A 2 years old female beagle dog was examined because of the vaginal discharge and vaginal swelling at 7th day after mating. Abdominal ultrasonography revealed multiple follicular cysts on both ovaries. Also, the ratio of superficial cells was above 90% based on vaginal cytology. She was still in standing heat, with the tail deflected up and flagging when a male sniffed the vulva and attempted to mount. The dog was diagnosed with multiple follicular cysts by vaginal cytology, clinical signs and ultrasonography. The dog was treated with GnRH $50{\mu}g$ injection by intramuscularly. The sizes of the cysts were decreased two weeks after GnRH treatment, and then the dog delivered an offspring at 68th day after last mating. To confirm the stage of estrous cycle, we performed hormone analyses, retrospectively $Estradiol-17{\beta}$ concentration was 78pg/ml at diagnosis. Progesterone concentration was 6.9ng/ml at the last mating, and 66.9ng/ml at diagnosis. Therefore, we confirmed that follicular cysts was observed during diestrous stage in a beagle dog.
Ketosis has become a very common and important metabolic disorder that causes substantial economic loss in modern dairy herds. We determined the risk factors for ketosis and associations with some blood metabolite concentrations in dairy cows. Blood from 475 Holstein cows on four dairy farms was collected weekly until 4 weeks after calving to measure blood ${\beta}$-hydroxybutyrate (BHBA) concentrations using electronic handheld meters. Cows were grouped based on the BHBA concentration into two groups: a ketosis group (${\geq}1.2mmol/L$, n = 150) and a non-ketosis group (< 1.2 mmol/L, n = 325). Peripartum health status (dystocia, retained placenta, and metritis), cow parity, and calving season were recorded to identify the risk factors for ketosis. Serum albumin, total cholesterol (TCH), and haptoglobin concentrations were compared between sub-groups of cows selected from the ketosis (n = 92) and non-ketosis (n = 50) groups 1 week postpartum ($7.5{\pm}0.2days$). The farm influenced the incidence of ketosis (P < 0.05). Cows calved during summer tended to have a higher risk (odds ratio [OR]: 1.61, P < 0.1) of ketosis than cows calved during spring. Cows with parities of two (OR: 1.95, P < 0.05) and three or higher (OR: 2.55, P < 0.01) were at higher risk than primiparous cows. Cows with metritis had a higher risk (OR: 7.02, P < 0.0001) of ketosis than cows without metritis. Serum albumin and TCH concentrations were lower (P < 0.01) in the ketosis group than in the non-ketosis group, whereas haptoglobin concentration was higher (P < 0.05) in the ketosis group than in the non-ketosis group. In conclusion, our results indicate that farm, summer calving, parity greater than one, and postpartum disease (metritis) were risk factors for ketosis. In addition, lower serum albumin and TCH concentrations and higher haptoglobin concentration were also associated with the incidence of ketosis in dairy cows.

Background: Plasminogen activator inhibitor type 1 (PAI-1), an important regulator of plasminogen activator system which controls degradation of extracellular membrane and progression of tumor cells, and PAI-1 gene polymorphic variants have been known as the prognostic biomarkers of non-small cell lung cancer patients. Recently, experimental in vitro study revealed that transforming growth factor-${\beta}1$ initiated PAI-1 transcription through epithelial growth factor receptor (EGFR) signaling pathway. However, there is little clinical evidence on the association between PAI-1 A15T gene polymorphism and prognosis of Korean population with pulmonary adenocarcinoma and the influence of activating mutation of EGFR kinase domain. Methods: We retrospectively reviewed the medical records of 171 patients who were diagnosed with pulmonary adenocarcinoma and undergone EGFR mutation analysis from 1995 through 2009. Results: In all patients with pulmonary adenocarcinoma, there was no significant association between PAI-1 A15T polymorphic variants and prognosis for overall survival. However, further subgroup analysis showed that the group with AG/AA genotype had a shorter 3-year survival time than the group with GG genotype in patients with EGFR mutant-type pulmonary adenocarcinoma (mean survival time, 24.9 months vs. 32.5 months, respectively; p=0.015). In multivariate analysis of 3-year survival for patients with pulmonary adenocarcinoma harboring mutant-type EGFR, the AG/AA genotype carriers had poorer prognosis than the GG genotype carriers (hazard ratio, 7.729; 95% confidence interval, 1.414-42.250; p=0.018). Conclusion: According to our study of Korean population with pulmonary adenocarcinoma, AG/AA genotype of PAI-1 A15T would be a significant predictor of poor short-term survival in patients with pulmonary adenocarcinoma harboring mutant-type EGFR.

