Fenitrothion (Sumithion), and organophosphorous insectide, was applied dermally to rats. Cholinesterase activity was measured in blood and brain. The concentration of the pesticide in blood plasma and acetylcholine in brain were estimated at different intervals. The maximum concentration of Fenitrothion in the plasma was found at 4 hrs while significantly elevated levels of acetylcholine were p...
Chlorpyrifos is a broad spectrum moderately toxic organophosphorous insecticide. It is widely used in agriculture for pest control and in households as a termicide. However, exposure to chlorpyrifos and its metabolites can affect the public health resulting from its long residual periods in soil and water. Thus, there is an essential need to develop sensitive method for the detection of chlorpy...
Cancer progression has been associated with an increase in genomic instability indicated by inactivation of tumor suppressor genes and activation of oncogenes. Epidemiological and experimental evidence has implicated estrogens in the etiology of breast cancer. To study environmental organophosphorous pesticides is of interest since evidence indicate that pesticides may enhance cell division, in...
