Potentially toxic metals in dust, blood, and hairs from exposed security dogs in an oil and gas industry.

Environmental pollutants pose a health risk to animals and humans. We evaluated levels of some potentially toxic metals in environmental dust, blood, and hair samples of apparently healthy security dogs from a crude oil well drilling site (A) and liquefied natural gas production site (B) industrial environments in Nigeria. These samples were routinely digested and analyzed for lead, cadmium, nickel, chromium, and zinc using atomic absorption spectrophotometry assay.

Ameliorative properties of aqueous extract of Ficus thonningii on erythrocyte osmotic fragility induced by acetaminophen in Rattus norvegicus.

In vitro antioxidant and erythrocyte protecting activities by aqueous extract of Ficus thonningii leaves on blood cells were studied in acetaminophen treated rats. The extract was safe at limit dose of 5000 mg kg(-1) body weight. The extract demonstrated dose dependent antihemolytic effect at dose levels between 50 and 200 mg kg(-1) body weight.
