[A comparative analysis of the oxygen-binding and antioxidant properties of the blood of laboratory animals and the muskrat Ondatra zibethica]. / Sravnitel'nyi analiz kislorodsviazyvaiushchikh i antioksidantnykh svoistv krovi laboratornykh zhivotnykh i ondatry Ondatra zibethica.

Close correlation of oxygen-binding properties of haemoglobin and the content of malonyl dialdehyde (MDA) in animal blood plasma was shown. The higher the affinity of haemoglobin to O2, the lower MDA level in the blood plasma. For the muskrat Ondatra zibethica, representing diving animals, MDA content is lower and catalase activity is higher compared with the laboratory rat.

[Physicochemical and functional properties of hemoglobin of mice infected with Ehrlich's carcinoma]. / Fiziko-khimicheskie i funktsional'nye svoistva gemoglobina myshei, zarazhennykh kartsinomoi Erlikha.

Injection of white mice with Ehrlich's carcinoma triggers an increase in the mice blood erythrocyte fraction suspended in the 14% sucrose concentration zone. As established by acid erythrograms, a quantitative increase of this red blood cell population is due to an increased rate of erythroblast maturation and occurrence of immature cell forms in the blood stream. As shown by alkali denaturation of hemoglobin, tumour development causes an increase in alkali-resistant hemoglobin fraction in the erythrocytes. On the basis of the data on alkali denaturation of hemoglobin, it is suggested that in the infected mice increased rate of erythrocyte maturation go in line with selective binding of alkali resistant hemoglobin fraction to red cell membrane.
