Cyclosporine(CsA) is an immunosupressant drug widely used in post-allogeneic organ transplant to reduce the activity of the patient's immune system and so the risk of organ rejection. It has been studied in transplants of skin, heart, kidney, liver, lung, pancreas, bone marrow and small intestine. Initially isolated from a Norwegian soil sample, Both kidney and liver dysfunction are prominent side effects of CsA. The present study was designed to determine the possible protective effect of salidroside(Sal) isolated from the BuOH extract of Acer termentosum Max against oxidative damage in CsA-treated(50 mg/kg, ip) nephrotoxicity rats. Results showed oral administration of methanol and butanol extact of Acer termentosum Max(200 mg/kg, po) significantly reduced activities of marker enzymes(BUN, Creatinine) and LDH activity in serum to CsA induced experimental kidney injured rats. And significantly decrcease of protein amount level in urine and activities of free radical formation enzyme were significantly improved by the treatment of Sal. And significantly decrcease of MDA level in kidney and activities of calalase, glutathione peroxidation and SOD were significantly improved by the treatment of Sal(20 mg/kg, po). But glutathione concentration and glutathione S-transferase actitity was not affected. Results of this study revealed that Sal could afford a significant protection in the alleviation of CsA-induced nephrotoxicity injury.

Objectives: Diabetic nephropathy is the most common cause of end stage renal disease. Transforming growth factor (TGF)-${\beta}1$, type IV collagen, advanced glycation end-products (AGEs), and angiotensin II type 1 receptor (AT1) are the main factors of diabetic nephropathy. We investigated the effects of Prunus on renal function and histopathological changes of diabetic nephropathy rat model induced by unilateral nephrectomy and streptozotocin. Methods: Diabetes was induced in male Sprague-Dawley rats ($290{\pm}10g$) by injecting streptozotocin (55 mg/kg) into the tail vein after unilateral nephrectomy. Rats were divided into 3 groups (n=6): normal, control, and Prunus. After 8 weeks of oral administration of Prunus extract on the Prunus group from 3 days after streptozotocin injection, we checked weight, 24 hrs urine, blood biochemistry and renal tissue to evaluate renal function and histopathological changes by examining parameters including albuminuria, BUN, creatinine, cholesterol, low density lipoprotein (LDL), triglyceride, TGF-${\beta}1$, type IV collagen, AGEs, and AT1. We also measured mRNA expression of TGF-${\beta}1$, type IV collagen, AGEs, and AT1 by Real Time polymerase chain reaction (RT-PCR). Results: Prunus decreased the amount of 24 hrs proteinuria, and inhibited histopathological changes of diabetic nephropathy including the expression and accumulation of TGF-${\beta}1$, type IV collagen and AGEs which could promote development of diabetic nephropathy. Prunus also inhibited mRNA expression of TGF-${\beta}1$, type IV collagen. Conclusions: These findings suggest that Prunus might protect the renal function and inhibit the development of renal injury by regulating factors including TGF-${\beta}1$, type IV collagen, AGEs, except AT1, so Prunus can be used for diabetic patients to prevent the progression of diabetic nephropathy.

Heptaplatin, a new platinum derivative, has several contradicting reports on the nephrotoxicity. Therefore, the aim of this study is to compare the toxicities of heptaplatin-containing regimens in the chemotherapy. This study was performed retrospectively on seventy-seven patients with advanced gastric cancer who did not receive chemotherapy within the last 1 months before taking of heptaplatin- or cisplatin-containing chemotherapy. The 38 patients among total patients was received heptaplatin-containing regimens (26 with SEF regimens: heptaplatin/epirubicin/5-FU, 12 with SF regimens: heptaplatin/5-FU) and the rest 39 patients was received cisplatin-containg regimens (11 with CEF regimens: cisplatin/epirubicin/5-FU, 28 with ELF regimens: epirubicin/leucovorin/5-FU). Before and after the chemotherapy serum creatinine (Scr) and proteinuria were measured by urine stick test in all patient groups. Also Scr was measured a day before the second cycle and did not vary significantly between groups. However Scr on cycle 3 were significantly higher in SEF and SF groups. In case of proteinuria, it was more frequent on cycle 1 in heptaplatin/5-FU group. Proteinuria before and after on cycle 2 was not different between the two cisplatin -containing groups, but was more frequent in heptaplatin-containing groups. The reason why the Scr measured was not so different could be because we excluded the patients who received only one cycle of heptaplatin and changed the regimen due to signs of nephrotoxcity. As the results nephrotoxicity such as protienuria was appeared to be more frequent with heptaplatin-treated patients. It suggests that the clinical consequences of the toxicity need to further evaluation and also the modalities to prevent or minimize nephrotoxicity of heptaplatin should be studied for future utilization of the drug.

