    摘要: The present invention provides a charge-reversible phospholipid that is not positively charged at a pH of the body fluid (typically in the neutral range) and has low cytotoxicity.
    The present invention provides a phospholipid represented by formula (1):

    wherein m represents a natural number of 9 to 25, n represents a natural number of 10 to 15, X 1 , X 2 , and X 3 are the same or different and each represent H or OH, and R 1 represents the following formula (i) or (ii):
    wherein p represents 1 or 2, q represents 1 or 2, and r represents an integer of 1 to 4; or
    wherein s represents an integer of 1 to 3, and R 2 represents a hydrogen atom or a hydrocarbon group.

    摘要: The invention provides a method of measuring the content of polycyclic aromatic compounds (PAH) remaining in lanolin, which comprises separating and concentrating the PAH by gel permeation chromatography using a styrene-divinylbenzene copolymer and determining the concentrated PAH by HPLC with a fluorometric detector; a method of removing the remaining PAH, which comprises measuring the PAH removal activity of active carbon by the above measuring method to thereby select the optimum adsorption condition and calculate the amount of the active carbon required for lowering the PAH content, and mixing the required amount of active carbon with lanolin to thereby effect specific adsorption of the PAH onto the active carbon; and a method of removing the PAH remaining in wool grease or lanolin by the vacuum distillation of the grease or lanolin under specified conditions either directly or after being treated with a borate and, if necessary, obtaining various lanolin derivatives from the treated wool grease or lanolin.

    摘要: The present invention provides

    (1) a method for preparing lipid powder for use in the preparing liposome, which comprises supplying at a constant speed an organic solvent solution of lipids having liposome membrane forming ablility to a tubular heater heated externally, evaporating the organic solvent in the heater to prepare a mixture substantially of solids and organic solvent vapor and introducing this mixture at a high speed into a vacuum chamber of not more than 300 mm Hg, to volatilize the organic solvent instantaneously and dry the solids, and
    (2) a method for preapring liposomes comprising dispersing the lipid powder obtained by the above method (1) into an aqueous solvent.
