Abstract: An emulsion containing one or several polyunsaturated, long-chain omega-3 and/or omega-6 fatty acids or their pharmaceutically tolerable esters or salts, as well as usual adjuvants and additives, is used to produce an intravenously administered medicament for treating skin diseases, in particular inflammatory skin diseases, as well as diseases of the dermatitis or eczema group. Preferably, fatty acids containing 18-22 carbon atoms, as well as their pharmaceutically tolerable esters of salts, are used. These acids or their pharmaceutically tolerable esters or salts may be used in their pure form or as components of oils, such as fish oil, highly-purified fish oil concentrates, linseed oil, primrose oil, borage oil or soya oil. Specially preferred are the pharmaceutically tolerable esters or salts of said acids, in particular the pharmaceutically tolerable esters, especially those derived from eicosapentaenic acid.

Abstract: The use of a hydroxyethyl starch specification with a molecular weight M.sub.W of 110,000 to 150,000, a substitution level MS of 0.38 to 0.5, a substitution level DS of 0.32 to 0.45, and a C.sub.2 /C.sub.6 ratio from 8 to 20 for improvement of microcirculation in a peripheral arterial circulation disorder, in particular in already existing peripheral arterial occlusive disease in Stage II according to Fontaine. This hydroxyethyl starch specification can be used in suitable concentrations, e.g., as 6 wt.-% or 10 wt.-% solution, whereby these solutions optionally contain conventional adjuvants and additives.

Abstract: A hydroxyethyl starch for use as plasma expander which is obtainable by hydrolytic predegradation of a starch rich in amylopectin, partial hydroxyethylation to a specific substitution degree in the presence of alkali and subsequent hydrolytic degradation to a specific molecular weight, comprises a mean molecular weight of 60,000-600,000 and a substitution degree MS of 0.15-0.5. The ratio of the substitution of C2 to the substitution of C6 of the anhydroglucose units is 8-20 and the substitution degree DS lies in the range from 0.15 to 0.5. A process for the preparation of this hydroxyethyl starch employs 2-chloroethanol as hydroxyethylation agent. The hydroxyethylation is carried out under alkaline conditions at room temperature, the pH value held at a value of about 12 and the temperature held at a value of about 20.degree. C.

Abstract: The use of tryptophan containing oligopeptides for the treatment of cerebral disturbances in particular sleeplessness and depression is disclosed. The use of glycyl tryptophan, if desired, in combination with tryptophan itself, is especially preferred.
