    摘要： A variety of plant diseases and damage by certain pests in agricultural and horticultural plants can be efficiently controlled without substantial chemical injuries by applying a plant-protecting composition which comprises (a) 1 part by weight of a chitosan hydrolyzate having an average molecular weight of 10,000 to 50,000, obtained by acid hydrolysis or enzymatic hydrolysis of chitosan and (b) 0.25 to 4 parts by weight of acetic acid. Any possible chemical injury to plants caused by applying the composition can be further reduced when the composition is admixed with a deproteinized juice of alfalfa leaves.

    摘要： Disclosed are a novel fructosylamine deglycase characterized by the specificity to amadori compounds of catalyzing oxidation of the compounds to produce an .alpha.-ketoaldehyde, an amine derivative and hydrogen peroxide; a method of producing the novel enzyme by cultivating microorganisms belonging to the genus Candida and having an ability of producing the novel enzyme; and a method of quantitative determination of amadori compounds by applying the novel enzyme to a sample containing amadori compounds to measure the amount of the hydrogen peroxide to be formed by the oxidation reaction or measure the amount of the oxygen to be consumed by the reaction to thereby obtain the amount of the amadori compounds from the measured value. The invention provides a novel enzyme characterized by the high specificity to the reaction with amadori compounds, especially that having therein a saccharide moiety as bonded to the .epsilon.-amino group, and also provides a method of producing the enzyme and a method of quantitative determination of amadori compounds with the enzyme. Using the enzyme, quantitative determination of amadori compounds, which is difficult by conventional enzymatic methods, is possible with ease. In particular, in measurement of the amount of a saccharified protein in a sample from a living body, which is an important index substance in diagnosis of diabetes, the enzymatic method of the invention of measuring fructosamine in the sample is hardly influenced by other interfering substances or impurities in the sample, the influence by them having been inevitable in conventional chemical methods. Accurate determination of the amount is possible by the method, and the method is free from the inconvenience of staining the kits and instruments used. For measuring glycohemoglobin, the method displays another characteristic feature that its operation is more simple and needs less labor and time than conventional methods.

    摘要： An electrophoretic medium best suited as a separation medium is composed of a gel solution and contains a water-soluble polymer and permits great improvement of the enzymic protein recovery character. A gel holder is provided with stopper members and thus can hold even a soft or slippery while maintaining a fixed shape thereof, thus permitting reliable separation and purification of an intended substance without possibility of denaturing of the substance. A slab type electrophoretic apparatus permits automatic detection of the electrophoretic state of a sample and automatic completion of the electrophoresis under optimum conditions without setting measurement condition, permits continuous measurement of the buffer solution temperature, which is important for obtaining an electrophoretic condition for maintaining the enzymic function, and permits separation and purification of a large quantity of an enzyme or like physiologically active substance in a very simple operation. An electrophoretic gel cutter cuts even large size electrophoretic gels vary accurately and safely to desired sizes and particularly cuts a soft and readily deformable electrophoretic gel of polyacrylamide or the like in a pressurized state, thus permitting accurate and safe cutting of the polyacrylamide gel, which has been very difficult to cut, without causing damage to the gel.
