All mice, except those in the ‘None’ group above, received AEF and AgNO3 on day 0 as described in Methods.
Mean (SD), mg/l.
Mean (SD),% injected dose of 125 I-labelled human SAP retained in organs at death on day 3, after intravenous tracer injection on day 2.
Median (range), histological grade of congophilic amyloid deposits assessed as in Methods.
C3 values in all mice exceeded assay upper limit and were not reassayed on dilution.
P-values are for Wilcoxon rank sum (Mann–Whitney) tests between CVF-treated and corresponding buffer-treated control groups.
