Purpose: Preterm infants are very susceptible to malnutrition because of a lack of storage of nutrients, immature digestion and metabolism, and accompanying diseases associated with prematurity. The purpose of this study was to evaluate the effects of nutritional support by the pediatric nutritional support team (pNST) on the clinical course of preterm infants in the neonatal intensive care unit (NICU). Methods: Between July 2003 and July 2006, 48 preterm infants who were admitted to the NICU at Seoul National University Bundang Hospital were included. The subjects were divided into the following two subgroups according to the presence of NST activity; pre-NST group (n=23) and NST group (n=25). Hospital records were reviewed retrospectively. Results: Forty-eight preterm babies were included (M:F=27:21; gestational age, 25~33 weeks). A dietician, pharmacists, or the pNST participated in the prescription of total parenteral nutrition (TPN) more rapidly in the NST group (p=0.000). The fasting periods and TPN administration periods were significantly decreased in the NST group compared to the pre-NST group (p=0.017 & p=0.001, respectively). The doses of calories, protein, and lipids administered via TPN were significantly increased in the NST group compared to the pre-NST group (p=0.016, p=0.000, and p=0.000, respectively). The total period on antibiotic therapy was significantly decreased in the NST group compared to the pre-NST group (p=0.007). Conclusion: Because nutritional support by the pNST is of benefit to the clinical course of preterm infants in the NICU, the pNST should recommend to improve the nutritional status and clinical outcome of preterm infants.

This study was. conducted to investigate the effects of $\delta$-aminolevulinic acid supplementation on growth. performance, nutrient digestibility and hematological changes in weaned pigs. Seventy five Duroc${\times}$Yorkshire${\times}$ Landrace pigs (7.21$\pm$0.02 kg average BW) were used in a 20 d growth assay. Dietary treatments included 1) NC (negative control; basal diet), 2) PC (positive control; NC diet + 0.1% Apramycin + 0.1% Oxytetracycline), 3) ALA0.l (NC diet+0.l% $\delta$-aminolevulinic acid), 4) ALA0.2 (NC diet+0.2% $\delta$-aminolevulinic acid) and 5) ALA + AB (PC diet+0.2% $\delta$-aminolevulinic acid). In entire experimental period, ADG (Average Daily Gain) was greater in pigs fed ALA + AB diet than in pigs fed NC diet (p<0.05). However, there was no significant difference in ADG for pigs fed PC, ALA0.l or ALA0.2 diets. Also, ADFI (Average Daily Feed Intake) and G/F (Gain/Feed) were not affected by treatments. For 20 d, fecal digestibilities of DM (Dry Matter) and N (Nitrogen) were higher (p<0.05) for pigs fed ALA + AB diet than for pigs fed NC and ALA0.l diets. Total protein concentration of serum was increased in ALA + AB treatment compared to NC and PC treatments (p<0.05). In iron concentration of serum, pigs fed $\delta$-aminolevulinic acid supplementation diets were greater than for pigs fed NC and PC diets (p<0.05). TIBC (Total Iron Binding Capacity) concentration of serum was increased in ALA + AB treatment compared to NC, PC and ALA0.l treatments (p<0.05). Pigs fed ALA + AB and ALA0.2 diets were higher hemoglobin (Hb) and hematocrit (HCT) concentration of blood than pigs fed NC and PC diets (p<0.05). RBC and WEC concentrations of blood were significantly higher (p<0.05) for the pigs fed ALA0.2 and ALA + AB diets than for pigs fed NC diet. Lymphocyte concentration of blood was increased in $\delta$-aminolevulinic acid supplementation treatment compared to NC treatment (p<0.05). In conclusion, $\delta$-aminolevulinic acid supplementation for weanling pigs had improved growth performance and nutrient digestibilities and had increased total protein, iron, hemoglobin and lymphocyte concentration of blood. Also, feeding for dietary $\delta$-aminolevulinic acid and antibiotic mixture supplementation may have more higher effective growth performance in weanling pigs.

