BACKGROUND Dialium guineense is a medicinal plant used by some communities of Enugu-Ezike in Enugu State, Nigeria for treatment of fever, headache and other diverse ailments. OBJECTIVES The present study evaluated the analgesic activity of the methanolic stem bark extract of the plant. METHOD Acetic acid-induced abdominal constriction or writhing, tail immersion and hot plate analgesic mode...

Genetic deletion of pleiotrophin (PTN) impairs spinal nociceptive transmission suggesting that this heparin binding growth factor could play roles in acute pain processing. Despite the high functional redundancy between PTN and midkine (MK), the only other member of this family of growth factors, we now demonstrate that genetic inactivation of MK does not alter acute nociceptive transmission si...

BACKGROUND Persicaria hydropiper (Linn.) Delarbre is a common plant of Polygonaceae family commonly called Bishkatali in Bangladesh. Leaves of the plant are traditionally used in the treatment of rheumatic pain, gout, and skin diseases such as ringworms, scabies, boils, abscesses, carbuncles, bites of snakes, dogs or insects. This study evaluated the antinociceptive effect of the methanol extra...

background: matricaria chamomilla (chamomile) is a herb used to treat various human illnesses. the present study was conducted to investigate the effects of chamomile extract on spermatozoon quality, serum levels of estradiol and testosterone, and sperm tail length in male adult rat .   methods: male sprague-dawley rats received extract of chamomile (400 mg/kg once daily, orally) during an 8-we...

OBJECTIVE The present study was undertaken to evaluate the antinociceptive effects of an ayurvedic polyherbal formulation in rats and mice employing the tail immersion test and acetic acid-induced writhing test, respectively. MATERIALS AND METHODS With the tail immersion method, rats received two different doses (270 and 405 mg/kg BW, p.o.) of a formulation, pethidine (5.4 mg/kg BW, p.o.) as ...

The antinociceptive activity of the methanolic extract of the leaves of Feronia limonia Linn. (Family Rutaceae) was investigated using acetic acid-induced writhing model and tail flick test in swiss albino mice. The extract produced about 26.01% ( p< 0.01), 39.88% ( p< 0.01) and 57.07% (p< 0.01) writhing inhibition at the dose of 100, 200 and 400 mg/kg of body weight respectively, which was com...

Oxazoline is one of the 5 membered heterocycle ring can be synthesized in many ways and various activities like analgesic, antimicrobial and antidiabetic activity are well documented. In the present study analgesic activity screened by tail flick and tail immersion model.The synthesized compounds are ideally characterized spectrophotometrically. Chlorinated and methoxylated oxazolines found to ...

The analgesic effect and possible mechanism(s) of action of 50-200 mg/kg of the aqueous seed extract of H. umbellata (HU) were investigated in different experimental models of analgesia using the tail flick, tail immersion, acetic acid-induced writhing tests and formalin-induced algesia. Oral pre-treatment with 50-200 mg/kg of HU caused significant and dose related analgesic effect in the treat...

Experiments were carried out with Sw albino mice and it was concluded that the percutaneous route via abdominal skin was significatively more efficient than tail immersion method and subcutaneous infection; the subcutaneous injection was significatively more efficient than the percutaneous infection through the tail; this latter and the intraperitoneal injection, resulted in similar infections,...

  Objective(s): The aim of study was to investigate the antinociceptive effect of intracerebroventricular (ICV) microinjection of Origanum vulgare (ORG) extract and possible involvement of opioid receptors.   Materials and Methods: Cannula was inserted into left ventricle of male rats. Five days after surgery Tail Flick Latency (TFL) was measured after ICV microinjection of, ORG (1, 3 and 6 μg ...
