Qhov txawv ntawm granulocytes thiab agranulocytes yog tias cov granulocytes muaj cytoplasmic granules thaum lub agranulocytes tsis muaj cytoplasmic granules.
Ntshav muaj cov khoom sib txawv. Ntawm lawv, cov qe ntshav dawb lossis leukocytes yog ib lub hlwb loj uas koom nrog kev tiv thaiv thiab tiv thaiv kab mob. Lawv ua hauj lwm raws li lub ntsiab cellular ib feem ntawm cov ntshav. Tsis tas li ntawd, lawv loj dua cov qe ntshav liab tab sis pom muaj tsawg dua piv rau lawv. Tsis tas li ntawd, muaj ob hom qe ntshav dawb. Namely, lawv yog cov granulocytes thiab agranulocytes. Qhov kev faib tawm no yog nyob ntawm ntau yam xws li qhov muaj lossis tsis muaj cytoplasmic granules, cov duab nuclear, affinities rau chav kuaj stains lossis dyes, thiab lwm yam.
Ntxiv mus, tsis zoo li cov qe ntshav liab, cov qe ntshav dawb tuaj yeem tawm hauv cov ntshav los ntawm kev xav tias tus cwj pwm zoo li amoeba kom wriggle los ntawm qhov nqaim capillary pores, thiab ua lawv txoj haujlwm hauv ntau cov ntaub so ntswg. Txawm li cas los xij, lub luag haujlwm tseem ceeb ntawm leukocytes yog tiv thaiv lub cev tiv thaiv kab mob thiab cov khoom txawv teb chaws. Yog li, leucocytes thiab lawv cov derivatives, nrog rau qee cov plasma proteins yog lub luag haujlwm ua rau lub cev tsis muaj zog, hauv ntau cov kab mob siab dua.
YDab tsi yog Granulocytes?
Granulocytes yog ib hom qe ntshav dawb uas muaj cytoplasmic granules. Kev tsim cov granulocytes tshwm sim hauv cov pob txha liab hauv cov pob txha. Tsis tas li ntawd, lawv tuaj yeem sib txawv yooj yim los ntawm cov xim ntawm lawv cov granules thaum stained nrog Wright tus stain. Tsis tas li ntawd, muaj peb hom granulocytes. Namely, lawv yog neutrophils, eosinophils, thiab basophils.
Daim duab 01: Granulocytes
Tawm ntawm lawv, neutrophils yog cov qe ntshav dawb ntau tshaj plaws uas muaj cov nuclei faib ua ib mus rau tsib lobes. Lub luag haujlwm tseem ceeb ntawm neutrophil yog txhawm rau rhuav tshem cov kab mob los ntawm phagocytosis. Eosinophils muaj irregularly zoo li tus nuclei nrog ob lobes, thiab chav kawm, uniform, puag ncig los yog oval-puab granules nyob rau hauv lawv cytoplasm. Tsis tas li ntawd, eosinophils nce ntau thaum lub sijhawm ua xua thiab tseem ceeb heev rau kev noj thiab tshem tawm cov tshuaj txawv teb chaws. Ntawm qhov tod tes, basophils sawv cev qhov tsawg kawg nkaus ntawm cov qe ntshav dawb thiab muaj nyob hauv nruab nrab, S-shaped nuclei. Lawv ua phagocytosis, thiab lawv tso herpin thiab histamine thiab txhawb cov inflammatory teb nyob rau hauv cov kab mob.
Thaum xav txog tag nrho cov qe ntshav dawb, granulocytes suav txog 65% piv rau agranulocytes. Thiab cov granulocytes no muaj ib qho tseem ceeb enzyme uas tsis muaj nyob rau hauv agranulocytes.
Agranulocytes yog dab tsi?
Agranulocytes lossis mononuclear leukocytes yog ib hom leukocytes uas tsis pom cytoplasmic granules. Txij li cov hlwb no tsis muaj granules nyob rau hauv lawv cov cytoplasm lawv tsis teb rau Wright tus stain. Ntxiv mus, muaj ob hom agranulocytes. Namely, lawv yog monocytes thiab lymphocytes.
