MCV (he koko ho'āʻo): transcript. MCV: kūmau

Helu i ka helu o ka erythrocyte keena, e hoʻoholo lākou awelika ka leo a me ke koko Ka Ikepili i loko o ka huipūʻana me nā haʻawina e hoʻohana no ka palena pauʻike, o kekahi mau ano o ka anaemia, a 'ē aʻe pathological ana.

He aha ka ka ula koko keena

E like me nā 'ano o nā erythrocytes (ʻulaʻula koko aeee), a mea hoomaikai hana kūikawā ole-nukelea keena, ke koko biconcave kinona, he mea hiki, e hoʻoponopono i ka moku'āina o ke ola ana o ke kanaka. Ke erythrocyte aeee i kakauiaʻi maluna naehana pigment - hao-i loaʻa ka kumuʻiʻo hemoglobin. O ka papa kuhikuhi hana o kaʻulaʻula koko keena halihali oxygen, i mea nui no ka functioning o nā mea a pau nā loko i loko o ke kino. I loko o ke kahua o kēia mau keena hoʻopili like i ka ula iwi lolo. Kēia kaʻina ua hauma¯na ma erythropoietin, a ua hua mai i ka nui buke hakuʻala keena ma lalo o hypoxic ana.

Normal hoʻololi kemikala o hemoglobin a me kaʻulaʻula koko aeea ho okumu mea hiki wale nō i loko o ke alo o ka cyanocobalamin, a me ka folicʻakika e like me ka nui kūpono lako o ka hao Ion. Ma ka systemic holo erythrocytes nei ma kahi o 4 mahina. A laila, he mea no ka make ana o ke koko keena, e he wahi no lākou hoʻololi iho ka spleen a me reticuloendothelial kahua.

He aha ke ano o ia ke ano o MCV?

MCV erythrocyte inideka mea he 'inideka e characterizes i ka waiwai o ka awelika ka leo o ka ula koko keena. I mea e hookupaa nui ae i ka pololeiʻike, no ka maʻi i nā mea maʻi, kauka mau koi 'ia ke koko helu. Deciphering MCV olelo nei koko keena ma ka kanaka kino kulana. I ola kanaka, o ka lākiō o kaʻulaʻula koko aeee i ka huina koko ka leo mea mau, a nolaila, e ole e hoʻololi i ko lakou nui, a me ka helu.

Ma ka hooulu ana o allergies, li nui, hiki ke loaʻa ma ka hele i ke koko MCV-Ka Ikepili ka nele o nā wikamina a me ka mea pōhaku waiwai. Deciphering i nā hualoaʻa e hoike ana i abnormalities, hoike o ka hiki pathological Hawaii.

Kēia 'inideka ua ho'ākāka' ia i loko o ka mau lapaʻau Ka Ikepili o ke koko, a ma ka kaʻawale mahele.

Pehea e hoʻomaulia i ka MCV

No ka ho omaulia i ka awelika ka leo o ka ula koko aeea mea pono e mahele i ka nui o ka halepaahao ka leo ma ka huina helu o ka erythrocyte koko keena. Kekahi hana no ka helu ana hematocrit ma muli o ka mahele helu 'ole' inideka i 1 mm o ³ o ke koko ma ka helu o ka ula koko keena. Ma lalo o ka mea kaulana hematocrit pakeneka hiʻohiʻona ma waena o ka buke o ke koko keena a me ka huina koko ka leo.

Ma MCV koko Ka Ikepili, ho omńkalakala i ka i pili i ka auhau ana o ka nui o kaʻulaʻula koko keena, ua noʻonoʻo emi pololei ma mua o nā kiʻina hana'ē aʻeʻelua o ka ho omaulia. O ke kumu ho i ka mea i ka wā i ke anawaena o ka erythrocyte keena ma ka 5% o kona leo ua hoʻololi e 15%. I ka pono o keia anakahi i ke nānaina ka wā he nui helu oʻulaʻula koko aeee i i loli shape. No kekahi laʻana, ina e alakai i ka piha koko helu, MCV waiwai mea maʻamau inā ua loaʻa ke hoomanawanui i loko o nā macro- a me ka microcytosis.

