[Possible pathogenetic factors of gallstone formation in populations with a high standard of living (author's transl)].

The present work points out the variety of conditions favouring gallstone formation.--Recent research suggests that fibre-depleted, high-fat foods may lead to cholesterol gallstone formation in man. On the other side civilized diets contribute to the carcinogenesis of large bowel.--Experimental observations have indicated that hypovitaminosis C may favour pathogenesis of these diseases in a different way.

[Results of experimental studies of 51chromium-albumin kinetics following intravenous administration of Hylase "Dessau"].

Experiments on the effect of Hylase on albumin kinetics were carried out by means of 51chromium-labelled albumin on 52 wistar rats. Most of the examined tissues showed a faster exchange between blood and extravascular space by help of Hylase. That was recognized from advanced peaks of activity, their higher absolute values, and partly from the faster decrease of activity in organs and tissues. This effect did not depend on the structure of capillaries, it was observed also in bradytrophic tissues (cartilage).

[Animal experimental studies on immunogenicity, humoral response and danger of anaphylaxis in parenteral administration of hyaluronidase].

The widespread intravenous application of hyaluronidase rises questions for its potential immunogenicity, formation of humoral antibodies, and danger of anaphylaxis. In experiments on 21 rabbits and 40 rats, the authors searched for precipitating antibodies after subcutaneous, intramuscular, and intravenous application of hyaluronidase in doses equivalent to the human. Intravenous and intramuscular shots of 150 to 75 000 IU of Hylase were applied in order to test anaphylaxis. By all proving procedures antibodies against Hylase were found. The formation of antibodies occurred earlier and in higher concentrations after subcutaneous and intramuscular application. The antibodies belonged to the IgG group. One third of the animals showed anaphylactic responses at doses which were 13 to 630 times as high. 26 per cent of human patients developed antibodies after application of Hylase. No anaphylactic reactions were observed in 17 patients with antibodies when intravenous application of hyaluronidase was continued. In the dosage used in the man anaphylactic response is obviously rare though it is possible.
