The study investigated the anti-nociceptive and anti-inflammatory properties of a Nigerian Polyherbal Health Tonic tea aqueous extract (PHT) in rodents of both sexes. 100-500 mg kg(-1) of the aqueous extract was administered via the intra-peritoneal (i.p.) and oral (p.o.) routes to 5 groups of mice using tail immersion, tail clip, formalin and acetic acid-induced writhing tests of experimental ...

Traditionally aerial parts of Barleria prionitis Linn. has been used in the inflammation, fever & toothache. The present study was undertaken to evaluate the anti-inflammatory and anti-nociceptive activity of 50% ethanolic extract of the flower of B. prionitis (BPF) in experimental animals. The BPF in doses of 50, 100 and 200 mg/kg caused a dose-dependent inhibition of swelling caused by carrag...

The present study investigated the role of calcitonin gene-related peptide (CGRP) in the modulation of nociception in periaqueductal grey (PAG) of rats. Hindpaw withdrawal latencies (HWLs) were tested by hot-plate and Randall Selitto tests. The HWLs to thermal and mechanical stimulation increased significantly after intra-PAG administration of 0.26 or 0.13 nmol of CGRP, but not 0.026 nmol of CG...

Considering the importance of a deeper understanding of the effect throughout life of opioid analgesia at birth, our objective was to determine whether morphine administration in early life, once a day for 7 days in 8-day-old rats, alters the nociceptive response over the short (P16), medium (P30), and long term (P60) and to evaluate which system is involved in the altered nociceptive response....

  In this study interaction of three types of calcium channel blockers nifedipine, diltiazem and verapamil on the effects of lead acetate on two types of pain (nociception and inflammation) induced by formalin in mice were examined. In order to study nociception, formalin test was selected because of greater resemblance to clinical pain. Lead acetate (50, 75, l00, 125 and 150 mg/kg) administere...
