  • Objective: The aim of this study was to estimate (co) variance components and genetic parameters for categorical carcass traits using Bayesian inference via mixed linear and threshold animal models in Anglonubian goats. Methods: Data were obtained from Anglonubian goats reared in the Brazilian Mid-North region. The traits in study were body condition score, marbling in the rib eye, ribeye area, fat thickness of the sternum, hip height, leg perimeter, and body weight. The numerator relationship matrix contained information from 793 animals. The single- and two-trait analyses were performed to estimate (co) variance components and genetic parameters via linear and threshold animal models. For estimation of genetic parameters, chains with 2 and 4 million cycles were tested. An 1,000,000-cycle initial burn-in was considered with values taken every 250 cycles, in a total of 4,000 samples. Convergence was monitored by Geweke criteria and Monte Carlo error chain. Results: Threshold model best fits categorical data since it is more efficient to detect genetic variability. In two-trait analysis the contribution of the increase in information and the correlations between traits contributed to increase the estimated values for (co) variance components and heritability, in comparison to single-trait analysis. Heritability estimates for the study traits were from low to moderate magnitude. Conclusion: Direct selection of the continuous distribution of traits such as thickness sternal fat and hip height allows obtaining the indirect selection for marbling of ribeye.

  • Random amplified polymorphic DNA (RAPD) analysis was used to detect the genetic diversity of soybean (Glycine max (L.) Merr.) varieties and field bean (Glycine soza Sieb. and Zucc.) Five soybean varieties and one field bean were analysed with random primers using the polymerase chain reaction (PCR). Nine primers of a total twenty random primer were selected to amplify DNA segments. A total of 74 PCR products were amplified and 67.6% of which were polymorphic. The size of DNA molecule is ranged 0.13~2.0Kb and typically generated four to eight major bands. Specific genetic marker were revealed in primer sequence 5'-CAG GCC CIT C-3', 5'-TGC TCT GCC C-3' and 5'-GTC CAC ACG G-3', respectively. Genetic similarity between each of the varieties were calculated from the pair-wise comparisons of amplification products and a dendrogram was constructed by an unweighted pair-group method with arithmethical means (UPGMA). The results indicate that intervarietal relationships of soybean have a narrow genetic base and between the varieties, Hwanggum-kong and Seckryang-bootkong is more closely related than the rest of varieties, and field bean is related quite distant.

  • This study was conducted to measure the central corneal thickness(CTT) changes associated with kinds of wearing contact lens. The CCT was measured using ultrasonic pachymeter in three hundred four subjects in their 20s and 30s. Although the CCT of Group 1 who had never worn any kinds of contact lens had no differences between left and right eye as well as between genders, the CCT tended to become thinner depending on the increment in refractive error. In Group 2 wearing only soft contact lens, the CCT was thinner depending on wearing period, and subjects wearing for more than 10 years had significantly thin CCT comparing with subjects wearing for less than 4 years. There was no significant difference in the CCT between Group 3 wearing only RGP lens and Group 2 for less than 4 years. Furthermore, when comparing the CCT between the Group 2 and Group 4 changing to RGP lens after wearing soft contact lens, there was no statistically significant change in the CCT. However, the CCT was significantly thinner in Group 5 changing to soft contact lens after wearing PMMA(polymethyl methacrylate) hard lens compared with Group 2.

  • Mutation in HNF1B, the hepatocyte nuclear factor-$1{\beta}$ (HNF-$1{\beta}$) gene, results in maturity-onset diabetes of the young (MODY) 5, which is characterized by gradual impairment of insulin secretion. However, the functional role of HNF-$1{\beta}$ in insulin secretion and glucose metabolism is not fully understood. We identified a family with early-onset diabetes that fulfilled the criteria of MODY. Sanger sequencing revealed that a heterozygous P159L (CCT to CTT in codon 159 in the DNA-binding domain) mutation in HNF1B was segregated according to the affected status. To investigate the functional consequences of this HNF1B mutation, we generated a P159L HNF1B construct. The wild-type and mutant HNF1B constructs were transfected into COS-7 cells in the presence of the promoter sequence of human glucose transporter type 2 (GLUT2). The luciferase reporter assay revealed that P159L HNF1B had decreased transcriptional activity compared to wild-type (p < 0.05). Electrophoretic mobility shift assay showed reduced DNA binding activity of P159L HNF1B. In the MIN6 pancreatic ${\beta}$-cell line, overexpression of the P159L mutant was significantly associated with decreased mRNA levels of GLUT2 compared to wild-type (p < 0.05). However, INS expression was not different between the wild-type and mutant HNF1B constructs. These findings suggests that the impaired insulin secretion in this family with the P159L HNF1B mutation may be related to altered GLUT2 expression in ${\beta}$-cells rather than decreased insulin gene expression. In conclusion, we have identified a Korean family with an HNF1B mutation and characterized its effect on the pathogenesis of diabetes.

