摘要:
Lipid is determined quantitatively by treating a sample with a surfactant in an aqueous medium to obtain a liquid sample dispersion, then reacting the dispersion with a reagent containing cupric ion and bicinchoninic acid, and measuring a colored state developed by complex formation of bicinchoninic acid with cuprous ion formed from cupric ion in the presence of lipid. This method can be effectively applied to determination of amphiphilic lipid having a tendency of gathering in an aqueous medium. Further, two different species interfering with each other in quantitative determination thereof are determined respectively by conducting two different determination methods on the same sample followed by calculation using the values obtained.

The invention provides a particulate construct such as microcapsules containing a drug, and serving a slow releasing preparation not associated with a practically unacceptable initial burst release but showing a practically acceptable zero-order release for a certain period and a producing method for such particulate construct, and a slow releasing preparation of a high drug content capable of stably incorporating the drug in the particulate construct such as microcapsules, and a producing method for such preparation. The invention also provides a particulate construct such as microcapsules utilizing a highly functional polymer compound and incorporating oil phase and/or water phase in solid phase, and a producing method therefor. Furthermore, the invention provides a particulate construct such as microcapsules having a hollow structure of a single polymer membrane as the outer shell and capable of containing many bubbles in the fine particles, and a producing method capable of preparing such construct with a high reproducibility. According to the invention, a particulate construct such as microcapsules is formed with polyhydroxyalkanoate of a specified structure and a drug for a desired purpose, an oil phase and/or a water phase, or a gaseous phase is included in such construct.
摘要:
The invention provides coloring composition for color filters making use of a pigment, in which the dispersed state of the pigment is stable without using any surfactant, and so aggregation is hard to occur, and which permits formation of high-definition and high-quality images excellent in color rendition, transparency and contrast, and a simple production process thereof, by which the use of surfactants can be abolished, or the amount of surfactants used can be reduced to a great extent. The coloring composition for color filters is provided by using at least a coloring material obtained by coating at least part of surfaces of pigment particles with polyhydroxyalkanoate, and a dispersion medium for the coloring material.
