  • The amount and type of dietary protein that effects affect bone mineral loss after menopause and different dietary patterns may influence anthropometric measurements, biochemical values, and bone metabolism. Objective : Our objective was to investigate bone metabolism and chronic disease factors in two different dietary patterns. Design: The sample consisted of 40 lacto-ove-vegetarians(LOV) and 49 omnivores aged from 47 to 85 years in good condition without any medical problems. Results : The average energy intake of LOV was 1414.0kcal and omnivores, 1403.2kcal. The difference between means was not statistically significant. The differences of means of body weight and BMI between the two groups were not significant but the systolic blood pressure of LOV group was significantly lower than omniovores(p<0.05). The values of serum cholesterol(p<0.05) and glucose(p<0.05) of LOV were signifcantly lower than that of omnivores. The serum albumin level(p<0.01) of LOV was lower than it'scounterpart but in a normal range. The intake of crude fiber(p<0.05) of LOV group was significantly higher. The urinary pH of LOV was 7.4 and that of omnivores was 6.3(p<0.001). Plant calcium(p>0.05) and plant iron(p<0.001) had positive correlations with the uninary pH but animal protein(p>0.05) and animal iron(p>0.05) had negative correlations with the urinary pH. The level of urinary biochemical marker of bone resorption, deoxypyridinoline(DPD) of LOV was significantly lower than the other group(p>0.05). The T-scores of bone mineral density for the two sites in the two groups were not significantly different. Conclusions : The DPD level and urinary pH value of LOV were more desirable for the bone metabolism that the omnivores. The diet of LOV had lower risk factors of chronic diseases than the other group.

  • Purpose: Human milk oligosaccharides (HMOs) may be genetically determined based on the secretor and Lewis status of the mother. This study aims to determine the HMO profile and the secretor and Lewis gene status of Indonesian lactating mothers. Methods: Baseline data of 120 mother-infant pairs between 0-4 months post-partum obtained from a prospective longitudinal study was used. The concentrations of 2'-fucosyllactose (2'FL), lacto-N-fucopentaose I (LNFP I), lacto-N-tetraose (LNT), lacto-N-neotetraose (LNnT), 3'-sialyllactose (3'SL), and 6'-sialyllactose (6'SL) were measured. Genetic analysis was performed for mothers using targeted next-generation sequencing and Sanger sequencing. Wild-type AA with the rs1047781 (A385T) polymorphism was categorized as secretor positive, while heterozygous mutant AT was classified as a weak secretor. The presence of rs28362459 (T59G) heterozygous mutant AC and rs3745635 (G508A) heterozygous mutant CT genes indicated a Lewis negative status, and the absence of these genes indicated a positive status. Subsequently, breast milk was classified into various groups, namely Group 1: Secretor+Lewis+ (Se+Le+), Group 2: Secretor-Lewis+ (Se-Le+), Group 3: Secretor+Lewis-(Se+Le-), and Group 4: Secretor-Lewis- (Se-Le-). Data were analyzed using the Mann-Whitney and Kruskal-Wallis rank tests, and a p-value of 0.05 indicated statistical significance. Results: A total of 58.3% and 41.7% of the samples had positive and weak secretor statuses, respectively. The proportion of those in Group 1 was 85%, while 15% were Group 3. The results showed that only 2'FL significantly differed according to the secretor status (p-value=0.018). Conclusion: All Indonesian lactating mothers in this study were secretor positive, and most of them had a Lewis-positive status.

  • Four strains of lactic acid bacteria which had cholesterol lowering activities were selected from foreign fermented milk. The strains were identified as Lactobacillus(L.) rhamnosus 2084, L. casei 0781, Lactococcus (Lacto.) lactis spp. 204, and Enterococcus(E.) faecium 402. We observed that the L. rhamnosus 2084 was the most tolerant against pH 1.5, L. casei 0781 against pH 2.0, but not significantly different in the tolerance against pH 3.0. The L. rhamnosus 2084 was the most tolerant against bile acid and prominent in the degree of lowering cholesterol level. All four strains were used as starters in producing yogurt, and then investigated physico-chemical characteristics, such as pH, titratable acidity, and viable cell counts of yogurt base. L. casei 0781, L. rhamnosus 2084, Lacto. lactis 204, and E. faecium 402 were incubated for 6 hours at $40^{\circ}C$, 4 hours at $40^{\circ}C$, 6 hours at $37^{\circ}C$, and 12 hours at $37^{\circ}C$ and $40^{\circ}C$, respectively, for the optimum conditions of fermented milk.

