Untersuchungen über die Durchgängigkeit der Membran des runden Fensters für Tetracycline
Studies on the permeability of the bound window membrane for tetracycline
The permeability of the round window membrane of the guinea pig was tested with different substances e.g. rhodamine, gamma-globuline and especially tetracycline. Through the application of dimethyl-tetracycline which is highly fluorescent and the simultaneous application of tetracain, different organic and hypertonic aqueous solutions tests were made to show if any changes occur in the ability to penetrate.
