  • Patent number: 5260284
    Abstract: The present invention discloses unique methods employing mixtures of phospholipids and neutral lipids for surfactant replacement therapy in the treatment of the various forms of respiratory distress syndrome. These compositions are shown to greatly enhance the surfactant replacement efficiency of surface-active lipids. In this regard, experimental models have shown that both the surface-tension lowering effect and rate of phospholipid absorption to an air/liquid interface are accelerated by the addition of triglycerides and/or sterols to mixtures of saturated or unsaturated phospholipids. Such compositions are therefore theorized to give new and enhanced therapeutic value to the use of surface-active lipids for surfactant replacement therapy in a subject without risk of immunogenic response. The subject methods also comprise a simple, rapid and inexpensive means for the deposition of polar lipids to a variety of air/liquid interfaces.

  • Patent number: 5250442
    Abstract: A method of treating rheumatoid arthritis which includes first, taking a blood test to determine a rate of erythrocyte sedimentation and a rheumatoid factor, and then fasting for a 12-hour period prior to orally administering a 500 milligram dosage of tetracycline achromycin, and observing any change in the symptoms of the rheumatoid arthritis including reduction of swelling and pain in the affected sites. This process is repeated over 24-hour cycles until the rheumatoid factor has decreased by at least 50% from the first determined level prior to treatment and erythrocyte sedimentation decreased, at which point the 24-hour cycles are continued, reducing the dosage of tetracycline achromycin to 250 milligrams until the symptoms of the rheumatoid arthritis condition disappear.

  • Patent number: 5200400
    Abstract: Method for inhibiting acute rejection of a transplanted organ or tissue by a recipient mammal that includes the steps of administering to the mammal a compound which causes selective sensitization of the alloreactive lymphocytes of the transplant recipient that are involved in the rejection process to a toxin; and exposing the mammal to the toxin to selectively destroy the sensitized alloreactive lymphocytes to a greater extent than non-sensitized cells of the mammal. This method induces donor specific tolerance in the transplant recipient, i.e., acceptance of the new organ or tissue without suppression of the rest of the recipient's normal immune system.
