摘要：

In this study, the involvement of nitric oxide (NO) in the mechanism of anxiety was investigated. The rats: received an intraamygdaline or intrahippocampal injection of the nitric oxide synthase inhibitor, N-G-nitro-1-arginine (L-NOARG), and were then tested in the plus-maze test. L-NOARG induced a decrease in the time spent by rats in the open arms. Conversely, the administration of the melanin-concentrating hormone (MCH) into these structures increased the number of entries into the open arms as well as the time spent on them. MCH injected in rats pretreated with L-NOARG also was able to revert the anxiogenic effects of L-NOARG in amygdala. (C) 2001 Elsevier Science Inc. All rights reserved.
