Collagen peptide plays a protective role in skin by increasing the activity of antioxidant, acts like an activator of skin regeneration by positive feedback and is used as a potent candidate for cosmetics or functional food. GABA acts at inhibitory synapses in the brain by binding to specific transmembrane receptors of both pre- and postsynaptic neuronal processes in vertebrates, is also involved in the synthesis of melatonin and might exert regulatory effects on sleep and reproductive functions. In this study, we investigated the beneficial effect of a mixture of collagen peptide and GABA (J85091900) on skin and sleep condition in woman experiencing sleep disorder. We found that oral supplement with J85091900 significantly decreased the value of Pittsburgh Sleep Quality Index (PSQI), increased sleeping time by 7%, and also improved skin roughness (Ra, Rz, Rt), periorbital wrinkle (Ra, Rt), and skin capacitance in human. These findings indicate that dual strategy with which skin improvement is accomplished using collagen peptide and sleeping well is acquired using GABA could be the novel solution for sleeping beauty by edible cosmetics to improve skin status.

This study was conducted to determine the effect of a mixture of two water-soluble dietary fibers, psyllium husk and glucomannan, on serum lipids, fecal fat excretion and body fat. Twenty one female Sprague-Dawley rats were randomly assigned into three groups (control, pair-fed control and test group) and fed a high saturated fat (20% lard) diet (control diet) or a test diet (psyllium husk and glucomannan added to the control diet at the level of 0.9% and 0.68%, respectively) for 8 weeks. Pair-fed control rats were allowed to eat the amount of diet consumed by test group the preceding day. The body weight gain and food efficiency ratio of test group were significantly lower compared with these of control group. The mean values of body weight gain and food efficiency ratio were lower in test group than in pair-fed control group, but the difference was not significant. There were no differences in food intake. The dry weight and water content of feces and fecal fat excretion were markedly greater in test group than in control groups. Serum total cholesterol and triacylglycerol levels were significantly lower in test group than in two control groups.1'he rats of two control groups had higher body fat contents than that of test group. These results indicate that the combination of the two water-soluble dietary fibers, psyllium husk and glucomannan, can be used as a potent lipid-lowering agent in individuals consuming high saturated fat diet.

This study examined the effects of Bulnesia sarmienti ethanol extract on lipid metabolism in streptozotocin (STZ)-induced diabetic rats. Sprague Dawley rats were induced with diabetes mellitus by injecting STZ (45 mg/kg) into the tail vein, and were then divided into 5 groups: normal, STZ-control, and three experimental diabetic groups. The rats were fed a basal diet along with B. sarmienti ethanol extract for 8 weeks. According to the results, after 8 weeks of consuming the experimental diets, the body weights and food efficiency ratios of the B. sarmienti ethanol extract-fed groups were not different from those of the control group. However, the concentrations of plasma total-cholesterol, LDL-cholesterol, and triglycerides were significantly lower in the B. sarmienti ethanol extract groups as compared to those of the control group. Although a blood glucose control effect was not observed after the eight weeks of B. sarmienti ethanol extract treatment in this type-l diabetes model, it was discovered that the experimental diets were highly effective at lowering levels of serum lipids, including triglycerides, total-cholesterol, and LDL-cholesterol.
This study was conducted to investigate the effects of dietary supplementation of garlic by-products on performance, proximate composition, carcass characteristic, cholesterol, and blood composition of chickens. Broiler chicks were fed diets for 5 weeks with a diet 1% garlic by-product (T1), 2% garlic by-product (T2), and 5% garlic by-product (T3). There were no difference among diet in performance. In proximate composition, crude fat of chicken meat was decreased in diets by addition of garlic by-product than control, but moisture and crude ash were no significant difference. Liver weight was significantly increased (P<0.05) by the dietary supplementation with garlic by-products compared to the control diet. The total cholesterol and LDL-cholesterol of treatment groups was lower than control, and the HDL-cholesterol of treatment groups was higher than control (P<0.05). Especially, T3 was significantly (P<0.05) more effective in improving cholesterol compared to other treatment groups. In blood composition, GOT of broiler was decreased in diet by garlic by-products than control group, but GPT, triglyceride, and glucose were no significantly different. In conclusion, these data indicate that supplementation of garlic by-products (T3) were most effective in decreasing total cholesterol, LDL-cholesterol, and GOT and increasing HDL-cholesterol.

This study was designed to determine the effect of different floor space and type of finishing building on performance, behaviour and carcass quality of finishing pig. Three hundred and thirty six finishing pigs were alloted into two space allowance ($1.0m^2$and $2.5m^2$/pig) and two floor type (concrete slat and bedded with sawdust) of finishing building. There was no significant difference between the different space allowance in the body gain, feed intake and feed per gain. And also floor type of finishing building was not affected by the performance of finishing pig. Space allowance per pig affected the maintenance behaviour, but there was no significant difference between the floor type of finishing building in the spent time on lying, sitting and standing. Floor type was affected by the occurrence of standing behaviour, the finishing pigs in the bedded with sawdust showed less occurrence of standing. Carcass traits did not show any significant difference due to the difference of space allowance and floor type of finishing building. There was no significant difference in the chemical compositions of pork loin between the space allowance and floor type of finishing building.

