Abstract: The invention relates to long-acting nitrous acid compositions that disinfect inanimate surfaces and animal tissues, and that can be used to treat diseases and wounds. Compositions of the invention are single-phase, metastable nitrous acid solutions that exhibit enhanced germicidal efficacy and can have an effective lifetime exceeding several years. Compositions of the invention have a wide variety of applications that include, but are not limited to, teat dips, oral rinses, instrument sterilization, and disinfection of food.

Abstract: The present invention is directed to a method of inducing the body to produce an antibody against the region of the CCR5 receptor in wild type individuals, that is affected by the delta 32 deletion and vaccines for producing said antibody. The antibody is produced is by treating the individual using a vaccine consisting of a polypeptide and its derivatives.

Abstract: The present invention relates generally to compositions and methods for the use of nitrous acid solutions to disinfect inanimate surfaces and animal tissues, and to treat diseases and wounds. More specifically, the invention deals with the partial and selected conversion of nitrite ion to nitrous acid in order to optimize the germicidal efficacy and duration of the nitrous acid consistent with the nature of the intended application.

Abstract: A composition is used as a reagent in a method for measuring Antistreptolysin O (ASO) in a blood sample. The composition contains Streptolysin O (SO) at a pH outside the range of its hemolytic activity, e.g., outside the pH range of 5-9. At that pH the SO is reversibly inactivated while maintaining its hemolytic capacity. The composition is employed to measure ASO by mixing one or more samples of non-hemolyzed blood or serum with one or more known quantities of the composition with a known hemolytic capacity, incubating each mixture to allow reaction of any ASO in the sample with the SO, restoring the hemolytic activity of the SO by adjustment of pH to permit lysis and detecting the presence or absence of lysis in each sample.
