Background. Ficus hispida is traditionally used in the ailment of pain, inflammation, and neurological disorders. The present study set out to evaluate the in vivo antinociceptive, anti-inflammatory, and sedative activity of the ethanol extract of Ficus hispida bark (EFHB). Methods. The antinociceptive activity of EFHB was evaluated by using acetic acid induced writhing, formalin, hot plate, an...

Prostatic acid phosphatase (PAP) is expressed in nociceptive neurons and functions as an ectonucleotidase. When injected intraspinally, the secretory isoforms of human and bovine PAP protein have potent and long-lasting antinociceptive effects that are dependent on A(1)-adenosine receptor (A(1)R) activation. In this study, we purified the secretory isoform of mouse (m)PAP using the baculovirus ...

OBJECTIVE The present study was undertaken to evaluate the antinociceptive effects of an ayurvedic polyherbal formulation in rats and mice employing the tail immersion test and acetic acid-induced writhing test, respectively. MATERIALS AND METHODS With the tail immersion method, rats received two different doses (270 and 405 mg/kg BW, p.o.) of a formulation, pethidine (5.4 mg/kg BW, p.o.) as ...

BACKGROUND Xanthosoma violaceum is commonly observed in fallow areas of Bangladesh but almost no scientific studies exist on this plant. Rural people consume the plant on a frequent basis. The objective of this study was to scientifically analyze the antinociceptive property of methanol extract of aerial parts of the plant along with antihyperglycemic activity. METHODS Antihyperglycemic activ...

BACKGROUND Artificial sweeteners are low-calorie substances used to sweeten a wide variety of foods. At present they are used increasingly not only by diabetics, but also by the general public as a mean of controlling the weight. This study was carried out to evaluate and compare antinociceptive activity of the artificial sweeteners, aspartame and sucrose and to study the mechanisms involved in...

Objective: The genus Marrubium is used for treatment of joint pain, gout, stomach-ache and colic in Iranian Traditional Medicine. Marrubium astracanicum Jacq. (M. astracanicum) is a native species in the flora of Iran. The aim of this study was to evaluate the antinociceptive properties of various extracts of aerial parts of M. astracanicum.Materials and Methods: Antinociceptive activities of t...

The antinociceptive effects produced by intraperitoneal administration of a novel synthetic chalcone, 3-(2,3-dimethoxyphenyl)-1-(5-methylfuran-2-yl)prop-2-en-1-one (DMFP), were investigated in several mouse models of induced nociception. The administration of DMFP (0.1, 0.5, 1.0 and 5.0 mg/kg) produced significant attenuation on the acetic acid-induced abdominal-writhing test. It also produced ...

Introduction: There is a major societal need for analgesics with less tolerance, dependence, and abuse liability. Preclinical rodent studies suggest that bifunctional ligands both mu (MOPr) delta (DOPr) opioid peptide receptor activity may produce analgesia reduced tolerance other side effects. This study explores the structure-activity relationships (SAR) of our previously reported MOPr/DOPr l...

The crude methanolic extract of the roots of Cerbera odollam Gaertn. was evaluated for its possible antinociceptive, antibacterial and diuretic activities in animal models. At the dose of 250 and 500 mg/kg body weight, the extract showed a significant antinociceptive effect in acetic acid induced writhing in mice comparable to that produced by aspirin, used as standard drug (P<0.001).The extrac...
