Hyperthermia was induced in mature rats by immersing them in 20 cm of 45 degrees C water for 4 min. Rats were made hyperthermic once every 4 days for six exposures. A significant number had at least one convulsion by the third exposure. During the seventh exposure, 2 weeks after the sixth exposure, twice as many rats experienced convulsions. Two weeks(More)
We previously demonstrated that behaviorally equivalent heat and cold stressors interacted with d-amphetamine (AMPH) treatment to produce different effects in rats responding for food on a fixed ratio 15 (FR15) schedule of reinforcement [25]. The present study was carried out to determine if these stressors differentially affect the disposition of AMPH to(More)
Electromagnetic field standards in the West are based on well-established acute biological effects that could be considered as signaling a potentially adverse health effect. The specific absorption rate, which is proportional to the tissue heating (thermal effects), represents the basic restriction of exposure to Radio-Frequency (RF) fields. On the other(More)
To ascertain whether behavioral effects of benzodiazepines are altered by exposure to microwave radiation, we compared the performance of male, Swiss CD1 mice in the staircase test 30 min after pretreatment with chlordiazepoxide (8, 16, and 32 mg/kg, IP) and immediately following a 5-min exposure to microwave radiation (4, 12, and 36 W/kg, continuous wave,(More)
Lessons learned from environmental and occupational hazard risk management practices over the past 30 years have led the Department of Defense to explore alternative risk management approaches. Policies for cleanup of environmentally hazardous waste sites are undergoing examination and are being reframed. A Demonstration Risk Communication Program is(More)
Radio frequency radiation exposure standards vary in origin, development process, legal status, and in the actual exposure limits. To identify the sources of differences in limits, we evaluated technical aspects of eight standards that included supporting information on the scientific data and rationale. Comparisons were made among the standards by(More)
Pigeons were injected intracerebrally with either puromycin (PM) or control saline solution following training for one 12-min session on a visual discrimination. Injections were made either immediately following training, 1 hr later or 24 hr later. Retention testing 3 days after training showed that PM produced marked amnesia in the first two groups, but(More)
