alpha 2-Agonist clonidine has been used for several years in the detoxification of opiate-addicts since it reduces withdrawal symptoms in man although craving for narcotic is not well suppressed. In the present work the potential "anticraving" properties of another alpha 2-agonist guanfacine were studied in rats trained to self-administer morphine. In the(More)
The enkephalin analogue peptide IKB-901 containing epsilon-ACA and cysteine with the modified S-end shows an analgetic activity in rats (1 micron, intrathecally and 5 mg/kg intravenously) and in cats (0.35 and 0.7 mg/kg intravenously). Naloxone (0.1 mg/kg) prevents the analgetic effect of peptide. The coadministration of the peptide and the enkephalinase(More)
It has been demonstrated in experiments on unrestrained and unanesthetized curarized cats that periaqueductal gray matter stimulation produce sympathetic-activating action, raise arterial pressure and heart rate, but at the same time is not effective enough to suppress the nociceptive shifts of haemodynamic reactions. Opioid mechanisms of spinal cord plays(More)
It has been demonstrated in experiments on nonanesthetized intact and spinalized cats that intrathecal morphine increased blood pressure and renal nerve sympathetic activity and enhanced the nociceptive reactions. It is suggested that morphine plays an essential role in the effect of propriospinal system on the generation of sympathetic spinal reflexes.
