Elevated serum concentration of inflammation markers is known as an independent risk factor of metabolic syndrome (MS) and dietary intake is an important factor to control MS. The purpose of this study was to investigated the hypothesis that inflammatory indices are associated with dietary intake and diet quality index-international (DQI-I) in subjects with MS. A cross-sectional study was conducted on 156 men and 73 postmenopausal women with MS, defined by three or more risk factors of the modified Adult Treatment Panel III criteria. Serum levels of high sensitive C-reactive protein (hs-CRP), adiponectin were examined and nutrients intake and DQI-I were assessed using a semiquantitative food frequency questionnaire. The total DQI-I score was significantly higher in female subjects ($65.87{\pm}9.86$) than in male subjects ($62.60{\pm}8.95$). There was a positive association between hs-CRP and polyunsaturated fatty acid intake (p < 0.05) and a negative association between adiponectin and lipid (p < 0.05), total sugar (p < 0.01), and total fatty acids (p < 0.05). When the subjects were divided into 5 groups by quintile according to serum adiponectin and hs-CRP level, there was no association between DQI-I score and hs-CRP levels. Moderation score of DQI-I was significantly higher in highest quintile group than the lower quintile groups. Therefore, our results provide some evidence that dietary intake and diet quality are associated with inflammation markers and dietary modification might be a predictor to decrease risk for metabolic syndrome complications. However further research is needed to develop the dietary quality index reflecting the inflammatory change by considering the dietary habit and pattern of Koreans.

The concentration of cordycepin produced by crossbred Cordyceps militaris JLM 0636 (CM${\alpha}$) was 7.42 mg/g dry weight, which was 7-fold higher than that of C. militaris (CM). However, cordycepin was not detected in Paecilomyces japonica (PJ). The improvement effects of CM${\alpha}$, CM and PJ on orotic acid (OA)-induced fatty liver in male Sprague-Dawley rats was investigated. Rats were randomly divided into five groups (n=6) based on five dietary categories: normal (N), OA control (C), OA plus 3% (w/w) PJ (PJ), OA plus 3% CM (CM), and OA plus 3% CM${\alpha}$ (CM${\alpha}$). OA treatment induced the retardation of body weight gain and enlargement of the liver. The concentration of hepatic triglyceride was markedly increased by OA-feeding, whereas this rise was significantly reduced by simultaneous feeding of OA, PJ, CM, and CM${\alpha}$, and this phenomenon was more pronounced by cordycepin-enriched CM${\alpha}$. The contents of total lipid, triglyceride, and free fatty acid in the serum were significantly or slightly lower in the OA control group than those of the N group, but there were no significant differences among the OA treatment groups. The hepatocytes in the OA-induced fatty liver contained numerous large lipid droplets, but PJ, CM, and CM${\alpha}$ feeding prevented the OA-induced lipid droplet accumulation in the hepatocytes. This effect was more pronounced in cordycepin-enriched CM${\alpha}$ than in PJ or CM in OA treatment rats. Accordingly, cordycepin-enriched CM${\alpha}$ could be an ideal candidate material as a dietary supplement in healthy functional foods to improve the effects of fatty liver.

The effects of linoleic acid(LA, 18 : 2) and/or bovine serum albumin(BSA) on the lipid metabolism in human hepatoma cell line HepG2 cells were evaluated. HepG2 cells were cultured in basal Dulbecco's modified Eagle's(DME) medium(Basal medium), DME medium containing 0.2 mM LA(LA medium), or DME medium containing both 0.2 mM LA and 0.2-1.0% BSA(LA+BSA medium). $[^{14}C]Acetate(0.3\;{\mu}Ci/ml\;medium)$ was added as a radioactive lipid precursor and the cells were incubated for 6 hours. An addition of LA to basal medium resulted in a decrease in the incorporation of $[^{14}C]acetate$ into total cholesterol fraction. In contrast, an addition of BSA to LA-containing medium tended to increase the incorporation of $[^{14}C]acetate$ into total cholesterol. The alteration of cholesterol metabolism in HepG2 cells incubated in LA+BSA medium was attributed by an increase in the incorporation of $[^{14}C]acetate$ into free cholesterol, but not cholesteryl ester fraction. In addition, the secretion of cholesterol was increased by LA+BSA medium, suggesting that BSA stimulates cholesterol secretion. No significant change in the incorporation of $[^{14}C]acetate$ into cellular total lipids was observed among the experimental groups. However, an increased incorporation of $[^{14}C]-labelled$ fatty acid into cellular triacylglycerol and decreased incorporation into phospholipid were observed in cells incubated with LA+BSA medium as compared to those of LA medium. The secretions of $[^{14}C]-labelled$ triacylglycerol, phospholipid, and free fatty acid were also stimulated in HepG2 cells incubated with LA+BSA medium. In conclusion, the present study suggests that in human hepatocytes, LA and BSA influence lipid metabolism, and BSA enhances the secretion of lipids.

