We applied the TD-OCT(Time-Domain Optical Coherence Tomography) system which utilized the reference by using the RSOD(Rapidly Scanning of Delayline) to the skin diagnosis (Arteriovenous rnalforrnationt.A VM)). We carried out an clinical experiment on the patient who has A VM with TD-OCT, Ultrasonography and Biopsy. As result of the experiment, OCT images of the skin showed the skin layers and the veins that not confirmed by Ultrasonography. By comparison with, we confirmed the analogous point.

This study was conducted to develop Korean native pig-specific DNA markers and analyze its relativity with meat quality using 30 of Korean native pigs and Landraces, respectively. To find species-specific DNA markers, we selected and tested a total of 60 microsatellite markers on the 4 and 7 chromosome using polymerase chain reaction (PCR). PCR amplification was carried out by microsatellite primer pairs labeled with fluorescent Fam, Hex and Ned. The fluorescent labeled PCR products were electrophoresed with Genetic Analyzer ABI 310 followed by the allelic and statistical analysis. According to the allelic frequency annalysis, of the 60 microsatellite markers 27 were preduced with a variety of genetic polymorphic alleles (p<0.05). Especially, alleles of SW1364, SW445, SW1369 and SWR773 microsatellite markers were identified to be species-specific markers between two breeds (p<0.01). To analyze the meat quality we determined the meat color, fat color, fat composition, cholesterol contents and hardness, and compared these characteristics with the alleles of 36 species-specific markers in all pigs. Of the 60 microsatellite markers 28 were found to be related with meat quality; 18 for meat and fat color, 7 for fatty acid, 4 for cholesterol contents and 10 for shear force and hardness. These selected markers will be useful in the genetic improvement of pigs for an excellent meat quality.
