Dose-dependent induction of astrocyte activation and reactive astrogliosis in mouse brain following maternal exposure to carbon black nanoparticle

Table 2 Effects of maternal exposure to carbon black nanoparticle on litter size and offspring sex ratio

Group name	Number of dams	Number of offspring	Sex ratio (%)^a
Control (Ultra-pure water)	5	16 ± 2	47 ± 16
Low-dose CB-NP (2.9 μg/kg)	5	15 ± 2	44 ± 9
Middle dose CB-NP (15 μg/kg)	5	14 ± 2	42 ± 9
High dose CB-NP (73 μg/kg)	5	16 ± 2	53 ± 13

There were no significant between-group differences. Data are presented as the mean ± standard deviation. ^aSex ratio (%) = male/(male + female) × 100. Abbreviations: CB-NP carbon black nanoparticle
