The antinociceptive activity of the methanolic extract of the leaves of Feronia limonia Linn. (Family Rutaceae) was investigated using acetic acid-induced writhing model and tail flick test in swiss albino mice. The extract produced about 26.01% ( p< 0.01), 39.88% ( p< 0.01) and 57.07% (p< 0.01) writhing inhibition at the dose of 100, 200 and 400 mg/kg of body weight respectively, which was comparable to the standard drug diclofenac sodium where the inhibition was about 63.58% (p< 0.01) at the dose of 25 mg/kg of body weight. All doses of extracts significantly (p<0.05) increased latency of flick tail in tail immersion method. The methanolic extract showed dose dependent antinociceptive activity in both type of test in swiss albino mice. Phytochemical investigations of the leaves extract indicate the presence of tannins, saponins, steroids, alkaloids and flavonoids. The preliminary study of the methanolic extract showed antinociceptive activity in both writhing and tail flick test in mice. http://dx.doi.org/10.3329/bjpp.v26i1-2.19962 Bangladesh J Physiol Pharmacol 2010; 26(1&2) : 21-24

Objective: Tectona grandis which is well known as teak possesses a wide range of applications in Indian and African folklore medicine. All the plant parts are having diverse bioactivities, especially the seeds, having hair growth-promoting activity, anti-inflammatory, and antimicrobial activity. Xanthones, proteins, amino acids, and fatty acids have been isolated from the oil and seeds of T. grandis. Methods: The present study was to explore the antinociceptive properties of methanolic seed extract of T. grandis. Dried seeds of the plant were defatted with non-polar solvents such as petroleum ether and extracted with methanol. Acetic acid-induced writhing test, tail flick test, and tail immersion test were employed for the extract using Swiss albino mice. Results: From the results, it is clear that the methanolic teak seed extract is safe at 1000 mg/kg and having a potent analgesic property (at a dose of 200–250 mg/kg body weight) by inhibiting pain response time. Conclusion: It can be concluded that the methanolic seed extract of T. grandis is analgesic in nature. It is considered as safe and the activity may be due to the presence of various bioactive chemicals such as flavonoids, xanthones, and glycosides.

Background: Pain is the most common reason for physician consultation in most countries. It is a major symptom in many medical conditions, and can interfere with a person's quality of life and general functioning. Acute pain is usually managed with medications such as analgesics and anesthetics. Cinnarizine is a piperazine derivative and Tramadol is an opioid analgesic. Cinnarizine is also a calcium channel blocker. So, in the present study an attempt has been made to access the antinociceptive activity of Cinnarizine alone & in combination with standard drug Tramadol with the hope of pharmacological synergism and better relief from pain. Material & Methods: 4 rats in 6 groups were weighed & colour coded. Basal reaction time to radiant heat was taken. Tail withdrawal time was recorded as the end point. Reaction time was taken at 0, 30 & 60 minutes on day 0, 7, 14, 21 & 28. Result: All observation were done by the ANOVA followed by post hoc Tukey’s. It is seen that Cinnarizine alone (in both doses) has antinociceptive activity but that is not statistically significant. But when it is given along with Tramadol it potentiates antinociceptive activity of Tramadol which is statistically significant. Conclusion: The result of this study conclude that Cinnarizine alone has antinociceptive activity in both doses (i.e 2.5mg/kg & 5mg/kg) but it is statistically not significant. Tramadol shows higher antinociception with Cinnarizine in dose of 5mg/kg than with 2.5mg/kg. Keywords: Antinociception, Cinnarizine, Tramadol, Tail flick test, Albino rats

Background: Serotonin and norepinephrine are important neurotransmitters involved in pain inhibition in descending pain inhibitory tracts. Venlafaxine being an antidepressant exerts its mechanism mainly by inhibiting reuptake of serotonin and norepinephrine like Tramadol. The objectives were to study the antinociceptive activity of Venlafaxine and its comparison with Pethidine.Methods: A total of 32 Swiss albino mice were divided into 4 groups with 8 animals in each group. Group 1 received normal saline as control in dose of 5ml/kg i.p, Group 2 received Pethidine as standard in dose of 30mg/kg s.c, Group 3 received Venlafaxine as in dose of 10mg/kg i.p and Group 4 received Venlafaxine in dose of 22.5mg/kg. Tail flick test and hot plate test were used for evaluating antinociceptive activity. All animals were subjected to the above mentioned tests before and 30 minutes after the administration of the drugs. Results were subjected to suitable statistical analysis.Results: The results from the above mentioned tests showed that Venlafaxine in dose of 10mg/kg showed significant antinociceptive activity as compared to normal saline (p <0.05) but was not comparable to Pethidine (p >0.05). Venlafaxine in dose of 22.5mg/kg showed significant antinociceptive activity as compared to normal saline (p <0.05) and activity was comparable to Pethidine.Conclusions: Venlafaxine in both the doses showed significant antinociceptive activity in acute models of pain in animals.

The study aims to evaluate analgesic and antipyretic activities of the methanol extract and its different fractions from root ofSchoenoplectus grossususing acetic acid induced writhing and radiant heat tail flick method of pain models in mice and yeast induced pyrexia in rats at the doses of 400 and 200 mg/kg. In acetic acid writhing test, the methanol extract, petroleum ether, and carbon tetrachloride fractions produced significant (P<0.001andP<0.05) inhibition of writhing responses in dose dependent manner. The methanol extract at 400 and 200 mg/kg being more protective with 54% and 45.45% of inhibition compared to diclofenac sodium of 56% followed by petroleum ether fractions of 49.69% and 39.39% at the same doses. The extracts did not produce any significant antinociceptive activity in tail flick test except standard morphine. When studied on yeast induced pyrexia, methanol and petroleum ether fractions significantly lowered the rectal temperature time dependently in a manner similar to standard drug paracetamol and distinctly more significant (P<0.001) after second hour. These findings suggest that the root extracts ofS. grossuspossess significant peripherally acting analgesic potential and antipyretic property. The phytochemical screening showed the presence of flavonoids, alkaloids, and tannins.
