Reticulocyte - yintoni na le nto? Reticulocytes: yamihla

Reticulocyte - yinto iiseli abaselula igazi ifomu elibomvu ezihlangwini zabo. A igazi labantu esempilweni iqulathe ukusuka 0.2 ukuya 1.2% yezi seli. Oku okuqulethwe reticulocytes kuthelekiswa le erythrocytes. Ngokwaluphala ixesha eliphakathi-4 ukuya kwezi-5 iintsuku.

Reticulocyte - yintoni na le nto?

Eyona uphawu iifom abaselula ubukho erythrocytes kwi icytoplasm kweziyobisi filamentous granular emele ezilinganisweni mitochondria kunye ribosomes. Le into ibanjiwe yi indlela ekhethekileyo smears amabala igazi. Lo mbala ngokuba reticulocytes supravital, ie Yenziwe ngaphandle kokudlula kwi pre-nitrogen kweeseli.

iqela reticulocyte

Kukho amaqela ezintlanu reticulocytes na. Ahluke kwi reticulum reticular. Umnatha shinyi, reticulocyte omnci.

Le reticulocyte omncinane - iseli kokuba umnatha kwi ngokohlobo tangle ashinyeneyo. iiseli ezinjalo iqela reticulocyte 1. reticulocytes Okuninzi aqolileyo kuvela into ngokohlobo spider emithanjeni ibonakale ngokucacileyo. Kunye namaqela 4-5 elivela ngohlobo kwayo ngamnye kunye granules. Ngokuqhelekileyo abantu igazi esempilweni koyisa reticulocytes-4 no-5 iqela, ie kakhulu oqolileyo. Benza up 80% of reticulocytes. Kodwa ezimbi ezithile, xa ngokutsha luyomelezwa, kukho ukwanda reticulocytes amaqela 1-3, ngamanye amazwi, Iifom abaselula. Oku kubonakala ezimbi zilandelayo:

• Kwimeko sentlekele xa retikulotsitarnogo anemias B12-awukho.
• igazi Hemolytic and al.
• Erythroleukemia.

nemisebenzi reticulocytes

Reticulocytes babe umsebenzi ofanayo ukuya erythrocytes, njengoko izithuthi oxygen izicwili ezahlukeneyo kunye amalungu, kodwa ukusebenza kwale nkqubo engaphantsi ngandlel kunokuba erythrocytes abaqolileyo. Reticulocytes ayakwazi adsorbing iimolekyuli yentsimbi equlathwe ngehemoglobin ngenxa receptor transferrin.

Njengoko igazi kuthathwa kwi reticulocytes?

Masithi ndaphumelela uvavanyo lwegazi. Reticulocytes - ntoni na? Ngaba uhlalutyo abayibona nayo nayiphi na? Blood isampuli kwesi salathisi ezenziwe ngexesha uhlalutyo jikelele. Ukuba kuyimfuneko, ugqirha liqeshe analyses kubonise xa ufuna ukwenza reticulocyte count.

uqeqesho olulodwa, olu cazululo akafuni kufuna, kodwa ndagqiba ekubeni ulithathe ngalo kusasa ungatyanga. Olu hlahlelo ingenziwa nangaliphi na ixesha, ukuba kuyimfuneko. Yegazi iyathathwa ngomnwe, uphando kwaye wenziwe kwisebe yelebhu Haematology.

Reticulocyte count ukuvelisa i supravital anegazi smear indlela kakhulu, ngamanye ngokubala inani labo phantsi ngemicroscope. Kwiilebhu mihla, kukho iintsimbi iindlela ukubala reticulocyte ukuza kuthi ga ngoku.

Indlela ukuba unikele ngegazi ukuze reticulocytes? Yintoni na nalapho azihlole okulawulwa? Le mibuzo iyaphendulwa. Ngoku makhe sithethe amaxabiso eqhelekileyo kuyo ngesi salathisi.

Reticulocytes. Isikhundla kwi cazululo

Yintoni ireyithi iiseli ezibomvu zegazi egazini peripheral? umahluko Sex kwemilinganiselo uxabiseke kwiminyaka kuphela emva 11-12 xa kubalwa i index njengoko reticulocytes ngegazi. Ummiselo kubantwana abangaphantsi kwesi sigaba iyafana. Emva amantombazane aqala esexesheni rhoqo, ukulahleka igazi sexesheni kukhokelela uluhlu ukwanda erythroid iiseli oscillations.