This experiment was selected a $\beta$-glucan producing mushroom strain and developed industrial media, and used to $\beta$-glucan as an alternative for antibiotics in weaned pigs. Yields of mycelial biomass and extracellular $\beta$-glucan from Youngji (Ganoderma lucidum) mushroom was 8.52g/L and 4.49g/L respectively. Also, we prepared optimum formula for mushroom cultivations. A total of 144 pigs ($8.6{\pm}0.9$ kg average body weight, weaned $20{\pm}3$ days of age) were allotted to 4 different treatment groups and replicated 4 times with 8 pigs per replicate in randomized complete block design. Treatments were T1) NC (negative control, basal diet), T2) PC (positive control, basal diet+0.255% antibiotics), T3) NC+0.2% $\beta$-glucan and T4) PC+0.2% $\beta$-glucan. The T2 and T4 treatments were significantly higher in feed efficiency by antibiotics group (p<0.05), however, there was no significant differences in terms of average daily gain (ADG) and average daily feed intake (ADFI) during phase I (0~14 days). In phase II (15~28 days), Pigs fed with antibiotics and $\beta$-glucan (T4) had greater ADG than other treatments (p<0.05), while no differences were observed in ADFI and feed efficiency. During the whole experiment period, the ADG of T4 treatment was higher than other treatments. Pigs fed with $\beta$-glucan (T3 and T4) had greater diarrhea score and moisture content than other treatments (p<0.05). Pigs fed with $\beta$-glucan (T3 and T4) had greater moisture content than other treatments (p<0.05). However, there was no significant differences in diarrhea score and mortality of weaned pigs. There was marginal reductions in feed cost measured feed cost per weight gain used in antibiotics and $\beta$-glucan added diet during phase I. In the second phase, the treatment supplemented with antibiotics had a significantly lower feed cost per weight gain compared to the other treatments. The results from these experiments suggests that $\beta$-glucan is likely able to improve the growth performance, and reduce feed cost although they do not have similar effects like antibiotics in weaning pigs.
Purpose : Fungal infection is one of the important causes of morbidity and mortality in patients with hematologic malignancies. Amphotericin B(ABV) and itraconazole(ITZA) have been used as the standard empirical antifungal therapy in neutropenic patients with acute leukemia who have persistent fever that does not respond to antibiotic therapy. ABV is an antifungal drug associated with side effects such as fever and chills, symptoms which may be mediated by pro-inflammatory cytokines such as interleukin-$1{\beta}$(IL-$1{\beta}$) and tumor necrosis factor-${\alpha}$(TNF-${\alpha}$). We assessed modulation of these pro-inflammatory cytokines as well as the anti-inflammatory cytokines(IL-4, IL-1Ra) by ABV and ITZA. Methods : From March 2004 to February 2005, a total of 30 episodes from acute leukemia patients with febrile neutropenia were analyzed for this study. They were randomly allocated to receive intravenous ABV or ITZA for 14 days. Clinical responses were evaluated at the completion of therapy, and cytokine IL-$1{\beta}$, TNF-${\alpha}$, IL-4, and IL-1Ra were measured for determination to know the correlation between two antifungal agents and inflammatory cytokines. Results : Empirical antifungal agents were given to 37 patients(ABV 20, ITZA 17), and 30 patients(ABV 15, ITZA 15) were evaluable for efficacy. White blood cell and absolute neutrophil count in the group treated with ITZA increased early days of treatment, so the duration of neutropenia in ITZA group is shorter. Serum creatinine level is lower in ITZA group than in ABV group but this is not statistically significant. There was no significant difference in response rate between two groups. The IL-$1{\beta}$ was increased in ABV treatment group and the ratio of IL-1Ra/IL-$1{\beta}$ is markedly decreased in ABV treatment group while increased in ITZA group. Conclusion : ITZA and ABV have at least equivalent efficacy as empirical antifungal therapy in neutropenic children with acute leukemia. However ITZA is associated with significantly less toxicity in clinical and molecular aspects.
