ジャーナル フリーThe relationship between dirt and fungal contamination in bathrooms and the effect of cleaning were examined. Levels of dirt were higher on the floor than on the wall, although the number of fungi was smaller. Factors other than fungal contamination, including bacteria and dust, may play an important role in the development of floor dirt. Exophiala in particular, more than Cladosporium, Rhodotorula, and other species, seemed to affect dirt levels on both floor and wall.
Cleaning to eliminate fungi was divided into physical and chemical treatments. Fungal colonies growing on bathroom surfaces are difficult to wipe off, and about half of the dirt could not be eliminated without abrasion, regardless of the kind of fungus.
Exophiala and Cladosporium grew faster than other fungi but were eliminated effectively by cleaning with hypochlorite, which was however less effective against Phoma and Scolecobasidium. Elimination of fungi at about one-month intervals is needed to control fungal contamination as bathroom fungi grow at a rapid rate in the month after elimination.抄録全体を表示PDF形式でダウンロード (328K)

ジャーナル フリーIn the area of general foods, phytosterols are mainly present in vegetable oils, but it is not known to what degree these oils can contribute to the reduction of plasma cholesterol because the amount used in cooking is limited. In the present study, to investigate the contribution of vegetable oils to dietary phytosterol content, take-out lunches were selected as model meals and divided into three groups based on the amount of vegetable oils in the main dish: a deep-fried dish group, a stir-fried dish group and a boiled or baked dish group. Even in the deep-fried group, which had the highest vegetable oil content, average phytosterol content was 49.2 mg/diet, which was much smaller than the value calculated by adding together the individual values for phytosterol contained in foodstuffs consumed daily. The boiled or baked dish group, meanwhile, which had the lowest phytosterol content, contained 33.5 mg/diet, which seemed to originate mainly in the vegetables and cereals themselves. The cholesterol content and cholesterol/phytosterol ratio were similar in the three groups and there was no significant correlation between cholesterol and phytosterol content in any of the groups.抄録全体を表示PDF形式でダウンロード (396K)

ジャーナル フリーOsaka City has addressed the resolution of solid waste problems from the middle of Meiji era, and conducted full-scale research on disposal in the middle of Taisho era. It was the first time that City analyzed solid waste in detail within the research. City also analyzed solid waste in Showa era for the study of disposal method. In this study, experimental separate collection was implemented and separated solid wastes were analyzed. The Osaka Municipal Hygienic Laboratory took charge of analysis in those researches, and also analyzed solid waste independently. After the World War II, when City introduced continuous incineration plant from Europe, the Laboratory compared the conventional method of solid waste analysis with the method introduced from Europe, and found that there was little difference between two methods, and have established the analytical method that has been used until now. In the material, the results of solid waste analysis conducted in those studies are shown.抄録全体を表示PDF形式でダウンロード (1525K)
