摘要：

24 h of in vivo exposure to 40 and 80 % LC50 of the synthetic pyrethroid cypermethrin significantly reduced the acetylcholinesterase, cytochrome oxidase and lactic dehydrogenase activity in the nervous tissue of L. acuminata. Succinic dehydrogenase activity increased significantly after the same treatment. Fifteen minutes in vitro exposure to different doses of cypermethrin also significantly inhibited cytochrome oxidase and lactic dehydrogenase activity. However, acetylcholinesterase and succinic dehydrogenase activities remain unaltered. It is concluded that the cypermethrin on the one hand causes repititive discharges at the nerve terminal and on the other hand blocks the electron transport chain.
