This research was investigated the relationship, in high-producing Holstein donor cows, between the number of the transferable embryos and the blood serum concentrations of Blood Urea Nitrogen (BUN), glucose and cholesterol, which affect the nutritional state of cows. CIDRs were inserted into the vaginas of twenty two heads of Holstein cows, regardless of estrous cycle. Superovulation was induced using folliclar stimulating hormone (FSH). For artificial insemination, donor cows were injected with $PGF_{2{\alpha}}$ and estrus was checked about 48 hours after the injection. Then they were treated with 4 straws of semen 3 times, with 12-hour intervals. Embryos were collected by a non-surgical method 7 days after the first artificial insemination. The total numbers of ova collected from 3 experimental groups whose blood BUN concentrations were <10 mg/dl, 11~18 mg/dl and ${\geq}19$ mg/dl were 8.9, 12.5 and 19.0, respectively; whereas the numbers of transferable embryos were 5.8 + 1.9, 7.9 + 2.8 and 5.2 + 1.4, respectively. When glucose concentration was <60 mg/dl, the total number of collected ova was 9.9, which was smaller than when the concentration was 60~70 mg/dl or ${\geq}70$ mg/dl. When glucose concentration was 60~70 mg/dl, the number of transferable embryos was 7.1 + 2.4, which was slightly larger than the numbers 6.4 + 2.1 and 6.1 + 1.7 that were obtained when the concentrations were <60 mg/dl and ${\geq}70$ mg/dl, respectively ; however, the differences were not significant (p>0.05). When cholesterol concentrations were <150 mg/dl, 150~200 mg/dl and ${\geq}200$ mg/dl, the total numbers of collected ova were 11.2, 11.3 and 8.6, respectively. Whereas the numbers of transferable embryos were 7.1 + 2.1, 7.3 + 1.9 and 5.6 + 1.3, respectively ; however, the differences were again not significant (p>0.05). The result of this research showed no significant difference in ovum recovery rate and the number of transferable embryos according to major metabolite concentrations in high-producing Holstein donor cows. However, it is considered that the failure of maintaining proper nutritional status would cause the fall in in vivo embryo productivity.

Metabolic profile test is used to evaluate nutritional imbalance and metabolic disease in dairy cows. The reference intervals of metabolic parameters may change according to nation, region, decades, and maintenance system. Despite the need to be periodically updated for the reference intervals of metabolic parameters, it has rarely been investigated in Korea. Therefore, this aim of study was to provide the reference intervals of metabolic parameters using dairy cows surveyed in Korea during recent years. A metabolic profile test was conducted for 2,976 clinically healthy dairy cows in Korea. Blood samples were collected for the analysis of serum metabolites. This study provided reference intervals of thirteen metabolic parameters (${\beta}$-hydroxybutyrate [${\beta}-HB$], non-esterified fatty acids [NEFA], glucose, total cholesterol [T-COL], total protein, albumin, globulin, blood urea nitrogen [BUN], aspartate aminotransferase [AST], gamma-glutamyl transferase [GGT], calcium, phosphorus, and magnesium). BUN and AST values of the current study were higher than those of previous studies. In the present study, the other metabolic parameters showed low or similar value compared to previous results. Moreover, ${\beta}-HB$, NEFA, T-COL, ALB, BUN, AST, and GGT values were affected by lactation period. This study provided information on the reference intervals of metabolites in healthy dairy cows in Korea. The reference intervals from the present study would be useful in managing and diagnosing disease of dairy cows. However, careful attention should be given in interpreting disease condition for metabolites affected by lactation.

The present study investigated the physiological evaluation of cloned mini-pigs in a transportable isolator. Transportable isolator was designed and manufactured by our research team for transporting gnotobiotic pig. Until now, no previous reports are available regarding the physiological activities and harmful effects when pigs were transported in this isolator. Five cloned mini-pigs of 1~2 year (s) old female with a body weight between 80~90 kg were used. The effects of transportable isolator on stress-related hormone, adrenocorticotrophic hormone (ACTH) and cortisol levels, and heart rate were evaluated. In addition, it was also examined the effects of transportable isolator on blood chemistry factors (alanine aminotransferase: ALT, aspartate aminotransferase: AST, blood urea nitrogen: BUN, glucose, and creatinine). Blood was sampled just before the beginning of transport (T0), at the end of transport (30min after the transport; T1), and 30 min after the end of transport (T2). At the same time, heart rate was also evaluated. As a result, heart rate had no significant (p>0.05) differences at the various-time points of study (T0, T1, T2). However, heart rate was slightly higher than normal range in T1 and T2. The ACTH level was higher than normal range. Whereas, the cortisol level was lower than normal range. There were no statistical significant differences both ACTH and cortisol level between different time groups. Also, there were no significant differences in blood chemistry factors. Therefore, our present study shows that transportable isolator has no harmful effect on stress and physiological condition in cloned mini-pigs.

