Effect of cold stress and starvation on the cerebral glucose-6-phosphate dehydrogenase activity of male garden lizards of three different age groups.
In the present study we observed that the cerebral glucose-6-phosphate dehydrogenase activity of male garden lizards did not change appreciably during maturation but showed a significant rise between middle-aged and old-aged groups. Whereas cold stress (1 h at 0-4 degrees C) induced a significant increase in G6PDH activity of young animals, it caused a decrease in both middle-aged and old lizards. This decrease was more severe in the old group than in the middle-aged group. Another form of stress, 72 hours of starvation, led to a significant increase in enzyme activity in young and in middle-aged lizards with young animals showing the greater effect. The old counter-parts showed a decrease in enzyme activity after starvation stress.
