  • Patent number: 6139876
    Abstract: A gelatin with increased oxygen content for pharmaceutical, cosmetic and/or veterinary use. The gelatin comprises a gelling agent and a solvent, furthermore oxygen in a substantially even distribution with a pressure exceeding normal atmospheric pressure, wherein the surface tension of the gelatin is sufficiently high to retain at least a portion of the overpressure of the oxygen throughout a predetermined period of time after having been exposed ton atmospheric environment. Glucose and bactericide and/or fungicide agents can be added to facilitate cellular metabolism and decrease the danger of local infections. The solvent can be distilled water or a physiologic saline solution.

  • Patent number: 5219879
    Abstract: The present invention relates to novel substituted 15-oxa-, 15-thia-, and 15-aza- dihydrolanosterols, to pharmaceutical compositions containing such compounds, and to methods of using these compounds to suppress the activity of 3-hydroxy-3- methylglutaryl coenzyme A reductase (HMGR), an enzyme which is important in cholesterol biosynthesis. The overall effect of these heterocyclic lanosterol analogs is to decrease cholesterol formation, thereby resulting in lower serum cholesterol levels in mammals, and impaired ergosterol synthesis in fungi.
