The kidney is one of the main organs affected by lead toxicity. We investigated the effects of berberine on lead-induced nephrotoxicity in adult male Wistar rats. Animals received an aqueous solution of lead acetate (500 mg Pb/L in the drinking water) and/or berberine (50 mg/kg, i.g.) for 8 weeks. Lead caused an increase in malondialdehyde (P < 0.001) and total oxidant status (P < 0.01), and a decrease in reduced glutathione (P < 0.001), catalase (P < 0.01), superoxide dismutase (P < 0...

BACKGROUND: The high consumption of fat and sugar contributes to the development of obesity and co-morbidities, such as diabetes, and cardiovascular and kidney diseases. Different strategies have been used to prevent these diseases associated with obesity, such as changes in eating habits and/or the addition of dietary components with anti-inflammatory and anti-oxidant properties, such as gamma-oryzanol (γOz) present mainly in bran layers and rice germ. METHODS: Animals were randomly divided into four experimental groups and fed ad libitum for 20 weeks with control diet (C, n = 8), control diet + γOz (C + γOz, n = 8), high-sugar and high-fat diet (HSF, n = 8), and high-sugar and high-fat diet + γOz (HSF + γOz, n = 8)...

Hereditary mutations in Tamm-Horsfall protein (THP/uromodulin) gene cause autosomal dominant kidney diseases characterized by juvenile-onset hyperuricemia, gout and progressive kidney failure, although the disease pathogenesis remains unclear. Here we show that targeted expression in transgenic mice of a mutation within the domain of 8 cysteines of THP in kidneys' thick ascending limb (TAL) caused unfolded protein response in younger (1-month old) mice and apoptosis in older (12-month old) mice. While the young mice had urine concentration defects and polyuria, such defects progressively reversed in the older mice to marked oliguria, highly concentrated urine, fibrotic kidneys and reduced creatinine clearance...

BACKGROUND: High altitude renal syndrome has been described in populations with excessive erythrocytosis. We evaluated whether high altitude (HA) dwellers might be at increased risk for kidney disease. METHODS: We performed a cross-sectional study to investigate differences in prevalence of kidney function and metabolic syndrome in healthy subjects living at HA vs. sea level (SL) without any known history of hypertension, diabetes or chronic kidney disease. RESULTS: We examined 293 subjects, aged 40 to 60 years: 125 SL (154 m) and 168 HA (3640 m) dwellers...

Uric acid nephropathy (UAN) is caused by excessive uric acid, and is a key risk factor for uric acid nephrolithiasis, gouty arthritis, renal diseases and cardiovascular diseases. The present study aimed to evaluate the protective effect of fucoidan, a sulfated polysaccharide component of brown algae, on UAN and to elucidate the underlying molecular mechanism. A rat model of UAN was induced by adenine treatment, and rats were then randomly assigned to control, model or fucoidan treatment groups. Hematoxylin and eosin staining of the kidney tissues of rats with UAN was subjected to conventional morphological evaluation...

Although 85% of patients with univentricular heart after Fontan procedure survive twenty years after operation, the procedure alone seems to be an inadequate treatment as a permanent clinical solution. Patients with a "Fontan physiology" additionally have to face a various extra-cardiac complications, including thyroid, liver and kidney dysfunction, which are not only potentially life-threatening, but also can potentiate the circulatory insufficiency. AIM: The aim of the study was to assess a multiorgan dysfunction in adult patients after Fontan operation in long term follow-up and compare to healthy controls...

Gout is a multifactorial disease characterized by acute inflammatory arthritis, and it is caused as a consequence of hyperuricemia. A recent meta-analysis of genome-wide association studies has newly identified the relationship between serum uric acid (SUA) levels and rs889472, a single nucleotide polymorphism of musculoaponeurotic fibrosarcoma oncogene (MAF/c-MAF). However, it remained unclear whether rs889472 is associated with gout susceptibility. In the present study, we investigate the association between c-MAF rs889472 and gout in Japanese male population...