Objectives: Smoking is known to be associated with nephropathy in patients with diabetes. The distinct effects of smoking before and after diabetes has been diagnosed, however, are not well characterized. We evaluated the association of cigarette smoking before and after a diagnosis of diabetes with the presence of diabetic nephropathy. Methods: We analyzed data from the 2011-2013 editions of the Korea National Health and Nutrition Examination Survey. A total of 629 male patients diagnosed with diabetes were classified as non-smokers (90 patients), former smokers (225 patients), or continuing smokers (314 patients). A "former smoker" was a patient who smoked only before receiving his diagnosis of diabetes. A "continuing smoker" was a patient who smoked at any time after his diabetes had been diagnosed. Diabetic nephropathy was defined as the presence of albuminuria (spot urine albumin/creatinine ratio ${\geq}30mg/g$) or low estimated glomerular filtration rate ($<60mL/min/1.73m^2$). Multiple logistic regression models were used to assess the independent association after adjusting for age, duration of diabetes, hemoglobin A1c, body mass index, systolic blood pressure, medication for hypertension, and medication for dyslipidemia. Female patients were excluded from the study due to the small proportion of females in the survey who smoked. Results: Compared to non-smokers, continuing smokers had significantly higher odds ratio ([OR], 2.17; 95% confidence interval [CI], 1.23 to 3.83) of suffering from diabetic nephropathy. The corresponding OR (95% CI) for former smokers was 1.26 (0.70 to 2.29). Conclusions: Smoking after diagnosis of diabetes is significantly associated with the presence of diabetic nephropathy in the Korean male population.

The purpose of this study was to assess calcium and sodium intakes and urinary excretion of adults in Busan and to evaluate the relationship between urinary calcium excretion (UCa) and the status of anthropometric, blood pressure, urine analysis, and nutrient intake of subjects. Nutrient intake by 24 hr recall, 24 hr urinary calcium and sodium excretion (UNa) were measured with 87 adults aged 20-59 yrs (42 men and 45 women). The mean calcium intake was 88.0% for men and 103.0% for women of Recommended Intake. The mean sodium intake was 283.4% for men and 250.5% for women of Adequate Intake (AI). The mean 24hr UCa was 127.4 mg in men and 107.3 mg in women. The mean 24 hr UNa was 3650.6mg in men and 3276.4mg in women. The intake and urinary excretion of calcium and sodium were not significantly different by gender. UCa showed significantly positive correlations with sodium intake and UNa in men (p < 0.001, p < 0.05) and women (p < 0.001, p < 0.001) and with age, systolic blood pressure (SBP) and sodium density in women (p < 0.05, p < 0.05, p<0.01). The UCa/creatinine showed significantly positive correlations with age, sodium intake, sodium density, and UNa in women (p < 0.05, p < 0.01, p < 0.01, p < 0.01). When UCa was stratified into quartile (Q1-Q4), age, SBP, UCa, UNa, sodium intake, and AI percentage of sodium (p < 0.01, p < 0.05, p < 0.001, p < 0.001, p < 0.001, p < 0.001) were significantly higher in Q4. The mean intake and AI percentage of sodium in Q4 were 4768.8mg and 329.0. Based on the results, UCa was related to age, SBP, UNa, and sodium intake. Therefore, nutritional education of decreasing sodium intake for decreasing UCa is needed.