  • The longitudinal changes on human milk volume per day and lactational performance of 23 Korean lacto-ovo-vegetarians(primiparae=11, multiparae=12) from 0.5 to 5 months after parturition have been studied by test weighing method. The human milk volume per day tended to increase during lactation. The mean volume (SD, ml/day) at 0.5, 1, 2, 3, 4, 5 months were 502(102), 692(127), 697(100), 684( 125), 757(52), 703(70), respectively. The overall mean volume was 661$\pm$132ml/day. The peak milk volume during the lactation was observed at most lactating women at the 1st month. The distributions of the individual mean volume during the first 5 months of lactation were found over 750m1(8.7% ), 650-750ml(47.9% ), 550-650m1(2l.7% ), and 450-550ml(2l.7% ) The number of feeding per day was 8.1 ($\pm$1.0) at 0.5 months postpartum, which was consistently decreased. However, the mean volume per feeding was increased from 62($\pm$9.5)ml at 0.5 month to 112($\pm$13.3)ml at 5 months postpartum. The milk volume was correlated with the peak volume. and maternal age. but not with weight before delivery. maternal height and birth weight. No differences of milk volume and lactational performance between facto-ovo-vegetarian and nonvegetarian women were observed. This study suggests that the human milk volume cited in the recommended dietary allowances for Koreitns is over estimated.

  • Glucose syrup and lactose, mixed with citric acid as a polymerizing catalyst, was processed using twin screw extruder, in which 40 of L/D(length/diameter) ratio was designed to provide sufficient retention in extruder for polymerization of sugars. The polymerization yields of glucose syrup were 36.90%, 55.44% and 77.10% at 160, 180 and 20$0^{\circ}C$, respectively, while those of lactose were 26.45%, 38.16% and 45.86% at the same temperatures. Gel permeation chromatography exhibited that the higher molecular weight fractions were increased with extrusion temperature, which also led to increasing hydrodynamic intrinsic viscosity. Both uco-oligosaccharides and lacto-oligosaccharides produced by extrusion of glucose syrup and lactose were stable for thermal treatments over a wide range of pH3.0~11.0. In addition, $\alpha$-amylase and amyloglucosidase treatment of gluco-oligosaccharides did not affect the solution viscosity, indicating the random linkage rather than $\alpha$-1, 4 linkages of glucose and thus the potential applications as a dietary fiber. In this research it was clearly observed that twin screw extrusion can be successfully utilized to produce gluco-oligosaccharides and lacto-oligosaccharides rapidly and continuously in conjunction with selective control of polymerized composition.

  • In this study longitudinal of the taurine content in the human milk of 23 Korean lacto-ovo-vegetarian women was studied during the lactating periods of the 15th, 30th, 60th, 90th, 120th and 150th day after delivery. The results of the study on primiparae and multiparae studied separately are as follows: 1) The taurine content of the primiparae per 1ml of human milk was 356.1nmole on the 15th day, 238.6 nmole on the 30th day, 249.6 nmole on the 60th day, 148.7 nmole on the 20th day, and 139.6 nmole on the 150th day. There was a significant decrease in the measns. 2) The taurine content of the multiparae per 1ml f human milk was 401.6 nmole on the 90th day, 189.9 nmole on the 120th day, and 159.8 nmole on the 150th day. There was a significant decrease in the measns. 2) The taurine content of the multiparae per 1ml of human milk was 401.6 nmole on the 15th day, 342.3 nmole on the 30th day, 273.2 nmole on the 60th day, 248.6 nmole on the 90th day, 189.9 nmole on the 120th day, and 159.8 nmole on the 150th day. There was a significant decrease in the measns. The multipareas had higher taurine content in every lactating period than the primiparae but there was not a significant difference. The correlation between the changes durinig lactating periods and the taurine content was negative. The correlation coefficient of the primiparae was -0.641 and that of the multiparae was -0.753. The overall correlation coefficient of the primiparae and the multiparae is -0.644, decreasing significantly up to the 150th day.

