This study was conducted to investigate the effect of Zn and Fe levels on lipid metabolism and micromineral contents in high fat diet-induced obese rats. Male sprague-dawley rats weighing approximately 100g were fed a normal or high fat diet. After 10 weeks high fat diet, rats were fed different levels of Zn and Fe. Serum triacyglycerol and HDL-cholesterol were affected to Zn and Fe levels in normal group. The micromineral (Zn, Fe, Cu, Mn) contents in liver were significantly different in high fat diet group by Zn intake levels and in normal diet group by Fe intake levels. However, micromineral contents in kidneys were not affected to different levels of Fe in both obese and normal rats. There were no differences in spleens of obese rats fed high fat diet according to Zn and Fe intake levels. But in normal group, Mn content of spleen were exclusively affected to Zn levels.

Vitamin and mineral composition of ethephon treated tomatoes were studied, and the results are summarized as follow: 1. Ascorbic acid, carotene (total and beta-carotene), thiamin and riboflavin contents in tomato fruits were not adversely affected by ethephon treatment 1 week before harvest, and these results were consistent for two consecutive years. Riboflavin content of tomatoes in 1979 was significantly higher than that in 1978, and this difference could be due to enviornmental factors. 2. Mineral content in tomato fruits were not significantly affected by ethephon treatment 1 week before harvest. Calcium and manganese contents in treated tomatoes significantly varied from year to year.

This paper summarizes the processing inorganic continuous fibers from Korean minerals. Continuous filament fibers have been produced from two rocks, basalt and quartz diorite porphyry(QDP), by melting method. The essence of the method is that the vitrified materials was placed into the bushing, platinum/rhodium alloy crucible with a nozzle, and heated electrically to a temperature which allowed fiber spinning. Vitrified basalt without additive was suitable for producing continuous filament fiber. However doping quartz diorite porphyry with boric oxide yielded a material which could be pulled continuously.
