This study evaluates the potential effects of pumpkin seeds protein on blood pressure (BP), plasma adiponectin, leptin levels, and oxidative stress in rats with fructose-induced metabolic syndrome. Twenty four male Wistar albino rats were divided into four groups and fed a 20% casein diet, 20% casein diet supplemented with pumpkin protein, 20% casein diet with 64% D-fructose, or 20% casein diet with pumpkin protein and 64% D-fructose for 8 weeks. Contin-uous fructose feeding induced an increase in plasma insulin/glucose ratio, BP, insulin and glucose, aspartate aminotrans-ferase, alanine aminotransferase (ALT), alkaline phosphatase (ALP), creatinine, urea, and uric acid levels, and a decrease in the liver and muscle glycogen stores.

Rats were treated for 8 weeks with diets containing 64% starch and 5% sunflower oil or containing 64% D-fructose mixed with: 5% sunflower oil; 3.4% sunflower oil and 1.

In two further groups of rats exposed to the fructose-rich diet part of the sunflower oil was substituted by either salmon oil rich in long-chain polyunsaturated ω3 fatty acids or safflower oil rich in long-chain polyunsaturated ω6 fatty acids. Despite lower food intake, the gain in body weight was higher in fructose-fed rats than in starch-fed rats.

Understanding the molecular basis of the intracellular accumulation of CDDP and other platinum-based anticancer drugs is of importance in delineating the mechanism of resistance to these clinically important therapies. Different molecular mechanisms may coexist, but defective uptake of CDDP is one of the most consistently identified characteristics of cells selected for CDDP resistance.

Spontaneously hypertensive rats (SHR; 5 wk old) were fed diets containing 20% casein or fish protein for 2 mo. Feeding the fish protein diet lowered blood pressure and reduced plasma total cholesterol levels and SOD activity in all tissues except muscle compared with the casein diet.
