Figure 3. Effects of Qidantang Granule on serum inflammatory factors and renal oxidative stress factors in DKD rats. The DKD rats were administered with 50 mg/kg (low dose) and 200 mg/kg (high dose) Qidantang Granule for 9 weeks by gavage. (A–C) the expression of inflammatory factors TNF-α, IL-1β, and IL-6 in the serum of rats in each group; (D–F) the activities of LDH, SOD, and MDA in the renal tissue of rats in each group; n=6. *p < 0.05, **p < 0.01 and ***p < 0.001 vs DKD group.
