摘要：

Preliminary ultrastructural studies on the effects of 5,6-dihydroxytryptamine (5,6-DHT) on the anterior byssus retractor muscle (ABRM) of M. edulis showed degeneration of 2 types of monoaminergic nerves after 10 days of drug treatment. One type contained large granular vesicles (560-1680 .ANG.) while the other had small granular vesicles (200-640 .ANG.). These axons possibly represent serotonergic and dopaminergic nerves, thought to innervate this muscle. Two other types of profiles seemed unaffected by the drug. One conformed to cholinergic nerves while the other had a predominance of large opaque vesicles (1200-2500 .ANG.). The significance of these findings is discussed in the light of recent observations on the neurotoxic effects of 5,6-DHT on vertebrate and molluscan nerves.
