A 14-year-old intact male Siberian Husky was presented with hematuria, lethargy, and anorexia of 1-month duration. The physical examination revealed mild abdominal distension and pain. The hematology and serum chemistry revealed anemia and severe azotemia. The radiographic examination revealed renomegaly and the ultrasonographic examination, indistinct cortico-medullary junction, increased renal cortex echogenicity, and irregular margination. The urinalysis showed proteinuria and hematuria. The differential diagnosis included renal failure, cystitis, pyelonephritis, and neoplasia. The patient's condition continued to deteriorate, and the dog eventually died. The gross findings from the necropsy revealed hemoperitoneum and a bilateral renal mass. HSA was diagnosed by histopathological examination. This case report describes primary bilateral renal hemangiosarcoma (HSA), which is uncommon in dogs.
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.

Mortality and morbidity of malignant hyperthermia has decreased markedly by the avoidance of succinylcholine, and the earlier detection and introduction of dantrolene. We report a fourteen-year-old boy who developed malignant hyperthermia during general anesthesia. He showed the earlier clinical signs, such as elevation of end-tidal $CO_2$, tachycardia, and hypertension. After prompt administration of dantrolene, operation was continued with profopol and midazolam. Rhabdomyolysis and myoglobinuria followed, and were managed by hydration and alkalinization of urine. Azotemia did not occur, and he was discharged without any sequelae on the $10^{th}$ postoperative day.

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.

Purpose : Malformation of urinary tract is among the most common of all congenital anomalies and can progress to irreversible renal damage before diagnosis due to difficulty of early diagnosis. Present study was undertaken to determine the clinical characteristics of urinary tract anomaly and to find out the most appropriate diagnostic and therapeutic measures for children with these anomalies. Methods : During the past 10 years from 1987 to 1998, review of medical records revealed 65 children with congenital anomaly of urinary tract and the following results were obtained. Results : The most common anomalies were ureteropelvic junction obstruction occuring in 26 cases ($36\%$), followed by ureteral duplication in 11 cases, renal agenesis in 10 cases and ureterovesical function obstruction in 7 cases. Complex anomaly of urinary tract was found in 8 cases and anomaly of other systems such as congenital heart disease was detected in 11 cases. The most frequent age group at the time of diagnosis was below 1 year of age constituting 39 cases ($60\%$) and male preponderance was noted as male to female ratio being 2.25:1. Presenting symptoms were urinary tract infection in 25 cases, followed by hematuria, abdominal mass, abdominal pain and voiding difficulty, etc, and in 11 cases, the anomaly was picked up by routine prenatal ultrasonography. Azotemia was noted in 9 cases and the underlying anomaly was obstructive uropathy in 4 out of these 9 cases. Surgical correction was undertaken in 38 cases (most frequently in cases of obstructive uropathy) and in 2 out off cases with obstructive uropathy in whom surgical correction was done, azotemia disappeared during follow up period of 1-5years. No new cases of deteriorating renal function appeared during follow-up period. Conclusion : In spite of high incidence of congenital malformation of urinary tract, early diagnosis is still hampered by nonspecific symptoms and signs. Therefore, in patients with symptoms such as urinary tract infection, abdominal pain and voiding problems, etc, it Is advisable to take various diagnostic tests promptly to pick up any urinary tract anomaly and to apply proper therapy in order to avoid progression to irreversible renal damage. In this regard, prenatal ultrasonography should be utilized more widely as a routine procedure to detect any urinary tract anomalies before birth.
Cardiac output, plasma volume and renal plasma flow were determined to evaluate hemodynamic changes in 29 patients with cirrhosis of the liver. The results obtained were as follows. 1. The mean plasma volume was 3793+895ml and it was significantly higher than the normal controls. The mean blood volume ($5266{\pm}1222ml$) and blood volume per kg body weight ($95.7{\pm}23.41ml$) were also increased significantly. The mean plasma volume per kg body weight ($69.1{\pm}19.1ml$) showed increased tendency and the mean difference between blood volume and plasma volume per kg body weight ($26.4{\pm}7.05ml$) was in lower limit of normal range. 2. The mean cardiac output was $7708{\pm}2652ml/min$ and it was significantly increased. The mean cardiac index ($4924{\pm}1998ml/min/M^2$), stroke volume ($96.2{\pm}34.2ml/beat$), stroke index ($62.3{\pm}27.34ml/M^2$) and fractional cardiac index ($1.54{\pm}0.577$) were also increased significantly. The mean total -peripheral resistance was $1664{\pm}753.8\;dynes\;sec\;cm^{-5}M^2$ and it was significantly lower than the normal controls. 3. The mean renal plasma flow was $537{\pm}146.8ml/min/1.73M^2$ and it was normal to decreased tendency. The mean endogenous creatinine clearance ($66.7{\pm}23.0ml/min/1.73M^2$) was significantly decreased. Filtration fraction was variable, but it was slightly lower than normal in most cases. The mean renal fraction of cardiac output ($11.4{\pm}6.27%$) was relatively decreased. 4. Although renal plasma flow was normal or decreased in general, it was definitely diminished in patients with creatinine clearance less than $60ml/min/1.73M^2$, resistant ascites, and signs of azotemia (elevated BUN and serum creatinine). 5. Diminished glomrular filtration rate with low filtration fraction and decreased renal fraction of cardiac output observed strongly supported increased renal afferent arteriolar resistance. 6. Renal circulatory impairment preceded azotemia or oroliguria in cirrhosis. 7. Clinical findigns and liver function were not correlated with hemodynamic changes, except for esophageal varices associated with high cardiac output obsedved. 8. No definite correlation of renal hemodynamics with plasma volume or cardiac output was found.

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.
