Intact kidney function during contralateral renal artery clamping in dogs.

Experiments were carried out on 32 Nembutal anaesthetized mongrel dogs from both sexes. After 45 min control period unilateral renal ischemia was achieved by clamping the left renal artery for 90 min. In part of the experiments (n = 8) after clamp removal 3 consecutive 45 min periods were performed.

[Clinico-allergological studies of workers in the manufacture of fodder yeasts].

The authors have examined 161 persons from the production of fodder yeasts. On the background of detailed clinical examination are performed immunoallergological studies, including skin allergologic tests with series of standard allergens and antigens of the produced culture yeasts and determined immunoprecipitants in the blood serum. Increased sensibilization is established in 34.

[Biopharmaceutic studies of a bioerodible nystatin unit].

The release of nystatin from monolithic bioerodible system with pectin was studied. The process of both system degradation and drug release was expressed with an equation of Hixon and Crowell. It was established that an increasing thickness of the system as well as an increase of drug concentration decreased the rate of erosion and the release of the active principle.