We evaluated the growth performance, biochemical characteristics, and immune responses in weaning pigs given a diet containing MR-1 (0.2%/feed) or antibiotics (0.1%/feed) for 45 days. In vitro study showed that MR-1 has antibacterial activity against a variety of strains of pathogenic bacteria, especially a strain of cattle-derived Escherichia coli K99 (E. coli K99) by agar diffusion assay. In the in vivo model, 0.2% MR-1-given group clearly ameliorated the weight gain and feed efficiency in the growth performance of weaning pigs compared to the basal diet group (p<0.05). Additionally, 0.2% MR-1 induced an elevation in the levels of mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) and showed a similar pattern ($TNF{\alpha}$ and $IFN{\gamma}$ production) to the antibiotic treated pigs. Taken together, we suggest that 0.2% MR-1 makes probiotics an alternative to antibiotics in weaning pigs.

Purpose: Survival after liver transplantation (LT) has improved over the years, but infection is still a major complication. We aimed to identify the characteristics of bacterial infections in pediatric LT recipients. Methods: This study is a retrospective review of 189 consecutive children undergoing LT between 2000 and 2015 at a single center. In this study, the incidence of infection was determined for the following periods: within 1 month, between 1-5 months, and between 6-12 months. Patients who underwent liver transplants more than once or multiple organ transplants were excluded. Results: All patients had received postoperative antibiotic for 3 days. Only the maintenance immunosuppression with oral tacrolimus and steroids were performed. As a result, 132 bacterial infections developed in 87 (46.0%) patients (0.70 events per person-year). Bacterial infections occurred most frequently within the first month (n=84, 63.6%) after LT. In the pathogens, Staphylococcus aureus (15.2%), Enterococcus species (15.2%), and Klebsiella species (13.6%) were most common. Regarding the organ infected, bloodstream was most common (n=39, 29.5%), followed by peritoneum (n=28, 21.2%), urinary tract (n=25, 18.9%), and lungs (n=20, 15.2%). We changed prophylactic antibiotics from ampicillin-sulbactam to piperacillin-tazobactam at 2011, October, there were no significant effects in the prevalence of antibiotics resistant bacterial infections. The 1-year mortality was 9.0% (n=17), in which 41.2% (n=7) was attributable to bacterial infection; septicemia (n=4), pneumonia (n=2), and peritonitis (n=1). Conclusions: The incidence and type of bacterial infectious complications after LT in pediatric patients were similar to those of previous studies. Bacterial complications affecting mortality occur within 6 months after transplantation, so proper prophylaxis and treatment in this period may improve the prognosis of LT.
This experiment was designed to evaluate effects of Dandelion (Taraxzcum coreanum) and Dandelion fermented probiotics medium on the growth performance and meat quality in broiler chicks. A total of 150 "Ross" broilers,1-day old, were assigned to 5 treatments in a completely randomized design. There were 5 replications per treatment and 6 broilers in each replication for 5 weeks. The dietary treatments included a control (Dandelion and Dandelion fermentation was not added), antibiotic (0.05 chlortetracycline was added), 1.0% Dandelion supplementation and 0.5 and 1.0% Dandelion fermented probiotics, respectively. There was no significant difference in final body weight, weight gain, feed intake, and feed conversion ratio of broilers fed diets containing antibiotics, 1.0% Dandelion supplementation and 0.5 and 1.0% Dandelion fermented probiotics. The total cholesterol, HDL and LDL in plasma and meat cholesterol content was not affected by 0.5 and 1.0% Dandelion fermented probiotics and 1.0% Dandelion supplementation (P>0.05). The oleic acid content was significantly increased in 0.5% Dandelion fermented probiotics compared to that of the control (P<0.05). As a result, Dandelion and Dandelion fermented probiotics result in the influence on decreasing cholesterol in blood, particularly when adding probiotics, oleic acid that is the important factor in taste testing of meat increases thus the quality and taste of the chicken meat could be improved with the effect.
