This study estimated the effect of exposure to propiconazole through implementation and residues in finishing pigs. We analyzed the expression of fibrosis-related genes and performed histological analysis of the blood, liver, kidney, muscle, ileum, and fat tissues. The animals were exposed for 28 d to different concentrations of propiconazole (0.09, 0.44, 0.88, 4.41, and 8.82 mg/kg bw/d). Quantitative, gene expression, and histological analyses in tissues were performed using liquid chromatography mass spectrometry, real-time PCR, and Masson's trichrome staining, respectively. Final body weight did not differ among groups. However, genes involved in fibrosis were significantly differentially regulated in response to propiconazole concentrations. Glucose, alanine aminotransferase, and total bilirubin levels were significantly increased compared with those in the control group, while alkaline phosphatase level was decreased (p<0.05) after exposure to propiconazole. The residue limits of propiconazole were increased in the finishing phase at 4.41 and 8.82 mg/kg bw/d. The liver, kidney, and ileum showed blue staining after propiconazole treatment, confirmed by Masson's trichrome staining. In conclusion, these findings suggest that propiconazole exposure disturbs the expression of fibrosis-related genes. This study on dietary propiconazole in pigs can provide a basis for determining maximum residue limits and a better understanding of metabolism in pigs and meat products.

Mirror carp Cyprinus carpio nudus (weight 42.0±3.8 g, length 14.3±0.4 cm) were exposed to different concentrations of waterborne copper (0, 100, 200, 400, 800, and 1,600 ㎍ Cu²⁺·L^-1) at 20.3℃ for 96 h. The lethal concentration 50 of waterborne copper was 1,176.45 ㎍ Cu²⁺·L^-1. Among hematological parameters, red blood cell count was significantly decreased, whereas there were no significant changes in the hemoglobin concentration and hematocrit value. Among the inorganic plasma components, calcium was significantly decreased following copper exposure. Conversely, organic plasma components such as glucose and total protein were significantly increased. Similarly, enzymatic components, such as aspartate transaminase, alanine transaminase, and alkaline phosphatase, were also significantly increased. These findings suggest that the copper exposure is detrimental to the survival rates and physiology of C. carpio nudus.

Different herbs and spices have been used as feed additives for various purposes in poultry production. This study was conducted to assess the effect of feed supplemented with black pepper (Piper nigrum), turmeric powder (Curcuma longa), coriander seeds (Coriandrum sativum) and their combinations on the performance of broilers. A total of 210 (Cobb) one-d-old chicks were divided into seven groups of 30 birds each. The treatments were: a control group received no supplement, 0.5% black pepper (T1), 0.5% turmeric powder (T2), 2% coriander seeds (T3), a mixture of 0.5% black pepper and 0.5% turmeric powder (T4), a mixture of 0.5% black pepper and 2% coriander seed (T5), and a mixture of 0.5% black pepper, 0.5% turmeric powder and 2% coriander seeds (T6). Higher significant values of body weight gain during the whole period of 5 weeks (p<0.001) were observed in broilers on T1, T3, T5, and T6 compared to control. Dietary supplements with T1, T2, T3, and T6 improved the cumulative G:F of broilers during the whole period of 5 weeks (p<0.001) compared with control. The dressing percentage and edible giblets were not influenced by dietary supplements, while higher values of relative weight of the liver (p<0.05) were obtained in T5 and T6 compared to control. The addition of feed supplements in T5 and T6 significantly increased serum total protein and decreased serum glucose, triglycerides and alkaline phosphatase concentrations compared with the control group (p<0.05). Broilers on T6 showed significant decrease in the serum glutamate pyruvate transaminase concentration (p<0.05) compared to control. The broilers having T5 and T6 supplemented feed had relatively greater antibody titre (p<0.001) at 35 d of age than control. It is concluded that dietary supplements with black pepper or coriander seeds or their combinations enhanced the performance and health status of broiler chickens.

