The purpose this study was to investigate the influences of 5% turmeric (Curcuma longa L.) supplementation on enzyme activities such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), amylase, lipase and catalase in serum of dyslipidemic rats. Sprague-Dawley (SD) rats (24 male) were divided into four groups, namely the ND group (normal-nondyslipidemic diet), NT group (normal-nondyslipidemic diet+5% turmeric), DD group (control-dyslipidemic diet), and DT groups (dyslipidemic diet+5% turmeric). Serum concentrations of blood urea nitrogen (BUN), creatinine and uric acid were significantly decreased (p<0.05) by turmeric supplementation diet. The activities of AST, ALT, ALP, LDH, amylase and lipase in sera of turmeric diet group were significantly decreased (p<0.05). The catalase activity in serum of turmeric supplementation group was significantly increased than dyslipidemic diet (p<0.05). In vivo experiment with dyslipidemic rats showed that ingestion of turmeric were effective in kidney and hepatic functional enzyme activities. Which suggests that turmeric material could be used for further studies as a potential source for nutraceutical foods.

The objective of this study was investigate the superovulation treatment and to relate concentrations of blood urea nitrogen(BUN) in Hanwoo donors. Thirty six, at random stages of the estrous cycle, received a CIDR. Four days later, the animals were superovulated with a total of 28AU FSH (Antorin, 2AU=1 ml) administered twice daily in constant doses over 4 days. On the 3th administration of FSH, CIDR was withdrawn and 25 mg $PGF_2a$ was administered. Cows were artificially inseminated twice after estrous detection at 12 hr intervals. The cows received $100\;{\mu}g$ GnRH at the time of 1st insemination. Embryos were recovered 7 or 8 days after the 1st insemination. Cows with BUN <10, 11~18 and ${\geq}$19 mg/dl had return of estrus of 34.6, 30.5 and 30.4 days respectively. Return of estrus after superovulation treatment was not significantly lower for cows with blood urea nitrogen (BUN) above 10 mg/dl than for cows with BUN below 10 mg/dl. Cows with BUN <10, 11~18 and ${\geq}$19 mg/dl had number of transferable embryos of $3.2{\pm}1.2$, $5.4{\pm}1.9$ and $4.1{\pm}2.1$ respectively.

The purpose of this study was to investigate the improvement effect of mung bean (Phaseolus aureus L.) on the hepatic functional enzyme and catalase activity of streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley (SD) male rats were divided into four groups (n=6), and fed experimental diets containing mung bean meal [basal diet+5% mung bean (BM), basal diet+STZ+5% mung bean (SM)], and control (Basal Diet, BD), BS groups (basal diet+STZ). Serum concentrations of Blood Urea Nitrogen (BUN) and creatinine were significantly decreased (p<0.05) by 5% mung bean supplementation diet. The activities of aspartate transaminase (AST), alanine transaminase (ALT), akaline phosphatase (ALP), lactate dehydrogenase (LDH), amylase and lipase were decreased in the BD, BM and SM group than BS group. The catalase (CAT) activity was significantly increased (p<0.05) in mung bean supplementation diet (BM, SM group) than diabetic group (BS). In vivo experiments with diabetic rats showed that ingestion of mung bean supplementation diet were effective in BUN concentration, and hepatic functional enzyme activities.

In an attempt to define the early biochemical determinants that participate in the pathogenesis of glycerol-induced nephrotoxicity, especially focusing on oxygen free radicals, we studied malondialdehyde (MDA) level and the activities of catalase and superoxide dismutase in the renal cortex of rats, and the concentrations of blood urea nitrogen(BUH) and serum creatinine of rats at 24hr after the injection of a 50% solution of glycerol. Sprague-Dawley albino rats weighing 240 to 260 mg were injected intramuscularly with a 50% solution of glycerol(2 mι/kg, 4 mι/kg and 8 mι/kg). The group treated with glycerol showed significantlv higher MDA level and catalase activity, lower SOD activity and higher BUN and serum creatinine concentrations at 24 hr after the injection as compared to those of control group. These results suggest that the excessive oxygen free radicals resulting from the depression of SOD activity is an important determinant in the pathogenesis of glycerol-induced nephrotoxicity.

Components of cholesterol, glucose, minerals (selenium, Ca, p) and vitamin E in blood and milk were collected and analyzed weekly after calving from a total of 78 Holstein cows. In this study, we examined changes of chemical components, correlations among them, and factors affecting the changes. The results were summarized as follows; 1 Average levels of components in blood during 9 weeks after calving were 178.8 mg/dl, 62.3 mg/dl, 8.9 mg/dl, 7.4 mg/dl, 52.2 ng/ml, $10.3{\mu}g/ml$, 16.3 mg/dl, 15.3 ng/dl, and 15.8 mg/dl for cholesterol, glucose, Ca, P, selenium, vitamin E, BUN (blood urea nitrogen), MSe (milk selenium), and MUN (milk urea nitrogen), respectively. 2. The levels of cholesterol, glucose selenium, vitamin E and MSe tended to increase over time after calving. 3. The estimated correlations among components were negative(-) for cholesterol and p, positive for selenium, and BUN and also positive for BUN and MUN. Glucose showed positive correlations with P and MSe. 4. For factors influencing the changes of components, there were significant differences in glucose and selenium for age, in selenium and vitamin E for parity, in glucose and MSe for milk and in all components except Ca and selenium for feeding grass and hay, respectively. In urea nitrogen, age and parity only showed significant difference in MUN. In conclusion, the results were suggested that changes of blood and milk components depend on feeding during the postpartum. Especially, we could ascertain that selenium in blood and milk is the important factor for the dairy cows after parturition.

