13. Efeitos do cloreto mercúrico sobre o tecido ósseo de ratos
The mercury is used in the industry, medicine, agriculture and other fields. However, little is known about its involvement with the bone metabolism. The aim of this study was to evaluate the physical, biochemical and biomechanical bone parameters in adult rats contaminated with mercuric chloride during the development phase. The animals were separated as co

14. EFFECT OF DIPHENYL DISELENIDE ON TOXICITY INDUCED BY MERCURIC CHLORIDE IN MICE / EFEITO DO DISSELENETO DE DIFENILA SOBRE A TOXICIDADE INDUZIDA POR CLORETO DE MERCÚRIO EM CAMUNDONGOS
Mercury is a metal without physiological functions in human body and is toxic to human beings. This metal has many applications in industry and, therefore it is very important in occupational and environmental exposure. The toxicity of mercury depends on the form of the metal and can affect several organs, such as brain, kidney and liver. In addition, mercur

15. Efeito dos carotenóides licopeno e astaxantina sobre danos renais induzidos por cloreto de mercúrio. / Effect of lycopene and astaxanthin carotenoids on renal damage induced by mercuric chloride.
O mercúrio é um metal pesado com toxicidade comprovada, capaz de causar danos em qualquer tecido com o qual tenha contato, sendo o rim o principal alvo para sua forma inorgânica. O estresse oxidativo tem sido apontado como um importante mecanismo molecular para a injúria renal induzida por mercúrio inorgânico e a interação desse metal com moléculas

16. Peripheral markers of oxidative stress in chronic mercuric chloride intoxication
The present study was designed to evaluate the time course changes in peripheral markers of oxidative stress in a chronic HgCl2 intoxication model. Twenty male adult Wistar rats were treated subcutaneously daily for 30 days and divided into two groups of 10 animals each: Hg, which received HgCl2 (0.16 mg kg-1 day-1), and control, receiving the same volume of

17. 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

18. Effect of Transpiration-reducing Chemicals on Growth, Flowering, and Stomatal Opening of Tomato Plants 1
Phenyl mercuric acetate, 8-hydroxyquinoline, N-dimethylamino succinamic acid, or 2-chloroethyl trimethyl ammonium chloride were sprayed on 37-day-old tomato (Lycopersicon esculentum Mill. cv. Sioux) plants seven times at weekly intervals. Plants of nearly normal appearance resulted with all treatments except 2-chloroethyl trimethyl ammonium chloride. There w

19. GROWTH OF STAPHYLOCOCCI ON MERCURIC CHLORIDE AGAR
Smith, P. B. (Communicable Disease Center, Atlanta, Ga.). Growth of staphylococci on mercuric chloride agar. J. Bacteriol. 84:1016–1019. 1962.—An attempt has been made to corroborate a report that “epidemic” strains of staphylococci are more resistant to mercuric salts than are “nonepidemic” strains. A comparison of mercury resistance with coagul

20. Evaluation of intestinal parasite morphology in polyvinyl alcohol preservative: comparison of copper sulfate and mercuric chloride bases for use in Schaudinn fixative.
As a result of disposal problems inherent in the use of mercury compounds, many laboratories have considered using copper sulfate as a substitute for mercuric chloride in polyvinyl alcohol (PVA) preservative. The primary use for PVA-preserved specimens is the permanent stained smear, the most important technique for the identification of intestinal protozoa.

21. Comparative Efficacy of Pre-feeding, Post-feeding and Combined Pre- and Post-feeding of Two Microdoses of a Potentized Homeopathic Drug, Mercurius Solubilis, in Ameliorating Genotoxic Effects Produced by Mercuric Chloride in Mice
Mercury and its derivatives have become an alarming environmental problem, necessitating the search for effective antagonists, including homeopathic drugs, which are generally used in micro doses and are devoid of any palpable side-effects. On the basis of homeopathic similia principle, two potencies of Mercurius solubilis (Merc Sol-30 and Merc Sol-200) were

22. Urinary mercury excretion and proteinuria in pathology laboratory staff.
The use of mercuric chloride as an histological fixative was associated with high environmental atmospheric concentrations of mercury vapour (up to 0-5 nmol/l) as well as mercury compounds (total Hg to 1-0 nmol/l). Technicians exposed to this environment showed increased urinary mercury (median value 265 nmol/24h) and protein outputs (median value 117 mg pro

23. Plasmid conferring increased sensitivity to mercuric chloride and cobalt chloride found in some laboratory strains of Escherichia coli K-12.
Some lines of the widely used strain CR34 of Escherichia coli K-12 carry a plasmid. The plasmid has a mass of 12 +/- 2 X 10(6) megadaltons and is maintained at a low copy number per cell (1 to 2), and this number is not amplified by growth of cells in the presence of chloramphenicol. The plasmid is designated as pCU3. The presence of pCU3 confers on the stra

24. Comparison of methods to measure acute metal and organometal toxicity to natural aquatic microbial communities.
Microbial communities in water from Baltimore Harbor and from the mainstem of Chesapeake Bay were examined for sensitivity to mercuric chloride, monomethyl mercury, stannic chloride, and tributyltin chloride. Acute toxicity was determined by measuring the effects of [3H]thymidine incorporation, [14C]glutamate incorporation and respiration, and viability as c