This study was designed to investigate the effects of dietary calcium. serum estrogen level and physical activity on the bone status of 116 healthy elderly women living in urban area. Current calcium intake was assessed by convenient method(refered to as Ca intake) and calcium containing food frequency method(refered to as Ca index) Daily activity record was used for the estimation of physical activity level, and serum estrogen level was measured from fasting blood of subjects. The rate of bone resorption was evaluated by the determination of hydroxyproline(Hpr) in fasting urine with correction for creatinine excretion. The results of this study are summarized as follows : 1) Average daily Ca intake of subjects was 621.4$\pm$155.8mg, which is above the Korean recommended dietary allowances. However 44.8% of the subjects consumed Ca below RDA level. Ca index score was significantly correlated with the bone status(P<0.05), Ca intake did not show significant correlation with the bone status although a positive trend of influence was evident. 2) Average serum estrogen level of subjects was 18.7$\pm$9.8pg Contrary to our anticipation. estrogen level did not show any significant relation to age and bone status. 3) Daily physical activity was classified into four categories by activity intensity : sedentary. moderate, active and severe. The average physical activity of subjects belong to moderate level. and the bone status was significantly related to the physical activity(P<0.01) 4) Among other influential factors such as age, pocket-money. family type. drinking, smoking and BMI, there was a significant difference between bone status and BMI(P<0.05). 5) Multiple regression analysis of variables showed that physical activity has greater effect than other variables when the entire subjects were taken into account. However. eliminating the subjects whose bone status rated as excellent(Hpr/cr<0.009), Ca index showed higher correlation than physical activity. These results have demonstrated that dietary calcium intake is the primary important factor for keeping good bone health and that bone status of subjects with a sufficient calcium intake is affected by various factors such as physical activity, age, smoking. BMI and others.

In order to determine the effect of Oryeongsan reputed to have diuretic action since Han Dynasty and possible synergetic action of Dianthi Semen, Polygonum avicularis Herba, Kochiae Fructus and Akebiae Lignum, herbs with similar reputation, when added to the above prescription, their decoction powders were solved into distilled water and injected into rabbits through the ear vein. Upon the treatment, the excretion of sodium, potassium and chloride ion together with urine volume was kinetically determined. At the same time the clearance of plasma creatinine and sodium ion was determined and the following results were obtained. Every experimental group demonstrated diuretic action, though feable, of relatively long duration. The diuretic mechanism in the case of Oryeongsan made up by mixing the seperate extracts of individual components and Oryeongsan(A) plus Dianthi Semen was found to be inhibitory effect of renal tubular reabsorption in contrast to the case of Oryeongsan(A) plus Polygonum avicularis Herba, Kochiae Fructus or Akebiae Lignum in which case the diuretic mechanism was found to be glomerular vascular dilatation. The urinary excretion of potassium ion was increased in the case of Oryeongsan(A) plus Dianthi Semen, Kochiae Fructus of Akebiae Lignum whereas in the other cases no similar change was registered. The diuretic action was most remarkable in the case of Oryeongsan(A) plus Polygonum avicularis Herba followed by Oryeongsan(A) plus Kochiae Fructus, Oryeongsan(A) plus Dianthi Semen, extract mixture of individual component of Oryeongsan, Oryeongsan(A) and Oryeongsan(A) plus Akebiae Lignum decreasing order. The duration of diuretic action was found to be 90 minutes in the case of Oryeongsan and mixture of individual component of Oryeongsan, and 60 minutes in the case of Oryeongsan(A) plus Dianthi Semen, Kochiae Fructus or Akebiae Lignum in contrast to the case of Oryeongsan(A) plus Polygonum avicularis Herba which lasted up to 120 minutes.

This study explored the effects of dietary calcium level and Hijikia fusiforme supplementation on bone indices and serum lipid levels using 36 female Sprague-Dawley rats as a model. Rats received low Ca diet for 3 weeks after ovariectomy. The rats were then divided into six dietary groups and fed low (0.1% Ca), normal (0.5% Ca) and high (1.5% Ca) Ca diets (CaL, CaN, CaH) and low, normal, high Ca diets with Hijikia fusiforme supplementation (CaLH, CaNH, CaHH) for 3 weeks. After each experimental periods, 24 hour urine and/or blood samples, left and right femurs were collected for analysis. Serum Ca concentration showed no significant difference by dietary Ca levels and Hijikia fusiforme supplementation. Alkaline phosphatase activity was significantly higher in normal and high Ca group compared to low Ca group. Serum total cholesterol, triglyceride and total lipid were not significantly different among groups. HDL-cholesterol showed no significant difference by Hijikia fusiforme supplementation. However, the normal and high Ca groups showed significantly higher HDL-cholesterol compared to the low Ca group. Urinary hydroxyproline and hydroxyproline/creatinine ratio were not significantly different among groups. The wet weight of the femur was significantly higher in low Ca group compared to normal or high Ca group. The dry weight, wet weight/body weight, length and breaking force of the femur were not significantly different among groups. Ash contents/wet weight of the femur was significantly increased as dietary Ca levels up and significantly higher in Hijikia fusiforme supplementation groups. The Ca content of the femur were significantly higher in the normal and high Ca groups than the low Ca group. However, there was no significant difference in Ca content by Hijikia fusiforme supplementation.
