Experimental obstruction of urethra was induced for 66 hours on 5 male dogs to determine the diagnostic value of ECG and blood chemical values. The results obtained in the examination were summarized as follows ; 1. Changes of ECG, blood chemical values and clinical sings were observed from 30 hours after urethral obstruction. 2. In ECG, the peaked and amplitude of T wave were increased remarkably. p wave were decreased, and intervals of PR(Q) and QRS complex were prolonged after urethral obstruction. 3. The levels of BUN, potassium, creatinine in serum after urethral obstruction were increased remarkably and correlation between these levels and the increase of amplitude in T wave were recognized to be significant.

A dairy farm that has been suffered continuously(more than 2 years) from brucellosis in Korea in spite of repeated legal test-and-slaughter was investigated the main source of infection in the farm. All cattle(22 milking cows, 44 heifers, 60 calves, 8 bull), dogs(3 mixed breed), feces from wild birds(3 samples), drinking water(3 sites), and soil in the paddocks(14 sites) inside the farm were examined with serological and/or bacteriological methods including specific DNA detection with PCR method. Brucella spp in the milk and blood were detected in 12/22 and 5/22 milking cows, respectively, although all of them were negative with conventional tube agglutination test. The number of serologically positive heifer was 15(15/44), but the isolation of Brucella spp was succeeded in the only 11(11/15) of them. Brucella were detected in vagina 1(1/11) and nasal (3/12) excretion in serologically positive heifers. All the three dogs were serologically positive, and Brucella spp were isolated from their blood. However, Brucella spp were not detected in the drinking water, soil in the paddocks, nor the feces of wild birds. The results suggest that milking cow secrete Brucella spp through milk, genital tract and nasal cavity, which are the major source of infection in this farm, the main infection route of Brucella spp is contact to contact with Brucella spp excreting animals rather than environmental contamination. The animals, living together with infected cow such as dogs, are the readily susceptible and are required to be examined for Brucella spp.

The ELISA titers to avian pneumovirus(APV) and avian reovirus(ARV) were surveyed to sera of 38 breeder farms(78 blocks, 1,560 hens) in Jeonbuk province during February to October, 2005. In APV, the positive ELISA were detected 36(94.7%) breeders, 71(91.0%) blocks, 1,057(67.8%) hens, and their S/P ratio was 1.940. Regionally, the positivity of 24 breeders farms in the Jeonju, Jeongeup, Namwon, and Jangsu were noted as 100%, whereas 85.7% in Iksan. The positivity to species such as Cobb(20), Ross(13) and Hanhyup-3(5), all of the breeding farms were detected as positive, 40(86.9%), 17(94.4%) and 14(100.0%) in blocks, 553(60.1%), 285(79.2%) and 219(78.2%) in hens, and their mean S/P ratio were 1.677, 1.769 and 2.254, respectively. The positivity of the breeders vaccinated with ARV, all of the 9 breeder farms(38 blocks) were noted as 100%, but 627(82.5%) in hens, and its mean S/P ratio was 1.273. Whereas nonvaccinated with ARV were 28(96.5%) in breeders farms, 38(95.0%) in blocks, 660(82.5%) in hens, and the mean S/P ratio was 1.612. In species which were vaccinated with ARV, 11 breeder farms(38 blocks) were noted as 100%, but 82.5% in hens, and their mean S/P ratio were 1.315. Whereas in nonvaccinated with ARV, 25(92.6%) in farms, 38(95.0%) in blocks and 660(82.5%) in hens were positive, and their mean S/P ratio was 1.532.