Thirty nine pregnant Javanese thin-tail ewes (20 and 19 carried a single and multiple [2 to 3] fetuses, respectively), and six nonpregnant ewes as controls were used to measure maternal serum hormone and blood metabolite concentrations as predictors of number of fetuses carried during pregnancy. Serum hormones (progesterone, estradiol, triiodothyronine, and cortisol) and blood metabolites (b-hydroxy butyric acid [BHBA], and blood urea nitrogen [BUN]) were determined every four weeks during pregnancy and were used to predict litter size by discriminant analysis. The results of data analysis indicated that serum progesterone and estradiol concentrations at weeks 8, 12, 16 of pregnancy could be used to predict the number of fetuses carried with precision of 86.7 to 95.6%. Serum triiodothyronine, cortisol, BHBA, and BUN concentrations during pregnancy, however, were not good predictors of the number of fetuses carried. Serum progesterone and estradiol concentrations as early as 8 weeks of pregnancy in sheep could predict the number of fetuses carried with 86.7% precision.

Calf diarrhea is a major health concern in the livestock industry that requires accurate analysis for appropriate treatment. Dehydration and electrolyte imbalance are the most significant consequences of diarrhea in calves. Until now, the reference values of blood analysis of Hanwoo neonatal calves have not been well known. Recently, portable blood analyzers have made it possible to immediately analyze blood in the farm and provide suitable treatment for the patients. We analyzed electrolytes, blood urea nitrogen (BUN) and glucose in the blood of 179 Hanwoo neonatal calves, including 79 with diarrhea. These 179 calves were divided into 3 groups based on their age. Values of sodium (Na⁺ ) and glucose were significantly lower in diarrheic calves (1~30 days), while potassium (K⁺ ) and chloride (Cl^- ) values were higher in diarrheic calves (1~30 days). BUN values, which are closely related to dehydration due to diarrhea, increased in diarrheic calves of all ages. Therefore, these data can be used as reference values for blood analysis and treatment of healthy or diarrheic Hanwoo neonatal calves within 30 days of age.

This study is aimed to investigate the change of serum compositions of mice caused by the irradiation. The 3Gy radiation with 10MeV Linac was once irradiated to whole body of mice and their serum was collected to conduct 14 biochemical analyses. With the collected data, t-test was performed. As the result, the significant change was confirmed in the following 3 compositions. First, the glucose level of the normal control group was $185.43{\pm}14.93$, but the irradiation group was found to be $220.00{\pm}17.58$, which shows significant difference(p<0.001). Second, the BUN(blood urea nitrogen) measurement showed lower value($15.70{\pm}1.48$) in the irradiation group than the normal control group($19.61{\pm}1.65$), which indicates the significant difference in mean value (p<0.01). Third, the measurement of albumin resulted in lower value of $2.89{\pm}0.25$ in irradiation group than $3.19{\pm}0.34$ of the normal control group, which shows the significant difference in mean value(p<0.05). In consequence, the serum of the mice irradiated with 3Gy radiation caused significant change in 3 compositions; glucose, Blood urea nitrogen(BUN) and albumin.

The aim of this study was to investigate the hematology and serum chemistry values on Sprague-Dawley rats, used krill (Euphausia superba) meal diet and sodium fluoride (NaF) for 5 weeks. Seven-week-old male rats were divided into five groups and fed experimental diets containing three krill meal contents, administrated orally 10 mg of NaF, basal diet group (BG), basal diet plus 10 mg of NaF group (BFG), 10.0% krill meal plus 10 mg of NaF group (KMF10), 20.0% krill meal plus 10 mg of NaF group (KMF20), and 30.0% krill meal plus 10 mg of NaF group (KMF30). Concentrations of non-esterified fatty acid (NEFA), blood urea nitrogen (BUN), creatinine in sera were significantly lower in the KMF10, KMF20, KMF30 than BFG (p<0.05). In uric acid concentration KMF10 showed no significant difference with the BFG group, was significantly lower than KMF20 and KMF30 (p<0.05). Total calcium (T-Ca) concentrations was all observed to be no significant difference, was increased with krill meal content (p<0.05). Phosphorus (Pi) concentration was no change in the content of krill meal. Accordingly, krill meal was considered to be effective in improving NEFA and BUN, creatinine, uric acid concentration.

The objective of this study is to investigate the changes in concentrations of blood urea nitrogen (BUN) and sex steroid hormones, such as estrogen, progesterone, and testosterone in Korean cattle (Hanwoo) with reproductive disorders and to examine the relationship between BUN and body condition score (BCS) in Hanwoo. The concentration of BUN was 16.2 mg/dl, 17.8 mg/dl, 15.1 mg/dl, 17.9 mg/dl, and 28.3mg/dl in pregnancy, repeat breeding, follicular cyst, luteal cyst, and ovarian atrophy, respectively. In Hanwoo with BCS $2.0{\sim}2.9$, $3.0{\sim}3.5$ and $3.6{\sim}4.0$, the concentration of BUN was 15.8 mg/dl, 17.0 mg/dl, and 17.6 mg/dl, respectively. Fluoroimmunoassay showed that serum estrogen and progesterone levels were decreased in reproductive disorders Hanwoo, such as ovarian atrophy, endometritis, and weak estrus. The testosterone level was significantly decreased in Hanwoo with reproductive disorders compared to that in pregnant Hanwoo ($0.02{\sim}0.03\;ng/ml$ vs 0.13 ng/ml, p<0.05). The progesterone and estrogen concentrations in follicular fluid obtained from ovary with follicular cyst were significantly higher (p<0.05) than those in normal follicle fluid. These results show that there is no relationship between BUN and BCS in Hanwoo, and the concentration of sex steroid hormone in serum and follicular fluid are changed in reproductive disorders Hanwoo.
