title: Deltamethrin induced changes in choline transport and phosphorylation activities in synaptosomes from the optic lobe of squid, Loligo pealei.
abstract: 1. Deltamethrin, a powerful synthetic pyrethroid causes a significant change in choline transport in freshly prepared synaptosomes from squid optic lobes. 2. At resting state (nondepolarized) such an effect manifested as a reduction of 14C-choline uptake in a short term (1 min) uptake experiment. 3. At depolarized state, or under conditions where synaptosomes are subjected to osmotic, aging and other stress conditions, deltamethrin caused stimulation of 14C-choline uptake, resulting in elevation of the levels of total radiocarbons in synaptosomes. 4. Such changes are accompanied with changes in overall phosphorylation activities in synaptosomes.
