    Abstract: A method of treating inflammation in patients in need of such treatment by administering an effective amount of I-A-B-C-D-E-F-G-H-II (General Formula), wherein A is Ala, Gly, Val, Ser, Thr or absent, B is Ala, Gly, Val, Ser, Thr, or absent, C is Ser, Thr or absent, D is Ser, Thr, Asn, Glu, Arg, Ile, Leu or absent, E is Ser, Thr, Asp or absent, F is Ser, Thr, Asp or absent, G is Tyr or absent, H is Thr, Arg, Gly, Met, Met(O), Cys, Thr, Gly or absent and I is Cys or absent II is Cys, an amide group, an ester group or absent. At least one of the amino acids optionally is substituted by a monomeric or polymeric carbohydrate or derivative thereof, such substitution being accomplished through hydroxyl and/or amino acid and/or amido groups of the amino acids, and wherein the peptide composes at least 4 amino acid residues, and a pharmaceutically acceptable salt thereof.

    Abstract: A method for reducing the corrosion potential of steel vessels and piping used in nuclear reactors, in particular steel vessels and piping carrying high temperature water and/or steam which has a concentration of oxygen therein. A metal hydride is added to the water, the hydrogen of such metal hydride combining with oxidizing agents, typically oxygen, present in the water to reduce the concentration of such oxidizing agents. In the preferred embodiment the metal of the metal hydride is a metal that is capable of reacting with oxygen to form a substantially non-water soluble and substantially electrically insulating compound on the surface of the steel, and in particular is one that may react with and become deposited or incorporated into a pre-existing thin oxide film layer on the surface of the steel to thereby render such thin oxide layer substantially non-electrically conducting.

    Abstract: A method for mitigating initiation or propagation of a crack in a surface of a metal component in a boiling water reactor. The method includes the step of injecting a solution or suspension of a pH-adjusting compound into the bulk water of the reactor. The compound has the property of changing the pH of high-temperature water inside the crack from a value outside a predetermined pH range (namely, pH 6.0 to 8.0) to a value within the predetermined pH range without causing any significant change of the bulk water pH. The growth rate of the crack when the crack pH is outside the predetermined pH range is greater than the growth rate of the crack when the crack pH is within the predetermined pH range.
