In short-term in vivo experiments, liver growth and regression in mice with high (C3H/He), intermediate (B6C3F1) or low (C57BL/6J) susceptibility to hepatocarcinogenesis was compared. Liver growth was induced by dietary administration of phenobarbital (PB; 750 ppm) or nafenopin (NAF; 500 ppm). PB or NAF treatment for 7 days produced moderate increases of liver DNA (15% or 25-28%, respectively) ...

objective(s) opioid abuse is still remained a major mental health problem, a criminal legal issue and may cause ischemic brain changes including stroke and brain edema. in the present study, we investigated whether spontaneously withdrawal syndrome might affect stroke outcomes. materials and methods addiction was induced by progressive incremental doses of morphine over 7 days. behavioral signs...

Objective(s) Opioid abuse is still remained a major mental health problem, a criminal legal issue and may cause ischemic brain changes including stroke and brain edema. In the present study, we investigated whether spontaneously withdrawal syndrome might affect stroke outcomes.

Background: Gamma-amino butyric acid (GABA) agonists have been effective in the treatment of withdrawal from benzodiazepines, sedatives and alcohol, and reducing the craving for cocaine. Valproate is a GABAergic drug effective in the treatment of neuropathic pain and also in withdrawal from benzodiaepines, sedatives, and alcohol. The purpose of this double-blind trial was to evaluate the ef...

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 visce...

introduction: it has been shown that orexin peptides have a role in opioid withdrawal behaviors. orexin-expressing neurons that are present in the hypothalamic nuclei send dense projections to the locus coeruleus (lc). withdrawal syndrome is temporally associated with hyperactivity of lc neurons. however, lc neurons do not show withdrawalinduced hyperactivity in the brain slices from morphine-d...

Objective(s): Ethanol withdrawal following chronic use, is an important challenge clinically. In this study, the effect of clavulanic acid was evaluated on the symptoms of ethanol withdrawal in rats. Materials and Methods: Alcohol dependence was induced by the gavage of ethanol (10% v/v, 2 g/kg), twice daily for 10 days. Clavulanic acid ...

in the present study, interactive effects of d1 and d2 dopamine receptors antagonists and different periods of lithium pretreatment on morphine dependence in mice have been investigated. this study was designed to investigate whether the hypothesis that lithium and dopaminergic mechanisms via their effects on phosphoinositide pathways and calcium flux could influence morphine withdrawal respons...

background: morphine and lidocaine are known to influence the perception of pain. the present study sought to determine the influence of local administration of morphine on lidocaine-induced analgesia in morphine non-dependent (mnd), morphine dependent (md) and morphine withdrawal (mw) animals. methods: adult male wistar rats were divided into four groups: control, mnd, md and mw rats. lidocain...

background: agitation is an early symptom of the acute opioid withdrawal syndrome in addicts that may start by inappropriate use of naltrexone. the current drug interventions are not efficient or need critical care as well. this study compares the clinical role of midazolam and diazepam for the management of agitation due to inappropriate use of naltrexone. materials and methods: in this double...
