Erythrocytic galactokinase and/or galactose-1-phosphate uridyl transferase activity were low in many species of marsupials. However, cataract formation was observed only in pouch-young members of these species when reared on cow's milk. The galactose tolerance of young kangaroos was found to be greatly impaired, but improved rapidly and markedly at the stage of which the definitive structure of the ruminant type of stomach as in adults is formed. The combination of high absorption of galactose and low levels of galactokinase and/or transferase thus appears to determine the predisposition of pouch-young marsupials to galactose cataractogenesis.

The effect of experimental anaemia on the levels of glutathione and glycolytic enzymes of the erythrocytes of normal and glutathione-deficient Merino sheep.

The effects of experimental anaemia on the levels of reduced glutathione (GSH) and the activity of glycolytic enzymes in the erythrocytes of normal and GSH-deficient Merino sheep were investigated. There was a rise in red cell GSH levels in both groups of sheep; the magnitude of this response was, however, quite different. When expressed as a percentage of the initial value, the rise in GSH level was 18% in normal and 263% in GSH-deficient animals. There was also an increase in the activities of various enzymes following phlebotomy but this increase was similar in the two groups of sheep.

Elbow Arthrography with the Application of Tomography.

The intra-articular structure of the elbow joint was studied in 18 patients with double contrast arthrography and tomography. All tomographic examinations were made with the hypocycloid motion. The authors feel that the disadvantages of the method, i.e., getting access to tomographic equipment, the 30 to 45 minutes required to complete the examination, and the radiation from multiple exposures needed for tomographic sections are obviated by the results: the arthrographic findings were confirmed in all 7 patients who later underwent surgery.
