Dietary supplementation of Pleurotus tuber regium in rat feed ameliorates metabolic and hematotoxicity induced by carbon tetrachloride.

Pleurotus tuber regium, a wild edible mushroom can reduce free radical-mediated injury and oxidative stress induced by carbon tetrachloride (CCl4) via improvement of antioxidant capacity. This work evaluates the protective effects of this mushroom against the metabolic and hematological toxicity induced by CCl4. Sixty male Sprague Dawley rats were divided into six groups (n = 10).

Potential hazards of toxic metals found in toothpastes commonly used in Nigeria.

Background: Toothpastes have multi-functional configurations as oral care products. They can however constitute a pos- sible source, amongst others, of toxic metal exposure in public health. Indeed, the public health impact of personal hygiene and consumer products is largely unknown.

Human health hazards of poly aromatic hydrocarbons in Nigerian smokeless tobacco.

Recently we investigated the heavy metal hazards of Nigerian smokeless tobacco products 'STP'. Since 'STPs' are advocated as safer alternatives to cigarets, the public health implication should be ascertained. This is a risk assessment of poly aromatic hydrocarbons 'PAHs' in 'STPs' used in Nigeria.

Heavy metal hazards of Nigerian smokeless tobacco.

Background: Interest is rising in smokeless tobacco as a safer alternative to smoking. Information on the heavy metal hazards of smokeless tobacco is sparse in Nigeria, as it is in most sub-Saharan Africa countries. This study assesses the heavy metal hazards of the smokeless tobacco types commonly available in Nigeria.