This study was performed to examine the effects of Meju supplementation to high cholesterol diet on lipid metabolism in rats. Male Sprague-Dawley rats were divided into two groups(Steamed soybean, Meju) and were fed with 0.5% cholesterol diet. Serum and liver lipid profiles and fecal bile acids excretion were examined after four weeks of experimental diet. Food intake, weight gain and liver weight were not significantly different between the two groups. Total cholesterol concentrations in serum was significantly lower in Meju group compared to steamed soybean group(p＜0.05). HDL-cholesterol, triglyceride, phospholipids and nonestrified fatty acid concentrations in serum were not significantly different between the two groups. Cholesterol, triglyceride, and phospholipids concentrations in liver were not significantly different between the two groups. Fecal bile acid excretion were markedly higher in Meju groups than the group fed steamed soybean(p＜0.05). These results suggest that the cholesterol lowering effect by Meju supplementation might be resulted from the modulation of fecal bile acid excretion in rats.

This study was conducted to evaluate the effects of dietary conjugated linoleic acid (CLA) on the performance of lactating sows and piglets as well as the immunity of piglets suckling from sows fed CLA. Eighteen multiparous Duroc sows with an average body weight (BW) of $232.0{\pm}6.38kg$ were randomly selected and assigned to two dietary treatments (n = 9 for each treatment), control (no CLA addition) and 1% CLA supplementation. For the control diet, CLA was replaced with soybean oil. Experimental diets were fed to sows during a 28-day lactation period. Litter size for each sow was standardized to nine piglets by cross-fostering within 24 hours after birth. Sow milk and blood samples were taken from sows and piglets after 21 and 27 days of lactation, respectively. Loss of BW was significantly (p < 0.05) higher in sows fed control diet compared to sows fed CLA diet. Piglet weights at weaning and weight gain during suckling were significantly (p < 0.05) higher in sows fed CLA compared to sows fed control diet. Serum non-esterified fatty acid (NEFA) and urea nitrogen concentrations were significantly (p < 0.05) lower in sows fed CLA than in sows fed soybean oil. IgG concentrations of the groups supplemented with CLA increased by 49% in sow serum (p < 0.0001), 23% in milk (p < 0.05), and 35% in piglet serum (p < 0.05) compared with the control group. Sows fed CLA showed an increase of 10% in milk yield compared with sows fed soybean oil (p < 0.05), even though there was no difference in daily feed intake between the treatments. Milk fat content was significantly (p < 0.05) lower in sows fed CLA than in sows fed soybean oil. Solid-not-fat yield was significantly (p < 0.05) higher in sows supplemented with CLA than in sows fed control diet and also protein-to-fat ratio in milk was significantly (p < 0.05) higher in sows fed CLA compared with the control group. The results show that CLA supplementation to sows increased milk yield without losing BW during lactation, whereas soybean oil supplementation resulted in severe BW loss.

