Induced loss in cerebral tissues of respiratory response to electrical impulses, and its partial restoration by additional substrates

Abstract

readily pass through the walls of the glomeruli and account for the high excretion rate when silica is ingested or injected. Large polymers of silicic acid form adsorption complexes with polar and hydr- oxylic organic molecules which may be soluble in organic solvents such as ethanol and dioxan. Silicon also occurs in the tissues in a form which is not excreted and is not soluble in organic solvents. The nature of these complexes is under investigation. SUMMARY 1. The silicon in tissues has been studied by injecting into rats silicate solutions containing 3lSi. Muscular tissue retains the least "'Si, kidney tissue the most.
