Abstract: A process of refining zinc oxide from roasted zinc sulphide bearing concentrates comprises leaching the concentrate in an aqueous sulphur dioxide solution under controlled conditions providing selective separation of zinc from other elements contained in the concentrate. The zinc bisulphite solution so obtained is separated from the remaining solids and is heat treated, preferably with steam, to precipitate zinc monosulphite crystals, possibly after first adding zinc dust to the solution to cement out residual copper and cadmium. The zinc monosulphite is then separated from the solution, possibly washed with water, and calcined to yield purified zinc oxide.

Abstract: A dimeric protein with inhibin activity is isolated from ram reta testis fluid using reverse-phase high-performance liquid chromatography and gel filtration. The isolated molecule is composed of two chains having apparent molecular weights of about 18,000 and about 16,500 to 14,500 Daltons, as measured by gel electrophoresis, which are bound together by disulfide bonding and the longer of which is likely glycosylated. Microsequencing revealed the NH.sub.2 -terminal portion of the longer chain to be Ser- Thr-Pro-Pro-Leu-Pro-Trp-Pro-Trp-Ser-Pro-Ala-Ala-Leu-Arg-Leu-Gln-Arg-Pro-Pr o- Glu-Glu-Pro-Ala-Ala-His-Ala-Asp-Cys and of the shorther chain to by Gly-Leu-Glu-Cys-Asp-Gly-Lys-Val-Asn-Ile-Cys-Cys-Lys-Lys-Gln-Phe. This dimeric protein specifically inhibits basal secretion of FSH, but not of LH, in a rat anterior pituitary monolayer culture system, exhibiting a half-maximal effective dose of about 0.1 to 0.3 ng/ml.

Abstract: Cholecystokinin analogs useful for suppressing food intake in mammals and humans.

Abstract: Methods and compositions are described for increasing and decreasing immunoglobulin production by administering to a human or other mammalian subject an appropriate dosage of amplifier. Administration of amplifier to subjects having excessive production of immunoglobulin, namely AIDS and ARC patients, is shown as decreasing such excessive immunoglobulin production in such patients.

Abstract: This invention relates to a method of effecting immunosuppression in a patient in need thereof, comprising co-administering to said patient an effective amount of an immunosuppressive agent, wherein said immunosuppressive agent is not an ornithine decarboxylase inhibitor, and an effective amount of an ornithine decarboxylase inhibitor.

Abstract: Novel compounds, called chloropolysporins B and C, and salts thereof have antibiotic properties and would appear to be members of the class of glycopeptide antibiotics containing chlorine. They may be produced by cultivating a suitable strain of microorganism of the genus Micropolyspora, especially Micropolyspora sp. SANK 60983 (FERM BP-538). They may be combined with conventional pharmaceutically acceptable carriers or diluents for therapeutic use or incorporated into edible excipients, such as feed or water, for use as a growth-promoting agent, especially for farm animals.

Abstract: Disclosed is a method of targeting reagents to the locus of a clot, and a family of substances that have affinity for fibrin. The method and substances exploit the discovery that the binding sites on protein A from Staphylococcus aureus have a significant affinity for fibrin. These fragments, analogs thereof, and oligomers of the fragments or analogs, may be attached to fibrinolytic enzymes, remotely detectable radiation emitting moieties, or healing agents to produce reagents which have affinity for the site of a wound or intravascular clot where fibrin has been deposited. Constructs comprising repeats of truncated analogs of the binding domain have low affinity for circulating immunoglobulin and high affinity for fibrin.
