摘要：

N-Acetyltransferase activity was measured in organ-cultured chick pineal glands. A circadian rhythm ofenzyme activity persisted in cultured glands for up to 4 days. The phase of the rhythm in vitro closely approximates its phase in vivo. These observations demonstrate that the pineal gland of chicks contains (or is) a self-sustained circadian oscillator.
