This research was aimed to manufacture the cholesterol free Mozzarella cheese with corn oil that contains high unsaturated fatty acid helping the reduction of serum cholesterol. Cheese stored at 1$0^{\circ}C$ was evaluated with general analysis, volatile free fatty acid, cholesterol, meltability, stretchability, color, rheological properties, and sensory evaluation. Moisture contents decreased during cheese storage period, whereas protein contents and pH value increased significantly (P < 0.05), but fat contents did not show any significant change. Linoleic acid was tile main volatile free fatty acid in a fat of cheese, and cholesterol contents were measured 4.34$\pm$ 0.04 mg/100 g in cheese. The meltability of cheese gradually increased during ripening, while the stretchability decreased. The color of cheese showed translucent yellow. Hardness, springiness, and cohesiveness increased significantly up to 21 days of storage. Compared to control cheese made by conventional way, QDA scores of shiny, oiling off, and melting of cholesterol free cheese were significantly different. These results suggested that health-oriented cholesterol free Mozzarella cheese would be made by addition of the corn oil.

In this study, dietary supplementations of Korean Meju, fermented soybean meal (F-SBM) by Aspergillus oryzae, and A. oryzae itself were evaluated on growth performance, feed utilization, immune responses and phosphorus availability in juvenile parrot fish, a marine aquaculture fish species. Four isonitrogenous and isocaloric diets were formulated to contain 8% soybean meal (control diet), 4% Meju (50% soybean meal was replaced by Meju), 4% F-SBM (50% soybean meal was replaced by F-SBM), or 0.08% A. oryzae itself. One of the four experimental diets was fed to triplicate groups of fish for 8 weeks. At the end of the feeding trial, no significant differences were found in growth performances and feed utilization. Red blood cell counts in the fish fed the A. oryzae diet were significantly higher than that of fish fed the control diet. The antioxidant activity in Meju diet was significantly higher than that of the control and A. oryzae diets. Fish fed Meju and F-SBM diets showed numerically higher antioxidant activity of serum compared to that of fish fed the control diet, even though it was not significant. Liver superoxide dismutase activity of fish fed the test diets was significantly higher than that of fish fed the control diet. The apparent digestibility coefficients of protein of fish fed all the diets were not significantly different. Phosphorus absorption was numerically increased in fish fed F-SBM and A. oryzae diets compared to that of fish fed the control diet. This study indicates that the fermentation process of soybean meal does not impair growth performance and feed utilization in parrot fish. The fermentation process could enhance the availability of phosphorus in soybean meal and non-specific immune responses of parrot fish.

This trial evaluated the effects of dietary supplementation with monensin sodium on dry matter intake, metabolic parameters and milk yield and milk composition of dairy Saanen goats in the periparturient period. Twelve Saanen pregnant dairy goats were assigned to a treatment and a control group. Saanen goats were fed monensin as its 10% sodium salt in the amount of 33 mg/kg of total dry matter intake during 30 d before parturition till d 42 in milk. Blood samples were collected from each goat at d 30, 15 and 7 before expected kidding time and also in d 1, 7, 13, 19, 21, 28, 35 and 42 postpartum. The serum concentrations of ${\beta}$-Hydroxybutyrate (BHBA), non-esterifed fatty acid (NEFA), calcium, magnesium, inorganic phosphorus, cholesterol, triglyceride, urea, total protein, albumin and glucose and aspartate aminotransferase (AST) activity were determined. The BHBA concentration significantly decreased in goats, which received monensin in comparison to controls in the postpartum period (p = 0.049). The concentration of sodium (Na) was significantly influenced by monensin treatment in the postpartum period (p = 0.048). In addition, the difference in dry matter intake was highly significant between the two groups during the pre-partum period. Controls had more dry matter intake (DMI) than treatment goats (p = 0.0001). Mean 3.5% fat corrected milk production was not influenced by monensin treatment. However, milk fat percentage was significantly decreased in monensin treated goats (p = 0.0017).

