Behavioural effects produced by intrathecal PWT2-[Dmt1]N/OFQ(1-13) in monkeys. A, percentage of maximum possible effect for antinociception measured by the warm water tail-withdrawal assay. B, scratching responses in a 15-min observation period after 3 nmol intrathecal of PWT2-[Dmt1]N/OFQ(1-13). Each data point represents the mean ± S.E.M. (n = 4). *P < 0.05, significantly different from vehicle from the first to the corresponding time point.
