Analysis of the natural abundance C content of dibutyl phthalate (DBP) from two edible brown algae, Undaria pinnatifida and Laminaria japonica, and a green alga, Ulva sp., revealed that the DBP was naturally produced. The natural abundance C content of di-(2-ethylhexyl) phthalate (DEHP) obtained from the same algae was about 50-80% of the standard sample and the C content of the petrochemical (...

Laminaria japonica Areshoung, a widely consumed marine vegetable, has traditionally been used in Korean maternal health. The present study investigated the antiobesity effects of Laminaria japonica Areshoung ethanol extract (LE) and its molecular mechanism in high-fat-diet-induced obese rats. Six-week-old Sprague-Dawley male rats were separately fed a normal diet or a high-calorie high-fat diet...

The experiment was conducted to investigate the effects of dietary vitamin K on survival, growth and tissue vitamin K concentrations of abalone, Haliotis discus hannai. Eight purified diets were formulated to provide a series of graded levels of menadione sodium bisulfite (MSB) (0-320 mgkg(-1) diet). The brown alga, Laminaria japonica, was used as a control diet. Abalone juveniles of similar si...

Spores and gametophytes are considered to be those life-history stages of kelps most susceptible to environmental perturbations and, in particular, to temperature and UV radiation. Microstages of Arctic (Saccharina latissima, Laminaria digitata, Alaria esculenta from Spitsbergen) and temperate kelp species (S. latissima, L. digitata, L. hyperborea from the North Sea) were exposed in 2-factorial...

To test the potential in vivo antitumor effect of dietary sea weed, we induced mammary tumors in female Sprague-Dawley rats with the carcinogen 7,12-dimethylbenz(a)anthracene. Twenty-one-day-old rats (n = 108) were divided into two groups. Controls were fed a standard semipurified diet, and experimental rats received the control diet with 5% Laminaria, a brown sea weed, replacing 5% alphacel. A...

The conductance of Laminaria, Saccharomyces, Bacillus coli and Bacillus butyricus, Chlorella, and of red blood cells has been studied by the writer's method, and Laminaria by that of Osterhout. For the material studied it has been found that: 1. The conductance of living tissue is closely proportionate to, and determined by that of the surrounding fluid with which it is apparently in equilibriu...

The influence of oscillatory versus unidirectional flow on the growth and nitrate-uptake rates of juvenile kelp, Laminaria digitata, was determined seasonally in experimental treatments that simulated as closely as possible natural environmental conditions. In winter, regardless of flow condition (oscillatory and unidirectional) or water velocity, no influence of water motion was observed on th...
