Reticulocytes ndizvo zvinowanzoitika

Erythrocytes inokonzera kukwirira kwe okisijeni muropa uye chiyero che hemoglobin. Apo nhamba ye erythrocytes inodonha zvakanyanyisa, reticulocytes inowedzera kubudiswa mumapfupa emapfupa. Aya masero mumazuva mashomanana anova masero matsvuku eropa akazara uye anokwanisa kukwana zvizere kukanganisa kwakasimuka. Chii chinowanzoitwa reticulocytes, uye chii chinogona kuchinja muhuwandu hwavo hunoreva, tichakurukura nhasi.

Chii chinowanzoitwa reticulocytes muropa?

Zvinyorwa zve reticulocytes muropa zvinogona kusiyana nekuda kwezvikonzero zvakawanda. Muzvinyorwa, zvinosanganisira zvirongwa zvehutachiona hunobatanidza neropa kurasikirwa nekudzvinyirira kwetsvo uye mapfupa emapfupa. Ichokwadi ndechokuti kushandurwa kwe reticulocytes mu erythrocytes kunoitika pasi pesimba re erythropoietin, hormone inogadzirwa neadrenals neitsvo. Muitiro we reticulocyte unotsanangurwa mu ppm maererano nehuwandu hweropa uye pakati pezvimwe zvinhu zvinogona kuratidza kukwana kwehomoni iyi. Kuwedzera kwe erythropoietin kunoratidza oksijeni nzara, zvikonzero zvechiitiko ichi zvakasiyana:

• kukurumidza kuparadzwa kwe erythrocyte semugumisiro wemakemikari kurwisa kubva kunze;
• kuparadzwa kwe erythrocytes nekuda kwemakemikari mabasa ehupenyu;
• kurashikirwa kwezvizhinji zveropa;
• kupumha kuora mwoyo;
• kuputika, kana kuvharwa kwemasimba makuru.

Chimiro che reticulocytes muvakadzi nevarume chinowanzosiyana. Nguva isati yasvika, vakomana nevanasikana vari mumatambudziko akaenzana, asi mukuita basa rekuberekwa, vakadzi vanorasikirwa nehuwandu hwemwedzi, uye munzvimbo iyo uye masero matsvuku eropa, saka reticulocyte inotarisa kuchinja zvikuru. Saka, pano ndiyo tsika ye reticulocytes muzana yezvizvarwa zvakasiyana-siyana zvevarwere:

• Vana vacheche vachangoberekwa - 0.15-1.5%;
• 2-6 vhiki yeupenyu - 0.45-2.1;
• 8-12 vhiki yeupenyu - 0,25-0,9%;
• 6 mwedzi - 1.5 makore - 0.2-1%;
• 1,5 -2 makore - 0,2-0,7%;
• kubva pamakore maviri kusvika kumatanhatu - 0.2-0.8%;
• kubva pamakore 6 kusvika ku13 - 0.2-1.3%;
• vasikana vanopfuura makore gumi nemaviri uye vakuru - 0.12-2.05%;
• vakomana vanopfuura makore gumi nemaviri nevarume - 0,24-1,7%.

Kana nhamba ye reuculocytes yakajairika, iyi haisi chivimbo chokuti muviri une utano, chete kuongororwa kwepuropa yeropa kunogona kusimbisa kusavapo kwehutachiona. Sarudza hutano hwe reticulocyte neropa rakatorwa kubva mumutsipa. Vana vaduku zvikuru vanogona kushandisa capillary ropa nokuda kwechinangwa ichi.

Ndezvipi zvingava kutsauka kwe reticulocytes kubva pachimiro mukuongorora ropa?

Kana kuongororwa kweropa kunoratidza kuti reticulocytes iri pasi pemazuva ose, izvi zvinogona kuratidza kuchinja kwakadaro mumabasa omutumbi:

• marudzi ose ezvirwere zvepfungwa;
• kukanganisa kumapfupa emapfupa;
• kuderera kwezvikamu semugumisiro we erythropoiesis unogara nekusingaperi (kuparadzwa kwe erythrocytes uye kudiwa kwekuvandudzwa kwavo);
• aplastic anemia ;
• hypoplastic anemia;
• kupera kwemafupa anemia;
• ropa uye zvirwere zvehemopoietic;
• zvirwere zvepachikafu ne metastasis mune zvivako zvefupa;
• chisingaperi chinodhakwa.

Nhamba yakakwirira ye reticulocytes inoratidza kuti paiva nekuderera kukuru kwehuwandu hwemasero matsvuku eropa uye muviri wakaita mairi zvakakwana - nekuwedzera nhamba yemasero kubva mairi erythrocytes matsva anoumbwa. Hezvino zvikonzero zvinowanzoitika zvezvikamu zve reticulocytes kumusoro kwechimiro:

• kubudirira kwe-anti-anemia therapy;
• nguva ichangobva kubuda ropa;
• kuparadzwa kukuru kwe erythrocyte;
• malariya ;
• Thalassemia nedzimwe zvirwere zvinopararira zvinokonzera hemoglobin uye erythrocytes;
• zvirwere zvepachikafu nemapfupa emarara.

Iyo chaiyo inokonzera kuchinja mumwero we reticulocyte inogona kusimbiswa nekunyatsoongorora nhoroondo yose.
