DNA lesions in nuclei isolated from rat tissues following i.p. injection of the carcinogen nickel carbonate were measured by the alkaline elution technique. Kidney, liver, lung, and thymus gland nuclei were examined at 3 and 20 hr after treatment for the presence of DNA single-strand breaks and cross-links. Single-strand breaks were detectable in lung and kidney nuclei, and both DNA-protein and...

N ickel contam ination of intravenous fluids warrants concern, owing to three specific toxic effects o f Ni2+: (a) cardiac toxic ity , especially increased coronary artery resistance, (b ) oxytocic action on th e u terus, and (c) allergic reactions, since nickel is a common allergen. In ad­ dition, high concentrations of nickel in in trav en o u s flu ids cou ld evoke n o n ­ specific toxic res...

A comparison was made of the bronchoalveolar lavage fluid (BALF) response to ultrafine nickel (Uf-Ni) and standard-sized nickel (Std-Ni). Rats were intratracheally instilled with 0, 0.1, 0.5, 1 and 5 mg Uf-Ni and Std-Ni, respectively. At 3 d after instillation, the body weight and wet lung weight were determined. At the same time, BALF was analyzed for lactate dehydrogenase (LDH), total protein...

Nickel compounds are widely used in industries and have been massively introduced in the environment in different chemical forms. Here we report the effect of two different chemical forms of nickel, NiCl2 and nickel nanoparticles (NiNPs), on the reproduction of the marine calanoid copepod Acartia tonsa. The behavior of nickel nanoparticles was analyzed with different techniques and with two pro...

Art materials are used by individuals of all ages, ranging from kindergarten children to adults studying the arts at a university level, as well as the general public, senior citizens, and mentally compromised individuals. Art materials have the potential of containing toxic materials, including carcinogens (such as nickel, chromium, cadmium, and lead) and reproductive toxins in their formulati...

OBJECTIVE The aim of the study was to compare and evaluate the in vitro biodegradation of nickel and chromium from space maintainers, made of three different companies, i.e (Dantaurum, Rocky mountain and Dtech) in artificial saliva. MATERIALS AND METHODS The study comprised of 30 space maintainers out of which 10 were fabricated using Dantaurum, 10 using Rocky mountain and 10 using Dtech band...

BACKGROUND Lack of knowledge regarding particulate matter (PM) characteristics associated with toxicity is a crucial research gap. Short-term effects of PM can vary by location, possibly reflecting regional differences in mixtures. A report by Lippmann et al. [Lippmann et al., Environ Health Perspect 114:1662-1669 (2006)] analyzed mortality effect estimates from the National Morbidity, Mortalit...

Nickel damages the male reproductive system. We investigated beneficial effects of silibinin which has metal-chelating and antioxidant properties over nickel toxicity. Both antioxidative in testes overall related to sperm motility, membrane acrosome integrity orally administered Silibinin were evaluated against harmful 30 day intraperitoneal sulfate (5 mg/kg/day) administration rats. Male rats ...
