BACKGROUND There is on going controversy on the effect of experimentally induced hypertension on nociception. The effect of salt-loading-induced hypertension on pain was studied in male rats. METHOD Twenty-four male Sprague-Dawley rats (160-280 g) were divided into two groups. Group A (n = 12) was treated with normal-feed diet (control), while group B (n = 12) was treated with 8% salt-loaded ...

Role of ethanolic extract of P. granatum seeds on central nervous system (CNS) in animal models of elevated plus maze test, barbiturate-induced sleeping time, tail suspension test, hot-plate and tail-flick test was studied. P. granatum (PG) extract was administered to young and aged mice at single doses of 100, 250 and 500 mg/kg, perorally while diazepam (1 mg/kg), morphine (5 mg/kg) and imipra...

Zingiber officinale Roscoe, commonly known as ginger, is a traditional herb used to treat various disorders. In this study, we evaluated potential pharmacological effects of ethanolic extracts of Z. Officinale with respect to central nervous system (CNS) activity in mice. Role of ethanolic extract of ginger on CNS activity in mice was studied using models of elevated plus maze test, barbiturate...

Hyperalgesia is one of the debilitating complications of diabetes. The thermal allodynia and hyperalgesia in diabetic mice may be due to the hyperactivity of C-fiber in the spinal cord. Transient receptor potential vanilloid type 1 (TRPV1) present in spinal cord and activation of C-fibre may involve in hyperalgesia in diabetic mice. Desipramine is one of the tricyclic antidepressants, effective...

In addition to its central actions, morphine has important peripheral effects. To examine peripheral analgesic mechanisms, we developed a topical opioid paradigm in which the tail was immersed in a dimethyl sulfoxide (DMSO) solution containing various drugs. Alone, DMSO was inactive in the tail-flick assay in mice. DMSO solutions containing morphine and peptides such as [D-Ala2,MePhe4, Gly(ol)5...

the selected parts of four medicinal plants, achillea millefolium, hibiscus rosasinensis, linum usitatissimum and pluchea lanceolata were extracted in absolute methanol to determine their analgesic activity. analgesic activity was assessed on intact mice by tail flick latency via the tail immersion method. the analgesic activities of these plant extracts were compared with acetylsalicylic acid ...

Objective- To evaluate antinociceptive efficacy of pre- versus post-incisional morphine, tramadol and meloxicam using tail-flick test in an incisional model of pain in rats. Design- Prospective, randomized experimental study. Animals- Eighty, adult, male Wistar rats weighing 250–300 g. Procedures- Animals were randomly divided into eight groups to receive pre- or post-incisional (tail skin i...
