We used the hot plate test and the formalin test to evaluate the antinociception of choline after i.c.v. or i.v. administration. The analgesic mechanism of choline was also studied. The response latency of mice was significantly prolonged in the hot plate test after choline (90-120 mug/animals) i.c.v. administration in a dose-dependent manner. Pretreatment with methyllycaconitine citrate (MLA),...

BACKGROUND Preemptive analgesia is an antinociceptive treatment that prevents central sensitization. Antinociceptive effects of diclofenac are well-known. The aim of this study was to investigate preemptive analgesic effects of intraperitoneally administrated diclofenac, before and after acute and inflammatory induced pain in rat model. METHODS Forty eight male Sprague Dawley rats were includ...

The analgesic effect of 5fluorouracil (5-FU) was analyzed in two experimental tests in mice. Two analgesia test, writhing test and hot plate test have been performed in swiss albino mice. The tested substance used was 5-Fluorouracil, i.p. administered in doses of 10 (Lethal Dose 50/10) and 20 mg/kg body weight (bw) (Lethal dose 50/5), 1 hour before tests. In the writhing test, 5-FU has signifi ...

The present study is a designed protocol for investigation of the analgesic effect of oral and intraperitoneal (i.p.) administration of alcoholic Datura stramonium (DS) seed extract as a rich source of alkaloid substances. Male NMRI rats were divided into control and treatment groups. The treatment rats received different doses of the DS seed extract, which was prepared from alcoholic smashed s...

objective: the beneficial effects of clove on toothache have been well documented. we have also previously shown the analgesic effects of clove essential oil. the present work was done to investigate the analgesic effects of the aqueous extract of clove using hot plate test. the possible role of opioid receptors in the analgesic effects of clove was also investigated using naloxone. materials a...

PURPOSE The present study was designed to investigate the anti-nociceptive activity of ethanolic leaf extract of Trema cannabina Lour (family: Cannabaceae) in experimental animal models. METHODS The anti-nociceptive action was carried out against two types of noxious stimuli, thermal (hot plate and tail immersion tests) and chemical (acetic acid-induced writhing) in mice. RESULTS Phytochemi...

BACKGROUND Crataeva nurvala Buch.-Ham. (Family: Capparidaceae) is widely used as anti-inflammatory, contraceptive, laxative, lithotropic, febrifuge and as tonic in traditional medicine. This study evaluated the antinociceptive effect of the methanolic extract of the leaves of Crataeva nurvala (MECN). METHODS The antinociceptive activity was investigated using heat-induced (hot-plate and tail-...

Marasmius androsaceus is a medicinal fungus mainly used to treat various forms of pain in China. This study investigated the analgesic effects of an ethanol extract of M. androsaceus (MAE) and its potential molecular mechanisms. Oral administration of MAE (50, 200, and 1000 mg/kg) had significant analgesic effects in an acid-induced writhing test, a formalin test, and a hot-plate test, with eff...
