The aim of the present study was to evaluate some potential therapeutic effects of peel and pulp of two eggplant varieties (round black and long white) which are widely consumed among Egyptian people using experimental rats. Peel and pulp samples were analyzed to determine the chemical composition and some minerals (Na, K and Fe). Total phenols content also were determined in addition to the identification of phenolic compounds by HPLC. The dried peel and pulp of two eggplant varieties were supplemented as 15% to the diet and used for treating diabetic, hypertensive, and hyperlipidemic rat. Thirty male albino rats weighing 140±10 g were divided to 6 groups (5 rats in each group). Five groups were given 10% fructose in the drinking water for 6 weeks to induce hypertension, hyperlipidemia and hyperinsulinemia. At the end of the experiment, Serum glucose, insulin, total cholesterol, triglycerides, lipoprotein fractions, blood pressure, serum Na, K, and MDA levels were determined in rats serum. In addition the kidney and liver of rats were removed after ether anaesthetesia and making histopathological examination. Briefly, different tested eggplant types can be considered as a good healthy food which can prevent and improve the status of hyperglycemia, hyperlipidemia, and hypertension. Peel of round black eggplant was more effective for lowering hyperlipidemia and hypertension and improved lipid profile, while the long white type was more effective for lowering hyperglycemia. These healthy effects of eggplant can be attributed to its good content of fibers, phenolic compounds, and potassium. Furthermore, the eggplant has the ability to bind with bile acids and inhibiting the activity of some enzymes as αglucosidase and angiotensin converting the enzyme which increases hypertension.
his study was conducted to investigate the effect of college hostels residents' life style and eating habits and their impact on liver, kidneys and gastro intestinal system (GIT), and to compare between girls and boys inside the hostels concerning the same parameters. The study started by giving several questionnaires to elicit their general complaints and detailed symptoms, after which anthropometric measures were taken then clinical examinations and laboratory investigations were carried out. The study tried to detect the most prevailing GIT, liver and kidneys diseases that affected students in university hostels. Recommendations to solve these complaints were presented. The study found that college students in the university hostels practiced unhealthy life style and food habits; 53% ate while watching TV, 8% of boys are cigarette smokers, the frequency of sports per week was as low as 1.2 times only, 70% of students preferred junk foods and 45% of students preferred fried foods. These habits affected the GIT negatively as the most prevalent general complaint was pain, food allergies and infestations. 81.7% of all students had troubles of GIT, 83.4 % of girls and 80% of boys. Students were then clinically examined and samples were drawn for laboratory tests. Clinical examination showed prevalence of GIT signs (72%).
