...B.S. Jena; B.K. Patnaik The degree of inhibition of hepatic succinic dehydrogenase activity by malonate, a competitive inhibitor, did not differ between young and middle-aged lizards. On the other hand, the same parameter increased significantly between middle-aged and old lizards. The percent...

...B.S. Jena; M.K. Mohanty; B.K. Patnaik A comparison between middle-aged and old lizards revealed no significant age change in glucose-6-phosphate dehydrogenase activity of liver and kidney. Thermal inactivation at 51 ± 1°C induced a significantly higher degree of decline in enzyme activity...

...B.S. Jena; B.K. Patnaik Catalase activity in liver and kidneys of male garden lizards remained unchanged during maturation, but showed an increase during ageing. Instead of inactivating catalase, thermal treatment at 60 ± 1 ° C caused a marginal increase in enzyme activity in the liver of middle...

...B.S. Jena; B.K. Patnaik The hepatic glucose uptake of male garden lizards did not change during maturation but showed a decline between middle-aged and old age groups. The decline in glucose uptake following starvation and cold stress was age-dependent, the young and middle-aged lizards being more...

... a spectrophotometric method. Results: At a final concentration of 666 µ M , the metal ion inhibited the enzyme activity of the brain in both species. In fish brain the degree of inhibition was not age-dependent. On the other hand, the rate of inhibition increased between young and middle-aged lizards followed...