This study was conducted to evaluate the effects of indigenous herbal supplements on growth, blood metabolites and carcass characteristics in the late fattening period of Hanwoo steers. In a 6 month feeding trial, thirty Hanwoo steers ($647{\pm}32$ kg) were allotted to one of 5 treatment groups, control (basal diet contained lasalocid), licorice, clove, turmeric and silymarin, with six steers per pen. All groups received ad libitum concentrate and 1 kg rice straw/animal/d throughout the feeding trial. Blood samples were collected at the beginning, middle, and the end of the experiment and the steers were slaughtered at the end. Blood glucose, triglyceride, total protein, and albumin concentrations were higher in the turmeric treatment compared with other treatments. Blood urea nitrogen and creatinine concentrations were highest (p<0.003 and p = 0.071, respectively) in steers treated with silymarin. Alanine aminotransferase activity was lower (p<0.06) for licorice and silymarin compared with the control group. There were no alterations in serum aspartate aminotransferase and gamma glutamyltransferase activities as a consequence of herb treatments (p = 0.203 and 0.135, respectively). Final body weight, body weight gain, average dairy gain and dry matter intake were not significantly different among treatments. Yield grade, marbling score and quality grade were higher for silymarin group than those of the control group (p<0.05). Therefore, the results suggest that silymarin can be used an effective dietary supplement as an alternative to antibiotic feed additive and a productivity enhancer, providing safe and more consumer acceptable alternative to synthetic compounds during the late fattening period of steers.

The effects of the ginsenoside Rb2 (Rb2) on lipid metabolism were characterized in 3T3-L1 adipocytes to evaluate their utility for treating obesity. While the amounts of total cholesterol and triacylglycerol (TAG) were markedly increased in the adipocytes treated with high amounts of cholesterol and fetal bovine serum (FBS), the test groups treated with Rb2 showed levels that were close to normal. The effect of Rb2 on these cells was comparable to that of lovastatin. Rb2 enhanced the expression of the sterol regulated element binding protein (SREBP) mRNA whereas treatment with cholesterol and FBS led to a reduction in the abundance of this transcript. The activity of fatty acid synthetase (FAS) was lower in the cholesterol group compared to the Rb2 treatment group suggesting that the observed decrease in cholesterol levels and activated SREBP was mediated by Rb2. Treatment with Rb2 also resulted in a decrease in TAG levels in adipocytes cultured under high fatty acid conditions. This effect was mediated by stimulating the expression of SREBP and Leptin mRNA, suggesting that Rb2 might be a valuable component capable of lowering the levels of lipids.

The established methods in the residue analysis of endosulfan require an extensive sample clean-up prior to quantification by relatively complex equipment. A radioimmunoassay(RIA) provides a simple procedure with theoretically higher sensitivity and specificity necessitating only a minimum of sample clean-up. Endosulfan-specific antibodies were developed in rabbits by using a bovine serum albumin(BSA) conjugate wherein the alcohol form of endosulfan was multiply bound to the protein via succinylation. Produced antibodies showed the high titers to endosulfan-BSA(1 : 32,000). An RIA method was developed in water and carp by using $^{14}C-labeled$ endosulfan as a tracer. The lowest detection amount of endosulfan was 1 ng in the liver, kidneys, gut and water samples, and 3 ng in the whole body sample of carp without any clean-up, corresponding to 0.1 ppb of endosulfan.

We have expressed human erythropoietin (EPO) in transgenic mice using a recombinant EPO cDNA combined with a partial TPO construct. The gene was microinjected using standard techniques and five mice were detected as transgenic by PCR and further used as founders. The life span of the transgenic founders was much shorter than that of their normal littermates. Most of the tissues of the transgenic founders contained human EPO transcripts as judged by RT-PCR. Especially high expression levels were seen in the liver and lung. EPO protein levels in serum were examined by ELISA and ranged from 266-414 mIU/ml. The number of red blood cell, white blood cell and hemoglobin in the hEPO transgenic mice was higher than in normal mice. These results indicate that overexpression of hEPO is deleterious and can provoke lung failure and erythrocytosis.

