摘要：
1. 1. N-acetyltransferase was present in pineal glands of 14-day-old chick embryos though no rhythm either in LL, DD or LD 12:12 was observed in this age. 2. 2. Daily rhythm in pineal NAT activity was found in 18-day-old embryos incubated under LD 12:12 and LD 16:8 but no NAT rhythm was detected in DD or LL. 3. 3. NAT rhythm persists for 2 days in constant darkness and it may be eircadian in nature. 4. 4. Presence of melatonin (85 ± 8 pg/mg tissue) was detected in pineals of 18-day-old chick embryos. © 1990.
