conclusions our findings support the role of nmdars in pregabalin antinociception, because the nmdar agonist, unlike the antagonist, decreased the antinociceptive effect of pregabalin, even if tail flick is not an adequate pain assessment method in this regard. background pregabalin as a new anticonvulsant has been used in different pain treatments. objectives the aim of this study was to inves...

Aim: The objective of the current study is to investigate the antinoceptive effect of Pentazocineon streptozotocininduced diabetic rats. Methods: Diabetes mellitus was induced by using streptozotocin, dose of 50mg/kg body weight through lateral tail vein injection. After 48 hours, rat with blood glucose range of 200–300mg were used for experiment. NPH – insulin was given by subcutaneous injecti...

Studies have shown that noxious cutaneous stimulation engages physiologically different antinociceptive systems to inhibit a spinal reflex, tail withdrawal from radiant heat. Two experiments are reported that examine the relationship between the inhibition of the tail-flick response and brain-mediated responses to nociception. The induction of a spinally mediated antinociception was accompanied...

BACKGROUND Neurologic deficits after apparent intrathecal injection of 3% Nesacaine-CE intended for epidural administration created concern about the potential toxicity of chloroprocaine and the preservative sodium bisulfite. Although bisulfite-free formulations of chloroprocaine were subsequently introduced into clinical practice, the relative toxicities of this anesthetic and preservative wer...

Purpose: Buprederm-Buprenorphine transdermal delivery system (BTDS) was developed for the treatment of post-operative and chronic pains. This study examined the relationship between the plasma concentration of buprenorphine and its analgesic effect (tail flick test) in order to assess the usefulness of pharmacokinetic-pharmacodynamic (PK-PD) modeling in describing this relationship. Methods: Af...

BACKGROUND The current study investigated whether racemic bupivacaine and its S(-)- and R(+)-enantiomers, levobupivacaine and dextrobupivacaine, differ in somatic and visceral antinociception and neurotoxicity when administered intrathecally in rats. METHODS In experiment 1, rats intrathecally received 15 microl saline or 0.125, 0.25, 0.5, or 1% bupivacaine, levobupivacaine, or dextrobupivaca...

ETHNOPHARMACOLOGICAL RELEVANCE Leaf extracts of Buddleja globosa (Buddlejaceae) are used in Chilean folk medicine for wound healing. The anti-inflammatory (topic and per os), analgesic (per os) effects and the antioxidant activity of Buddleja globosa were for the first time reported by us. AIM OF THE STUDY Assess the antinociceptive activity of the methanol sequential and global extracts usin...

BACKGROUND Diabetes mellitus (types 1 and 2) leads to secondary complications such as neuropathy, which reduce a patient's quality of life. Apelin and its receptor, APJ, have been shown to have antinociceptive effects and to decrease blood glucose levels. OBJECTIVES The present experimental study was conducted in Iran and investigated the role of apelin, which is used to manage type 1 diabete...
