present study reports analgesic activity of petroleum ether, chloroform, ethyl acetate and methanolic extracts of leaves and seeds of trigonella foenum-graecum linn. (fabaceae) using hot plate method for evaluation of central analgesic activity and acetic acid induced writhing test for evaluation of peripheral analgesic activity in mice.   all the extracts of trigonella foenum-graecum showed si...

BACKGROUND The rhizome of Curcuma aeruginosa Roxb (Zingiberaceae) has been used as a traditional folk medicine for the treatment of rheumatic disorders in Bangladesh. The aim of the current study was the bioassay-guided isolation and purification of an antinociceptive principle from the methanol extract of C. aeruginosa rhizomes. METHODS The antinociceptive activity was determined using aceti...

teucrium polium is used for treatment of visceral pain in iranian folkloric medicine. in this studyantinociceptive mechanisms of t. polium hydroethanolic extract were examined by acetic acid-inducedwrithing test as a model of visceral pain in male nmri mice. to reveal the antinociceptive mechanisms ofthe extract, we examined the effects of opioidergic, serotonergic, adrenergic and histaminergic...

Primary dysmenorrhea (PD) is a common gynecological disorder. Hitherto, animal models which recapitulate clinical features of PD have not been fully established. We aimed to examine whether a pain model in mice could mimic the clinic features of PD. After pretreated with estradiol benzoate (1 mg/kg/day) intraperitoneally (i.p.) for 3 consecutive days, non-pregnant female Imprinting Control Regi...

BACKGROUND The antinociceptive effect of an aqueous extract from the leaves of Toona sinensis (TS, [A. Juss., M. Roem.]) was studied using the writhing test in mice. METHODS Different extraction fractions from TS leaf extracts (TSL1 to TSL5) were administered orally 1 h before intraperitoneal injection of acetic acid. RESULTS After treatment with TSL1, TSL2, TSL3, TSL4, and TSL5 at a dose o...

Leaf methanol extract of C. orbiculata L. was investigated for antinociceptive and anti-inflammatory activities using acetic acid writhing and hot-plate tests and carrageenan-induced oedema test in mice and rats, respectively. C. orbiculata (100-400 mg/kg, i.p.) significantly inhibited acetic acid-induced writhing and significantly delayed the reaction time of mice to the hot-plate-induced ther...

The influence of cyclooxygenase (COX) and NO synthase inhibitors on antinociceptive action of acetaminophen (ACETA) was studied in rats. ACETA increased the nociceptive threshold for both mechanical (Randall-Selitto test) and chemical stimuli (writhing test). In both models the existence of ceiling dose of ACETA was observed. Indomethacin (IND), an inhibitor preferentially acting on COX-1, as w...

OBJECTIVE Premna integrifolia Linn (Family: Verbenaceae) synonym of Premna serratifolia has tremendous medicinal value. Preliminary pharmacological studies were performed on the methanolic extract of Premna integrifolia (MEPI) bark to investigate neuropharmacological, analgesic, and anti-inflammatory activities. MATERIALS AND METHODS Neuropharmacology study was done by open field and hole cro...

Herein method for the synthesis of substituted 1,2benzoxazolone (8a-f) and 3-chloro-1,2-benzoxazole (9a-f) derivatives has been described. A new scheme has been adapted for the construction of 1,2benzoxazole ring from salicylic acid and its derivatives which leads to the formation of series of 5,6 and 7 substituted title compounds. Synthesized compounds were characterized by IR, 1 H-NMR and Mas...
