The mice were divided into the following treatment groups: LPS group; PDTC group; AP1 group, a dose of 0.78 mg kg−1 BW AP; AP2 group, a dose of 1.56 mg kg−1 BW AP; AP3 group, a dose of 3.12 mg kg−1 BW AP. Treatments were administrated orally 7 days before LPS challenge (15 mg kg−1, i.p.). Data are expressed as mean ± SD of eight mice. Statistical analysis was performed using the Student's t-test (significant as compared with LPS alone, * P < .05). n.d.: not detectable.
