title: 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.
abstract: 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.
