Hloov hlwb pob txha yog qhov twg? Hloov hlwb pob txha: muaj nuj nqi, qauv

Ib tug ntawm cov tseem ceeb tshaj plaws cov ntaub so ntswg nyob rau hauv peb lub cev yog cov ntshav. Nws yog lub luag hauj lwm rau cov mov ntawm oxygen, uas yog, lub hwj chim ntawm tag nrho cov hlwb, nruab nrog cev thiab tshuab. Nws yog yog li ntawd tseem ceeb nyob rau hauv lub sij hawm mus rau replenish stocks ntawm hlwb uas tsim cov ntshav (erythrocytes, platelets, leukocytes).

Lub neej ntawm txhua tus ntawm cov hlwb yog heev me me thiab yog hom twg los ntawm 5 hnub (leukocytes) rau 100 hnub (erythrocytes). Qhov no entails qhov yuav tsum tau rau qhov nws tus kheej-daim ntawv rov ntxiv ntawm cov ntshav. Nyob rau hauv lub cev muaj kabmob uas cia li no muaj nuj nqi thiab ua.

Tib neeg cov ntshav-sib sau ua kabmob

Ntawm cov ntsiab lug ntawm lub cev, uas pab raws li lub tsim ntawm tshiab cov ntshav yog liab pob txha thiab tus po. Lub lymphatic system kuj yog ib tug ntawm cov chaw uas muaj hlwb pob txha yog ua hauj lwm. Qhov twg yog qhov no txoj cai thiab hais tias sawv cev rau, tham txog hauv qab no.

Qhov chaw hloov hlwb pob txha nyob rau hauv lub cev

Lub localization ntawm qhov chaw ntawm lub cev, txoj kev ua ntshav, txaus point. Lub fact tias lub ntsiab lub nruab nrog hematopoiesis - liab pob txha thiab tus po - yog tsis zoo tib yam nyob rau hauv lawv cov functionality. Yog li ntawd, nws yog hloov hlwb pob txha yog decisive thiab siv nyob rau hauv cov teeb meem no, yog li nws tseem ceeb heev rau nws qhov chaw nyob, tus xov tooj thiab lub lag luam rau tag nrho cov tib neeg lub cev.

Lub ntsiab qhov chaw ntawm pob txha localization yog cov pob txha, tab sis tsis yog txhua txhua ntawm lawv, raws li cov liab pob txha muaj xwb ib feem ntawm cov pob txha, thiab lwm yam - daj.

Cov kev loj hlob ntawm cov qauv

Tag nrho feature ntawm qhov uas muaj qhov hloov hlwb pob txha nyob rau hauv tib neeg yog raws li nram no:

1. Hloov hlwb pob txha yog pw thiab tsim los ntawm thaum pib ntawm lub embryonic tsim ntawm lub embryo.
2. Nyob rau theem embryo thiab ces ib tug me nyuam hauv plab muaj tsim, raws li zoo raws li tom qab yug tus me nyuam, nyob rau hauv ib ob peb xyoos tag nrho cov pob txha ntawm lub cev yog cov producers (manufacturers) ntawm cov ntshav thiab lymphocytes, uas yog, tag nrho cov ntaub ntawv ntawm cov liab pob txha, qhov twg lub ib thooj ntawm cov tub ntxhais undifferentiated hlwb.
3. Thaum lub sij hawm, nws yog hloov los ntawm ib tug daj, muaj raws ntawm tag nrho cov loj loj thiab me me tubular cov pob txha ntawm lub cev.

Yog li, nws yog tseeb hais tias cov pob txha hlwb pob txha muaj ob cov ntaub ntawv: liab thiab daj.

