Results: TT treatment of diabetic rats reduced pain score only in chronic phase of the formalin test (p<0.05). Meanwhile, SS administration significantly reduced pain score only at chronic phase of the test (p<0.05). Regarding hot tail immersion test, diabetic rats showed a significant reduction in tail flick latency as compared to control ones (p<0.05). Although TT treatment of diabetic rats i...

This study investigated the role of K(ATP) channels in morphine-induced antinociception and hepatic oxidative stress in acute and inflammatory pain. The K(ATP) channel modulators (K(ATP) channel opener, diazoxide 100 mg/kg, p.o, and K(ATP) channel blocker, glibenclamide, 3 mg/kg i.p.) were administered with morphine (80 mg/kg, i.p.). Antinociception was assessed by the tail-flick and formalin t...

In this study we used the chronic (formalin test) and acute (tail flick) pain models of rats for evaluation of probable analgesic and anti-inflammatory effect of Sambucus ebulus (Se) rhizome extract. Sodium salicylate (SS) was used as a positive control. A total of 300 mg/kg of SS (i.p.) had no effect on tail flick latency, while 100 and 200 mg/kg i.p. of extract increased this latency (P < 0.0...

We have studied the involvement of the N-methyl-D-aspartate receptor (NMDAR) glycine site and the strychnine-sensitive glycine receptor (GlyR) in the ventrolateral periaqueductal gray (VL-PAG) on nociceptive behavior (tail flick) and pain-related changes on neuronal activity in the rostral ventromedial medulla (RVM). Glycine or D-serine increased the tail-flick latency, reduced OFF-cell pause, ...

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...

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...

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...

Previous studies showed the role of basolateral amygdala (BLA) in cannabinoid-induced antinociception. Furthermore, the nucleus accumbens (NAc) plays an important role in mediating the suppression of pain in animal models. The present study extended the role of dopamine receptors within the NAc in antinociceptive effect of cannabinoid receptor agonist, WIN55,212-2, microinjected into the BLA fo...
