Cumulative radioactive sterol appearance in thoracic duct lymph. Using a dual-channel isotope scintillation spectrometer, [14C]cholesterol and [3H]sitosterol disintegrations per minute were measured in aliquots of whole lymph from hourly collections. Data are expressed as percentage of accumulated radioactive sterol dose recovered in collected lymph for each animal and represent mean ± SEM (n = 7–9/genotype). Different letters denote statistically significant differences (P < 0.05) at 8 h as measured by two-way ANOVA and Bonferroni posthoc tests.
