bulbospinal noradrenergic pathways are shown to have an important role in descending inhibition of pain sensation. locus ceruleus (lc), as a rich noradrenergic nucleus in the brain stem which has projections into the dorsal horn of the spinal cord, was evaluated for antinociceptive activity by using tonic and phasic pain models in the rat. lc-lesioned rats demonstrated moderate increase in both...
The locus ceruleus is among the earliest affected brain regions in Parkinson’s disease (PD) showing Lewy body pathology and neuronal loss. To improve our understanding of the pathogenesis of PD, we performed the first proteomic analysis ever of post-mortem locus ceruleus tissue of six pathologically confirmed PD patients, and six ageand gendermatched non-neurological controls. In total 2495 pro...

In this study, the effect of reversible inactivation of locus ceruleus (LC) on naloxone- induced withdrawal syndrome in paragigantocellular (PGi) neurons in morphine- dependent rats was investigated. For inactivation of LC, 1 µl of lidocaine (2%) was used and for induction of withdrawal syndrome, naloxone hydrochloride (2 mg/kg) was injected systemically. The results showed that in dependent gr...
We studied the actions of vasopressin administered microiontophoretically onto neurons of the locus ceruleus in rats with deoxycorticosterone-acetate (DOCA)-salt hypertension and in control (normotensive) rats. Rats were studied at 3 days (prehypertensive stage) and 4 to 6 weeks after DOCA-salt treatment (chronic hypertensive stage). Experiments were performed in anesthetized rats using convent...