We have previously shown that determination of glucose uptake using ${\alpha}$-methylglucose(${\alpha}$-MG) is very sensitive and rapid parameter for the assessment of loss of cellular fu nction in renal cell line($LLC-PK_1$). The present study was designed to elucidate the mechanism of inhibition of ${\alpha}$-MG uptake and the intracellular site of toxic action of cisplatin(CIS). $LLC-PK_1$ cells were exposed to various concentrations(5 ${\mu}$M-l00 ${\mu}$M) of CIS for 5 hrs or 24 hrs and ${\alpha}$-MG uptake was determined. Mitochondrial function was evaluated by measuring intracellular ATP content and MTT reduction. The activities of marker enzymes for the basolateral membrane(Na$^+$-K$^+$ ATPase) and brush border membrane (alkaline phosphatase: ALP) were also measured. CIS treatment significantly inhibited the ${\alpha}$-MG uptake in a time- and dose-dependent manner above 25 ${\mu}$M for 5 hrs. Intracellular ATP content and MTT reduction were affected by 24 hr-treatment of 50 ${\mu}$M CIS. The activities of Na$^+$-K$^+$ ATPase and ALP were significantly decreased at 10 ${\mu}$M and 5 ${\mu}$M of CIS for 24 hrs, respectively. The incubation with CIS for 5 hrs had no effects on the intracellular ATP content, MTT reduction and the activities of marker enzymes up to 100 ${\mu}$M. These results partly indicate that inhibition of ${\alpha}$-MG uptake by CIS may not be attributed to the disturbance of mitochondrial function or inhibition of the activity of Na$^+$-K$^+$ ATPase and can be resulted from direct effect of CIS on the Na$^+$/glucose cotransporter in brush border membrane. This study shows that additional mechanistic information, indicating the intracellular site of nephrotoxic action, can be gained by coupling the ${\alpha}$-MG uptake and ATP content or the activity of Na$^+$-K$^+$ ATPase.

The present study was carried out to investigate the potential adverse effects of 1,3-dichloro-2-propanol on pregnant dams after maternal exposure during the gestational days (GD) 6 through 19 in Sprague-Dawley rats. The tested chemical was administered orally to pregnant rats at dose levels of 0, 10, 30, or 90 mg/kg/day. During the test period, clinical signs, mortality, body weights, food consumption, serum biochemistry, gross findings, organ weights, and Caesarean section findings were examined. In the 90 mg/kg group, decreases in the body weight gain and food consumption, and increases in the weights of liver and adrenal glands were observed. Serum biochemical investigations revealed increases in aspartate aminotransferase (AST), alanine aminotransferase (ALT), cholesterol (CHO), triglyceride (TG), alkaline phosphatase (ALP), and bilirubin (BIL) and decreases in glucose (GLU), albumin (ALB) and total protein (TP). In the 30 mg/kg group, a decrease in the food consumption and an increase in the liver weight were observed. Serum biochemical investigation also showed increases in CHO and TG and a decrease in glucose. Since there were no signs of maternal toxicity in the 10 mg/kg group, it is considered to be the no-observed-adverse-effect level (NOAEL) of 1,3-dichloro-2-propanol. It is concluded that successive oral administration of 1,3-dichloro- 2-propanol to pregnant rats for 14 days may cause significant toxicities in body weight and liver at a dose rate ${\geq}$ 30 mg/kg/day.

Hybrid grouper (Epinephelus fuscoguttatus ♀×E. lanceolatus ♂) (mean weight 27.3±3.8 g, mean length 11.6±0.7 cm) were exposed to waterborne nitrite at 0, 100, 200, 400, 800, and 1600mg L^-1 for 96 hours. The hematocrit and hemoglobin values were significantly decreased by exposure to 100 mg L^-1 and 400 mg L^-1, respectively. In plasma components, no significant change was observed in magnesium. Glucose was significantly increased by 200 and 400 mg L^-1 nitrite but reduced by 800 mg L^-1. Cholesterol was significantly decreased by 400 mg L^-1 nitrite, but there was no significant change in total protein. GPT(glutamic pyruvate transaminase) was significantly increased by exposure to 200 and 400mg L^-1. ALP(Alkaline phosphatase) was significantly increased by 800 mg L^-1. The results of this study indicate that acute exposure to nitrite changes physiological parameters, such as hematological properties and plasma components.

A series of experiment was conducted to determine the concentrations of progesterone and estradiol and metabolite contents in the serum of 26 Korean native cows raised at Alpine Experiment Station during the period of late pregnancy. Blood samples were collected by jugular puncture from individual cow at 5 day intervals from 30 days prepartum to 5 days prepartum and daily collected from 5 days prepartum to the day of parturition. Progesterone and estradiol concentrations in the serum were analyzed by Radioimmunoassay (R.I.A) method and serum metabolite contents were analyzed by autoanalzer MT II system. The following are summary of the results obtained: 1. Progresterone concentrations during the late preganacy were maintained at high level (5.12-11.70ng/$m\ell$) from 30 days prepartum to 8 days prepartum and fell rapidly from 5.12$\pm$1.07ng/$m\ell$ at 2 dyas prepartum to 1.48$\pm$0.32ng/$m\ell$ at 24 hrs prepartum. 2. Estradiol levles during the late pregancy increased gradually from 33.76$\pm$13.64pg/$m\ell$ at 30 days prepartum to 92.15$\pm$11.91pg/$m\ell$ at 11-15 days prepartum and increased thereafter sharply to a ranges of 161.76-238.4pg/$m\ell$ and were maintained at this increased levle until 24 hrs prepartum and decreased to 91.40pg/$m\ell$ at the parturition. 3. The correlation coefficients were found to be 0.2440 for cholesterol-progesterone relationship and -0.2552 for cholesterol-estradiol relationship, but there were statistically insignificant. 4. The changes in total protein contents during the late pregnancy were similar patterns to those of globulin and were maintained at high level only from 15 days to 5 days prepartum. 5. Glutamic oxaloacetate transaminase (GOT) levels were increased from 59.80$\pm$3.56u/$\ell$ at 90 days prepartum to 93.32$\pm$7.27u/$\ell$ at the day of parturition, but alkaline phosphatase levels were remained steady. 6. The levels of blood urea nitrogen, glucose and calcium remained almost constant during the late pregnancy. However, glucose concentration increased around the time of parturition.