Cov yam ntxwv ntawm daj hlwb pob txha

Nws yog ib tug muaj roj zoo li tshuaj yeeb dej caw yellowish tsim hlwb ua kab lipoid cov ntaub so ntswg. Tsis yog ib feem nyob rau hauv cov ntshav tsim los yog lub tsim ntawm cellular lug tiv thaiv tsis txais. Nyob rau hauv lub chav kawm ntawm lub neej tau ntau xyoo qhov liab hlwb nyob rau hauv ntau cov pob txha, cov laus muaj hnub nyoog ua lub thawj muab tub lim diaphysis ntawm ntev pob txha. Cov yuag tag nrho cov ntsiab lus ntawm lub cev yog kwv yees li 2.5-3 kg. Qhov no yog ib nrab ntawm tag nrho cov loj ntawm lub hlwb pob txha. Lub ntsiab feature - nws yog lub hwj chim thiab muab cov pob txha elasticity. Nyob rau hauv tas li ntawd, rau cov loj kev raug mob thiab traumas daj hlwb pob txha yuav mus ib ntus hloov los ntawm ib tug liab los lub cev muaj nuj nqi ntawm cov ntshav ncig.

Tus qauv ntawm lub hlwb pob txha

Lub ntsiab tivthaiv yog ib feem ntawm ib tug loj loj ntawm undifferentiated thiab tshwj xeeb hlwb hu ua kav. Qhov no ua rau tus qauv ntawm ib cim thiab tseem ceeb heev rau tib neeg lub neej. hloov hlwb pob txha qauv muaj xws li ob tug loj cov ntaub so ntswg: reticular (stroma) thiab hematopoietic.

Cov ntaub los ntawm tag nrho cov uas tsim cov ntsiab ntawm cov internal muaj pes tsawg leeg ntawm lub liab lub hlwb, hu ua lub reticular stroma. Nws nyob rau hauv tag nrho sab hauv ntawm lub pob txha thiab muaj cov nram qab no hais:

• ib tug loj tus naj npawb ntawm cov hlab ntsha, muab nws semifluid taub hau thiab liab;
• fibroblast hlwb (producers ntawm fibrin thiab fibrinogen)
• endothelial hlwb.

Nrog rau lub reticular cov ntaub so ntswg nyob rau hauv lub hlwb pob txha muaj hematopoietic ntsiab - qia hlwb. Lawv lub sij hawm ntau yam thiab specialization daim ntawv erythrocytes, lymphocytes, platelets thiab lwm yam cov ntshav txaus thiab cov qog.

Yog li, nyob rau hauv lub cev muaj ntau ntau cov chaw ntawm cov pob txha, qhov twg lub ntsiab hematopoietic cov ntaub so ntswg - liab ntau yam ntawm lub paj hlwb teeb meem.

1. Epifazy luv luv thiab ntev cov pob txha.
2. Diaphysis ntawm tubular osteons.
3. Pav ca cov pob txha.
4. Pob txha caj qaum.

Xws li ib tug kev kho thiab localization - lub cai rau ib tug neeg laus.

Lub hlwb ntawm hlwb pob txha

Hematopoietic cov ntaub so ntswg muaj ntau ntawm qia cell muaj pes tsawg leeg thiab qauv zoo xws li cov embryonic kab. Cov no yog cov tseem ceeb heev hais, vim hais tias tag nrho cov lwm lub hlwb nyob rau hauv lub cev (thiab muaj billions) yog heev tshwj xeeb thiab muaj peev xwm tsis hloov lwm lub hlwb nyob rau hauv ib tug so ntswg los perespetsializirovatsya. Tab sis nws muaj peev xwm qia. Yog li ntawd, lawv yog lub hauv paus, uas muab sawv mus rau tag nrho cov ntshav corpuscles thiab ntawm cov lug ntawm lub lymphatic system.

Hloov hlwb pob txha hlwb tsim ib tug tsib kab mob hematopoiesis, txhua tus uas muab sawv mus rau ib tug lub caij.

