Abstract：
:During the re-entrainment of the rat pineal N-acetyltransferase (NAT) rhythm to an 8-h advance of a light-dark (LD) cycle accomplished by shortening of one dark period, the advanced light period phase-delayed the evening NAT rise and phase-advanced the morning decline. The phase-relationship between the rise and the decline became so compressed that after the second and the third light period the NAT rhythm was not expressed even in constant darkness and reappeared only within another cycle at the time of the original night. Only after the fourth advanced light period, the NAT rhythm phase-jumped into the advanced night.

BRAIN RESEARCH文献大全abstract：:Repeated administration of high doses of methamphetamine produced long-term decreases in dopamine (DA) levels and in the number of DA uptake sites in the rat striatum. These two effects were dose-related and did not appear to be due to the continued presence of drug in striatal tissue. Long-lasting depletions induced ...
