Metal ions such as iron, zinc, and manganese are essential to metabolic functions, protein synthesis, neurotransmission, and antioxidant neuroprotective mechanisms. Conversely, non-essential metals such as mercury and lead are sources of human intoxication due to occupational activities or environmental contamination. Essential or non-essential metal accumulation in the central nervous system (...

abstract background: acute opium intoxication is one of the most common causes of poisoning in children in iran. although most cases are accidental, traditional misuse of opium for symptomatic therapy of various childhood diseases also contributes to high rate of opium intoxication in iran. cases: here, we report two cases of opium intoxication in infants resulted from transdermal application o...

Introduction: Alcohol abuse is one of the grave social and medical problems in many countries, including Russia. not only negatively affects health, family relationships, but also a person’s performance. Hangover, which negative consequences alcohol intake, complex neurological somatic symptoms that occur when ethanol almost completely metabolized to acetaldehyde. This condition, despite severi...

Evidence implicating oxidative stress in toxicity during lead intoxication in vivo has opened new avenues for investigation of the mechanisms of lead-induced immunosuppression. The current study explores the possibility that lead-induced oxidative stress contributes to the immunosuppression observed during lead poisoning. Fisher 344 rats were exposed to 2,000 ppm lead acetate in their drinking ...

The hypothesis that phenytoin may antagonise the antidiuretic effect of carbamazepine has been examined by comparing the free water clearance response to a standard water load in 36 patients stabilised on different drug regimes. The diuretic response to the water load was significantly greater in patients receiving chronic treatment with carbamazepine and phenytoin in combination than in matche...

The present study tested the effect of the combined use of alcohol and water on driving-related cognitions and behavior. Seventy-four female students performed a driving simulator task after having consumed alcohol or a placebo. Additionally, half of the participants consumed 0.5 liter of water. It was hypothesized that combining alcohol and water could lead to an underestimated perceived intox...

John Snow was one of the founders of epidemiology. Already convinced of the value of pure water, he analysed the distribution of cholera cases in the 1848 epidemic in relation to the purity of the water supply in London. His hypothesis that cholera was spread by contaminated water was tested by the 'Broad Street' epidemic of 1854. Snow quickly traced the water used in the houses affected by cho...
