To investigate if part of the progressive reduction of intraocular pressure (IOP), seen when physostigmine is applied on alternate hours, is due to a reduced aqueous flow. In a randomized, open study, one drop of physostigmine salicylate, 8 mg/ml, was

We evaluated a double-blind, placebo-controlled, and double-crossover trial of oral physostigmine salicylate for a 9-month period in 13 of 25 patients with sporadic amyotrophic lateral sclerosis (ALS). A large dropout rate of 48% was secondary to eight deaths and four

Organophosphorus-induced delayed polyneuropathy (OPIDP) is thought to result from organophosphorylation of neuropathy target esterase (NTE; formerly known as neurotoxic esterase), followed by an "aging" of the phosphorylated NTE. Protection against OPIDP should thus be achieved by production of an inhibited

In an investigation of 2 closely related Miniature Horses with a history of excessive sleepiness, depression and episodes of collapse, a diagnosis of narcolepsy was made on the basis of neurological examination and pharmacological testing. Further investigations included electroencephalographic examination