Funda norm reticulocyte egazini peripheral banokuba kule theyibhile ingezantsi.

Ntoni ukwanda reticulocytes?

Eyona ibalulekileyo quantification of reticulocytes ku anemias. A imeko banda apho reticulocytes, ekuthiwa reticulocytosis. Ukwanda kwezi seli, sikhatshwe ukwanda kumanqanaba ihemoglobin, ebonisa indlela elungileyo amandla okungenisa wamathambo. Ngokukodwa, ukwanda reticulocytes ezi ezimbi zilandelayo:

• igazi Hemolytic (izifo ebandakanya ukutshatyalaliswa erythrocytes - hemolysis) - reticulocytes ingaba ngentla-60%. Ingakumbi ukunyuka Icandelo esebenzayo iingxaki hemolytic.
• Iziphumo hemotoxin emzimbeni apho hemolysis kwenzeka. Oku kunokuba irhamba ityhefu okanye amachiza asetyenziswa ukunyanga eritremii. Ubuthi seengcongconi zingenza hemolysis.
• igazi Acute posthemorrhagic (emva abophe kakhulu). nengxaki Retikulotsitarny ngokuqhelekileyo kwenzeka iintsuku 3-4 emva ukulahleka igazi. Ngamanye amaxesha lityhila ukopha efihlakeleyo, ezifana isilonda esiswini okanye esifo fever kunye nabanye.
• Polycythemia.
• Malaria.
• Le sokubuyisa ixesha ekuphulukenwe emva ichemotherapy okanye radiation therapy.
• metastases wamathambo.
• Loo urhulumente kungenzeka acute oxygen intswelo.
• Emva kokutyunjwa kwikhondo vitamin B12 apha ukunyanga B12-intswelo anemia.
• Emva kokufumana le medicament "erythropoietin" esetyenziselwa ukunyanga anemia.
• Emva ukusetyenziswa elide anti-ukudumba ezithile kunye antipyretics.
• Emva kokuba isicelo i "L-dopa" Parkinsonism.
• Xa abatshayayo.

Reticulocytosis yokwahlukanisa lokwenyaniso nolobuxoki.

reticulocytosis lokwenyaniso nolobuxoki

Xa reticulocytosis ukwanda lokwenyaniso abatsha iiseli ezibomvu ezinxulumene inani elandileyo kwabo umongo wethambo. Ibonisa inkqubo erythropoiesis, ie, ukuyilwa yokwenene iiseli ezibomvu zegazi.

Xa reticulocytes reticulocytosis lobuxoki banda kuphela egazini neuropathy lomongo wethambo, inani bancipha okanye bahlala eziqhelekileyo. Oku kubonisa ukuhluzeka kuloko ke yangena egazini ukusuka umongo wethambo. A inkqubo efanayo kwenzeka ngexesha iinkqubo ukudumba okanye ithumba kwi umongo, ezifana metastases.

Ntoni ukuncitshiswa reticulocytes?

Inani reticulocytes kunciphisa njengoko inhibition of erythropoiesis. Oku kwenzeka ezimbi ezifana:

• igazi Aplastic (a kwimeko yomguli ezisongela ubomi).
• B12-intswelo anemia.
• Ayoni anemia.
• Folic acid intswelo anemia.
• Sediroblastnaya igazi.
• Thalassemia.
• iinkqubo Neoplastic umongo wethambo.
• ukuphazamiseka thyroid operation (function unciphiso), ezifana myxedema.
• isifo sezintso ezimandundu, leyo isenokuba ngenxa ukuhla erythropoiesis.
• utywala kakhulu, nto leyo ekhokelela ukuba izifo kwesibindi kunye nezintso.
• izifo ezondeleyo.
• Xa uremia - imo ukusilela kwezintso, nto leyo iba unobangela igazi ophezulu kwezinto nitrogen.
• Ifika iziyobisi ezithile, ezifana "Carbamazepine" okanye "Chloramphenicol" kunye sulfonamides Propafenone.

Siye safumanisa into eyenza iseli igazi efana reticulocyte. Ezi seli abatsha ezibomvu, ukusuka apho liphuhlisa ngakumbi iseli olupheleleyo igazi elibomvu, obubonelela ngako konke ancedisana amalungu omzimba mpilo.
