Ntshav Puas Txaus - ib tug ntshav teeb meem

Ntshav Puas Txaus - ib tug mob uas yog yus muaj los ntawm ua hauj lwm ntawm cov ntshav, ib tug txo nyob rau hauv lub concentration ntawm hemoglobin protein thiab cov ntshav liab ib chav tsev ntim ntawm cov ntshav. Txij li thaum lub ntsiab muaj nuj nqi ntawm erythrocytes yog thauj nrog rau oxygen hauv lub cev, lawv pathology (cov tsos ntawm tsis paub qab hau cov ntshav liab, tsis ntau ntawm cov ntshav liab nyob rau hauv tus kab mob, lub xub ntiag ntawm hlwb nrog genetic tsis xws luag) ua rau txoj kev loj hlob ntawm hypoxia.

Cov kev loj hlob ntawm anemia tej zaum yuav txuam nrog ib tug ntau yam ntawm yam (muaj ntau hom ntawm tus kab mob thiab toxicity, hlwb hypoplasia, hemolysis, hemorrhage, thiab cov zoo li). Ntshav Puas Txaus - ib tug kab mob nrog los ntawm ib tug ua txhaum ntawm lub pa muaj nuj nqi ntawm cov ntshav. Thaum hnyav anemia tshwm sim mob hnyav oxygen tshaj uas tej zaum yuav ua rau tuag. Nws yuav tsum tau hais tias tus kab mob no yog yus muaj los ntawm tsis tsuas ib tug txo nyob rau hauv lub concentration ntawm hemoglobin thiab cov ntshav liab, yog li kuj hloov ntshav Science News for KIDS profile.

Lub keeb kwm ntawm tus kab mob anemia yog txuam nrog rau cov Nrab Hnub nyoog. Nyob rau hauv cov hnub, cov neeg mob ranked li vampires vim hais tias boednosti. Cov neeg mob yuav hais kom koj haus dej haus tsiaj txhu cov ntshav, nws muab ib tug ib ntus zoo ntxim. Cov ancient Greeks pom tias cov xeb dej yuav pab nyob rau hauv cov kev kho mob ntawm anemia. Nyob rau hauv lub xyoo pua 16th, Paracelsus rau cov kev kho mob ntawm tus kab mob uas siv cov hlau oxide. Nyob rau hauv thaum ntxov 20th xyoo pua los kho cov neeg mob uas anemia ntse pib siv nyoos siab, raws li cov kws tshawb fawb tau pom tias nws yog nyob rau hauv cov tsiaj cov khoom muaj lub siab tshaj plaws nqi ntawm hlau muaj rau lub cev.

kev faib ntawm anemia

Cov kev faib yog raws li pathogenetic hauv paus ntsiab lus. Muab pathogenesis, posthemorrhagic anemia yog txwv kom muab zais rau hauv (tshwm sim vim ntshav poob), hypoplastic (kaw nrog neeg pluag kev), hemolytic (tsim raws li ib tug tshwm sim uas muaj zog hemolysis los yog krovorazrusheniya).

Etiology thiab pathogenesis

Noj haus anemia - ib tug kab mob uas tsim thaum lub sis tshaj nyob rau hauv khoom noj khoom haus cov khoom los yog raws li ib tug tshwm sim ntawm assimilation los ntawm lub cev ntawm tshuaj uas kom tej hauj lwm ntawm hematopoiesis. Tej yam muaj xws li cov protein, hlau, tooj liab, cobalt, cov vitamins B1, B12, Sun, ascorbic acid. Txij li thaum cov neeg haus ib tug tseem ceeb npaum li cas ntawm cov khoom ntawm tsiaj keeb kwm, nyob rau hauv kev xyaum, kev noj haus anemia yog tsis tshua muaj. Ho feem ntau yuav muaj lub cim ntawm ib theem anemia, uas muaj vim malabsorption ntawm minerals los yog vitamins. Nyob ntawm seb yuav ua li cas cov tebchaw yog absorbed rau hauv lub cev, lub anemia yog txwv kom muab zais rau hauv B12, folic acid thiab hlau tsis muaj peev xwm.

B12-deficiency anemia, thiab folic acid - ib tug pathology uas tsim vim ib tug tsis ntawm cobalt nyob rau hauv khoom noj khoom haus, vitamin B12, Sun, C, gastritis, Gastroenteritis, thiab muaj roj gepatoze. Secondary kuj tsim anemia nyob rau hauv mob mob (tuberculosis), invasions, hypo- thiab beriberi.

Nrog ib shortage ntawm cobalt nyob rau hauv khoom noj khoom haus yog tsis txaus cov hnyuv microflora synthesizes cyanocobalamin, thaum B12, hnub thiab C yog tsim nyog rau ib txwm ntau yam ntawm erythrocytes. Cyanocobalamin (Vitamin B12) absorbed los ntawm lub cev tsuas yog thaum nws ua num ua ke nrog ib tug nrog antianemic tau - gastromukoproteinom, sinteziruyuyuschimsya plab. Raws li ib tug ntawm xws li kev sis raug zoo yog tsim nyob rau hauv lub raum tshiab antianemic tshuaj - erythropoietin, uas nkag mus rau hauv cov hlab ntsha thiab ua ke nrog ascorbic acid yuav tsum tau vitamin Bc nyob rau hauv active daim ntawv - tetrahydrofolic acid uas yog lub luag hauj lwm rau tej kev erythropoiesis. Antianemic yam tsis muaj peev xwm yuav tsim raws li ib tug tshwm sim ntawm cov kab mob ntawm lub plab, qhov twg lub siab tawg tag gastromukoproteina synthesis, Nyob rau hauv cov ntaub ntawv no, cyanocobalamin los ntawm cov zaub mov uas tsis siv rau cov synthesis ntawm erythropoietin. Tsis txaus synthesis ntawm erythropoietin kuj yuav tsim nyog tau kev raum kab mob.

Thaum tsis muaj peev xwm ntawm vitamin B12 thiab lub hnub muaj infringements ntawm lub cev txheej txheem ntawm maturation ntawm lub hlwb ntawm hlwb pob txha.
