We investigated the antinociceptive and anti-inflammatory activities of the crude ethanolic extract (CEE), its fractions, and the flavonoid isorhamnetin fromAspidosperma tomentosumusing models of nociception and inflammation in mice. In the writhing test, the CEE and its fractions (except for soluble phase, CHCl3100% and EtAcO 100%) at 100 mg/kg p.o. induced antinociceptive activity. Isorhamnetin (100 μmol/kg, p.o.) was also active. In the hot plate test, only the treatment with the fractions Hex : CHCl350%, CHCl3100%, and CHCl3 : MeOH 5% (100 mg/kg, p.o.) increased the latency time, reversed by the opioid antagonist naloxone. Fractions that were active in the hot plate test did not show catalepsy condition. It was observed that CEE, all fractions, and isorhamnetin reduced the formalin effects in the neurogenic phase. In the inflammatory phase, only CEE, isorhamnetin, and CHCl3100% and CHCl3 : MeOH 5% fractions were active. CEE and all fractions, except for CHCl3 : MeOH 10% fraction, isorhamnetin, and soluble fraction were able to produce an antioedematogenic activity in the ear capsaicin-induced edema test. In the thioglycolate-induced peritonitis, only EtAcO 100% fraction was not active. The results demonstrate thatA. tomentosumhas antinociceptive and anti-inflammatory activities in animal models.

Croton caudatus (Euphorbiaceae) is claimed to be useful in treatment of sprains, arthritis and liver disorders in traditional system of medicine. In the present investigation antinociceptive, anti-inflammatory and antipyretic effects of the 80% aqueous ethanolic extract from leaves of C. caudatus have been evaluated. The ethanolic extract reduced the nociception induced by acetic acid at dose of 100, 200 and 400 mg/kg significantly (P<0.001) and in dose dependent manner. In the hot plate test, the extract significantly increased the latency time of jump. The naloxone reversed the antinociception of the extract in hot plate test, indicating that C. caudatus ethanolic extract has morphinomimetic properties. The extract significantly decreased the rectal temperature in yeast-induced pyrexia in rats at highest tested dose.The ethanolic extract at a dose of 400 mg/kg produced 47% protection in carrageenan-induced edema. Steroids and/or triterpenoids, flavonoids and their glycosides are the major constituents of ethanolic extract of C. caudatus.

Abstract Background To investigate the antinociceptive and anti-inflammatory activities of aqueous extract of a blended mixture of dried leaves of Ocimum gratissimum and Psidium guajava, a traditional analgesic drug polyherbal (TADP) used as a remedy for pain-related conditions. Methods Antinociceptive activity of TADP (100, 200 and 400 mg/kg) was evaluated in the hot plate test and acetic acid-induced nociception in mice while the anti-inflammatory was evaluated in carrageenan-induced paw oedema in rats. Levels of nitrite, myeloperoxidase, glutathione and malondialdehyde were assayed in carrageenan-induced paw tissue. Results TADP (200 and 400 mg/kg) significantly prolong the latency time in the hot-plate test. TADP (100–400 mg/kg) produced a dose-dependent significant inhibition of the acetic-acid induced abdominal constriction. The antinociceptive activity of TADP in the presence of naloxone and atropine was not reversed whereas yohimbine and glibenclamide significantly reversed it. TADP (100, 200 and 400 mg/kg) significantly reduced the swelling in the carrageenan-induced oedema model and also produced a reduction in the nitrite and myeloperoxidase level. TADP (400 mg/kg) significantly reduced malondialdehyde concentration and increase glutathione level in the carrageenan-induced rat paw. TADP significantly decrease the number of cellular infiltrates in the histopathological assessment. Conclusion These results indicate that polyherbal product containing blended leaves of Ocimum gratissimum and Psidium guajava possess antinociceptive and anti-inflammatory properties, hence represents a promising alternative remedy in inflammation-induced pain.

Antinociceptive Effects

Infusions of roots of Siolmatra brasiliensis (Cogn.) Baill, (“taiuiá”, “cipó-tauá”) are used for toothache pain and ulcers. We aimed to study the antinociceptive effects and identify the possible mechanism of action of this plant and its isolated substances (cayaponoside A1, cayaponoside B4, cayaponoside D, and siolmatroside I). Hydroethanol extract (HE), ethyl acetate fraction (EtOAc), and isolated saponins were evaluated in chemical and thermal models of pain in mice. Animals were orally pretreated and evaluated in the capsaicin- or glutamate-induced licking and in the hot plate tests. The antinociceptive mechanism of action was evaluated using the hot plate test with the following pretreatments: Atropine (cholinergic antagonist), naloxone (opioid antagonist), or L-NAME (nitric oxide synthase inhibitor). All extracts and isolated saponins increased the area under the curve in the hot plate test. Tested substances induced a higher effect than the morphine-treated group. Our data suggest that stems of S. brasiliensis and their isolated substances present antinociceptive effects. Cholinergic and opioidergic pathways seem to be involved in their mechanism of action. Taken together our data corroborate the traditional use of the plant and expands the information regarding its use.

