JOURNAL FREE ACCESSThe effects were investigated of orally administering carnitine and voluntary exercise on the lipid metabolism of rats fed on a high-fat diet. Male Wistar rats weighing about 250 g were divided into non-exercise and exercise groups, and each group was subdivided into carnitine-treated (100 mg/day) and non-treated groups. The exercise groups were fed in a cage provided with a wheel for exercise. All the rats were fed on a high-fat diet for 4 weeks, the exercise and carnitine treatment being given during the latter 2 weeks.
The food intake increased after the carnitine treatment. Body weight gain and the quotient of abdominal adipose tissue/body weight only decreased in the exercise group. Both in the carnitinetreated exercise and non-exercise groups, serum triglyceride, and cholesterol, triglyceride and TBA value in the liver all decreased, while β-hydroxybutyric acid in the serum increased. In the carnitine-treated exercise group, serum total cholesterol, triglyceride, TBA value and lipids in the liver all decreased, while serum β-hydroxybutyric acid increased in comparison with the non-exercise control group. These results suggest that the oral administration of carnitine during exercise improved the lipid metabolism of rats.View full abstractDownload PDF (919K) -

JOURNAL FREE ACCESSThe effects were examined of adding various nucleic acid derivatives to skim milk on the acid production of lactic acid bacteria. The bacteria used were 9 strains of Lactobacillus, 2 strains of Lactococcus, and one strain of Streptococcus.
Purine-base derivatives (50 mg each) were individually added to 100 ml of skim milk. The effects of these additions on acid production were different among the strains of lactic acid bacteria. Mainly based on the adenine effects, the strains could be classified into 4 groups as follows : growp A, stimulated by adenine and/or its related substances (2 strains of Lactobacillus); group B, stimulated by purine-base derivatives but not by adenine (3 strains of Lactobacillus); group C, inhibited by adenine and 5′-adenylic acid (4 strains of Lactobacillus); and group D, barely stimulated or inhibited by adenine and other purine-base derivatives (the 3 strains of Lactococcus and Streptococcus).
Purine-base derivatives (0.5-50 mg each) were then individually added to 100 ml of skim milk, and their effects on acid production were investigated with 3 strains of Lactobacillus, one of each belonging to groups A, B and C. The added amounts which stimulated or inhibited acid production were studied for each strain.View full abstractDownload PDF (1330K) -

JOURNAL FREE ACCESSAn attempt is made to clarify the implied meanings of “oily” and “greasy.” Twenty-eight terms were selected by researching the literature and through table discussion from many Japanese terms describing the sensation relating to oils and fats that had been collected by a free answer questionnaire. The lipid contents of foods linked with each term were calculated, and 30 panel members evaluated the relationship of these terms to such food properties as the appearance, aroma, taste, temperature and texture. The terms “oily” and “greasy” were found to be expressions used for various foods with a wide range of lipid content, and to be specifically related to several food properties such as the appearance, taste and texture, while the other terms correspond to a single food property.View full abstractDownload PDF (1279K) -

JOURNAL FREE ACCESSChanges of physical properties of nylon 6 woven fabrics dyed with disperse dye were studied for crease recovery, bending resistance (JIS), surface roughness and sensory evaluation.
As for crease recovery, untreated fabric had the highest of all, followed by blank-dyeing (control), dyed fabrics. The decrease of fabric crease recovery by dyeing and blank-dyeing was due to a decrease in the tensile recovery of the yarn.
Bending resistance and the frictional coefficient increased and surface roughness was disordered in dyed and control fabrics.
This tendency of the dyed fabric was stronger than that of the control. It was thought that the increase of bending resistance was because of the fiber compacted in the fabric structure by shrinkage of the fabrics. This phenomenon corresponds to the disorder of the surface roughness and the increase in the frictional coefficient of dyed and control fabrics.
A fairly high correspondence with the above mentioned tendency was seen in the sensory evaluation. In addition, it was found that changes in the physical properties of nylon 6 fabrics by dyeing processing were perceiveable by human touch.View full abstractDownload PDF (1189K) -

JOURNAL FREE ACCESSIn order to discuss the relationship between the heat generation by elongation and the breaking of multifilaments, the heating of nylon 66 multifilaments during drawing was measured with a thermographic apparatus. In a simple elongation, several filaments broke before allover breaking and those filament ends were thought to cause the chain breaking of neighbor filaments by collision and friction. The temperature of the filament ends was increased instantaneously because of contractions, and the generated heat conducted to the neighbor filaments. The left filaments were elongated and heated still more because of increased temperature and stress, and they broke at the peak temperature point. The temperature of the breaking point increased 29.5°C from the room temperature and the other points increased 12°C. In a loop elongation, the heat generation of the looped point was larger than others and the temperature increased 6.2°C at breaking. In a knot elongation, only the knotted point was heat generated and the temperature increased 10.5°C at breaking.View full abstractDownload PDF (1151K) -

JOURNAL FREE ACCESSThe purpose of this study was to investigate the thermophysiological effects on subjects lying on Jet Air Mattresses on summer days and sleeping on the mattresses at night. The Jet Air Mattress is used to prevent the occurrence of bedsores. Six female students volunteered as subjects for day experiments and five for night experiments. The daytime experiment involved subjects lying awake on their backs for approximately 2 h in the afternoon. The nighttime experiment encompassed 8 h of sleep. The results are as follows : 1) For the bed and clothing microclimate, the increase of absolute humidity on the back and hip was restrained with the Jet Air Mattress during both day and night experiments. 2) During the day, rectal temperatures were higher with the Jet Air Mattress than without. On the other hand, at night, rectal temperatures were lower with the Jet Air Mattress than without. 3) During both day and night experiments, hip and back skin temperatures were lower with the Jet Air Mattress. 4) The correlation coefficient between bedclimate temperature and room temperature was highly significant during night sleep (r= 0.738).View full abstractDownload PDF (1085K) -

JOURNAL FREE ACCESSThe purpose of this study is to explore the present state of usefulness of typical clothing goods and the relationship between usefulness and living factors for men's shirts. The questionnaires were sent to middle-aged housewives in their forties and fifties in the Tokyo area. Mainly the results were as follows :
1) The results revealed that men's shirts had high adaptability of cascade use compared to others.
2) The results of quantification theory II revealed the mutual relationship between the usefulness of men's shirts at home and the close connection between the family and the local region. Similar results were obtained for the use of men's shirts outside the family and school. It was determined, however, that factors influencing the usefulness of men's shirts were different between at home use and use outside the family.View full abstractDownload PDF (1521K) -

JOURNAL FREE ACCESSDespite of recent increase in employed married women, most of houseworks, childcare and eldercare are in the hands of women. The purpose of this paper is to clarify the role overload of the Japanese women in contrast to women in the Western nations by using the existing data, and to find out its causes and solutions.
In any society, women are likely to take responsibilities at home. In Japan and Korea where there is a tradition of the patriarchal stem family system, women's working pattern shows a M-shape; that is, women stay home for child rearing and start working when their children start school. Gender-segregated social structure, patriarchal stem family ideology, role expectation from others and feminine role identity are major causes for women's role overload.
To alleviate the role overload the Japanese women are now facing, an equal opportunity between men and women is not enough. Not only equality in the result and the process but also fair allocation of contraints and burdens are indispensable.View full abstractDownload PDF (1432K) -
