E-cadherin is a cell adhesion molecule that is expressed abundantly in the kidney. However, the expression pattern in various renal epithelial cells is not well established. The purpose of this study was to determine the cellular localization along the nephron segments in the rat kidney. Kidneys from adult Sprague Dawley rats were fixed in 4% paraformaldehyde and processed for immunohistochemistry. Bumetanide-sensitive Na+/K+/2Cl- cotransporter (BSC1), thiazide-sensitive Na+/Cl- cotransporter (TSC), calbindin D28k, and H+-ATPase were used to identify the thick ascending, distal convoluted stubule, connecting tubule, and collecting duct, respectively. In the rat kidney, Ecadherin was expressed mainly in the basolateral domain of the collecting duct and papillary surface epithelial cells. The expression level of E-cadherin changed gradually in the connecting tubule and became moderate in the distal convoluted tubule, thick ascending limb, and loop of Henle. The S1 and S2 segment of the proximal tubule showed weak immunoreactivity. However, E-cadherin was not expressed in the S3 segment of the proximal tubule in the rat kidney. These results suggest that E-cadherin is a major adhesion molecule in the collecting duct and papillary surface epithelium, and that E-cadherin may play a critical role in maintaining the epithelial polarity of these nephron segments.

Relapsing polychondritis is an uncommon disease manifested by episodes of progressive inflammation and destruction of cartilage. While the cause remains unknown, an autoimmune pathogenesis appears likely. Characteristic features include auricular chondritis, arthritis, nasal chondritis, ocular inflammation, respiratory tract involvement and audiovestibular damage. The clinical course of patients may vary from a relatively benign illness free of clinically evident visceral involvement, to one of episodic or smoldering activity with variable intensity, to a f ulminant illness and death within months of diagnosis. Dapsone, corticosteroid and immunosuppressive agent remain the effective therapies. We have experienced a case of relapsing polychondritis and active pulmonary tuberculosis in a 69-year-old man. He suffered from arthralgia and swelling of joints for several months on the first admission and initially was diagnosed as pseudogout based on polyarthritis and chondrocalcinosis of right knee joint. During follow-up, chondritis of both auricles and nose, which was proved by the biosy of right auricle, and relapse of polyarthritis were developed. His spu tum smear for acid-fast bacillus was postive on the second admission. Then he was diagnosed as relapsing polychondritis and active pulmonary tuberculosis and has achieved improvement with medication of dapsone and antituberculosis drugs according to susceptability test during followed-up. Thus we report this case with literature review.

Castleman's disease is a benign disorder characterized by hypervascular lymphoid hyperplasia. The etiology of the disease is still unknown. Although it may occur at the various sites such as peritoneum, retroperitoneum, pelvic lymph node, muscle and lung, it occurs most commonly at the mediastinum. Even though specific pathophysiologic relations are still not clearly determined between two different histologic types -hyaline vascular type and plasma cell type-, there were several previous reports dealing with the plasma cell type transformed or progressed into different types of malignancies such as malignant lymphoma, Kaposi's sarcoma and Hodgkin's disease. We experienced a case of plasma cell type Castleman's disease that transformed into a malignant lymphoma and report this case with review of literatures.

BACKGROUND: Association of arterial stiffness and osteoporosis has been previously reported in women. However, this association is still controversial for men. Therefore, we investigated correlation of arterial stiffness and osteoporosis by measuring brachial-ankle (ba) pulse wave velocity (PWV) and bone mineral density (BMD). METHODS: We reviewed medical charts of 239 people (women: 128, men: 111) who visited the Health Promotion Center, retrospectively. ba-PWV was measured by automatic wave analyzer. Lumbar spine (L1-L4) BMD and femur BMD were measured by dual energy X-ray absorptiometry. Metabolic syndrome was based on the National Cholesterol Education Program (NCEP)-Adult Treatment Panel (ATPIII) definition. Body mass index (BMI)>25 kg/m2 was used instead of waist circumference. RESULTS: In Pearson's correlation analysis, PWV and femur BMD (Neck, total) had a significant inverse relationship in men (r=-0.254, P=0.007; r=-0.202, P=0.034). In women, PWV and the L-spine, femur (Neck, total) had a significant inverse relationship. (r=-0.321, P<0.001; r=-0.189, P=0.032; r=-0.177, P=0.046) Age and PWV showed the greatest association in both men and women (r=0.46 P<0.001; r=0.525, P<0.001) In multiple regression analysis, the L-spine BMD and PWV had an independent relationship in women after adjusting for age, metabolic syndrome, BMI, smoking, drinking and exercise. (r=-0.229, P=0.015). No independent association was found between PWV and BMD in men. CONCLUSIONS: The association between arterial stiffness and BMD was confirmed in women. However, this association was not statistically significant for men.

We present the case of a 5-year-old child with coronary complications due to Kawasaki disease; this patient unintentionally underwent both dual-source computed tomography (DSCT) coronary angiography and invasive coronary angiographic examination in 2 months. This case highlights the strong consistency of the results between DSCT coronary angiography and invasive coronary angiography. Compared to conventional invasive coronary angiography, DSCT coronary angiography offered additional advantages such as minimal invasiveness and less radiation exposure.

Tubuolointerstitial inflammation and tubular injury account for most types of glomerulonephritis. The injury is characterized by an infiltration of mononuclear cells with atrophy and dilation of tubules and increased deposition of collagen in the interstitium. Despite the fact that the degree of tubulointerstitial injury in glomerular diseases may be the best predictor of overall outcome, the pathogenic mechanism by which the tubular injury develops remains unknown. Osteopontin, a highly acidic, phosphorylated, secreted glycoprotein, is up-regulated in renal cortex in many experimental models of tubulointerstitial fibrosis. In this study, we examined the expression of osteopontin in tubulointerstitium in experimental renal failure mouse, FGS/KIST. Mice were assigned three groups and sacrificed at 1 month, 2 months, and 3 months, in each. Proteinuria, GFR, the degree of tubulointerstitial inflammation, tubular atrophy, glomerulosclerosis and osteopontin expression were measured. Three-month-old group showed severely decreased GFR and marked tubulointerstitial inflammation and glomerulosclerosis compared with other groups. The expression of osteopontin increased with the severity of tubulointerstitial injury. These data suggest that osteopontin may act as a chemotactic or adhesive factor in the recruitment of the monocyte/macrophages and have a role in the pathogenesis of the tubulointerstitial injury.
