background: due to the increasing pollution of water resources, this study was carried out for evaluation of water quality pollution indices for monitoring of heavy metals (as, zn, pb and cu) contamination in ghahavand plain, hamadan province, western iran during spring and summer 2012. methods: totally, 20 ground water wells were chosen randomly. the samples were filtered (0.45 μm) and maintai...

Introduction: Hepatitis B and C are major health problems in many countries, especially developing areas. The frequency of hepatitis B is less than 0.8%, and chronic hepatitis C is less than 0.5% in the general population of Yazd in the center of Iran. Large vehicle drivers have some risk factors for acquiring hepatitis B and C infection. This is important because viral hepatitis complications,...

OBJECTIVE The potential toxic effects on the immune system exerted by occupational and accidental environmental exposures and underlying molecular regulatory mechanisms involved in the etiology and progression of infectious diseases are now being characterized. The Bhopal gas tragedy is undoubtedly one of the worst industrial disasters in the history of mankind. After 25 years of accidental exp...

Immunoglobulin therapy has a rich history of use in preventing and treating infectious diseases; however, clinical data on the efficacy of immunoglobulin is lacking for many infectious diseases. Immunoglobulin therapy is routinely used in postexposure prophylaxis for bacterial infections, including tetanus, botulism, and diphtheria, and viral infections, including hepatitis A and B and varicell...

Amiodarone is a commonly used anti-arrhythmic in elderly patients. Abnormal liver function is frequently reported with its use but clinically symptomatic disease is rare. Hepatomegaly, cholestasis, acute hepatitis and rarely fulminant liver failure have been recorded [1, 2], however amiodarone toxicity presenting with cirrhosis is exceedingly rare. Toxic effects of amiodarone are well described...

The treatment of woodchuck hepatitis virus infections with 1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)-5-iodocytosine (FIAC) and 1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)-5-methyluracil (FMAU), given intraperitoneally, caused complete and permanent decrease of serum virus endogenous DNA polymerase and viral DNA in all treated woodchucks but was associated with severe toxicity. By contra...

Patients presenting with elevated transaminases and jaundice are routinely tested for viral, autoimmune and drug etiologies. Acetaminophen (APAP) toxicity is a common and treatable cause of toxic hepatitis and elevated APAP levels in the setting of acute liver injury usually imply that acetaminophen is a primary contributor to the injury. Rare case reports, however, have described elevated leve...

A anaemia is a life threatening blood disorder that affects a large number of children each year in India. Exposure to toxic agents like benzene, radiation and viruses like hepatitis A have been implicated in its aetiology. The incidence in developing countries is far higher compared to developed countries. Investigating a child with pancytopenia is more complex than that of an adult as numerou...

Chronic hepatitis C virus infection can cause liver cirrhosis and cancer, and early treatment options were non-specific and could be toxic. Work aimed at elucidating the viral life cycle has led to better treatment options through the development of direct-acting antivirals, as exemplified by the work of Ralf Bartenschlager, Charles Rice, and Michael Sofia who have received the Lasker∼DeBakey C...
