Reticulocyte - ndi chiyani ichi? Reticulocytes: ponseponse

Reticulocyte - ndi achinyamata mawonekedwe maselo ofiira magazi asanayambe awo. A magazi thanzi la munthu lili kuchokera 0.2 kuti 1.2% ya maselo amenewa. Izi zili reticulocytes wachibale erythrocytes lapansi. Okalamba nthawi ya pakati pa 4 ndi 5 masiku.

Reticulocyte - ndi chiyani ichi?

Mbali khalidwe la mitundu achinyamata pamaso pa erythrocytes mu cytoplasm granular filamentous chinthu chomwe chimayimira aggregated mitochondria ndi ribosomes. mankhwala ndi wapezeka ndi njira yapadera ya kudetsa smears magazi. Mtundu uwu wotchedwa reticulocytes supravital, mwachitsanzo Linapangidwa sitinadzere mwa chisanadze fixation maselo.

reticulocyte gulu

Pali magulu asanu a reticulocytes. Iwo amasiyana ndi reticular reticulum. The mauna wandiweyani, ndi reticulocyte wamng'ono.

The reticulocyte wamng'ono - selo kukhala ndi mauna mu mawonekedwe a tangle wandiweyani. maselo amenewa ali reticulocyte 1 gulu. reticulocytes More okhwima amaoneka ngati thunthu mu mawonekedwe a mitsempha kuoneka bwino kangaude. Ndipo magulu 4-5 zikuoneka mu mawonekedwe a filaments munthu ndi granules. Kawirikawiri anthu athanzi magazi kufunga reticulocytes 4 ndi 5 gulu, mwachitsanzo wokhwima maganizo. Iwo amapanga 80% reticulocytes. Koma ndi pathologies ena, pamene kusinthika umalimba, pali ponso reticulocytes magulu 1-3, i.e., mitundu wamng'ono. Tingaone zimenezi mu pathologies zotsatirazi:

• Pankhani ya vuto pamene retikulotsitarnogo B12-chofunika anemias.
• Hemolytic magazi m'thupi ndi Al.
• Erythroleukemia.

Ntchito ya reticulocytes

Reticulocytes ndi ntchito zofanana erythrocytes, monga zoyendera mpweya zimakhala zosiyanasiyana ndi ziwalo, koma dzuwa la ndondomeko imeneyi anali penapake poyerekeza erythrocytes okhwima. Reticulocytes angathe adsorbing mamolekyulu yachitsulo ali hemoglobin chifukwa transferrin zolandilira.

Pamene magazi akutengedwa pa reticulocytes?

Tiyerekeze mayeso magazi. Reticulocytes - ndichiyani? Kodi kusanthula iwo anazindikira ndi aliyense? zitsanzo zosankhidwazi magazi pa chizindikiro zimenezi pa kusanthula ambiri. Ngati ndi kotheka, dokotala wasankha nkhani amasonyeza mu dera limene muyenera kusankha zina reticulocyte kuwerengedwa.

maphunziro apadera, kusanthula izi sikutanthauza, koma anaganiza m'mawa pa chopanda kanthu m'mimba. kusanthula izi zikhoza kutheka nthawi iliyonse, ngati n'koyenera. Magazi wachotsedwa chala, kufufuza ikuchitika mu dipatimenti ya zasayansi hematology.

Reticulocyte achiyesa Ndisonyezeni supravital papezeka kuipitsa mbiri njira tosaoneka ndi maso, i.e. ndi kuwerenga nambala zawo pansi simungathe kutiona. Mu Laboratories ano, pali hardware reticulocyte ochuluka njira chibwenzi.

Kodi kupereka magazi reticulocytes? Kodi izo ndi pamene kusanthula zimenezi umayendetsedwa? Mafunso amenewa ayankhidwa. Tsopano tiyeni tikambirane za mfundo zachilendo kwa chizindikiro ichi.

Reticulocytes. Chikhazikitso mu kufufuza

ndi zimene mlingo wa maselo ofiira mu magazi zotumphukira? Kugonana kusiyana mfundo phindu zaka pokhapokha 11-12 pamene kuwerengetsa zosonyezera monga reticulocytes magazi. Ponseponse ana pansi m'badwo uno chimodzimodzi. Pambuyo atsikana amayamba kusamba zonse, kusamba magazi imfa kumachititsa kuwonjezeka osiyanasiyana maselo erythroid oscillations.

