organophosphorous compounds have been employed as pesticides and chemical warfare nerve agents. toxicity of organophosphorous compounds is a result of excessive cholinergic stimulation through inhibition of acetyl cholinesterase. clinical manifestations include cholinergic syndromes, central nervous system and cardiovascular disorders. organophosphorous pesticide poisonings are common in develo...
We examined human adipose tissue, liver, and bile from humans in Japan to understand the contamination status, specific accumulation, and elimination of two newly identified environmental contaminants, tris(4-chlorophenyl)methane (TCPMe), tris(4-chlorophenyl)methanol (TCPMOH), and other persistent organochlorines such as polychlorinated biphenyls (PCBs), DDT and its metabolites (DDTs), hexachlo...
GOAL, SCOPE AND BACKGROUND The anthropogenic environmental emissions of chloroacetic acids and volatile organochlorines have been under scrutiny in recent years because the two compound groups are suspected to contribute to forest dieback and stratospheric ozone destruction, respectively. The two organochlorine groups are linked because the atmospheric photochemical oxidation of some volatile o...
A colorimetric array for the chromogenic discrimination of organophosphorous derivatives in gas phase has been developed.
A case of organophosphorous poisoning in a 29 year old male who developed intermediate syndrome manifested by features of respiratory depression as evidenced by marked weakness of the respiratory muscles, tachypnoea, and drop in oxygen saturation despite reversal of nicotinic and muscarinic effects of organophosphorous poisoning. The case highlights its early recognition and prompt institution ...
Organophosphorous pesticides and nerve agents inhibit the enzyme acetylcholinesterase at neuronal synapses and in neuromuscular junctions. The resulting accumulation of acetylcholine overwhelms regulatory mechanisms, potentially leading to seizures and death from respiratory collapse. While current therapies are only capable of reducing mortality, elevation of the serum levels of the related en...
