The aqueous extracts of Acacia nilotica and Hibiscus sabdariffa were tested for anti-inflammatory, analgesic and antipyretic activities in animal models. Acacia nilotica extract had an inhibitory effect on carrageenan induced paw edema and yeast-induced pyrexia in rats. It also produced a significant increase in the hot plate reaction time in mice. Hibiscus sabdariffa extract had no effect on paw edema but had an inhibitory effect on yeast induced pyrexia and a significant effect on the hot plate reaction time. Among the phytoconstituents found in both plants, flavanoids, polysaccharides and organic acids may be mainly responsible for their pharmacological activities.

Background: A major goal of pain management is to provide pain relief that is clinically meaningful, sustained, and associated with minimum and reversible adverse effects. Since single analgesic drug is not effective in all patients, there is a need either to develop new and more effective drugs or to identify favourable combinations of drugs that are already available. The aim of the present was to evaluate the analgesic and anti-inflammatory activity of tramadol and pregabalin when used alone or in combination in animal models of pain and inflammation.Methods: The animals (rats and mice) were divided into eight groups with six animals in each group. Analgesia was assessed by acetic acid induced writhing and tail flick methods in mice and hot plate method in rats. Paw oedema model in rats after induction with 0.1 ml of 1% carrageenan was used to assess the anti‑inflammatory activity. The percentage inhibition of writhes and prolongation of reaction time were used for assessing analgesic activity and reduction in paw volume was used for assessing anti-inflammatory activity. The results obtained were analysed by ANOVA and Tukey HSD Post-hoc Test.Results: Treatment with tramadol pregabalin alone or in combination reduced writhing episodes significantly in acetic acid induced writhing in mice as compared to control indicating its analgesic effect and the highest percentage inhibition of pain was seen with high dose tramadol plus pregabalin. Treatment in Hot plate and Tail flick methods significantly prolonged the reaction time at all time points.Conclusions: Tramadol when combined with pregabalin may enhance its anti-nociceptive effects. If confirmed in additional models of acute and/or chronic pain this combination might be useful in the clinical management of pain not associated with inflammation.

Background: Pain and inflammation are disabling accompaniments of many medical conditions. So, controlling both pain and inflammation assumes the top priority for the physician. Inflammation is a part of a complex biological response of vascular tissues to harmful stimuli such as pathogens, chemicals or irritants. Therapy of pain and inflammation has always been debatable.Methods: Rats were divided into 8 groups of 6 animals of each. The anti-inflammatory activity was studied with carrageenan induced rat paw edema and cotton pellet induced granuloma models. The analgesic activity was evaluated using Eddy’s hot plate model. The aqueous extract of Rubia cardifolia root and Cassia fistula leaf preparations were compared with Diclofenac in both acute and sub acute inflammatory models and also in pain model.Results: Various test result parameters were statistically analysed at P value <0.5. In Eddy's hot plate model both RC and CF preparations prolonged the response reaction time, while CF preparation showed longer reaction time than that of RC preparation. In carrageenan induced paw edema and cotton pellet induced granuloma models, both RC and CF preparations showed significant decrease in paw edema volume and granuloma dry weight respectively, but less than that of Diclofenac. RC preparation found to have dose dependant in inflammatory models.Conclusions: RC root and CF leaf preparations were compared head to head and they have been found to have significant dose dependant analgesic activity and dose independent acute and sub acute anti inflammatory activities. Though CF leaf preparation appeared to be a good analgesic than RF root preparation, but failed to do so as an anti inflammatory agent in both inflammatory models. But both test preparations were not equivalent to Diclofenac in all three models.

Background: The onion plant (Allium cepa) is the most widely cultivated species of the genus Allium. It has antibiotic, antidiabetic, antihypercholesterolemic, antioxidant, hemostatic, antimutagenic effects. The current study is aimed to evaluate analgesic and anti-inflammatory properties of Allium cepa extracts in rat models.Methods: In this study analgesic activity in rats is tested by Eddy’s hot plate method, tail flick method. In Eddy’s hot plate method rats are individually placed on the heated plate of the analgesic meter maintained at 550C and mean reaction time was calculated at regular time intervals. In tail flick method the tail withdrawal from the heat (flicking response) is taken as the end point. Anti-inflammatory property is studied by carrageenan induced paw edema model, in which the paw volume is measured with a plethysmograph.Results: In Eddy’s hot plate method the mean reaction time increased significantly (p<0.05) with high dose of Allium cepa at 1 hour and 2 hours when compared to control. In tail flick method the mean reaction time is increased significantly (p<0.05) with high dose of Allium cepa at 1 hour and 1.5 hour when compared to control. In carrageenan induced paw edema method Allium cepa exhibited anti-inflammatory activity by significant (p<0.05) suppression of paw edema when compare to control at 1 hour after carrageenan injection to rat paw.Conclusions: Allium cepa has significant analgesic and anti-inflammatory activity in hot plate, tail flick and carrageenan induced paw edema model.

