Method of repeated determination of muscle heat resistance in individual frog specimens

, : Method of repeated determination of muscle heat resistance in individual frog specimens. Tsitologiia 19(8): 927-930

The heat resistance of m. interphalangialis of fingers of hind extremities of Rana temporaria L. has been determined. No significant differences were observed in the average values of the heat resistance in fingers 3 and 5 isolated simultaneously. In separate individuals there exists a high positive correlation between the heat resistance levels of these muscles. When the muscles are isolated successively rather than simultaneously, the correlation degree depends on the time lapse between their isolation from the organism. With 1-14 days lapse the correlation breaks down, to be restored after a longer interval. Taking this into account, a method of successive isolation of m. interphalangialis can be used when studying the dynamics of muscle resistance within the same organism.
