- The disaccharide 6-O-β-d-galactopyranosyl-2-acetamido-2-deoxy-d-galactose has been synthesized by transfer of the β-d-galactopyranosyl residue from lactose to 2-acetamido-2-deoxy-d-galactose utilizing the transferase activity of β-galactosidase from . To make the enzyme reusable, it was applied in an immobilized form covalently bound to Sepharose CL-4B. The yield of the disaccharide was about 20%, calculated on the amount of acetamido-deoxy-d-galactose added. The disaccharide could also be obtained by reversal of the hydrolytic activity of the enzyme, using d-galactose and 2-acetamido-2-deoxy-d-galactose as substrate. The yield in this reaction, however, was only 2–3 % under the conditions applied.

Mood effects of alcohol.

In: Psychopharmacology. - 0033-3158. ; 68:3, s. 295-9

Journal article (peer-reviewed)abstract
- Doses of 0.41, 0.63, and 0.85 g alcohol/kg body weight were administered using a double-blind Latin square design to subjects who made mood ratings at seven points in time during 3h subsequent to administration. The subjects felt more euphoric and extraverted and less tense at mainly the highest dose levels. Lower dose levels tended to induce more negative feelings. Frequent consumers of alcohol derived greater affective benefit than rare drinkers. Intercorrelations between ratings of subjective intoxication and mood variables indicated that the meaning of the variable "subjective intoxication" was different for the three dose levels and for different points in time.

Mood effects of diazepam and caffeine.
- 1980
-
In: Psychopharmacology. - 0033-3158. ; 67:1, s. 73-80
-
Journal article (peer-reviewed)abstract
- Changes in mood after administration of Diazepam and Caffeine were analyzed. Six aspects were studied: pleasantness, activation, extraversion, calmness, social orientation and control. In addition to this check list, mood ratings using magnitude estimation of selected adjectives were obtained. It was found that Diazepam decreased feelings of activation and extraversion and increased calmness. Caffeine had no clear effects on the check list, but on the magnitude estimation scale some effects opposite to those of Diazepam were observed. Men reported a higher degree of pleasantness than women after administration of Diazepam. No differences in heart rate were found. Few distinct scale values were utilized on the magnitude estimation scale and the discriminative power was found to be larger for the check list than for the magnitude estimation scale.
