  • The effect of dietary fatty acid supplementation on milk production, milk composition and plasma constituents in dairy cows was examined. Dietary fatty acids including mainly palmitic acid and stearic acid were given to cows from 2 weeks before and 8 weeks after parturition. Weekly gain of daily milk production was increased gradually during early lactation period and reached a plateau at 4 weeks after parturition. Weekly gain of daily milk production in lactating cows received dietary fatty acids was significantly higher than that of cows given a control diet alone. Although milk lactose concentration was slightly decreased by dietary fatty acid supplementation, milk fat and protein were not significantly influenced by dietary fatty acid supplementation. Dietary fatty acids did not affect plasma concentrations of triglyceride, non-esterified fatty acids, total cholesterol, high-density lipoprotein cholesterol and glucose during postpartum. It is suggested that dietary fatty acid supplementation has the potency to enhance energy balance and improve milk yield without any adverse effects on milk composition.

  • The effect of slaughter weight and gender on fatty acid composition of homogenised rib samples of Hungarian Simmental (HS) and Holstein-Friesian (HF) cattle breeds was investigated. In the first experiment 22 Hungarian Simmental and 18 Holstein-Friesian cattle's meat, in the second experiment 15 females and 12 males Holstein-Friesian cattle's meat was analysed on fatty acid content. Saturated and mono- or polyunsaturated fatty acid profile did not seem to vary either by breed or by slaughter weight categories. The effect of gender, however, proved to be significant in influencing the quantity of polyunsaturated fatty acids, including linoleic and linolenic acids, as well as polyunsaturated fatty/saturated fatty acids (PUFA/SAFA) ratio. The amount of polyunsaturated fatty acids (PUFA) was higher in males than in females. Negative correlation was established between the quantity of PUFA and the amount of adipose tissue in rib samples.

  • This study was conducted to compare the lipid content and fatty acid composition of the Korean breast milk produced at 1, 2 and 3 months postpartum with the infant formula produced in Korea. The content of total lipids of the breast milk was low compared with the other data of Korean as well as foreign breast milk, and the content tended to reduce during the progress of lactation. The composition of fatty acids of the breast milk was characterized by low saturated fatty acids(SFA) and high $\omega$3 series of polyunsaturated fatty acids (PUFA), especially 20:5 and 22:6, so the P/S and $\omega$6/$\omega$3 rations were high. The formulas had more total lipids, triglycerides(TG) and phospholipids and less cholesterol(CHOL) and free fatty acids than the breast milk. The cholesterol content of the formulas was around 50% of that of the breast milk, so the CHOL/TG ratio was low. Although the formulas varied in fatty acid composition, the formulas had more SFA and $\omega$6 series of PUFA, but less monounsaturated fatty acids and $\omega$3 series of PUFA than the breast milk. This study shows that there are some differences in lipid content and fatty acid composition between breast milk and infant formula. Therefore, further studies needed to investigate the physiological effect of this difference on lipid metabolism of infants.

  • Oxidation stability and cold fuid property are considered as the most important factors for determining biodiesel quality. Among the fatty acids, monounsaturated fatty acid satisfy both oxidation stability and cold flow property of biodiesel quality standards. Microalgae with high monounsaturated fatty acid contents is have some benefit for producing to produce biodiesels with satisfying quality standards. In this study, monounsaturated fatty acid contents of a isolated microalga from Youngheung island was analyzed. Phaeodactylum tricornutum was isolated by streaking, and growth rate and fatty acid composition of the algae were investigated. Total FAME contents were consisted of 26% of saturated fatty acids, 43% of monounsaturated fatty acids, and 18% of polyunsaturated fatty acids. The contents of monounsaturated fatty acid were especially high in the Phaeodactylum species. This result implies that the FAMEs from P. tricornutum may contribute to improve the oxidation stability and cold flow property of biodiesel.

  • In order to reduce the systemic side effects and gastrointestinal irritation after its oral adminitration, ketoprofen was formulated as water-soluble packs. The effects of fatty acids and fatty alcohols on the penetration of ketoprofen through excised rat skins were evaluated. The role of stratum corneum as a protective barrier was also investigated. Fatty acids and fatty alcohols were generally effective in promoting ketoprofen penetration. The flux of ketoprofen through rat skin was maximized when oleic acid or lauryl alcohol was used as an enhancer. As the concentration of fatty acids and fatty alcohols varied from 0% to 10%, the amounts of ketoprofen penetrated were in direct proportion to that of fatty acids but those had no relationship with that of fatty alcohols. The penetration of ketoprofen through stripped skin was enhanced compared to normal skin irrespective of enhancer type, which indicated that the action site of enhancers would be stratum corneum.

