The aim of this study was to verify the glycaemia-lowering activity of L-arabinose. The experiment was conducted on 3 individual days, each separated by a week. At the beginning of each week rats were subjected to an oral glucose, sucrose or starch tolerance test. Five minutes prior to each test rats were gavaged with water (a control), an aqueous solution of acarbose (a positive control) and L-arabinose. There was no effect of L-arabinose on glycaemia in the glucose tolerance test, whereas it reduced postprandial glycaemia after 15 min of the sucrose tolerance test. In the starch tolerance test, the glycaemia after L-arabinose ingestion was signifi cantly decreased both at time intervals and in total. Inhibition of enzyme activity involved in starch digestion (amylase, maltase) may be suggested as the most probable mechanism responsible for the observed effects.

The balance between immunogenic and tolerogenic activities in human immune system strongly depends on microflora-induced pro-and anti-inflamatory activities. Lactic acid bacteria (LAB) are important components of microflora. The interactions of the different strains of LAB and the cells of immune system are largely unknown. To assess if LAB strains composition would have an effect on the cellular responses profile (proliferation, cytokines synthesis) peripheral blood mononuclear cells (PBMC) model system was used. PBMC were induced by three different strains of LAB: Lactobacillus acidophilus, Lactobacillus delbrueckii spp. bulgaricus, Bifidobacterium bifidum. Tested strains were mixed together, in combinations with each other (pairs) or alone. Both, the LAB mixture as well as the pairs and the single LAB strains induced low lymphocyte proliferation (about 10% of ConA-induced response). However, the single LAB strains and their combinations were quite different cytokines inducers. First, L. acidophilus was much stronger IFN- inducer than the LAB mixture, being a few times higher IL-12 stimulator than L. bulgaricus and B. bifidum. Second, L. bulgaricus and B. bifidum suppressed L.acidophilus-induced IFN- synthesis to the level equal to that induced by the LAB mixture, limiting IL-12 production by about 30% and 70%, respectively. Third, the LAB strains were good IL-10 and TNF-alphalfa inducers, irrespectively of their combinations used. We conclude that LAB strains’ pro or anti-inflammatory potentials are at least in part dependent on their composition. Low LAB mixture-induced IL-12 and IFN- production and relatively high IL-10 and TNF-alphalfa expression may represent cellular activities normally induced in vivo by a combined action of bacterial antigens. Their presence is important to limit pro-inflammatory reactions (via IL-10) and to provide protection against infections (via TNF-alphalfa).