  • Total spleen lymphocytes, lymphocyte proliferation, tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), and interleukin-10 (IL-10) in spleen lymphocyte culture were studied in malnourished Wistar rats fed with goat milk yoghurt. Malnourished rats were created by using standard feed restriction as much as 50% of normal rats for 21 d. Goat milk yoghurt containing three types of microorganism e.g., Lactobacillus acidophilus, Sterptococcus thermophilus and Bifidobacterium longum derived from Lacto-B culture in powder form. After 21 d, the rats continued to receive restricted feeding and supplemented with goat milk yoghurt for 7 d. Total splenocytes were counted by hemocytometer. Splenocytes proliferation was expressed as stimulation index, whereas the TNF-${\alpha}$ and IL-10 of spleen lymphocyte culture were measured by ELISA technique. The total number of splenocytes and stimulation index of splenocytes in moderate malnourished and normal rats supplemented with goat milk yoghurt was not significantly different. The level of TNF-${\alpha}$ in the rat supplemented with goat milk yoghurt was lower (p<0.05) than the control group, whereas the level of IL-10 in the rat supplemented with goat milk yoghurt was higher (p<0.05) than the control group. In conclusion, goat milk yoghurt supplementation in malnourished rats could decrease TNF-${\alpha}$ as a representation of the pro-inflammatory cytokine, while it increases IL-10 as a representation of the anti-inflammatory cytokine.

  • The oligosaccharides in human milk constitute a major innate immunological mechanism by which breastfed infants gain protection against infectious diarrhea. Clostridium difficile is the most important cause of nosocomial diarrhea, and the C-terminus of toxin A with its carbohydrate binding site, TcdA-f2, demonstrates specific abolishment of cytotoxicity and receptor binding activity upon diethylpyrocarbonate modification of the histidine residues in TcdA. TcdA-f2 was cloned and expressed in E. coli BL21 (DE3). A human milk oligosaccharide (HMO) mixture displayed binding with TcdA-f2 at 38.2 respond units (RU) at the concentration of 20 μg/ml, whereas the eight purified HMOs showed binding with the carbohydrate binding site of TcdA-f2 at 3.3 to 14 RU depending on their structures via a surface plasma resonance biosensor. Among them, Lacto-N-fucopentaose V (LNFPV) and Lacto-N-neohexaose (LNnH) demonstrated tight binding to TcdA-f2 with docking energy of −9.48 kcal/mol and −12.81 kcal/mol, respectively. It displayed numerous hydrogen bonding and hydrophobic interactions with amino acid residues of TcdA-f2.

  • Objectives: The purpose of this study is to review and evaluate the effectiveness of oriental medicine per oral for recurrent vulvovaginal candidiasis (RVVC). Methods: We searched articles from Korean journal databases including Journal of Korean Obstetrics and Gynecology, Korean studies Information Service Studies, and Chinese National Knowledge Infrastructure, Cochrane Library, PubMed. Searched keywords were "재발성 칸디다성 외음질염", "recurrent vulvovaginal candidiasis", "㚆发性外阴阴道假丝酵母菌病", "中藥". Results: 10 randomized controlled trials with 700 patients were identified and reviewed. 8 studies compared combination of oriental medicine and anti-fungal agent with anti-fungal agent, and 6 of them reported that treatment group (TG) showed statistically higher total effective rate or cure rate and lower recurrence rate. One study compared oriental medicine and anti-fungal agent and TG showed statistically higher total effective rate and lower recurrence rate after 1 month. One study compared combination of oriental medicine and lacto bacillus capsule with lacto bacillus capsule, and TG showed statistically higher total effective rate and lower positive fungul test rate after 6 months. No severe adverse response was reported. Conclusions: Our review found that oriental medicine per oral is effective for alleviating symptoms, lowering recurrence rate and positive fungal test in RVVC patients. We recommend standardized randomized controlled trial guideline should be made to obtain stronger evidence and well designed trials with larger sample sizes are needed.
