Von der Nische auf den Markt. Wege und Weichenstellungen der Evangelischen Erwachsenenbildung in Sachsen

Was war und was ist ostdeutsch an der Evangelischen Erwachsenenbildung? Die Autoren, ein ehemaliger und der aktuelle Leiter der Evangelischen Erwachsenenbildung in Sachsen, sprechen über ostdeutsche Besonderheiten der kirchlichen Bildungsarbeit und diskutieren die institutionellen und gesellschaftlichen Transformationen auf dem Weg von binnenkirchlicher Bildungsarbeit zu DDR-Zeiten hin zur gegenwärtigen Situation einer staatlich anerkannten Weiterbildungsorganisation.

Serum selenium levels and blood glutathione peroxidase activities in vitiligo

It has recently been shown that patients with vitiligo can accumulate epidermal hydrogen peroxide (H2O2) in association with low catalase levels. This study examined serum selenium levels and blood glutathione peroxidase activities in 61 patients and controls. The results showed high serum selenium levels in 56% of the patients. As at least one isoform of glutathione peroxidase requires selenium for its activity, enzyme activities were also evaluated. The overall results were not significantly different compared with controls, but further age‐related analysis of the data indicated significantly lower activities in patients up to 46 years. As glutathione peroxidase can also efficiently degrade H2O2, the results of this study could indicate an additional impaired H2O2 metabolism in vitiligo

egc-Encoded Superantigens from Staphylococcus aureus Are Neutralized by Human Sera Much Less Efficiently than Are Classical Staphylococcal Enterotoxins or Toxic Shock Syndrome Toxin

PCR was employed to determine the presence of all known superantigen genes (sea, seq, and tst) and of the exotoxin-like gene cluster (set) in 40 Staphylococcus aureus isolates from blood cultures and throat swabs; 28 isolates harbored superantigen genes, five on average, and this strictly correlated with their ability to stimulate T-cell proliferation. In contrast, the set gene cluster was detected in every S. aureus strain, suggesting a nonredundant function for these genes which is different from T-cell activation. No more than 10% of normal human serum samples inhibited the T-cell stimulation elicited by egc-encoded enterotoxins (staphylococcal enterotoxins G, I, M, N, and O), whereas between 32 and 86% neutralized the classical superantigens. Similarly, intravenous human immunoglobulin G preparations inhibited egc-encoded superantigens with 10- to 100-fold-reduced potency compared with the classical enterotoxins. Thus, there are surprisingly large gaps in the capacity of human serum samples to neutralize S. aureus superantigens