In order to establish a method predicting susceptible cows to the parturient syndrome, various serum chemical parameters (calcium, phosphorus, Ca/P, magnesium, cholesterol, total protein, albumin, globulin, A/G, total lipid, non-esterified fatty acid(NEFA) and aspartate aminotransferase(AST)) were measured during late pregnancy and their relationships with periparturient diseases were investigated during puerpural period. The results obtained were as follows : 1. The factors affecting the prediction of susceptible cows to parturient syndrome were calcium, magnesium, total protein, globulin, A/G ratio and total lipid at 30 day antepartum and the diagnosability was 70.7%. 2. In the experimental cows producing more than 21kg of milk per day, the factors affecting the prediction of susceptible cows to parturient syndrome were calcium, NEFA and A/G ratio at 30 day antepartum and the diagnosability was 66.7%. 3. In the experimental cows calved more than 3 times, the factors affecting the perdiction of susceptible cows to parturient syndrome were calcium, total protein, albumin and NEFA at 30 day antepartum and the diagnosability was 83.3%.

Italian ryegrass (Lolium multiflorum Lam.) was fractionated into leaf nutrient concentrate, fiber and deproteinised juice (DPJ). The fresh and fermented DPJs were concentrated and referred to as fresh deproteinised juice concentrate (FDPJC) and fermented deprotenised juice concentrate (FMTD DPJC). The FDPJC and FMTD DPJC were separately mixed with dried fiber and ensiled. Wilted crop silage and fresh fiber silage were also prepared from the same material crop. The nutritive value of these four silages were compared using four goats by $4{\times}4$ Latin square design. Green crop fractionation resulted lesser amount of crude protein and ash, and higher amount of neurtal detergent fiber, acid detergent fiber, cellulose and hemicellulose in fresh fiber. The pH of fresh fiber silage was lower than that of the other silages. Addition of FDPJC or FMTD DPJC to the dried fiber at ensiling did not improve the silage qualities; but all the silages were satisfactorily preserved. Goats fed these silages showed similar ruminal pH and total volatile fatty acid concentrations. But addition of FMTD DPJC was effective on increasing ruminal acetic acid concentration reducing propionic acid concentration. Ruminal n- and iso- butyric acid concentrations were proportional to that of propionic acid. High ammonia content of the silage containing FMTD DPJC was reflected to the ruminal ammonia concentration, urinary nitrogen excretion and serum urea level of goats. Inclusion of FDPJC or FMTD DPJC added 15 to 25% dry matter to the fiber silages with a little reduction in the digestibilities of most components of the silages.

The Framingham risk score (FRS) has been used to assess the risk of a cardiovascular event and to identify patients for risk factor modifications. Therefore, the purpose of this study was to evaluate the relationship of the FRS with dietary intake and inflammatory biomarkers. We conducted a cross-sectional study of 180 men ($49.2{\pm}10.2$ years) with MS. Serum levels of high sensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6), and adiponectin were examined. Participants were asked to complete the food frequency questionnaire (FFQ) using the previous 1 year as a reference point. The absolute cardiovascular disease (CVD) risk percentage over 10 years was calculated to estimate the FRS, which was classified as low risk (< 10%), intermediate risk (10-20%), and high risk (> 20%). Mean intake of polyunsaturated fatty acids was lower in subjects who had > 20% FRS than in subjects who had < 10% FRS ($3.7{\pm}1.9$ g/day vs. $4.7{\pm}1.9$ g/day; P < 0.05). Significant differences in the Index of Nutritional Quality of protein, phosphorus, iron, vitamin A, vitamin $B_1$, niacin, vitamin $B_6$, and vitamin C were observed between the > 20% FRS group and the < 10% FRS group (P < 0.05). IL-6 concentrations were significantly lower in subjects with a < 10% FRS than in subjects who were 10-20% FRS or > 20% FRS ($0.91{\pm}0.26$ vs. $1.48{\pm}033$ vs. $2.72{\pm}0.57$ pg/mL, respectively; P < 0.05). IL-6 and dietary intake of polyunsaturated fatty acids together explained 6.6% of the variation in FRS levels in a stepwise multiple regression model. Our results provide some evidence that dietary intake in the higher CVD risk group was inferior to that in the lower risk group and that dietary fat intake and IL-6 were associated with FRS and MS in Korean men.
