Abstract: Methods of treating a human patient suffering from Eustachian tube malfunctions are provided. A nasal spray or pharmaceutical composition containing a therapeutically effective amount of betahistine is administered to the patient. The nasal spray or pharmaceutical composition has particular applicability to alleviate the symptoms of Meniere's disease in persons suffering from abnormal Eustachian tube function, but also has an applicability to beneficially improve vascular oxygenation of the inner ear.

Abstract: A method of examining a bodily function. A first set of frequency characteristics and amplitude characteristics of a first electrical signal deriving from rhythmic activity of a nerve in a living body is detected at a first condition. The nerve is stimulated to a second condition and a second set of frequency characteristics and amplitude characteristics of a second electrical signal deriving from the rhythmic activity of said nerve is detected. The fundamental frequency present in the frequency characteristics is identified. From the fundamental frequency the frequencies corresponding to a plurality of octaves of said fundamental frequency are calculated. The amplitude of said electrical signals at said octaves is identified. For said first signal a first amplitude ratio is calculated being the ratio of the amplitude difference between a first pair of said octaves, and the amplitude difference between a second pair of said octaves.

Abstract: The invention concerns an arrangement for the bending of laying tubes for wire-winding layering apparatuses, in which the molding body that determines the form of the laying tube runs essentially horizontally and is rotatably supported, such that a better manipulation of the highly heated laying tube is achieved during bending. The molding body also consists of two drums, one inserted into the other, the outer one of which has a lateral edge that matches the laying tube form desired and the two drums have a generated surface that matches the laying tube form desired. Together, they serve as the stop surfaces for the bending process. In this manner, the bending of the laying tubes is considerably simplified and a precise laying tube form is achieved.
