Effect of chlorophyllin bait on acetylcholinesterase and cytochrome oxidase activities in the nervous tissue of Lymnaea acuminata with exposure of sunlight and red light

This study has focused on the effect of chlorophyll in bait on acetylcholinesterase and cytochrome oxidase activities in the nervous tissue of Lymnaea acuminata with exposure of sunlight and red light. Treatment with 24 h LC 50 chlorophyllin (40% and 80%) at sunlight and red light exposure in infected and uninfected snails lasted for 24 h caused strong inhibition in the activities of acetylcholinesteras e and cytochrome oxidase with a dose-dependent manner. The maximum inhibition of AChE (54.91% of control) and cytochrome oxidase (55.54% of control) were observed in the nervous tissue of infected snail exposed to 80% of the 24 h LC 50 values of chlorophyllin + red light. Amongst the al l spectral band of light a greater inhibition of cytochrome oxidase and AChE activity was observed with the red light + chlorophyllin treated snails in infected/uninfected L. acuminata. Present study confirmed the toxic effect of chlorophyllin + red light against snails.
