Title

Effect of Nitric Oxide on Basolateral Amygdala on Persistence of Anxiety and Depression in Stressed Male Rats

Pages

  13-22

Abstract

 Introduction: The current study aimed at investigating the role of Nitric Oxide (NO) in the maintenance of Anxiety and Depression induced by Stress in male Wistar rats using intra-Basolateral Amygdala (BLA) injection of NO precursor, L-Arginine, Nitric Oxide Synthase (NOS) inhibitor, and L-NAME. Methods: Two 23-gauge stainless steel cannulas were placed in the BLA, stereotaxically. Seven days later, animals experienced electro foot shock Stress based on the following protocol: animals experienced four sessions of Stress for 60 minutes in four consecutive days. Five minutes before each Stress session, the animals received different doses of L-Arginine or L-NAME (1, 5 and, 10 μ g/rat) or saline (0. 5 μ L/rat) intra-BLA. Six days after the Stress termination, animals were tested for maintenance of Anxiety-like behavior (elevated plus maze; EPM) and eight days after the Stress they were examined for Depression (forced swimming test; FST). Results: Stress reduced the time and number of open arms and decreased motor activity on EPM. Stress-induced Anxiety was inhibited by L-Arginine and L-NAME (1, 5, and 10 μ g/ rat). L-Arginine and L-NAME induced Anxiety in non-Stressed rats. Stress also increased the immobility time in animals in FST paradigm. Interestingly, both L-Arginine and L-NAME, in all doses reduced the Stress effect. Conclusion: BLA Nitric Oxide may play a pivotal role in Anxiety and Depression induced by Stress in rats. Since the effects of both L-Arginine and L-NAME were similar, NO might have a modulatory role in the BLA.
