  • We describe the case of a Jindo dog that presented with a 2-month history of an abscess-like mass on the skin of the left hip. The patient was initially diagnosed with a suspected insect bite and was treated with a topical dressing. After observing no improvements, surgical debridement was done to remove the abscess. Nine days after surgery, the patient started showing severe anorexia, vomiting, lethargy, and oliguria. Azotemia was detected, and the patient was diagnosed with acute kidney injury. Ultrasonography depicted an abdominal mass (4.6 × 7.5 cm) in the right ureter, and severe hydronephrosis in the right kidney. The patient was euthanatized. Results of the necropsy, histopathologic examination, and immunohistochemistry for tumor cells, confirmed that the patient had developed hydronephrosis and disseminated histiocytic sarcoma which had metastasized to the lungs. To the best of our knowledge, this is the first report of acute renal failure produced by ureter invasion and urinary tract obstruction resulting from the abdominal mass of disseminated histiocytic sarcoma in dogs.

  • In this study the influence of Bradykinin, a biogenic polypeptide, on the excretory function of the dog kidney was investigated, utilizing the clearance and stop-flow method. The results are summarized as follows; 1) Bradykinin administered intravenously elicited a marked antidiuresis. 2) When given into the renal artery, however, prompt increase of the urine flow, sodium excretion and free water clearance without significant change in the glomerular filtration rate ensued. 3) It was also effective during an osmotic diuresis with 10% Mannitol infusion, though the response was not so marked. 4) The stop-flow experiment showed that sodium reabsorption in the proximal tubules is inhibited by the infusion of bradykinin into the renal artery. It was thus concluded that the diuretic effect of bradykinin given intra-arterially results from the inhibition of sodium transport in the proximal tubules.

  • In anesthetized dogs, antidiuretic action of intravenously administered BRL 34915 (10.0~30.0 $\mu$/kg) was blocked by renal denervation, whereas it was not affected by glibenclamide, a selective $K_{ATP}$ blocker, given into renal artery. Diuretic action in ipsilateral kidney produced by intrarenal administration of BRL 34915 was not influenced by renal denervation, but blocked completely by glibenclamide given into the vein. Above results suggest that the antidiuretic action of BRL 34915 is mediated by renal sympathetic nerves and the diuretic action is caused by opening of $K^+$ channel within kidney.

  • A patient (Pointer+Viszula mixed breed, 4 months old, male), with chief historic sign of acute vomiting, hemorrhagic diarrhea, anorexia and dyspnea during 4 days was admitted to College of Veterinary Medicine, Kyungpook National University. Necropsy findings were revealed ulcer and hemorrhage contained hemorrhagic diarrhea in gastrointestinal tract, severe emphysema and hemorrhage in the lung and kidney and cardiac hypertropy. Histopathological changes showed emphysema, hyperemia and hemorrhage in the lung, severe hyperemia, hemorrhage, hepatic vacuolation and cellular necrosis in the liver, hyperemia, hemorrhage, necrosis of tubular epithelium in the kidney, hemorrhage in cardiac muscle and hyperemia, necrosis and sloughing of epithelium in the intestine.

  • Five puppies, 14 days old in the same litter showed acute symptoms such as painful crying, anorexia, abdominal pain and depression with fatal terminations. Necropsy of a puppy revealed hemorrhagic and necrotic foci in the lungs and kidney. The histological lesions were characterized with fibro-necrotizing foci in the lungs, nonsuppurative encephalitis and intranuclear inclusions of liver cells. A cytopathogenic agent was isolated from the thoracic fluid of a dead puppy by cell culture with primary dog kidney cells. The puppies inoculated with the field isolate showed the same clinical signs and lesions as those of the spontaneous cases. Viral particles were observed in suspension of the isolated agent by electron microscopy. The primary dog kidney cells infected with the field isolate showed fluorescent foci against anti-CHV monoclonal antibody after FA stain. On these findings of the disease it was diagnosed as CHV infection. The report signifies the first description of an epizootic of CHV infection in Korea.

  • This study was attempted to investigate the effect of raclopride, a dopamine $D_2$ receptor antagonist, on renal function in dog. Raclopride (70-220$\mu\textrm{g}$/kg), when given intravenously, Produced antidiuresis along with the decrease in free water clearance ( $C_{H_2O}$), urinary excretion of sodium and potassium ( $E_{Na}$ , $E_{K}$), partially decreased osmolar clearance ( $C_{osm}$) and increased reabsorption rates of sodium and potassium in renal tubules ( $R_{Na}$ , $R_{K}$). Raclopride administered into a renal artery did not influence on renal function in small doses (10 and 30$\mu\textrm{g}$/kg), whereas exhibited the decrease of urine volume (Vol) and $C_{H_2O}$ both in experimental and control kidney in much dose (100$\mu\textrm{g}$/kg), at this time, the decreased rates of both Vol. and $C_{H_2O}$) were more prominent in control kidney rather than that elicited in experimental kidney, and then only via was decreased in control kidney but increased in experimental kidney. Raclopride administered via carotid artery (30-200$\mu\textrm{g}$/kg) did not influence at all on renal function. Antidiuretic action induced by raclopride given intravenously was not affected by renal denervation. Raclopride given into carotid artery was little effect on renal function without relation to renal denervation. Above results suggest that raclopride produces antidiuresis by potentiation of antidiuretic hormone (ADH) action in blood without increase of ADH secretion in posterior pituitary gland, it is not related to renal nerve function in dogs.ogs.s.

  • This study was performed to investigate the effects of renal denervation and cromakalim, a K+ Channel opener, on central diuretic action of glibenclamide, an ATP-dependent K+ Channel blocker, in dog. Diuretic action of glibenclamide administered into the vein was weakened markedly by renal denervation and pretreatment of of cromakalim. Above results suggest that central diuretic action of glibenclamide is mediated by renal nerves and K+ Channel localized in kidney.

  • An 11-year-old mixed breed male dog was presented with a thoracoabdominal wall mass of 3-year duration. Initial tentative diagnosis of osteosarcoma was made. Despite chemotherapy treatment, 72 days following the date of presentation, the dog was euthanized. Based upon necropsy and histopathologic findings, the tumor was definitely diagnosed as a combined type osteosarcoma of the rib. At necropsy examination, the tumor extended the left kidney and diaphragm, but distant metastasis was not found. The tumor's weight was 2.3kg and that was 38.3% of the dog's weight. This case report describes the clinicopathological, computed tomographic, histopathologic and immunohistochemical findings of extensive rib osteosarcoma in a small breed dog.

  • By employing the vinylite-and neoprene latex-corrosion technique, ramification and arrangement of A. renalis were observed in fifty Korean native goats (100 kidneys). The obtained results were as follows: 1. A single renal artery, arising on each side from abdominal aorta, bifurcated into Ramus dorsalis and Ramus ventralis from which 3~6 segmental arteries originated. 2. The dorsal and ventral surfaces of the kidney were divided separately into 3~6 arterial segments by the running of the segmental artery into the parenchyma. Of them four segments were mostly frequent (in 77% of right kidney and 83% of left). 3. In 25 of all the kidneys, either dorsal or ventral surface of a kidney was supplied from interlobar or segmental arteries belong to the opposite Ramus. 4. In 3 goats, A. polaris superior was observed. 5. Generally, distribution of the renal artery of Korean native goat resembled that of the dog.
