NiO burden per initial body weight at the time of administration in the lung. Bronchoalveolar lavage fluid (BALF) (a), total thoracic lymph nodes (right mediastinal lymph node and left and right mediastinal lymph nodes) (b), trachea (c), and liver (d) following intratracheal NiO administration. Horizontal axis indicates the administered dose per initial body weight. The body weights of the rats were 256 ± 11 g. The column and error bars indicate the mean and standard deviation, respectively. Asterisks indicate statistically significant differences, compared with the control group (** P < 0.01, * P < 0.05). Samples with NiO levels below the quantification limit were assigned values corresponding to half the quantification limit
