title: The influence of Sam-Chil-Geun (Panax notoginseng) on the serum lipid levels and inflammations of rats with hyperlipidemia induced by poloxamer-407.
abstract: OBJECTIVE
  Atherosclerosis is characterized by the progressive deposition of lipids and inflammatory process. We attempted to develop a chemically-induced hyperlipidemic mice model, using poloxamer-407 and evaluated the lipid lowering and anti-inflammatory effect of P. notoginseng compared with that of atorvastatin, an antihyperlipidemic drug.
  
  
  METHODS
  Male Wistar rats were randomly divided into 5 groups: control group without any intervention (normal), poloxamer 500 mg/kg i.p. (P), poloxamer plus atorvastatin 1.34 mg/kg p.o. (P + ST), poloxamer plus P. notogin-seng 40 mg/kg p.o. (P + NG40), and poloxamer plus P. notoginseng 100 mg/kg p.o. (P + NG100). After 3 weeks, we measured serum total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride, interleukin (IL)-1, tumor necrosis factor (TNF)-alpha levels, and reports of cyclo-oxygenase (COX)-2 and intercellular adhesion molecule (ICAM) appearances in each group.
  
  
  RESULTS
  After 3 weeks, serum cholesterol levels significantly decreased in P + ST and P + NG40 groups. Significant decrease of LDL level was only noted in the P + ST group. P + ST, P + NG40, and P + NG100 also had decreased serum triglyceride levels; however, P + ST and P + NG40 showed no statistical difference of the triglyceride lowering effect. The results of IL-1 and TNF-alpha and the appearance of COX-2 and ICAM were statistically not different in each group.
  
  
  CONCLUSIONS
  P. notoginseng 40 mg/kg showed significantly lowering effects on serum total cholesterol and triglyceride levels. We suggest a well-designed study showing the effects of regulating blood lipids with combined administration of P. notoginseng and statin-drug.
