Changes in the level of endogenous formaldehyde (HCHO), some N-methylated compounds (choline and trigonelline) and peroxidase activity were examined in the leaves of bean genotypes (Phaseolus vulgaris L.) with different disease-sensitivity during ontogenesis in the stressfree condition and after natural infection by Pseudomonas savastanoi pv. phaseolicola (until the appearance of lesions). HCHO, as its dimedone adduct, and fully N-methylated compounds were determined by overpressured layer chromatography (OPLC) in different developmental stages and in the infected leaves/leaf discs. Peroxidase activity was measured by a spectrophotometric method. HCHO level decreased with agetng of the primary leaf and accordingly in the leaves at different developmental stages, then increased again in both cases due to the demethylation and methylation processes. Concentration of choline and trigonelline as potential HCHO generators des creased considerably while peroxidase activity increased with agetng of the plants. Comparing the symptomless and the Pseudomonas infected leaf discs (with watersoaked lesions) we found a decrease in the level of HCHO, choline and trigonelline and there was det ectable increase in the peroxidase activity in the infected leaftissues. Our findings are in accordance with previously published results that peroxidases play an important role in oxidative demethylation processes. Our hypothesis is that the high level of HCHO in the old leaves can originate from methylated components as the result of peroxidase activity and this high level may lead to the old leaf betng resistant to pathogen. This conclusion is supported by the fact that the leaves of susceptible bean genotypes became resistant to Pseudomonas while growing older.

Calcium ionophore A23187 allowing for a calcium ion influx from an apoplast to a cytoplasm, mimicked symptoms of the frost-induced injuries in winter oilseed rape leaves, as estimated by the conductivity method. Both calcium ionophore and freezing treatment induced degradation of phosphatidylcholine. On the other hand lanthanum and gadolinum ions as well as verapamil, the inhibitors of calcium ion channels, decreased the degree of the frost-induced injuries. Lanthanum ions prevented the frost-induced degradation of PC. It is proposed that freezing alters the functioning of calcium ion channels which results in calcium ion influx into a cytosol. This in turn may lead to a degradation of cell membranes.

Dokonano przeglądu potencjalnego wpływu wybranych składników żywności na aktywność umysłową oraz ryzyko wystąpienia dysforii, demencji i depresji. Przedstawiono dowody na kluczową rolę m.in. witamin z grupy B i witamin przeciwutleniających w ochronie przed niekorzystnymi zmianami w naczyniach krwionośnych, aterosklerozą i demencją. Wskazano równie na udział choliny, alkoholu i kofeiny w funkcjonowaniu centralnego układu nerwowego oraz diety na syntezę neuroaktywnego składnika – β-endorfiny.
