When the endotoxin-lipopolysaccharide (LPS) derived from the cell wall of gram-negative bacteria is given to the rat in vivo, there are prompt, marked decreases in glomerular filtration rate (GFR), renal blood flow (RBF) and % Na+ reabsorption (%T-Na+). However, it has not been determined whether the endotoxin itself has a direct effect on these renal(More)
Two patients who developed acute lymphoblastic leukaemia following polycythaemia rubra vera (PRV) are described. In both cases the diagnosis was made using cytochemistry and immunological markers. One patient's cells marked as T-cell acute lymphoblastic leukaemia (T-ALL), the other as unclassified (null) ALL. These cases support the concept that PRV is a(More)
Few studies have explored the effects of omega-3 polyunsaturated fatty acid (n-3 PUFA) supplementation on immune modulation in murine models of mammary carcinogenesis. HER-2/neu and PyMT mice were randomized to 2 dietary interventions: AIN-93G-based diet with 1) 11% of diet (per gram weight) as corn oil (CO) or 2) 10% of diet as menhaden fish oil plus 1% of(More)
The renal oxidation rates of glucose and lactate in the dog in vivo, in the dog cortical slice and in the isolated perfused rat kidney were compared. Lactate decarboxylation rate, on a carbon-atom basis, was from 2 to 10 fold greater than that of glucose. In the substrate-limited perfused kidney, glucose replaced only 30-40% of the substrates oxidized in(More)
Sex differences in responses to novelty with particular reference to feeding activity were examined in the present study. Male and female domestic chicks (7- and 8-days-old) were observed in a modified home cage and in an open field or novel environment after experiencing either deprivation of food or continuous access to food. Previous reports that females(More)