Daim duab 02: Agranulocytes
Ntawm no, cov monocyte yog cov qe ntshav dawb loj tshaj plaws thiab muaj cov txiv ntoo zoo li tus nees. Saib ntawm lawv cov haujlwm, lub luag haujlwm tseem ceeb ntawm monocyte yog nqa tawm phagocytosis ntawm cov khib nyiab ntawm tes thiab cov khoom txawv teb chaws. Ib lub lymphocyte feem ntau yog hom thib ob ntau cov qe ntshav dawb thiab muaj ib qho loj, kheej kheej kheej kheej. Tsis tas li ntawd, muaj ob hom lymphocytes. Namely, lawv yog T lymphocytes thiab B lymphocytes. T lymphocytes ncaj qha tua cov kab mob, thiab lawv tsis ua cov tshuaj tiv thaiv. Tsis zoo li T lymphocytes, B lymphocytes tsim cov tshuaj tiv thaiv kab mob thiab tso tawm rau hauv cov hlab ntsha kom ncig thiab tawm tsam cov khoom txawv teb chaws. Monocytes tsim 1-7 %, thaum lymphocytes ua 15 mus rau 30% ntawm tag nrho cov qe ntshav dawb hauv tib neeg laus.
Dab tsi yog qhov zoo sib xws ntawm Granulocytes thiab agranulocytes?
- Granulocytes thiab Agranulocytes yog cov qe ntshav dawb.
- Ob leeg ua raws li lub cev tiv thaiv kab mob thaum lub sij hawm tiv thaiv mechanisms.
- Lawv muaj nyob rau hauv cov hlab ntsha.
Qhov txawv ntawm Granulocytes thiab Agranulocytes yog dab tsi?
Granulocytes thiab agranulocytes yog ob hom loj ntawm cov qe ntshav dawb. Raws li cov npe qhia, qhov sib txawv ntawm granulocytes thiab agranulocytes yog qhov muaj thiab tsis muaj cytoplasmic granules. Granulocytes muaj cytoplasmic granules thaum agranulocytes tsis muaj granules. Granulocytes muaj segmented nuclei thaum agranulocytes muaj nonsegmented nuclei. Yog li, lawv raug xa mus ua polymorphonuclear leukocytes thiab mononuclear leukocytes feem. Yog li, peb tuaj yeem xav txog qhov no yog lwm qhov sib txawv ntawm granulocytes thiab agranulocytes. Tsis tas li ntawd, lawv txawv ntawm lub hauv paus chiv keeb thiab. Granulocytes originate nyob rau hauv cov pob txha pob txha thaum agranulocytes originate nyob rau hauv lub lymphoid.
Cov duab hauv qab no muab cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm granulocytes thiab agranulocytes.
Summary – Granulocytes vs Agranulocytes
Leukocytes lossis cov qe ntshav dawb yog ob hom uas yog granulocytes thiab agranulocytes. Granulocytes muaj cytoplasmic granules uas tuaj yeem stained los ntawm Wright tus stain. Hauv kev sib piv, agranulocytes tsis muaj cytoplasmic granules. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm granulocytes thiab agranulocytes. Tsis tas li ntawd, granulocytes muaj lub lobed nucleus thaum agranulocytes tsis muaj lobed nucleus. Lwm qhov sib txawv ntawm granulocytes thiab agranulocytes yog keeb kwm. Granulocytes pib los ntawm cov pob txha pob txha ntawm tib neeg thaum agranulocytes los ntawm lymphoid. Thaum xav txog feem pua ntawm cov granulocytes thiab agranulocytes los ntawm tag nrho cov qe ntshav dawb, granulocytes suav txog 65% ntawm tag nrho cov leukocytes thaum agranulocytes suav txog 35%. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm granulocytes thiab agranulocytes.