It E e kaʻikaʻiʻia ma ka manaʻo i microspherocytes anawaena ua nui undervalued, akā, ma ka like ana o ka awelika ka leo i loko o ka maʻamau huahelu, i mea kumu ka mea, ua mau pono haukaʻe i microscopy o ke koko ia.

pa alima o ke ana

Ke pa alima o ana o ia hoʻi, ke corpuscular ka leo (MCV) ia femtolitry (HI) ole cubic micrometers (microns ^3).

He aha ke ano o ke Ka Ikepili?

Me keia koko aiao diagnose acee? Iuo oeiia o ka anaemia e noi ana kekahi kanaka.

MCV hualoaʻa o ke koko Ka Ikepili e leie aku e maopopo ma waena o:

• ka wā hoemiia hoʻololi kemikala o ka polypeptide lei microcytic anaemia, hao deficiency a me ka thalassemia Ion, hapa o ka 'ole o ka hemoglobin;
• normochromic normocytic anaemia paha i hoʻomōhala ana i ka maʻi maʻi, me ka iniiaiie iwi lolo ole, ma muli o ka hoemiia? iecaianoaaiiuo o ka erythropoietin;
• macrocytic anaemia me ka deficiency o folicʻakika a me ka cyanocobalamin ka wā māhuahua erythrocyte nui.

No kēlā me kēia moku'āina nele kona mau kanaka. No kaʻike, ka mea nui lapaʻau koko Ka Ikepili, ho omńkalakala i MCV (makemake corpuscular ka leo) e leie aku oe e hoohewa aku i ka moku'āina oʻulaʻula koko keena.

Inā keia anakahi i ka maʻamau waiwai, ua kapaia normocytic ka ula koko keena. I lalo i nā hualoaʻa MCV Index o aeee koko i kapaia o microcytic, a ma inflated aiee o ko lākou manaoio macrocytic.

Kau aʻe 'ana o ka wai-electrolyte koena i loko o ke kino hele' ana o ke koko MCV-Ka Ikepili, ho omńkalakala i hana i Hōʻike he loli i loko o ka paakai kaulike. Inā ka awelike ka leo o kaʻulaʻula koko keena emi o maʻamau, he mea hiki ke kamailio e pili ana i ka nele o ka loli o ke kanaka kino. No ka laʻana, ma ka dehydration hypertonic ano o MCV i loko o ke koko hoʻokolohua i kuʻu iho. Inā ke anakahi ma luna o ke kūmau, laila mākou i ke kamailio e pili ana i dehydration hypotonic.

Ma Ka Ikepili o MCV hiki ke 'ole e likeʻole aʻe. Hoemi i ka awelike erythrocyte ka leo e i hemolysis ai ÿole mechanical kaʻina hana i loko o ke alakaʻi i kaʻapu kōheoheo i huiʻia. Low koko MCV-Ka Ikepili, ho omńkalakala i Hōʻike ka hoʻomanawanui ka alcoholism a me ka hoʻohana 'ana o ka metanola like me kaʻawahia waiwai, mea hoi i uncommon.

Norma MCV

Mean corpuscular ka leo anakahi hilinaʻi nui ma luna o ke ahonui o ka makahiki, ka mea i hāʻawi mai i ke koko ho'āʻo MCV. Kūmau i loko o kēlā mau makahiki pae e e kū hoʻokahi, a me ka mea, ua olelo ia i loko o femtolitrah. Standards i huahelu o aiee o keia 'inideka, i mea ma ka laulā o ka mai 80 a hiki i 100 femtolitrov makua nā mea maʻi.

Ma na hihia a pau ia mea mea nui MCV-koko hoʻokolohua transcript. Norma ua i ka lani kiekie loa, i loko o nā pēpē. Ka mea e ole oi 140 femtolitrov. E like me ke keiki ulu ka maʻamau aiee o keia 'inideka i hoemiia. Penei, o ka uku no ka makahiki-kahiko kamaiki makemake ia i ka laulā o ka mai 71 a hiki i 84 femtolitrov. Mai 1 ka makahiki, a i ka elima makahiki o ka makahiki i ka waiwai o ka awelika ka leo o kaʻulaʻula koko keena kaulua mai ka 73 a hiki i 85 femtolitrov. E hoʻomaka ana mai ka 5 a hiki i 10 makahiki ua manaoia e ia i ka hopena o ka maʻamau MCV Ka Ikepili mai ka 75 a hiki i 87 femtolitrov, a me wale i ka adulthood, keia anakahi i makua kūmau.

