Brenania brieyi (Rubiaceae) is widely used in traditional Congolese medicine in the treatment of many pathologies that are manifested by inflammation, pain and fever. The objective of this study was to study the acute toxicity as well as to evaluate the antipyretic, analgesic and anti-inflammatory effects of the aqueous and hydro-ethanolic extracts of Brenania brieyibark on models of pyrexia, algesia and inflammation induced in rodents. The aqueous extract of Brenania brieyidoes not cause any mortality up to the dose of 4000 mg/kg, but promotes a slight increase in body weight. From 2000 mg/kg, the signs of toxicity observed were the significant decrease in mobility as well as the loss of alertness. At doses of 100 and 200 mg/kg, aqueous and hydro-ethanolic Brenania brieyiextracts showed a very significant anti-inflammatory effect (***p< 0.001) on edemas induced by carrageenin (1%), formaldehyde (2.5%) and histamine (1 mg/mL), greater than that of diclofenac at 10 mg/kg. At 200 mg/kg, both extracts showed a very significant analgesic effect (***p< 0.001), greater than that of paracetamol 100 mg/kg against pain induced by acetic acid 0.6% and formaldehyde 2.5%. Brenania brieyiwas slightly effective in the tail flick test. Brewer's yeast-induced hyperthermia was reduced by both extracts. However, the hydro-ethanolic extract proves to be more effective than the aqueous extract in all the tests carried out. These pharmacological effects would be related to the presence of alkaloids, tannins, flavonoids, anthraquinones, oses and saponosides.

Synadenium umbellatumPax., popularly known in Brazil as “cola-nota,” “avelós,” “cancerola,” and “milagrosa”, is a plant species used in folk medicine for the treatment of inflammation, pain, and several diseases. This study aimed to investigate the antinociceptive and anti-inflammatory activities of the ethanolic extract fromSynadenium umbellatumPax. leaves (EES) and its hexane (HF), chloroform (CF), and methanol/water (MF) fractions using the acetic acid-induced abdominal writhing test, formalin-induced paw licking test, tail flick test, croton oil-induced ear edema test, and carrageenan-induced peritonitis test. EES and MF reduced the number of acetic acid-induced abdominal writhes, while CF and HF did not. EES effect on acetic acid-induced abdominal writhing was reversed with a pretreatment with naloxone. EES reduced licking time in both phases of the formalin-induced paw licking test, but did not prolong the latency in the tail flick test. These results show that EES presented antinociceptive activity, probably involving the opioid system, anti-inflammatory activity in the croton oil-induced ear edema test, and leukocyte migration into the intraperitoneal cavity. MF also presented anti-inflammatory activity in the croton oil-induced ear edema test. In conclusion, EES and MF have antinociceptive activity involving the opioid system and anti-inflammatory activity.

Background: The use of natural compounds in relieving pain has been commonplace since ancient times and their use is currently increasing. Objectives: Given that analgesic and anti-inflammatory effects of Kombucha have not been studied, this study was designed to examine these effects in vitro. Methods: In this experimental study, rats were divided into four groups. The control group received normal saline i.p in the same amount of the drug. The other groups received Kombucha tea i.p at 250, 500, and 1000 mg/kg. Tail-flick and acetic acid tests were used to evaluate the analgesic effects of Kombucha tea and the xylene-induced ear inflammation test to evaluate the anti-inflammatory effects of Kombucha tea. Results: Kombucha tea at three doses 250, 500, and 1000 mg/kg significantly reduced the number of writhings in the acetic acid test. Kombucha tea at 1000 mg/kg significantly increased pain tolerance in the tail-flick test. Kombucha tea at 250 and 500 mg/kg could significantly reduce inflammation in the rat’s ear. Conclusions: The results of this study indicate that Kombucha has analgesic effects in rats and can be considered in future treatments.

Ziziphus mistol Griseb. (Rhamnaceae), popularly known as “mistol,” is widely distributed throughout Perú, Bolivia, Paraguay and Argentina. Its fruit is consumed in different forms in several argentinean communities and used against biliary colic, dysentery, cold stomach and diseases of the respiratory system characterized by pain and inflammation. The present study was carried out to investigate the medicinal properties and safety of Ziziphus mistol (mistol) fruits ethanol and aqueous extracts and arrope. Antinociceptive activity was assessed using the formalin, acetic acid-induced writhing and tail-flick tests in rats. Anti-inflammatory effects were determined through carrageenan induced edema test and cotton pellet-induced granuloma formation, in rats. The safety was evaluated with test of acute toxicity (48 hours) and sub-chronic toxicity (91 days). All extracts (1,000 mg/kg b.w.) showed significant inhibition (P less than 0.05) in the three model of pain experimentally induced in comparison to control. In a combination test using naloxone, diminished analgesic activity of aqueous extract and arrope were observed, indicating that their antinociceptive activity is connected with the opioid receptors. At dose 1000 mg/kg bw, the aqueous extract and arrope showed higher anti-inflammatory activity than the ethanol extract, in carrageenan and cotton pellet granuloma model used. In the acute toxicity study, a single dose of 4000 and 8000 mg/kg b.w., produced no mortality and no clinical signs of disease were observed after 48 hours. In the sub-chronic toxicity study the extracts no caused significant visible signs of toxicity, nor mortality for 91 consecutive days of treatment. Extracts and arrope of Z. mistol fruits could be good source of antinociceptive and anti-inflammatory agents because of its good activity and safety.

