the development of combination therapy is a coherent approach in severe pain treatment. the present study investigated the antinociceptive effect of pregabalin alone and in combination with tramadol in acute pain modeling. therefore, three groups of male mice received either pregabalin (1 to 400 mg/kg), tramadol (10 to 80 mg/kg) or their combination intraperitoneally. then latency time, maximum...

calendula of.cinalis (asteraceae) is widely used in traditional medicine as an anti-in.ammatory agent and has also been reported to have anti-bacterial, anti-fungal and anti-viral activities.  sesquiterpene glycosides, saponins, triol, triterpenes and .avonoids are observed in its composition. the present study was designed to evaluate the antinociceptive effect of hydro-alcoholic extract of ca...

Recent neuroanatomical and behavioral evidence has indicated that vasopressin (VA) increases pain threshold. The dorsal raphe nucleus (DRN) is an important nucleus in pain modulation. Anatomical studies have shown that DRN receives vasopressinergic fibers originating in the hypothalamic paraventricular nucleus. The aim of the present study was to examine the effects of intra-DRN injection of de...

The latency of the heat-activated rat tail-flick (TF) reflex is dependent upon 4 variables, none of which has previously been determined: activation of cutaneous nociceptors (TN); afferent conduction to the dorsal horn (TA); conduction within the central nervous system (CNS) (central delay); and conduction from the ventral horn (VH) to, and activation of, tail muscles (TE). Using a CO2 infrared...

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...
