The increase of net weight and coefficients of liver of mouse after intraperitoneal injection with nano-anatase TiO2suspensions for consecutive 14 days
Indexes Nano-anatase (mg/kg BW) Bulk (mg/kg BW)
0 5 10 50 100 150 150
Net increase of BW (g) 7.35 ± 0.37 8.08 ± 0.40 7.82 ± 0.39 7.66 ± 0.38 7.27 ± 0.36 7.18 ± 0.36 7.36 ± 0.37
Liver/BW (mg/g) 56.81 ± 2.84 56.97 ± 2.85 60.09 ± 3.00 63.68 ± 3.18* 65.88 ± 3.29* 71.16 ± 3.58** 61.87 ± 3.09*

Ranks marked with an asterisk or double asterisks means it is significantly different from the control (no nano-anatase or bulk TiO2) at the 5 or 1% confidence level, respectively. Values represent means ± SE,n = 10
