In a randomized, placebo-controlled double-blind study, neurophysiological methods were used to determine the effects of Neurexan on patients’ psychophysiological con dition. The administration of Neurexan was found to help them to cope better with acute stress situations. The homeopathic combination medication Neurexan consists of the components passionflower (Passiflora incarnata), oats (Aven...

Indole-3-acetic acid (IAA) was detected in the ether extracts of culture filtrates of indigotin-producing strains of the basidiomycete Schizophyllum commune. Several solvents, known to give distinctly different R(F) values for IAA, and 3 location reagents gave identical results with synthetic IAA and IAA found in the extract. Confirmation was obtained by the Avena straight growth test, split pe...

Prolamellar Body, Reaggregation, Sterols Completely dissolved lipids of a prolamellar body/primary thylakoid (PLB/PT) fraction from etiolated Avena sativa plastids were reaggregated in vitro. The analysis of the originating tubular structures showed a qualitative identity in their lipid content with that of the native PLB/PT fraction. Reaggregation experiments also showed that not all lipids co...

The usefulness of genetic identification varieties for seed quality analyses becomes important, when we suspect the presence another variety, species or even genus, based on morphological traits in purity analysis and germination test, With analyses, doubt about authenticity naked oats (Avena nuda L.) variety 'Kamil' was successfully solved. There were atypical seeds with chaff among samples th...

The activity of guanylyl cyclase (GC) responsible for cGMP synthesis was found to be predominantly located in a fraction of plasma membranes in cells of Avena sativa seedlings. The GC activity was shown to depend on light conditions of plant cultivation and seedlings age. The reversible regulation of the GC activity in etiolated seedlings by red/far red light was found. This suggests that photo...

Gibberellic acid (GA(3)) induces invertase activity within 6 hours in Avena stem segments that are incubated in the dark at 23 degrees . The maximum amount of promotion is about 5 times that of invertase activity in untreated segments. GA(3) causes significant promotion of invertase activity at concentrations as low as 3 x 10(-5) mum GA(3). The increase in invertase activity elicited by GA(3) b...
