Biionic potentials in the proximal tubule of Necturus kidney.

1. Biionic potentials were studied in the proximal tubule of the doubly perfused Necturus kidney and subsequently analysed by means of an equivalent electrical circuit.2. Luminal membrane resistance was found to be at least 3 times greater than peritubular membrane resistance.3. Potassium contribution to peritubular membrane conductance amounts to at least 75%. Replacement of chloride in peritubular circulation by benzene sulphonate or acetyl glycinate hyperpolarized peritubular membrane.4. The peritubular membrane is more permeable to choline than to sodium. Indirect evidence suggests that the opposite may apply at the luminal border.5. The shunt pathway discriminates poorly, if at all, between sodium, potassium and choline, in short term experiments.6. Chloride permeability across the shunt pathway is about three times as great as combined cationic permeabilities.

[Elastomeric impression materials].

A review of the literature on elastomeric impression materials, is presented in this paper. The article mentions the composition and the most important properties of the elastomeric impression materials used in dental practice. The clinical significance of these materials, physical and mechanical properties are also emphasized. In addition some new elastomeric impression materials with improved properties and a new (experimental) light-cured impression material, are mentioned. Another part of this article is the biocompatibility of these materials. In the end the great significance of handling is outlined.
