Abstract: Procedures are disclosed for eliminating immune competent cells from a population of human epidermal cells. The cells free of immune competent cells are used for growing tissue sheets suitable for transplantation to recipients unrelated to the donor.

Abstract: The invention describes a process for culturing proliferating aggregates of plant cells, which comprises (a) uniformly plating isolated protoplasts, or isolated cells regenerated from protoplasts, in or on an agarose-solidified culture medium, and/or (b) cutting this pretreated and solidified culture medium into segments, transferring said segments to a liquid nutrient solution and continuing culturing in both cases until the cell aggregates have attained the desired size.

Abstract: A fibrinolytic activity enhancer for signal-chain pro-urokinase comprising plasminogen as an active ingredient is disclosed. The fibrinolytic activity enhancer of the present invention enhances the fibrinolytic activity of single-chain pro-urokinase without causing systemic fibrinolysis. Thus, it is highly useful in the treatment of thrombosis and obstructive diseases.

Abstract: A new glycopeptide antibiotic UK-68,597 can be prepared by submerged aerobic propagation in aqueous nutrient media of Actinoplanes sp. ATCC 53533. The antibiotic and its cationic salts are active against a variety of microorganisms and are effective in controlling coccidiosis, enteritis, swine dysentery and theileriosis as well as being effective in promotion of growth and/or improving efficiency of feed utilization in poultry, swine and ruminants.

Abstract: Method for producing powder-based solid cosmetic by mixing powdered cosmetic ingredients and organic bentonite with a volatile chlorofluorohydrocarbon-containing solvent and then shaping and drying the mixture. This method produces makeup cosmetics having no oily, sticky feeling and having excellent adhesiveness.

Abstract: An improved amino acid enriched cardioplegic solution adapted for use in preventing and treating heart muscle damage due to regional ischemia. The solution includes a calcium ion concentration of between about 50-300 umol, a metabolizable substrate concentration of 400-1000 mg % and an osmolarity of between about 400-500 mOsmols.

Abstract: A medical composition which contains a tissue Plasminogen Activator (tPA) in combination with meglumine or a salt thereof.

Abstract: The present invention relates to physiologically active substances extracted from infected tissues inoculated with a poxvirus. The substances of the present invention have excellent actions to improve blood flow and recover functions of diseased tissues, thus are useful as drugs for various diseases caused by blood flow disorders.

Abstract: External preparations of 1 melanogenesisinhibitory agent contain, as active ingredients, a placental extract of pregnant cows and kojic acid or a derivative thereof. The placental extract of pregnant cows is a very effective melanogenesis-inhibitory substance, which acts through a mechanism different from that of the known extract of fully-matured human placenta and markedly diminishes the overall activity of tyrosinase isozymes (T.sub.1, T.sub.2 and T.sub.3). The external preparations, which utilize the synergistic effect between this unique substance and kojic acid or a derivative thereof (a known melanogensis-inhibitory substance), are effective for the relief and prevention of pigmentation diseases, such as liver spots.

Abstract: A vaccine for protecting against a disease caused by a microorganism which does not synthesize nucleic acid precursors such as a Micoplasma organism, which contains nuclease and/or a nuclease fragment or derivative which produces antibodies which recognize nuclease secreted or available on the surface of the microorganism against which protection is to be afforded. A vaccine may also be prepared from an antibody or fragment or derivative thereof which recognizes such nuclease of such microorganism.

Abstract: Prolonged parenteral release of a bioactive polypeptide at desirably effective levels can be achieved using novel compositions in which the polypeptide is present in a biocompatible oil in an unusually high proportion such as at least about 10% by weight. Also disclosed are certain metal-associated somatotropins that are useful for prolonged parenteral release of such somatotropins.

Abstract: A method is provided for preparing D(-)-.beta.-hydroxyisobutyric acid by fermentation employing the method and/or ethyl esters of isobutyric acid, the methyl and/or ethyl esters of methacrylic acid, isobutyl isobutyrate and/or isobutyl methacrylate as the substrate and a microorganism of the genus Candida and other fungi. In an alternative method, the isolated cells of the various microorganisms are employed with one or mixtures of the above substrates.

Abstract: Pharmaceutical formulations for intravenous bolus injection are presented that provide thrombolytic proteins, especially "second generation" tPA molecules, in relatively high concentrations at low concentrations of excipients.

Abstract: A novel method for alleviating depression comprises implanting monoamine producing living cells in the CNS of depressive subjects.

Abstract: The method consists in subjecting the raw material (milk or retentate) to enzymatic hydrolysis by means of at least one proteolytic enzyme able to reproduce the proteic digestion occuring in vivo in the human body; recovering the thus obtained hydrolyzate; subjecting the latter to at least one ultrafiltration step on membranes able to retaining the phosphopeptides while letting the peptides pass therethrough, the ultrafiltrate thus containing the non phosphorylated peptides; recovering the ultrafiltration retentate; disaggregating the phosphopeptides in the retentate; and subjecting the latter to at least one further ultrafiltration step on membranes which do not retain the phosphopeptides, these being thus separated from the enzyme and available to be recovered as product. The resulting products are useful as dietetic aliments, therapeutic nutriments or medicaments.

Abstract: New strains of Lactobacillus capable of adhering to the gut epithelial cells of various species of animals and useful as dietary supplements.

Abstract: A melanin inhibitor comprising as the reactive component a cinnamic acid derivative of the formula (I) or (II): ##STR1## in which R' represents an acyl group having 2 to 6 carbon atoms, R.sub.1 represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group or an alkenyl group, and R.sub.2 represents a hydrogen atom, an alkyl group having 1 to 24 carbon atoms, a cycloalkyl group or an alkenyl group.The melanin inhibitors according to the invention are locally applied to affected portions such as of freckles and pigmentary deposits after sunburn without giving any stimulative or allergic troubles to the skin.

Abstract: An anti-bacterial composition contains lactoperoxidase, thiocyanate and a native oxygen donor such as a peroxide or an oxidizing enzymatic system. The peroxide or one of the components of the oxidizing enzymatic system is materially isolated from the rest of said composition by a material that is either water-soluble or water-permeable.

Abstract: A dairy cow injected with a sustained release formulation comprising bovine somatotropin, a wax, and an oil produces more milk for 28 days.

Abstract: Disclosed is milk lactoferrin as a dietary ingredient which promotes growth of the gastrointestinal tract of human infants and newborn nonhuman animals immediately on birth when added to an infant formula or given separately as a dietary supplement thus reducing chronic diarrhea, assisting in the management of short gut syndrome, and avoiding, at least to some extent, chronic intractable diarrhea of the infant.
