An-11-year-old male Shih-tzu was admitted to emergency care unit of Haemaru Referral Animal Hospital with signs of dyspnea, anuria and depression. There were abnormalities on complete blood count and serum chemistry included leukocytosis with mild left shift, mild azotemia, and increased ALT activity. Fluid therapy(0.9% saline, 40 ml/hr) and antibiotics were immediately initiated. The patient began to vomit after 5 hours' rest and pale mucous membrane, bradycardia, and hypertension were noted. Abdominal ultrasonography revealed enlarged left adrenal gland and thrombus in caudal vena cava(CVC). Result of ACTH stimulation test was normal. Cytology of ultrasound-guided FNA smears showed numerous naked nuclei, which was suggestive of adrenal medullar tumor. Concentrations of 24 hour urine metanephrine and normetanephrine was moderately increased compared to those of a control dog. Adrenal mass was surgically removed, and biopsy of the CVC mass was obtained. After surgery the patient began to recover but the dog acutely developed cardiopulmonary arrest and died. On histopathology the adrenal mass and biopsy of the CVC mass were consistent with pheochromocytoma. On electron microscopic view norepinephrine specific granules were found in the cytoplasm of tumor cells.

This experiments was designed to observe the effect of period and dose of ingestion of grapes on renal failure in dog. After the dogs had been mixed of general feed, raisins from U.S.A and fresh grapes from Chile selling in Korea. We observed the clinical sign, and analyzed the blood and urine using by biochemical test. The experiment was executed by the two following groups. The experiment group 1. derived renal failure by supplying the mixed general feed with fresh grapes and dry grapes 15 g per weight kg, 2 times a day (AM 09, PM 21), the experiment group 2. executed to derive renal failure by supplying the mixed general feed with fresh grapes and dry grapes 40 g per weight kg, 2 times a day. Extraction of blood for analysis was conducted one time a day and clinical test for renal failure was executed by means of a blood analysis, biochemical analysis, urine analysis, excretory urography (E.U) and E.R.D-$screen^{TM}$ urine test (Heska, USA). The results of group 1 were normal ranges (BUN 9.0~22.6 mg/dl, creatinine 0.8~1.2 mg/dl, Ca 9.7~12.3 mg/dl, Pi 2.9~4.6 mg/dl), renal failure was not observed. On the 3rd day in group 2, azotemia was arisen from the increasing BUN 83 mg/dl (7~25 mg/dl), creatinine 2.3 mg/dl (0.5~1.4 mg/dl), when executed urine was tested by E.R.D-$screen^{TM}$ test using in the early kidney disease diagnosis, microalbumine state was high positive, and it showed stale delay by using excretory urography (EU). This study demonstrated that acute renal failure by grapes and raisins dependent on food dose, and specific characters of individual.

Sotos syndrome (SS, OMIM 117550) is characterized by prenatal and postnatal overgrowth with multiple congenital anomalies. However, there have been few cases of growth retardation caused by renal failure from infancy. We report a case of dysplasia of the bilateral kidneys with renal failure and poor postnatal growth. A 2-month-old boy visited the emergency room owing to poor oral intake and abdominal distension. He was born at the gestational age of 38 weeks with a birth weight of 4,180 g. After birth, he had feeding difficulty and abdominal distension. Upon physical examination, his height and weight were in less than the 3rd percentile, while his head circumference was in the 50th percentile on the growth curve. He also showed a broad and protruding forehead and high hairline. Blood laboratory tests showed severe azotemia; emergent hemodialysis was needed. Abdominal ultrasonography revealed bilateral renal dysplasia with multiple cysts and diffuse bladder wall thickening. A posterior urethral valve was suggested based on vesicoureterography and abdominal magnetic resonance findings. Results of a colon study to rule out congenital megacolon did not reveal any specific findings. The conventional karyotype of the patient was 46, XY. Array comparative genomic hybridization study revealed a chromosome 5q35 microdeletion including the NSD1 gene, based on which SS was diagnosed. We describe a case of SS presenting with end stage renal disease due to posterior urethral valve. The typical somatic overgrowth of SS in the postnatal period was not observed due to chronic renal failure that started in the neonatal period.

