The Enigma of Parkinsonism in Chronic Borderline Mercury Intoxication

A 47 year old female dentist suffered from hemiparkinsonism which had started eighteen months earlier and was manifested mainly by resting tremor and cogwheel rigidity. A baseline quantitative urinary mercury excretion was 46 micrograms/day. The patient was treated with chelating agent d-penicillamine for a week. Chelation therapy resulted in clinical improvement of parkinsonism and in dynamic changes in daily urinary mercury excretion with a prompt...

Mercury and Nickel Allergy: Risk Factors in Fatigue and Autoimmunity

This study examined the presence of hypersensitivity to dental and environmental metals in patients with clinical disorders complicated with chronic fatigue syndrome. Three groups of patients were examined through medical history, dental examination, and by using a modified test of blast transformation for metals-MELISA(R). The three groups consisted of the following: 22 patients with autoimmune thyroiditis with or without polyglandular autoimmune activation; 28 fatigued patients...

Effects of Metals on the Nervous System of Humans and Animals

Several metals have toxic actions on nerve cells and neurobehavorial functioning. These toxic actions can be expressed either as developmental effects or as an increased risk of neurodegenerative diseases in old age. The major metals causing neurobehavioral effects after developmental exposure are lead and methylmercury. Lead exposure in young children results in a permanent loss of IQ of approximately 5 to 7 IQ points, and...

Mercury chloride has shown some carcinogenic activity in male rats, but the evidence for female rats and male mice is equivocal. Other mercury compounds and metallic mercury have not been tested adequately in experimental animals. Epidemiologic data are...
