Data are means±s.e.m. of four rats. Values represent densities measured in fmol mg−1 tissue.
Significant difference between WKY and SHR but not dependent on age.
Significant difference between 8 weeks and 16 weeks but not dependent on strains.
Significant differences between both strains and ages.
F-values showing strain and age interaction. In that case, significant differences are between SHR and age-matched WKY (*P< 0.05; **P< 0.01; ***P< 0.001) or between 8 and 16 weeks in each strain (†P<0.05; ††P<0.01; †††P<0.001).
