Abstract: Novel glycosides, especially steroidal and non-steroidal glycosides are provided. The steroidal and non-steroidal glycosides preferably are prepared from aglycons which possess valuable properties such as pharmacological properties. The glycosides are prepared from useful aglycons and possess useful properties which are the same as those of their respective unglycosylated aglycons. The glycosides are provided in acylated and deacylated form. The acylated glycosides after hydrolysis of the acyl groups possess enhanced water solubility properties, as illustrated in the case where the aglycon is acetominophen.

Abstract: A method for in vivo treatment of tumorous tissues on body surfaces that comprises the step of irradiating said tissues by polarized light of predetermined intensity, this polarized light predominantly includes wavelength components exceeding 300 nm and substantially excludes ultraviolet components.A new use of a light source emitting polarized light includes the application of said light source for irradiating tumorous tissues on body surfaces.

Abstract: A mehtod for mixing water and diesel fuel in a ratio between 5 and 20 Vol %, in which the liquid components are recirculated in a recirculation loop comprising an ellipsoidal vortex chamber (10) in which rotation around a longitudinal axis (9) is attained, the rotating fluid is expanded and tangentially injected in a baloon-like second vortex chamber (16) with an axis (17) normal to that of the first chamber, the open lower end of the second rotational chamber (16) is connected to fluid inlets and suction side of a recirculating pump. The outlet occurs from the equatorial plane of the second vortex chamber. The outflow rate should be at least ten times less than the flow in the recirculation loop. The mixture which have water droplets smaller than 200 nm has a consistency similar to that of fuel and can be used as fuel to diesel engines, whereby the amount of unwanted components in the exhaust gases will be reduced.
