1. Mercury Exposure in a Riverside Amazon Population, Brazil: A Study of the Ototoxicity of Methylmercury
Introduction Mercury poisoning causes hearing loss in humans and animals. Acute and long-term exposures produce irreversible peripheral and central auditory system damage, and mercury in its various forms of presentation in the environment is ototoxic.
Objective We investigated the otoacoustic emissions

2. EFEITO DE ANTIOXIDANTES SOBRE OS NÍVEIS DE METALOTIONEÍNAS EM CAMUNDONGOS TRATADOS COM CLORETO DE MERCÚRIO / EFFECT OF ANTIOXIDANTS ON METALLOTHIONEIN LEVELS IN MICE TREATED WITH MERCURIC CHLORIDE
In this study, acute effects of mercury on mouse blood, kidneys and liver were evaluated. Mice received a single dose of mercuric chloride (HgCl2 - 4.6 mg/kg, subcutaneously) for three consecutive days. We investigated the possible beneficial effects of antioxidant therapy (N-acetylcysteine (NAC) and diphenyl diselenide (PhSe)2) comparing to sodium salt of 2

3. The reconstruction of color spaces: type 2 diabetes and mercury vapour intoxication / Reconstrução do espaço de cores de pacientes com discromatopsia adquirida: diabéticos tipo 2 e intoxicados por vapor de mercúrio
Purpose. Color vision was examined in two groups of patients, one group with diabetes mellitus type 2 (DM2) without retinopathy (n=32) and a second group with chronic exposure to mercury vapour (Hg) (n=18), as well as in the respective age-matched controls (n=23; n=18) in order to reconstruct their color spaces. We assessed the type and degree of distortions

4. Avaliação neuropsicológica de pacientes expostos ao vapor de mercúrio e de pacientes diabéticos do tipo 2 / Neuropsychological assessments of patients exposed to mercury vapor and of type 2 diabetic patients
Neuropsychological function is known to be affected by exposure to toxic substances and metabolic disorders. Two descriptive studies were performed. The aim was to examine possible neuropsychological dysfunction in individuals with history of occupational exposure to mercury vapor, and in type 2 diabetic patients without retinopathy, in comparison with contr

5. O comportamento do metilmercúrio (metilHg) no ambiente
Methylmercury is the most hazardous mercury species known. Due to its high stability, lipid solubility, and ionic properties, this compound shows a high ability to cross membranes in living organisms, damaging the central nervous system, mainly the brain, and the effects of chronic poisoning are progressive. In this paper some aspects related to the toxicity

6. Mercurio y salud en la odontología
Mercury is a heavy metal widely used by man. It is considered very toxic causing conditions in the central nervous system, behavior disturbances, and renal and sexual disorders. For a century, mercury has been used in the dental practice for its capacity of joining metals (amalgamate), its low cost and its rapid fixing in dental pieces repair. Currently, the

7. Semiquantitative mercury determination in fish: a tool for poisoning prevention
A experiência da população japonesa relacionada à intoxicação por ingestão de peixe contaminado com mercúrio foi a base de muitos estudos. No Brasil, os peixes da região Amazônica, têm apresentado evidências de contaminação, colocando em risco a saúde da população ribeirinha. O monitoramento contínuo do teor de mercúrio nos peixes desta re

8. Cytogenetic damage related to low levels of methyl mercury contamination in the Brazilian Amazon
The mercury rejected in the water system, from mining operations and lixiviation of soils after deforestation, is considered to be the main contributors to the contamination of the ecosystem in the Amazon Basin. The objectives of the present study were to examine cytogenetic functions in peripheral lymphocytes within a population living on the banks of the T

9. Chronic inorganic mercury poisoning treated with N-acetyl-D-penicillamine
Gledhill, R. F., and Hopkins, A. P. (1972).Brit. J. industr. Med.,29, 225-228. Chronic inorganic mercury poisoning treated with N-acetyl-D-pencillamine. The case history is presented of a man intoxicated by mercury during his employment as a filler of thermometers. The mean daily urinary excretion of mercury was 661 μg for five estimations before treatment.

10. Mercury Poisoning from an Unsuspected Source
In the manufacture of zinc oxide the raw material normally used in zinc metal plates. In a factory in which old aeroplane batteries containing zinc mercury amalgam were substituted, it was not realized that mercury vapour was being produced. Of 25 workers exposed, seven developed serious chronic mercury poisoning and were admitted to hospital. The clinical f

11. Mercury Poisoning and Its Treatment with N-acetyl-D, L-Penicillamine
Two cases of chronic inorganic mercury poisoning of moderately rapid onset are described. Although exposure was the same in the two patients, the mercurial poisoning affected chiefly the kidneys in one and the gums in the other. Mercurialentis and corneal opacities were seen after short exposure to the metal.

12. Psychiatric aspects of methylmercury poisoning
Forty-three patients with methylmercury poisoning were studied; 74·4% showed some degree of depression. Their blood levels of mercury were higher than the average values for the whole group, and considerably higher than the blood levels of the non-depressed patients. Irritability was observed in 44·2% of the patients, all except one of the 19 being under 3
