The difference in lipid metabolism between breast-fed(BF) and formula-fed(FF) infants were studied in 31 Korean infants at 1, 2 and 3 months postpartum. The formulas had more total lipids(TL), triglycerides(TG) and phospholipids and less cholesterol(CHOL) and free fatty acids(FFA) than the breast milk. The milk consumption of the FF infants was significantly greater than that of the BF infants with a wide individual variation. As a result, the FF infants appeared to consume more TL, TG and PL and less CHOL and FFA than the BF infants during 3 months. The lipid contents of the breast milk tended to decrease in due course of lactation, therefore the intake of lipids of BF infants was reduced during the first three month of lactation. The plasma TG and CHOL levels of infants at 3 month were not significantly different between the BF and FF infants, but the PL level of the BF infants was higher then that of the FF infants. The plasma levels of TG and CHOL were not significantly correlated with the intakes of TL, TG, CHOL, PL and FFA, respectively. The PL level, however, was positively correlated with the intakes of CHOL and FFA, respectively and negatively correlated with PL intake as well as 18 : 2w6 fatty acid content of the breast milk or the formulas. The fecal weight and fecal loss of TL of the FF infants were greater than those of the BF infants during 3 months, however, apparent lipids digestibility was not significantly different between the BF and FF infants. The fecal excretions of CHOL and bile acids of FF infants were substantially higher than those of BF infants during 3 months. New sterol balance showed a particularly large difference between the BF and FF infants. The value of the net sterol balance of the BF infants was negative, but that of the FF infants was positive. This study shows that the consumption pattern of various lipid components of BF and FF infants were different as a result of different lipid compositions between breast milk and formula. The significantly lower sterol balance of the BF infants than the FF infants may have been derived from the unique dietary characteristic of breast milk.

Objective: To investigate the association of individual follicular fluid (FF) leptin and adiponectin levels with the quality of the corresponding oocyte and embryo. Methods: We prospectively enrolled 67 women who underwent controlled ovarian hyperstimulation with 89 FF samples. FF and the corresponding oocyte was obtained from a single dominant preovulatory follicle at the time of oocyte retrieval. Concentrations of leptin and adiponectin were measured by enzyme-linked immunosorbent assay in an individual follicle. The oocyte quality, fertilization rate, and corresponding embryo development were assessed. Results: The FF level of leptin was significantly associated with body mass index (r=0.334, p<0.01). The FF adiponectin level was significantly higher in the normal fertilization group than the abnormal fertilization group (p=0.009) in the non-obese women. A lower FF leptin level was associated with a trend toward mature oocytes, normal fertilization, and good embryo quality, although these relationships were not statistically significant. The leptin:adiponectin ratio of FF did not differ significantly according to oocyte and embryo quality. The quality of the oocyte and embryo was not associated with the FF leptin level tertile. However, the normal fertilization rate was positively associated with FF adiponectin level tertile. There was a trend towards improved oocytes and normal fertilization rates with the lowest tertile of the FF leptin:adiponectin ratio, but this difference was not statistically significant. Conclusion: Our results suggest that a high FF adiponectin concentration could be a predictor of normal fertilization. However, the FF leptin concentration and leptin:adiponectin ratio is not significantly related to oocyte maturity and corresponding embryo development.

These studies were carried out to investigate the effect of gonadotropins (GTH), fetal calf serum (FCS), porcine follicular fluid (pFF) and FCS and pFF fractions obtained by the gel filtration on in vitro maturation of porcine follicular fluid. When the oocytes were cultured in TCM-199, the maturation rate was higher in pFF than in FCS in both with or without GTH and in pFF the maturation rate was higher in with GTH than in without GTH. In case of without GTH, pFF increased maturation rates in TCM-199, but not in Whitten's medium (WM). When the oocytes were cultured in WM supplemented with FCS fractions, the maturation rate(51.6%) of oocytes was significantly (P<0.05) higher in fraction B (about 30∼70 kDa) than in control, FCS and other fractions. When oocytes were cultured in WM supplemented with pFF fractions, fractions B (about 30∼70 kDa) and D (about 1∼10 kDa) were significantly (P<0.05) higher than in control, pFF and other fractions. In conclusiion, the addition of gonadotropins into the maturation media was effective for oocyte maturation. The addition of pFF was more effective than addition of FCS for maturation of porcine oocytes in vitro. And fraction B from FCS and fractions B and D from pFF was effective for oocyte maturation.

