Association between fibrinogen plasma levels and platelet counts in an outpatient population and in patients with coronary heart disease.

Although numerous studies concern fibrinogen (FBG) associations, the relationship between platelet (PLT) count and FBG plasma levels has yet to be completely investigated. The present study concerns the association between FBG plasma levels and PLT count in 5891 patients (2831 men and 3060 women) attending our outpatients' laboratory. Of these, a subgroup of 4116 patients (1899 men and 2217 women) with normal values of the parameters investigated was selected.

Antithrombin III metabolism in the pulmonary vessel endothelium.

In 85 patients undergoing aorto-coronary bypass for atherosclerotic coronary disease, we measured the antithrombin III activity levels and the thrombin-antithrombin III complex concentrations in blood from the pulmonary and the radial arteries, taken before the aorto-coronary bypass procedure, with the aim of investigating the role of the pulmonary endothelium in the metabolism of the inhibitor. Results showed significantly lower mean antithrombin III activity levels, expressed as a percentage of normal plasma, in blood from the radial artery with respect to levels from the pulmonary artery (0.78 +/- 0.

Bisphosphonate treatment in ochronotic osteoporotic patients.

In ochronotic patients, abnormalities in bone metabolism leading to increased bone loss have been reported. Therefore, we attempted antiresorptive therapy to (almost) partially reverse bone loss in four out of five osteopenic or osteoporotic ochronotic patients, two men and two women, aged 56-82 years. Each patient was treated with a 70-mg tablet of alendronate weekly and 1,000 mg/day of elemental calcium, such as gluconolactate or carbonate, throughout 24 months.

Fibrinogen metabolism in the lungs.

The aim of this study was to evaluate the role of the pulmonary vessel endothelium in the metabolism of fibrinogen (FBG), by measuring the FBG, D-dimer, and fibrin(ogen) degradation product levels in the blood from pulmonary and radial arteries from 99 patients undergoing aortocoronary bypass. For comparison, protein C, protein S, and factor VII, were also measured. The results showed, with respect to the pulmonary arterial blood levels, significantly lower FBG levels (3.

Age related prolactin secretion in men after fentanyl anaesthesia.

The aim of this study was to investigate the role of age in the hormonal response to opiate anaesthetic fentanyl. In 90 patients undergoing aortocoronary bypass, 59.6 +/- 9.