Dehydration, electrolyte disturbance, and acid-base imbalance are the most significant consequences of diarrhea in calves. We aimed to determine blood gas, hematological, electrolyte, and biochemical values and investigate the relationship between the physical status and blood parameters in Korean native calves (KNCs) with diarrhea. One hundred eighty KNCs with diarrhea (age < 75 days) were investigated. Blood samples were collected from the external jugular vein and analyzed using a portable clinical blood gas analyzer. The measured parameters were statistically compared according to the status of physical activity, dehydration, or prognosis. The mean values of parameters in the Calves with diarrhea showed metabolic acidosis, hyponatremia, and azotemia. The mean values of potassium, chloride, hematocrit, and hemoglobin were in the upper limit of their reference ranges. More than 75% of the calves had metabolic acidosis caused by bicarbonate loss, and 63.6% had high blood urea nitrogen (BUN) values. Moreover, BUN showed the highest correlation with the physical activity status and dehydration. pH, base excess of the extracellular fluid (BE), anion gap, potassium, hematocrit, bicarbonate, and hemoglobin were closely correlated with physical deterioration and dehydration (p < 0.001). BUN, pH, BE, and anion gap were closely correlated with physical deterioration and dehydration. These correlations between clinical symptoms and blood gas parameters can be clinically relevant in predicting the status of parameters according to clinical symptoms.

Among several diseases of calves, diarrhea is the most prevalent disease and has been a major cause of economic loss to the cattle industry. The main etiologic agents of diarrhea in calves are bacteria, viruses, and protozoa, but non-infectious factors including foreign bodies obstruction in the digestive system also focused as the cause of calf diarrhea in the recent days. Because there is still limited information for foreign body-related diarrhea in calves, especially in Hanwoo, the present retrospective study reviewed the medical records for diarrheic calves with foreign body in the digestive system (n=32). The morbidity was determined as 3.03% and more than half of them presented the acidosis, hyponatremia, and azotemia. The mortality in laparotomy-operated calves to remove foreign bodies or in non-operated ones was 28% or 85.7%, respectively, implied the importance of aggressive decision for laparotomy when the foreign bodies were determined in the digestive system in diarrheic calves. During laparotomy, trichobezoars (hair balls) and hays were the main foreign bodies and prevalently placed in the abomasum. In the trials to predict prognosis by several clinical factors, the time for laparotomy over 2 days after first diagnosis, acidosis, and foreign body in the abomasum were highly associated with mortality. Therefore, we believe that prompt surgical procedure (laparotomy) is necessary upon obstruction in the digestive system by foreign bodies is tentatively diagnosed in the diarrheic calf. In addition, when differential diagnosis list is made, foreign body-related diarrhea is necessary to be included in case of diarrheic calf.

