Choi, Jung, and Shin: The Effects of Haedoksamul-tang on Oxidative Stress and Hyperlipidemia in LPS-induced ICR Mouse

Abstract

Objectives:

The present study was conducted to examine whether Haedoksamul-tang (HS), a traditional oriental herbal medicine, have beneficail effects on anti-inflammation and dyslipidemia in lipopolysaccharide (LPS)-induced ICR mouse.

Methods:

Twenty four 8-week old male ICR mouse were divided into four groups: normal untreated; LPS treatment only; HS 10 mg/kg plus LPS treatment; and HS 30 mg/kg plus LPS treatment. HS was orally administered per day for 2days. Twenty-four hours after LPS injection (10 mg/kg/day, i.p.), all the mice were sacrificed, and serological changes were evaluated. The levels of nuclear factor-κB (NF-κB), sterol regulatory element-binding transcription protein 1 (SREBP-1) activity and cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), tumor necrosis factor a (TNF-a), monocyte chemotactic protein 1 (MCP-1), acetyl-CoA carboxylase a (ACCa) expression were analyzed in Western blot analysis.

Results:

HS inhibited oxidative stress in the liver of LPS-induced ICR mice. The LPS-induced ICR mice exhibited the increase of NF-κB activity and COX-2, iNOS, TNF-a, MCP-1 expressions in the liver, while HS treatment significantly inhibited them. Moreover, The administration of HS significantly decreased the elevated serum triglyceride and down-regulated the levels of SREBP-1, ACCa in the liver of LPS-induced ICR mice.

Conclusions:

In conclusion, HS could have hepato-protective effects against the oxidative stress-related inflammation and abnormal lipid metabolism.