Borneol, a bicyclic monoterpene, has been evaluated for antinociceptive and anti-inflammatory activities. Antinociceptive and anti-inflammatory activities were studied by measuring nociception by acetic acid, formalin, hot plate, and grip strength tests, while inflammation was prompted by carrageenan-induced peritonitis. The rotarod test was used to evaluate motor coordination. Borneol produced a significant (P<0.01) reduction of the nociceptive behavior at the early and late phases of paw licking and reduced the writhing reflex in mice (formalin and writhing tests, resp.). When the hot plate test was conducted, borneol (in higher dose) produced an inhibition (P<0.05) of the nociceptive behavior. Such results were unlikely to be provoked by motor abnormality. Additionally, borneol-treated mice reduced the carrageenan-induced leukocytes migration to the peritoneal cavity. Together, our results suggest that borneol possess significant central and peripheral antinociceptive activity; it has also anti-inflammatory activity. In addition, borneol did not impair motor coordination.

Objective: The objective of the study was to evaluate the anti-inflammatory and antinociceptive effects of Artemisia afra.Methods: Animals were randomly divided into five groups of six animals each and administered with normal saline (2 ml/kg), indomethacin (10 mg/ kg), and A. afra at doses of 100, 200, and 400 mg/kg, respectively. For the anti-inflammatory activity, carrageenan-induced paw edema was used while the hot plate and acetic acid induced-writhing tests were used to assess the antinociceptive activity.Results: Pretreatment with A. afra at a dose of 100 mg/kg did not show any significant biological effects (p>0.05) for any of the three tests, when compared against saline-treated control group. At a dose of 200 mg/kg, A. afra demonstrated significant effects (p<0.01), during the 5th h reducing carrageenan-induced paw edema by 12%. The highest dose (400 mg/kg) of A. afra demonstrated more potent effects by decreasing the carrageenan-induced paw swelling (p<0.001–0.05) during the 3rd, 4th, and 5th h, by up to 38% when compared against saline-treated control group. Both the 200 and 400 mg/kg, A. afra doses achieved a significant increase (p<0.05) in reaction time in the hot plate test. In the acetic acid-induced writhing test, pretreatment with A. afra (400 mg/kg) significantly reduced pain by 39% (p<0.01) by comparison with the saline control.Conclusion: Experimental data demonstrated that aqueous extract of A. afra possesses anti-inflammatory and antinociceptive properties in experimental acute inflammation and pain. These findings support the usage of A. afra in managing inflammation and pain in traditional practice.

We attempted to identify the antinociceptive and anti-inflammatory actions of the monoterpene p-cymene. Firstly, behavioural screening was carried out to verify the influence of p-cymene [25, 50, and 100 mg/kg intraperitoneal (i.p.)] on the central nervous system (CNS) activity. The antinociceptive activity of p-cymene was evaluated by the acetic acidinduced writhing response, formalin, and hot-plate test, respectively. The leukocyte migration induced by injection of carrageenan was used to assess the anti-inflammatory activity. p-Cymene showed depressant activity on CNS after 4 h of treatment and also a possible action on the autonomous nervous system (ANS), mainly at the dose of 100 mg/kg (i.p.). It was found that p-cymene (50 and 100 mg/kg, i.p.) significantly (p < 0.05) reduced the writhing responses induced by acetic acid. p-Cymene also decreased the licking time in the first and second phase, respectively, of the formalin test. The results of the hot-plate test showed that all doses of p-cymene increased significantly the latency time of the response to the thermal stimulus in both licking and jumping parameters. In addition, there was a significantly (p < 0.05) decreased leukocyte migration at all doses of p-cymene. The experimental data demonstrate that p-cymene possesses antinociceptive and anti-inflammatory activities

Haloxylon Salicornicum

AbstractThe medicinal plant Haloxylon salicornicum is utilized for therapeutic purposes. We previously reported the antioxidant potential of hexane fraction and methanol extracts of the same species. However, since these solvents could be clinically toxic, the current findings investigated the pharmacological effects of the water fraction. The pain relieving, antioxidant, anti-inflammatory, and antipyretic potential of H. salicornicum water extract (HEW) were studied at two concentrations (250 and 500 mg/kg) in rodents. The carrageenan stimulated rat paw edema assay was exercised to assess anti inflammatory potential in rats; yeast-stimulated hyperthermia was utilized to test antipyretic activity in mice; analgesic properties were assessed based on acetic acid-induced writhing, tail flicking, and hot-plate test; and antioxidant potential was examined with the 2,2-diphenyl-1-picrylhydrazyl assay. We found that 500 mg/kg HEW inhibited edema by 44.03%. Yeast-induced hyperthermia in mice was reduced by 250 and 500 mg/kg HEW after 30, 60, and 120 min with significant level of (P < 0.001) compared to rectal temperature of yeast administered group. The high dose of HEW (500 mg/kg) improved the reaction time of mice in the hot-plate test from 6.66 ± 0.33 to 11.33 ± 0.49 s after 120 min. In the acetic acid-stimulated writhing test, 250 and 500 mg/kg HEW decreased writhing by 32.71% and 51.40%, respectively, after 20 min. HEW also showed antioxidant effects. These results demonstrate that HEW is bioactive and has therapeutic potential for treating a variety of ailments.
