On the basis of the results of adult disease check-up examination and nutrition survey in a region, food omposition was examined as an approach to the nutrition guidance for prevention of anemia. Besides, 22 middle-aged women diagnosed as iron-deficiency anemia were asked to take iron containing foods for 3 months to examine their benefits therefrom. In the above region, anemia (according to Hb, SI discrimination) was noted in 6.5% of women aged>30 years and in 13.2% including latent cases. Average iron intake was 8.5±2.8 mg, animal food iron intake being 1.6±0.6 mg. The anemia group showed significant low values of protein, iron and vitamin C. Iron sufficient for the nutrient requirement and animal food iron were 10 and 1.7 mg, respectively, fishery products and meats being subdivided and quantified. The above 22 women with iron-deficiency anemia were given iron containing food (iron 6 mg, vitamin C 500 mg) for 3 months. Hemoglobin level was improved to the normal 16 weeks later and could be maintained at the same level even 24 weeks later.
The purpose of this study is to make clear a comprehensive relationship between smoking and serum vitamin C in young adults. These figures are taken from 142 young healthy male. The results of the survey were as follows.1) The vitamin C in serum was 1.01±0.31 mg/dl.2) The vitamin C intake was 88.4±47.9 mg/dl.3) The mean serum vitamin C level from smokers and nonsmokers, respectively, were as follows: 1.02 (nonsmokers), 1.12 (1-10/day; smokers), 1.05 (11-20/day; smokers) and 0.87 (21 over/day; smokers). The vitamin C level of heavy smokers was lower than other group.
The effect of discontinuation of the vitamin C large loading on the blood pressure was examined. We administered vitamin C at dose of 1g/day for 24 months and then usual diet for 24 months to five subjects. The results are follows. 1) Serum vitamin C concentration was about 1.6 mg/dl in the vitamin C loading period. 2) After discontinuation of vitamin C large loading, the systolic pressure in three subjects decreased significantly (p<0.05) in the usual diet. 3) After discontinuation of vitamin C large loading, the diastolic pressure in two subjects increased significantly (p<0.05) in the usual diet.
A round trip voyage between Kagoshima and Solomon Islands via Fiji was made during a 42-day period from November 11 to December 21, 1982 including 6 days stay at Suva, Fiji and 3 days at Honiara, Solomon Islands. During this voyage, the measurements of blood pressure were taken every morning and night for each of four male adult subjects to investigate the relations between blood pressure and atmospheric temperature. The results were as follows: 1) There is no clear trend for blood pressure to increase during the voyage for all four subjects. However, the lowest value was recorded during the stay at Suva for everysubject. 2) A negative correlation between the systolic blood pressure in the morning and outside temperature was present on the return voyage to Kagoshima for subject A aged 43 years but not for two subjects; subject B aged 35 years and subject C aged 33 years. This correlation was present on the way to Solomon Islands for subject D aged 27 years. 3) A positive correlation was present between the diastolic blood pressure in the morning and outside temperature for subject B on the way to Solomon Islands and for subject B and subject C on the return to Kagoshima. For subject D, a negative correlation was present between the diastolic blood pressure in the morning and room temperature. 4) Outside temperature showed no significant correlation with the systolic blood pressure in the late evening for all four subjects during the voyage. For subject C, however, room temperature showed negative correlation with the systolic blood pressure in the late evening. 5) Significant negative correlation between the diastolic blood pressure in the late evening and room temperature were observed for two subjects; subject B and subject C. 6) In conclusion, the patterns of blood pressure variation were different among the different subjects without any consistent relation to outside temperature, suggesting the influence of mental and/or physical load during the voyage as a mediating variable in the link between blood pressure and outside temperature.
