Paecilomyces sinclairiis (PS) is known as a functional food or human health supplement. However concerns have been raised about its kidney toxicity. This study was performed to investigate the kidney toxicity of PS by 13 week-oral administration to rats. Blood urea nitrogen (BUN), serum creatinine, and kidney damage biomarkers including beta-2-microglobulin (${\beta}2m$), glutathione S-transferase alpha (GST-${\alpha}$), kidney injury molecule 1 (KIM-1), tissue inhibitor of matrix metalloproteinase 1 (TIMP-1), vascular endothelial growth factor (VEGF), calbindin, clusterin, cystatin C, neutrophil gelatinase-associated lipocalin (NGAL) and osteopontin were measured during or after the treatment of PS. BUN, creatinine and kidney damage biomarkers in serum were not changed by PS. However, kidney cell karyomegaly and tubular hypertrophy were observed dose-dependently with higher severity in males. KIM-1, TIMP-1 and osteopontin in kidney and urine were increased dose dependently in male or at the highest dose in female rats. Increased urinary osteopontin by PS was not recovered at 2 weeks of post-exposure in both genders. Cystatin C in kidney was decreased at all treatment groups but inversely increased in urine. The changes in kidney damage biomarkers were more remarkable in male than female rats. These data indicate that the PS may provoke renal cell damage and glomerular filtration dysfunction in rats with histopathological lesions and change of kidney damage biomarkers in kidney or urine. Kidney and urinary KIM-1 and cystatin C were the most marked indicators, while kidney weight, BUN and creatinine and kidney damage biomarkers in serum were not influenced.

Objectives : This study aimed to evaluate the effects of Alismatis Rhizoma Herbal-acupuncture( AR-HA) at $KI_{10}$(Umgok) on nephritis induced by lipopolysaccharide(LPS) in rat. Methods : Rats were injected with LPS to induce nephritis. The rats in $KI_{10}$-AR-HA group were treated with AR-HA, $KI_{10}$-NP group with needle prick, $KI_{10}$-saline group with normal saline injection respectively at $KI_{10}$ three times for a week. Several experimental items were performed including measurements of the numbers of RBC, WBC, neutrophil in blood, the levels of creatinine, $TNF-{\alpha}$, CINC-1 in serum, creatinine, total protein in urine, MPO in kidney. Results : Needle prick stimulation at $KI_{10}$ significantly reduced WBC in blood of LPS-stimulated rats. Saline injection at $KI_{10}$ significantly reduced WBC in blood, $TNF-{\alpha}$ in serum, total protein in urine of LPS-stimulated rats. AR-HA at $KI_{10}$ significantly reduced WBC, neutrophil in blood, $TNF-{\alpha}$, CINC-1 in serum, creatinine, total protein in urine of LPS-stimulated rats. Conclusion : AR-HA at $KI_{10}$ has a therapeutic effect on nephritis in LPS-stimulated rat. There may be a synergism between $KI_{10}$(Umgok) stimulation and AR-HA solution.
Objectives : This study was designed to evaluate the effects of Phaseoli Semen Herbal-acupuncture(PS-HA) at $KI_{10}$ in acute nephritis induced by lipopolysaccharide(LPS) in rat. Methods : The rats were divided into 5 groups, which were control, LPS, PS-HA, NP and saline group. LPS, PS-HA, NP and saline groups were given LPS to induce acute nephritis and control group did not receive LPS. LPS group did not receive any treatment after the onset of acute nephritis. PS-HA, NP and saline group received PS-HA, normal acupuncture, and saline injection at $KI_{10}$ three times per week, respectively. To evaluate the effect of PS-HA at $KI_{10}$, the complete blood count, BUN, creatinine, TNF-${\alpha}$, and CINC-1 in serum were measured. To show its effect on renal function, creatinine, and total protein in urine was measured as well as urine output. The level of myeloperoxidase in renal tissue was quantified and complete histology was done in kidney samples obtained from the rats. Results : PS-HA group showed a significant reduction in the proportion of WBC and neutrophil, serum BUN, TNF-${\alpha}$, and CINC-1 compared to LPS group. Furthermore, a significant increase in urine output and a decrease in urinary creatinine level, MPO in renal tissue, and number of neutrophils at glomerulus was observed in PS-HA group compared to LPS group Conclusions : PS-HA at $KI_{10}$ was shown to have a significantly effect on treating LPS induced acute nephrits. Therefore, future study is needed to further evaluate the clinical usefulness of PS-HA at $KI_{10}$ in treating acute nephritis.
