The diagnostic method was, evaluated in experimentally induced acute renal failure in doges. Ten male dogs weighing from 5 to 10 kg were assigned to two groups(gentamicin & ethylene glycol treated group) al random. Gentamicin sulfate at 10 mg/kg of body weight, t.i.d., for 7 days and ethylene glycol at 3 ml/kg of body weight once used in a randomized complete block design with tee treatments in block. The samples(blood, urine) were collected before and 1,3,5,7,9 and l1th day after administration. The serum creatinine concentration and BUN(blood urea nitrogen) were sig- nificantly increased at the 7th day than before administration in gentamicin treated group (p<0.05), bolt there was significant increase at the 1st day than before administration in ethylene glycol treated group(p<0.05). The urine GGT(gramma glutamyl transpeptidase) and GGT/creatinine were significantly increased at the 1st (lay after administration in gentamicin treated group (p<0.05). But in ethylene glycol treated group, there was no significant changes. The value of FENa (fractional excretion of sodium) was significantly increased at the 3rd day after administration in gentamicin treated group and the 1 st day after administration in ethylene glycol treated group (p<0.05). These results suggest that FENa was a good parameter of renal function in dogs with acute renal failure.

Objectives : Chronic renal failure(CRF) is a pathophysiologic process with multiple etiologies, resulting in the inexorable attrition of nephron number and function and frequently leading to end-stage renal disease. It causes various symptoms(edema, general body weakness, nausea, anorexia, uremia, osteodystrophy and so on) which impair quality of life and long term complications. The purpose of this case is to report the improvement of a patient with chronic renal failure. Methods : We treated the patient with herbal medication(Gyulpyjeonwon) and measured the creatinine, BUN, albumin, hemoglobin in the serum. Results : Gyulpyjeonwon decreased serum creatinine and BUN level and increased serum albumin and hemoglobin level. And the symptoms of CRF(edema, general body weakness, anorexia) was improved significantly. Conclusions : This case suggests the efficacy of herbal medication(Gyulpyjeonwon) to patient who was involved CRF.

Cystatin C, a low-molecular-weight protein synthesized by cells, is being explored as a valuable biomarker for assessing renal function in veterinary medicine. Although the relationship between cystatin C and heart disease remains unclear, some studies suggest a possible association. This retrospective case-control study aimed to investigate the role of cystatin C as a biomarker for heart disease and its correlation with diuretic use in veterinary clinical practice. A total of 39 dogs were included in this study, comprising 9 control dogs without a predisposition to heart disease and 30 dogs in the study group diagnosed with heart disease. Among the 30 dogs with heart disease, 18 exhibited symptoms indicative of heart failure. Results showed significantly higher cystatin C levels in the heart disease group compared to the control group (P<0.05). However, no significant differences were observed among different stages of heart disease severity in the control group. Furthermore, cystatin-C showed statistically positive correlations with BUN (r=0.478, P<0.01), creatinine (r=0.506, P<0.01), and furosemide (r=0.338, P<0.05). Diuretics are essential for managing congestive heart failure, and the observed associations between cystatin C and furosemide suggest potential impacts of diuretic use on renal function in dogs with heart failure. Monitoring renal function markers, such as cystatin C, can aid in predicting and managing potential renal complications, ultimately improving the overall health and quality of life of dogs with heart disease.

Since the first report of coronary artery bypass grafting (CABG) in patients with end-stage renal disease in 1974, numerous reports have documented the feasibility of CABG in patients with chronic renal diseases. Patients with chronic renal failure often have comorbid disorders such as hypertension, and diabetes mellitus, each with their own complications and associated impact on both short and long-term survivals. In addition, infection and sepsis have been identified as significant causes of morbidity and mortality in most series of patients with end-stage renal disease undergoing cardiac surgical procedure. As a result of these and other factors such as perioperative volume and electrolyte disturbances, patients with chronic renal failures are at an increased risk of complication and mortality after CABG. We report 3 cases of "Off-pump" CABG in the chronic renal failure patients. patients.

Two dogs were referred due to vomiting, depression and anorexia after ingestion of xylitol gum. Both dogs were presented with hepatic failure and one dog had concurrent renal failure. Aggressive supportive treatment was performed, but these dogs died. Necropsy of one dog revealed acute hepatic necrosis, severe renal damages, and hemoperitoneum. This case report demonstrates potential hazard of xylitol toxicity for dogs with clinicopathological and pathological findings.

