Objectives : To establish objective and scientific evidence of Korean medicine (KM), the papers on Oryeong-san (Wuling-san) frequently used in medical institutions of Korean Medicine were analyzed. Methods : The papers were classified by the registration of domestic or international journals, the year of publication, experimental fields and the kinds of studies on biological activities. The therapeutic mechanism was investigated in accordance with therapeutic effect of Oryeong-san (Wuling-san). Results : Out of 57 articles selected, 16 were published in domestic journals, 17 were in Chinese journals and 24 were in Japanese journals. Most papers reported as biological activities were on improvement of renal function. Oryeong-san (Wuling-san) increased urine factor such as urine excretion and electrolyte balance while decreasing proteinuria, serum factors including creatinine, cholesterol and triglyceride. In addition, injured renal tissue was recovered normally and gene expression controlling urine excretion was down-regulated. Conclusions : Improvement of renal function could be interpreted as objective and scientific evidence for Oryeong-san (Wuling-san).

Glomerulonephritis (GN) is sometimes associated with infective endocarditis (IE). Bartonella endocarditis is difficult to diagnose because it is rare and cannot be detected by blood culture. This is the first report of cytoplasmic anti-neutrophil cytoplasmic antibody-positive subacute endocarditis-associated GN caused by Bartonella infection in South Korea. A 67-year-old man was hospitalized due to azotemia. He complained of weight loss and anorexia for 6 months. A diagnosis of IE was made based upon echocardiographic detection of vegetations on the mitral and aortic valves and a Bartonella antibody titer of 1:2,048. Renal histology identified focal crescentic GN. Azotemia and proteinuria improved after doxycycline and rifampin treatment combining with steroid therapy.

The author was used for the ICR mouse and induced diabetes with the streptozotocin(50mg/kg)and alloxan(40mg/kg). After the testing and the identifying the diabetes, the histological changes of the glomerulus, blood test for the values of blood sugar, and urine test for the values of urine protein were investigated. The results are as follows : 1. The values of high blood sugar appeared from the 2 group were about $378mg/d{\ell}{\sim}709mg/d{\ell}$, in the treated groups with the streptozotocin and alloxan. The glycosuria were obviously continued from the 2 weeks to the 12 weeks of the streptozotocin and the alloxan treated groups and the proteinuria was ${\pm}{\sim}+$ in the 4 weeks and 8 weeks of streptozotocin treated group and were + in all the 12 weeks. The ketonuria were generally negative. 2. In the view of the light microscope, there was no significant histological changes until the 8 weeks. However, in the 12 weeks group treated with the streptozotocin, the mesangial matrix of glomerulus increased Bowman's capsules adhered to each other and changed them to the crescence shapes because of increasing the exothelial cells.

Chyluria is the passage of milky urine due to the leakage of lymph into the urinary tract. Chyluria occurs predominantly in adults and is rare in children. We present an unusual case in which a child with proteinuria, hematuria and milky urine was subsequently diagnosed with non-parasitic chyluria. Retrograde cystogram confirmed a lymphatico-calyceal communication. This case showed spontaneous remission. The etiology of this case was not exactly known; however, the prognosis of non-parasitic chyluria (or idiopathic chyluria) is usually very good and the treatment is mostly conservative.

Minimal change nephrotic syndrome is characterized by proteinuria, hypoproteinemia, edema, and hyperlipidemia. Children with onset of nephrotic syndrome between the age of 1 and 8 year are likely to have steroid response to minimal chage disease, but we experienced one case of minimal change disease which failed to respond to steroid therapy at beginning and subsequently developed acute renal failure. It was seen in a 5 year-old male child that presented with edema and gross hematuria. Peritoneal dialysis was performed for acute renal failure for 11 days. Patient was completely recorvered from acute renal failure and renal biopsy was done at 27th day after onset of disease which revealed typical picture of minimal change disease complicated by acute tubular necrosis. We beleive this case is very unusual and it may be the first case in the literature in terms of pediatric cases.

