MYELOGRAMS OF MARSH (PELOPHYLAX RIDIBUNDUS) AND POOL FROGS (PELOPHYLAX LESSONAE) (AMPHIBIA: RANIDAE) OF CONVENTIONALLY “BACKGROUND” AND ANTHROPOGENOUSLY TRANSFORMED TERRITORIES IN THE NIZHNIY NOVGOROD REGION

Authors: Romanova E. B., Shapovalova K. V., Mar’in I. A.

Our comparative analysis of the myelograms of these lake and pond frogs has revealed a higher erythropoietic activity of the bone marrow in the conditionally "background" amphibians (group 1) as compared to the individuals from urbanized (group 2) territories. Restructuring of the bone marrow cellular composition and activation of the myeloid cells were the adaptive reaction of the amphibians to living in polluted conditions of their aquatic environment. The response variability of particular myelopoiesis elements reflected the plasticity of the organism’s compensatory abilities.

BLOOD SYSTEM OF VOLES UNDER (CRICETIDAE, RODENTIA) INDUSTRIAL POLLUTION

Authors: Tarakhtii E. A., Mukhacheva S. V.

A complex of the blood system characteristics and the concentrations of heavy metals (Cu, Zn, Cd, and Pb) in the liver of bank voles (Cl. glareolus) and red voles (Cl. rutilus) from background and industrial polluted areas were studied. Heavy metals were found to affect the structure of erythrocytes, the blood cell composition and concentration in the hematopoietic organs. The revealed differences between the blood system's responses of bank and red voles to pollution conditions are due to different levels of the pollutant accumulation in the body.
