Abstract: Porphyran with modified bioactivity and physical property, method of making the modified Porphyran and use of modified Porphyran. Porphyran with modified bioactivity and physical property is produced by dissociating a salt from a sulphate group in Poryphran and removing it, making Porphyran having a free sulphate group wherein a salt is dissociated. Further, Porphyran with modified bioactivity and physical property is produced by dissociating a salt from sulphate group in Porphyran and removing it, and then altering the sulphate group, with the use of a given salt, into a sulphate salt of the given salt. The modified Porphyran also can be obtained by converting a salt of a sulphate group in Porphyran into a sulphate salt of a given salt by ion exchange. The modified Porphyran be added to cosmetics, food, and drink, and used as cosmetic, food and drink having inhibitory activity against hyaluronidase activity.

Abstract: This invention provides a novel health food which is effective in prevention and treatment of life-style related diseases in organs in the circulatory system, such as hypertension, cerebral infarction, myocardial infarction etc. by improving blood fluidity. Phospholipid components or mineral components are collected from seaweeds of the genus Porphyra and/or seaweeds of the genus Undaria and then formed into a health food improving blood fluidity. This health food has an improving action on blood fluidity, and is thus effective in prevention and treatment of life-style related diseases in organs in the circulatory system, such as hypertension, cerebral infarction, myocardial infarction etc.

Abstract: The invention provides cosmetics obtained from naturally occurring algae as the starting material and exhibiting protective and cosmetic effects on the skin and hair. Algal proteins or their hydrolysates peptides, or derivatives thereof such as esters are contained in usual skin cosmetics, hair cosmetics, bath agents etc. The algae are preferably algae of the genus Porphyra, wakame seaweed, Chlorella or Spirulina, and preferably the proteins are extracted with a solvent directly after destroying cell walls of the algae by milling etc. The algal peptides can be obtained by treatment of the algae themselves or by enzyme decomposition, acid or alkali hydrolysis of the proteins or heating extraction under pressure.

Abstract: This invention provides a composition capable of efficiently exhibiting various kinds of physiological activities possessed potentially by seaweeds of the genus Porphyra. The laver protein-containing composition is obtained by adding water, a saline solution or an aqueous dilute alkali solution to seaweeds of the genus Porphyra or finely divided dry particles thereof, wet milling the materials to extract soluble components therefrom, and separating proteins form the extract. A composition containing different kinds of laver proteins may be obtained by separately conducting extraction with water, a saline solution or an aqueous dilute alkali solution, or a composition containing a mixture of laver proteins may be obtained by conducting such extraction procedures successively.

Abstract: A rotary light coupler comprises a first light emitter and a first light receiver mounted on a fixed body, and a second light emitter and a second light receiver mounted on a rotary body. The first and the second light emitters are arranged to transmit light beams containing signals to the second and the first light receivers respectively, through a rotary mechanism.