Werengani reticulocyte ponseponse mu magazi zotumphukira akhoza kukhala mu tebulo pansipa.

Kodi kuwonjezeka reticulocytes?

Makamaka kwambiri ndi quantification wa reticulocytes mu anemias. Choyenera kuchita zimene kuchuluka reticulocytes, wotchedwa reticulocytosis. Kuwonjezeka maselo amenewa, limodzi ndi kuwonjezeka mu milingo hemoglobin, kusonyeza wabwino regenerative mphamvu m'mafupa. Makamaka, kuchuluka reticulocytes ndi pathologies zotsatirazi:

• Hemolytic magazi m'thupi (matenda omwe Mulungu anawanenanso chiwonongeko cha erythrocytes - hemolysis) - reticulocytes akhoza kukhala pamwamba 60%. Makamaka ukuwonjezeka yogwira chigawo mavuto hemolytic.
• Mmene thupi hemotoxin limene hemolysis amapezeka. Iyi ndi ululu wa njoka ya mphiri kapena mankhwala amagwiritsidwa ntchito pofuna kuchiza eritremii. Poizoni mu malungo kuyambitsa hemolysis.
• Pachimake posthemorrhagic magazi m'thupi (pambuyo ataya magazi). Retikulotsitarny mavuto zambiri kumachitika masiku 3-4 pambuyo kutaya magazi. Nthawi zina limasonyeza magazi chobisika, monga m'mimba chilonda kapena tayifodi ndipo ena.
• Polycythemia.
• Malungo.
• Nthawi kuchira pambuyo mankhwala amphamvu kapena cheza mankhwala.
• mafupa metastases.
• Chotero boma kumachitika mu akusowa pachimake oxygen.
• Zotsatirazi poika njira ya vitamini B12 pa matenda a B12-akusowa magazi m'thupi.
• Pa kulandira medicament "Erythropoietin" amene amagwiritsidwa ntchito pofuna kuchiza kuchepa kwa magazi m'thupi.
• Pambuyo ntchito yaitali ena odana inflammatories ndi antipyretics.
• Pambuyo ntchito ya "L-dopa" Parkinsonism.
• Kusuta fodya.

Reticulocytosis kusiyanitsa zoona ndi zonama.

Woona ndi wabodza reticulocytosis

Koona reticulocytosis kuchuluka kwa achinyamata maselo ofiira kugwirizana ndi chiwerengero kuchuluka kwa iwo m'mafupa. Izo zimasonyeza ndondomeko ya erythropoiesis, ie, mapangidwe woona maselo a magazi.

Pamene onyenga reticulocytosis reticulocytes kuchuluka kokha magazi zotumphukira ndi mafupa, chiwerengero chawo utachepa kapena anakhalabe yachibadwa. Zimenezi zikusonyeza leaching iwo mu m'magazi ku m'mafupa. A zoterezi zidzachitika njira yotupa kapena chotupa mu m'mafupa, monga metastases.

Kodi kuchepetsa reticulocytes?

Chiwerengero cha reticulocytes amachepetsa ngati chopinga wa erythropoiesis. Izi angayambe pathologies monga:

• Aplastic magazi m'thupi (a moyo pachiswe mmene wodwalayo).
• B12-akusowa magazi m'thupi.
• Iron akusowa magazi m'thupi.
• Pakumwa folic acid akusowa magazi m'thupi.
• Sediroblastnaya magazi m'thupi.
• Thalassemia.
• njira Neoplastic ndi mafupa.
• matenda a chithokomiro ntchito (kuchepetsa ntchito), monga myxedema.
• impso matenda aakulu, omwe mwina chifukwa cha kuchepa kwa erythropoiesis.
• Aakulu uchidakwa, imbaenda ku matenda aakulu a chiwindi ndi impso.
• matenda aakulu.
• Pamene uremia - boma kulephera aimpso, amene akukhala chifukwa cha magazi mkulu wa zinthu nitrogenous.
• Pa phwando la mankhwala ena, monga "Carbamazepine" kapena "Chloramphenicol" ndi Propafenone sulfonamides.

Ife tinapeza chimene chimapanga ngati khungu la magazi monga reticulocyte a. achinyamata awa ndi maselo ofiira, kumene zina akufotokozera wathunthu maselo ofiira a magazi, amene amapereka zimakhala onse ndi ziwalo za thupi ndi oxygen.