1. Erythrocyte sprout ua ntshav liab - cov ntshav liab, ua tau qhov tseem ceeb functions ntawm thauj ntawm oxygen mus rau hauv nruab nrog cev thiab cov nqaij mos.
2. Granulocyte ntaub ntawv kab hlwb, eosinophils, qe thiab basophils, uas yog ib qho tseem ceeb lug kab mob tiv thaiv, thiab comprise qe ntshav dawb.
3. Lymphocytic sprout muab sawv mus rau lymphocytes - lub hauv paus ntawm lub lymphatic system.
4. Monocyte kab ntaub ntawv monocytes - tiv thaiv kab mob zoo li tus ntsiab.
5. Megakaryocytic sprout muab sawv mus rau ib tug lub neej ntawm platelets - ib qho ntawm lub ntsiab ntshav lub luag hauj lwm rau txhaws.

Yog li, lub zog ntawm pob txha yuav nyob ntawm seb namely rau lub cell qauv, nws generators. Cov no yog cov tag nrho cov tseem ceeb heev lug. Lub disappearance ntawm tsawg kawg yog ib hom ntawm cov ntsiab ua rau loj tib neeg cov kab mob uas yuav tsum tau pub dawb ntawm hlwb qia hlwb.

hloov hlwb pob txha

Qhov tshwj xeeb cov qauv thiab lub sij hawm ntawm ib tug nrog tivthaiv ntawm lub tiaj cov pob txha ua rau lawv kuj zoo kawg tseem ceeb rau tus kab mob. Nyob rau hauv no kev twb kev txuas peb yeej paub ntau yam nyob rau hauv uas lub hlwb pob txha muaj zog. Nws muaj nuj nqi raws li nram no:

1. Nws yog ib tug tas mus li khoom ntawm cov tub ntxhais, cov ntshav, uas yuav tsum tau kho tshiab txhua hnub (ntshav liab nyob li ib hnub twg, li ntawd, txhua txhua hnub, tsheej lab tuag ntawm cov lug, thiab yuav tsum tau hloov nrog tshiab).
2. Txoj kev ua ib complex ntawm lug, confronting tag nrho cov txawv teb chaws muaj teeb meem thiab lub cev raws li ib feem ntawm lub cev, xws li lub cev.
3. Tswj tus kheej cellular Cheebtsam thiab tua pliaj (e.g., mob).
4. Los ntawm limiting lub siab tshaj plaws rau lawv tus kheej puas tsuaj ntawm hlwb nyob rau hauv lub cev, uas tej zaum yuav tshwm sim los ntawm pathological dab.

Undoubtedly, cov zoo tshaj plaws yog cov kev pab cuam ntawm hlwb pob txha. Qhov twg yog lwm cov qauv uas yuav ua tau xws tseem ceeb functions? Tsis pom qhov twg. Analogues nyob rau hauv tib neeg lub cev yog tsis muaj ntau. Nws kuj tau muab kev tshwj xeeb tseem ceeb thiab uniqueness ntawm lub liab lub pob txha tib neeg lub hlwb.

po

Thaum pib peb hais tias tsis tsuas yog tus hlwb pob txha yog ib qho tseem ceeb nyob rau hauv lub tsim ntawm cov ntshav. Yog, qhov tam sim ntawd tsim ntawm ib tug loj loj ntawm nws lub hlwb thiab lub ntau yam ntawm qia hlwb yog cov yam ntxwv xwb rau nws. Txawm li cas los, muaj lwm yam hematopoietic kabmob uas pab nyob rau hauv lub hlwb pob txha muaj nuj nqi. Chief ntawm lawv - tus po. Xav txog nws cov ntsiab nta:

• Nws yog erythrocytic depot lub cev, yog tias tsim nyog (loj krovepoteri, kev poob plig, thiab lwm yam) emits ib qhov nqi ntawm cov hlwb mus rau hauv lub zuag qhia tag nrho Blutwurst loj.
• Po - ib lub khwb, lim, los ntawm kev uas cov poj mass ntawm cov ntshav. Nws neutralizes nws eliminates txawv teb chaws hais yaj tuag hlwb. Nws - ib tug indispensable nqus tsev vacuum nyob rau hauv peb lub cev.
• Cov ntaub ntawv monocytes - plawv cov ntaub so ntswg qauv.

