Circadian rhythm and neural regulation of rat pineal angiotensin converting enzyme
Angiotensin converting enzyme was detectable in rat pineal gland and exhibited a circadian rhythm in activity with maximum at the end of the light phase of daily photoperiod. Superior cervical ganglionectomy (SCGx) or exposure to light for 6 days increased enzyme activity and obliterated morning-eve...
