Erythropoiesis asymmetry in cats

Abstract

Asymmetry is considered to be the common-biological law. It is realized at all known life organizational levels beginning from the molecular (protheins, aminoacids, DNA, mediators, enzymes asymmetry), cellular, organ (first of all - brain hemispheres, then lungs, skeletal muscles, kidneys, salivary glands, neuro-endocrine organs, and others) to organismic (Protozoas, Nematodas, Reptiles, Amphibias, Mammals, Human Being, some flowers et al.) one. But there are little data dealing with blood asymmetry (immunity, leucocyte particularly neutrophils, intact and activated platelets). Erythrocytes acquire the ability to have their asymmetrical shape during erythropoiesis. This phenomenon is tightly regulated by different substances (ATP, calcium, magnesium, hydrogen protons etc.). It has been proved erythrocyte membranes biochemical asymmetry existence. One can find little facts about velocity sedimentation rate, hemoglobin concentration, blood group agglutinogenes asymmetry. There exist some data about coagulational and tissular hemostasis asymmetry.
