Carum copticum from Apiaceae family has several biological effects including analgesic, anti-inflammatory, anxiolytic and antispasmodic activities. This study was designed to evaluate its effect on suppression of naloxone-induced morphine withdrawal signs. Hydroalcoholic and polyphenolic extracts were prepared according to the standard methods. Male mice (25-30 g) were made dependent by subcuta...

in the present study, interactions between lead exposure with nitric oxide precursor (l-arginine) or nitric oxide synthase (nos) inhibitor (l-name) on naloxone-induced jumping and diarrhea in morphine-dependent mice were examined. chronic lead acetate (0.05%) exposure altered naloxone-induced jumping and diarrhea in mice. jumping was decreased after 7 days and was unchanged 14 and 28 days after...

introduction: previous studies have suggested that plants avena sativa, hypericum perforatum, passiflora incarnata and lavandula officinalis can affect nervous system and reduce neural excitability and pain. the aim of this study was to evaluate the effect of a mixture of these four plant’s alcoholic extract on morphine withdrawal symptoms. methods: experiments were performed on four animal gro...

Naloxone is a non-selective, short-acting opioid receptor antagonist that has a long clinical history of successful use and is presently considered a safe drug over a wide dose range (up to 10 mg). In opioid-dependent patients, naloxone is used in the treatment of opioid-overdose-induced respiratory depression, in (ultra)rapid detoxification and in combination with buprenorphine for maintenance...

OBJECTIVE The goal was to determine whether withdrawal from sugar can cause signs of opioid dependence. Because palatable food stimulates neural systems that are implicated in drug addiction, it was hypothesized that intermittent, excessive sugar intake might create dependency, as indicated by withdrawal signs. RESEARCH METHODS AND PROCEDURES Male rats were food-deprived for 12 hours daily, i...

In the present study, interactions between lead exposure with nitric oxide precursor (L-arginine) or nitric oxide synthase (NOS) inhibitor (L-NAME) on naloxone-induced jumping and diarrhea in morphine-dependent mice were examined. Chronic lead acetate (0.05%) exposure altered naloxone-induced jumping and diarrhea in mice. Jumping was decreased after 7 days and was unchanged 14 and 28 days after...

BACKGROUND Long-term exposure to opiates induces physical dependence; however, the neurobiological mechanisms of this phenomenon are not completely clear. The purpose of this study was to evaluate the effects of systemic and intracerebroventricular (icv) administration of selegiline (a selective inhibitor of monoamine oxidase B) on the morphine withdrawal syndrome in rats. METHODS To this aim...

Physical dependence on morphine is evidenced by the withdrawal syndromes, including body weight loss, which are induced by the discontinuation of morphine exposure or by the treatment with naloxone, an opioid receptor antagonist. The present study was designed to examine whether the elevation of serum corticosterone (SCS) level induced by naloxone-precipitated morphine withdrawal was a useful i...
