Summary: The aluminium (Al) content of soft drinks from Al cans has been measured during 12 months of storage, by the graphite furnace atomic absorption spectrophotometry (GFAAS) method. The results show that the Al content in all soft drinks increased during the whole storage time. This increase was a result of dissolution of Al from the can wall due to the presence of aggressive ingredients in the soft drinks, mainly acids. The Al content rose with increasing acid concentration and decreasing pH value of the soft drinks. The evaluated possible daily intake of Al (0.8 mg) through consumption of these drinks was practically negligible in relation to total dietary Al intake, as well as to tolerable daily intake. Thus, soft drinks from Al cans are an insignificant source of dietary Al intake and it appears that the Al intake from this source should not be a cause for concern in regard to Al toxicity for the human body.
Keywords: Aluminium, soft drinks, aluminium cans

Summary: Aluminium levels in human milk in the winter period of 1992/93 ranged from 0.004 mg/L to 2.672 mg/L, the mean value was 0.378 mg/L. The nursing women were divided into several groups, according to the results of the questionnaire, i.e. according to their social status (if they were refugees or not), number of deliveries, post partum day, the weight they put on during pregnancy, their age, and smoking habits. The mean levels of aluminium for each group were presented. The measurement of aluminium was done by graphite furnace atomic absorption spectrophotometry.

Summary: The effect of season and species of plant on the ash and chromium (Cr) content of honey was studied. There were four types of honey : sunflower, acacia, floral and wild floral. In total there were 80 samples. The botanical origin of the honey was determined by microscopic analyses of pollen as well as the organoleptic properties. The Cr content was measured by flame atomic absorption spectrophotometry. The average Cr content in two consecutive seasons for all species was 0.121 ug/g wet weight, and 0.1515 ug/g dry weight. For sunflower, acacia, floral and wild floral honey the mean values were 0.103 ug/g, 0.152 ug/g, 0.125 ug/g and 0.098 ug/g wet weight and 0.1305 ug/g, 0.1883 ug/g, and 0.1603 ug/g and 0.1206 ug/g dry weight, respectively. The average ash content in all 80 samples was 0.141 %. There was a statistically significant (P<0.05) influence of season on the ash content as well as interaction of species and season on the Cr content.

Summary: This paper discusses the results of investigations of contamination with aflatoxin - producing fungi and aflatoxin B1 affecting 545 samples of wheat grains, 475 samples of intermediate products of wheat grain being milled to flour (like middlings) and 238 samples of flour. A significant contamination with moulds was detected in analyzed samples. Although Aspergillus (34.87 %) and Penicillium (32.37 %) dominated, other types were also present, e.g., Cladosporium, Fusarium, Mucor, Alternaria, Rhizopus, Absidia and Trichoderma (listed in order of frequency). The presence of Aspergillus flavus, the known aflatoxin producer, was detected in 9.94 % of analyzed samples. Isolates of A. flavus were capable of producing aflatoxin B1 under favourable conditions. Aflatoxin B1 was found in 76.8 % of samples contaminated with A. flavus. The highest contamination with aflatoxin B1 was detected in wheat grain samples (mean value of 16.3 ug/kg) and in intermediate products of wheat grain being milled to flour (mean value of 11.13 ug/kg). Contamination was lower in flour samples (mean value of 4.13 ug/kg). With regard to proposed standards given by the FAO and WHO, under which the content of aflatoxin should not exceed 30 ug/kg in food products, only two of 96 samples did not meet these criteria.

Summary: The effect of dietary fat on the composition of lung fatty acids was studied in Fischer rats fed two experimental semisynthetic, isocaloric diets containing different qualities of fat (low fat diet (LFD) and medium-chain triacylglycerols diet (MCTD)). The effect of MCTs preparation on the lung phospho- and neutral lipids manifests itself as a change in the degree of saturation expressed as a ratio of saturation index (RSi) MCTD vs CD. The saturation increased; in neutral lipids by 70%, in phosphatidylcholine fraction by 152.6%, and in other phospholipids by 39.5%. The results obtained using LFD on fatty acid composition of lipids showed the effect of desaturation expressed as a ratio of desaturation index (RDi), in phosphatidylcholine fraction - 1.95. The observed effect of desaturation was a consequence of administered LFD, which contains a lower amount of essential fatty acids, which strongly affects the conversion of palmitic into palmitooleic acid. The LFD can be useful as a carbohydrate diet in a special clinical situation only if enriched with a certain amount of essential fatty acids, especially linoleic acid.

