Comparison Of The Results

SummaryA pair of printing scalers was used to record the information obtained by external monitoring of the isotope dilution curve following the intravenous injection of radioiodinated human serum albumin. The first scaler gives the differential count rate of the curve at increments of one second, whereas the second integrates continuously the isotope dilution curve. This recording device enabled cardiac output determinations to be calculated rapidly at the bedside without any loss in accuracy.Using this method in 15 normal individuals, the cardiac output was found to be 6.13 ± 0.73 liters/minute (Mean ± 1 S.D.), with a cardiac index of 3.36 ± 0.35 liters/minute/m2. In the same group of normals, the stroke index (stroke volume/surface area) amounted to 50 ± 7.3 ml/beat/m2.Comparison of the results of this method with those obtained by integration of the entire isotope dilution curve by an IBM 1620 computer showed excellent agreement, proving the validity of the suggested technique.

SummaryThe effect of several tissue thromboplastins on the abnormal factor X (factor X Friuli) has been investigated.The prothrombin time varied between 33.6 and 69 sec. The prothrombin time percentile values (saline dilution curve and Quick’s formula for citrated plasma) varied between 6.6 and 22% and between 10.9 and 32.8%, respectively. The prothrombin time patient/normal ratio varied between 2.24 and 4.43.The factor X level varied between 3.5 and 20% of normal.Significant correlations were found to exist between the percentile factor X level and the prothrombin time in seconds, the percentile prothrombin time values and the prothrombin time patient/normal ratio. Thromboplastins of human origin yielded the lowest factor X values namely 5% thereby appearing to be practically “inert” with regard to the abnormal factor X. Thromboplastins obtained from rabbit lung on the contrary yielded the highest values, namely 15.3%. Thromboplastins obtained from simian or rabbit brain gave values intermediate between these two extremes.
