To provide a means capable of suppressing deterioration in the soundproofing performance of a soundproofing material capable of exhibiting high soundproofing performance over a wide range of a frequency range of 2000 Hz or less. A soundproofing material including a sheet having elasticity, and a support portion partitioning the sheet into a partition portion while supporting the sheet is configured so that a surface rigidity (k) of the sheet and a surface density (m) of the sheet in the partition portion satisfy a relationship of the following Expression 1. Further, the soundproofing material is disposed on a substrate so that the sheet is separated from the substrate to configure a soundproofing structure:

Soundproofing structure

To provide a means capable of suppressing deterioration in the soundproofing performance of a soundproofing material capable of exhibiting high soundproofing performance over a wide range of a frequency range of 2000 Hz or less. A soundproofing material including a sheet having elasticity, and a support portion partitioning the sheet into a partition portion while supporting the sheet is configured so that a surface rigidity (k) of the sheet and a surface density (m) of the sheet in the partition portion satisfy a relationship of the following Expression 1. Further, the soundproofing material is disposed on a substrate and a vibration separation layer is further disposed between the soundproofing material and the substrate to configure a soundproofing structure:

To provide a means capable of exhibiting high soundproofing performance over a wide range of a frequency range of 2000 Hz or less. A soundproofing material includes a sheet having elasticity and a support portion partitioning the sheet into partition portions while holding the sheet, in which a surface rigidity (k) and a surface density (m) of the sheet in the partition portion are configured to satisfy a relationship of the following Expression 1.

It is intended to find novel pharmaceutical use of sphingomyelin and to provide preventive or therapeutic agents for various diseases as well as a food and drink product and feed comprising any of these agents. The present invention provides a pharmaceutical agent which contains sphingomyelin as an active ingredient and is any of the following agents: 1) a sialomucin secretion promoter, 2) an agent for preventing drunken sickness (hangover), 3) an antiallergic agent, 4) an antioxidant, 5) an agent for defending against infection, 6) a hair growth agent, 7) a therapeutic agent for demyelinating disease, 8) an anti-pigmentation agent, 9) an anti-inflammatory agent, and 10) an agent for improving learning ability. The present invention also provides a food and drink product or feed, characterized by comprising the agent. It is preferred that the sphingomyelin should be derived from milk.

Medicine, food and drink or feed containing sphingomyelin

A skin beautifier contains sphingomyelin, which is a phospholipid, as an effective ingredient. In addition, skin-beautifying food or feed contains sphingomyelin as an effective ingredient. The present invention provides a skin beautifier and skin-beautifying food or feed supplying effects on beauty, such as skin-moisturizing and protecting effects, skin-roughness-preventing and improving effects, and a wrinkle-preventing effect, by oral ingestion thereof.

Skin beautifier

A composition with a high ganglioside content is manufactured by a method characterized in that milk or milk-derived material containing ganglioside is dispersed in an ethanol solution so that the concentration of ethanol becomes 60&tilde;95%; after removing the precipitate which is generated by heating the solution to a temperature higher than 50&deg; C., the obtained supernatant is cooled to a temperature lower than 0&deg; C; and the obtained precipitate is recovered. The obtained composition with a high ganglioside content is used advantageously as a material for foods and drinks, medicines, chemical products, etc.

Method of manufacturing compositions with high ganglioside content

A method of preparing Ganglioside G.sub.M3 which comprises thermally treating a lipid containing material which includes Ganglioside G.sub.D3 at a temperature of from 60.degree. to 140.degree. C., for a period of from 2 to 180 minutes at a pH ranging from 6-8. The lipid containing material contains at least 10 wt % liquid and is cream or a milk product prepared from cream.
