金一盛,鄭文植,李弘根 서울大學校 保建大學院 1973 公衆保健雜誌 Vol.10 No.1
The health of housewives those were exposed to Carbon Monoxide polluted air during use of the coal briquette, has been serious problems in the view of the public health in this country. So the investigation was attempted to find out the amount of Carbon Monoxide in kitchens of 184 houses when housewives cooked, from October 2, 1972 to October 30, 1972. The major findings obtained from this experiment were as follows; 1. The mean concentrations of Carbon Monoxide was 59ppm. 2. The Carbon Monoxide concentrations of 15 households(8.1%) exceeded 100ppm known to be the maximum permissible concentrations. 3. Mean concentrations of Carbon Monoxide were 53ppm at Korean style houses, 68ppm at Western style ones, 46ppm at apartments, and 71ppm at Korean-western mixed style houses. Carbon Monoxide in apartment did not exceeded 100ppm which was the maximum permissible concentration in the air. 4. The Carbon Monoxide concentration decreased proportionally with the decrease of kitchen space. 5. The mean of Carbon Monoxide concentrations was 93ppm until 2 hours after coal briquette changed. 6. In higher concentration of Carbon Monoxide was observed in the higher atmospheric temperature and lower pressure.

To study the effect of alginic acid on modulation of the aging process, Sprague-Dawley(SD) male rats were fed the diets containing 0, 3, 6 and $9\%$ alginic acid isolated from brown algae(Undaria pinnatifida) for 16 weeks. The effects of alginic acid on body weight, malondialdehyde(MDA) content, peroxidizability index, cholesterol and phospholipid levels, cholesterol/phospholipid(Ch/Ph) molar ratio, and fatty acid compositions in liver membranes were investigated. Increasing alginic acid level in diets did not alter food intakes but effectively decreased body weights gain(p<0.01-0.005). Malondialdehyde(MDA) contents of diets containing 6 and $9\%$ alginic acid were effectively decreased in ranges of $54.1-43.0\%$ in mitochondria, and $65.5-87.7\%$ in microsome compared with $100\%$ of control group. Cholesterol levels of all diets containing alginic acid were significantly decreased in ranges of $87.0-72.3\%$ in mitochondria, and $87.4-68.1\%$ in microsome compared with $100\%$ of control group. Phopholipid levels in microsome were significantly decreased by diets containing 3 and $ 6\%$ alginic acid but Ch/Ph molar ratios in both membranes were decreased by diets containing 3 and $6\%$ alginic acid. Increasing alginic acid level in diets significantly decreased total fatty acid but effectively increased linoleic acid in microsome except for diet containing $9\%$ alginic acid. These data on liver membranes suggest that alginic acid added to diets can modulate the physiological changes if the aging process.