Korean breast-fed(BF) and formula-fed (FF) infants(n=31) were studied at their age of 1, 2 and 3 months to compare their intakes of energy, protein, lipid and lactose. Formulas had more energy, protein and lipid than breast milk, but the former had less lactose than the latter. The milk consumption of the FF infants was, however, greater than that of the BF infants with wide individual variation. As a result, the FF infants took in more energy, protein and lipid than the BF infants except lactose. The total daily caloric intakes(kcal/day) of the BF infants were 521.418 and 425 at their age of 1, 2 and 3 months respectively, and those of the FF infants were 676.752 and 723(at their age of 1, 2 and 3 months respectively). Daily protein intakes(g/days) of the BF infants were 9.5, 8.0 and 7.6 at their age of 1, 2 and 3 months respectively, and those of the FF infants were 13.9, 15.5 and 14.8(at their age of 1, 2 and 3 months respectively). The energy and protein of both the BF and the FF infants were deficient compared to the present Recommended Nutrient Allowances, and the deficiency of the BF infants was greater than that of the FF infants. But the energy intakes per kg of body weight of the FF infants at their age of 1 and 2 months were more than the present recommended energy allowances. And the protein intake per kg of body weight of the FF infant at the age of 1 month was the same as the present recommended protein allowances.

목적 MRI Dixon method (이하 DIXON) 기법을 이용하여 슬관절 지방우세 골조직의 지방신호분율(fat signal fraction; 이하 FF)을 구하고 골밀도(bone mineral density; 이하 BMD)와 상관관계 분석을 시행하였다. 대상과 방법 본원 슬관절 DIXON 영상을 촬영한 환자들 중 일 년 이내의 dual energy X-ray absorptiometry가 있는 환자 93명을 후향적으로 분석하였다. DIXON 영상에서 원위부 대퇴골 골간단(femur metaphyseal; 이하 Fm)과 근위부 경골 골간단(tibia metaphyseal; 이하 Tm)의 FF를 계산하였다. FF와 BMD 간 상관관계를 분석하였다. 또, 요추(lumbar spine; 이하 L), 대퇴경부(femoral neck; 이하 FN), 총대퇴골(femur total; 이하 FT)의 BMD 별로 나누고 FF에 대하여 Kruskal-Wallis H test를 시행하였다. 결과 전체 환자군에서 TmFF와 FN-BMD 사이에 유의미한 음의 상관관계를 보였다(r = -0.26, p < 0.05). 여성 환자에서는 TmFF가 FN-BMD, FT-BMD 및 L-BMD와 음의 상관관계를 보였다(r = -0.38, -0.28과 -0.27, p < 0.05). 남성 환자에서는 FmFF가 FN-BMD 및 FT-BMD와 음의 상관관계를 보였다(r = -0.58과 r = -0.42, p < 0.05). 여성 환자들을 세 군으로 나누었을 때 TmFF에 유의한 차이를 보였다(p < 0.05). 남성 환자들을 두 군으로 나누었을 때, FmFF이 군간에 유의미한 차이를 보였다(p < 0.05). 결론 슬관절 주변의 FF와 BMD는 음의 상관관계를 보였으며, DIXON을 이용한 FF 측정이 BMD 스크리닝에 사용될 수 있는 가능성을 보였다.

