Changes in catecholamine content (CA) in hypothalamus of male and female eel (Anguilla anguilla L.) were defined using the Falck-Hillarp histochemical fluorescence method for a 24-hr period during the summer (L:D = 16:8) and winter (L:D = 8:16). 2. A circadian rhythm in the catecholamine content was found in the hypothalamus. CA content was lower by night than by day. 3. A longer light day (summer period) caused the shifting of rhythm phase in CA content. 4. Sex of eels does not affect CA content in the hypothalamus.

采用福尔克-希拉尔普组织化学荧光法，测定了夏季（光照:黑暗=16:8）和冬季（光照:黑暗=8:16）期间，雄性和雌性欧洲鳗鲡（Anguilla anguilla L.）下丘脑儿茶酚胺含量（CA）在24小时内的变化。2. 在下丘脑中发现了儿茶酚胺含量的昼夜节律。夜间CA含量低于白天。3. 较长的光照日（夏季）导致CA含量的节律相位发生变化。4. 鳗鲡的性别不影响下丘脑的CA含量。