Purpose: To determine the metabolic influence of the traditional Korean diet (K-diet), which has been regarded as a healthy diet, we investigated the profile of urine organic acids that are intermediates of various types of metabolism including energy metabolism. Methods: Ten women aged 50-60 years were recruited and randomly divided into 2 diet groups, K-diet and control diet, the latter of which is a Westernized Korean diet that is commonly consumed by Koreans nowadays. Before and after the 2-week intervention, 46 urine organic acids were determined using LC/MS/MS, along with clinical parameters. Results: The average concentrations of succinate (4.14 ± 0.84 ㎍/mg creatinine vs. 1.49 ± 0.11, p = 0.0346) and hydroxymethylglutarate (3.67 ± 0.36 ㎍/mg creatinine vs. 2.97 ± 0.29, p = 0.0466), both of which are intermediates of energy metabolism, decreased in the K-diet group after the 2-week intervention, but these were not observed in the control diet group. In particular, the average concentration of succinate in the K-diet group was lower than that in the control group (3.33 ± 0.56 ㎍/mg creatinine vs. 1.49 ± 0.11, p = 0.0284) after 2 weeks. The concentrations of two tryptophan metabolites, 5-hydroxyindolacetate (3.72 ± 0.22 ㎍/mg creatinine vs. 3.14 ± 0.21, p = 0.0183) and indican (76.99 ± 8.35 ㎍/mg creatinine vs. 37.89 ± 10.06, p = 0.0205) also decreased only in the K-diet group. After the 2-week intervention, the concentration of kynurenate, another tryptophan metabolite, was lower in the K-diet group than that in the control diet group (3.96 ± 0.51 ㎍/mg creatinine vs. 2.90 ± 0.22, p = 0.0356). Interestingly, the urine level of kynurenate was positively correlated with BMI (r = 0.61424, p = 0.0003) and total cholesterol (r = 0.46979, p = 0.0088), which decreased only in the K-diet group (239.40 ± 15.14 mg/dL vs. 198.20 ± 13.25, p = 0.0163). Conclusion: The K-diet alters the urinary excretion of organic acids involved in energy metabolism and tryptophan metabolism, suggesting the influence of the K-diet on these types of metabolism. Urine organic acids changed by the K-diet may serve as biomarkers in future studies.
The aim of this experiment was to investigate the effects of Aqua-Acupuncture of Yukmijiwangtang(六味地黃湯) and Palmijihwang-tang(八味地黃湯) water extracts applied at the meridian points BL 23(賢兪) and GV 4(命門) to test the renal function in normal rats. The results obtained were as follows; 1. Among the effects of Aqua-Acupuncture of Yukmijihwangtang water extract at the merdian point BL 23 group, there were significant changes in water balance and urine volume over a 1 week period; Both decreasing and decreasing trends were exihibited. Urinary excretion of sodium and free water clearance changed significantly over a 2 week period; Both decreasing and increasing trends were exihibited, Urinary excretion of potassium, chloride and creatinine, plasma renin activity, plasma levels of aldosterone and atrial natriuretic peptide showed no significant differences compared to the contral group. 2. Among the effects of Aqua-Acupuncture of Palmljihwangtang water extract at the merdian point BL 23 group, there were significant changes in water balance and free water clearance over a 2 week period; a decreasing trend. Urinary excretion of creatinine changed significantly over a 2 week period; an increasing trend. Urinary excretion of chloride changed significantly over 1 week period; an increasing trend. The plasma levels of atrial natriuretic peptide changed significantly over 1 and 2 week period; an increasing trend. Urine volume, urinary excretion of sodium and pottasium, plasma renin activity and plasma level of aldosterone showed no significant differences compared to the control group. 3. Among the effects of Aqua-Acupuncture of Yukmijihwangtang water extract at the meridian point GV 4 group, there was significant decrease in water balance over a 2 week period; there was significant decrease in urine volwne and urinary excretion of sodium and creatinine over a 1 week period, followed by an increasing trend after 2 weeks. Urinary excretion of free water clearance demonstrated significant changes over both 1 and 2 week period; both increasing and decreasing trends were exihibited. Urinary excretion of chloride and plasma levels of aldosterone increased significantly over 1 and 2 week period. Plasma levels of atrial natriuretic peptide also decreased significantly. Plasma renin activity showed no significant differences compared to the control group. 