Résumé
Objective To investigate clinical significance of plasma D-dimer (D-D),fibrinogen (FIB) and fibrin/fibrinogen degradation product (FDP) in patients with chronic obstructive pulmonary disease (COPD).Methods The level of plasma D-D,FIB and FDP in 150 patients with COPD and 80 healthy persons were detected,and compared.Results The level of plasma D-D,FIB and FDP in COPD patients were significantly higher than those in healthy persons[(2.16 ± 0.61) mg/L vs.(0.55 ± 0.04) mg/L,(5.88 ± 1.52) g/L vs.(3.12 ± 0.35) g/L,(7.18 ± 1.63) mg/L vs.(3.62 ± 1.55) mg/L],there were significant differences (P ＜ 0.01).Conclusion Monitoring the level of plasma D-D,FIB and FDP in COPD patients can provide reliable basis in hypercoagulable state and primary and secondary hyperfibrinolysis.
Résumé
Thrombolysis using urokinase solution is one of the effective methods in treatment of intracerebral hematoma. The present study was undertaken in order to 1) determine the most effective concentration of urokinase solution, 2) determine the most suitable time interval of irrigation of urokinase solution through the measurement of hemoglobin and FDP(Fibrin / Fibrinogen Degradation Product) of drained solution, 3) estimate the size of unresolved hematoma without taking brain CT. The results are summarized as follows : 1) The most effective and economic concentration of urokinase solution was 1000 u/ml. 2) The most preferable time interval of irrigation of urokinase solution was about one hour. 3) It was possible to estimate the size of unresolving hematoma by means of measurement of hemoglobin and hematocrit of patient, hemoglobin and volume of the thrombolysed solution, so that it was unnecessary to take brain CT for measurement of remaining hematoma.
