Polysaccharide of Radix Pseudostellariae Improves Chronic Fatigue Syndrome Induced by Poly I:C in Mice

Table 1

Effect of PRP on CD4⁺ and CD8⁺ T lymphocyte populations in peripheral blood of mice treated with poly I:C.

Groups	Dose (mg kg^-1)	CD4^+/CD3^+ (%)	CD8^+/CD3^+ (%)	CD4^+/CD8^+
Normal	—	66.8 ± 1.1*	29.8 ± 4.0	2.4 ± 0.3*
Control	—	74.2 ± 2.2	24.1 ± 1.6	3.5 ± 0.2
PRP	100	72.3 ± 0.7	24.7 ± 1.2	2.9 ±0.1
	200	71.3 ± 3.0	25.4 ± 2.0	2.9 ± 0.3
	400	71.5 ± 1.1	26.1 ± 0.7	2.7 ± 0.1*

Anticoagulated blood 0.2 mL of each mouse was collected on day 14 after injection of poly I:C. The cell populations were analyzed by flow cytometry. Data are expressed as means ± SEM (n = 5). ^∗𝑃<.05 versus control.