Background: Patients with acute respiratory failure secondary to tuberculous destroyed lung (TDL) have a poor prognosis. The aim of the present retrospective study was to develop a mortality prediction model for TDL patients who require mechanical ventilation. Methods: Data from consecutive TDL patients who had received mechanical ventilation at a single university-affiliated tertiary care hospital in Korea were reviewed. Binary logistic regression was used to identify factors predicting intensive care unit (ICU) mortality. A TDL on mechanical Ventilation (TDL-Vent) score was calculated by assigning points to variables according to ${\beta}$ coefficient values. Results: Data from 125 patients were reviewed. A total of 36 patients (29%) died during ICU admission. On the basis of multivariate analysis, the following factors were included in the TDL-Vent score: age ${\geq}65$ years, vasopressor use, and arterial partial pressure of oxygen/fraction of inspired oxygen ratio <180. In a second regression model, a modified score was then calculated by adding brain natriuretic peptide. For TDL-Vent scores 0 to 3, the 60-day mortality rates were 11%, 27%, 30%, and 77%, respectively (p<0.001). For modified TDL-Vent scores 0 to ${\geq}3$, the 60-day mortality rates were 0%, 21%, 33%, and 57%, respectively (p=0.001). For both the TDL-Vent score and the modified TDL-Vent score, the areas under the receiver operating characteristic curve were larger than that of other illness severity scores. Conclusion: The TDL-Vent model identifies TDL patients on mechanical ventilation with a high risk of mortality. Prospective validation studies in larger cohorts are now warranted.
One hundred and sixty Taiwan country chickens (d-old chicks) were randomly assigned into four groups with four replicates and equal sex. Basal diets were supplemented with 0, 0.5, 1 and 2% of Bazhen powder, a traditional Chinese herbal medicine complex. The study was conducted for 14 wks. Experimental results indicated that Bazhen supplement did not influence feed intake, body weight gain and feed:gain ratio. Compared with control group, the percentage of serum HDL (high-density lipoprotein) linearly increased (p<0.03) and that of VLDL+LDL (very low-density+low-density lipoprotein) linearly decreased (p<0.03) in Bazhen supplemented groups, that 2% Bazhen was significantly different with control group (p<0.05). Chickens fed diets containing 2% Bazhen displayed reduced (p<0.05) serum GOT (glutamic-oxaloacetic transaminase) levels. The IgG, ${\gamma}$-globulin levels and PHA (phytohemagglutinin) skin challenge results in 1% Bazhan supplemented group were higher (p<0.05) than in the control group, the SRBC (sheep red blood cell) and ND (newcastle disease) titers in Bazhen supplemented groups were linear higher (p<0.05) than in the control group. The liver catalase activity and the capacity of scavenging DPPH (${\alpha}$-${\alpha}$-diphenyl-${\beta}$-picrylhydrazyl) radical were linearly increased (p<0.03) in Bazhen supplemented groups, and the 1 and 2% groups were different from the control group (p<0.05). Liver TBARS (thiobarbituric acid-reactive substances) levels in all Bazhen supplemented groups and total glutathione level in the 2% group were reduced (p<0.05) compared to the control group and displayed a linear response (p<0.05). The TBA (thiobarbituric acid) and pH value of the breast muscle after 24 h post-mortem in the Bazhen supplemented groups was linear lower (p<0.05) than in the control group. Results from this study demonstrated that Bazhen supplement in chicken had several beneficial effects, including increased SRBC and ND titers, HDL and IgG, ${\gamma}$-globulin levels, PHA skin challenge result, decreased VLDL+LDL and GOT levels, and displayed antioxidation effects in serum and carcass meat parameters.
