A 1-year-old intact male Russian blue cat was admitted with a history of depression, partial anorexia, vomiting and dysuria. Through the blood analysis, ultrasonography and urinalysis, this cat was diagnosed as feline lower urinary tract disease with cystitis. Despite antibiotic therapy the cat showed stranguria and urinary catheterization were repeated several times. One week after, this patient appeared depression, hyperthermia and leukocytosis. Ultrasonography revealed a small amount of hypoechoic fluid around the right kidney and bacteria were found in the urine. The amount of the right subcapsular fluid was increased and bacteria were found in the fluid. On the excretory urography, leakage of contrast media were detected. The right kidney was surgically removed and suppurative fluid between the renal parenchyma and the thickened capsule was identified. After surgery, subcapsular abscess of the right kidney associated with pyelonephritis was confirmed histologically and this cat recovered without complications.

A 3 month old female baby, who had been diagnosed with right atrial isomerism associated with total anomalous pulmonary venous return (TAPVR), a functional single ventricle and major aortopulmonary collateral arteries (MAPCA), underwent left MAPCA unifocalization and left Blalock-Taussig shunt (3.5 mm) at 3 months of age. The post-operative course was complicated by pulmonary venous congestion, and the drainage site of the TAPVR was found to be stenotic on echocardiography. We performed sutureless repair of the TAPVR along with unifocalization of the right MAPCA. She was put on an extracorporeal membrane oxygenator for 8 days after the 2nd operation, and she was able to come off the oxygenator with the placement of a central shunt (3 mm). She developed tracheal stenosis, which was presumably due to longstanding endotracheal intubation, and she then underwent tracheostomy. She was discharged to home on day 104 after the 1st operation, and she has been followed up for 2 months in a good clinical condition.

To establish the differential diagnosis and treatment method in bovine ovarian cysts, specially ovarian cysts with corpus luteum, serum progesterone concentration, rectal palpation and ultrasonography for measuring the cystic wall thickness and diameter of cyst and corpus luteum were investigated from 1,188 dairy cows with ovarian cysts. The plasma progesterone concentrations were 0.3$\pm$0.4 (mean$\pm$SD) ng/ml in 629 cows with follicular cysts, 3.7$\pm$1.1 ng/ml in 431 cows with luteal cysts, and 3.8$\pm$1.2 ng/ml in 128 cows with coexist of ovarian cysts and corpus luteum, respectively. The cystic wall thickness by ultrasonography were 1.6$\pm$0.4 mm in 629 cows with follicular cysts, 4.2$\pm$1.5 mm in 431 cows with luteal cysts, and 1.6$\pm$0.6 mm in 128 cows with coexist of ovarian cysts and corpus luteum, respectively. The days from initial treatment to insemination in follicular cysts were 28.1$\pm$6.9 days in treatment of GnRH alone, 15.9$\pm$2.9 days in combination of GnRH and dinoprost, and 15.1$\pm$3.1 days in combination of GnRH and cloprostenol. The percentages of cows conceived within 100 days after initial treatment were 61 %, 68% and 73% in treatment of GnRH alone, combination of GnRH and dinoprost, and combination of GnRH and cloprostenol, respectively. The days from initial treatment to insemination in luteal cysts were 3.8$\pm$0.6 days in treatment of dinoprost alone and 3.8$\pm$0.7 in cloprostenol alone. The percentages of cows conceived within 100 days after initial treatment were 69.5% and 68.5% in treatment of dinoprost and cloprostenol, respectively. The days from initial treatment to insemination in coexist of cysts and corpus luteum were 3.7$\pm$0.7 days in treatment of dinoprost alone and 3.8$\pm$0.6 in cloprostenol alone. The percentages of cows conceived within 100 days after initial treatment were 87% and 84% in treatment of dinoprost and cloprostenol, respectively. These results suggest that the best choice for treatment agents in ovarian cysts were combination of GnRH and PGF$_2$$\alpha$ in follicular cysts, and the PGF$_2$$\alpha$ in luteal cysts and in coexist of cysts and corpus luteum, respectively. In conclusion, it is suggest that ultrasonography is useful diagnostic tool for diagnosis and selection of treatment remedy in cystic ovaries of bovine.

A seven-year-old, castrated male Basset hound weighing 21.1 kg was presented for investigation of anorexia, lethargy, weight loss, melena and vomiting for 4 months. In laboratory findings, microcytic hypochromic anemia was identified, and other results were within a normal reference range. On the plain radiographs, soft tissue opacity was increased in the descending duodenal region; and on the contrast radiographs, ulcerative changes were identified in the entire segment of descending duodenum. Ultrasonographic findings included increased duodenal wall thickness and duodenal wall layering was lost. Endoscopy revealed irregular mucosal surface and luminal narrowing of the descending duodenum. There was concentrically thickened descending duodenum on the computed tomography. And the wall of the descending duodenum showed heterogenous enhancement after contrast agent injection. On histopathological findings, both chronic inflammation with mucosal proliferation and neoplastic changes with multiple small glandslike structures invading into the submucosa were identified. Based on these findings, presented case was diagnosed as an annular form duodenal adenocarcinoma. After 13 months of supportive medical treatment, the patient was expired. The purpose of this case report was to describe the duodenal adenocarcinoma in a dog.

