Witryna1 Miosis was present in all cases seen due to Novichok agents – however, experience with other nerve agents mydriasis may be present where nicotinic effects predominates, and therefore the best clinical summary is that painful blurred vision is the best descriptor of potential clinical presentations with either miosis or mydriasis being present. History Early pioneers in the field include Jean Louis Lassaigne (early 19th century) and Philippe de Clermont (1854). In 1932, German chemist Willy Lange and his graduate student, Gerde von Krueger, first described the cholinergic nervous system effects of organophosphates, noting a choking sensation and … Zobacz więcej In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure O=P(OR)3, a central phosphate molecule with Zobacz więcej The phosphate esters bearing OH groups are acidic and partially deprotonated in aqueous solution.

Witryna1 sty 2015 · Nerve agents also interact with detoxification enzymes such as carboxylesterases (CarbE) and A-esterases (e.g., arylesterase and paraoxonase), and the degree of such interaction can alter the magnitude and extent of the toxic cascade after AChE inhibition (Gupta et al., 1991, Pope, 1999, Pope and Liu, 2002, Fonnum … Nerve agents attack the nervous system. All such agents function the same way resulting in cholinergic crisis: they inhibit the enzyme acetylcholinesterase, which is responsible for the breakdown of acetylcholine (ACh) in the synapses between nerves that control whether muscle tissues are to relax or contract. If the agent cannot be broken down, muscles are prevented from receiving 'relax' signals and they are effectively paralyzed. It is the compounding of this paralysi…
