Nerve agents belong to the most toxic organophosphates (OP) in the group of cholinesterase inhibitors. They can be used as chemical warfare agents and, they can be (and were) misused by terrorists, as happened in Matsumoto city (1994) and Tokyo subway (1995). Sarin was used in these cases. Medical protection against their effect (i.e. antidotal treatment) is of prime importance (Bajgar 2004, 20...

The present study evaluated the dose-response effects of subacute exposure to sublethal doses of the organophosphorus (OP) chemical warfare nerve agent (CWNA) sarin (GB) on the operant behavior of guinea pigs. Dietary restricted guinea pigs, trained to respond for food under a progressive ratio (PR) schedule of reinforcement, were injected five times per week (Monday-Friday) for 2 weeks with fr...

A number of recent terrorist attacks make it clear that rapid response, high sensitivity and stability are essential in the development chemical sensors for detection warfare agents. Nerve agent sarin [2-(fluoro-methyl-phosphoryl) oxypropane] is an organophosphate (OP) compound recognized as one most toxic Considering sarin’s toxicity, being odorless colorless, dimethyl methylphosphonate (DMMP)...

Seizurogenic chemicals include a variety of toxic agents, including chemical warfare agents, toxic industrial chemicals, and natural toxins. Chemical weapons such as sarin and VX, and pesticides such as parathion and carbaryl cause hyperstimulation of cholinergic receptors and an increase in excitatory neurotransmission. Glutamatergic hyperstimulation can occur after exposure to excitatory amin...
