Introduction: Topiramate is an anti-convulsant drug, which produces its effects via glutamate metabotropic receptors inhibition and/or GABA receptor excitation. In the present study, attempts were made to investigate the effects of topiramate on the tolerance to morphine-induced analgesia activity in male NMRI mice (20-30 g). Methods: Hot plate method was chosen for the study. First of all t...
Several studies have demonstrated that the electromagnetic fields produce analgesic activity. The aim of this study was to investigate the effects of extremely low frequency (ELF) electromagnetic fields (EMF) on morphine analgesia and tolerance in rats. In the study, 78 adult male Wistar albino rats (approximately 240 ± 12 g) were used. The application of 50 Hz magnetic field, each day the same...
In the present study, the effects of intra-cerebral hippocampus (CA1) injections of apomorphine D1, D2-like receptors agonists on morphine-induced place preference in male Wistar rats have been investigated. Subcutaneous administration of different dose of morphine sulphate (1, 3, 6 and 9 mg/kg) produced a dose-dependent conditioned place preference (CPP). Intra-cerebral hippocampus (CA1) admin...
Background: Cuminum cyminum fruit essential oil (FEO) dose-dependently can attenuate the expression of morphine tolerance and dependence in morphine-dependent mice. Objective: In this study, the effects of Cuminum cyminum FEO on acquisition and expression of morphine-induced conditioned place preference (CPP) in morphine-sensitized mice were studied. Methods: Repeated subcutaneous (s.c.) adm...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
INTRODUCTION Consumption of codeine can lead to positive urine test for morphine in athletes. Morphine is classified as a prohibited doping drug while Codeine is not. Morphine/codeine ratio is used in forensic medicine to distinguish the consumption of codeine from abuse of morphine and other narcotics. CASE PRESENTATION We present an athlete with positive urine test for morphine with a histo...
building on previous studies on the effectiveness of different types of written corrective feedback, the present study aimed at investigating whether direct focused corrective feedback and direct unfocused corrective feedback produced any differential effects on the accurate use of english articles by efl learners across two different proficiency levels (low and high). in current study, the par...
opiates such as morphine are one of the most effective classes of medication prescribed to treat both acute and chronic pain.they act to suppress pain through mu-receptor activation on primary afferent nerve fibers, dorsal horn neurons and supraspinal pain center neorons. when morphine is administered epidurally, it diffuses to the cord substance, producing analgesia [1],the aim of this study w...
The antinociceptive and ventilatory effects of morphine and other opioid agonists were determined in three rhesus monkeys during a period of morphine maintenance, as well as before and after the chronic exposure to morphine. Before the onset of the daily dosing regimen, morphine increased tail-withdrawal latencies from 50 degrees C water, with an ED50 of 6.4 +/- 2.1 mg/kg. Daily injection of 3....
