Two species of poikilothermic vertebrates, a teleost fish (Channa punctatus) and the garden lizard (Calotes versicolor) were used to study the effect of age on brain catalase (CT) activity and its inhibition by manganese (II) chloride (MnCl(2)). While in fish the CT activity of brain remained unchanged throughout the lifespan, the enzyme activity decreased during maturation and then showed an increase during aging in the garden lizard. MnCl(2) at a concentration of 333 muM in incubating medium… CONTINUE READING
