Abstract

Adrenergic and cholinergic receptors have been studied in isolated skin melanophores of a catfish Clarias batrachus. Catecholamines induced a strong aggregatory effect on the melanophores. Melanosome aggregation induced by adrenaline and noradrenaline was partially blocked by alpha adrenergic receptor blockers and a beta receptor blocker. Cholinomimetic drugs aroused a significant dispersion of melanophroes. Atropine effectively blocked the dispersal, responses of melanophores to acetylcholine and carbachol, while, hexamethonium blocked the nocotine induced dispersal responses of the melanophores.

摘要

对鲶鱼（胡子鲶）离体皮肤黑素细胞中的肾上腺素能和胆碱能受体进行了研究。儿茶酚胺对黑素细胞有强烈的聚集作用。肾上腺素和去甲肾上腺素诱导的黑素体聚集被α肾上腺素能受体阻滞剂和β受体阻滞剂部分阻断。拟胆碱药物引起黑素细胞显著分散。阿托品有效阻断了黑素细胞对乙酰胆碱和卡巴胆碱的分散反应，而六甲铵阻断了烟碱诱导的黑素细胞分散反应。
