Table 6.

Total iron concentrations in the liver and spleen (wet tissue).

Group	n	Liver; µg Fe/mg wet tissue (± SD)	Spleen; µg Fe/mg wet tissue (± SD)
S0	3	0.6 (0.6)	0.7 (0.1)
SH	4	0.6 (0.6)	0.9 (0.2)
LL	3	6.8 (0.4)	3.37 (1.8)
LH	3	5.3 (2.3)	7.2 (7.7)
H0	3	16.3 (11.8)	9.1 (7.8)
HL	4	20.8 (13.3)	10.9 (7.7)
HH	3	18.9 (26.4)	46.3 (79.0)

Iron concentrations were measured by inductively coupled plasma mass spectrometry. The first letter of each group designation indicates the dose of nanoparticles injected: saline (S), low-dose (L) or high-dose (H) superparamagnetic iron oxide. The second letter of each group designation indicates the field strength for alternating magnetic field exposure: zero (0), low (L) or high (H) field.

SD: Standard deviation.