Endothelin-1 (ET-1) is unequivocally elevated in the kidney with ischemic acute renal failure (ARF), whereas ET receptors ($ET_AR$ and $ET_BR$) are variably expressed. Although renal functional and structural changes are similar between ischemic and nephrotoxic ARF, there are few reports on the alteration in the ET system in nephrotoxic ARF. This study was, therefore, undertaken to investigate changes in renal expression of ET-l and its receptors in nephrotoxic ARF induced by cisplatin. Mice were intraperitoneally injected with 16 mg of cisplatin/kg at a single dose, and the expression of mRNA and protein was then quantified by real-time RT-PCR and Western blot, respectively. Immunohistochemistry was conducted for localization. Three days after treatment, ET-1 transcript in cisplatin-treated mice was thirteen times higher than that in controls, whereas ET-1 peptide was increased by 1.5-fold. Cisplatin caused a 2-fold increase in the levels of ETAR mRNA and protein. Most of the increased immunoreactive ET-1 and ETAR were localized in damaged tubules. Neither the expression of ETBR mRNA nor the abundance and immunoreactive level of ETBR protein were changed. The findings suggest that the individual components of the renal ET system are differentially regulated in cisplatin-induced nephrotoxic ARF.

A 56-year old female underwent total aortic arch replacement March 1995, because of an expanding chronic Debakey type I aortic dissection. This aortic dissection had an intimal tear at the origin of the right carotid artery. Retrograde and antegrade propagation of dissection resulted in aortic arch blood flow separation and expanding pseudolumen to the abdominal aorta. Sudden anuria(ARF) developed 3 hours later postoperatively and renal doppler ultrasonography and aortography showed diminished blood flow of renal arteries. We performed balloon aortic dilatation but failed. She could be restored good renal flow after intimal flap fenestration resection and thrombectomy of the abdominal aorta. This patient could be discharged in a state of mild CRF after 2 months of ICU care for respiratory and renal failure.

Disease, such as osteopenia, osteoporosis, etc caused by reduced bone density are common to women after menopause and as the social medical cost increases due to osteoporosis fractures the medical interest in bone density reduction has increased. The bone density reduction is observed even for renal failure patients, due to their decreased ability to synthesize vitamin D which leads to bone fibrosis because of deficiency in calcium absorption. Thus renal failure patients not only suffer from kidney dysfunction, but also are exposed to complications, such as osteoporosis, due to reduced bone density. This research observed the change in bone density of patients receiving renal failure treatment and analyzed the change in bone density before and after kidney transplantations. Subjects were 214 renal failure patients at the department of nephrology Busan B General Hospital. The change in bone density was studied for subjects with and without kidney transplantation according to their age and sex. The research showed improvement or maintenance of bone density for subjects that received kidney transplantation, but showed a tendency of consistent decrease in bone density for subjects without kidney transplantation. Kidney transplantation can be considered as the best cure for renal failure patients, and this researched confirmed that bone density can be improved through kidney transplantation. Thus, this study can also be used as data for preventing complications due to renal failures.

The present study was designed to examine whether water extract of Acanthopanacis cortex(AC) has an effect on renal functional parameters in association with the expression of aquaporin 2 (AQP-2) and heme oxygenase-1 (HO-1) in the ischemia/reperfusion induced acute renal failure (ARF) rats. Polyuria caused by down-regulation of renal AQP 2 in the ischemia-induced ARF rats was markedly restored by administration of AC (200 mg/kg, p.o.) with restoring expression of AQP 2 in the kidney. Administration of AC lowered the renal expression of HO-1, which was upregulated in rats with ischemia/reperfusion-induced ARF. The renal functional parameters including creatinine clearance, urinary sodium excretion, urinary osmolality, and solute-free reabsorption were also markedly restored in ischemia-ARF rats by administration of AC. Histological study also showed that renal damages in the ARF rats were abrogated by administration of AC. Taken together, the present data indicate that AC ameliorates renal defects in rats with ischemia/reperfusion-induced ARF.

Acute renal injury induced by ischemia is a major cause of high morbidity and mortality in hospitalized patients and a common complication in hospitalized patients. Thus, the work with acute renal failure and renal ischemia has been studied for many years. Although serum creatinine concentration that is widely used as an index of renal function performs fairly well for estimating kidney function in patients with stable chronic kidney disease, it performs poorly in the setting of acute disease. Thus, an ideal biomarker for acute kidney injury would help clinicians and scientists diagnose the most common form of acute kidney injury in hospitalized patients, acute tubular necrosis, early and accurately, and may aid to risk-stratify patients with acute kidney injury by predicting the need for renal replacement therapy, the duration of acute kidney injury, the length of stay and mortality. In this study, renal ischemia and reperfusion were performed by clapming and un-clamping right renal artery in miniature pigs. Plasma blood urea nitrogen (BUN) and creatinine were examined at pre- clamping, after-clamping at 0, 1 and 3 hours. And we searched initial indicators in these samples. Also, renal tissue was collected and searched the initial indicator by PCR and western blotting. As a result, hypoxia inducible factor $1{\alpha}$ ($HIF1{\alpha}$), nuclear factor kappa-B ($NF{\kappa}B$), $I{\kappa}B$, erythropoietin (EPO), erythropoietin receptor (EPOR), angiopoietin-1 and vascular endothelial growth factor (VEGF) were showed significant changes among the renal protein. $HIF1{\alpha}$, EPO, and EPOR were showed significant changes among the renal gene. Thus, these markers will be used as initial diagnosis of acute renal failure.
