Methacycline hyperpigmentation: a five-year follow-up

A five-year follow-up is presented of a unique material of patients who acquired a greyish black hyperpigmentation during long-term methacycline therapy for chronic bronchitis. The melanosis disappeared in cases in which tetracycline therapy was discontinued during the observation period but not in those in which doxycycline had been substituted. In two autopsy cases pigment deposits were also found in cartilage and atherosclerotic lesions. Overall clinical and microscopic findings suggest a similarity to the pigmentation occurring in iatrogenic ochronosis.</jats:p

Hydrolysis of lactose in milk and whey with minute amounts of lactase

SummaryA method for lactose hydrolysis in sterile milk or whey with Saccharomyces lactis lactase is described. The properties and stability of this enzyme are very favourable for use in milk and neutral whey. The long shelf life of sterilized milk and whey products is utilized for a prolonged incubation time – one to several weeks – at room temperature. Thus, minimal amounts of enzyme are needed which makes enzyme costs very low.</jats:p

Stories around food, politics and change in Poland and the Czech Republic

This study of the politics of food production/consumption in Poland and the Czech Republic brings together food and post-socialist studies. The food stories explored in the paper, relating to packaging, restaurant dining, self-provisioning and the emergence of an organic food sector, open up the politics of everyday life in these significant cases. We show that there are diverse responses to 'transition' that are resistant or alternative to dominant narratives of linear progression towards Western 'normality'. This finding is of wider significance at a time when debates about globalization and sustainability are promoting searches for alternative economic forms and practices
