Provided is a method of avoiding the influence of a coexisting substance in the measurement of HbA1c % for a whole blood sample by an enzymatic method. Specifically, provided is a method of measuring a ratio of a hemoglobin A1c concentration to a hemoglobin concentration in a sample by an enzymatic method, the method including: a first step of optically measuring the hemoglobin concentration; and a second step of optically measuring the hemoglobin A1c concentration, wherein, when HbA1c % is calculated by dividing the hemoglobin A1c concentration measured in the second step by the hemoglobin concentration measured in the first step, the hemoglobin concentration serving as a denominator, which is measured at a first wavelength, is corrected using a result measured at a second wavelength.

Method for measuring HbA1c

A method of measuring a lipid in a specific lipoprotein characterized by using a polycyclic polyoxyalkylene derivative at least in the step of determining the specificity of the measurement of the target lipid.

Method of measuring lipid in specific lipoprotein

A method for quantitatively determining LDL cholesterol, including the steps of adding to serum a surfactant selected from among polyoxyethylenealkylene phenyl ethers and polyoxyethylenealkylene tribenzylphenyl ethers and a cholesterol-assaying enzyme reagent so as to preferentially react cholestrols in high density- and very low density-cholesterols among lipoproteins, and subsequently determining the amount of cholesterol that reacts thereafter. This method can eliminate the necessity for pretreatments such as centrifugation and electrophoresis, enables the quantitative determination to be conducted in an efficient, simple manner, and can be applied to various automatic analyzers.

A rigid marine sail comprises a vertical mast secured onto a deck of a ship; at least one pivot shaft provided substantially in parallel with the mast; a left sail portion and a right sail portion pivotally secured respectively to the left side and the right side of the mast in parallel therewith through the at least one pivot shaft; and at least one drive mechanism for symmetrically pivoting the left sail portion and the right sail portion relative to the mast around the pivot shaft between a deployed position and a folded position. Each of the drive mechanisms include a set of a cylinder and a piston rod secured horizontally to the mast; a pair of L-shaped first levers, each of the first levers horizontally engaging at an end thereof with an end of the piston rod, the pair of first levers being bilaterally arranged symmetrically relative to a vertical plane which passes through the vertical axis of the mast and is parallel to the longitudinal direction of the ship, the pair of first levers being symmetrically pivotable around respective fulcrums thereof; and a pair of second levers, each of the second levers horizontally engaging at an end thereof with the other end of each of the pair of first levers, and the pair of second levers engaging at the other ends thereof respectively with the left sail portion and the right sail portion.
