The in vivo inhibition and recovery of acetylcholinesterase in the thoracic ganglionic mass of the freshwater rice field crab (Oziotelphusa senex senex) during and after exposure to sumithion.
The freshwater crab (Oziotelphusa senex senex) showed a dose-dependent inhibition of thoracic ganglionic mass acetylcholinesterase (AChE) activity during 48 h of exposure to 1, 2 and 4 ppm of sumithion. A progressive recovery of AChE activity from sumithion-induced inhibition was observed in this tissue within 15 days after transferring the crab to toxicant-free clean water.