Despite wide therapeutic use of CpG ODN against infection, allergy and cancer, the safety and toxicity of CpG ODNs were poorly delineated. Thus, we investigated whether optimal dosing of CpG ODN would affect immunotoxicological parameters in NZB/NZW F1 mice. Comparisons were made among control, non-CpG ODN and mouse CpG ODN ($10{\mu}g$)-treated groups for 4 weeks. To gauge the immunotoxicity of CpG ODNs, we measured nonspecific parameters, degree of lupus nephritis, proteinuria, or autoantibody, and cytokine expression in mRNA level of lymphocytes. We found that there were no significant differences among groups in nonspecific immunotoxicological profiles and in evaluation profiles of glomerulonephritis. However, titer of anti-dsDNA and anti-cardiolipin antibodies in mouse CpG ODN group rose three or eight-fold higher than in control group. Collectively, CpG ODN might be clinically less immunotoxic in terms of clinical profiles in lupus-prone NZB/NZW F1 mice, in spite of high autoantibody titer in CpG ODN treated groups.

An 8-year-old castrated male Cocker Spaniel (weighing 12.0 kg) was referred to the Kangwon National University Veterinary Teaching Hospital, with primary complaints of persistent hematuria. Diagnostic studies revealed neutrophilia, hematuria, proteinuria, abnormal irregular shaped hyperechoic lesion in urinary bladder. The lesion was demarcated from the intact region of bladder and consisted of eosinophils, macrophages, lymphocyte and fibrocytes. Based on the histopathological exam, the case was diagnosed as eosinophilic polypoid cystitis and treated by surgical removal and short-term medical therapy (meloxicam and amitriptyline). The therapy was successful and recurrence has not been occurred.

This study was performed to investigate the effects of n-3 fatty acids on renal function in male Sprague-Dawley rats of different ages 5-, 15- and 19-months old. The rats were fed a 20%(w/w) lipid diet containing 10% fish oil, compared with control animals fed a 20% lipid diet without fish oil for 4 weeks. The results were as follows: kidney weights were significantly higher in fish oil-fed rats compared to control rats. Plasma levels of total lipid, total cholesterol, and triglyceride markedly increased, with aging and LDL-cholesterol showing a significantly lower level in fish oil-fed rats than control rats. The urinary protein and glomerular filtration rate (GFR) increased with aging. GFR was higher in fish oil-fed rats. However, urinary protein was the same in the two groups. Renal medulla thromboxane B$_2$(TXB$_2$)tended to be lower in fish oil-fed 19-month-old rats. Urinary TXB$_2$and PGE$_2$were found to be higher proteinuria. Light microscopic examination showed interstitial inflammation, tubular atrophy, interstitial fibrosis and glomerular mesangium increase. Although glomerular sclerosis increased with aging, fish oil in the diet had no effect on histological changes. In conclusion, plasma lipid, urinary protein excretion and renal histological change showed a significant increase with aging. The reduction of TXB$_2$in the medulla and increase of GFR caused by fish oil indicated n-3 fatty acid could affect renal function in line with the hypolipidemic effect.

To elucidate the mechanism of gentamicin induced renal dysfunction, renal functions and activities of various proximal tubular transport systems were studied in gentamicin-treated rats (Fisher 344). Gentamicin nephrotoxicity was induced by injecting gentamicin sulfate subcutaneously at a dose of 100 $mg/kg{\cdot}day$ for 7 days. The gentamicin injection resulted in a marked polyuria, hyposthenuria, proteinuria, glycosuria, aminoaciduria, phosphaturia, natriuresis, and kaliuresis, characteristics of aminoglycoside nephropathy. Such renal functional changes occurred in the face of reduced GFR, thus tubular transport functions appeared to be impaired. The polyuria and hyposthenuria were partly associated with a mild osmotic diuresis, but mostly attributed to a reduction in free water reabsorption. In renal cortical brush-border membrane vesicles isolated from gentamicin-treated rats, the $Na^+$ gradient dependent transport of glucose, alanine, phosphate and succinate was significantly attenuated with no changes in $Na^+-independent$ transport and the membrane permeability to $Na^+$. These results indicate that gentamicin treatment induces a defect in free water reabsorption in the distal nephron and impairs various $Na^+-cotransport$ systems in the proximal tubular brush-border membranes, leading to polyuria, hyposthenuria, and increased urinary excretion of $Na^+$ and other solutes.

A 7-year-old, intact male Pomeranian(weighing 2.2 kg), was presented with clinical signs of prolonged anorexia, polydypsia/polyuria, severe azotemia, proteinuria and heart murmur. Diagnostic studies found chronic kidney disease, severe hypertension and hypertrophic cardiomyopathy. The dog was treated with 2-day peritoneal dialysis, blood transfusion, anti-hypertensive therapy with amlodipine and conservative therapies direct to chronic renal failure. This is a rare case of hypertensive cardiomyopathy complicated with chronic kidney disease in dogs.
