Fibrinolytic activity of oral cyclandelate in patients with generalized atherosclerotic vasculopathy: a double-blind study.
In a double-blind study, a single dose of 1600 mg cyclandelate or placebo was administered to 10 patients with cerebrovascular and/or peripheral vascular disease, and fibrinolytic activity was evaluated before and 1, 2, 4 and 6 h after treatment. Cyclandelate induced a reduction in euglobulin lysis time, an increase in tissue plasminogen activator concentration and a reduction in plasminogen activator inhibitor, alpha 2-antiplasmin and immunological fibrinogen concentrations, but no changes in antithrombin III and plasminogen concentrations were observed. After placebo administration no significant changes were observed. After treating two patients with 800 mg cyclandelate twice daily for 14 days, 1600 mg cyclandelate stimulated fibrinolysis for 8 h. It is concluded that the fibrinolytic activity of cyclandelate has implications for the treatment of cardiovascular complications of atherosclerosis.

Determination of plasma concentrations of cyclandelate and mandelic acid in patients with generalized atherosclerotic vasculopathy treated with oral cyclandelate.
Cyclandelate, a vasoactive substance consisting of the mandelic acid ester of 3,3,5-trimethylcyclohexanol, was administered to 10 patients with cerebrovascular and/or peripheral vascular disease. Blood specimens were collected at 1-6 h after oral administration of 1600 mg cyclandelate, and the ester and acid were extracted from plasma in acid medium using n-hexane/isopropyl alcohol. The concentrations were determined by a high-performance liquid chromatography isocratic system. The highest plasma cyclandelate concentrations were detected at the third hour, whereas plasma mandelic acid concentrations were still increasing 6 h after administration.

[Action of dopamine on blood flow of the limbs and on blood viscosity (author's transl)].
The observation of several cases of gangrene in the lower limbs of subjects treated with an infusion of dopamine has encouraged the authors to study the action of the drug, in a dose capable of increasing the arterial pressure, on the blood flow in the lower limbs and on the viscosity of the blood in a group of normal middle aged subjects. A significant reduction in the values of the blood flow with a simultaneous increase in the blood viscosity was observed. There results confirm the ischemic action of the drug with the doses used at the muscular and cutaneous level in the lower limbs.

Arterial and venous blood viscosity in ischemic lower limbs in patients affected by peripheral obliterative arterial disease.
Blood, plasma and serum viscosity, packed red cell volume, and plasma fibrinogen concentration was measured in a group of 13 subjects, suffering from peripheral obliterative arterial disease of the lower limbs (stage III or IV), awaiting surgery, and in 9 control subjects, none of whom showed signs of circulatory disease of the lower limbs either by clinical examination or by instrumental measurements. The blood samples were taken from the: (a) antecubital vein; (b) femoral vein; (c) femoral artery. In the patients venous blood viscosity was significantly higher than arterial blood viscosity. No significant differences have been found between the femoral and the antecubital vein, but in the femoral vein blood viscosity was slightly higher. Packed red cell volume and plasma viscosity were slightly but significantly higher in venous blood, while no difference was seen in serum viscosity and in plasma fibrinogen concentration. In the control subjects blood viscosity values were decidedly lower than in patients and no statistically significant differences were to be found between artery and vein, even if viscosity values were lower in artery. These results support the hypothesis that an interrelation exists between hyperivscosity syndrome and vascular ischaemia-inducing diseases.
