Enteral nutrition delivered via a nasojejunal tube is associated with a significant reduction in gastric residual volume, a strong trend toward improved tolerance of enteral nutrition, and an extremely low requirement for parenteral nutrition.

The active sodium transport of white cells and red cells obtained from patients with essential hypertension was impaired. Incubating white cells from normotensive subjects in serum obtained from patients with essential hypertension caused an impairment in sodium transport in the white cells of normotensive subjects similar to that found in the white cells of hypertensive patients. The impairment in sodium transport was due to a fall in the ouabain-sensitive component of the total sodium efflux rate constant. These results show that the serum of patients with essential hypertension contains a substance which influences sodium transport and that it has ouabain-like activity. They also suggest that it is this substance which causes the impairment in sodium transport in the leucocytes of patients with essential hypertension.These findings support the hypothesis that the rise in blood pressure in patients with essential hypertension is due to an increased concentration of a circulating sodium transport inhibitor which is continuously correcting a tendency for sodium retention by the kidney.

Total Kupffer cell phagocytic activity of the liver is markedly increased in rats with a high parasitemic load of malarial P. berghei infection. This is presumed to reflect an upregulation of scavenger activity phagocytosing erythrocytes and their breakdown products.