4. Among the effects of Aqua-Acupuncture of Palmijihwangtang water extract at the meridian point GV 4 group, water balance and urinary excretion of chloride, plasma levels of aldosterone decreased significantly over both 1 and 2 week period. Urine volume and urinary excretion of pottasium decreased significantly. Urinary excretion of creatinine and urinary excretion of sodium changed significantly over both 1 and 2 week period. Urinary excretion of free water clearance, plasma renin activity and plasma level of atrial natriuretic peptide showed no significant differences compared to the control group. Seeing these results, I come to know that the effects Aqua-Acupuncture of Yukmijihwangtang and Palmijihwangtang water extracts at the meridian point BL 23 and GV 4 have affected the renal function differently. Seeing the results that BL 23 is a meridian point for Aqua-Acupuncture directly related to the kidney, I think, we can use Aqua-Acupuncture of Yuk-mijihwangtang and Palmijihwangtang water extracts to prevent and to treat the diseases related to kidney.
Renal scarring associated with vesico-ureteral reflux(VUR) is one of the major causes of end stage renal failure and renal hypertension in children. Urinary ${\beta}_2$-microglobulin(MG) has been suggested as a potential marker for presence of renal tubular damage. This study was designed to evaluate the significance of random urine ${\beta}_2$-MG as a predictor of presence of vesico-ureteral reflux in children with urinary tract infection(UTI). 57 children with urinary tract infection were studied. Patients were devided into two groups; 35($78.9\%$) children have UTI without VUR and 12($21.1\%$) children have UTI and VUR. Beta2-MG and creatinine in random urine sample was measured to decide the excretion ratio(${\beta}_2$-MG/creatinine). Among the 57 children with UTI, 44 children were confirmed by urine culture study and 13 children suspected by compatible clinical feature. Random urine ${\beta}_2$-MG of VUR group ($2.2{\pm}5.91$ mg/L) were significantly higher than that of simple UTI group($0.19{\pm}0.16mg/L$)(P=0.03). The ${\beta}_2$-MG/creatinine ratio of VUR group($32.41{\pm}25.7$) were significantly higher than that of simple UTI group($3.93{\pm}3.44$)(P=0.007). In conclusion, random urine ${\beta}_2$-MG and excretion ratio deserved early predictor of presence of VUR in children with UTI. And this method was more simple and inexpensive than the method of measuring ${\beta}_2$-MG with 24 hour urine collection, so might be a useful screening test for VUR in children with UTI.

The purpose of this study is to find out the effects of honey-fried Astragali Radix extract on the nephrotoxicity in rats induced by cyclosporin A(CsA). The experimental rats were divided into three groups of ten. The Normal group was given nothing. The Control group was given only saline water every day for 14 days after the subcutaneous IV injection of 50mg/kg in CsA every other day during a period of 14 days. The sample group was administered 4.8mg/200g of Astragali Radix extract daily for 14 days after the subcutaneous IV injection of 50mg/kg in CsA every other day for 14 days. These groups were observed for 14 days. This experimental research focused on measuring the levels of BUN, creatinine, total protein, sodium, potassium, chloride, AST and ALT in the serum and specific gravity and creatinine in the urine. The results were summarized as follows: 1. Changes in serum The levels of BUN, creatinine. AST and ALT in the serum were significantly decreased in the sample group as compared with those of the control group. Total Protein level in the serum was significantly increased in the sample group as compared with that of the control group. Sodium and Potassium levels in the serum in the sample group were a little lower than those of the control group but no significance was noted. The chloride level in the serum in the sample group significantly increased as compared with that of the control group on the 7th day but in the sample group was significantly decreased as compared with that of the control group on the 14th day 2. Changes in urine Urinary specific gravity in the sample group showed significant increase, compared to the control group on the 7th day but were a little higher than that of the control group on the 14th day. Creatinine level in the urine were a little higher than that of the control group but no significance was found. These results suggest that honey-fried Astragali Radix might be effective on the nephrotoxicity in rats caused by CsA.

