[Comparison of nutrient media for isolation of microflora in swine dysentery].

The usability of five nutrient media - three kinds of spirolate media, thioglycolate medium and brain hearth medium - suitable for the isolation of Vibrio coli and germs similar to borrelia isolated from pigs affected by dysentery, and vibria isolated from cattle, was compared in the study. The results of comparison show that fresh-prepared substrates must be used bor the isolation of the mentioned germs in all cases and a corresponding medium must be provided. The modified spirolate media prepared from inland and imported ingredients were suitable for the isolation of the mentioned microorganisms even in the case of their use as selective media after enrichment with antibiotics.

Virological studies on gynaecological patients.

Endometrial epithelial cells and blood samples taken simultaneously with the curettage (first serum) of 138 patients suffering from menstrual bleeding disorders as well as materials obtained from 16 induced abortions, were studied for the presence of virus. Fourteen adenovirus 2 strains were isolated from samples of the patients. Endometrial epithelial cells of 35 patients were examined with immunofluorescence method and 23 of them displayed specific fluorescence referring to the presence of viral antigens, with adenovirus and herpesvirus antisera.

Glucagon treatment of experimental acute pancreatitis.

CFY male rats anaesthetized with pentobarbital were used in different groups for inducing acute pancreatitis by the retrograde injection either of 1 mg elastase, 5 mg trypsin, 4 mg lysolecithin, 10 mg Na-taurocholate in 0.2 ml volume or of 0.3 m.

Modulation of plasma aldosterone concentration by plasma potassium in anephric man in the absence of a change in potassium balance.

In studies on seven anephric patients, glucose and insulin administration before hemodialysis produced a significant reduction in plasma potassium concentration (mean reduction = 1.3, 1.7, and 1.