Summary: The aim of this investigation was to study the effect of a short-time medium-chain triacylglycerols diet (MCTD) on lipids (particularly of fatty acids) of the rat kidney. Two groups of rats (Fischer strain) were fed during 14 days a MCTD (18.7% MCTs, 16.5 kJ/g dry matter) or an isoenergetic control diet (standard rat chow). Total lipids were isolated and separated into particular lipid classes by thin-layer chromatography. No essential differences in the distribution of analyzed lipids (cholesterol, cholesterol ester, triacylglycerols, free fatty acids, phosphatidylcholine, phosphatidylethanolamine and sphingomyeline) were noticed after a MCTD. The results showed no changes in the concentration of total neutral lipids, but slight changes appeared in the concentration of the particular classes of neutral lipids. Concentrations of cholesterol and cholesterol ester were decreased approximately 14% by MCTD feeding, at the same time, the concentration of triacylglycerols, free fatty acids and esters of fatty acids was increased by 4%. The ratio of free cholesterol to total phospholipids (C/P) decreased (17%) after MCTD. The data indicate a significant increase in fatty acid saturation (expressed as a saturation factor (Sf)) affected by MCTD. Both of the mentioned data (C/P ratio, Sf) and some additional one reported in this paper, suggest, that MCTD can affect the membrane fluidity although at the present time it is not possible to judge whether or not such effects could change the physiological function of the kidney.

Summary: The effect of low fat diet (LFD) on the composition of fatty acids of rat lung lipids was investigated. The LFD used was basically composed as follows: protein 11.94%, carbohydrates 75.33% and fat 0.66%. Control diet (CD) was isoenergetic (15 kJ/g dry substance). During 14 days of the study, experimental animals had free access to food and water. Upon the completion of the experiment, the animals were sacrificed and total lipids (TL) extracted from the lungs and isolated with chloroform-methanol. In CD and LFD, 0.54 mg TL/mg protein and 0.35 mg TL/mg protein, respectively, were obtained. Total lipids were separated into individual lipid classes by thin-layer chromatography. The following lipids were isolated: triacylglycerols (TG), free fatty acids (FFA), phosphatidylcholine (PC), phosphatidyl-ethanolamine (PE), sphingomyeline (SPH) and cerebrosides (CRB). The composition of fatty acids of particular lung lipids was determined by gas chromatography. Results of the qualitative and quantitative analysis of fatty acids of particular lung lipids showed a marked increase in desaturation after LFD as compared to control diet. This particularly refers to C16 fatty acids:PE 143.5%, PC 95.6% and TG 66%. In C18 fatty acids, desaturation was considerably lower, and was most pronounced in case of SPH (30.8%). The results obtained indicated LFD to stimulate desaturation of the lung glycerophosphatide fatty acids, which may reflect on the composition of pulmonary surfactants and cellular membranes. ??

Summary: The level of toxigenic moulds and mycotoxins was analyzed in 62 samples of medicinal plant material and 11 herbal tea samples. The most predominant fungi detected were: Aspergillus, Penicillium, Mucor, Rhizopus, Absidia, Alternaria, Cladosporium and Trichoderma. Aspergillus flavus, a known producer of the aflatoxin mycotoxin was present in 11 or 18% of the 62 medicinal plant samples and in 1 or 9% of the herbal tea samples. The medicinal plant samples, contaminated with A. flavus were also analyzed for the mycotoxins aflatoxin, ochratoxin and zearalenone; ochratoxin was found in one of the 7 samples analyzed. This study suggests that medicinal plant material and possibly herbal teas, if stored improperly allowing for mould growth, should be analyzed for mould and mycotoxin prior to use.

Summary: Modification of protein-gliadin by phosphine (PH3) has been investigated. As a substrate for investigation, gliadine was isolated from wheat. Phosphine is a pesticide used for wheat protection against insects. Gliadine contains 4 different subunits: alpha, beta, gamma and omega. Protein concentration was determined by the Lowry method. Subunits of gliadine were determined by the Weber and Osborn method using SDS-gel electrophoresis. The investigations detected changes in beta-subunits of the PH3-treated gliadine as compared to the not treated protein. Beta-subunits appeared on the electrophoregram in two fractions. It is well known that gliadine beta-subunits contain relatively a high percentage of disulphide cross-links. Phosphine is a strong reagent that causes reduction of disulphide bonds. Two fractions of beta-subunits can be explained as being structure changes on disulphide bonds by PH3.
Keywords: Gliadine modification, phosphine
