background ascorbic acid is amongst important water-soluble vitamins and when used orally in high-doses it has been observed to relieve pain and reduce opioid use in patients. however no controlled trial has compared the antinociceptive effects of ascorbic acid with other analgesic groups on animal models, and investigated the involved mechanisms. objectives in the present study, the antinocice...

Acute morphine withdrawal is considered to be the physical manifestation of dependence, emerging when morphine administration is stopped or after the administration of an opiate antagonist, such as naloxone. Gabapentin, which is an antiepileptic, agent, enhances the analgesic effect of morphine in healthy volunteers, but its effect on morphine dependence and withdrawal signs has not determined ...

Objectives: Aim of the present work was to investigate the anti-inflammatory, analgesic and antiulcer effects of red seaweed Porphyra vietnamensis (P. vietnamenis). Materials and Methods: Aqueous (POR) and alcoholic (PE) fractions were successfully isolated from P. vietnamenis. Further biological investigations were performed using a classic test of paw edema induced by carrageenan, writhing in...

Chalcone (1,3-diarylprop-2-en-1-one) derivatives have been introduced as selective cyclooxygenase-2 inhibitors. In the present study, anti-nociceptive and anti-inflammatory effects of eight novel compounds were evaluated in male mice and Wistar rats by using the writhing and formalin-induced paw edema tests respectively. The activities of the compounds were compared with celecoxib as a referenc...

Ascaris lumbricoides is one of the most common human helminthic diseases worldwide. On ultrasound, it is seen as linear non-shadowing echogenic structures with target appearance in cross section, and the live worm may show writhing movements in real time. On barium meal follow through, it appears as radiolucent tubular filling defects within the bowel lumen. Though not sensitive, direct real-ti...

Commercially available Aztec marigold (Tagetes erecta) flower extract (Af.Cr) was evaluated for the in vitro antioxidant activity and in vivo analgesic effect on acetic-acid-induced abdominal writhing. The results revealed the presence of pronounced antioxidant potential in Aztec marigold flowers and a dose-dependent (100 and 300 mg/kg) analgesic effect. The antioxidant and analgesic activities...

the ethanolic extract of wedelia chinensis (eewc) belonging to the family of asteraceae was evaluated by hot plate and acetic acid induced writhing methods to assess its analgesic activity. the extract was also evaluated for its by using on carrageenan, mediators such as histamine and serotonin induced paw oedema, and cotton pellet induced granuloma tests for its effect on acute and chronic pha...

croton guatemalensis lotsy (cgl), known as “copalchi” in chiapas, mexico, is used for the treatment of fever, abdominal pain and malaria and also as a remedy for chills and for treating rheumatism. the aim of this study was to evaluate whether aqueous extracts from the bark of this plant possesses indeed antinociceptive properties by using two different animal models of nociception, the acetic ...

The ethanolic extract of the leaves of Tamarindus indicus was investigated for its anti inflammatory and analgesic actions. The anti inflammatory activity was studied using carrageenin induced hind paw edema in rats and analgesic activity using chemical writhing test and tail clip method in mice and tail flick method yin rats. Test drug exhibited significant dose dependent anti inflammatory and...
