Renal blood flow and function during neuroleptanaesthesia and at elevated intravesical pressure. An experimental study in the pig.

During two hours of neuroleptanaesthesia in five pigs, renal blood flow was unchanged, whereas renal vascular resistance and the mean arterial blood pressure increased. The glomerular function was not significantly altered. The tubular function was moderately impaired. The intravesical pressure was successively elevated in seven pigs. This caused no changes in renal blood flow. The renal vascular resistance increased parallelled by a slight increase of the mean arterial blood pressure. Both glomerular and tubular function decreased when the intravesical pressure was elevated to 50 mm Hg or above.

Renal blood flow and function at elevated ureteric pressure. An experimental study in the pig.

The unilateral ureteric pressure was successively elevated in five piglets. Bilateral studies of renal blood flow and related parameters (cardiac output, renal vascular resistance, mean arterial and mean venous blood pressures) revealed no significant changes. At a unilateral ureteric pressure of 10 mm Hg, there was a temporary decrease in the renal vascular resistance in both kidneys concomitatnt with an increase in renal blood flow. Glomerular and tubular function decreased successively as the unilateral ureteric pressure was increased. At a retrograde pressure of 75 mm Hg, some renal function was still preserved, probably due to pyelolymphatic backflow.

Effect of glucocorticoids on release of lysosomal enzymes in liver ischemia and hemorrhagic shock in pigs.

The effect of glucocorticoids on the release of lysosomal enzymes was studied in liver ischemia created by dearterialization and in hemorrhagic shock in pigs. In shock the treatment with glucocoticoids suppressed the release of beta-glucosidase and beta-galactosidase into the circulation. The release of S-GOT was also suppressed in the treated group. However, a contrary effect was observed in liver ischemia indicating that glucocorticoids might even be harmful to the dearterialized hypoxic liver. Provided the plasma increase of acid hydrolases can be interpreted as quantitative signs of cell damage, the findings indicate that glucocorticoids may be of benefit in shock but not after hepatic dearterialization.