Hydrosyringomyelia is a dilation of the spinal cord central canal. In human it may be caused by congenital malformations such as Dandy-Walker syndrome and Chiari malformations or may be acquired as a result of infection, trauma or neoplasia. Hydrocephalus is an excessive accumulation of cerebrospinal fluid within the ventricles and occipital dysplasia is the dorsal extension of the foramen magnum. Hydrosyringomyelia and hydrocephalus can be confirmed by computed tomography or magnetic resonance imaging (MRI). A 3-year-old male maltese was presented with a history of long-term seizure. Blood examination was all unremarkable. On rostrodorsal-caudoventral oblique radiograph of the skull showed severe occipital dysplasia. On brain sonography through the persistent fontanelle, severe lateral ventriculomegaly was revealed. MRI examination revealed hydrocephalus and hydrosyringomyelia. Diuretic therapy didn't reduce clinical symptoms and surgical decompression was conducted. The dog responded well with ventriculo-peritoneal shunting. MRI is the most superior modality to diagnose hydrocephalus and hydrosyringomyelia, to plan therapy and to determine the prognosis.

Progesterone을 함유하고 있는 CIDR(Controlled Internal Drug Release)의 질내삽 입은 황체기를 인위적으로 연장시킬 수 있다. CIDR의 삽입이,삽입시 존재했던 우세난포 (dominant follicle)의 반응과 난포의 발육반응 그리고 2회 또는 3회의 난포주기를 가지고 있는 처려우에서 CIDR의 삽입기간동안 난포의 성장 및 발육에 어떠한 영향을 미치는가를 비교검 토하기 위하여 배란후 16일째의 처녀우 4마리에 7일동안 CIDR를 삽입하였다. CIDR의 삽입 은 발정의 발현을 억제시켰으며 그리고 발정주기의 길이를 정상 발정주기보다 유의성있게 연 장시켰다($26.3{\pm} 0.5 vs 20.8{\pm}$ 1.5일, p<0.05). CIDR의 삽입시 혈장 progesterone 농도는 $3.6{\pm}$ 2.7 ng/ml 이었으며, 17일과 23일 사이에는 2.1-4.4 ng/ml($3.6{\pm}1.2 ng/ml$) 사이를 유지했다. 혈 장 estradiol-179의 농도는 난포의 발육 및 배란전 배란난포의 성숙을 나타내는 특징적인 변화 양상을 나타래었다. 4마리의 처녀우중 2마리는 CIDR 삽입전 발정주기당 2회의 난포주기를 가진 반면, 나머지 2마리는 주기당 3회의 난포주기를 가졌다. 그렇지만 CIDR의 삽입기간동안 모든 처녀우는 주기당 3회의 발정주기를 가졌다. CIDR의 삽입전 발정주기당 3회의 난포주기 를 갖는 처녀우에서 CRR의 삽입은 세 번째 난포주기에서 배란성 우세난포의 우세기 (dominant phase)를 연장시켰다. 3회의 난포주기를 갖는 2마리에서 CIDR의 삽입후 배란난포 는 존속시간과 우세기가 유의성있게 연장되었다. CIDR의 삽입전 발정주기당 2회의 난포주기 를 갖는 다른 2마리의 처녀우에서 CIDR의 삽입후 우세난포는 곧바로 퇴행되었고 새로운 난 포주기를 형성하였으며, 우세난포의 우세기와 배란난포의 존속기간을 연장시키지 않았다. CRR의 삽입은 CIDR의 삽입후 이어지는 발정주기동안 난포의 발육 및 성장에 영향을 미치 지 않았으며 발정주기의 길이, 난포주기, 혈장 progesterone 및 estradiol-179 농도에 영향을 미치지 않았다. 결과적으로 황체기 후반부에 CIDR의 삽입은 CIDR삽입전 발정주기동안 3회 의 난포주기를 갖는 처녀우에서 배란성 우세난포의 발육과 배란까지의 기간을 연장시켰고 2회 난포주기를 갖는 처녀우에서는 우세난포를 곧바로 퇴행시킨후, 새로운 난포주기를 형성 하였다.