Based on genome-wide association studies (GWAS) a linkage between several variants such as single nucleotide polymorphisms (SNPs) in intron 3 of SMAD7 (mothers against decapentaplegic homolog7) were, rs12953717, rs4464148 and rs4939827 has been noted for susceptibility to colorectal cancer (CRC). In this study we investigated the relationship of rs12953717 and rs4464148 with risk of CRC among 487 Iranian individuals based on a case-control study. Genotyping of SNPs was performed by PCR-RFLP and for confirming the outcomes, 10% of genotyping cases were sequenced with RFLP. Comparing the case and control group, we have found significant association between the rs4464148 SNP and lower risk of CRC. The AG genotype showed decreased risk with and odds ratio of 0.635 (adjusted OR=0.635, 95% CI: 0.417-0.967, p=0.034). There was no significant difference in the distribution of SMAD7 gene rs12953717 TT genotype between two groups of the population evaluated (adjusted OR=1.604, 95% CI: 0.978-2.633, p=0.061). On the other hand, rs12953717 T allele showed a statistically significant association with CRC risk (adjusted OR=1.339, 95% CI: 1.017-1.764, p=0.037). In conclusion, we found a significant association between CRC risk and the rs4464148 AG genotype. Furthermore, the rs12953717 T allele may act as a risk factor. This association may be caused by alternative splicing of pre mRNA. Although we observed a strong association with rs4464148 GG genotype in affected women, we did not detect the same association in CRC male patients.
Two feeding experiments were conducted to investigate the effects of dietary paprika (DP) and lipid (DL) levels on growth performance and skin pigmentation of pale chub, Zacco platypus. Six diets (designated as $P_0L_8,\;P_0L_{17},\;P_8L_8,\;P_8L_{17},\;P_{16}L_8\;and\;P_{16}L_{17}$) were formulated to contain 0%, 8% and 16% paprika with 8% and 17% lipid, respectively. For the growth experiment (Exp I), three replicate groups of fish (average weight 2.6${\pm}$0.2 g) were fed one of the six experimental diets for 8 weeks. At the end of the feeding period, survival was above 94% and not significantly different among dietary treatments. Weight gain, feed efficiency and protein efficiency ratio of fish fed the $P_{16}L_8$ diet were lower than for fish fed the $P_0L_8$ diet. The highest total carotenoid (TC) content was observed in fish fed the $P_{16}L_8$ diet. For the pigmentation experiment (Exp II), each experimental diet was fed to two replicate groups of fish (average weight 9.0${\pm}$0.5 g) for 8 weeks. At the end of the feeding period, TC content of the skin was significantly affected by DP (p<0.05). The highest TC content of the skin was observed after 6 weeks of feeding at all dietary treatments. Astaxanthin content of the skin was not affected by DP and DL (p>0.05). The capxanthin and zeaxanthin contents of skin increased significantly with increasing DP, whereas the opposite trend was observed for lutein and ${\beta}$-cryptoxanthin contents. The skin lightness ($L^*$ values) significantly decreased whereas the values of $a^*$ and $b^*$ were significantly increased in fish fed the diets containing paprika (p<0.05). The present results suggest that feeding a diet containing 8% paprika and 8% lipid for 6 weeks could improve skin pigmentation of pale chub without any adverse effects on growth performance.

