Two Maltese (2-year-old, intact female and 4-month-old, intact female) and a Pekingese (10-year-old, intact male) dogs were referred due to vomiting, anorexia, head-pressing and hypersalivation. Physical examinations, complete blood count, serum chemical analysis, radiography, ultrasonography and computed tomography (CT) were evaluated. Laboratory findings in these dogs included high hepatic enzyme, serum bile acid and ammonia concentration. Microhepatia was found on abdominal radiographs in two dogs. The existence of portosystemic shunt was presented in abdominal ultrasonography. The shunt vessel was identified in all dogs by CT imaging. Based on three-dimensional CT reconstruction, the origin and termination of each shunt vessel were defined certainly. In consequence, each dog was diagnosed single extrahepatic portosystemic shunt. After diagnosis, surgical treatment was performed in all dogs. This case report describes clinical finding, imaging characteristics, and three-dimensional CT imaging of single extrahepatic portosystemic shunt cases.

Autosomal-dominant polycystic kidney disease (AD-PKD) is common in Persian and Persian-related breeds, and is sporadically reported in Scottish Fold cats. A 5-year-old male Scottish Fold cat was diagnosed with polycystic kidney disease based on screening tests and abdominal ultrasonography and died 3.5 months after diagnosis. The cat had 14 kittens with three queens, including his female sibling, with an age range of 3 months to 8 years. Genetic testing to confirm the genetic transmission of AD-PKD which detects the mutated PKD1 gene was performed. Abdominal ultrasonography confirmed the presence of renal cysts. Nineteen cats were screened in the present study (13 males and 6 females), with an age range of 3 months to 8 years. The results of renal ultrasonography agreed with the genetic test results in the 19 cats in which both tests were performed and 8 cats were diagnosed as ADPKD based on these tests. AD-PKD has not been investigated in cats in South Korea. Moreover, this is the first report of AD-PKD in a family unit of Scottish Fold cats.

Paraplegia remains unresolved as the most dreaded operative complication with surgical treatment of descending thoracic and thoracoabdominal aortic diseases. In this study, the neuroprotective effect of trimetazidine that has been used clinically for ischemic heart disease was investigated in a rabbit spinal cord ischemia model. Material and Method: Thirty-three New Zealand white rabbits were randomized as follows: control group undergoing abdominal aortic occlusion but receiving no pharmacologic intervention(Group 1, n= 17); TMZ group(Group 2, n= 16) receiving 3 mg/kg trimetazidine intravenously before the occlusion of the aorta. Ischemia was induced by clamping the abdominal aorta just distal to the left renal artery for 30 minutes. Neurologic status was assessed at 2, 24, and 48 hours after the operation according to the modified Tarlov scale, then the lumbosacral spinal cord was processed for histopathologic examinations 48 hours after the final assessment. Result: The average motor function score was significantly higher in the TMZ group(3.20 $\pm$ 0.77 vs 1.13 $\pm$ 1.25 at 2 hours, 3.50 $\pm$ 0.76 vs 1.45 $\pm$ 1.57 at 24 hours, and 3.91 $\pm$ 0.30 vs 1.86 $\pm$ 1.86 at 48 hours after operation; p value$\leq$0.05). Histologic observations were correlated with the motor scores. Conclusion: The results suggested that trimetazidine reduced spinal cord injury during aortic clamping and that it may have clinical utility for the thoracoabdominal aortic surgery:

Purpose : The intestinal mucosal defect has been known as one of the pathogenicmechanisms of IgA nephropathy. Oral antigens usually induce the activation of Th2 cells and mast cells. These cells secrete cytokines IL-4, IL-5 and TGF-$\beta$, which increase IgA production. Although ketotifen (benzocycloheptathiophene) is an H1 antagonist and a mast cell membrane stabilizer, it could protect the gastrointestinal membrane through inhibiting the production of IL-4, IL-5, PGE2, and LTB4, and decreasing the activity of nitric oxide synthease. Therefore, we have investigated if ketotifen may protect the development of IgA nephropathy with an oral antigen. Methods : ICR mice were used as an animal model orally with Poliovax only [ketotifen (-)], the other group was given oral ketotifen [ketotifen (+)] in addition to Poliovax. Results : Mesangial IgA deposition developed in 11 out of the 18 mice in the ketotifen (-) group, while in three out of the nine mice in ketotifen (+) group. The mesangial change developed in 16 out of the 18 mice in the ketotifen (-) group, while in five out of the nine mice in the ketotifen (+) group. Serum IL-4 and IL-5 levels were not significantly lower in the latter group than in the former. Conclusion : According to the statistical results from the above, ketotifen therapy would be beneficial to reducing mesangial changes in IgA nephropathy.