Po nws tus kheej yog me me nyob rau hauv loj thiab nyhav txog 150 grams. Nyob saum lub plab, cia li mus rau sab laug ntawm nws.

hloov

Tu siab, lub neej muab ib tug neeg tej teeb meem, tau tshem ntawm uas tau ntev raug suav hais tias tsis yooj yim sua. Piv txwv li, ua ntej 1968 mas suav hais tias ib tug incurable cancer ntshav. Tib yam siv rau xws maladies li aplastic anemia, nqaij hlav, hlwb pob txha kab mob. Nyob rau hauv cov neeg mob, cov tshuaj tau pom tib txoj kev tawm - ib tug hloov hlwb pob txha. Tus txheej txheem yog heev cov tub ntxhais, tsis yooj yim vim tsis tiav tej yam kev soj ntsuam thiab muaj tseem tsis tau yeej ib txwm uneventful. Tab sis txhua txhua xyoo, xws hauj lwm yog ua ntau thiab simplistic nyob rau hauv tsim.

Hloov hlwb pob txha hloov yuav ua tau ntawm peb yam:

1. Tam sim ntawd cov pob txha substance.
2. Qia hlwb.
3. Qaum kua (cov ntshav).

Qhov kev xaiv ntawm hom nyob rau hauv lub hom ntawm tus kab mob. Niaj hnub no, tag nrho peb ntau ntau yam yog lug siv. Cov ntsiab teeb meem kev nyuaj siab los ntawm cov tub txawg - ib tug sau ntawm lub pub rau lub lag luam. Muaj ib tug xov tooj ntawm indicators los ntawm cov uas nws yuav tsum tau tsim rau hloov kev vam meej rau nws, thiab rau cov neeg tau kev pab.

xaiv ntawm kev hloov

Yuav kom nrhiav tau ib tug haum pub rau hloov gomeopoeticheskih lug yuav tsum yog raws li nyob rau hauv ob peb yam kev mob:

• txuam ntshav pab pawg neeg (tsis yeej ib txwm tseem ceeb, tab sis tseem ceeb heev);
• tsis muaj tib neeg hnyav los yog mob cov kab mob, thiab kis kab mob;
• tsis muaj uas pub kev puas hlwb kev ntshawv siab thiab roj ntsha kab mob.

Feem ntau cov feem ntau zoo heev sib tw rau pub dawb yog haiv neeg: viv ncaus, cov kwv tij, cov me nyuam los yog cov niam txiv. Tab sis nyob rau hauv cov ntaub ntawv no, cov ntaub so ntswg compatibility guaranteed tsuas cai nyob rau hauv 25 feem pua ntawm cov neeg mob. Nws yog nyuaj heev los txiav txim seb lub zoo tagnrho qhov chaw, uas yuav muab ib tug noj qab nyob zoo pob txha (cov yees duab ntawm yuav ua li cas nws zoo nkaus li, koj yuav saib tau nyob rau hauv tsab xov xwm). Yog li ntawd nws yog tsim nyog los saib rau hloov cov neeg. Xws li tus neeg yuav ua tau tus neeg sawv cev ntawm tag nrho cov haiv neeg, haiv neeg thiab lub teb chaws.

Hom ntawm pob txha tsim muaj kev sib hloov

Muaj ob lub ntsiab hom:

• autologous hloov - thaum qia hlwb yog npaum li cas los ntawm tus neeg mob nyob rau hauv ua ntej thiab tub nyob rau hauv tej yam kev mob ua ntej phais;
• allogeneic hloov - cov khoom yog coj los ntawm cov pub, uas yog tag nrho cov haum rau cov tej yam kev mob ntawm cov neeg, nrog rau cov txheeb ze.

Raws li tam sim no cov ntaub ntawv paus ntawm lub ntiaj teb no coj noj coj ua nyob rau hauv lub pub yog muab nyob rau hauv lub teb chaws Yelemees thiab lub tebchaws United States. Nyob rau hauv Russia, heev ob peb hloov, yog li peb cov neeg mob transplanted qia hlwb ntawm lwm haiv neeg.
