Previous studies have indicated that stressful footshock can induce both opioid, naloxone-sensitive, and non-opioid, naloxone-insensitive forms of analgesia, depending on stimulation parameters used with 30 min of intermittent footshock (3 mA, 1 s on, 5 s off) producing opioid analgesia and 3 min of continuous shock (3 mA) producing non-opioid analgesia.(More)
Reports by several investigators have shown that both opioid and non-opioid analgesia can be induced by non-pharmacological manipulations such as the administration of electric shock, and that such analgesia depends on shock parameters, the affective state of the animal and the region of the body shocked. We tested several manipulations which have been(More)
OBJECTIVE Growth retardation is an established complication of anorexia nervosa (AN). However, findings concerning final height of AN patients are inconsistent. The aim of this study was to assess these phenomena in female adolescent inpatients with AN. METHODS We retrospectively studied all 211 female adolescent AN patients hospitalized in an inpatient(More)
The administration of electric shock to the feet of rats can produce either opioid, naloxone-sensitive analgesia or non-opioid, naloxone-insensitive analgesia. In our hands opioid analgesia could be elicited in young Sabra rats (75 days of age) by all analgesia induction methods while older rats of the same strain and rats of the Charles River-derived(More)