Distribution and population of plant parasitc nematodes were investigated using 70 soil and root samples in total collected from six locations in Gyeongbug and Gyeongnam provinces. Among nematodes identified, Meloidogyne spp. was the most prevalent with $91.4\%$ in frequency cf detection. Frequency of detection was $87.1\%$ for Tylenchus sp., $24.3\%$ for Hirschmanniella, $23.3\%$ for Aphelenchus sp., and $20\%$ for Aphelenchoides sp.. Meloidogyne spp. was most abundant from samples collected in Namji and the number of nematodes dectected was 2,104 per $300cm^3$ soil. The number of Meloidogyne spp. detected was 671 from Milyang, 401 from Samrangjin. The number of nematodes was 57 from Samrangjin for Tylenchus sp., 127 from Gupo for Pratylenchus, 26 for Aphelenchoides sp. and 34 for Criconemoides from Samrangjin. Population of Meloidogyne spp. was the highest in Namji and Milyang where pepper and cucumber or pepper and chinese cabbage was cultivated in multiple croppings, however, population of Pratylenchus spp., and Meloidogyne spp. was the highest in Samrangjin where strawberry was cultivated as a single crop. Population in Pratylenchus and Meloidogyne was the highest in Gupo where tomato and chinese cabbage were cultivated alternatively, however, population of nematodes was generally low in Seongju and Yucheon where watermelon-rice or pepper-rice were cultivated in sequence. Meloidogyne spp. and Pratylenchus spp. appear to be economically important nematode species in cropping by controlled horticulture. In this study, 15 species of plant parasitic nematodes were identified.

The effect of natural enemies on four major pests of hot pepper was tested in greenhouses. The aphids were successfully controlled by introducing three Aphidius colemani-banker plants, and releasing 23.3 wasps per $m^2$ on April 16 and 23 wasps per $m^2$ in a greenhouse of 660 $m^2$. To control thrips, Orius laevigatus was released twice, 3.0 bugs per $m^2$ at a time(May $11^{th}$ and June $12^{th}$). The thrips population was controlled within 0.3 thrips per flower during the growing season. To control two species of mites, Tetranychus kanzawai and Polyphagotarsonemus latus, and the silverleaf whitefly, Bemisia tabaci, a total of 113.7 individuals of Amblyseius swirskii were released twice(May $11^{th}$ and $30^{th}$). The densities of B. tabaci and T. kanzawai were kept within 171.0 individuals/trap and 0.8 individual/leaf, respectively. P. latus was suppressed completely twelve days after release. The cost of the released natural enemies to control the four arthropod pests in this study was 420,000 Won per 660 $m^2$.

Cryptosporidium, a coccidian protozoa, commonly causes a self-limiting diarrheal illness in humans and animals. Fecal samples from various animals in Chonbuk district were observed using Sheather's aoatation technique, Kinyoun's modified acid-fast staining, and osmic acid pre-fixed Giemsa staining. The oocysts were detected in 74 cages(29.6%) out of 250 cages of mature mice, 26 (13.3%) out of 195 mature house rats, 75 (15.0%) out of 4-week-old 500 fowls, 98(19.9%) out of 6 to 8-month-old 500 pigs, and 111(22,2%) out of 2 to 5-year-old 500 dairy cattle, respectively. The degree of prevalence was slight in general, but actual prevalence was higher than infection rate because the detection rates were higher in repeated-preparation examinations in comparison to the first examination. Meanwhile, large and small types of oocysts were detected from mice, house rats, pigs, and cattle, and midium type from fowls.

The present study was performed to analyze the infection status of trematode metacercariae in fishes caught from Chunamchosuchi (pond) located in Uichang-gun. Kyongsangnam-do. A total of 130 freshwater fish of 5 species was collected by a fish net and fish traps from November, 1995 to May, 1996. They were examined under a stereomicroscope after artificial digestion with pepsin-HCI solution. A total of 8 species or metacercaria, i. e. Clonorchis sinensis, Echinochnsnw japonicas, Cvathocotwle orientalis, Diplostomun sp.. Metorchis orientalis. Holostephcnw nipponicw, Exorchis oviformis and unidentified echinostome, was detected from them. The metacercariae of C. sinenesis were found in 8/20 (40.0%) Accnthorhodeus Qsmwsi, 20/20 (100%) Cutter breuiccudc, 31/45 (68.9) Cultriculus eigenmanni and 21/25 (84.0%) Pseunorasborc pronga, and the average number of metacercariae detected in each fish species were 1.9, 31.7. I5.3, and 73.0. From the above results, it was confirmed that fresh-water fishes from Chunamchosuchi (pond) were highly infected with metacercariae of avian trematode, i.e. C. orientolis, H. nipponicus. M. oui,entnlis, E. jcponicw and Diplostonum sp., and 4 species of fish. P. parvc, C. breuiccudn, C. eigenmnnni and A. asmussi, were infected with metacaecariae of C. sinensis.

Five dogs diagnosed as apocrine gland adenocarcinoma (AGAC) of the anal sac based on cytology and/or histology. Mean age of these dogs was 11 years old. One dog treated with supportive care without other medical interventions for hypercalcemia was died one month after diagnosis. Other four dogs were treated with chemotherapy and one of these dogs was intervened with complete surgical resection. Two months after the diagnosis, one of the dogs treated with chemotherapy died. The survival time of other survived three dogs from the time of diagnosis was 19, 9, and 13 months respectively and they are still alive at this time. After chemotherapy, three dogs were managed generally in good body condition and maintained as similar in size as time of diagnosis. The results are suggested that it is worthwhile to try chemotherapy for managing AGAC in dogs especially complicated or metastasized to regional lymph nodes.
