Validity of post-proline splitting dipeptidyl aminopeptidase activities in the cerebrospinal fluid for neurologic and psychiatric diagnosis

The dipeptidyl-peptidase activity of 650 liquores cerebrospinalis was obtained by means of the substrate Gly-Pro-NHNp (Gly-Pro-4-nitroanilid) at pHs of 5.5 and 7.4. In comparison with a reference collective, the suitability of the method as a supplementary liquor parameter in neurological psychiatric diagnosis was examined. The introduction of the measurement at pH 7.4 can be particularly recommended for the distinguishing of bacterial and nonbacterial meningitis.     

Countertransference, empathy, and the analytic ideal: the impact of life stresses on analytic capability

Analysts' emotional attitudes toward countertransference issues are influenced by unduly perfectionistic ideals that are partly derived from the early period of psychoanalytic theory. Analysts' unconscious receptivity, whether of the beneficially empathic kind or the disadvantageous countertransference variety, is a reflection of a dynamic internal state. This fundamental relationship between empathy and countertransference is illustrated with examples. Important events that occur in the life of the analyst, by virtue of their impact on his own central compromise formations, cannot but affect his analytic functioning. Minor disturbances in analytic capability are commonplace and do not significantly handicap effective work.     

Effect of levels of exercise on psychological mood states, physical fitness, and plasma beta-endorphin

Aerobic exercise which resulted in a significant improvement in cardiovascular functioning had no more effect on psychological mood states than did the placebo control of participation in nonaerobic recreational games or no exercise and sport at all (N = 430 college students). Beta-endorphin levels with the 41 depressed subjects were not a biochemical link that might explain the possible influence of physical activity on depression.     

Cigarette smoking, urinary acidity, and nicotine excretion under natural conditions

For 40 males who smoked 20 cigarettes a day titratable acidity of the urine was significantly correlated with nicotine/cotinine excretion at several sample intervals, as was urinary pH, but not urinary acidity and daily cigarette consumption or serum COHB.
