Abstract Objectives This study aimed to compare spleen sizes in a hospital and a population sample using ultrasound and define normal values and factors influencing spleen size. Methods Both samples’ spleen sizes (n = 1520) were measured using ultrasound under the same conditions. Blood counts and other laboratory parameters were determined under the same conditions in both samples. Results In the hospital sample (n = 760), the mean spleen size was 114.7 mm, and in the population sample (n = 760), it was 99.1 mm. In both, spleen size in men was significantly higher than in women (p < 0.0001) and influenced by body height, weight, and BMI (body mass index) (p < 0.0001). In the hospital sample, there was a correlation with higher values for ALT (p = 0.0160), AST (p = 0.0394), AP (p = 0.0482), and ferritin (p = 0.0008) and lower values for HDL (p = 0.0091) and thrombocytes (p < 0.0001). In the multivariate analysis, higher values for AP (p = 0.0059) and lower values for hemoglobin (p = 0.0014) and thrombocytes (p = 0.0001) were found. Stratified for sex (men, women), spleen size increased with higher values for ALT (p = 0.0116, p = 0.0113), AST (p = 0.0014, p = 0.0113), and AP (p = 0.0001, p = 0.0012), and with lower values of hemoglobin (p = 0.0057, p = 0.0016), thrombocytes (p < 0.0001, p = 0.0003), and albumin (p = 0.0029, p = 0.0432). In women, there was a discordant correlation with red blood cells (p = 0.0005) and a concordant correlation with GGT (p = 0.0241), and in men discordant correlations with cholesterol (p = 0.0010) and HDL (p = 0.0404). Conclusions The already proven impact of anthropometric data on spleen size was confirmed. The role of laboratory values should be further analyzed.

Abstract We describe a kinetic immunonephelometric method for the determination of fibronectin in human plasma, used with the Beckman ICS rate nephelometer. The method is rapid and cost-effective. Two commercially available controls stated by the manufacturer to contain 200 and 295 mg/L were found to contain 198 and 290 mg/L, respectively. Mean analytical recovery was 104%. Within-run precision (CV) for normal samples was 3.8%, between-day precision 5.1%. For samples containing subnormal concentrations of fibronectin, these figures were 3.8% and 6.7%, respectively. Results by the method described here agreed and correlated well with those by a commercially available turbidimetric assay. With appropriately diluted samples, the range of measurement is 40 to 1000 mg/L. Normal values for women and men were 286 (SD 84) and 340 (SD 55) mg/L, respectively, in good agreement with values published by others.

There are a variety of ways in which the duration of the recovery period after exercise can be determined. The method most frequently employed depends upon observations of the respiratory metabolism. This method has been chosen because the respiratory changes due to exercise can be followed with reasonable ease and accuracy, and because these changes are among the last of the more obvious effects of the exercise to disappear during recovery. In addition, interesting data concerning the effects of exercise on respiratory metabolism can be collected during the determination of the duration of the recovery period when this method is used. In determining the duration of the recovery period by observation of the respiratory metabolism, it is necessary to decide when the carbon dioxide output and oxygen intake have returned to their normal values and are no longer affected by the process of recovery from the exercise. This decision has been made in a variety of ways by different investigators. Some have made one or more pre-exercise determinations of the subject's basal oxygen intake and carbon dioxide output. Recovery was said to be complete when the carbon dioxide output and oxygen consumption returned to these values after exercise. Others found that the oxygen consumption did not return to the pre-exercise level within a reasonable length of time, but remained above normal for several hours. They considered that recovery was complete when the carbon dioxide output and oxygen intake returned to a steady level after exercise, even if the level was not the same as that before exercise.

Details of uniform procedures for the routine determination of adrenaline, noradrenaline, and dopamine in urine are given. The first two compounds are determined by a trihydroxyindole method; for dopamine, a modification of the method of Carlsson and Waldeck is used. Determination of adrenaline and noradrenaline is illustrated using three different types of fluorometer. Normal values for the 24-hour excretion of these compounds in the urine of normal adults are in micrograms: adrenaline, 16.4 μg ± 1.1, noradrenaline, 54.9 μg ± 3.2, dopamine, 198.8 μg ± 36.2 (mean ± standard error). Some examples of the levels of catecholamine excretion in various clinical states are given.

Abstract The determination of plasma fibrinogen, either as clottable protein or protein precipitable with glycine or ammonium sulfate, is evaluated in terms of principles of analysis, analytic error, normal and abnormal ranges, physiologic stability, and pathologic variability of fibrinogen concentration. The quantitative comparison of analytic error, population ranges, and individual variability should permit more precise interpretation of clinical data than previously has been possible.