A 15 kg 6-year-old intact male Jindo dog with a history of a respiratory distress, hindlimb paralysis with necrosed skin of dorsal digit for three weeks was referred to Animal Medical Center, Chonbuk National University. Heartworm infection was identified by kit examination. In plain thoracic radiographs, dilated pulmonary arteries reverse D sign and focal interstitial pattern was compatible with heartworm infection and possible pulmonary thromboembolism. Abdominal radiographs showed poor serosal detail indicating fluid accumulation within peritoneal cavity. No evidence of musculoskeletal abnormalities was found. Ultrasonography presented focal wedge-shaped hyperechogenecity on the both poles of left kidney, weak or absent pulse on the distal to the external iliac artery as well as ascites and irregular liver margin. Multi-organ failure was strongly supposed by blood profile including leukocytosis, anemia, hemoglobinuria bililubinemia, hypoalbuminemia, imbalance of electrolytes, and increased hepatic and renal function values. Interestingly, the glucose level is remarkably lower in pelvic limb compared to thoracic limb. Suspected pulmonary thromboembolism, renal infarction and femoral arterial embolization causing hindlimb paralysis and dermatic necrosis were confirmed by 3D reconstructed CT imaging. Prior to taking a consideration of euthanasia, interventional radiology was experimentally attempted but failed due to not recovered from general anesthesia. Early and accurate diagnosis of thromboembolism is valuable and 3D reconstructed CT images might be very useful to show the correct way to treat effectively.

An 11-year-old intact female miniature poodle presented with a four-month history of hemorrhagic effusion. The patient was alert on physical examination, although muffled heart sounds were noted upon auscultation of the right hemithorax. The radiographic finding was pleural effusion. Ultrasonography revealed cystic changes in both ovaries and several nodules in the liver. A refractory opacity in the right lung field, as visualized with computer tomography (CT), was diagnosed as right middle lung lobe torsion with a collapsed bronchus. Five days after diagnosis, a right fifth intercostal thoracotomy was performed to remove the right middle lung lobe; the right middle lung lobe was grossly shrunken as a result of chronic lung lobe torsion. Ovariohysterectomy was also performed. Histopathologic examination revealed papillary adenocarcinoma in both ovaries and suspected metastasized ovarian adenocarcinoma cells in the lung lobe. The patient recovered favorably and had been doing well up to two months post-surgery. However, after four months, the dog presented with respiratory difficulty. The radiographic findings were pleural effusion and collapse of the right cranial and left caudal lung lobes. Malignant cells of epithelial origin were observed in the pleural effusion. The tumor cells were suspected to be metastasized cells from the previously resected lung lobe. Although cancer treatment was recommended, the suggestion was suspended and the dog was discharged from hospital. This was a case of lung lobe torsion that had occurred because of hemorrhagic effusion due to tumor. Although ovariohysterectomy and lobectomy were performed, there was a relapse of hemorrhagic effusion because of metastasized tumor from the previously resected lung lobe.

Cystinuria is an autosomal recessive disease characterized by impaired transport of cystine and dibasic amino acids in the proximal renal tubule, resulting in the formation of cystine stones. It is believed to account for about 1% of all kidney stones and up to 10% of pediatric stones. Here we report a case of cystinuria with multiple renal stones confirmed by genetic mutational analysis. An 8-month-old girl was admitted to AMC with persistent fever and multiple renal stones. A renal sonogram showed multiple stones at the right renal pelvis, right distal ureter, and left renal medullary portion. An approximately 1 cm renal stone was extracted spontaneously, and stone analysis revealed it to be composed entirely of cystine. Cystinuria was confirmed by increased urine dibasic amino acid levels, including cysteine, and genetic mutational analysis showed the patient to be a homozygote for the pathogenic c. 1820del (p.L607fs) of SLC3A1. Despite treatment with oral hydration and urinary alkalinization, and restricted intake of animal protein, the stones increased in size and number. The patient has since been treated with tiopronin.

This study was performed to investigate and measure the antimicrobial activity of evergreen woody species extracts on Trichophyton mentagrophytes. To do this, leaves and stems were collected from Wando and Jeju islands, and were used for the extraction with different solvents (i.e., distilled water, 80% ethanol, and 100% methanol), and at different ultrasonic extracting times (i.e., 15, 30, and 45 minutes). The experiment was conducted by using the agar diffusion method. The clear zone was measured after incubating the paper disc containing the plant extract in a bacterial culture medium. The controls were synthetic antimicrobials, methylparaben and phenoxyethanol, at concentrations of 0.4, 1, 2, and 4 mg/disc. Altogether, extracts of 56 out of 64 species used in this study had inhibitory activity, which confirmed their antimicrobial activity against Athlete's foot. Among them, the crude ethanolic extract of Elaeocarpus sylvestris in 45 min showed a zone of inhibition < 20.2 mm, while the clear zone of Actinodaphne lancifolia ethanolic extraction for 30 min was 23.5 mm. Also, Quercus acuta, Dendropanax morbiferus and Daphne odora showed clear zones of 28.0 mm (45 minutes ethanolic extraction), 20.5 mm (45 minutes crude methanolic extraction) and 19.7 mm (45 minutes methanolic extraction), respectively. Thus, these results confirm that the extracts of evergreen woody species have therapeutic potential against Athlete's foot, and suggest that in order to extract adequate amounts of antimicrobial substance from the plant sources, ideal extraction condition has to be considered.
