The purpose of this investigation was to determine the effect of feeding trans fat on serum and tissue lipid profiles and fatty acid composition in mice. Forty-five male mice aged at 4 weeks were fed on the 10% palm oil (n-3 deficient group), 20% dried mackerel (n-3 adequate group) and 5% trans fat (trans group) for three months. Total triglyceride, cholesterol and LDL-cholesterol levels were increased in serum, liver and heart of the n-3 deficient and trans groups compared with the n-3 adequate group, while liver HDL-cholesterol levels were lowest in the trans group (p<0.05). In liver and heart, trans group showed higher levels of total cholesterol and LDL-cholesterol compared with the n-3 deficient group (p<0.05). In fatty acid compositions of serum, heart, liver and kidney, the intake of trans fat led to increased percentages of 18:1n-9trans and 18:2n-6trans. The trans group showed similar patterns to the n-3 deficient group, except an increased percentage of 18:2n-6cis. Generally, the n-3 deficient and trans groups showed increased percentages of n-6 fatty acids and decreased percentages of n-3 fatty acids, specially docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) compared to the n-3 adequate group (p<0.05). These results indicate that intake of trans fat increased total triglyceride, cholesterol and LDL-cholesterol levels, which may affect risk for cardiovascular mortality.

This study was conducted to investigate the effects of feeding probiotics on the growth performance, blood composition, and fecal noxious gas in broiler chickens. Two hundred eighty eight broiler chickens were randomly allocated into three treatments with eight replications for live weeks. Dietary treatments included 1) Control (basal diet), 2) PB 0.5 (basal diet +0.5% probiotics), 3) PBI.0 (basal diet + 1.0% Probiotics for 0 to 1 wk of age, 0.5% probiotics for 1 to 3 wk of age, 0.25% probiotics for 3 to 5 wk of age) . There were no significantly difference among treatments for the body weight gain, but the feed intake of control group significantly (p<0.05) increased as compared with the PBI.0 group in overall experimental period. Digestibility of DM in PB0.5 group (80.84%) was significantly (p<0.05) improved as compared with those in PB 1.0 (79.34%) or control group (79.15%). Although N digestibility was slightly higher in broiler chicks fed probiotics than Control, there was no significance between probiotic groups. Total cholesterol, triglyceride, HDL- and LDL-cholesterol were not significantly different among the treatments. NH$_3$-N concentration in feces with PBI .0 treatment was lower (p<0.05) than Control or PB 0.5 treatments. These results indicated that locally obtained probiotics can be effectively used for reduction of ammonia nitrogen.

This study was conducted to compare among bull, steer and heifer on growth performance, blood composition and carcass traits according to fattening phase in Hanwoo. 12 month of aged 4 bulls ($339.8{\pm}18.5kg$), 4 steers ($309.8{\pm}13.2kg$), and 3 heifers ($290.0{\pm}16.7kg$) were allocated in the stalls with individual feeding system during 20 months. Average daily gain was not different among the treatment groups during early fattening phase, but higher in the bulls and lower in the heifers after mid-fattening phase (p<0.05). The difference of body size by animal groups appeared from 24 month of age, and wither height and body length of Hanwoo heifer were the smallest (p<0.05) among treatment group. But wither height was not difference among treatment groups at 32 month of age. At 12 month of age, concentrations of serum cholesterol, triglyceride, glucose and total protein were higher in the heifers compared to other groups, and serum GPT (Glutamic pyruvic transaminase) was the highest (p<0.05) in the bulls, and serum GOT (Glutamic oxaloacetic transaminase) was the highest (p<0.05) at late fattening phase in the bulls. Meat yield index was similar between the bulls and the heifers, and the lowest (p<0.05) in the steers. Marbling score was significantly higher (p<0.05) in the steers and the heifers than in the bulls, and meat quality was the best in the steers among treatment groups. The results of this experiment might be used as a basal data on difference between gender in revision of Korean feeding standard for Hanwoo.

The purpose of this study was to analyze the effects of combined exercise on body composition and cardiovascular disease risk factors in sarcopenic obesity elderly women. The subjects for the study were 21 obesity elderly women over 65 years old. They were divided into two groups, the sarcopenic obesity group(n=9) and non-sarcopenic obesity group(n=12). The variables of body composition and CVD risk factors were measured in all the subjects before and after 16-week combined exercise. The findings of this study were as follows; In the sarcopenic obesity elderly women significantly decreased total cholesterol(TC), triglyceride(TG), and left baPWV. The non-sarcopenic obesity elderly women significantly decreased total cholesterol(TC), triglyceride(TG), low density lipoprotein-cholesterol (LDL-C), and left baPWV, but significantly increased high density lipoprotein-cholesterol(HDL-C). The most important finding in this study was that sarcopenic obesity elderly women showed delayed effects of a 16-week combined exercise on HDL, LDL-C, BP, and right baPWV compared to the non-sarcopenic obesity elderly women.

