, (2007/10/06)
PROBLEM TO BE SOLVED: To provide a composition for ameliorating allergic constitution naturally ingestible in daily life. SOLUTION: The composition for ameliorating the allergic constitution comprises a galactooligosaccharide as a main ingredient. Furthermore, a food and drink uses the composition. Since the galactooligosaccharide is already widely used in heath-oriented foods such as a specific food for health and is a material in which the safety is sufficiently established, the galactooligosaccharide is naturally ingestible over a long period in the daily life.

Synergistically acting compositions for selectively combating tumor tissue
-
, (2008/06/13)
According to the invention, compositions are made available which have a strong cytotoxic effect which is largely selective on tumor tissue. The invention is based on the fact that certain benzoic acid derivatives have a strong synergistic effect as a mixture and destroy cancer cells selectively in a pH range of 7 or below, such as from 6.5 to 7.

The reaction of aldehydes with acetic anhydride in the presence of catalytic cobalt(II) chloride under an oxygen atmosphere at ambient temperature is dependent upon the reaction medium.Aliphatic aldehydes react in acetonitrile to give 1,2-diones whereas the aromatic aldehydes are acylated to yield the corresponding acylals.On the other hand, carboxylic acids are obtained from aliphatic and aromatic aldehydes by conducting the reaction in dichloroethane or benzene.Cobalt(II) chloride in acetonitrile catalyzes the conversion of aliphatic aldehydes to the correspondinganhydrides in the absence of acetic anhydride whereas aromatic aldehydes remain largely unaffected under these conditions.A preliminary mechanistic study in three different solvents (i.e. acetonitrile, dichloroethane, and DMF) has revealed that in acetonitrile and in the presence of acetic anhydride, aliphatic aldehydes behave differently than aromatic aldehydes.Some trapping experiments using methyl acrylate and stilbene have been conducted to demonstrate the occurence of an acyl cobalt and peroxyacyl cobalt intermediate during these reactions.