AbstractThe objective of this study was to investigate the antinociceptive, anti-inflammatory, thrombolytic and hepatoprotective activities of root extracts ofThe analgesic activity was evaluated using the acetic-acid-induced writhing test in mice and radiant heat tail-flick method in rats. The anti-inflammatory activity was investigated by carrageenan-induced rat’s paw edema, while the thrombolytic activity was evaluated by in vitro clot lysis model. The hepatoprotective activity was investigated against carbon-tetrachloride-induced liver damage in rats.In acetic-acid-induced writhing test, chloroform and ethyl acetate fraction of ethanolic extract at a dose of 200 mg/kg showed a significant (p<0.001) reduction in the number of writhes with 85.96% and 61.98% of inhibition, respectively. In radiant heat tail-flick method, the ethanolic extract produced 88.49% (p<0.001) elongation of tail-flicking time at 90 min after oral administration at same dose level. In the carrageenan-induced edema test, the ethanolic extract at a dose of 200 mg/kg showed a significant inhibition of paw edema with 22.68% and 17.24% inhibition after the first and third hours of the study period, respectively. In clot lysis model, the ethanolic extract at 5 mg/mL induced a significant clot lysis activity (37.69%, p<0.001). Oral administration of ethanolic extract at the dose of 400 mg/kg/day for 7 days significantly (p<0.001) reduced the elevated levels of serum glutamic pyruvic transaminase, serum glutamyl oxaloacetate transaminase and alkaline phosphatase compared to the CClThe results of the study demonstrated the antinociceptive, anti-inflammatory, thrombolytic and hepatoprotective activities of roots of

The Streptoverticillium sp. Z1 is an actinomycete isolated from the soil under Cerrado vegetation, the extract of this strain was investigated in nociceptive and inflammatory models. The Streptoverticillium extract (ExS) 50 and 100 mg/kg (s.c.) produced a significant inhibition of acetic acid-induced abdominal writhings thereby demonstrating an anti-nociceptive effect. In the tail flick test the ExS (s.c.) was inactive. This result implited that ExS does not contain opioid-like compounds with central analgesic properties. In the inflammatory models, ExS 100 and 200 mg/kg (s.c.) were able to inhibit the croton oil-induced ear edema and, ExS 200 and 500 mg/kg (s.c.) inhibited the leukocyte migration on the carrageenan-induced peritonitis. The phospholipase A2 enzymatic assay showed that the anti-inflammatory activity of ExS was not due to direct effect on phospholipase A2 activity. These data suggest that Streptoverticillium sp. produces metabolites with anti-inflammatory effect and that these metabolites are unable to directly inhibit phospholipase A2 enzyme.

AbstractBackground and objectivesAloperine (ALO) is an alkaloid compound and presents in several medicinal plants. This study was undertaken to investigate the anti-nociceptive and anti-inflammatory activities of ALO on various chemical- and thermal-induced hypersensitivity models in mice.MethodsThe anti-nociceptive effect of ALO was evaluated using acetic acid-induced writhing test, hot plate test, tail flick test, formalin test, ear swelling test, locomotor activity test, rota-rod test and carrageenan-induced paw edema test in mice. Inflammatory cytokines including interleukin-10 (IL-10), tumor necrosis factor α (TNF-α), interleukin-1 beta (IL-1β) and prostaglandin E2 (PGE2) expression were examined in ALO- and vehicle-treated mice.ResultsThe results showed that ALO significantly attenuated acetic acid-induced writhing numbers in mice in a dose-dependent manner. ALO showed no effect on prolonging latency in the hot plate test and the tail-flick test. ALO showed analgesic activity in the inflammatory phase of formalin-induced pain. Its anti-inflammatory effect was also confirmed in the ear-swelling test. In the carrageenan-induced paw edema model, ALO significantly and dose-dependently reduced the carrageenan-induced paw edema, decreased the contents of TNF-α IL-1β and PGE2, but increased the IL-10 production. On the other hand, ALO showed no influence on the rota-rod performance time or on spontaneous locomotor activity.ConclusionIt is concluded that ALO has both anti-inflammatory and analgesic effects, especially in the field of inflammation pain.ImplicationsOur findings support the hypothesis that ALO ameliorates inflammatory pain induced by chemical and thermal stimuli and provides a scientific basis for the resource development and clinical use of aloperine.

The paper presents the synthesis of a new complex combination of a Bis-Schiff base with Mn(II) ions with great potential for antimicrobial and anti-inflammatory activity. A new complex of the Salen-type ligand, 1-ethyl-salicylidene-bis-ethylene diamine was synthetized using Mn(II) ions. The chemical structure was confirmed through 1H-NMR and IR spectroscopy. The antimicrobial activities of the Bis-Schiff base and its complex were tested in comparison with Ampicillin, Chloramphenicol, Tetracycline, Ofloxacin and Nystatin. Those compounds were found to be active against Gram-positive or Gram-negative bacteria, and had an anti-inflammatory effect comparable to that of Indomethacin.

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.
