Signs and symptoms of D PH toxicity were seen in an epileptic child who had received DPH and MP concurrently. In the absence of liver and kidney disease and any intercurrent infection, and with the patient's recovery following the withdrawal of DPH, it appears that drug-drug interaction is the most logical explanation for DPH intoxication.

cannabis is one of the most banned drugs in the world. cannabinoid-induced dependence or withdrawal signs are indicated by the result of complex molecular mechanisms including upstream protein kinases (pks), such as an extracellular signal regulated kinase1/2 (erk1/2) and downstream glycogen synthase kinase-3β (gsk-3β), which lead to neuronal plasticity. in this study, we examined the protectiv...

One diagnostic criterion of alcohol dependence is the appearance of a withdrawal syndrome when alcohol consumption ceases. Researchers have used various animal models, including isolated brain cells, slices of brain tissue, and intact animals, to study the mechanisms and manifestations of withdrawal. Results from these experimental studies have demonstrated that many consequences of withdrawal ...

BACKGROUND Thymus species are well known medicinal plants which the previous studies suggested the involvement of the opioid system in them. OBJECTIVES This study aimed to investigate the effects of methanolic extract and essential oil of aerial parts of Thymus daenensis (TD), an endemic aromatic medicinal plant of Iran, on morphine withdrawal syndrome in mice. MATERIALS AND METHODS Experim...

Tolerance and dependence are two main problems that have limited morphine administration. There are several reports on the effect of some medicinal plants on morphine-induced tolerance and dependence. In this study we investigated the effect of Ferula persica (FP) extract on modulation of withdrawal syndrome sign (WSS). For this purpose, male Albino mice (25-30 g, n=30) were used. Morphine was ...

Effect of Otostegia persica on naloxone-induced morphine withdrawal syndrome was studied in male mice. Dependence was induced using daily subcutaneous injections of morphine for three days. Morphine was injected to mice at doses of 30 and 45mg/kg on day 1 and 60 and 90mg/kg on day 2 (8:00 am and 6:00 pm). On day 3, morphine (90mg/kg) was injected 1h before oral administration and 1.5h before in...

BACKGROUND Some drugs of abuse down regulate the expression of cystine/glutamate (xCT) antiporter in the nucleus accumbens (Acb) after extinction or withdrawal. The altered level of xCT exchanger in Acb, a structure involved in ethanol reinforcement, may contribute to the pathological glutamatergic signaling, linked to addiction. We hypothesized that the expression of xCT may be changed in Acb ...

An important factor contributing to the high relapse rates among smokers is nicotine withdrawal symptoms. Multiple studies suggest that decreased dopamine release in nucleus accumbens plays a key role in withdrawal. However, recent reports showed that long-term nicotine exposure itself also decreases accumbal dopamine release, suggesting that additional mechanisms are involved in withdrawal. He...

CONTEXT Because anticipation of death is common within the intensive care unit, attention must be paid to the prevention of distressing signs and symptoms, enabling the patient to die peacefully. In the relevant studies on this subject, there has been a lack of focus on measuring determinants of comfort in this population. OBJECTIVES To evaluate whether dying without distressing signs after t...
