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...

Objective: Vitex agnus-castus (VAC) and its essential oil have been traditionally used to treat many conditions and symptoms such as premenstrual problems, mastalgia, inflammation, sexual dysfunction, and pain. In this study, the effects of essential oil extracted from Vitex agnus-castus (EOVAC) leaves were investigated in three behavioral models of nociception in adult male Wistar rats. Materi...

We present the case report of a 13-month-old Caucasian toddler with symptoms of loss of consciousness, central cyanosis and uncontrolled movements of the upper limbs while taking a warm bath. The diagnosis of hot water epilepsy was supported by an ictal EEG. Hot water epilepsy, also known as bathing epilepsy or water-immersion epilepsy is, in the Caucasian population, a rare form of benign epil...

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 ...

OBJECTIVE Magnesium is an endogenous voltage-dependent NMDA receptor-channel blocker and ketamine is a non-competitive NMDA receptor antagonist. Magnesium may potentiate the effect of ketamine in analgesia and anaesthesia, but may also interact in an opposing manner. This study aimed at evaluating type of the interaction between magnesium sulphate and ketamine administered systemically in rats ...

The aim of the present study was to determine if phenobarbital affects the nociception threshold. Systemic (1-20 mg/kg) phenobarbital administration dose dependently induced hyperalgesia in the tail-flick, hot-plate and formalin tests in rats and in the abdominal constriction test in mice. Formalin and abdominal constriction tests were the most sensitive procedures for the detection of hyperalg...

Fruits of Phoenix sylvestris Roxb. (Arecaceae) are used to treat back pain, toothache, headache, arthritis, nervous debility and as sedative. The aim of this study was to evaluate the antinociceptive and neuropharmacological activities of methanol extract of P. sylvestris fruit pulp (MEPS). The antinociceptive activity of MEPS was evaluated by heat-induced (hot plate, tail immersion test) and c...

In this study, we examined whether Sprague-Dawley rats obtained from two different vendors, Harlan and Sasco, differ with respect to the types of alpha-2 adrenoceptors in the spinal cord that mediate antinociception. This hypothesis was tested using two alpha-2 adrenoceptor agonists, dexmedetomidine and ST-91, which are relatively selective for alpha-2A and alpha-2B adrenoceptors, respectively,...

BACKGROUND Opuntia elatio Mill is a xerophytic plant with potentially active nutrients. It is traditionally appreciated for its pharmacological properties; however, the scientific information on this plant is insufficient. OBJECTIVE The present study evaluates the antinociceptive and anti-inflammatory action of prickly pear. MATERIALS AND METHODS Writhing and tail-immersion tests were carri...
