This study was carried out to investigate changes in biochemical composition of rotifer, Brachionus plicatilis, enriched with the commercial enrichments (Enhance, Advantage, Algamac-2000, DHA-Selco and Advantage ＋ Chlorella) at various durations of enrichment (0, 6, 12 and 24 hr) to improve the growth and survival of marine fish larvae. Total lipid content of rotifers enriched with various enrichments tended to increase with an increase in durations of enrichment up to 6 hr, but after that, was not significantly affected by enrichment materials. However, total protein content of rotifers enriched groups except for Advantage＋Chlorella decreased with the increase in duration of enrichment. The highest protein/lipid ratio showed 2.7 in rotifer enriched with the Advantage ＋Chlorella. The phospholipid/lipid ratio of rotifer enriched with the Enhance, Advantage and Advantage＋Chlorella groups was significantly higher than that of enriched rotifer with the Algamac-2000 and DHA-Selco groups. The highest DHA level, 2.5%, of rotifer enriched for 24 hr was obtained in the Advantage, but was not significantly different among other groups, except for Algamac-2000. No significant difference in DHA level of rotifer enriched with the DHA-Selco, Algamac-2000 and Advantage＋Chlorella groups was observed between l2h and 24hr of enrichment. The DHA/EPA ratio in the enriched rotifers varied among enrichment material groups, ranged from a high level of 11.1：1 in the Advantage＋Chlorella group to a low level of 4.1：1 in DHA-Selco group. The results from this study indicate that rotifers enriched with Enhance, Advantage and Advantage＋Chlorella seemed to be effective to improve nutritional value of rotifer for marine fish larvae because phospholipid, DHAJEPA and protein/lipid ratios of rotifer enriched with Enhance, Advantage＋Chlorella were higher than those of rotifer enriched with either DHA-Selco or Algamac-2000. Especially, supplementation of the Chlorella to these enrichments would appear to be effective for improvement of fish larval performance because of no reduction of protein level in rotifer, which is critical for growth of fish larvae.

In this study, we investigated the effects of lowering the fat and cholesterol in the diets of 26 Korean hypercholesteolemic men($\geq$240mg/dl). They consumed 2378kcal/day with 20.9% of the energy deriving from fat, and a cholesterol intake of 282mg(118mg/1000kcal). The experimental diet consisted of 2400kcal, the same as their usual diet, but the fat content was restricted to 15%, and the cholesterol level to below 100mg/1000kcal. The subjects kept to this diet for four weeks and were asked to maintain their usual life activities during the experimental period. The dietary intake and levels of plasma lipid, lipoprotein-cholesterol and apoprotein of the subjects were analyzed before, two weeks into, and after four weeks dietary intervention. After two of the dietary intervention, there were no significant changes of plasma total cholesterol or triglyceride levels but there was some changes of phospholipid level. However, after four weeks, the levels of plasma total cholesterol, triglyceride, and phospholipid had decreased significantly: 18.2%, 32.9%, and 11.9%, respectively. And the LDL-cholesterol and VLDL-cholesterol levels also showed a marked reduction of 18.1%, and 33.0% respectively without change of HDL-cholesterol level. There were no changes in the levels of Apo-A 1, Apo-B, or Lp(a). The changes of the plasma lipid levels were significantly associated with the changes in dietary fat intake but not the cholesterol intake. In conclusion, although the responses to the dietary intervention varied among the individual subjects, the lowering of dietary fat component from 21% to 15% of energy intake seems to be an effective way to reduce plasma cholesterol and triglyceride levels without decreasing HDL-cholesterol level. It was also found that the restriction of dietary cholesterol to below 100mg/1000kcal not seem to be effective for the hypercholesterolemic patient who already consuming below 300mg/day of cholesterol.

