introduction: some studies indicate changes in the level of thyroid hormones in addicted people. also, there are some reports concerning the modulation of hypothalamus-hypophysis-thyroid axis in the context of morphine addiction. in the present study, the effects of thyroid gland activation via the acute and chronic administration of levothyroxine on morphine withdrawal syndrome were investigat...
The present study focused on the evaluation of a role of opioid system in nicotine-induced antinociception and physical dependence in mice. The results indicate that nicotine (3 mg/kg) produced a significant antinociception in the hot plate test. Additionally, the opioid receptor antagonist naloxone (0.5 and 1 mg/kg), dose-dependently attenuated this effect. Our second experimental protocol con...
Opioid antagonists can be classified as inverse agonists and neutral antagonists. In the opioid-dependent state, neutral antagonists are significantly less potent in precipitating withdrawal than inverse agonists. Consequently, neutral opioid antagonists may offer advantages over inverse agonists in the management of opioid overdose. In this study, the relative potency of three opioid antagonis...
In the present study, the effects of intra-locus coeruleus injection of a dopamine D(1) receptor agonist (SKF38393) on naloxone-induced withdrawal signs of morphine-dependent rats were examined. Twenty different withdrawal signs were assessed. The total withdrawal score was calculated and used as an index of withdrawal intensity for comparison. The D(1) agonist and antagonist were injected 15 a...
Acute morphine withdrawal is considered to be the physical manifestation of dependence, emerging when morphine administration is stopped or after the administration of an opiate antagonist, such as naloxone. Gabapentin, which is an antiepileptic, agent, enhances the analgesic effect of morphine in healthy volunteers, but its effect on morphine dependence and withdrawal signs has not determined ...
BACKGROUND Herbal medical compounds and their major constituent have been used in the management and treatment of opioid withdrawal syndrome and pain. This study was carried out to clarify the effect of curcumin, the major compound of turmeric, on morphine withdrawal syndrome in mouse model and its possible mechanisms of pain relieving activity by assessing in writhing test as a model of viscer...
background and aims: safflower (carthamus tinctorius l.)from asteraceae family has different biological activities including analgesic, antidepressant, anti-inflammatory, antispasmodic and neuroprotective effects. this study designed to evaluate its effect on naloxone -induced morphine withdrawal signs. methods: in this experimental study, male nmri mice (25-30 g) were randomly divided into 5 g...
AIM To study correlation between inhibitions of naloxone-precipitated withdrawal jumps and nitric-oxide synthase (NOS) activity by agmatine. METHODS NOS activities in mouse brain were measured by determination of concentration of [3H]citrulline, the product of [3H]arginine. RESULTS Agmatine inhibited NOS activity in naive and morphine-dependent mouse cerebellum, forebrain, and thalamus in s...

Abstract Regarding the proven anticonvulsant effect of Zhumeria majdae essential oil (ZMEO) in previous studies we were prompted to investigate ZMEO effects on tolerance morphine and withdrawal syndrome. Tolerance was induced mice by subcutaneous injection 2.5 mg/kg for 4 days. Subsequent doses (20 mg/kg) used study expression development tolerance. Clonidine as standard drug inhibit syndrome s...