Underreporting MCV

Inā ka waiwai o MCV i loko o ke koko ho'āʻo aʻela, ia Hōʻike ka hooulu ana o microcytic anaemia. ? Ac? Aaioea ia me ka shortage o ka hao Ion i loko o ke koko wai koko, ke alo aku o kekahi maʻi ano maʻi a me ka hereditary maʻi, i ka ulu ana o ka malignant hikoko, ke alakaʻi i kaʻapu kōheoheo i huiʻia e lawe i kekahi mau lapaʻauʻia, ka waiʻona hainā, ma ka thalassemia me ua hoʻemi hoʻololi kemikala o ka polypeptide kaula, hapa o ka 'ole o ka hemoglobin.

Inflated cia MCV

Ke kiekie aiee o ka awelika ka leo o ka erythrocyte keena hōʻike i ka hooulu ana o macrocytic anaemia, a 'ē pathological rula e i wehewehe aku e:

• deficiency o ka wikamina B ₁₂ (cyanocobalamin) ma ka 'aʻe absorbability;
• folievodefitsitnoy anaemia me folicʻakika shortage;
• megaloblastic anaemia ma muli o ka 'aʻe o ka DNA hoʻololi kemikala;
• pernicious anemia;
• hypothyroidism, ma a he mea he nele o ka thyroid hōmona;
• intestinal maʻi;
• ake maʻi;
• hoemiia hana o pancreatic keena;
• maʻi o ka iwi ka lolo;
• kaʻapu kōheoheo aʻawahia ka lapaʻauʻia;
• alcoholism.

Anakahi MCV koko Ka Ikepili paha e iki kiʻekiʻe ma mua o maʻamau i loko o na wahine, i ka wa e lawe hormonal contraceptives. Uahi paka e uwahi ana hiki no hoi i ka hua ma ka awelika buke o ka ula koko keena.

Ka manaʻo o MCH

Together me ka wehewehena o MCV, MCH-koko Ka Ikepili e leie aku e hana i ka palena pauʻike, e hooholo i ka ano o ka anemia. Ka mea, 'o ia hoʻi ka huahelu e like me ka awelika o kekahi erythrocyte hao-i loaʻa ka hemoglobin kumuʻiʻo. Ana i ka loa hua'ōlelo.

E huli i ke kaulana waiwai o ka hemoglobin maʻiʻo ma kekahi erythrocyte ma ka māheleʻana i ka hemoglobin lehulehu ma ka helu o ke erythrocyte keena. I e like me ke ano anakahi, MCH-Ka Ikepili e leie aku iā mākou i ka nui pololei hooholo i ka nui o ka hao-i loaʻa ka kumuʻiʻo i ka ula koko keena.

Ua haawiia i ke kumukuai o keia 'inideka mea kaʻawale anaemia hyper-, hypo a me normochromic. Normohromiyu hiki ke loaʻa i loko o ola kanaka, akā, i kekahi manawa, ia accompanies hemolytic a me ka anaemia aplastic, e like me na kumu pili me ka huʻi ke koko me keia poho.

I ka hypochromia i emi erythrocyte ka leo, i hoakaka ia haawiia microcytosis a emi ma ka hemoglobin kumuʻiʻo me kaʻulaʻula koko keena me ka maʻamau ka leo. Penei hypochromia hiki pu ana me erythrocytes me ka hoemi nui, a me ka normo- a me macrocytes.

Hyperchromicity hoike ana ia lŘlŘ nānā 'ole o ka saturation o hemoglobin kumuʻiʻo erythrocyte keena, a kena ae la puke wale o ka ula koko keena. O ke kumu ho i ka mea ana i hoomahuahua ma ka hemoglobin ma luna o ka physiological kūmau o kona crystallization a me ka hemolysis.
