Effects of carbon dots on percentage of CD3+ and CD19+ lymphocytes in spleen of BALB/c mice
Groups CD3+ (%) CD19+ (%) CD3+/CD19+
Saline 18.00 ± 1.40 28.74 ± 1.14 0.63 ± 0.02
Carbon dots
2 mg/kg 26.48 ± 0.52**↑ 33.88 ± 0.56**↑ 0.78 ± 0.02**↑
10 mg/kg 25.50 ± 0.36**↑ 35.95 ± 0.94**↑ 0.71 ± 0.03*↑
50 mg/kg 26.68 ± 0.57**↑ 29.87 ± 1.07 0.89 ± 0.05**↑

The effects were recorded 9 days after administration. 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.
