[The plasmid composition and pathogenetic characteristics of Yersinia pseudotuberculosis strains isolated from human subjects against a background of epidemic and sporadic morbidity].

112 newly isolated clinical cultures of Y. pseudotuberculosis have been studied. The strains have been characterized by the presence of plasmids and pathogenicity signs associated with plasmids.

Results of the carotid and the differential jugular compression tests in normal and glaucomatous patients.

A carotid compression tonographic test was performed in 53 normal persons and 40 patients with primary open-angle glaucoma. Fifty normal and 58 glaucomatous patients were investigated by a differential jugular compression test. In the glaucomatous eyes as compared to the normal eyes the volume changes in the eyeball were found to be significantly greater during compression of the common carotid artery and significantly less under the influence of the jugular compression test.
