    Notes: Abstract Superoxide dismutase activity was demonstrated for 6 strains of 3 propionibacteria species. Rather high level of superoxide dismutase activity found in propionibacteria was in accordance with high level of catalase activity reported for propionibacteria previously. Both these activities were shown to have cytozolic localization. For the first time peroxidase activity was detected in gel-fractionated crude cell extracts of propionibacteria. The ability to produce superoxide radicals in NADH-dependent oxidation system was revealed for three strains of the bacteria. The level of superoxide production by the membrane particles of the propionic acid bacteria correlated with the levels of superoxide dismutase and catalase activities and was the lowest for Propionibacterium shermanii. The ability to perform monovalent oxygen reduction during succinate oxidation was not revealed. The intact cells of P. globosum, P. vannielii, P. shermanii apparently did not excrete superoxide radicals into culture fluid during respiration.

    Notes: Abstract Rationale: The implication of CCKB receptors in cognitive processes is far from fully understood. Objective: The present study investigated the effect of propionyl-BC264, a selective agonist of CCKB receptors, in young and old rats. Methods: Cognitive functions were studied in a two-trial recognition memory task developed in our laboratory. Results: It was shown that propionyl-BC264 enhanced information processing in young as well as in old rats when injected (10 μg/kg; IP) immediately after the acquisition phase and before the retrieval trial but not before the acquisition trial. This cognitive enhancing effect was blocked by prior administration of L 365,260, a selective CCKB receptor antagonist. Conclusions: In view of the fact that BC264 is devoid of anxiogenic effects, it could be of value in the treatment of cognitive impairments associated with both normal and pathological ageing.
