Table 2: Body weight gain of the rats during the treatment period.

Group Body weight gain (g) Summed Mn dose (mg Mn°/animal) C3 161.7 ± 14.4 — VC3 149.9 ± 11.2 — MnL3 149.2 ± 13.9 (99.6%) 17.94 ± 0.52 MnH3 143.7 ± 23.6 (95.9%) 71.58 ± 2.93 C33 234.2 ± 19.7 — VC33 218.4 ± 20.9 — MnL33 210.9 ± 17.2* (96.5%) 28.46 ± 0.55 MnH33 195.2 ± 27.6**# (89.4%) 83.42 ± 2.95 C6 234.2 ± 25.0 — VC6 235.2 ± 15.3 — MnL6 226.1 ± 17.3 (96.2%) 44.55 ± 1.00 MnH6 211.0 ± 19.3# (89.7%) 178.43 ± 8.53

For group codes, see Table 1. The data represent group averages (mean ± SD, ) of the difference between body weight on day 0 (before the first Mn administration) and the day of sacrifice. * , **: , 0.01 versus C; #: versus VC. Percent values in parentheses represent the weight gain in the Mn-treated groups compared to that in the corresponding VC group.
