value to the physician and non-clinician who are concerned with the history, etiology, prevention, safety, and/or medical management of head injury. The book is well referenced to include the major contributions from the literature for prevention and management of head trauma both present and from antiquity. The intent of this book, if one were to judge(More)
Rats were given passive avoidance training within a distinctive environment followed by subseizure level stimulation of the hippocampus or amygdala. The animals were then tested for retention of the aversive experience using a partial cue (subset of the original training environment) and a complete cue (the original training environment). Post-trial(More)
Rats with injections of 4 or 8 mg/kg of phencyclidine (PCP) are impaired in the acquisition of active avoidance learning and radial arm maze performance. This impairment was not due to a change in detectability of aversive stimuli or the inability to perform the correct response. The primary deficit appears to be the inability of PCP injected animals to(More)
In 10 out of 11 patients with colorectal cancer radiolabelled antitumour monoclonal antibody (791T/36) was localised to the tumour. The mean tumour to non-tumour uptake ratio of antibody demonstrated by imaging with a gamma camera was 4.4/1 after subtraction of background radioactivity. The antibody did not localise in one patient who had received(More)
Four volunteers judged eight levels of thermal stimuli induced by a Hardy dolorimeter, varying in intensity from extremely painful to a low level seldom even perceived. Half of the 406 stimuli were applied during acupuncture and half either before insertion or after removal of the needles. The experimental design minimized or eliminated factors other than(More)
Previous research has indicated that high scores on the Cook and Medley Hostility (Ho) scale are associated with increased risk of coronary heart disease and other illness. Our study attempts to clarify this relationship by providing additional evidence concerning the construct assessed by the Ho scale, examining the level of physiological reactivity during(More)
Phencyclidine (PCP) injections in rats at doses of 4 mg/kh increased activity level, which might have been a function of impaired habituation. At doses of 8 mg/kg PCP produced a marked reduction in activity level. At doses of 12 mg/kg and above there were profound disruptive effects in detection of odors, visual square and touch measures, and performance of(More)
