An evaluation of the elevated plus-maze test using the novel anxiolytic buspirone

Previous work suggests that the elevated plusmaze test of anxiety is insensitive to the anxiolytic effects of the novel anxiolytic buspirone, which shows an anxiogenic-like profile in this test. This paper examines some of the possible reasons for this and the role that buspirone's agonist activity at 5-HT_1A receptors plays in this effect. A variety of 5-HT_1A receptor agonists (p-aminophenylethylm-trifluromethylphenyl piperazine, (+)- and (-)-MDL 72832) showed similar activity to buspirone, as did the related compound ipsapirone. (-)-MDL 72832 was more potent than (+)-MDL 72832, in keeping with its stereoselective action at 5-HT_1A receptors. The ₂-adrenoceptor antagonist properties of 1-pyrimidinyl piperazine, a metabolite of buspirone, did not appear to be relevant to this action of buspirone as neither it nor idazoxan showed an anxiogenic-like profile. Neither chronic treatment with buspirone (1 mg/kg SC twice a day for 16 days) nor depletion of 5-HT withp-chlorophenylalanine changed the anxiogenic-like activity of buspirone in the elevated plus-maze test. These results suggest that an agonist action at postsynaptic 5-HT_1A receptors mediates the anxiogenic-like effects of buspirone in the elevated plus-maze test and that this test may either be insensitive to certain classes of anxiolytics or is measuring something unrelated to human anxiety states.

情绪智力与大学生焦虑、抑郁和心境的关系研究

自Ｇｏｌｅｍａｎ《情绪智力》[1] 一书出版以来 ,情绪智力一词已为很多人所熟悉。情绪智力一般被定义为个体适应性地知觉、理解、调节和利用自己及他人的情绪的能力[2 - 3] 。虽然情绪智力有时被当作能力(或智力 )看待[2 ,4 ] ,有时则被认为是个性特质[5- 8] ,但研究者都相信情绪智力对于个体在现实生活中取得成功起着十分重要的作用[1] 。关于情绪智力常见的一个命题是个体情绪智力越高越能体会到情绪上的幸福感 (Ｅｍｏｔｉｏｎａｌｗｅｌｌ -ｂｅｉｎｇ) [1- 2 ] 。为了回答这个问题 ,本研究拟探讨情绪智力与大学生焦虑、抑郁和心境的关…

CONSISTENCY OF PERFORMANCE CHANGE AND AUTONOMIC RESPONSE AS A FUNCTION OF EXPRESSED ATTITUDE TOWARD A SPECIFIC STRESS SITUATION

A persistent problem in stress research has been that some individuals may show impairment, while others show improvement or no change in performance under stress. Attempts to relate this variance in performance to general anxiety or other personality variables have generally not been too successful. Based upon responses to a fear of shock item in an attitude questionnaire, Ss were classified as “high fear of shock” or “low fear of shock” types. Half of the Ss in each group were assigned a perceptual-motor task; the others were assigned a cognitive-interference task. After training, all Ss were informed that they would be required to maintain their training performance levels in a situation in which they would be shocked if performance declined. Performance and heart rate measures taken during training were compared with the same measures taken under the threat-of-shock conditions. Results indicate significant differences between groups in both performance and physiological activity with “high fear of shock”Ss exhibiting relatively greater performance impairment and increased heart rate.

Anxiety Profiles of Mice Selectively Bred for Intermale Aggression

In the present study we compared genetically selected aggressive (TA) and nonaggressive (TNA) male mice, as well as males from an unselected control line (SW), in three tests of anxiety: the elevated plus-maze, the light-dark box, and the staircase test. Males were tested repeatedly for 3 days. In all three tests TA males were found to be more active and less anxious than TNA males, with SW males showing more or less intermediate scores. Furthermore, repeated plus-maze testing induced anxiety-like behavior in both TA and TNA mice, whereas repeated testing in the light-dark and staircase paradigms resulted in different responses. Whereas TNA animals were found to be stable, TA animals showed habituation on the second and third day of testing. The obtained data support the conclusion that a higher-level offensive aggression entails lower level of anxiety.
