Heavy metals, such as lead (Pb(2+)), are usually accumulated in human bodies and impair human's health. Lead is a metal with many recognized adverse health side effects and yet the molecular processes underlying lead toxicity are still poorly understood. In the present study, we proposed to investigate the effects of lead toxicity in cultured cardiofibroblasts. After lead treatment, cultured ca...

The present study has been conducted on Caspian Roach (Rutilus rutilus) so that the impact of different concentrations lead on blood hematological, biochemical, and immunological indicators could be investigated. The roach (Rutilus rutilus), used in this study, was 3.3±0.3 g heavy and 4±0.80 cm long in average. The fish were exposed to a low concentration of 10% LC50 and high concentration of 5...

Background: This study was undertaken to investigate whether treatment with vitamin E and N acetyl cystein protects rat sperm by inhibiting reactive oxygen species generation induced by lead (Pb) exposure. Materials and Methods: After an acclimatization period of one week, 20 Male rats were divided into 4 groups of 5 rats each. Animals within different treatment groups were maintained on their ...

Although lead pollution has long been known as a cause of poisoning, it has remained a challenge to reliably diagnose it due to its common symptoms in various diseases. In this article, we report two cases of acute loss of consciousness due to the ingestion of opium-contaminated with lead. The reported cases share patterns of symptoms similar to meningitis and encephalitis which are usual etiol...

abstract heavy metals are the important pollution which there is in the aquatic ecosystems. today, with advances in technology have increased the pollution therefore it is important to assessment the risks. the aim of this study was acute toxicity effects of mercury chloride, lead chloride and zinc chloride in silver carp fish. in this study there were 5 treatments for lead chloride and mercury...

lead poisoning has several clinical manifestations so the diagnosis may be troublesome. these manifestations consist of anemia, neurologic abnormalities, liver and biliary tract problems and abdominal pain. not only opium addiction, but also lead toxicity can cause biliary tract problems.when both etiologies occur at the same time, the diagnosis is difficult. a 46 year old opium addicted man wi...
