Roles The primary role of the Hyperbaric Medicine Unit is to provide treatment for any casualties that arise from military diving training at the Defence Diving School. Fortunately such casualties are infrequent but, since inexperience is associated with likelihood of a diving accident, the natural choice of location for a fixed facility is close to the diving training establishment. Another im...
Recent investigations have disclosed a decrease in pentose phosphate shunt activity in hereditary pyrimidine 5'-nucleotidase deficiency. Clinical lead poisoning is associated with an acquired decrease in pyrimidine 5'-nucleotidase activity. The current investigations were undertaken (1) to determine if pentose shunt activity was decreased in erythrocytes exposed to lead, and (2) to compare the ...
Background and purpose: Cyanide is a species of high toxicity that is found mostly in industrial effluents such as electroplating, metal mining, metallurgy and metal cleaning processes. Entrance of it to existing environment contains a hazardous to health. The purpose of this study was to compare efficiency of both sonochemical and sonochemical / hydrogen peroxide processes for cyanide rem...
A major need exists for methods to assess organ oxidative metabolic states in vivo. By contrasting the responses to cyanide (CN) poisoning versus hemorrhage in animal models, we demonstrate that diffuse optical spectroscopy (DOS) can detect cytochrome c oxidase (CcO) redox states. Intermittent decreases in inspired O2 from 100% to 21% were applied before, during, and after CN poisoning, hemorrh...
Sulfur containing impurities are known to cause severe and irreversible poisoning of Pd membranes during the hydrogen separation application (Especially in the coal gasification) resulting in the reduction of hydrogen permeability, selectivity and structure deterioration of Pd membranes. Pd/Au alloys are found to show high sulfur resistance in comparison to pure Pd and other Pd based alloys (i....
It is well known that the cyanides and the nitriles when given to mammals leave the body in part as sulfocyanides. This suggests that they combine with the labile sulfur group of the albumins of the cell, and it was this fact which led us to undertake a study of the spontaneous oxidation of cystein. It is not necessary to recapitulate the evidence that the cyanides act on cell-respiration, sinc...
