Objective: Opuntia humifusa (O. humifusa) Raf. has been used for the prevention and treatment of rheumatoid arthritis, inflammation, and cancer. Our study was designed to unveil the anti-nociceptive and anti-inflammatory effects of the methanolic extract of O. humifusa Raf stem (OHS).  Material and Methods: The anti-nociceptive effect was measured by hot plate, acetic acid-induced writhing, and...

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 ...

methanolic extract of solanum trilobatum linn. (mest) belonging to the family of solanacea was evaluated by hot plate and acetic acid induced writhing methods to assess its analgesic activity. the extract was also evaluated for its anti-inflammatory activity by subjecting into carrageenan, and cotton pellet induced granuloma tests for its effect on acute and chronic phase inflammation models in...

The methanolic bark extract of Mimusops elengi was investigated for its possible analgesic and neuropharmacological activities on mice at the doses of 100mg/kg, 200mg/kg and 400mg/kg body weight. For the evaluation of analgesic activity, tail immersion and acetic acid induced writhing tests were used. The neuropharmacological activity of the extract was screened using hole cross and open field ...

The writhing number of a curve in Euclidean 3-space, introduced by Călugăreanu (1959-61) and named by Fuller (1971), is the standard measure of the extent to which the curve wraps and coils around itself; it has proved its importance for molecular biologists in the study of knotted duplex DNA and of the enzymes which affect it. The helicity of a vector field defined on a domain in Euclidean 3-s...

The acetic acid and phenyl-p-benzoquinone are easy and fast screening models to access the activity of novel candidates as analgesic drugs and their mechanisms. These models induce a characteristic and quantifiable overt pain-like behavior described as writhing response or abdominal contortions. The knowledge of the mechanisms involved in the chosen model is a crucial step forward demonstrating...

Cochlopermum tinctorium A. Rich. (Cochlospermaceae) is a commonly used medicinal plant in the West Africa sub-region for the management of various conditions including pain and inflammatory conditions. In the present study, we report the analgesic and anti-inflammatory activities of the aqueous methanol leaf (20-80 mg/kg), root (7.5-30 mg/kg), and root bark (20-80 mg/kg) extracts of the plant. ...

The potency of piperine as anti inflammatory and analgesic were investigated. Piperine was evaluated for antiinflammatory effect by carrageen-induced rat paw edema. Sprague Dawley Rats were divided into the control groups were given saline perorally, piperine groups received doses of 2.5; 5 and 10 mg/kg piperine (peroral) respectively. This was followed by the administration of 1 % caragenin th...