Canine pyometra generally occurs in intact female dogs of more than four years of age. However, in rarely cases, pyometra can occur in young bitches. In the present report, two cases of pyometra in thirteen and eighteen months of age were presented. In both cases, absent of vaginal discharge represented that both patients had closed-cervix pyometra and diagnosis was somewhat complicated. In complete blood count, elevated level of leukocyte with left shift was found in both cases. Serum chemistry analysis showed elevation of alkaline phosphatase in both cases. Additionally, mild elevation of aspartate transferase and total protein were also found in $2^{nd}$ case. Radiographic and ultrasonographic findings show the enlargement of uterus and accumulation of fluid contents inside the uterine lumen. Ovariohysterectomy followed by antibiotics and anti-inflammatory drugs for post-surgery medication was performed for treatment. After a week, both patients fully recovered. To reduce mortality of pyometra in young intact female dogs, radiography or ultrasonography should be indicated immediately in the bitches showing severe infectious inflammation.

Objectives : The aim of this study was to investigate the effects of Gamisaenggan-tang on high fat diet induced nonalcoholic fatty liver disease. Methods: Rats were randomly divided into four groups. The Normal group was fed a solid diet containing 10% fat. The Gamisaenggan-tang (GS) group was fed a solid diet containing 10% fat and Gamisaenggan-tang (90mg/100g body weight). The Control group was fed a solid diet containing 60% fat. The HFD-Gamisaenggan-tang (HFD-GS) group was fed a solid diet containing 60% fat and Gamisaenggan-tang (90mg/100g body weight). Six weeks later, rats body weight, liver weight, serum ALT, GGT, ALP levels were measured. Histological findings (Oil red O staining), hepatic triglyceride, TNF-${\alpha}$, and TGF-${\beta}$ levels in the liver tissue were studied. Results: Average body weight of the HFD-GS group was significantly less than that of the Control group. There were no significant liver weight differences among each group. The GGT levels of the HFD-GS group were significantly less than those of the Control group. However, there were no significant differences in the ALT or ALP levels among the groups. TNF-${\alpha}$ protein production assessed by western blot analysis was reduced by Gamisaenggan-tang. Greater fat accumulation was observed in the liver tissue of the Control group than in the HFD-GS group, which means the Gamisaenggan-tang has an inhibitory effect on the accumulation of fat in the liver. Conclusion : The results suggest that Gamisaenggan-tang can be potential candidate for the treatment of nonalcoholic fatty liver disease in clinics.

Objectives: The aim of this study was to identify the validity of phase angle as a prognostic factor for survival in patients with metastatic cancer. Methods: Data of patients with metastatic cancer who visited the Korean medicine cancer center at Kyung Hee University Hospital in Gangdong from April 2016 to February 2018 were collected for this study. The values of phase angle (PhA) and blood hemoglobin (Hb), C-reactive protein (CRP), and serum albumin levels were also investigated by bioelectrical impedance analysis (BIA). Results: In total, 86 patients were analyzed. The cut-off value of the phase angle was determined as 5.0. Univariate and multivariate analysis revealed that phase angle (HR 3.15, 95% CI 1.79-5.54) and CRP (HR 2.15, 95% CI 1.24-3.73) predicted survival with statistical significance. The median overall survival of the low PhA group ($PhA{\leq}5.0$) was 1.8 months (95% CI 0.6-2.9 months) and 7.2 months (95% CI 5.2-9.2 months) in the high PhA group (PhA>5.0)(p<0.001). Conclusions: The phase angle could be an independent prognostic factor for patients with metastatic cancer. Further research is required to confirm these findings and their correlation with other indexes.
