Inventor: WANG CHONG GANG
IPC: A61K31/15
Filed: 2001-02-01
Abstract: Differences of physiology functions of the human muscle tissues are mainly determined by their own initiation and signal transmission systems, defined as pre-muscle molecular motor mechanism. However, at molecule level, mechanism of the muscle molecular motor is the same in all kinds of muscle tissues. The current medications, drugs, and therapies for diseases and symptoms related to abnormal muscle contraction are aimed just at the pre-muscle molecular motor mechanism, whereas without intending to effect on the muscle molecular motor mechanism at all.  The muscle molecular motor mechanism mainly involves recycling of actin-myosin filament cross-bridge and sliding movement. In the process, bio-energy provided by ATP hydrolysis is necessarily required. Therefore, abnormal muscle contraction under diseased conditions may be modified by inhibition of the muscle molecular motor with the actin-myosin ATPase inhibitor, which blocks hydrolysis of ATP, then reduces release of bio-energy for the muscle contraction, so called as bio-energy muscle relaxants.

Abstract: L'invention concerne un système et un procédé d'utilisation d'un laser (18) pour souder un substrat (12) en plastique à un matériau (14) adjacent tel qu'un carré de moquette synthétique. On met les matériaux en contact en tournant les surfaces principales dans des directions opposées, de manière à créer une interface entre les carrés. Le matériau le plus proche du laser (18) est transparent à la longueur d'onde du faisceau laser, ce qui permet de focaliser le faisceau laser incident dans une zone focale sur l'interface. L'autre matériau adjacent à l'interface absorbe la longueur d'onde, ce qui permet de chauffer ce matériau par le faisceau laser et, partant, de créer un motif de plusieurs zones de fusion, chaque zone de fusion étant constituée de plusieurs parties de chaque matériau. On refroidit ensuite ces zones de fusion, ce qui a pour effet de souder les uns aux autres les matériaux adjacents. On combine des additifs aux matériaux pour modifier leurs caractéristiques de transmission et d'absorption par rapport à la lumière visible et aux longueurs d'onde du laser.
