Introduction

Article Abstract:

The characterization of phytochemicals often define the creation and construction of so-called nutraceuticals and designer foods. These phytochemicals, which are the active ingredients of plant foods known to have beneficial effects on people, are now the subject of much research. Several phytochemical classes are examined in the papers submitted to the symposium. Among others, the papers examine the possible therapeutic uses of polyphenolics, phytoestrogens, monoterpenes and isothiocyanates.

Lung eicosanoid synthesis is affected by age, dietary fat and vitamin E

Article Abstract:

A study was done on the effect of age, dietary fat and vitamin E on eicosanoid synthesis in the lungs. Results show that age affects ex vivo synthesis of eicosanoid which constibute to the pathological changes observed in the lungs with advancing age. Furthermore, it was shown that vitamin E supplementation increased 6-keto-prostaglandin F1alpha (PGI2) levels while increase or decrease in thromboxane B2 and PGI2 was dependent on the type of fat given in the diet.

(n-3) fatty acids, tissue lipid peroxidation and tocopherol status

Article Abstract:

A study on the effect of (n-3) fatty acids on lipid peroxidation and activity of enzymes involved in oxidative stress protection in rats failed to include changes in tocopherol status which is the main antioxidant involved in the process. In addition, gender differences in lipid peroxidation was not explained. It was pointed out that this observation may be a result of the differences in incorporation of fatty acids between male and female rats.