This study was conducted to investigate the effects of modification of a herbal recipe(Herb $Mix^{(R)}$) on the growth of pullet and laying performance of hens. The formula of Herb $Mix^{(R)}$, a mixture of Rehmannia glutinosa, Angelica gigas, Discorea japonica, Glycyrrhiza uralensis, Schisandra chinensis and Ligusticum jeholense, was modified in mixing ratio. A total of 1,120 pullets(Hy-Line Brown) of 14 wks old were assigned to seven treatments; control, Herb $Mix^{(R)}$(HM), R. glutinosa fortified HM, A. gigas fortified HM, D. japonica fortified HM, G. uralensis fortified HM, S. chinensis fortified HM, L. jeholense fortified HM and Flavomycin supplemented diet. Each treatment had 8 replicates of 20 birds each housed in 2 birds cages. Body weight at 10% egg production was significantly(P<0.05) influenced by treatments. Birds fed A. gigas fortified HM diet were heaviest followed by L. jeholense fortified HM, HM-original and D. japonica fortified HM, Flavomycin supplemented diet and R. glutinosa while those fed control diet were lightest. Also, age reaching 50% egg production and peak production was earliest in A. gigas fortified HM and latest in the control. Egg production, feed intake, feed conversion and egg weight were significantly influenced by treatments. Significant improvement in egg production and feed intake was shown in A. gigas fortified HM treatment. Feed conversion ratio was lowest in antibiotic(Flavomycin) treatment and egg weight was heaviest in L. jeholense fortified HM treatment. There were no significant differences among treatments in intestinal microflora but cfu of Cl. perfringnes and E. coli tended to be lower in HM treatments than the control. Among the leucocytes of blood, the HM treatments were lower than the control in counts of white blood cell and heterophils. It was concluded that modification of Herb $Mix^{(R)}$ fortifying with A. gigas, D. japonica and L. jeholense significantly influence growth and laying performance of birds.

This study attempted to identify the possibility of natural herbal extracts as an alternative, preventive agent of caries by comparing antimicrobial activities between natural herbal extracts and mouth rinsing solutions against Streptococcus mutans. Natural herbal plants were extracted with distilled water and ethanol, respectively, to measure the minimum growth inhibitory concentration of S. mutans depending on concentration, and among which, solvents showing high antimicrobial activity were selected to compare their antibiotic effects with those of mouth rinsing solutions. Also, to determine the concentration of natural medicinal herbs that can be used safely in the oral cavity, the extracts were treated to the normal gingival fibroblast cells depending on concentration in order to determine its cytotoxicity using MTT. In terms of the minimum growth inhibition concentration, the growth inhibition of S. mutans was more excellent in the ethanol extract than in the distilled water. When the minimum growth inhibition concentration was compared, Psoralea corylifolia of natural herbal ethanol extracts, and Hexamedine (Bukwang Pharm., Korea) of mouth rinsing solutions inhibited growth of S. mutans at the lowest concentration. When the minimum bactericidal concentration was compared, P. corylifolia of natural herbal extracts, and Hexamedine and Garglin (Dong-A Pharm., Korea) of mouth rinsing solutions eliminated S. mutans at a low concentration. The human gingival fibroblast was treated with natural herbal ethanol extracts at the minimum growth inhibition concentration of 10, 39, and $78{\mu}g/ml$. As the result, no cytotoxicity was found. When this was treated at different minimum bactericidal concentrations, natural herbal ethanol extracts showed cytotoxicity except P. corylifolia.
We examined saury, herring, gizzard shad kwamaegi to measure of microbic contamination rate of kwamegi that are sold in the market now. In the total bacteria, staphylococcus, peroxide value, and microorganisms is inhibited that from sample that we treated a substance with chitosan-ascorbate (CA) and other orders deep water (DW), ginseng steamed red and wine (GRW), NT (not treated). When we compared between SGRW and SNT, SCA show us more inhibition effect 0.22-0.49 log cycle in the total aerobacter. When we compared between HDW and HNT, HCA restraint 0.05-0.45log cycle, and when we compared between GDW and GNT, GCA inhibited 0.45 log cycle. In the coliform and E. coli, growths of microorganisms were inhibited followed order by treatment of CA, NT, and DW. GDW, HCA and HNT checked enough amount of water from the moisture measurement; but SGW, GCA, HEW and SCA showed 7-15% lack of moisture, and SNT and GNT have 10% more moisture. Peroxide value is changed to 41-51meq/kg when we did treat CA in there and a side that didn't add antimicrobial expressed the result numerically that 56-58meq/kg. In the sensory evaluation, customer gave preference to followed by Saury kwamaegi, herring, and gizzard shad kwamaegi. We have a point of view when kwamaeki manufactured if we add natural antibiotic and it uses to vacuum drying, we would inhibited of multiplication of microorganism, and of peroxides.