목 적 : 요로 기형은 선천성 기형중 가장 높은 빈도를 차지하며 조기 진단에 어려움이 많아 발견당시 이미 비가역적인 신손상을 초래할 수 있다. 이에 본 연구는 소아에서 요로계의 선천성 기형의 임상상을 조사하고 이에 대한 적절한 진단과 치료 방법을 알아보고자 시행되었다. 방 법 : 조사 대상은 1987년부터 1998년까지 10년간 경북대학교병원 소아과에서 선천성 요로기형으로 진단된 65명의 환아로 하였고 후천적으로 발생한 수신증과 방광요관 역류 등은 제외시켰다. 이들 환아에 대한 임상상과 치료 및 경과를 임상 기록을 토대로 후향적 조사를 하였다. 결 과 : 요로계 기형의 빈도는 신우요관 이행부 협착이 26례로 가장 많았으며 그외 중복 요로계 11례, 일측성 신무형성 10례, 방광요관 이행부 협착 7례 등의 순이었다. 이중 8례에서 한가지 이상의 요로계 기형이 동반된 복합 기형을 나타내었으며 11례에서는 선천성 심장병과 같은 타 장기의 기형이 동반되어 있었다. 진단 당시의 연령 분포는 1세 이하가 39명($60\%$)으로 가장 많았고 남녀 비는 2.25:1로 남아가 많았다. 내원시 주 증상은 요로 감염이 25례로서 가장 많았고, 그외 혈뇨, 복부 종괴, 패혈증, 복통, 배뇨 이상 등이 있었다. 산전 초음파검사로 발견된 경우가 11례였고 입원시 고질소 혈증을 보인 경우는 모두 9례로서 이중 4례는 신우요관 이행부 협착, 방광요관 이행부 협착 및 중복 요로계등의 요로계 폐쇄질환이었다. 수술적 교정은 총 73례의 기형중 38례에서 시행되었다. 고질소 혈증을 보인 폐쇄성 요로 기형 4례중 1년에서 5년까지의 추적관찰 기간중 2례에서 고질소 혈증이 소실되었으며 같은 추적관찰 기간중 새로이 신기능 저하를 일으킨 례는 없었다. 결 론 : 요로의 선천성 기형은 높은 빈도로 발생함에도 불구하고 특이적인 증상을 나타내지 않아 조기 진단에 어려움이 많다. 그러므로 요로 감염, 복통, 배뇨 곤란 등의 증상이 있는 환아에서는 요로 기형의 존재 여부를 반드시 확인하여야 하며 특히 산전 초음파검사의 광범위한 이용으로 요로 기형의 존재 여부를 조기에 진단하고 이에 대한 적절한 조처를 행함으로서 신장의 비가역적 손상을 예방할 수 있을 것으로 생각한다.

Renal dysfunction could be developed as the secondary disease of liver cirrhosis. Delayed or suppresed lipid peroxidation by the treatment with physiological active substances could be explained as the antioxidative and protective effect in tissue damage. In this study, we investigated an antioxidative effect and renal function improvement of Hovenia dulcis in liver fibrosis(cirrhosis) induced rats. The female Sprague-Dawley rats (180∼210 g) were divided into 3 groups (Normal, AC: CCl₄ mixture treated group, AC-HV: CCl₄ mixture+ Hovenia dulcis treated group) and renal damage was developed by CCl₄ mixture administration in 4 weeks (0.8 ㎖/rat). The tissue of kidney and liver and sera were used for quantitative measurement of enzyme activity, MDA and Hyp. The histological change and gene expression of collagen α1(III) mRNA and a1(IV) mRNA were observed by Masson's trichrome staining and RT-PCR. As a result, the clinical biochemical parameters of liver function (AST and ALT) in sera of AC-HV group showed significantly 46.4% and 104.8% lower (p<0.005), and the level of ALP and BUN as the parameter of protein urine and azotemia showed 17.8 % and 25.8 % lower than in AC group. In AC-HV group, the concentration of MDA in kidney and liver was decreased significantly 15.8% and 21.3% when compared with AC group (p<0.01 -0.005). The content of Hyp in kidney of AC-HV group is merely higher than in AC group, in contrast to liver tissue. The expression of collagen α1(III) mRNA and collagen α1(IV) mRNA was decreased in AC, but both of collagen mRNA in normal and AC-HV group expressed fast similar. More massive lipid droplets, thicker collagen fiber bundles in portal triads and more formation of portal central septum were observed in the liver of AC group than in AC-HV group. In conclusion, CCl₄ mixture intoxication could be developed not only liver fibrosis(cirrhosis) but also renal dysfunction by the massive lipid peroxidation and suppression of interstitial collagen and basement membrane collagen synthesis. And the water extract of Hovenia dulcis may be possessed the antioxidative and protective effect and improvement of kidney function in renal dysfunction induced rats.