Objectives : The purpose of this study was to investigate the effect of LR3 and SP6 acupuncture on liver damage of streptozotocin-induced diabetic mice. Methods : Male ICR mice were divided into four groups, consisting of the normal mice group(N), acupuncture-free diabetic mice group(Con), LR3-acupuncture diabetic mice group(LR3) and SP6-acupuncture diabetic mice group(SP6). The following measurements were taken: Body weight, food intake and water intake for 2 weeks; liver weight, and glucose levels in the serum and liver; ALT and AST in the serum; reactive oxygen species(ROS), reduced glutathione(GSH) and oxidized glutathione(GSSG) in the liver; and lastly, receptor for advanced glycation endproducts( RAGE), $N{\varepsilon}-carboxymethyl$ lysine(CML), $N{\varepsilon}-carboxyethyl$ lysine(CEL), phosphorylation of inhibitory kappa B alpha($p-I{\kappa}B{\alpha}$), nuclear factor-kappa B($NF-{\kappa}B$), activator protein-1(AP-1), cyclooxygenase-2(COX-2), inducible nitric oxide synthase(iNOS), tumor necrosis factor-alpha($TNF-{\alpha}$), ${\beta}-actin$, cytochrome c and caspase in the liver. Results : The liver weight and GSH/GSSG ratio were significantly increased in SP6 compared to Con. The glucose levels in the liver were significantly decreased in LR3 compared to Con. The generation of ROS and GSSG were significantly decreased in SP6 compared to Con. The expressions of RAGE, CML, AP-1, $TNF-{\alpha}$, cytochrome c and caspase 3 were significantly decreased in LR3 compared to Con. The expressions of $p-I{\kappa}B{\alpha}$, $NF-{\kappa}B$, AP-1, COX-2, iNOS and caspase 3 were significantly decreased in SP6 compared to Con. Conclusion : It is predicted that LR3 acupuncture is related to reduced glucose levels in the liver and expressions of AGE, and that, SP6 acupuncture is related to reduced oxidative stress-related transcription factors and inflammation-related proteins. Therefore, we suggest that LR3 and SP6 acupuncture have protective effects on the liver of streptozotocin-induced diabetic mice by preventing apoptosis.

This study has been focused on improving transformation efficiency of rice using Agrobacterium tumefaciens. We have demonstrated the effect of this system when the GPAT gene related to the cold-resistance was transferred by Agrobacterium tumefaciens in rice. Transformation conditions were modified using intron $\beta$-glucuronidase (GUS) expression as a reporter gene in the rice. In this study, mature seed-derived calli of rice (Oruza sativa L. cv. Dongjin) were pre-cultured for 3 days and then infected with Agrobacterium. When this infected calli were cultured in the dark for 10 days on co-cu]lure medium containing 50 mg/L of CaCl$_2$, 30 mg/L of acetosyringone, 2 mg/L of 2,4-D, 120 mg/L of betaine, high GUS expression was observed. In the present transformation system, the efficiency of transformation of GPAT gene was about 54%. Stable integration of GPAT gene into chromosomal DNA was proven by southern blot analysis of genomic DNA isolated from T$_{0}$ progenies. The progenies (T1 generation) derived from primary transformant of 5 lines were segregated with a 3 (resistant) : 1 (sensitive ratio) in medium containing hygromycin. This high frequency transformation system can be used as a useful tool in transformation of another monocotyledon.n.
To increase the functional properties of black soybean, we prepared the Chungkukjang with black bean at $40^{\circ}C$ after its germination according to the time course. The black soybean was soaked for 3 hr and dried three times with 2 hr interval. The germination ratio reached 50% for 12 hr germination and 80% for 24 hr, respectively. The optimum temperature of the germination was $18^{\circ}C$. The general composition of the germinated black soybean were not different from the control black soybean. During germination and growth, protease activity decreased slightly, whereas glucoamylase activity increased. On the other hand, content of isoflavone was increased to two times when the germinated leaf was 20 mm length. Absolute amount of the isoflavone was about 260 ${\mu}g$/g. When we estimated the sensory test of the Dua-chungkukjang, the color and mucoid formation was not different from traditional chungkukjang but bad flavor was decreased compared to traditional chungkukjang. And the same result was detected in the Dua-chungkukjang soup.
