Unugyada dhiigga cas: diidmada caadiga ah iyo suurto gal

Dhiigga, iyo sidoo kale wax kasta oo unug ka kooban unugyada iyo fulinta ay shiid walax intercellular. ratio The iyaga ka mid ah waa in ay tahay mid slurry sameeyay a xubno (cells) ee dhexdhexaad ah ee dareeraha ah.

formation gacanta ku dhacaa dhuuxa lafta sprouts casaan iyo caddaan, ka dibna by sinusoids badan waxay galaan dhiigga, halkaas oo ay ku qabtaan hawlo takhasus sare leh ay. Laakiin ka hor in, ay mari kaladuwan multi-stage of total unugyada progenitor unugyada asliga pluripotent ah inuu weynaado unugyada: leukopenia, dhiig xinjirowga sameeya iyo unugyada dhiigga cas, heerka unugyada kuwaas oo is beddelid karaa sida muujin ka timid magdhow ama cudurada. Ugu danbeysay ee ka mid ah kuwan waa conveyors aasaasiga ah ee ogsijiin, halka haray dhiiga cad (leucocytes, waxay ka kooban tahay 5 fasalada) iyo unugyada saxan (platelets) waxay u qaadeen reactions difaaca wajiyo badan. Tusaale ahaan, limfosaytis siiyaan difaac, neutrophils, iyo monocytes - phagocytosis iyo proteolysis, iyo eizonofily bazo- - dheecaan ah ee walxaha bayoloji firfircoon: histamine, thromboxanes, prostaglandins iyo leukotrienes, PAF, qayb vasoconstriction iyo dardargelinta unugyada kale. Xinjiraha sameeyaan nooc ka mid ah "fur" haddii ay dhacdo oo burbur derbiga vascular.

Unugyada dhiigga cas, heerka of: qaab-dhismeedka iyo shaqada

Unugyada dhiigga cas ka mid ah unugyada ugu takhasusay yihiin. dhallinyarada ah waxaa loo yaqaan barametereka of reticulocytes inta lagu guda jiro unugyada koriinkedu ay si tartiib ah u lumiyaan yaruna oo badalay leh hemoglobin - dhismeedka quaternary protein awood u sameynta xiriir daciif ah ogsijiin, waa ay fududahay in ay la wareegaan in qalintaanka pulmonary, iyo sidoo kale ay fududahay in la siiyo in unugyo ka. Unugyada dhiigga cas sida caadiga ah waxay leeyihiin qaab biconcave, maxaa yeelay waxa ay bixisaa qaar ka mid ah faa'iidooyinka by sii kordhaya aagga dusha sare inay xidhxidhaan oxygen dheeraad ah iyo jidaynayey "qaab" sida uu maraa weelashii yar-heerkiisa ah microvasculature ah. Maxaa yeelay, dadka oo arsaaqa tamar badan iyo sidaas oxygen, fiirsashada weyn oo ay dhiigga iyo unugyada dhiigga cas yihiin.

caadi ah loogu tala galay dumarka waa 3.9 - 4.7 * 10 ^ 12 / L ragga, heerka la mid ah waa 4.0-5.0 x 10 12 / L. Waxa kale oo uu sharaxayaa heerka antiandrogen sare, uu saameyn ku dhiirrigelin on erythropoiesis. qayb kale oo muhiim ah KLA waa unugga maxaa yeelay, at-fiirsashada hoose halkii mugga dhiigga unit baxdo xaalad bahal "anaemia", Ulasocto hypoxia iyo ischemia xubnaha kordhaya. tilmaame Color muujinayaa inta hemoglobin cokan unugyada dhiigga cas. caadi The of this index waa loo siman yahay si 0.8-1.05 unugyada, iyo marka ay dhaco, waxaad la hadli kartaa oo ku saabsan dhiig hypochromic. Sidoo kale dhiig normochromic waxaa laga yaabaa in sidii markii hemolysis xad-dhaaf ah marka burburinta sare ee unugyada la kulmin heerka erythrocytes oo la hayo ay Avv dheelitirka LSP failure dhaca beerka iyo caajisnimo 90-110 maalmood ka dib. anemia Hyperchromic arkay in loogu yeero anemia megaloblastic, faa'iideysashada deficiency ah vitamin B12 ama folate-H4, qayb ka ugu muhiimsan ee erythropoiesis.
