Abstract: Small peptidic compounds containing a small and branched chained amino acid residue, pharmaceutical compositions containing at least one such compound active against glaucoma and intraocular hypertension and a method for treating glaucoma and intraocular hypertension.

Abstract: Peptide derivatives of 3-5 optionally substituted amino acids, a process for preparing the peptides, a pharmaceutical composition containing at least one peptide derivative active against glaucoma and intraocular hypertension and a method for treating glaucoma and intraocular hypertension.

Abstract: In a process for separating the dissolved and undissolved constituents of milk, a microporous membrane with a pore size in the range of 0.1 to 2 .mu.m is pretreated with an aqueous solution, dispersion or emulsion of lipids or peptides and the milk is separated on the pretreated membrane.

Abstract: Protein hydrolysates are described; they may be obtained by the enzymatic decomposition of whey protein, lactalbumin, .alpha.-lactalbumin, .beta.-lactoglobulin, lysozyme, lactoferrin or serum albumin. These products are suitable for pharmaceutical purposes.

Abstract: Compositions for increasing oxygen supply in tissue of warm-blooded animals comprising at least one vasoactive compound selected from the group consisting of (a) calcium 2,5-dihydroxy-phenylsulfonate, (b) a 3,7-dihydro-3,7-dialkyl-1H-purine-2,6-dione of the formula ##STR1## wherein AlK and AlK' are individually alkyl of 1 to 4 carbon atoms, n is an integer from 2 to 4 and R is selected from the group consisting of ##STR2## and --CH.sub.2 --CH.sub.3, (c) a pyrazolo-[3,4-d]pyrimidine of the formula ##STR3## wherein R.sup.1 and R.sup.2 are individually selected from the group consisting of hydrogen, alkyl of 1 to 8 carbon atoms, alkenyl of 2 to 8 carbon atoms and alkylcarbonylalkyl of 4 to 8 carbon atoms with the proviso that R.sup.1 and R.sup.2 are not both hydrogen and A is selected from the group consisting of ##STR4## wherein R.sup.3 is selected from the group consisting of hydrogen and alkyl of 1 to 4 carbon atoms and R.sup.

Abstract: Herpes virus was doubly mutated in two steps by treatment with phosphono formic acid and 5-ethyl-2'-desoxyuredine. In this way the pathogenicity of the herpes virus was so weakened that they are usable as vaccines.

Abstract: Novel 5-lower alkyl-2'-desoxyuridine-5'-monophosphates of the formula ##STR1## wherein R is lower alkyl of 2 to 6 carbon atoms having antiviral activity.
