To investigate the effects of Ewomia ulmoides olivon extract on the serum and hepatic lipid status and anti-oxidant enzyme activities, male Sprague Dawley (SD) rats were given high fat diets and Eucomia ulmoides olivon ethanol extracts for 6 weeks. Rats were divided into (our groups consisting the control (C), Eucomia ulmoides oliuon extract fed group (CE), high fat diet group (CL) and the extract and high fat fed group (CLE). Eucomia ulmoides oliuon ethanol extract lowered total cholesterol, but increased HDL-cholesterol and HDL-cholesterol/total cholesterol of the serum compared to the control. On the other hand, the ratio of HDL-cholesterol/total cho-lcsterol (HTR) was increased by 55% (p<0.05). High fat diet significantly increased serum cholesterol contents, but decreased HDL-cholesterol level and HTR (p<0.05). Atherogenic index (AI) of CL group was increased by almost four times of the control (p<0.05). Triglycerides (TG) and phospholipids were also increased by high fat diet. Eucomia ulmoides oliuon ethanol extract decreased the levels of TG (p<0.05) and phospholipids (p<0.05). Although liver antioxidant engyme activities including glutathione sulfur transferase (GST), superoxide dismutase (SOD) and catalase were decreased by high fat diet, those were stimulated by the administration of Eucommia ulmoides olivon ethanol extract.

By the end of the $21^st$ century, the world population will surely far exceed the current 6.6 billion, threatening the essential requirements for life due to environmental deterioration and shortened food supply. To overcome this looming threat, we must develop new biotechnologies. There are so many known natural phenomena that we may have neglected, not perceiving them as blessings of nature. Many more remain unknown. We must examine each of them carefully since the many tricky and complicated mechanisms behind simple natural workings could provide us with attractive research targets. How then do we apply these complicated natural mechanisms to agricultural/ industrial production?.
