... unexplored. Material and Methods: In the present study, we investigated anxiety- and panic attack-like behaviours in a predator (cat)-prey confrontation paradigm and compared them with those in classical assays, such as the elevated plus-maze (EPM), marble-burying, and open field tests (OFTs), using C57BL/6J...

... reported such a decreased variability in panic disorder patients. In this study, we report on HR variability in 12 depressed and 6 panic disorder patients at baseline and 1 and 3 weeks of treatment with imipramine as measured by the standard deviation, mean consecutive difference and the standard deviation...

...Vikram K. Yeragani; Robert Pohl; Richard Baton; C. Ramesh; Paula Weinberg Jitteriness appears to be a specific side effect of tricyclic antidepressant treatment in panic disorder patients.

...Sharon Pellow; Sandra E. File The β-carboline FG 7142 and pentylenetetrazole, believed to act at different sites on the GABA-benzodiazepine receptor complex, have anxiogenic activity in the social interaction test in the rat. Two compounds that have anti-panic activity in man, the tricyclic...

...Sandra E. File; Amanda L. Johnston The ability of chronic treatment with imipramine (an antidepressant with anti-panic activity) to antagonise the anxiogenic effects of 3 different compounds was investigated in the elevated plus-maze. The compounds chosen are likely to produce anxiety by activity...

... variability and sympathetic function. Methods: We examined the effects of β-adrenergic stimulation on R and T amplitude variability in panic disorder patients by infusing the β-adrenergic agonist isoproterenol in 6 panic disorder patients and 11 normal subjects. The ECG signal was analyzed before the infusion...

The birth dates of psychiatric patients were compared to those of the general Tuscane and Italian populations. The monthly distribution of birth...
