Stress can be viewed as a cause of adverse circumstance that induces a wide range of biochemical and behavioral changes. Oxidative stress is a major contributor to the genesis of neurodegenerative and neuropsychiatric problems. In the present study, we investigated the protective effect of alprazolam in acute immobilization-induced various behavioral and biochemical alteration in mice. Mice wer...
in traditional medicine,some plants have been used as analysics.the aim of this investigation was to evaluate the analgesic effect of two plants,piper nigrum and Zingiber officinale that are used traditionally to relieve headache,rheumatic arthritis,and toothache.for this purpose the methanolic extract of zingiber and piper nigrum,in different doses,were injected intraperitonealy to mice and t...
Stress and chronic pain have been shown to prevent the development of tolerance to morphine analgesia, which appears to be related to neuroendocrine activity and alternation in neurochemicals. Also the involvement of nitric oxide (NO) has been implicated in tolerance to morphine analgesia. In our pervious study, we showed that co-administration of swim stress (ss) with chronic morphine, prevent...
One of the most ubiquitous examples of stress-induced analgesia that is easily observed is the pain reduction athletes experience during competition. There is anecdotal evidence for this phenomenon but there is an omission in the literature of conclusive systematic investigations of athletes' responses to noxious stimuli under competitive stress. The purpose of the present study was to examine ...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
