Abstract

We investigated the effect of the phytocompound Denshici-to-Chiusei (DTS) on the atherogenesis in apolipoprotein E(-/-)/low-density lipoprotein receptor(-/-) (apoE(-/-)/LDL receptor(-/-)) mice (E0). E0 mice were fed for 16 weeks with: (1) placebo or (2) 25 mg or (3) 50 mg of DTS/day. Aortic lesions were reduced by 38% (p < 0.01) in mice fed 50 mg/day, whereas peritoneal macrophages after both dosages had a 45%-60% lower (p < 0.01) capacity to oxidize LDL and to degrade it. This was associated with reduced LDL-associated lipoperoxides and a 22% inhibition (p < 0.05) in LDL aggregation. Tumor necrosis factor-alpha (TNF-alpha) expression and immunoreactivity in the aortic media increased five-fold, but this was significantly mitigated by DTS (50 mg > 25 mg) (p < 0.05). DTS significantly attenuated inflammatory mechanisms preceding atherogenesis with reduced LDL susceptibility to oxidation-aggregation. PMID: 20370493 [PubMed – indexed for MEDLINE]
