title: Seasonal changes in the activity of rhodanese in frog (Rana temporaria) liver.
abstract: 1. The investigators studied annual changes in rhodanese activity in mitochondria and cytosol of frog liver cells (Rana temporaria) and found that the value of the enzyme-specific activity was higher in mitochondria than in cytosol, showing significant seasonal fluctuations. 2. The character of changes in the rhodanese activity in mitochondria, regardless of the sex of the studied animal, was demonstrated to be dependent upon the seasonal changes in frog thyroid gland function. 3. In the supernatant fraction of R. temporaria liver homogenate, seasonal changes of rhodanese specific activity seemed to be related to changes in hepatic function.
