  • Patent number: 9107889
    Abstract: The present invention relates to solid compositions comprising a substance which improves nitric oxide (NO) availability, re. an NO donor or a precursor of the biosynthesis of nitric oxide or an direct or indirect NO agonist, with arginine being a preferred compound, in combination with a dithiolane, with ?-lipoic acid as a preferred compound, and its use for improvement of sexual function. The compositions according to the invention comprise the NO donor or its precursor in excess, based on the molar amount of the constituents. The compositions are also suited for the improvement of sexual function. In particular the present invention relates to the use of a dithiolane in combination with a NO donor or a precursor thereof for the preparation of a medication for treatment of sexual dysfunction.

  • Patent number: 5528619
    Abstract: In order to produce a gas discharge structure for two-dimensionally extending gas discharges comprising a pair of electrodes including a first and a second electrode which have mutually facing electrode surfaces, a gas discharge space arranged between the electrode surfaces with a plasma gas provided therein and a high frequency source with which a current can be fed into the pair of electrodes for producing a plasma between the first and the second electrode, in such a way that wavelength dependent modulations of the field strength substantially no longer occur in the gas discharge space, it be proposed that, the electrode surface of the first electrode is divided into two partial electrode surfaces that are located adjacent to one another in this electrode surface but are electrically separated from one another, that the partial electrode surfaces have mutually facing edge regions which extend at a defined distance from one another, that the partial electrode surfaces be connected to two terminals of the hi
