Salicylate intolerance is defined as a nonspecific antigen-induced pseudo-allergic hypersensitivity reaction which can occur upon contact of an organism with salicylic acid, its derivatives or other related organic or inorganic acids of similar chemical structure. Since the effects of nonsteroidal anti-inflammatory drugs (NSAID) intolerance are by no means always severe or life-endangering but may just as well present as oligosymptomatic or local disorders (e.g. abdominal pain, diarrhea, we decided to evaluate the characteristics of patients with salicylate intolerance on the basis of gastroenterological case material of Medical Department I of Erlangen University. On the basis of the findings from the Erlangen interdisciplinary data register of chronic inflammatory gastrointestinal disease, the signs and symptoms of NSAID intolerance were found to constitute a diagnosis of great practical import to clinical medicine (allergology, dermatology, immunology, other disorders etc.) including gastroenterology. For approx. 2-7% of all patients with inflammatory bowel syndrome and food allergies this poses a new diagnostic and therapeutic challenge which may concern physicians from any of the disciplines involved. When presented with patients with chronic active disease who are suffering from these symptoms one should, therefore, in future give greater thought to the possibility of salicylate intolerance, all the more as there are meaningful dietetic, diagnostic and therapeutic options available for these persons.

The aim of these studies was to assess the effect of chemical conservants (FA = formic acid, PA = propionic acid, FPA+i = formic acid, propionic acid and ammonium ions) on the cell counts of yeasts and mould fungi in silage. The silage was prepared from corn (Zea mays L), cultivar Buran FAO (240). The effect of the applied conservants on silage aerobic stability was also assessed. The performed chemical analyses comprised the determination of: the content of dry matter (DM), lactic acid (LA), acetic acid (AA), ethanol, water soluble sugars (WSC), crude protein (CP) and pH. The applied preparations were found to reduce the number of yeast and mould fungi cells in all the examined silages. The growth of fungi was inhibited most strongly by the FPA+i preparation (containing a mixture of formic and propionic acids and ammonium ions). The yeast cell counts dropped (P«0.05) from 8.50 107 CFU g-1 silage in the control (CCS = control corn silage) to 2.60 107 CFU g' in silage treated with FPA+i, whereas counts of the mould fungi cells - from 15.20 104 CFU g-1 silage in the control to 4.60 104 CFU g-1 in silage treated with FPA+i. The applied conservants increased (P«0.05) the content of DM from 255.00 g • kg 1 in control to 266.60 g • kg-1 with PA, WSC from 27.10 g • kg 'DM to 30.50 g • kg -1DM with FPA+i and ethanol from 9.10 g • kg 'DM to 11.21 g • kg -1DM with FPA+i in the silage. The additives decreased concentrations of lactic acid, acetic acid and crude protein concentration after opening the barrels. The diversifying factors decreased the pH value in the examined silage. The experimental conservants were found to improve the aerobic stability of silages after 7 days of air exposure.

The white-tailed rat Mystromys albicaudatus (A. Smith, 1834) has a sacculated bilocular hemiglandular stomach. Its forestomach resembles a rumen, in that it has papillae and a high density of bacteria. This suggests that the forestomach of the white-tailed rat may be functionally similar to a rumen. Although the fermentation of fibre is very limited in the digestive tract of the white-tailed rat, the determination of total foregut fermentation relative to caecal fermentation was essential since ingested soluble carbohydrates may also be fermented by the forestomach bacteria. The present study investigated the effects of different diets (varying in proximate composition) on the pH, volatile fatty acid and lactic acid production for the various regions of the gut. The results indicate that M. albicaudatus is essentially a hindgut fermenter.

Three-year-long field and storage experiments were carried out to evaluate changes in concentrations of some organic acids in ‘Rywal’ and ‘Saturna’ potato tubers as affected by herbicides used during the growing period. The tubers were stored for 3 and 6 months at 4℃ and 8℃ at relative humidity of 95%. The weed control method did not change acid concentrations in the tubers. However, significant differences between the cultivars were seen. ‘Saturna’ had a higher content of citric, tartaric and fumaric acids, while that of malic acid was lower than in the ‘Rywal’ cultivar. There was a negative correlation between organic acids under study and malic acid after the harvest. The storage period and a lower storage temperature promoted accumulation of malic acid in both cultivars. A reverse relationship was noted in the case of other acids under study. The highest decrease, up to 70%, was found for fumaric acid assessed after 6 months of storage of the ‘Saturna’ cultivar.

We examined the interaction between the roots of Pinus sylvestris and closely related species Heterobasidion annousum s.l. (H. annosum s.s., H. parviporum, H. abietinum) that differ in host plant preference. The aim of the current study was to determine in roots the accumulation pattern of low molecular mass compounds such as catecholate and hydroxamate derivates, oxalic acid as well as iron-reduction ability of that low molecular mass compounds, that play important roles in wood degradation and they are also involved in pathogenesis. The accumulation of catechol and hydroxamate derivates increased during the early (2–6 h) and late (24–48 h) stages of interaction and similar pattern of oxalic acid accumulation were observed. The level of catecholate derivates in P. sylvestris roots that were challenged with H. parviporum or H. abietinum correlated strongly with iron reducing ability. However, when host was exposed to H. annosum s. s. hydroxamates rather than catecholates regulated iron reducing ability. The extracellular Fe3+ reducing activity was greater for H. annosum s. s. isolates than for isolates of two other species, and reduction of ferric iron may promote oxidative burst in host cell and fungal colonization. Catecholate concentration in the presence of H. annosum s.s. contributing to host cell death, confirm iron involvement in infection success.

Indigenous bacteria in the natural environment can product a wide range of metabolites more efficiently. The aim of this work was to isolate from the natural environment non-pathogenic Clostridium strains that are able to convert glycerol to 1,3-propanediol and other metabolites of potential uses in industry. The effective methods of selection and maintenance of anaerobic cultures in the laboratory conditions were also investigated. Samples were pre-cultured on modified PY medium consisted 50 g/l of glycerol. Isolated colonies growth on TSC medium were screened on the basis of morphological characters typical for Clostridium sp. Isolated bacterial strains were allowed to growth in selective media such as RCM and modified PY. The metabolites of bacteria were investigated by the HPLC technique. The bacteria strains were identified by 16S rRNA technique. The highest percentage of isolates of the genus Clostridium were obtained from excrements of animals, compost, and silages. Nearly 60% were able to convert glycerol to 1,3-propanediol. The highest capacity for utilization of glycerol to 1,3-propanediol was observed in case of the species of Clostridium bifermentans and Clostridium sordelli. The most of examined microflora were also able to short-chain organic acids and ethanol synthesis.
