Information is meager concering the influence of salts on the metabolic processe of halophiles. In fact, reports of the work of Robinson et al. (1952) are the only recent studies in this field. Robinson (1952) showed that there was an optimum concentration of sodium chloride for maximum activity of lactic acid dehydrogenase. While studying the effect of salt on Micrococcwu halodenifns, Robinson...

Entry of formate, acetate, succinate, and salts of several other organic acids into barley roots takes place chiefly as ions from solutions at pH 5 to 7. The results are in accord with entry of the organic acid predominantly at pH 5 as ions through hydrophylic regions of the limiting membranes rather than by distribution of the undissociated acid to lipid-rich regions, as has previously been he...

In this paper we used a previously reported model for examining the adsorption of nonelectrolytes in solution by solid adsorbents to study the adsorption of lithium(I) cations by acid and sodium amberlites, which is an ion-exchange process. Based on the results, both are equilibrium processes and obey a kinetic law with a unity partial order in the Li+ concentration. The kinetic results were us...

With the method of in vitro incubation of the isolated rabbit cornea with the modified KEI medium, the effects of ouabain applied to the endothelial surface have been investigated. The change in corneal hydration with varying concentrations of ouabain was determined; one-half maximum rate of corneal swelling was found at an ouabain concentration of 3 x 10~ moles per liter. Endothelial permeabil...

The experiments to be described deal with the penetration of C4-labeled erythritol, mannitol, and sucrose in resting and stimulated axons of the squid Doryteuthis plei. The results indicate an increase in the penetration of the nonelectrolytes in the stimulated axons. This increase may be due either (a) to a change in the structure of the axolemma or (b) to a drag effect of the sodium ions ente...

An attempt was made to establish a concentration--time relationship for continuous and interrupted inhalation of a number of nonelectrolytes to establish norms for the permissible content of harmful substances in atmospheric air. The tests showed that the indicated relationship can be expressed in the form of a straight line on a logarithmic grid by using either acute toxicity parameters or the...
