  • Purpose: Alport syndrome (AS) is one of the most common inherited renal diseases caused due to mutations of genes encoding specific proteins of the type IV collagen family, and its major clinical manifestations include progressive renal failure, sensorineural deafness, and ocular abnormalities. We investigated the clinical characteristics and long-term prognosis of AS in Korean pediatric and adult populations. Methods: We conducted a retrospective review of medical records of 33 children and adults who had been diagnosed or treated with AS from 1985 to 2019. Results: The mean age of the 33 patients diagnosed with AS was 16.2±13.6 years, and the male-to-female ratio was 2:1. At the first visit, recurrent gross hematuria was the most common initial symptom. In 10 of 33 patients (30.3%), sensorineural hearing loss (SNHL) was diagnosed, but none had ophthalmic problems. Moreover, 11 of 33 patients (33.3%) had advanced to end-stage renal disease (ESRD), and a significant difference was observed in the age of the patients who progressed to ESRD based on the presence or absence of SNHL (P=0.035). Conclusion: SNHL in AS can be an important prognostic factor for long-term deterioration of renal function. Further investigation is required to confirm the clinical course and the genetic characteristics of AS in Korea through prospective national cohort studies.

  • 신장 점액종은 신장에서 발생하는 드문 양성 종양이다. 최근까지 영미권에서 적은 수의 증례 보고가 되어 있으나 대부분의 경우 비뇨의학적 혹은 병리학적으로 접근하여 점액종의 영상의학적 소견은 잘 분석되지 않았다. 우리는 62세 남자 환자에서 발생한 신장 점액종의 영상 소견을 보고하고자 한다. 해당 종양은 좌측 신장동에 위치하고 있었으며, 자기공명영상의 T2 강조영상에서는 중등도의 고신호강도로 T1 강조영상에서는 저신호강도로 보였다. 또한 종양은 역동적 조영증강 영상에서는 점진적인 조영증강을 보였다.

  • Physico-chemical characterization of human renal dipeptidase was carried out. It was a glycoprotein with a subunit MW of approximately 47,700 dalton. The pH optimum was at 8 and its stable conformation was retained between pH 5 and 12. The kinetic parameters determined with imipenem, a noval ${\beta}-lactam$ antibiotic, were Vmax, $5.21\;\mu{mol/min/mg}$; km, 4.35 mM ; and Ki with cilastatin, $0.25\;\mu{M}$ Cilastatin demonstrated reversible competitive inhibition.

  • In order to investigate whether the function of distal nephron is disturbed in adenine-induced renal failure rats, we measured the urinary kallikrein level in adenine-ingesting rats fed on 0.75% adenine diet for 1 to 10 days. Administration of 0.75% adenine to rats significantly increased blood urea nitrogen level and urine volume, while the level of kallikrein along with the urinary excretions of urea and inorganic phosphate were significantly decreased. From these results, it is suggested that adenine-induced renal failure is caused by early deterioration of distal nephron as well as proximal nephron.

  • Ceramide induces cell death in a variety of cell types however, the underlying molecular mechanisms related to renal epithelial cells remain unclear. The present study was undertaken to determine the role of extracellular signal-regulated protein kinase (ERK) in ceramide-induced cell death in renal epithelial cells. An established renal proximal tubular cell line of opossum kidney (OK) cells was used for this research. Ceramide induced apoptotic cell death in these cells. Western blot analysis showed that ceramide induced activation of ERK. The ERK activation and cell death induced by ceramide were prevented by the ERK inhibitor PD98059. Ceramide caused cytochrome C release from mitochondria into the cytosol as well as activation of caspase-3. Both effects were prevented by PD98059. The ceramide-induced cell death was also prevented by a caspase inhibitor. These results suggest that ceramide induces cell death through an ERK-dependent mitochondrial apoptotic pathway in OK cells.

  • The parathyroid gland is probably the simplest endocrine organ in the body. The only cells of clinical significance are the parathyroid or chief cells. The primary signal that these cells listen to is calcium. Primary hyperparathyroidism is due to a parathyroid adenoma. The most common cause of hypercalcemia in veterinary medicine is hypercalcemia of malignancy associated with variety of neoplasms. Secondary hyperparathyroidism is due to a disease process, most commonly associated with renal and nutritional hyperparathyroidism. Primary and secondary hyperparathyroidism are markedly different in their clinical, laboratory, and pathogenic mechanism.

  • A case of renal candidiasis is reported in a 4-year-old male Masked Palm civet (Paguma larvata) On necropsy, the kidneys were bilaterally swollen, pale and had numerous 1 to 3 mm diameter white foci throughout the parenchyma on cut section. The urinary bladder was filled with opaque and milky exudate. Histologically, severe infiltration of neutrophils and macrophages and necrosis were noted in the interstitial areas of both cortex and medulla and in the lumens of renal tubules and collecting duct often resulting in cystic dilation of the tubules. PAS-positive fungal yeasts or pseudohyphae were often associated with the lesion. Candida albicans was isolated from the kidney and urinary bladder.
