    Effects of L-ascorbic acid supplementation on dieldrin toxicity in rats (1982)
    Springer
    Archives of toxicology 50 (1982), S. 227-232

    Notes: Abstract Chronic dieldrin administration to rats (5 mg/kg/day) produced pathological changes in liver and kidney tissues. Dieldrin treated rats showed high levels of liver ascorbic acid and increased activities of inorganic pyrophosphatase in brain and glucose-6-phosphatase in liver. The activities of Mg2+-ATPase in liver and acetylcholinesterase in brain were decreased under toxic doses of dieldrin. L-Ascorbic acid supplements in treated animals could partially prevent the pathological alterations, as observed histologically in liver and kidney tissues. Administration of this vitamin could also prevent alterations in some enzyme activities produced by toxic dieldrin doses.

    A suitable extractant for assessing plant-available copper in different soils (peaty, red and alluvial) (1982)
    Springer
    Plant and soil 68 (1982), S. 131-134 
    Details
    ISSN: 1573-5036
    Keywords: Alluvial soil ; Available copper ; Copper uptake ; Extractant ; Peaty soil ; Red soil

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Relative efficiency of five chemical extractants for the extraction of available Cu in four different soils and its uptake by rice seedlings was studied in a pot culture experiment. The Cu extracted by 0.1N HCl showed significant relationship with plant uptake whereas the values for other extractants except 0.05M EDTA did not approach the level of significance. Among the soil properties studied, pH and CaCO3 correlated negatively and organic matter and CEC positively with Cu uptake by rice plants.