Recently, research has been focusing on high quality and safer animal production by utilizing natural functional materials. The aim of this study was to evaluate the effect of administration of natural Evening Primrose Oil (EPO) on gamma linolenic acid (GLA) levels in milk from Holstein dairy cows. Quality and quantity of milk as well as blood and fatty acids from Holstein cow fed diets supplemented with 2.7-4% calcium-salted EPO coated with palm stearin oil were analyzed. There was no significant difference in yield and composition of milk between control and EPO treatment. However, EPO treatment lowered blood aspartate aminotransferase (AST), somatic cell count (SCC), and cholesterol levels (p < 0.05) compared to untreated control. Blood urea nitrogen (BUN) level was decreased (p < 0.05) in GLA 1 and GLA 2 group when compared with control group. Non-esterified fatty acids (NEFA) concentration was lower (p < 0.05) in GLA 1 and GLA 2 groups than in control group. The level of GLA in milk was increased in EPO group when compared to control. Therefore, results from the present study demonstrate that supplementary EPO has beneficial effects on cow health, showing a decrease in somatic cell count and levels of blood cholesterol, alanine aminotransferase (ALT), and AST. Furthermore, supplementation of EPO improves milk quality with increased amounts of GLA.

This study was designed to determine the effects of larval extracts from Protaetia brevitarsis seulensis shade dried larva from Korea and China on liver tissues of hepatic injury groups. The experimental groups are divided into five groups; Normal, carbon tetrachloride single injection ($CCl_4$), Pb-CHI ($CCl_4$ + P. brevitarsis shade dried larva from China), Pb-KOR ($CCl_4$ + P. brevitarsis shade dried larva from Korea) and SIL ($CCl_4$ + 0.35% silymarin) groups. Sprague Dawley rats were oral injected with $CCl_4$ at a dose l mg/kg (20% in corn oil) for induction of liver damage for 4 weeks. Each experimental group was fed with a dose 50 mg/kg of larval extracts based on medicinal preparations from 3 weeks to 4 weeks after $CCl_4$ treatment. At the end of 4 weeks, we evaluated the serum levels of glutamate-oxaloacetate transaminase (GOT), glutamate-pyruvate transferase (GPT), alkaline phosphatase (ALP) and blood urea nitrogen (BUN) in serum and the cytokine levels of tumor necrosis factor-${\alpha}$) (TNF-${\alpha}$) and transforming growth factor-${\beta}$ (TGF-${\beta}$) in the cells isolated from spleen and liver. The histological analysis was also conducted. The $CCl_4$ injection reduced body weight, induced congestion of middle lobe and hepatocytic degeneration, resulting in disintegration of hepatic cords, and increased biochemical markers of blood related to hepatic injury. On the other hand, the Pb-CHI and Pb-KOR group decreased the levels of biochemical markers in blood and cytokine levels in spleen and liver. Especially, the Pb-KOR group facilitated the recovery of biochemical values of blood related to hepatic injury, hepatic lesions and fibrosis. Taken together, larval extract from P. brevitarsis might prevent acute hepatotoxicity and enhance the recovery of liver fibrosis and cirrhosis induced by $CCl_4$, and the ingredients could be a promising candidate for the prevention and treatment of hepatic disorders.

The purpose of this study is to inspect trends of the paper of Korean medical treatment on Carbon Tetrachloride-induced Hepatotoxicity and try to establish the future direction for development of Korean herbal medicine. We reviewed 79 papers which had been published from 1981 to 2010 in journals published in Korea. According to these studies, Carbon Tetrachloride-induced hepato-celluar degeneration and necrosis induced to increase in serum aspartate amintransferase (AST), alanine aminotransferase (ALT), Alkaline phosphatase (ALP), ${\gamma}$-Glutamyl transferase (${\gamma}$-GTP), lactate dehydrogenase (LDH), bilirubin, blood urea nitrogen (BUN) and albumin levels. In biochemical analyses, antioxidant enzymes such as superoxide dismutase (SOD), Glutathione S-transferase (GST) and catalase in hepatic tissue were remarkably incresed by Carbon Tetrachloride treatment. We found that some of the herbal extracts have a protective effect against Carbon Tetrachloride-induced Hepatotoxicity. More studies of oriental medicinal herbs are required for developing a treatment of hepatotoxicity.

Renal failure means irreversible damage and depression of renal function, represented by glomerular filtration rate(GFR). A renal failure patient with uremia and anemia is presented. Anemia, in this patient, appeared before uremia did. A 55 year-old male patient was treated for renal failure with Weilingtang. Improvement was observed in, not only GFR, blood urea nitrogen(BUN), and creatinine, but also in such symptoms as difficulty in urine excretion, dyspepsia and abdominal swelling. But anemia appeared during treatment, so a mixture of Dangguibuxuetang(當歸補血湯) and Xiongguitang(芎歸湯) was prescribed. After this treatment, improvement in hemoglobin, and hematocrit was observed.