This study was performed to investigate the repeated-dose toxicity of Leuconostoc citreum GR1 (Leuc. citreum GR1), a lactic acid bacterium isolated from kimchi, in male and female rats. Sprague-Dawley male and female rats were divided into four group (ten animals in each group) and Leuc. citreum GR1 was administered daily by gavage to rats at dosage levels of 0, 500, 1,000, or 2,000 mg/kg/day for four weeks. There were no bacterial-related deaths or abnormal clinical signs in either gender of rats during the observation period. Furthermore, no differences were found between the control and treatment groups in terms of body weight, food intake, and water consumption. Hematological parameters, serum biochemical analysis, and histopathological examination also showed insignificant dose-dependent alterations. There were also no alterations in organ weights upon administration of Leuc. citreum GR1 alone. These results suggest the oral application of Leuc. citreum GR1, up to a dosage level of 2,000 mg/kg, causes no adverse effects in both male and female rats.

This experiment was conducted to investigate the effects of supplemented diets with Malty Culture(MC) during lactation on sow and litter performance. Eighteen lactating sows were randomly assigned to three dietary treatments(basal diet, basal diet+MC0.5%, basal+MCl.0%). Average daily feed intake of sow was not affected by dietary treatments with treatment means ranging from 4.49 to 4.58kg(p>0.62). All sows lost their backfat thickness during lactation with no difference among the treatments(p>0.25). Fecal moisture was similar for sows fed the control and MC treatments with 70% moisture content. The growth rate of piglets was not significant difference among the treatments ranging from 47 to 48kg. Day to estrus postweaning was not affected by supplementation of MC with treatment means ranging from 5 to 7 days. There was not significant difference in the milk production(i.e, 8.9kg/d for control, 9.18kg/d for MC0.5 and 9.20kg/d for MC1.0). Survivability of piglet was affected by feeding added MC during lactation. There was no significant difference in the digestibility of DM, but the digestibility of N tended to increase in sows fed the MC0.5 and MC1.0 supplemented diets compared to the basal diet(linear effect, p<0.10; quadratic effect. p<0.08). Digestibility of P tended to increase by the treatment of supplemented MC. However, there was no significant difference among the treatments. In conclusion, the results of experiment suggest that lactation diet of supplemented MC could be a beneficial feeding for digestibility in sow and litter performance.
We investigated the effects feeding illite on growth performance and meat quality characteristics in finishing pigs. Forty-eight pigs ($Landrace{\times}Yorkshire{\times}Duroc$; $68.3{\pm}1.6 kg$ average initial body weight) were used in a 50 day experiment. Pigs were randomly placed into one of four experimented diet groups (0, 0.2, 0.5 and 1% illite) and were slaughtered at approximately 110 kg live weight. Although there were no significantly differences in daily weight gain, feed intake and feed conversion between controls and groups fed illite, those values were increased as increasing of illite concentration in feed. Carcass weight, carcass ratio and backfat thickness were not affected by dietary illite supplementation. However, the percentage of A grade carcasses were significantly increased by dietary supplement of 1.0% illite. There were no significantly differences in moisture, crude protein and crude ash between controls and groups fed illite, but the crude fat of 1.0% illite supplemented groups was significantly lower than other groups (p<0.05). All muscles from control and treatment groups had normal pH 5.55-5.68. However, lightness ($L^*$) values of pork decreased as increasing illite supplement. Whereas red-ness ($a^*$) and yellowness ($b^*$) values were not significantly changed. In fatty acid composition, palmitoleic acid and linoleic acid were significantly higher in 1.0% illite dietary group, saturated fatty acid was decreased and unsaturated fatty acid was increased by 0.5-1.0% illite supplementation.
This study was performed to investigate the four-week repeated-dose toxicity of the crude antifungal compounds produced by Lactobacillus plantarum AF1 (Lb. plantarum AF1), a lactic acid bacterium isolated from kimchi, in male and female rats. Sprague-Dawley male and female rats were divided into four groups, with 10 animals in each group. The test article was administered once daily by gavage to rats at dosage levels of 0, 500, 1,000, and 2,000 mg/kg/day for four weeks. There were no test-article-related deaths or abnormal clinical signs in both the male and female rats during the observation period. Furthermore, no differences in the body weight changes, food intake and water consumption levels of the control and treatment groups were found. The hematological parameters, serum biochemical analysis results, histopathological examination results and all other findings also showed no significant or dose-dependent changes. There were also no changes in the organ weights upon the administration of the crude antifungal compounds produced by Lb. plantarum AF1. These results suggest that the oral administration of the crude antifungal compounds produced by Lb. plantarum AF1 had no adverse effects up to a dosage level of 2,000 mg/kg in both male and female rats.

Two diet energy levels (high or low) and two bedding material (rice husk or saw dust) treatments were designed for either male or female slow-growing Korean meat-type chicken (Hanhyop 3) to make totally eight treatments for 11~75 d feeding trial. Body weight gain (BWG) were influenced by energy levels, sex of bird and bedding material type. There were interaction effect among those three factors. Feed intakes (FI) by male bird during each and overall periods were higher than those by female. Diet energy levels and bedding material affected the FI only during final 56~75 d period, of which FI of high energy diet was higher in male whereas that of low energy diet was higher in female. Although feed conversion ratio (FCR) was improved by high energy diet, the better FCR has dissipated during 41~75 d, when the most of overall BWG were achieved. Apparent total tract retention (ATTR) of nutrients were higher in male than those in female birds with exception on fat ATTR. Fat ATTR was improved when fed low energy diet regardless of the sex of birds. Both energy levels and sex of bird influenced the color of breast. Thiobarbituric acid reactive substances (TBARS) value of female thigh was higher than that of male. Levels of moisture and P in female thigh were lower although level of fat in female breast was higher than those in male, respectively. This study showed that diet energy levels for Hanhyop 3 chicken, especially during 41~75 d, should be differently formulated between male and female bird.
