ABSTRACT: After storage for more than one year the SCN(-)-content of udder lymph was not changed seriously, but in blood serum and mainly in milk, there is an evident decrease. In lactational cows with healthy udders the SCN(-)-content of blood plasma is higher than in milk (in average twice). There is no difference of the SCN(-)-content of the four udder parts of healthy cows. Decrease of milk production (10. to 13. lactational month) causes an increase of the SCN(-)-content of the milk, it is not changed in subclinical mastitis. In lactational cows with healthy udders the SCN(-)-content of udder lymph is nearly triple higher in average than in milk of the corresponding quarter of the udder. The existence of a common compartment of SCN- in blood and udder lymph is assumed, which is separated from them of the milk by the blood udder barrier.

ABSTRACT: The following serum levels of thiocyanate (SCN-) were found in game: roe 6.6 +/- 4 mg/l, red deer 5.5 +/- 3.2 mg/l, fallow-deer 5.1 +/- 2.8 mg/l, and wild boar 4.8 +/- 4.5 mg/l (variation 0.6-32.6 mg SCN-/l). These levels are distinctly higher than in domestic animals under stall-feeding with exception of mast calves which were fed milk-substitutes. The SCN- serum level of calves, sheep and horses reach at pasturing nearly the level of game. The higher SCN- serum level of cloven-hoof game resp. by pasturing of domestic animals is caused by higher alimentary SCN- intake.

ABSTRACT: Thiocyanate (SCN-) concentrations in serum samples of 32 cystic fibrosis (CF) patients, 30 controls as well as 23 heterozygotes (parents of CF patients) were investigated, because SCN- influenced viscosity of secretions, membrane functions as well as nonspecific and specific defense processes. CF patients showed little smaller SCN- serum levels, but the differences were not statistically significant. There were remarkable smaller values for CF patients with most serious clinical conditions due to severe pulmonary changes.

ABSTRACT: The testing of a SCN- dose (32 mg NaSCN/kg oral 21 d long) which is about 100 fold above the alimentary SCN(-)-uptake on guinea pig has shown neither histologic/morphometrical nor clinical clue to thyrostatic effect. In 6 regions of the GDR (1,349 persons) has not been secured epidemiologically any relationship between SCN- serum level as well as SCN- urine level and goiter. The partly in the tendency low increase of SCN- level by patients with bland goiter was always under the levels of smokers without goiter, exceeded indeed the threshold of significance in the area of Werdau. In the industrial agglomeration areas the I(-)-SCN(-)-quotient at the most unfavourable cases ran to 3.5 (Halle, smoker, struma), was consequently close to the critical level of the goiter risk.

ABSTRACT: The manufacture of a liquid membrane type thiocyanate ion selective electrode on the basis of crystalviolet thiocyanate or methylene blue thiocyanate solved in nitrobenzene is described. This electrodes are available for the determination of the thiocyanate ion in agents with high levels on chlorid or protein, for instance in serum. Thiocyanate levels in serum from smokers and nonsmokers determinated by this electrodes differ significant from values that were obtained by the barbituric acid method, but they were in good agreement with values determinated by ion exchange chromatography. It can be assumed that its possible to ascertain the part of the dissociated thiocyanate by means of the ion selective electrodes and the ion exchange chromatography.

ABSTRACT: Thiocyanate (previous designation rhodanide, SCN-) is a physiological substance which is ubiquitously spread in the animate nature. As an essential constituent of cell it participates in important physiological resp. biochemical processes. From the hygienic and microbiological point of view the occurrence of SCN- as environmental factor, its alimentary significance and its vitalizing effect (stimulation of nonspecific and specific warding off, stimulation of proliferation, protective effect at toxic loading) are of interest for the fundamental and applied research.

ABSTRACT: For the improvement of the registration of data by assessment of mutagenic risk the analysis of sperm-head abnormalities have been rendered as a suitable at indirect evidence of mutagenic potency. The reproduction of the results is well. The sensitivity of the test is high. The quantitative evaluation of genotoxic effects is possible. By reason of comparatively low methodical expense the screening investigations of species mouse are suitable, before more expensive tests will be accomplished for the elucidation of the mutation type. At 35 day-long intraperitoneal application the double number of sperm head abnormalities was approximately induced through Wofasteril (dose refer to main agent peracetic acid 2.6 mg/kg bw/d) and about 1/3 through cyclophosphamide (dose 25 mg/kg bw/d). With a 50% reduction of Wofasteril dose the mutagenic threshold-concentration was too low. The phenolic disinfectant Wofasept caused only slight no significant increase of the rate of sperm-head abnormalities (doses refer to the content of compounds, for Chlorocresol 1.6 mg/kg bw/d, for Clorofen 0.7 mg/kg bw/d and for detergent 4.8 mg/kg bw/d).

