Circumcaval ureter.

We report a case of circumcaval ureter diagnosed preoperatively by 'fish-hook' appearance on intravenous pyelogram. At surgery, patient was treated by 'Anderson Hones' pyeloplasty leaving the retrocaval segment in-situ.

Umbilical transillumination: an accurate means to diagnose minimal ascites associated with umbilical hernias.

A new bedside clinical test for the diagnosis of minimal ascites associated with reducible umbilical hernia is described. This test is based on transillumination of the hernial sac in the knee-elbow position. The test is easy to perform and has no equivocal results.

Glycolytic, hexose monophosphate shunt and bactericidal activities of leukocytes in ascorbic acid deficient guinea pigs.

It is well known that glycolytic and hexose monophosphate shunt activities of leukocytes increase during phagocytosis. The relevance of these metabolic changes to particle uptake and particle destruction is also well established. In the present study, these metabolic activities were studied to assess the phagocytic function of leukocytes isolated from ascorbic acid deficient guinea pigs.

Phagocytosis and leukocyte enzymes in ascorbic acid deficient guinea pigs.

Enzymes related to bactericidal activities of leukocytes were studied in ascorbic acid deficient guinea pig leukocytes. The activities of glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase were not affected either under resting or phagocytizing conditions in ascorbic acid deficiency. Granule bound NADPH-oxidase activity of resting leukocytes also was not altered in ascorbic acid deficiency.
