Effects of carbon dots on percentage of CD3+ and CD19+ lymphocytes in spleen of BALB/c mice
Groups CD3+ (%) CD19+ (%) CD3+/CD19+
Saline 36.01 ± 1.62 58.01 ± 1.55 0.62 ± 0.04
Carbon dots
2 mg/kg 37.44 ± 0.32 57.44 ± 0.55 0.65 ± 0.01
10 mg/kg 35.12 ± 0.39 58.09 ± 0.32 0.60 ± 0.01
50 mg/kg 36.97 ± 1.81**↑ 55.81 ± 0.73*↓ 0.70 ± 0.02**↑

The effects were recorded 1 day after administration. The data are presented as mean ± standard deviations, n = 5. *P < 0.05 and **P < 0.01 compared with the saline group (control). Significant difference was calculated by one-way ANOVA using SPSS19.0.
