Stem bark of Nyctanthes arbor-tristis Linn. was extracted in methanol to evaluate their analgesic and anti-inflammatory activities. The analgesic activity was determined on Wistar albino rats by hot plate method, tail flick assay, and tail immersion method using Morphine sulphate as standard drug at a dose of 5 mg/kg of body weight and the results were expressed as mean increase in latency afte...

Purpose: To investigate the anti-inflammatory and analgesic activities of the Amorphophallus Bulbifer in Wistar rats and mice. Methods: The anti-inflammatory activity of the hydroalcohol extract of A. bulbifer whole plant at dose levels of 100 and 200 mg/kg p.o. in rats was determined with a plethysmograph paw volume difference of the animals preand post-treatment. Ibuprofen (10 mg/kg) was empl...

phencyclidine (1-(1-phenylcyclohexyl) piperidine, pcp, i) and ketamine (2-o-chlorophenyl-2-methylaminocyclohexan, ii) have shown analgesic effects. some of its derivatives were synthesized and their biological properties have been studied. in this study, a new derivative of pcp, (1-[1-(3-methoxyphenyl) (tetralyl)] piperidine, pcp-och3-tetralyl, iii) was synthesized and the acute thermal pain of...

introduction: nucleus cuneiformis (ncf), as part of descending pain inhibitory system, cooperates with periaqueductal gray (pag) and rostral ventromedial medulla (rvm) in supraspinal modulation of pain. cannabinoids have analgesic effects in the pag, rvm and ncf. the transient receptor potential vanilloid type 1(trpv1) can be activated by anandamide and win55,212-2 as a cannabinoid receptor ago...

Background. Ficus hispida is traditionally used in the ailment of pain, inflammation, and neurological disorders. The present study set out to evaluate the in vivo antinociceptive, anti-inflammatory, and sedative activity of the ethanol extract of Ficus hispida bark (EFHB). Methods. The antinociceptive activity of EFHB was evaluated by using acetic acid induced writhing, formalin, hot plate, an...

the selected parts of four medicinal plants, achillea millefolium, hibiscus rosasinensis, linum usitatissimum and pluchea lanceolata were extracted in absolute methanol to determine their analgesic activity. analgesic activity was assessed on intact mice by tail flick latency via the tail immersion method. the analgesic activities of these plant extracts were compared with acetylsalicylic acid ...

Treatment of mouse tail skins with hexachlorophene (1.25% w/v) in abso­ lute methanol or 70% isopropanol suppressed Schistosoma mansoni infections by more than 95% even when the application was performed up to three days prior to exposure to cercarial suspensions by tail immersion. Treatment with concen­ trations of 0.313% or higher one day prior to exposure provided at least 98% protection whe...

Hydroxydihydrocarvone (HC) is a synthetic intermediate obtained by hydration of the natural compound (R)-(-)-carvone. The aim of the present study was to investigate the possible anti-inflammatory activity of orally administered HC. Toxicity, motor coordination, tail immersion test, as well as carrageenan-induced paw edema and myeloperoxidase (MPO) activity or peritonitis were all evaluated in ...

AIM This paper is focused on the investigation the effects of two polymeric matrices for indomethacin in cutaneous pain models in mice. There were used two different co-polymers polyhydroxyethyl methacrylate and undecan, polymerization reactions being conducted under nitrogen, at 80 degrees C. MATERIAL AND METHODS The experiments were carried out on white Swiss mice (20-25 g), divided into 6 ...

We investigated the role of capsaicin-sensitive small diameter fibers in the development of the thermal and mechanical allodynia in a new rat model for neuropathic pain, produced by transecting some but not all of the nerves innervating the tail. Capsaicin (50 mg/kg, s.c.) injected neonatally prior to the nerve injury produced thermal hypoalgesia in the tail the degree of which was variable acr...