  • There is increasing awareness of the devastating socio-economic cost of cardiovascular disease. As a result there have been a lot of extensive researches both on basic mechanisms involved and on the areas of epidemiology and clinical trials. Now it is being generally accepted that dietary n-3 fatty acids abundant in marine products, may reduce the incidence of cadiovascular disease. Fish oil . with its complement of n-3 fatty acids, has been shown the have diverse and sometimes potent actions on cells of the blood and vasculature, which may explain some of its positive effects on vascular disease. However, the appropriate intake of n-3 fatty acids has not been established. This may vary with desired effects, the duration of ingestion, the type of seafood or fish oil and amount of other fatty acids, especially n-6 fatty acid being consumed in the diet. Although the beneficial effects have been extensively studied, little is known about potential adverse effects with excessive intake of n-3 fatty acids. Thus, it is needed to study on the possible unfavorable effects including genetic effects.

  • A study was carried out to investigate the effect of palm oil supplementation on the growth, carcass composition and fatty acid distributions of the broilers fed isonitrogenous and isocaloric diets. This study showed that palm oil supplementation increased feed consumption, weight gain and nitrogen intake. Feed conversion improved at higher fat inclusions, but not significant. Male birds consumed significantly more feed than females resulting in significant increase in energy consumption and weight gain. Increaseing fat content in the ME:P constant diet did not produce significant difference in the fat content of the chicken. Fatty acids content of the diet exert varying effects of the composition and distribution of fatty acids in muscles of the chicken. The fatty acids found in larger amount in the breast and thigh muscles were palmitic, oleic and linoleic. The fatty acids of the breast and thigh muscles were found to correspond the fatty acids of the diets. There were no differences in the fatty acids distribution patterns between the sexes.

  • Recently it is reported that RBC membrane fluidity decreases and RBC calcium levels increase with age. The aim of this study was to analyze changes in lipid and calcium metabolism with age, and to seek relationship of diet and metabolism. With clinically normal Korean adults(male 60, female 63), this study was carried out in three phases : 1) to analyze fatty acid percentage of RBC membrane, 2) to analyze calcium levels of RBC with age, and 3) to compare the effects of dietary fatty acid intake on blood fatty acid profiles. The results are as follows : The P/S ratio of RBC membrane fatty acid decreased with age. The RBC calcium content increased according to age, with women having a higher level than men. The higher intake groups of linolenic acid(C18:3) has statistically higher serum linolenic acid levels. But dietary effects of membrane fatty acid were not found. Therefore, the further research to seek the possible relationship of diet and membrane fatty acid should be continued.

  • Objectives: The purpose of this study was to evaluate the relationship of nonalcoholic fatty liver and cardiovascular risk factors. Methods: This study was conducted to investigate the association of nonalcoholic fatty liver and cardiovascular risk factors for adult men (n=2976) and women (n=2442) who were over 19 years old, after excluding the HBsAg(+) or anti-HCV(+) patients and the men and women with increased alcohol intake (men: 40g/week, women: 20g/week). Results: Compared with the normal liver subjects, the nonalcoholic fatty liver subjects showed a significantly increased frequency of abnormal systolic blood pressure (${geq}120mmHg$), fasting blood sugar (${\geq}100mg/dL$), total cholesterol ($({\geq}200 mg/dL$), triglyceride ($({\geq}150mg/dL$), high density lipoprotein cholesterol (<40 mg/dL), low density lipoprotein cholesterol ($({\geq}130g\; m/dL$) and abdominal obesity in men, and all these measures were significantly increased in the women except for abnormal HDL cholesterol. After adjusting for the body mass index, age, smoking, exercise and a nonalcoholic liver, the odds ratios of an abnormal waist hip ratio were 1.35(95% Confidence Interval=1.05-4.72) in the mild fatty liver, 1.61 (1.19-2.18) in the moderate fatty liver, 2.77(1.57-4.92) in the severe fatty liver compared with a normal liver. The adjusted odds ratios for abnormal fasting blood sugar were 1.26(1.03-1.53) in the mild fatty liver, 1.62(1.27-2.06) in the moderate fatty Iiver and 1.77(1.12-2.78) in the severe fatty liver. The adjusted odds ratios for abnormal triglyceride were 1.38(1.11-1.72) in the mild fatty liver, 1.73(0.33-2.24) in the moderate fatty liver and 1.91 (1.17-3.10) in the severe fatty liver of men. Adjusted odds ratios for abnormal triglyceride were 1.50(1.04-2.15) in mild, 1.71(1.07-2.68) in moderate, 1.81(0.69-4.38) in severe fatty liver of women. Conclusions: The nonalcoholic fatty liver subjects had more cardiovascular risk factors compared with the normal liver subjects. Thus, prevention and treatment of the nonalcoholic fatty liver is necessary by lifestyle modifications such as restriction of alcohol intake, no smoking, exercise and adequate eating habits.