  • A new PCR method was developed to detect Pectobacterium carotovorum which is the causative agent of soft rot in Brassica pekinensis. A specific detection primer set based on Lytic murein transglycolase gene was designed and evaluated. Using ERB3_F (5'-TGC GAC ACC TCC TCA TCA CG-3') and ERB3_R (5'-CTT ATC ACG CTG TAA CCA GC-3') primers, 437 nucleotides long fragment was specifically amplified. The amplified products were observed in 52 out of 55 strains of P. carotovorum or Pectobacterium carotovorum subsp. carotovorum. On the other hand, no amplification was observed in 8 organisms including Chinese cabbage and potato. The optimal PCR condition for the ERB3_F/ERB3_R primer set was $58^{\circ}C$ for annealing and 15 mM for $MgCl_2$. With serially diluted templates, the specific PCR sensitivitie limit was $2\times10^3$ copies. Also, this method can be applied not only to DNA but also to field samples. This PCR method may be expected to be useful for specific detection of P. carotovorum.

  • Diseased eel (Anguilla bicolor) displayed severe hemorrhages in the gills, and congestion and swelling in the liver. During the epizootic, the water temperature was $28^{\circ}C$ and the morality rates were about 5%. No parasites were found on the gills and skin. Bacteria were not cultured from any internal organs using TSA or SS agar at $28^{\circ}C$ for 48 hrs. Histopathologically, the gills showed epithelial hyperplasia in the base of secondary gill lamellae and hemorrhages in the capillaries. Some cells in the proliferated interlamellar epithelia exhibited marginal hyperchromatosis. And severe vacuolated changes in the parenchymal cells and congestion in the central veins were observed in the liver. The specific amplicon (396 bp) was detected from gills and opercula of affected eel PCR using Anguillid herpesvirus-1 (AngHV-1) -specific primer sets HVAPOLVPSD (5-'GTG TCG GGC TTT GTG GTG C-3') and HVAPOLOOSN (5'-CAT GCC GGG AGT CTT TTT GAT-3'). Sequencing analysis of the amplicon demonstrated that this gene was 99% homologous to the AngHV-1 sequence deposited in GenBank. This is the first report of AngHV-1 outbreak in the farmed shortfin eels (A. bicolor) in Korea. When diseased fish were maintained for 10 days at water temperatures of $32^{\circ}C$ and $35^{\circ}C$, the cumulative mortalities were 100% and 10%, respectively. Even though the AngHV-1 genome in the gills from the eel kept at $35^{\circ}C$ was detected using PCR, the structure of gill filaments was similar with that of normal fish. Increasing the water temperature to $35^{\circ}C$ was an effective way to diminish the mortality of AngHV-1 affected eel.

  • The object of this study is to measure the transit time and passage rate of capsule endoscopy (CE) in the gastrointestinal tract in medium sized beagle dogs ($7{\sim}13\;kg$). Animals were divided into four groups: only capsule (group 1, n=10), capsule+water (group 2, n=10), mettoclopramide+capsule (group 3, n=10), metoclopramide +capsule+water (group 4, n=10). The capsule transit times through the stomach and small bowel were evaluated by radiography findings. Gastric transit time (GTT), small intestinal transit time (SITT) and complete passage rate were measured in four groups. GTT's for each group were as follows; $45{\pm}20\;min$ (group 1), $117{\pm}35\;min$ (group 2), $150{\pm}40\;min$ (group 3), and $154{\pm}65\;min$ (group 4), while SITT's were $75{\pm}20\;min$ (group 1), $195{\pm}55\;min$ (group 2), $70{\pm}15\;min$ (group 3), and $76{\pm}15\;min$ (group 4). The complete passage rates were 20% (group 1), 40% (group 2), 20% (group 3), 50% (group 4). In all groups, if CE could pass through the pylorus, it passed all small intestinal tracts within 8 hours (battery life). Administration of water helped CE to pass pylori, except in case of metoclopramide administration. These results indicate that CE could be an useful tool for examining gastrointestinal diseases in the veterinary medicine.
