The acidic electrolyzed water (AEW) is known as an environmentally friendly material for the disease control in the greenhouse horticulture of strawberry. However the application technique of AEW has many cultural problems such as spraying method, spraying frequency and physiological disorder. In this experiment, therefore, we investigated the effects of slightly acidic electrolyzed water (SAEW) volatilized by using forced-air volatilizing system on gray mold disease and powdery mildew of strawberry, especially at both the stages of vegetative growth and picking period. As a result, the volatilized SAEW led the reduction of buoyant fungi in the air environment in green house. And also inhibited the symptom of gray mold disease and powdery mildew on attacked leaves and picking fruits of strawberry. On the other hand, the physiological disorder of chiorine did not occur in strawberry plant during experimental period. The volatilized SAEW retarded the lesion of fungus on fruits after picking. From the results obtained here, we should be noted that the volatized SAEW treatment is very useful for control resource or proccedure of disease injury on the strawberry plants of growing period in a green house.

Using an egg white allergen model prepared on the top plate of a stainless steel wagon, the effect of various test waters (distilled water, strongly acidic hypochlorite water, slightly acidic hypochlorite water, and strongly alkaline electrolyzed water) on removal of allergen was tested. After spreading 20 mL of each test water evenly on the egg white allergen model and standing for 3 minutes (immersion treatment), the entire amount of mixture was wiped off with a paper towel and checked for residual egg white allergen by immunochromatography. As a result, distinct allergen residues were observed in the treatment with respective distilled water and strongly alkaline electrolytic water, but in the case of each hypochlorite water, the residues were found to decrease in accordance with the effective chlorine concentration of test water. After that, it was necessary about 8 times of wiping with a cloth moistened with distilled water for the egg white allergen to become negative, whereas it took much less wiping times with hypochlorite water and strongly alkaline electrolyzed water, respectively. These results were found to be reproducible regardless of the experience and skills of the operator. These results indicate that electrolyzed water (hypochlorite water and strongly alkaline electrolyzed water) is effective in removing egg white allergens.

An approved endoscope-washing and -disinfecting apparatus using alkaline and acidic electrolyzed waters for washing and disinfection, respectively, was subjected to clinical evaluation at 3 different medical facilities in terms of its fidelity (function and disinfection effect) and practical operation convenience. The results commonly showed that varieties of bacterial species detected from clinically-used endoscopes (157 and 69 samples from upper gastrointestinal- and digestive- endoscopes, respectively) were effectively eliminated or decontaminated from the endoscopes by the automatic process of brushing with alkaline electrolyzed water washing followed by disinfection with acidic electrolyzed water. Mycobacteria, Helicobacter pylori or hepatitis virusB and C were not detected from the endoscope samples of their positive patients. Concerning the practical operation convenience, persons in charge using this apparatus appreciated the function and fidelity of the apparatus as well as the safety of the electrolyzed waters.