The aim of this study was to investigate the effect of fermented fruits (FF) on the growth performance, Enterobacteriaceae and Lactobacillus counts in faeces of the post-weaning piglets. A total of twenty-four 4 weeks old Landrace${\times}$ Large White${\times}$Duroc with initial body weight of 6 kg were used in this study. The piglets were housed individually in metabolic cage and randomly assigned to four groups with six piglets per group. The piglets were fed on basal diet without antibiotic (AF), basal diets with antibiotic (Ab), basal diet with 10% (w/w) fermented fruit (10% FF) and basal diet with 20% (w/w) fermented fruit (20% FF). Faecal samples were taken directly from the rectum of each piglet and cultured for Enterobacteriaceae and Lactobacillus counts. In the growth performance, the piglets of Ab and 10%FF had significantly higher (p<0.05) average daily gain than those of 20%FF. However, no differences (p>0.05) were observed between AF, Ab and 10%FF. Studies showed that the use of fermented fruits (FF) could significantly (p<0.05) reduce Enterobacteriaceae population in piglets' faeces compared to the use of normal feed (AF) and antibiotic (Ab). However, the Lactobacillus population in the faeces was increased in those piglets fed with diets added with FF.

The possible effect of human follicular fluid(hFF) on the growth and development of fertilized oocytes and embryos is important because the fallopian tubes are exposed to FF after follicular rupture and the processes of fertilization and embryo cleavage occur inside the fallopian tubes. Previously, it was suggested that human FF might adversely affect on the development of early mouse embryos. In order to investigate the effect of hFF on the development of embryos, early mouse embryos were cultured in media containing various protein sources as bovine serum albumin(BSA), fetal cord serum(FCS) and FF. And we evaluated the development of early mouse embryos in terms of the morphology, cleavage rate, and cell count of blastcysts. There were no significant differences in the morula and blstocyst formation rates of 2-cell mouse embryos cultured in the media containg three different protein sources and three different concentrations of FF. The blastocyst formation rate of 1-cell mouse embryo cultured in FF group was significantly higher than that cultured in BSA group(P<0.05). The morula and blastocyst formation rates of 2-cell mouse embryos of the group cultured in the media containing FF were comparable with those of other two groups, in addition, the cell count of blastocysts of FF group in the 2-cell embryo culture was higher than those of BSA group and HCS group(P<0.01), and this finding was also noted in 1-cell embryo culture. There was no difference in the morula and blastocyst formation rates of the 2-cell mouse embryos cultured in the media containing different concentrations of FF. These results suggest that mature human follicular fluid has no inhibitory activity on the development of early mouse embryos even in high concentration and may be a good protein source which is positively associated with the development of mouse embryos in vitro especially in 1 cell embryo culture.

The present work is aimed to evaluate the protective effect of glutathione-enriched Saccharomyces cerevisiae FF-8 strain on carbon tetrachloride ($CCl_4$)-induced hepatotoxicity and oxidative stress in rats. The activities of liver markers (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenase), lipid peroxidative index (thiobarbituric acid-reactive substances), and the antioxidant status (reduced glutathione) were used to monitor those protective roles of FF-8 strain. The liver marker enzymes in plasma and the lipid peroxidation in the liver were increased when $CCl_4$ was treated but these were significantly decreased by FF-8 strain treatment. The hepatic concentration of glutathione in the current glutathione-enriched FF-8 strain fed animal was approximately twice as high as the normal, but this was slightly increased in response to $CCl_4$ plus glutathione-enriched FF-8 strain. The increased liver triglyceride concentration due to the $CCl_4$ treatment was significantly decreased by FF-8 strain and the reduced level reached to that of normal group. Administration of FF-8 strain in normal rat did not show any signs of harmful effects. Therefore, the current findings suggest that FF-8 strain could be an effective antioxidant with no or negligible side-effects and it might be useful for the purpose of protection treatment of hepatotoxicity and oxidative stress in $CCl_4$-treatment in rat.