These experiments were designed to study the influence of protein undernutrition during lactation period(3 wks) or after-weaning period(8 wks) on growth of organs, and on brain and liver composition of the experimental rats. The following experimental groups were studied. Group No. Rats Lactation(3 wks) (Diet of mother rat) After-weaning period(8wks) Rehabilitation Period(17wks) I 8 25% Casein diet 25% Casein diet 25% Casein diet II 8 12% Casein diet 25% Casein diet 25% Casein diet III 8 25% Casein diet 5% Casein diet 25% Casein diet IV 8 12% Casein diet 5% Casein diet 25% Casein diet After the perriod of rehabilitation(17 wks) with 25% casein diet, the following results were obtained. 1. Most of the organs except the spleen could not catch up with the normal group in their weights for the group of protein undernutrition during lactation(3 wks), even after 17 weeks of rehabilitation. For the group of protein undernutrition during after-weaning period(8 wks) brain, lung, heart, spleen and pancreas could catch up with the normal group after rehabilitation. According to this result it is assumed that the growth of brain, lung, heart and pancreas might be developed mostly during lactation and that the growth of liver and kidney might be developed after-weaning period continuously. 2. For the groups of protein underuntrition during lactation period or after-weaning period the amounts of total lipid, cholesterol and phospholipid of brain were lower than those of normal group. Especially, cholesterol level was significantly lower than normal group. And there was also a significant difference in the phospholipid level of the after-weaning(8 wks) deprivation group. 3. The groups of protein undernutrition during lactation or after-weaning period(8 wks) showed lower level of liver nitrogen and higher level of liver fat. Especially, protein undernutriton during lactation gave a greater influence on the lever of liver fat.

Purpose of this study was to compare serum phospholipid fatty acid composition of obese children with that of normal weight children reside in Kangnung area. Subjects were consisted of 56(41 boys and 15 girls) moderately or severely obese elementary school children, and age and sex-matched normal weight children as a control group. Level of serum phospholipid fatty acids was measured by thin layer chromatography(TLC) followed by gas chromatography(GLC). for male subjects, serum triglyceride(121 $\pm$ 4.7mg/dl) and total cholesterol(180 $\pm$ 37.1mg/dl) concentrations were significantly(p < 0.05) higher in obese group than those for control group(81.5 $\pm$ 2.5mg/dl and 161 $\pm$ 32.0mg/dl, respectively). Obese group showed significantly higher percentage of serum phospholipid myristic acid(C14:0) than the value for control group in both male and female subjects. Obese male subjects had significantly higher percentages of palmitoleic acid(16 : 1), oleic acid(18 : 1), dihomo-${\gamma}$-linoleic acid(20 : 3, $\omega$6) and docosatetraenoic acid(22 : 4, $\omega$6), and lower percentages of eicosenoic acid(20 : 1, $\omega$6), docosapentaenoic acid(22 : 5, $\omega$6), EPA(22 : 5, $\omega$3) and DHA (22 : 6, $\omega$3) compared to values for control male subjects. For male subjects, obese group showed significantly higher ratios of 16 : 1($\omega$9)/16 : 0 and 18 : 1($\omega$9)/18 : 0, and significantly lower ratios of 22 : 5($\omega$6)/22 4($\omega$6), and 22 : 6($\omega$3)/22 : 5($\omega$3) compacted to values for the control group. But there was not significant differences in elongation and desaturation indices of serum phospholipids fatty acid metabolism between obese and control group in female subjects. Most of anthropometric measurements related to obesity were negatively correlated with the percentages of PUFA, $\omega$3 fatty acids or DHA(22 : 6, $\omega$3), and positively correlated with the percentage of myristic acid(14 : 0) or $\omega$6/$\omega$3 ratio in serum phospholipids. Serum triglyceride concentration was negatively correlated with the percentage of PUFA or $\omega$3 fatty acids, and positively correlated with $\omega$6/$\omega$3 ratio in serum phospholipids. These results indicate that obesity related changes in blood lipid levels and metabolism are more significant in male subjects than in female subjects. Also changes in serum phospholipid fatty acid composition observed in obese children appear to demonstrate the increased susceptibility of these children to cardiovascular disease and other related chronic diseases.
