It has been suggested that exposure to the elevated plus-maze (EPM) apparatus induces antinociceptive effects in mice as measured by the tail-flick assay, which are not blocked by the opiate antagonist naltrexone. The present study performed on 3-month old male EPM-M1 albino mice (12-14 animals per group) was designed to assess a) if exposure limited to the(More)
The effects of single (2.5 and 5.0 mg/kg) and long-term (2.5 mg/kg, twice daily, for 30 days) ip administration of nifedipine on open-field and apomorphine-induced stereotyped behavior were evaluated in young male Wistar rats (12-16 animals per group for the open-field studies and 7 animals per group for the stereotypy experiments). Administration of a(More)
In the present investigation, nociception and stereotyped behavior were evaluated in 3-month old male Wistar rats after a single nifedipine dose (2.5 and 5.0 mg/kg, ip, 1 h before testing, 6-7 rats per group for stereotypy studies and 15 animals per group for nociception experiments) or after long-term nifedipine treatment (2.5 mg/kg, ip, twice daily for 30(More)
