The growth N9 cells affected by SWNHs, especially in pre-treated with LPS. The 3 × 105 liver cells were seeded onto 60-mm SWNHs-coated dishes, and then all cells were countered after cultured for 48 h. The number of N9 cells pre-treated with LPS was more significant than N9 cells (A). Followed with the increasing concentrations of SWNHs, the number of N9 cells decreased significantly in a dose-dependent manner, especially in pre-treated with LPS (B) (P < 0.01). All data are represented as mean ± SEM.