Lipids, extracted with chloroform-methanol (2:1 by vol.) and purified, from nut and leaf of Ginkgo biloba were identified and quantitatived by column, thin layer and gas liquid chromatography. The results were summarized as follow: 1) The total content of purified lipids in the nut and leaf on the fresh weight basis were 1.32% and 2.24%, respectively. 2) The lipid fractions in the nut obtained by silicic acid colum chromatography were found to be composed of about 89% neutral lipids and about 10% compound lipids, and in the leaf were found to be composed of about 28% neutral lipids and about 72% compound lipids. 3) Among the neutral lipid fractions, triglycerides (86.2%) were the major component in the nut, but esterified sterols (53.3%) were the major component in the leaf. 4) The main fatty acids of the total lipids were oleic(37.5%) and linoleic acid(44.5%) in the nut, but linolenic(45.2%) and palmitic acid (25.1%) were main fatty acids in the leaf. The patterns of fatty acid composition of the neutral lipid fractions in the nut and leaf were found to be similar, and oleic, linoleic and palmitic acid were the predominant. A large amount of oleic and linoleic acid in the glycolipid fractions was found in the nut compared with those in the leaf, but linolenic acid content in the leaf was significantly higher than in the nut. And patterns of fatty acid composition of the phospholipid fractions in the nut and leaf were found to be similar to that of glycolipid fractions.

This study was conducted to evaluate effects of dietary pine cone meal on egg production, egg quality, serum cholesterol and cholesterol content and fatty acid composition of egg yolk in laying hens. The total of 252 (51-wks) Hy-line brown commercial hens were used for 5 weeks. Dietary treatments included 1) T1 (basal diet + 1% cottonwood sawdust), 2) T2 (basal diet + 0.5% cottonwood sawdust + 0.5% pine cone meal) and 3) T3 (basal diet + 1% pine cone meal). During the overall period, there was no significant difference in egg production, egg weight and egg quality among the treatments. Lipids profile(total, HDL, LDL cholesterol and triglyceride) in serum was not affected by treatments. Egg yolk cholesterol was not significantly different among the treatments. In fatty acid contents of yolk, C18:3 was higher in T1 treatment than T3 treatment(P<0.05). Total SFA, PUFA, MUFA and UFA/SFA were not significantly different in experimental period. In conclusion, dietary supplementation of pine cone meal affected C18:3 fatty acid content of yolk in laying hens, without any adverse effect on egg production.

This experiment was designed to evaluate the effect of various dietary vitamin $B_6$ levels on conversion from linoleic acid to arachidonic acid in various tissues in growing chicks. Growing chicks were fed the purified diet containing 7% safflower oil with different levels of vitamin $B_6$ (0, 4, 8, 40, 80 mg per kg diet) for 14 days. Feed intake and weight gain in chicks fed the vitamin $B_6$-free diet were markedly depressed. Esterified and free cholesterol concentrations in serum were significantly higher, while the serum triglyceride concentration was significantly lover in chicks fed the vitamin $B_6$-free diet compared to that fed diets with vitamin $B_6$. The liver triglyceride content was also lower in chicks fed the vitamin $B_6$-free diet. The liver and serum cholesterol ester fractions in chicks fed the vitamin $B_6$-free diet showed higher rate of $C_{18:2n6}$ and lower rates of $C_{18:3n6}$, $C_{20:3n6}$ and $C_{20:4n6}$ as compared with vitamin $B_6$ fed groups. In serum phospholipid fraction of chicks fed the vitamin $B_6$-free diet, rates of $C_{20:3n6}$ and $C_{20:4n6}$ were markedly lower. As dietary vitamin $B_6$ level was increased, the rate of $C_{20:4n6}$ was slightly increased, although it was statistically not significant. The fatty acid compositions of adipose tissue showed almost the same pattern as those in liver and serum. This result suggests that the desaturation of $C_{18:2n6}$ to $C_{18:3n6}$, elongation to $C_{20:3n6}$ or both steps might be impaired by vitamin $B_6$ deficiency in growing chicks.

