[Measurement of the specific electrical resistance of the blood (rho) and its determination mathematically in dogs].

The role of specific electric resistance of blood (rho) in determining systolic cardiac volume by impedance plethysmography is discussed. It is pointed out that the known five mathematical equations for rho estimation by the hematocrit (Hct) and the temperature (T0) differ from one another and are moreover good for humans, but not for experimental animals. A suitable equipment and technique for direct (in vitro) measurement of rho is suggested.

[Normal hemostatic indices in experimental animals].

On the basis of the studies conducted by the authors on 19 nonbred dogs and 25 rabbits of the strain Cincilla and Belgium giant the normal values of the basis indices of hemostasis were determined: thromboelastography (r+k and ma), amount of fibrinogen, number of thrombocytes, thromoboplastic time, time of recalcification. The obtained data are shown on a table. The obtained data could serve as orienting data in examining hemostasis in dogs and rabbits under various experimental conditions and models for investigating various human pathology.
