Hypothalamic corticotropin releasing factor-like immunoreactivity (CRF-LI), plasma ACTH and corticosterone levels were measured by radioimmunoassay over a two hour period of restraint stress. The results of this study demonstrate a significant decrease in hypothalamic CRF-LI levels 15 and 30 minutes after the start of restraint stress which is followed by a(More)
The operative management of open fractures of the lower limb requires a consistent treatment to avoid soft tissue complications. Acute angular shortening of the fracture enabling primary soft tissue closure is still an uncommon operative technique because of difficulties in correcting the secondary deformity. The case of a pediatric open fracture of the(More)
We analyzed the adequacy of pain control for 17 trauma patients during the initial part of their stay in the intensive care unit, and assessed reasons for inadequate analgesia, if it occurred. Patients, and physicians, and nurses were interviewed. A verbal pain intensity scale was used to determine whether patients received adequate analgesia. Patients were(More)
The effect of constant light and constant dark on the circadian rhythm of the concentrations of hypothalamic corticotropin-releasing-factor-like immunoreactivity (CRF-LI), plasma ACTH, and corticosterone was investigated. Groups of rats were maintained under normal light-dark, constant light, or constant dark conditions for 10 days. Rats were then killed(More)
PURPOSE Distal radius and forearm fractures are injuries that are frequently seen in trauma surgery outpatient clinics. Usually, the wrist is X-rayed in 2 planes as standard diagnostic procedure. In contrast, we evaluate in our study the accuracy of ultrasonography (US) in diagnosing these fractures. METHODS This prospective study includes the patients(More)
Daily intravenous evening injections of 30 nmol/kg DSIP (Delta Sleep-Inducing Peptide) in rats adapted to a constant 24 hr light:dark cycle produced changes in the circadian locomotor behavior. After 3 days the normally high locomotor activity during the dark phase was reduced while during the light (sleeping) phase the animals became relatively more(More)
Peptide research, like all of science, requires a careful balance between building upon previously accumulated knowledge and exploring perspectives that are in conflict with prevailing views. Many of the concepts discussed here originally stimulated certain lines of research. The downfall of most of these concepts, and thus their misleading nature, lies in(More)
Since the turn of the century, it has been postulated that humoral factors induce sleep. Many compounds were proposed as sleep-factors, but only two of the sleep-peptides have been purified to homogeneity and characterized, so far. One of them, DSIP, was shown to be a nonapeptide of MW 849 and to induce mainly delta-sleep in rabbits, rats, mice, and humans,(More)
The delta sleep-inducing peptide (DSIP) has been shown to induce effects other than only delta sleep. One of these effects was the paradoxical thermoregulatory and locomotor response of rats to amphetamine after DSIP administration. In the present investigation we found similar effects of DSIP on the locomotor activity in mice. However, two different doses(More)