This study was designed to observe the effects of the feeding mixed with the sardine oil containing n-3 EPA, DHA and the safflower oil in which rich n-6 linoleic acid on the improvement of the lipids and on the fatty acid matabolism of serum lipoprotein in the dietary hyperlipidemic rats. Experimental oils mixed with 16% butter(control group) and 8% butter+8% olive oil, 8% butter and various level of sardine and safflower oils were administered to the male rats of the Sprague Dawley for 4 weeks. Concentrations of total cholesterol in serum lipoproteins were highest in the LDL, followed by VLDL, HDL and chylomicron components. in the triglyceride concentrations, chylomicron were highest, and much VLDL, LDL, HDL components. There were highest in the HDL, followed by LDL, VLDL and chylomicron in phospholipid concentrations of serum lipoproteins. Concentrations of total cholesterol, triglyceride and phospholipid in serum lipoprotein were lower in the other groups than in the control groups, and particularly, lowest in the group 5(4% sardine oil+4% safflower oil). From this results, the feeding equal quantity mixed oil with n-3 PUFA rich sardine oil and n-6 PUFA rich safflower oil were effective on the improvement of the lipid composition in the serum lipoprotein. It might be due to the effects of appropriate rations of P/S, 0.85 and n-6/n-3P, 2.85 in the test lipids. In the fatty acid composition of serum lipoprotein, ratio of P/S and n-3/n-6P were influenced from the fatty acid compositions of the mixed test lipids. And EPA contents were higher in the chylomicron components.

The lipid compositions including fatty acid sterol lipid class and the lipid component of the total lipid extracted from the flesh of some fresh water fishes I. e. mandarin cornet cat fish and Korean perch were compared. The levels of total lipid of flesh tissues from the fresh water fishes were high(7.4%) in cat fish but low(1.4-2.2%) in mandarin fish Korean perch and cornet fish. On the contrary the content of unsaponifiable matters found in total lipid was low(2.6%) in cat fish but high(6.0%-6.5%) in mandarin fish Korean perch and cornet fish. Total lipids were mainly composed of triglyceride(74.6-86.5%) as major component in each sample and the other lipid components of total lipid e. g. polar lipid free fatty acids and free sterol were the minor components, The major fatty acids in total lipid of each sample were{{{{ {C }_{16 { }:_{ }0 } }}}}(19.6-29.2%) {{{{ {C }_{16 { }:_{ }1 } }}}}(17.3-30.7%) and {{{{ {C }_{18 { }:_{ }1 } }}}}(16.8-29.2%) and additionally it chiefly consisted of {{{{ {C }_{14 { }:_{ }0 } }}}} and {{{{ {C }_{18 { }:_{ }2 } }}}} Particularly the contents of polyenoic acids in total lipid of cat fish were higher than those of the other fish samples. The level of cholesterol in total lipid was low (8.3mg/g) in cat fish but were high(36.9-59.9mg/g) in mandarin fish Korean perch and cornet fish. The contents of fractionated neutral lipid(NL) were higher than those of polar lipid(PL) in each sample. Particularly phospholipid content in PL was low(6.0%) in cat fish but were high(23.1-36.3%) in mandarin fish Korean perch and cornet fish. Neutral lipids were mainly consisted of triglyceride(84.5-93.4%) as amjor component in each sample and the other lipid components of neutral lipid e, g, free fatty acids and free wterol were exhibited as a minor components, The fatty acid compositon of neutral lipids was very resembled to total lipids. The phospholipid in mandarin cornet and cat-fish were mainly composed of phosphatidyl serine(23.1-49.8%) and phosphatidyl choline(20.8-45.3%) The relatively higher amounts of phosphatidyl serine were observed in mandarine cornet and cat-fist than in Korean perch, But phosphatidyl ethanolamine(42.3%) and phosphatidyl choline (49.9%) were the main phospholipid in Korean perch. The extraordinary high content of phos-phatidyl ethanolamine compared to other fishes was characteristics in phospholipid composition of Korean perch. The major fatty acids in phospholipid of each sample were {{{{ {C }_{16 { }:_{ }0 } }}}} (38.3-46.5%) {{{{ {C}_{18 { }:_{ }0 } }}}}(14.2-21.7) and C16:1(11.6-13.8%) and additionally it chiefly consisted of C18:2, C18:0 and C17:0 The major fatty acids in glycolipid of each sample were C16:0(28.8-40.1%) C18:1(5.4-29.9%) C18:0(5.1-28.9%) and C16:1(8.2-20.1%) and additio-nally it chiefly consisted of C14:0 and C20:1.
