A method for the treatment of a person suffering from neurodegenerative disease such as Alzheimer's, Parkinson's, or Huntington's disease by treating the patient's brain, over the span of one year or less with a plurality of doses of ionizing radiation, each dose being more than 2.5 mJ/kg but less than 150 mJ/kg with the total dose being more than 10 mJ/kg but less than 400 mJ/kg.

The instant invention is the storage of Type II collagen containing tissue in carbonated water. Such Type II collagen is useful for alleviating the symptoms of arthritis in mammals as well as the treatment of arthritis in mammals. Such Type II collagen is also useful for the prevention of arthritis in mammals. The instant invention is also a method for the preparation of a nutritional supplement that includes the steps of: (a) separating water-insoluble undenatured Type II collagen containing animal tissue from animal tissue not containing Type II collagen; (b) subdividing and sterilizing said tissue under conditions which do not change the original structure of the Type II collagen to produce a subdivided and sterilized product; (c) packaging the subdivided and sterilized product in carbonated water.
摘要:
A method for adding intact fiber reinforcing material into thermoplastic resin compositions for toughening purposes without breakage of the fibers, including blending a polymeric solution and chopped fibers in a mixture at low to medium shear, injecting the resulting mixture into an extruder with a resin to be reinforced at an entry point positioned very near a vacuum point, and then removing the solvent for recycle while the reinforcing glass fiber and polymer blend is extruded.
摘要:
This invention relates to an improved method for forming a grafted rubbery particle suitable for use as a reinforcing rubber in a thermoplastic resin. The grafted rubbery particles produced by the method of the present invention have a substantially continuous, generally uniform layer of polymer grafted to the rubber particle core.
摘要:
Alkali metal salicylate can be efficiently acidified and the salicylic acid product formed contemporaneously sublimed by contacting the salicylate as a solid with gaseous hydrogen chloride at the conditions specified. The temperature of the gaseous hydrogen chloride is controlled so that the heat required to sublime the salicylic acid product is predominantly supplied by the heat of reaction of the hydrogen chloride with the alkali metal salt of the carboxylic acid.
摘要:
The instant invention is a method for freezing chicken cartilage containing undenatured Type II collagen so that more than eighty percent the Type II collagen of the frozen chicken cartilage remains in the undenatured state. The method is to expose chicken cartilage to a gas such as carbon dioxide gas at a temperature between minus 0.65° C. and minus 1° C. to freeze the chicken cartilage so that more than eighty percent the Type II collagen of the frozen chicken cartilage remains in the undenatured state. In another embodiment, the instant invention is method for freezing chicken cartilage containing undenatured Type II collagen by freezing the chicken cartilage in a thermally insulated container such as a container formed of foamed polystyrene.
摘要:
This invention provides a method of preparing animal tissue containing water-insoluble undenatured Type II collagen for use in treating autoimmune arthritis, particularly rheumatoid arthritis.
摘要:
This invention is a method and an apparatus for rapidly devolatilizing a product of a polymerization process containing at least one volatile material. The product is initially devolatilized in a high temperature zone, and the foamed devolatilized product is separated into a gas and a liquid polymer phase and rapidly removed therefrom to minimize depolymerization and degradation of the polymer. The partially devolatilized product is further devolatilized by feeding it into a rotatable chamber which is rotated at a sufficient angular velocity to create a high gravitational field to form a vapor and a polymer liquid pool.
摘要:
A particulated thermoplastic polymer having a uniform surface coating of zinc stearate is prepared by contacting the polymer particles with atomized droplets of molten zinc stearate while supporting and conveying the polymer by a moving stream of a gas. Reduced frictional forces allow increased volumes of coated particles to be transported by pneumatic conveyance. Substantially reduced fine particulate generation or "dusting" is observed for the composition.
