title: [Effects of lycopene on blood lipid and red blood cell of rat with hypercholesterolemia].
abstract: OBJECTIVE
  To study the effect of lycopene on red blood cell and the level of blood lipid.
  
  
  METHODS
  According to the level of serum total cholesterol and weight, forty-eight adult male SD rats were divided randomly into six groups: normal control (group A), fed by normal feed; hyperlipidemia group (group B): fed by high fat diet; positive control group (group C): fed by high fat diet plus 10 mg * kg(-1) * d(-1) fluvastatin sodium; lycopene groups: fed by high fat diet plus 11 (group D), 22 (group E), 44 mg * kg(-1) * d(-1) (group F) lycopene through gavage, respectively. For all six groups, the level of serum total cholesterol (TC) and total triglyceride (TG) were measured at the end of 0, 1, 3 weeks of the study by taking samples from tail vein. At the end of the experiment, RBC and HGB were measured.
  
  
  RESULTS
  After the rats were fed with high-fat feed for a week, models of hyperlipidemia rats were established. At the end of 3 weeks, TC of group A, B, C, D, E and F were (1.31 +/- 0.05), (19.40 +/- 0.54), (4.66 +/- 0.07), (7.18 +/- 0.06), (5.30 +/- 0.28), (4.49 +/- 0.23) mmol/L (F = 4395.72, P = 0.00), respectively;and TG were (0.42 +/- 0.01), (2.29 +/- 0.42), (0.69 +/- 0.03), (1.10 +/- 0.05), (0.63 +/- 0.02), (0.62 +/- 0.04) mmol/L (F = 127.26, P = 0.00), respectively; HGB were (143.13 +/- 6.33), (112.63 +/- 2.56), (124.75 +/- 3.62), (124.63 +/- 7.78), (132.38 +/- 6.41), (142.13 +/- 5.54) g/L (F = 34.14, P = 0.00), respectively; RBC were (6.75 +/- 0.60) x 10(12)/L, (5.08 +/- 0.75) x 10(12)/L, (7.14 +/- 0.82) x 10(12)/L, (5.94 +/- 1.09) x 10(12)/L, (6.18 +/- 0.36) x 10(12)/L and (7.31 +/- 0.58) x 10(12)/L (F = 10.35, P = 0.00), respectively.
  
  
  CONCLUSIONS
  Lycopene have some protective effects on red blood cells of the hyperlipidemic rats by regulating the blood lipid and antioxidant.