We investigated the effect of tea fungus/kombucha beverage(TF) on the body weights, the blood glucose levels, lipid and protein concentrations, and enzyme activities in diabetic female rats. Sprague-Dawley rats were fed drinking water supplemented with 20% or 40% TF groups, respectively for 7 weeks. The female rats (mean weight 155.5$\pm$9.3 g) were assigned to one control and three diabetic groups. Diabetic groups were divided into diabetic control (TF free water), 20% or 40% TFD groups (20% or 40% TF in water) according to the levels of TF supplementation. Diabetes was experimentally induced by intraperitonially administration of streptozotocin in citrate buffer(pH 4.3) after 2 weeks feeding of four experimental water. Animals were sacrificed at the 5 weeks of diabetic state. The diabetic groups showed significantly decrease of body weight(6.8-7.5 g) compared with the control group(48.3 g). The hepatic, kidney and pancreatic weights of 20% or 40% TFD groups were not significantly different with D-control group. The fasting serum glucose level were higher in all diabetic groups than that of the control group. The concentrations of serum triglyceride in 40% TFD group and serum LDL-cholesterol in 20% TFD group were significantly decreased compared with the D-control group. The concentrations of serum total cholesterol and HDL-cholesterol, HDL-cholesterol/total cholesterol ratio, and atherogenic index in 20% or 40% TFD groups were similar to those in D-control group. The concentrations of hepatic triglyceride in 20% or 40% TFD groups were significantly decreased compared with the D-control group, but the concentrations of hepatic cholesterol and phospholipid were similar to all diabetic groups. The concentrations of serum and hepatic total protein, serum albumin, and the activities of GOT, GPT and LDH in the serum were the same levels of all diabetic groups.

Korean goral (Neamorhedus caudatus) is registered as a natural monument number 217 by South Korea Cultural Heritage Administration. It is also recognized as the endangered species I by Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). In this study, blood samples of Korean goral were collected to make reference intervals. Blood sampling was conducted on 19 numbers of Korean gorals (ten females, nine males), which were reared in Korean Goral Restoration Center. For total samples, the reference intervals of hematological parameters were: white blood cell $7.69{\sim}10.87K/{\mu}{\Lambda}$; hematocrit 36.73~46.18%; red blood cell $10.72{\sim}12.86K/{\mu}{\Lambda}$; hemoglobin 12.79~15.14 g/dL; mean corpuscular volume 33.15~36.75 fL; mean corpuscular hemoglobin 11.53~12.23 pg; mean corpuscular hemoglobin concentration 32.64-35.91 g/dL and red blood cell distribution width 39.2~43.46%. For total samples of each parameters, the following results were obtained for serum biochemistry: glucose 111.81~153.77 mg/dL; blood urea nitrogen 22.35~28.91 mg/dL; creatine 1.22~1.84 mg/dL; phosphate 4.57~6 mg/dL; calcium 8.7~9.1 mg/dL; total protein 6.53~6.92 g/dL; albumin 3.1~3.48 g/dL; globulin 3.26~3.62 g/dL; alanine aminotransferase 56.7~158.56 U/L; aspartate aminotransferase 230.35~473.06 U/L; alkaline phosphatase 178.06~332.47 U/L; gamma-glutamyl transpeptidase 131.6-~181.24 U/L; total bilirubin 1.47~2.12 mg/dL; cholesterol 46.48~71.52 mg/dL; amylase 16.3~26.03 U/L; sodium 150.43~153.88 mmol/L; potassium 3.98~4.6 mmol/L and chlorine 109.48~113.26 mmol/L. The ranges of values were similar campared to previous studies except in the case of RDW value, which showed higher range than the RDW value of a previous study. The reference intervals from this study will be useful data for treatment and management of gorals.
