TL;DR: In this article, the cation-modified gum arabic is obtained by introducing a specific amount of a quaternary nitrogen-containing group to the gum-arabic and has a cation charge amount controlled within a specific range.
Abstract: PROBLEM TO BE SOLVED: To provide a compound that exhibits improved adsorbability to the hair or to the skin compared with that of conventional cationic polymers, that, when incorporated in a composition for a hair treatment, exhibits improved conditioning effects on rinsing, imparts the hair after dried with flexibility and set effects and has good hair washingoff properties resulting from good emulsifying power and that, when incorporated with a skin cosmetic composition, relieves stiff feelings and dry feelings and improves sticky feelings and slimy feelings to the skin. SOLUTION: The cation-modified gum arabic is obtained by introducing a specific amount of a quaternary nitrogen-containing group to the gum arabic and has a cation charge amount controlled within a specific range.

TL;DR: For the encapsulation of flavor compounds, maltodextrin (MD), gum arabic (GA), alkenylsuccinated modified starch (MS) and gellan gum were chosen for wall materials and their combination was optimized.
Abstract: For the encapsulation of flavor compounds, maltodextrin (MD), gum arabic (GA) alkenylsuccinated modified starch (MS) and gellan gum were chosen for wall materials and their combination was optimized. Five fruit flavor compounds having boiling point of were selected as core materials and their mixture was incorporated with rapeseed oil (flavor mixture to oil = 1 : 4). Flavor compound mixture to wall material ratio of 1 : 4 was selected, and the amount of maltodextrin was fixed to 30% of the wall material mixture. Gellan gum was selected as an additional wall material to increase emulsion stability. The optimum combination ratio of the wall material mixture for maximal total oil retention and minimal surface oil content is : 30.0% MD ; 26.4% GA ; 39.6% MS ; 4% gellan gum.

TL;DR: The results suggest that while PSP combined with acacia gum appears to exert weak immunological effects through specific T-cell dependent B-cell responses, they are likely to be broad and non-specific which supports the current literature on PSP.
Abstract: Polysaccharopeptide (PSP), from Coriolus versicolor, has been used widely as an adjuvant to chemotherapy with demonstrated anti-tumor and broad immunomodulating effects. While PSP's mechanism of action still remains unknown, its enhanced immunomodulatory potential with acacia gum is of great interest. Acacia gum, which also contains polysaccharides and glycoproteins, has been demonstrated to be immunopotentiating. To elucidate whether PSP directly activates T-cell-dependent B-cell responses in vivo, we used a well-established hapten carrier system (Nitrophenyl-chicken gamma globulin (NP-CGG)). 6-week C57BL/6 male mice were immunised with 50 μg of NP25-CGG alum precipitate intraperitoneally. Mice were gavaged daily with 50 mg/kg PSP in a vehicle containing acacia gum and sacrificed at days 0, 4, 7, 10, 14 and 21. ELISA was used to measure the total and relative hapten-specific anti-NP IgA, IgM and IgG titre levels compared to the controls. It was found that PSP, combined with acacia gum, significantly increased total IgG titre levels at day 4 (P< 0.05), decreased IgM titre levels at days 4 and 21 (P< 0.05) with no alterations observed in the IgA or IgE titre levels at any of the time points measured. Our results suggest that while PSP combined with acacia gum appears to exert weak immunological effects through specific T-cell dependent B-cell responses, they are likely to be broad and non-specific which supports the current literature on PSP. We report for the first time the application of a well-established hapten-carrier system that can be used to characterise and delineate specific T-cell dependent B-cell responses of potential immunomodulatory glycoprotein-based herbal medicines combinations in vivo.
