Abstract

It was found that pimozide, haloperidol and alpha-methyl-p-tyrosine (alpha-MT), drugs inhibiting central catecholaminergic (CA) transmission, increased the development of morphine dependence measured as wet dog shakes in rats. Reserpine inhibiting CA and serotoninergic (5-HT) transmission, decreased the development of morphine dependence in rats. The inhibitory effect of reserpine was reversed by 5-hydroxytryptophan (5-HTP), but not by L-dihydroxyphenylalanine (L-DOPA). These results suggest that wet dog shakes might develop as a result of regulatory adaptation in the 5-HT neurotransmitter system.

摘要

研究发现,匹莫齐特、氟哌啶醇和α-甲基对酪氨酸(α-MT)这些抑制中枢儿茶酚胺能(CA)传递的药物,会增加以大鼠湿狗样抖动来衡量的吗啡依赖性的发展。利血平抑制CA和5-羟色胺能(5-HT)传递,会降低大鼠吗啡依赖性的发展。5-羟色氨酸(5-HTP)可逆转利血平的抑制作用,但左旋多巴(L-DOPA)则不能。这些结果表明,湿狗样抖动可能是5-HT神经递质系统调节适应的结果。