ABSTRACT: A survey is given of the alimentary ingestion, metabolization and elimination as well as of the biological significance of thiocyanate (SCN-) in the mammalian organism. SCN- is an important nutritional factor since it influences essential bodily functions, e.g. immune response. Its analytical determination in vegetable and animal foodstuffs may be considerably affected by the reversible binding of SCN- to protein molecules and by natural products, e.g. amino acids and cyanide, from glycosidic precursors, which interfere with the reaction with bromine. This will be combining paper chromatography with gas chromatography. Except Brassica species which are relatively high in SCN- in glycosidic combination, vegetable foodstuffs contain nearly 0.1-1.3 mg SCN-/kg fresh material; animal foodstuffs, e.g. beef, contains 0.5-0.7 mg SCN-/kg. Balances calculations have shown that in non-smokers the average alimentary ingestion ranges from 1.8 to 5.2 mg SCN-/d.

ABSTRACT: By means of fluorescence and absorption measurements the authors studied the interaction of the protein human serum albumin with relatively low concentrations (up to 5 mmol/l at the most) of thiocyanate ions. Such concentrations lead to a slight quenching of the tryptophan fluorescence in human serum albumin. The effect of thiocyanate is not due to an overall action on the protein (as sometimes observed with higher thiocyanate concentrations), but to a local interaction of the fluorophore tryptophan with the neighbouring anion-binding site which is occupied by thiocyanate.

ABSTRACT: On verifying methods for the determination of thiocyanate in biological materials, we started from the technique as described by Boxer and Rickards [5]. In different methods, the accuracy of the data obtained is affected by the deproteinization process or interfered with iron (III) ions or pyridine/benzidine, the deproteinization process being the decisive factor. This holds true especially in respect of interfering factors that remain in the supernatant (low-molecular amino compounds) and in respect of the coprecipitation of thiocyanate, the nature of the respective biological material playing an important part in both cases. At higher thiocyanate concentrations, pretreatment with a denaturing agent that is commonly used to deproteinization of human and bovine sera involves a small loss of thiocyanate due to coprecipitation. In case of high demands on reproducibility and accuracy of the analytical results, and in case of special analytical problems, isolation of thiocyanate is absolutely necessary (chromatography on Sephadex, aeration after conversion to hydrogen cyanide). Gas chromatography is suited for determining thiocyanate in whole blood.

ABSTRACT: Paper chromatographic separation of thiocyanate is the first step in determining non-bound thiocyanate in homogenized animal and vegetable foods and in human serum. The thiocyanate eluated from the paper chromatogram is brominated and then determined as cyanogen bromide using a gas chromatograph equipped with an electron-capture detector. Interfering substances (mainly ethanol-unprecipitable protein components, amino acids and cyanide from glycosidic precursors) are eliminated by this procedure.

ABSTRACT: Mice immunized with sheep red blood cells produce more direct plaque-forming cells, estimated with the hemolytic plaque-technique, during the primary immune response if they receive in that time 150 mg NaSCN/kg body mass with the drinking-water every day. The thiocyanate quantity of serum in immunized animals is higher than that in non-immunized animals. The titers of antibodies estimated by the hemagglutination test is about 1 titer step higher in thiocyanate-treated animals than in non-thiocyanate-treated animals. That applies also to the secondary immune response, in which course thiocyanate was not supplied. It is possible, that for instance a greater number of memory-cells was produced during the primary immune response in consequence of the thiocyanate application. Studies in similar arrangement with guinea-pigs confirm these statements in certain parameters.

ABSTRACT: Since the amino acids and protein components remaining in the supernatant after protein precipitation react with bromine to give cyanogen bromide just as thiocyanate, they interfere with the determination of human and animal sera by the Aldridge method. This interference is widely eliminated by hydrochlorination of the amino acids or by reduction of the redox potential of bromine in an acid medium.

ABSTRACT: In vitro and in vivo experiments have been carried out to elucidate the metabolism of 2-iminothiazolidine-4-carboxylic acid (ITC). By using 35S-ITC, the formation of 35SCN as well as of 35S-containing ITC metabolites could be excluded. As compared to the findings from control animals, the serum thiocyanate levels determined in guinea-pigs after oral administration of ITC were unchanged.
