Oxidative stress plays an important role in the etiology and pathogenesis of many chronic diseases. Dietary intake of antioxidants can inhibit or delay the oxidation of susceptible cellular substrates so prevent oxidative stress. The present study was designed to investigate potential protective and ameliorate effects of pineapple and kumquat powders against potassium bromate (KBrO3)-induced oxidative stress using experimental rats. Whole kumquat (seedless), kumquat seeds, pineapple flesh and pineapple leaves were analyzed for phenolic compounds. Measurement of potential of cytotoxicity against the liver carcinoma cell line (HEPG2) carried out by SRB assay of the ethanolic extract of whole kumquat seedless, kumquat seeds, whole kumquat, pineapple flesh, pineapple leaves, pineapple (flesh +leaves) and mixture of them.

The effect of different concentrations (5 and 7%) as powder of date palm pith on obese rats was evaluated. Twenty four male albino rats weighting 150 ±10 g were used in this study and divided into 4 groups, each group contained 6 rats. Rats were treated by high fat diet (20% animal fat) to induce obesity. Glucose, serum liver function (GOT GPT and ALP), lipids profile (TG, TC, LDL-c, HDL-c, VIDL-c, AI) and kidney function (uric acid, urea and creatinine)and serum protein fraction were determined. Results showed that the lower ALT, AST and ALP liver enzyme of treated group recorded for group fed on 7% date palm pith with significant differences. The lowest cholesterol and triglycerides, LDL-c and VLDL-c, uric acid, urea and creatinine values recorded for 7 % date palm pith with significant (p≤0.05) differences, while the highest (HDL-c) levels recorded for group fed on 7% mixture. As conclusion, obese rats treated with 5and 7 % powder of date palm had improved lipid profile, liver, kidney functions and glucose level. Therefore, date palm pith powder could be used in our beverages and daily level dishes, besides the fact that it has so many other health benefits.

Brown algae are a large group of multicellular algae including many seaweeds located in many countries including Egypt. Most brown algae live in marine environments, where they play an important role both as food and as habitat. The present study aims to investigate the effect of brown algae (Sargassumsubrepandum) feeding on oxidative stress (OS), antioxidant defense status and bone healthy indices in obese rats. Thirty albino male rats (140±10g per each) were divided into two main groups, the first group (Group 1, 5 rats) still fed on basal diet and the other main group (30 rats) was feed with diet-induced obesity (DIO) for 8 weeks which classified into five sub groups as follow: group (2), fed on DIO as a positive control; groups (3-6), fed on DIO containing 1, 2, 3 and 4% of brown algae powder (BAP), respectively. At the end of the experiment (8 weeks), rats of the obese group recorded 155.07% of the control (normal) group for the body weight. Replacement of corn starch with 1, 2, 3 and 4% BAP induced significant decreasing on body weight of the obese rats which recorded 137.75, 123.87, 107.69 and 94.92% as a percent of control, respectively. Biochemical analysis data indicated that obesity induced a significant increased (p≤0.05) in plasma oxidants concentration (MDA, 59.92%) and significant decreased (p≤0.05) in plasma non-enzymes antioxidant (GSH, -43.16 % and GSSG, -26.22 %), as a percent of normal group. Feeding on 1-4% of BAP induced significant exhibited a significant improvement (p≤0.05) in all of these parameters by different rates. The same behavior was recorded for the bone healthy indices. The amelioration effects were increased with the elevation of the BAP feeding rate. In conclusion,the present data support the possibility of adding brown algae powder by up to 4% to our daily diets as it contains biologically active compounds that

The present investigation aimed to assess the possibility of using flaxseeds, sesame seeds, sunflower seeds and their cakes for lowering serum glucose and hypercholesterolemia in male albino rats.Also agroup of rats received subcutaneous injection of alloxan (150 mg/kg body weights) to induce diabetes. Inflicted rats fed on seeds or seeds cake powders at 5% level for 28 days. Biological & biochemical analyses as well as the histological investigation revealed that the best treatment was that of flaxseeds cake diet 5% provided that other diets improved also diabetes mellitus but at a less extent.Since cakes revealed better results than the seeds diet it is suggested to use seeds cake after oil extraction in man's diet to control diabetes e.g. not only for animal feeds.
