Figure 52.
After 4 hours, urine samples were collected and
tyophilized, and tritium in the water portion was
counted in a Nuclear-Chicagoliquid scintillation
counter. From these values of total body water,
fat was estimated by the formula % fat =100
—(% TBW/0.72). The % TBW is total body
water (in kg) as percent of gross weight. Lean
body mass (LBM)was taken as the difference between gross weight and fat (kg).
The data are shown in Table 20. According to
Sin (personal communication) the values for total
body water, fat, or lean body mass are not different from averages for Caucasian subjects in the
San Francisco area. Figure 52 shows the values of
blood volume(liters) and red cell volume(liters)
plotted against total body water. Regression lines
drawn for Caucasians by Moore" andSiri (un-
published) disclose that with the exception of one
case the values of Marshallese fall far below those
described by the authors. The average red cell
volume for Marshallese is 28.3 m! per kg LBM as
compared to 35 ml/kg (Siri, unpublished).
Whether these findings represent a genetic difference or are the result of environment and/or
diet cannotbe stated at present. It is hoped that
studies will be continued in 1965 with examina-
