Abstract : Morpho-physiological indices were investigated of blood and external respiration of Muridae, leading burrow and semi-burrow mode of life. The respiration was registered on the electrocardiograph band synchronously with electrocardiogram. Blood test was carried out by the usual methods. It was established that frequency of rodent respiration is in a reverse dependence on the weight of animal body and if the weight is equal the greater volume of pulmonary ventillation is observed in more mobile species. In burrow rodents the abundance of carbon dioxide in inspirated air (1.0-1.2%) causes only slight raring and deepending of respiratory movements. In semi-aquatic rodents the raring and deepening of respiration follows the diving. In the animals under study the tendency is observed to decrease the erythrocytes in blood with an increase of body weight. In burrow and semi-aquatic rodents the high concentration of haemoglobin in erythrocytes is observed. Maintenance of semi-aquatic rodents (coupies) without access to water for 3-4 years leads to the decrease of haemoglobin concentration up to 12.8-13.3 g% (as compared with 13.9-16.0 g%). In more active Muridae the concentration of haemoglobin is higher than in less active ones. (Author)
