Nerve cells in a culture from chicken embryo brain were used to study the allyl chloride-induced effects on the contents of intracellular Ca2+, Ca2+-free CaM, cAMP and the activity of Ca2+/CaM-PK II. The results showed that with the increase in the concentration of allyl chloride there was a significant increase in the content of Ca2+and cAMP, and the activity of Ca2+/CaM-PK II in the cells (P<0.01), but a marked decease in Ca2+-free CaM (P<0.01). The results suggest that the neurotoxicity of allyl chloride might be related to the increase in intra-cellular Ca2+ and the activation of CaM and Ca2+/CaM-PK II, eventually leading to the accumulation of degenerative MT in the nerve axon.
