Enhancement of pentazocine analgesia by clonidine.

abstract：:Since a number of patients with Parkinson's Disease (PD) complain of painful sensations, we studied whether the central processing of nociceptive inputs is abnormal in PD. To test this hypothesis, we recorded scalp CO(2) laser evoked potentials (LEPs) to hand skin stimulation in 18 pain-free PD patients with unilatera...
