Changes on the relative ratio of liver weight to body weight and the liver index of the control rats and those received 20, 35 or 50 injections of SDNPs (2 mg/kg bw)
| Dose | Average body weight (g) | Average liver weight (g) | The percentage of absolute organ weight (%) | Liver index |
|---|---|---|---|---|
| Control group (normal saline) | 20 injections (257.25±21.5) | 9.82±1 | 3.82 | 1 |
| 35 injections (310±24.6) | 11.687±1 | 3.77 | ||
| 50 injections (335.8±17.58) | 12.35±0.9 | 3.68 | ||
| Received SiO2 NPs (2 mg/kg bw) for 20 injections | 235.83±29.34 | 9.36±1.1 | 3.66 | 0.96 |
| Received SiO2 NPs (2 mg/kg bw) for 35 injections | 272.50±18.55 | 9.34±1.1 | 3.43 | 0.91 |
| Received SiO2 NPs (2 mg/kg bw) for 50 injections | 295.17±22.93 | 9.66±1 | 3.27 | 0.89 |
