The purpose of the first experiment was to investigate whether diazepam could acquire anxiogenic properties by signalling an aversive event. Rats were trained in an operant chamber in the pentylenetetrazol (PTZ) model of anxiety. Thereafter the animals were divided into groups that received classical diazepam conditioning (Group 1), and conditioning of diazepam + tone (Group 2). In the test phase diazepam was injected prior to placement in the operant chamber. Group 2 selected the PTZ-appropriate lever more often than the other groups, indicating that the tone induced anxiety, and diazepam did not. Tones and shock may therefore be more easily associated than diazepam and shock. The second experiment investigated this. Rats were trained the same way as in the first experiment. Thereafter the experimental group received injections of a small dose of diazepam prior to a second injection of a large dose of diazepam. The hypothesis was that a compensatory anxiogenic conditional response to diazepam's anxiolytic effect should be elicited by the small dose. There were no differences between the groups in lever selection, indicating that a compensatory anxiogenic response was not elicited. 相似文献

In Norway, legalized gambling is pervasive, easily accessible and socially accepted, particularly the participation in national lotteries. We conducted a stratified probability sample study during January–March 2007 (age group 16–74 years, N = 3,482, response rate 36.1%) to assess gambling behavior and prevalence of problematic gambling by the NORC Diagnostic Screen (NODS). Overall, 67.9% of the study population had been engaged in past-year gambling and 0.7% were past-year problematic gamblers (NODS score 3+). Male gender, low educational level, single marital status, and being born in a non-Western country were variables positively associated with problematic gambling. Past-year problematic gamblers indicated the slot machine (34.6%) and Internet gambling (26.9%) as the most important games, while most non-problematic gamblers pointed out the lotteries (62.3%) as the most important game. The prevalence of self-reported sleeping disorders, depression and other psychological impairments was significantly higher among problematic gamblers. Gambling problems affect people's lives in multiple ways. 相似文献
