These studies were conducted an attempt to investigate effects of 'Paeryungtang' and 'Kamipaeryungtang' water extracts on diuretic, antipyretic, antiinflammatory and analgesic actions. The results of these studies were summarized as follows; Increase in urinary volume, urinary $Na^+$ excretions were significantly recognized in normal rat. Increase in urinary volume, urinary $Na^+\;and\;Cl^-$ excretions were significantly shown in rat with 2mg/kg $HgCl_2$-induced acute renal failure. Antipyretic, anti-inflammatory and analgesic effects of 'Paeryungtang' and 'Kamipaeryungtang' were recognized in mice, rats and rabbits.

Russell-Silver 증후군은 자궁내 성장 지연, 특징적인 얼굴 기형, 저신장을 특징으로 하는 질환이다. Russell-Silver 증후군에서 동반되는 신질환은 말굽 신장, 신세뇨관 산증, 물콩팥증, 요관 깔때기막힘, 방광 요관 역류 등이 있다. 저자들은 Russell-Silver 증후군 환자에서 말기 신부전이 발생한 예를 경험하였으며 문헌 고찰에서 유사한 증례를 찾을 수 없었기에 보고하는 바이다.

Symmetric dimethylarginine (SDMA) is a new renal biomarker for kidney function. It is almost exclusively eliminated by renal filtration. The purpose of this retrospective study was to evaluate the changes in serum ceatinine (CREA), blood urea nitrogen (BUN) and SDMA concentrations in dogs with chronic mitral valve insufficiency (CMVI), according to the severity of CMVI. The evaluation of the severity of CMVI was performed according to the American College of Veterinary Internal Medicine (ACVIM) classification of heart failure. The dogs were classified into two groups: group 1 (ACVIM B; n = 11) and group 2 (ACVIM C; n = 15). In dogs with advanced CMVI, the serum SDMA concentrations were significantly increased above the normal reference range and were independent of body weight (BW), systolic blood pressure (SBP), or sex. No dog in either group had higher serum CREA concentrations than the upper limit. The serum SDMA concentration may be a better renal marker than serum CREA concentrations for the early diagnoses of renal dysfunction in dogs with CMVI.

Tumor necrosis factor-α (TNF-α) or its mRNA expression are increased in acute nephrosis of various types including ischemia/reperfusion injury. This study was undertaken to determine whether pentoxifylline (PTX), an inhibitor of TNF-α production, provides a protective effect against hypoxia-induced cell injury in rabbit renal cortical slices. To induce hypoxia-induced cell injury, renal cortical slices were exposed to 100% N₂ atmosphere. Control slices were exposed to 100% O₂ atmosphere. The cell injury was estimated by measuring lactate dehydrogenase (LDH) release and p-aminohippurate (PAH) uptake. Exposure of slices to hypoxia increased the LDH release in a time-dependent manner. However, when slices were exposed to hypoxia in the presence of PTX, the LDH release was decreased. The protective effect of PTX was dose-dependent over the concentrations of 0.05∼1 mM. Hypoxia did not increase lipid peroxidation, whereas an organic hydroperoxide t-butylhydroperoxide (tBHP) resulted in a significant increase in lipid peroxidation. PTX did not affect tBHP-induced lipid peroxidation. Hypoxia decreased PAH uptake, which was significantly attenuated by PTX and glycine. tBHP-induced inhibition of PAH uptake was not altered by PTX, although it was prevented by antioxidant deferoxarnine. The PAH uptake by slices in rabbits with ischemic acute renal failure was prevented by PTX pretreatment. These results suggest that PTX may exert a protective effect against hypoxia-induced cell injury and its effect may due to inhibition of the TNF-α production, but not by its antioxidant action.

The recent outbreak of renal failure in infants in China and in animals in USA and Europe has been determined to be caused by melamine adulterated in the food. In the course of the investigation, cyanuric acid was identified in addition to melamine in the offending food. Fish feeds were also recently found to be contaminated with melamine. The purpose of this study was to characterize the histopathological effect and toxicity potential of different concentrations of melamine and cyanuric acid in the kidney of Japanese catfish (Silurus asotus). The fish were administered melamine and cyanuric acid in combination at the concentrations of 12.5, 25, 50, 100 and 200 mg/kg/day for 3 days by single oral administration dissolved in carboxymethyl cellulose. The results showed that renal crystals were observed in renal tubules and collecting ducts at the concentration over 25 mg/kg dose group and the number of crystals in kidney were in proportion to the concentrations of melamine and cyanuric acid.

Distal renal tubular acidosis (dRTA) is a rare renal tubular disorder characterized by normal anion gap metabolic acidosis, hypokalemia, and high urine pH. It can be inherited or acquired. In untreated pediatric patients with dRTA, rickets and growth retardation are common. We report the case of a 12-year-old Lao girl who presented with typical clinical features of dRTA with severe bone deformities that developed after a bed-ridden state due to a bicycle accident at the age of 8 years. Initial laboratory tests revealed metabolic acidosis with a normal anion gap, hypokalemia, and alkali urine. Renal ultrasonography revealed bilateral medullary nephrocalcinosis. Whole exome sequencing revealed no pathogenic mutations. After treatment with oral alkali, potassium, and vitamin D, she could walk and run. Later, she underwent corrective orthopedic surgeries for bony deformities. Thus, in pediatric dRTA patients, despite severe symptoms remaining untreated, accurate diagnosis and proper management can improve quality of life.
