Enhanced blood coagulation and enhanced fibrinolysis during hemodialysis with prostacyclin.

In the present study the effect of unfractionated heparin (UFH) (Liquemin, 750-1000 IU/h), low molecular weight heparin (LMWH) (Fragmin, 3000-7250 IU bolus), and prostacyclin (Flolan, 5 ng/kg body weight/min) on the activation of blood coagulation and fibrinolysis, induced by polysulfone membrane dialyzers during hemodialysis, was compared. Plasma levels of thrombin-antithrombin III complex (TAT), fibrin split product D-dimer, and plasmin-plasmin inhibitor-complex (PPI) were measured in the arterial and venous line of the dialyzer at the beginning and at 10, 60, 120, and 180 minutes of hemodialysis. Five patients on chronic hemodialysis treatment were investigated in a cross over study.

Evaluation of bedside prothrombin time and activated partial thromboplastin time measurement by coagulation analyzer CoaguCheck Plus in various clinical settings.

In the present study CoaguCheck Plus (CCP), a coagulation test system using whole blood, was evaluated with respect to its comparability with widely distributed conventional routine coagulation assays. A correlation of r = 0.997 (p < 0.

Acquired dyschromatopsia in combined exposure to solvents and alcohol.

Hypothesis: Does occupational exposure to solvents in combination with alcohol intake give rise to acquired color vision defects?

Method: A total of 138 individuals exposed to solvents (toluene, xylene, trichloroethylene, tetrachloroethylene) were examined using Lanthony's D-15 test and compared with 100 nonexposed controls. The extent of color vision loss was quantitatively assessed based on Bowman's color confusion index (CCI). A cumulative exposure index was calculated from the hours of exposure per day and the years of exposure.