Background: Woodfordia fructicosa is used traditionally for the treatment of inflammation associated with arthritis. Methods: In the present study, the anti-inflammatory activity of W. fructicosa (WFE) leaves ethanolic extract was assessed in Sprague Dawley rats by giving 200 mg/kg dose orally. Inflammation was studied by using carrageenan induced paw edema, Freund’s adjuvant (FA) and monosodium iodo acetate (MIA) induced arthritis as animal models. Serum tumor necrosis factor-alpha (TNF-α) was estimated in blood sample of animals treated with FA. The one way ANOVA followed by Bonferroni’s test was used for statistical analysis. Results: WFE significantly decreased (P<0.05, P<0.001) paw thickness in carrageenan induced paw edema and FA induced arthritis. The significant decrease in knee diameter (P<0.001) in MIA induced arthritis as well as inhibitory effect (P<0.001) on elevated TNF- α was observed. Conclusion: These results showed that the WFEexerted an inhibitory effect on TNF-α and carrageenan paw edema which may justify its traditional use in inflammatory conditions. Thus, the study shows that leaves of W. fruticose afford anti-inflammatory activity by preventing the inflammation in different animal models.

ABSTRACT The present study was designed to investigate the antioxidant, antinociceptive and anti-inflammatory activities of the ethanol extract from Ageratum fastigiatum branches. Phytochemical screening and total phenol and flavonoid contents were determined. The antioxidant activity was assessed by 2,2-diphenyl-1-pycrilhydrazin (DPPH) and iron reducing power methods. The antinociceptive effect was evaluated using the acetic acid-induced writhing, formalin, hot plate and tail immersion assays; while the carrageenan-induced paw edema and pleurisy tests were performed to examine the anti-inflammatory activity against acute inflammation. The extract revealed the presence of flavonoids, tannins, coumarins, terpenes, sterols and saponins. Expressive levels of total phenols and flavonoids and a promising antioxidant effect were quantified. At the doses of 50, 100 and 200 mg/kg, the extract inhibited the writhing, reduced both phases of paw licking time and increased the reaction time on the hot plate. In the tail immersion test, the extract (50, 100 and 200 mg/kg) caused a significant inhibition of pain. In these doses, the paw edema, exudate volume and leucocyte mobilization were significantly reduced. These results suggest that A. fastigiatum can be an active source of substances with antioxidant, antinociceptive and anti-inflammatory activities, adding scientific support to the appropriate use in the Brazilian folk medicine.

We have developed a series of aminoacetylenic isoindoline-1,3-dione compounds and showed their anti-inflammatory activities by reducing carrageenan-induced rat paw edema and modulating proinflammatory and anti-inflammatory cytokines. In the present study and due to efficacy reasons, we are exploring only two of these compounds, namely, ZM4 and ZM5, to reveal their analgesic activity and toxicity. Following oral administration, both compounds were effective in reducing significantly (P<0.05–0.001) acetic acid-induced writhing behavior, hot plate latency test, and formalin-induced paw licking time as antinociceptive indicators in mice and rats, respectively. Regarding the toxicity, the acute (20, 50, and 150 mg/kg) and repeated oral administration (10, 20, and 50 mg/kg) of these compounds for ten days did not produce any mortality and the compounds were considered well tolerated. However, repeated oral administration of 50 mg/kg of both compounds induced erythropoiesis by means of increasing significantly red blood cells, hemoglobin, and packed cell volume. Moreover, these compounds did not induce gastric lesions in the stomach of experimental animals at the doses that exhibited analgesic and anti-inflammatory activity compared to indomethacin as a positive control. The results indicate that ZM4 and ZM5 possess potential analgesic activity while being preliminarily safe and have minimal ulcerogenic activity.

"Ham-Hong-Chho" is a folk medicine in Taiwan, derived from the entire plants of Bidens pilosa L. var. minor (Blume) Sherff (Compositae), B. pilosa L. and B. chilensis DC. The anti-inflammatory effect of aqueous extracts of the three plants against paw edema induced by carrageenan and chronic arthritis induced by complete Freund's adjuvant were determined in rats. The results indicated that paw edema induced by carrageenan was significantly decreased by treatment with aqueous extracts (150 or 300 mg/kg) of all three plants ( p < 0.05) and that the effect of Bidens pilosa var. minor was the most potent. However, only extracts (500 mg/kg) of B. pilosa L. var. minor and B.pilosa L. significantly decreased the paw edema induced by complete Freund's adjuvant ( p < 0.05).

The current study was performed to evaluate the antinociceptive and antiedematogenic properties of andrographolide isolated from the leaves of Andrographis paniculata using two animal models. Antinociceptive activity was evaluated using the acetic acid— induced writhing and the hot-plate tests, while antiedematogenic activity was measured using the carrageenan-induced paw edema test. Subcutaneous (s.c.) administration of andrographolide (10, 25, and 50 mg/kg) did not affect the motor coordination of the experimental animals but produced significant (p < .05) antinociceptive activity when assessed using both tests. However, 2 mg/kg naloxone failed to affect the 25 mg/kg andrographolide activity in both tests, indicating that the activity was modulated via nonopioid mechanisms. Furthermore, andrographolide showed significant (p < .05) antiedematogenic activity. In conclusion, the results obtained suggest that andrographolide has antinociceptive and antiedematogenic activities; it may be useful for treating pain and inflammation once human studies are conducted.
