muaj kev txwv amoeboid txav (Taylor li al, 1998). Lub neej ntawm cov hlwb no txawv ntawm ntau hnub mus txog ntau tshaj kaum xyoo.
Cov hlwb no muaj lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev tiv thaiv. Lawv muaj peb hom hlwb sib txawv. Lawv yog hom T thiab B hom thiab Natural killer (NK) hlwb. Ob leeg T thiab B hlwb ua haujlwm ntawm qhov tshwj xeeb ntawm cov khoom txawv teb chaws xws li cov kab mob. Piv txwv li, tsim cov tshuaj tiv thaiv kab mob lossis tua cov qog hlwb thiab tsis lees txais cov kab mob uas lawv tiv thaiv lub cev los ntawm kev kis kab mob. Ntuj killer cells kuj ua rau cov qog thiab kis kab mob. Lymphocytes tuaj yeem pom hauv cov ntaub so ntswg hauv nruab nrab thiab cov kabmob xws li tonsils, cov qog ntshav qog.
Qhov txawv ntawm Leucocytes thiab Lymphocytes yog dab tsi?
• Lymphocytes yog hom leucocytes. Txawm hais tias lymphocytes muaj ntau qhov sib xws nrog leucocytes, lymphocytes muaj cov yam ntxwv tshwj xeeb.
• Leucocytes muaj feem pua ntawm cov ntshav siab thaum cov lymphocytes yog vey me me ntawm cov ntaub so ntswg.
• Qee cov leucocytes muaj granules nyob rau hauv lawv cytoplasm, whereas lymphocytes tsis muaj granules nyob rau hauv lawv cytoplasm.
• Lymphocytes muaj peb pawg; B hlwb, T hlwb, thiab Natural killer (NK) hlwb, tab sis leucocytes muaj ntau sub pawg.
• Leucocytes muaj lub luag haujlwm sib txawv hauv kev tiv thaiv cov txheej txheem xws li zom cov kab mob, ua cov tshuaj tiv thaiv histamine, thaum cov lymphocytes lub luag haujlwm yog txheeb xyuas cov antigens thiab tsim cov tshuaj tiv thaiv lossis tua cov qog hlwb thiab tsis lees txais cov grafts lawv tiv thaiv lub cev los ntawm kev kis kab mob.
