Figure 4
Activity concentration histograms reflecting distributions in biopsies of normal liver parenchyma of Pt 2. Bars show the number of samples for each interval. Each histogram is split into ten activity intervals, giving different bar widths depending on the maximum activity identified. The histograms reflect biopsies at a relatively large distance from the tumour but with different mass intervals: (A) masses 6 to 14 mg, (B) masses 15 to 39 mg and (C) masses 40 to 91 mg.
