Effects of prostaglandin A1 on renal handling of salt and water in congestive heart failure.

Prostaglandin A1 (PGA1) was infused at the rate of 1/microgram/kg/min in 10 patients with decompensated heart failure under conditions of water loading (5 patients) or water deprivation (5 patients). During water loading, PGA1 increased urinary excretion of sodium, potassium, chloride, calcium, and magnesium, as well as free-water clearance. During water deprivation, it increased free-water reabsorption. Gomerular filtration rate was increased slightly by PGA1 only when it was given with an infusion of hypertonic mannitol during water deprivation. This selective action of PGA1, which increased the excretion but not the reabsorption of free water, suggests its use to correct certain hypo-osmolar conditions. The site of action of PGA1 on the kidney seems to be in the tubules and mainly in the proximal tubules. These findings might be important in the understanding of the role of renal prostaglandins.

Action of cinnarizine on the hyperviscosity of blood in patients with peripheral obliterative arterial disease.

Cinnarizine, a drug capable of improving blood flow, was studied for its action on blood viscosity and its main components in patients affected by peripheral obliterative arterial diseases (POAD). Both acute and chronic administration of the drug diminished the increased whole-blood viscosity in patients, without affecting plasma and serum viscosity, hematocrit, plasma fibrinogen concentration, and plasma osmolality. Since cinnarizine also led to a significant increase of peripheral muscular blood flow, it was hypothesized that this action may be due to an increased deformability of the red cells, and may play a considerable role in the therapeutic approach to POAD.

The effects of intravenous isoxsuprine on blood viscosity in patients with occlusive peripheral arterial disease.

1 Blood viscosity is thought to be a major factor in disorders of the peripheral circulation. 2 Ten patients with obliterative arterial disease received an infusion of isoxsuprine of 20 micrograms kg-1 for 30 min. The infusion was followed by a highly significant and prolonged fall in blood, plasma and serum viscosity, in haematocrit and in plasma fibrinogen concentration. Blood lipid levels were also studied: total lipids and total cholesterol did not alter; triglyceride level was significantly lowered at the end of, and after, drug infusion. 3 There was no change in blood, plasma or serum viscosity in the four patients receiving a control infusion 2 days before the infusion of isoxsuprine. 4 The relationships between lowered viscosity and increasing peripheral tissue perfusion are discussed.
