Arteriolar diameters and venular erythrocyte velocities in the small pial vessels on the surface of the cat brain were measured by TV methods during induced epileptic seizures through a cranial window. Grand mal seizures maximally dilated arterioles and increased venular erythrocyte velocity up to 400%. High positive correlation existed between changes in CSF hydrogen ion concentration and pial...

My answer to all these questions is: Use the concentration of titratable hydrogen ion in the extended extracellular fluid (at the actual oxygen saturation), ctHEcf, as the relevant measure of an overall metabolic acidosis or alkalosis, which may be due to several cooperative or counteractive pathophysiological processes. ctHEcf and SBE are numerically equal, with opposite sign, but it is the hy...

1. Ions with the opposite sign of charge as that of a protein ion diminish the swelling, osmotic pressure, and viscosity of the protein. Ions with the same sign of charge as the protein ion (with the exception of H and OH ions) seem to have no effect on these properties as long as the concentrations of electrolytes used are not too high. 2. The relative depressing effect of different ions on th...

background and aim: 2,4-dichlorophenol (dcp) is a compound  generated in a variety of industrial processes and also by chlorine disinfection of water polluted with phenolic compounds . dumping of dcp into the environment and water resources is of great concern because of the compound's intense odor and toxicity. dcp is very soluble and resistant to biodegradability so it cannot be removed ...
