Acute Exposure If recovery from nerve agent poisoning occurs, it will be complete unless anoxia or convulsions have gone unchecked so long that irreversible central nervous system changes due to anoxemia have occurred.

The clinical manifestations of hyponatremia are nonspecific weakness and apathy occur in mild cases, and central nervous system changes (lethargy, coma, and seizures) are present in more severe cases. No signs or symptoms are specific for SIADH. History, physical examination, and routine laboratory test results often suggest that hyponatremia is dilutional or depietional.

The toxic threshold limit value as reported by Sax (Ref 3) ia ( pm in air or 750mg/m of air, and by Plunkett (Ref 8) is lOOppm and 375mg/m. Acute poisoning from the use of toluene is the result of a small amount of benz in commercial (coal-tar) derived toluene. Table 1 presents the effects of toluene vapor (Ref 4). Plunkett (Ref 8) reports that prolonged exposure to toluene vapor can result in permanent central nervous system changes such as cerebellar degeneration, tremulousness, ataxia, emotional lability and EEC changes... 

Central nervous system changes are the most frequently observed systemic toxicities of lidocaine. The initial manifestations are restlessness, vertigo, tinnitus, slurred speech, and eventually, seizures. Subsequent manifestations include CNS depression with a cessation of convulsions and the onset of unconsciousness and respiratory depression or cardiac arrest. This biphasic effect occurs because local anesthetics initially block the inhibitory GABAergic pathways, resulting in stimulation, and eventually block both inhibitory and excitatory pathways... 

In addition, the manifestations of dietary copper deficiency occur in animals that consume diets that contain copper antagonists, such as sulfide ion, molybdenum, zinc, silver, mercury, and cadmium (Evans, 1973). The extent and type of disorders associated with copper deficiency depend on species, age, sex, and severity of deficiency, but the disorders generally include anemia achromotri-chia lesions of the cardiovascular system, lung, skeleton, and central nervous system changes in the growth and appearance of hair, fur, or wool impaired growth and reproductive failure.
