Abstract
Cholesterol is actually a good thing. This fatty, waxy substance is used by the body to build cell membranes, insulate nerve fibers and create hormones. It’s absolutely vital to life. The problems begin when there is too much of certain kinds of cholesterol specifically, total cholesterol and LDL, and too little of a third kind, HDL. Too much of the former can result in clogged arteries that can lead to a heart attack or stroke and too little of the latter can cause the same results, since HDL actually carries excess cholesterol out of the body. (Taylor, 2008) Researchers believe that green tea lowers blood cholesterol by reducing its absorption in the digestive tract, while increasing its rate of excretion and fight the conversion of LDL to its more dangerous, oxidized form (Frick, 2007). Drinking 2 cups only per day can lower LDL cholesterol levels by as much as 13 mg. Green tea may also help keep cholesterol levels down even when the diet is high in fat. Studies founded that those receiving green tea catechins had lower cholesterol levels and other indicators of heart disease risk than those that didn’t receive it. (Canner, 2006). The current study was carried out to determine the impact of using conventional therapy versus green tea on blood cholesterol levels for patients with hypercholesterolemia. The current study was conducted at the clinics of medical department of Menoufyia University Hospital, Egypt. Data collection for this study was extended from the first of June 2006 to the middle of March 2007. The sample of this study consisted of 60 adult patients recently diagnosed with hypercholesterolemia was divided into two equal groups; 30 patients for each group; The study group (I) was received green tea (herbal therapy) beside the prescribed hypocholesterolemic drugs, diet, exercise regimen and healthful pattern of life style while the control group (II) was received conventional therapy only (the hypocholesterolemic drugs, diet, exercise regimen and follow pattern of healthful life style). Patients of both groups were selected according to the following criteria: 1. Adult with a diagnosis of first level hypercholesterolemia. 2. Both sexes. 3. Total cholesterol will range from (200-240 mg/dL) and HDL less than 40 mg/dL. 4. Free from any other associated disorders such as diabetes mellitus. 5. None smokers. 6. On lipitor drug (2 tablets daily for a period of three months). Research hypothesis Patients in the study group (green tea) is expected to have cholesterol reduction more than in the control group (conventional) who did not use the green tea. : of the studyTools To achieve the aim of the study, the investigator used three tools based on review of the related literature to collect the necessary data The following tools were used: Tool I: Knowledge Assessment Sheet Tool II: Nutritional Assessment Sheet Tool III: An Evaluation Sheet Tool I: knowledge assessment sheet: structured interview questionnaire (Appendix II): This tool was developed by the researcher after reviewing the related literature to assess the patients’ knowledge about hypercholesterolemia and their awareness of therapeutic regimen, it was in Arabic and it was included three parts: a) Part one: Sociodemographic data b) Part two: Health History c) Part three: patient’s knowledge Tool II: Nutritional Assessment Sheet: Appendix III This tool was designed by the researcher based on the review of related literature to identify the patients’ nutritional pattern based on the nutritional indicators and it was included four parts: a) Part one: Three Days Dietary Recall b) Part two: Anthropometric measurements c) Part three: Lab findings Tool III: Evaluation Sheet: Appendix IV This tool was developed by the researcher after reviewing the related literatures to identify the effect of conventional therapy (green tea) on cholesterol level. It was included the following parts: a) Part one: Lipid Profile b) Part two: Diet c) Part three: Exercises d) Part four: The Prescribed Therapy e) Part five: The Pattern of Lifestyle f) Part six: Lab Investigations g) Part seven: visual analogue pain scale h)
