Perineural injection of clonidine at the site of nerve injury reduces hypersensitivity while simultaneously reducing leukocyte number and cytokine expression and hyperexcitability in sensory neurons. The activation of p38 mitogen-activated protein kinase in sensory neurons contributes to the development and...

This study examined the role of endocannabinoid signaling in stress-induced reinstatement of cocaine seeking and explored the interaction between noradrenergic and endocannabinergic systems in the process. A well-validated preclinical model for human relapse, the rodent conditioned place preference assay, was...

The inhibitory effect of clonidine (non-selective alpha2-adrenoceptor agonist) and oxymetazoline (alpha2A-adrenoceptor selective agonist) was compared on basal and stimulated gastric motor activity (gastric tone and contractions) using the balloon method in the rat. It was shown that oxymetazoline (0.2-1.7 micromol/kg...
