摘要:
A plant disease control agent comprising D-tagatose as an active ingredient; and a plant disease control agent comprising at least one member selected from the group consisting of saccharides and substances each having a bactericidal and/or fungicidal activity. The plant disease control agents are effective for the control of cucumber, grape and cabbage downy mildew, damping-off in seedlings caused by Pythium spp, cucumber and barley powdery mildew, wheat stem rust, potato and tomato late blight, and others.

To provide an agricultural chemical and the like with the use of an effect of inducing systemic acquired resistance in a plant. To provide a growth inhibitor of not only a plant pathogenic bacterium but also a harmful microorganism.Utilization of a rare sugar for inducing systemic acquired resistance in a plant or inhibiting the growth of a microorganism. Utilization thereof as an agricultural chemical with the use of the effect of inducing systemic acquired resistance in a plant, a plant disease inhibitor, an inducer of a plant growth regulatory factor (i.e., an inducer of plant hormone-like actions consisting of disease resistance, insect resistance, fruit maturation, breaking of dormancy, regulation of germination, drying resistance, and other than this, resistance to environmental stresses such as low temperature resistance, high temperature resistance, salt resistance and heavy metal resistance and promotion of flowering) and a microorganism growth inhibitor. The rare sugar is an aldose (D-allose, D-altrose or L-galactose) or a ketose (D-psicose or a mixture of D-psicose and D-fructose).

摘要:
A method of utilizing the physiological activity of a rare saccharide, wherein physiological-activity sensitive cells are treated with the rare saccharide to modify the function of the cells. A composition containing, as an active ingredient, a rare saccharide which is introduced into physiological-activity sensitive cells and has an effect of modifying the function of the cells. The cells are human cells. The composition is a functional food, a drug, or a cosmetic. The rare saccharide is a rare saccharide belonging to aldose and/or ketose. The aldose is D-allose, and the cells are selected from the group consisting of cancer-cell proliferation inhibitory activity sensitive cells and active-oxygen production inhibitory activity sensitive cells. The ketose is D-psicose, and the cells are selected from the group consisting of chemokine secretion inhibitory activity sensitive cells, microglia migration inhibitory activity sensitive cells, and hypoglycemic activity sensitive cells.

摘要:
The object is to provide a novel application of D-allose (e.g., use for prevention of hypertension or hypercardia). Thus, disclosed is a composition for preventing the increase in blood pressure which comprises D-allose as an active ingredient; or a composition containing D-allose and/or a derivative thereof, preferably in an amount of 0.1 to 50% by weight. Preferably, the composition is in a form selected from the group consisting of a food additive, a food material, a beverage/food, a health beverage/food, a pharmaceutical and a feeding stuff which can be used for the prevention and treatment of a cardiovascular system disorder (e.g., hypertension, hypercardia). The increase in blood pressure may be caused by salt-sensitive hypertension. Also disclosed is use of D-allose for preventing the increase in blood pressure (excluding medical practices).
