The aims of this study were to evaluate the anti-inflammatory and analgesic effects of bufalin, a major component of "Chan-su." We used a carrageenan-induced paw edema model to assess the anti-inflammatory activity of this compound, and Western blot analysis detected NF- κ B signaling during this effect. The antinociceptive activities were evaluated by acetic acid-induced writhing, formalin, an...

The present study was designed to investigate the role of strychnine-sensitive glycine receptors in hypnosis and analgesia induced by emulsified volatile anesthetics. After having established the mice model of hypnosis and analgesia by intraperitoneally injecting (i.p.) appropriate doses of ether, enflurane, isoflurane or sevoflurane, we intracerebroventricularly (i.c.v.) or intrathecally (i.t....

Our previously conducted pharmacological investigations led us to discovery of the strong local anesthetic activity of the compound KP-23RS. The following studies revealed that its Rand S-diasteroisomers had different activity in the local anesthetic, anti-aggregating, anti-arrhythmic and spasmolytic tests. Also the influence of KP-23RS and its diastereoisomers on the cyclic adenosine monophosp...

In this study, the response of female rats in different phases of the estrus cycle to nociceptive stimulation was evaluated using thermal (hot plate and tail immersion) and chemical (formalin) tests. In the hot plate test, the paw licking latency fell significantly (p < 0.05) in the metestrus and diestrus phases compared with the proestrus and estrus phases. The observations in the tail immersi...

The present study is a designed protocol for investigation of the analgesic effect of oral and intraperitoneal (i.p.) administration of alcoholic Datura stramonium (DS) seed extract as a rich source of alkaloid substances. Male NMRI rats were divided into control and treatment groups. The treatment rats received different doses of the DS seed extract, which was prepared from alcoholic smashed s...

The antinociceptive activity of mycelial extract from fermented mushroom of Ganoderma lucidum Coprinus comatus and Grifola frondosa were studied in this paper. The writhing test, formalin test and hot-plate test were used to evaluate the antinociceptive activity of the acetone extracts of the three Species of Fungi of Basidiomycetes in the study respectively. The extract of Ganoderma lucidum in...

objectives this study was designed to evaluate the antinociceptive activity of methanol extract of n. depauperata in male mice. materials and methods the anti-nociceptive activities of the extract were investigated by the formalin test and hot plate test respectively. comparisons between the groups were carried out using one-way analysis of variance (anova), and post hoc tukey test. results n. ...

AIM To investigate the involvement of L-type Ca(2+) channels in antinociceptive action induced by the 5-HT precursor, 5-hydroxytryptophan (5-HTP). METHODS Female Kunming mice were treated with either 5-HTP (20-80 mg/kg, ip) alone, or the combination of 5-HTP and fluoxetine (2-8 mg/kg, ip), pargyline (15-60 mg/kg, ip), nimodipine (2.5-10 mg/kg, ip), nifedipine (2.5-10 mg/kg, ip), verapamil (2....

Isodon rugosus Wall. ex Benth. is extensively used as traditional medicine for the management of various types of pain including tooth ache, gastric pain, abdominal pain, ear ache, and generalized body pain. The current study is designed to scientifically verify the purported uses of I. rugosus as analgesic agent and to figure out its possible mechanism of action. Bioactive compounds responsibl...
