Short term effect of thiamethoxam on glutamate dehydrogenase (GDH) activity in Snake head, Ophiocephalus punctatus
Abstract
An organochloride, thiamothoxam is used commercially for controlling the agricultural pest. In the present study it was observed that at sub-lethal concentration (29.483 ppm) the GDH activity in the liver, kidney, gill and muscle of Ophiocephalus punctatus increased non-significantly from 24hrs to 96hrs of exposure. The maximum activity in all these organs was at 96 hrs. It has been concluded that thiamethoxam at sub-lethal concentration may alter the glutamate metabolism in all the tissues by enhancing the GDH activity in short duration of exposure
