    摘要: Aqueous blood-sample diluting reagent and method of its use for compelling a morphological change in a blood sample to yield an MCV value assayed at elapsed time after the sample is drawn to be consistent within a diagnostically acceptable range with the original, immediate post-drawing MCV value. Selection of a small amount of a predetermined surfactant added within a limited range of concentration, and of a salt for adjusting osmotic pressure of the sample is thereby determined. The blood sample is treated with an anti-coagulant agent immediately post-drawing, and for assay in a particle analyzer at post-drawing elapsed time is diluted with the reagent solution. The reagent has an osmotic pressure (&pgr;) of approximately 150-400 mOsm/kg and a pH of 6.0-8.5. The surfactant is present in a 0.0005% to 0.5% concentration and has a hydrophile-lipophile balance (HLB) of 10-20.

    摘要: A system for making an optimum plan for a given problem at high speed. The system sets a planning problem, etc., prepares an objective function and finalizes a plan for minimizing or maximizing the objective function value, and then stores necessary variables. The system prepares as many parent plans of a first generation as a given number (population), calculates objective function values, sorts plans in descending or ascending order of the objective function values of the plans, when selection numbers are assigned to plans in order of a ratio of the objective function value of each plan to the total of the objective function values of the plans, selects parent plans by using numbers indicated by as many constants as the population determined for each generation as the selection numbers, and replaces two elements, arranged at order positions specified by random numbers, with each other for each of the selected parent plans, to prepare child plans.

    摘要: Reagents for enabling leukocytes to be classified and counted lyse erythrocytes and act on leukocytes to stabilize them are disclosed. The reagents contain polyoxyethylene-based surfactants, and may contain hyperosmotic or hypoosmotic agents and solubilizing agents. One embodiment of the invention contains surfactants selected from the anionic and nonionic polyoxyethylene-based surfactants having 18-30 repeating oxyethylene units per molecule. A second embodiment of the invention contains nonionic polyoxyethylene surfactants only, having 20-100 repeating oxyethylene units per molecule, does not employ either saponin or quaternary ammonium compounds, and provides for adjustment of the pH of the resulting solutions. The invention allows leukocytes to be classified into as many as five types, each type to be quantified, and enables the detection of abnormal cells, when used in conjunction with particulate analysis flow cytometers employing the RF method and the DC method.

    摘要: A reagent for and method of measuring leukocytes or hemoglobin or both in blood using a reagent which is water-soluble mixture containing:(a) a polyoxyethylene-based nonionic surfactant represented by the formula:R.sub.1 --R.sub.2 (CH.sub.2 CH.sub.2 O).sub.n --H where R.sub.1 is an alkyl, alkenyl or alkynyl group having 6 to 24 carbon atoms, R.sub.2 is --O--, ##STR1## or --COO--, and n is an integer of 6 to 50, and (b) a buffer to adjust the pH of the solution within the range of 3-11 is disclosed. Measurements of hemoglobin in blood samples are of extreme importance to clinical diagnosis of such diseases as leukemia and anemia. Measurements of eosinophils, which are in the category of leukocytes, are important to the diagnosis of allergic conditions.
