A Polyphenols-Rich Extract from Moricandia sinaica Boiss. Exhibits Analgesic, Anti-Inflammatory and Antipyretic Activities In Vivo.

ABSTRACT: In this study, the aerial parts of Moricandia sinaica were evaluated for their in vivo analgesic, anti-inflammatory and antipyretic activities. The analgesic activities were examined using acetic acid-induced writhing, the hot plate test and the tail flick method. The anti-inflammatory and the antipyretic activities were evaluated using carrageenan-induced paw edema in rats and brewer's yeast-induced pyrexia in mice, respectively. The aqueous fraction of the methanol extract (MS-3) showed to be the most bioactive among the other investigated fractions. At the dose of 500 mg/kg, the fraction (MS-3) showed a significant percentage inhibition of the carrageenan-induced edema by 52.4% (p < 0.05). In addition, MS-3 exhibited a significant inhibition of acetic acid-induced writhes by 44.4% and 61.5% (p < 0.001) at 250-mg/kg and 500-mg/kg doses, respectively. At 120 min post-treatment, the rat groups treated with MS-3 displayed statistically significant reduction in rectal temperature (p < 0.001) by 1.7 °C and 2.2 °C at 250- and 500-mg/kg doses, respectively. The phytochemical composition of the fraction (MS-3) was characterized by high-performance liquid chromatography-mass spectrometry (HPLC-PDA-MS/MS). Molecular docking studies demonstrated that the polyphenols identified in MS-3 revealed good binding energy upon docking to some target proteins involved in pain response and inflammation, such as the cannabinoid receptors CB1 and CB2, the fatty acid amide hydrolase (FAAH) and the cyclooxygenase COX-1 and COX-2 enzymes. Based on the findings from the present work, it could be concluded that the aerial parts extract of M. sinaica exerts potential analgesic, anti-inflammatory and antipyretic effects in rats.

Project description:Background Pain and inflammation are the major devastating health problems commonly treated with traditional medicinal plants in Ethiopia. Echinops kebericho M. (Asteraceae) is the one which is frequently used to treat pain and inflammation by traditional healers in Ethiopian folk medicine. However, the plant has not been scientifically evaluated for its traditionally claimed use. The present study aimed at the investigation of analgesic and anti-inflammatory activities of 80% methanol root extract of Echinops kebericho M. in mice model. Methods Successive maceration was used as a method of extraction using solvents of increasing polarity: methanol and water. After extraction of the roots with 80% hydro methanol, the crude extract was evaluated for its peripheral and central analgesic activities using acetic acid-induced writhing test and hot plate method, respectively, while its anti-inflammatory activity was evaluated using carrageenan- and formalin-induced paw edema. The extract was evaluated at 100, 200 and 400 mg/kg doses. The positive control groups were treated with ASA 150 mg/kg for writhing test, morphine 10 mg/kg for hot plat method, indomethacin 25 mg/kg and diclofenac 10 mg/kg for paw edema tests and vehicle, distilled water (10 mL/kg) treated mice were assigned as negative controls. All treatment administrations were performed orally. Results E. kebericho extract at all test doses showed statistically significant antinociceptive activity in both chemicals-induced peripheral and thermal-induced central pain in a dose dependent manner (p < 0.01 and p < 0.001). The greater analgesic activity was observed by the maximum dose of the extract (400 mg/kg) in both acetic acids-induced writhing test (57.84%) and hot plate method (69.40%). The effect of the extract was also statistically significant (p < 0.01 and p < 0.001) in both carrageenan and formalin-induced paw edema in dose dependent manner. Greater edema inhibition was observed by the highest dose (400 mg/kg) in both observations with the respective percentage values of 70.00% and 79.87%, respectively. Conclusion In general, the data obtained from the present study elucidated that the extract possessed a significant analgesic and anti-inflammatory activities and recommended for further studies.

Project description:BACKGROUND:The use of analgesic antipyretics (ANAP) in children have long been a matter of controversy. Data on their practical use on an individual level has, however, been scarce. There are indications of possible effects on glucose homeostasis and immune function related to the use of ANAP. The aim of this study was to analyze patterns of analgesic antipyretic use across the clinical centers of The Environmental Determinants of Diabetes in the Young (TEDDY) prospective cohort study and test if ANAP use was a risk factor for islet autoimmunity. METHODS:Data were collected for 8542 children in the first 2.5 years of life. Incidence was analyzed using logistic regression with country and first child status as independent variables. Holm's procedure was used to adjust for multiplicity of intercountry comparisons. Time to autoantibody seroconversion was analyzed using a Cox proportional hazards model with cumulative analgesic use as primary time dependent covariate of interest. For each categorization, a generalized estimating equation (GEE) approach was used. RESULTS:Higher prevalence of ANAP use was found in the U.S. (95.7%) and Sweden (94.8%) compared to Finland (78.1%) and Germany (80.2%). First-born children were more commonly given acetaminophen (OR 1.26; 95% CI 1.07, 1.49; p = 0.007) but less commonly Non-Steroidal Anti-inflammatory Drugs (NSAID) (OR 0.86; 95% CI 0.78, 0.95; p = 0.002). Acetaminophen and NSAID use in the absence of fever and infection was more prevalent in the U.S. (40.4%; 26.3% of doses) compared to Sweden, Finland and Germany (p < 0.001). Acetaminophen or NSAID use before age 2.5 years did not predict development of islet autoimmunity by age 6 years (HR 1.02, 95% CI 0.99-1.09; p = 0.27). In a sub-analysis, acetaminophen use in children with fever weakly predicted development of islet autoimmunity by age 3 years (HR 1.05; 95% CI 1.01-1.09; p = 0.024). CONCLUSIONS:ANAP use in young children is not a risk factor for seroconversion by age 6 years. Use of ANAP is widespread in young children, and significantly higher in the U.S. compared to other study sites, where use is common also in absence of fever and infection.
