It is abundantly clear that the incidence of all the common cancers in human is being determined by various potentially controllable external factors. This is surely the most comforting fact to come out of all cancer research, for it means that cancer is, in large part, a preventable diseases. World Cancer Research Funds (WCRF) & American Institute for Cancer Research (AICR) 1997:670 halaman

INTRODUCTION • GINGER • Zingiber family • The rhizome is commonly accepted as a source of flavor : • cooking, drinks, baking • Grows well in tropical rainforest climate • Traditional beliefs: • prevention of common cold, physiological and stomach disorders, • inflammation, diarrhea, etc (Tang and Eisenbrand, 1992)
Antioxidant capacity of ginger extract (oleoresin fractions) in • linoleic acid system > a-tocopherol (Kikuzaki and Nakatani,1993) • Oleoresin fractions gingerol, shogaol • Suppress 5-lipoxygenase or prostaglandin synthetase • (Flynn and Rafferty, 1986) • Protect TPA induced ear edema, epidermal ornithine decarboxylase • activity, skin tumor promotion in female ICR mice (Park et al, 1998) • Protect lymphocytes and hybridoma cells from induced oxidative • stress, reduced intracellular free radicals, increase natural killer • lysing function toward target cancer cells (Zakaria et al, 1999) • Increase Ca++ATPase activities in cardiac sarcoplasmic reticulum • (Antipenko, et al.1999) Scientific Reports

RESEARCH OBJECTIVES • To find out whether drinking ginger water extract can • 1. Lower plasma cholesterols • 2. Protect plasma LDL against oxidation • To find out whether the protection of LDL can prevent further • accumulation of cholesterol in macrophage
METHODOLGY • Subjects: 24 healthy male students living in the same religious dormitory • two groups: treated group and control/placebo group • Ginger drinks: • water extract, pasteurized 850C, added with sugar syrup • standardized acceptable drink • given every afternoon at 17:00 • placebo group received syrup without ginger extract • Plasma analysis: • 1. Total cholesterol (CHOD-PAP method, Boehringer-Mannheim, kit) • 2. LDL-C (PVS method, Boehringer-Mannheim, kit) • 3. HDL-C (phosphotungstic acid)
LDL isolation: • 8 ml plasma + 5 ml NaCL 0.9% + EDTA 0.01% • incubation in polyalomer tubes • Ultracentrifugation at 36.000 rpm 40C, 20 hours • Tube cutting b VLDL • LDL + LDL (d> 1.006 g/ml) • Scaled tubes + 0.1109 g KBr/ml • Mixing • Transfer to new polyaomer tubes + 4 ml KBr in NaCl-EDTA • Ultracentrifuse, 36.000 40C 24 hrs • LDL (upperpart, d , 1.063 g/ml) • LDL, dialized
LDL oxidation: • The isolated LDL was oxidized with 5 mM CuSO4 at 370C • conjugated dienes was monitor continuously at 234 nm for 30 minutes • MDA LDL analysis: • Extraction with butanol • measurement at 515 nm exitation, 553 nm emission (Conti et al • 1991)
Cholesterol accumulation in macrophages: • Plasma from one healthy male was incubated with 430 mg/ml • ginger dichloromethane extract, 1 mM a-tocopherol or none • for 3 hrs at 370C • Mouse was injected with thioglycolate • macrophages, 2-3x106, isolated from peritoneal, were incubated • in RPMI 1640 containing 1% BSA and incubated for 4 hrs at • 370C, 5% CO2 • cells were washed and cholesterol was extracted with • isopropanol • total cholesterol, esterified cholesterol, free cholesterol analysis • was done by HPLC
Figure 1. HDL, LDL, and total cholesterol, and triglyceride in plasma of male student subjects before and after treatment with ginger drink for 30 days (n=12) and those in control placebo subjects (n=12)
Figure 2. Significant protective effects of drinking ginger for 30 days in male student subjects (n=12) on resistance of the isolated LDL against oxidation by CuSO4 for 100 minute, measured by conjugated dienes as the oxidation product during.
Figure 3. Cholesterol profiles in macrophages incubated with oxidizedhuman LDL that have been supplemented with ginger dichloromethane extract (430 mg/ml), a-tocopherol (1 mM) or unsupplemented (control)
CONCLUSSION • Drinking ginger water extract for 30 days did not lower • blood cholesterol levels nor reduce plasma MDA • However there was significant resistance to oxidation of the • LDL against induced oxidative stress • The resistance of LDL to oxidation prevent cholesterol • accumulation in macrophage cells similar to a-tocopherol