The aim of this study was to assess the association of vitamin D and urine microalbumin/creatinine (uACR) and obesity. The study subjects were Korean adults 20 years or older (n = 4,948) who participated in the Korea National Health and Nutrition Examination Survey 2012. Analysis of covariance test adjusted for covariates were performed for uACR levels in relation to vitamin D status [vitamin D deficient, 25(OH)D < 10 ng/dL; vitamin D insufficient, 25(OH)D ≥ 10, < 20 ng/dL; vitamin D sufficient, 25(OH)D ≥ 20 ng/dL]. The key study results were as follows: First, in the populations without obesity (BMI < 25 kg/m2), uACR levels were decreased with the increasing of vitamin D status (p < 0.001) after adjusting for relevant variables. Second, in the populations with obesity (BMI ≥ 25 kg/m2), the association between uACR levels and vitamin D status was not significant (p = 0.659). In conclusion, urine microalbumin/creatinine levels were inversely associated with vitamin D status in Korean adults without obesity, but not in Korean adults with obesity.
This study was carried out to investigate the preventive effect of Salviae Miltiorrhizae Radix, Rhei Rhizoma and Carthami Flos combined with Samgijiwhang-Tang(SJTSRC) on streptozotocin(STZ)-induced diabetic nephropathy. Rats were divided into a control group of rats with STZ-induced diabetic nephropathy, a sample group of those given SJTSRC, and a normal group. In the experiment diabetic nephropathy was induced by giving STZ(60mg/kg) to rats via the peritoneum, and effects were assessed with measures of serum creatinine, serum BUN, secretion content of albumin and glucose content of urine, malondialdehyde(MDA) and glutathione(GSH) content in cortex of kidney. When STZ was injected into sample rat, the value of creatinine and BUN increased validly and STZ did damage to the kidney. When applying SJTSRC to sample rats, the value of serum creatinine decreased validly but the value of serum BUN decreased invalidity. It was confirmed that SJTSRC had an effect on recovery after kidney damage and secretion content of albumin increasedafter administration of SJTSRC but there was no change in glucose content of urine compared with the control group. The decrease of secretion of albumin after injection of STZ was taken to mean progressive diabetic nephropathy, and that reversal of that trend after SJTSRC administration showed that kidney function had improved, not through decreasing blood sugar, but through other factors. Results suggest that diabetic nephropathy was induced by STZ, and SJTSRC was effective in restricting the extent of damage to the kidney and halting the progression of diabetic nephropathy with improvement in levels of serum creatinine and albumin secretion. More study is needed, particularity pertaining to anti-oxidative effects in the kidney cortex.
Some effect on the protein metabolism in growing albino rats by feeding on the rice mixed with wheat or barley have been studied. The species of wheat and barley used in this experiment were either 80% polished or nonpolished wheat, barley and naked barley. The growing rats to be examined were fed on 30% wheat or barley mixed with rice diets for 8 weeks. The total nitrogen, creatinine, amino acid nitrogen and urea-nitrogen contents in the liver and the creatinine and urea-nitrogen contents in the urine have been measured. The results obtained are summarized as follows: 1. The total nitrogen contents in the liver and the serum were no remarkable difference by feeding on each mixed diet, compared with the rice diet group. 2. The creatinine contents in the liver of the unpolished wheat and barley mixed diet groups were the similar to that of the rice diet group, but these were higher by feeding on the polished wheat and barley mixed with rice diets. 3. The amino acid nitrogen contents in the liver of the polished naked barley mixed with rice diet groups were the similar to that of the rice diet group, but these were higher by feeding on the other mixed diets than the rice diet. 4. The urea-nitrogen contents in the serum of the polished wheat and naked barley mixed with rice diet groups were higher than that of the rice diet group, but these were significantly lower by feeding on the polished barley mixed with rice diets than the others. 5. The creatinine and the urea-nitrogen contents in the urine of the original wheat and barley mixed with rice diet groups were higher than that of the polished wheat and barley mixed with rice diet groups. In the view of the above results, it could be seen that the protein metabolism was remarkable change according to polish of the wheat and barley.
