Objectives : To investigate the anti-inflammatory effects of Prunella vulgaris pharmacopuncture in lipopolysaccharide (LPS)-induced inflammatory rat model.
Methods : Sprague-Dawley rats were divided into 5 groups; normal control (n=8), LPS control (n=8), LPS+Prunella vulgaris pharmacopuncture at CV4 (CV4, n=8), LPS+Prunella vulgaris pharmacopuncture at ST36 (ST36, n=8), and LPS+Prunella vulgaris pharmacopuncture at CV12 (CV12, n=8). Pharmacopuncture was given every two days for 4 weeks followed by inflammation induction by peritoneal LPS injection (5mg/kg). Proinflammatory cytokines including interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), thiobarbituric acid reactive substance (TBARS) from blood and liver tissue were compared before and 5 hrs after inflammation induction.
Results : In CV4 and CV12 groups, plasma IL-1β, IL-6 and TNF-α levels increased by LPS injection, significantly decreased 5 hrs after injection (p<0.05). For CV12 group, plasma IL-10 concentration significantly increased (p<0.05). Liver IL-1β and IL-6 levles significantly decreased in CV4 and CV12 groups (P<0.05), while normal and LPS control groups were not significantly different in TNF-α and IL-10 levels. Plasma TBARS concentration was significantly decreased in CV12 group, while there was no significant difference among LPS control and pharmacopuncture groups for liver TBARS concentration.
Conclusions : Based on the present findings, Prunella vulgaris pharmacopuncture at CV12 may have a potentially preventive anti-inflammatory effect in an LPS-induced inflammatory rat model.
