Sublethal effect of mercury and lead on monoamine oxidase in different regions of the brain in three freshwater teleosts.
Effect of mercury and lead at 24 and 48 h was investigated on monoamine oxidase (MAO) activity in different regions of the brain (telencephalon, cerebellum, diencephalon and medulla oblongata) in Labeo rohita, Ham., Clarias batrachus, L. and Channa punctatus, Bloch. Highest rise in MAO activity was recorded in telencephalon with mercury followed by lead. Maximum variations in the level of MAO activity in different regions of the brain were recorded at 24 h exposure. The observed alterations were discussed in relation to different parameters.
