Title: Pharmaceutical therapeutic use of glutathione derivatives
Inventor: OHLENSCHLAEGER GERHARD
IPC: A61P15/00
Filed: 1988-07-08
Abstract: Two glutathione thiol derivatives, namely the monomethyl ester and the monoethyl ester of reduced glutathione, are proposed for use as medicaments for a wide range of different indications, also in combination with vitamins, an amino acid or a substance which contains a semiconductor element in inorganically or organically bound form. The proposal is based on the knowledge that many disorders of cell metabolism can be rectified by glutathione therapy and therefore many disorders which are accompanied or caused by the loss of the reductive potential can be cured.

Abstract: The invention relates to a method and apparatus for cleaning gas mixtures, in particular flue gases from refuse incinerators, by removing heavy hydrocarbons and derivatives thereof, above all organic toxic and carcinogenic compounds from the group of the dioxines, after optional cooling and/or after pre-precipitation of solid disperse particles, and the usual pollutants such as, for example, sulphur dioxide, sulphur trioxide, nitrogen oxides, hydrogen chlorides and other simple compounds of halogen elements. The method according to the invention is characterised in that a dispersion of natural and/or synthetic hydrocarbons, especially mineral oils, oligomers, plastics and elastomers, is contacted with one or more elements in combination, in contact with a stream of the gas mixtures subjected to the cleaning, by spraying or flowing down on supports or by fluidising, whereby the precipitation of the organic toxic and carcinogenic compounds from the gas mixtures is achieved due to their affinity to the elements of the said hydrocarbon dispersions. <IMAGE>

Abstract: Consolidated earth surface, in particular a traffic surface, sports surface or the like, which possesses a top layer (18) designed as a drainage layer and a supporting layer (17), which contains so many cavities that they can absorb the volume of water produced by a disastrous rainfall, which is then channelled past a frost-protection layer (12) into the subsoil (11) where it seeps away or is passed into the drainage system via drainage pipes (25), after a time lag. The effect is to prevent the water acting as receiving water courses from being excessively polluted by a surge of contamination in the case of sudden downpours. <IMAGE>

Le guide d'énergie est associé de façon opérationnelle à la source d'énergie, de sorte que l'énergie d'éclairage provenant de la source d'énergie est reçue par le récepteur d'énergie, puis couplée dans le noyau et guidée vers la sortie d'énergie pour émerger du noyau au niveau de la sortie d'énergie. Un premier organe de focalisation (39) est associé de façon opérationnelle à la sortie d'énergie, de façon à focaliser au moins une partie d'énergie d'éclairage émergeant du noyau à l'intérieur d'un volume à réseau de points limité par diffraction et comportant une partie centrale qui, lors de l'utilisation, coupe un objet (40) avec lequel elle forme une intersection. Un second organe de focalisation (39) est associé de façon opérationnelle au premier organe de focalisation, de façon à recueillir l'énergie sortante provenant du volume et résultant de l'interaction entre l'énergie d'éclairage contenue dans le volume et l'objet et/ou résultant de la transmission ou de la réflexion de l'énergie d'éclairage depuis le volume. Le microscope comprend un détecteur (45) comportant une ouverture et un élément de détection, le détecteur étant associé de façon opérationnelle au second organe de focalisation, lequel forme une image de l'ouverture sur la partie centrale. L'ouverture numérique, NA, de l'énergie sortante provenant de la partie centrale et focalisée sur l'ouverture, la longueur d'onde de l'énergie sortante, lambda, et le diamètre moyen, d, de l'ouverture sont liés par l'équation: NA 0,6 x lambda/d, grâce à laquelle le détecteur peut détecter l'énergie sortante.
