【 摘 要 】

Acute renal failure is a condition in which kidneys are unable to eliminate all the waste from the body. Renal failure results in acid-base imbalance and electrolyte homeostasis. Na+-K+-2Cl- Cotransporter (NKCC2), Na+-Cl- Cotransporter (NCC) and Na+-K+-ATPase Cotransporter (Na+-K+-ATPase) are the important water and sodium channels proteins in the kidney. The aim of this study was to determine the gene expression level in the kidney of dogs suffering with the acute renal failure. A totalfour dogs with acute renal failure and four healthy dogs were used in this study.The biochemical analysis was done via semi-automatic biochemical machine, whilethe urine and urinary sediment examination was observed via microscopic study. The acute renal failure was diagnosed and confirmed via necropsy and histopathological examinations and finallythe protein expression was analyzed by immunohistochemistry.Results showed thatthe concentration of sodium, potassium, creatinine and urea nitrogen were significantly different from control group. The level of pH and specific gravity (SG) were decreased with urobilinogen (URO) and were increased during acute renal failure. The urinary sedimentation results revealed the presence of RBCs and WBCs in urine samples. The kidney volume was increased with renal capsule due to hyperplasia and renal pelvis expansion. The hydronephrosis was also observed along with hemorrhages, shrinkage, necrosis, and inflammation in acute renal failure groups by histopathology. The immunohistochemical results revealed thattheNKCC2, NCC and Na+-K+-ATPase were highly expressed in acute renal failure dogs. Therefore, it was concluded that sodium channels proteins possiblyplay an important rolein dog’s acute renal failure cases.
