Objectives : The purpose of this study is to investigate the effects of Pyrrosiae Herba herbal-acupuncture(PH-HA) at $KI_{10}$(Umgok) on nephritis induced by lipopolysaccharide(LPS) in rats. Methods : Rats were assigned to four groups: normal, LPS, saline and PH-HA. Rats in the saline and PH-HA groups were treated with saline injection and PH-HA respectively at $KI_{10}$, three times over the period of one week. All animals, except those in the normal group, were injected intra-peritoneally with LPS to induce nephritis. WBC, in blood, tumor necrosis factor alpha(TNF-${\alpha}$), cytokine-induced neutrophil chemoattractant 1(CINC-1), blood urea nitrogen(BUN), creatinine in serum, urinal volume, total protein creatinine in urine, and renal myeloperoxidase (MPO) were analyzed. Results : 1. PH-HA group showed significantly reduced levels of serum BUN, serum creatinine, TNF-${\alpha}$, and CINC-1 compared to the LPS group. Furthermore, a significant increase in urine output and more significant decreases in total protein in urine and MPO in renal tissue were observed in the PH-HA group when compared to the LPS group. 2. The PH-HA group showed significantly reduced levels of serum creatinine and renal MPO, and a more significant increase in urine output compared to the saline group. Conclusions : According to these results, it is postulated that PH-HA at $KI_{10}$ has anti-inflammatory and renal-protective effects on LPS-induced nephritis in rats, and both acupoint $KI_{10}$ and the herb Pyrrosiae Herba made contributions to these effects. Further studies on the interaction between acupoint $KI_{10}$ and the herb Pyrrosiae Herba may be needed.

To evaluate the renal toxicity of the antitumor agent, 5-(piperidonomethylphenyl)-2,3-dihydroimidazo[2,1-a]isoquinoline (SDZ-62-434), rats were treated with SDZ-62-434 of 50 mg/Kg, i.p., once and 10 mg/Kg, i.p., daily for 7 days. The kidney weights and urine volume after and during the treatment were observed. The concentrations of urinary creatinine, protein, and the activities of N-acetyl-$\beta $D-glucosaminidase (NAG), alanine aminopeptidase (AAP), $\gamma$-glutamyl transpeptidase (GGT) and lactate dehydrogenase (LDH) in 24 hr urine were also determined. The kidney weights after acute and subacute administration was not affected. The urine excretions were increased 5 days after the acute administration and increased after the daily 3rd day-administration. The excretion of creatinine was similar as that of urine excretion. The excretion of creatinine was increased 5 days after the acute and subacute administration. However, the protein excretion didn't changed in both treatment. Those indicate that SDZ-62-434 might induce the diuresis and also suggest that diuresis might be due to the some metabolites rather than the compound itself. The urinary activities of NAG and LDH were not affected after the acute treatment. However, the urinary activities of AAP and GGT were slightly increased 3 days after the acute administration but, returned to the control value. In subacute treatment, the activities of GGT was not changed. And the activities of NAG were declined after the 7th day-administration. However, the activities of AAP were significantly increased after the 5th day-administration. Furthermore, the urinary activities of LDH were continuously increased during the subacute administration. These results indicate that the high and subacute administration might induce a weak damage on the kidney cells. Furtherrnore, the present results suggest that SDZ-62-434 might have relatively slow-emerging and mild toxicity to the kidney.

The purpose of this study firstly was conducted to establish a radioimmunoassay (RIA) of estrone sulfate ($E_1S$), secondly to monitor the reproductive status of dairy cows using their urine samples. Urine and blood samples were collected in series within a day from four pregnant Holstein-friesian cows to evaluate the relationship between $E_1S$ levels in blood and urine with or without urinary creatinine basis. The urine was then collected biweekly from three cows in estrous and those artificially inseminated; collection from pregnant cows was made on a monthly basis. Results indicated that sensitivity for the $E_1S$ RIA was 5 pg/tube and the recovery rate was 100%. The daily urinary creatinine concentrations fluctuated within a day, but changes were slighter in midday, whereas the changes of concentrations of $E_1S$ in urine were relatively smaller. The concentrations of serum $E_1S$ during the estrous cycle were undetectable due to the limitation of assay, but the urinary $E_1S$ level could be measured with no obvious changes during the cycle. The urinary $E_1S$ levels increased remarkably around 7.7 to 8.3 ng/ml, 80 to 100 days after pregnancy but the serum $E_1S$ levels did not elevate until 120 to 150 days. The level of $E_1S$ increased gradually during pregnancy and eventually reached its peak before parturition at around 40 ng/ml and finally decreased to its basal level 2 days postparturition. During pregnancy, $E_1S$ concentrations of urine increased earlier than those in blood. The correlation coefficients between urinary and serum $E_1S$ concentration during pregnancy and postparturm were higher than those adjusted with creatinine (creatinine ratio). The concentrations of $E_1S$ in urine could be maintained unchanged for 8 days storing the samples in room temperature, which was extended to 8 days when the samples were pretreated by boiling for 30 minutes or treated with autoclave. In conclusion urinary $E_1S$ concentrations can be used directly for monitoring the pregnant status and fetal viability of dairy cows and can assist accurate confirmation of pregnancy in cows at least 80 to 100 days after insemination much earlier than by serum $E_1S$.

Background: There are concerns about the health effects of various environmental pollution exposures among residents living near coal-fired power plants (CFPP). Objectives: This study attempted to compare the concentrations of heavy metals in blood and urine and those of urinary volatile organic compound (VOC) metabolites according to the residential separation distance. Methods: Participants in the study totaled 334 people who have lived for more than 10 years in areas within 10 km of a CFPP. The separation distance was analyzed in quartiles by dividing it into Q1 (88 people), Q2 (89 people), Q3 (89 people), and Q4 (68 people). We explained the purpose of this study to the participants and collected blood and urine after obtaining signatures on a participation agreement. Results: The study participants were 102 males (30.5%) and 232 females (69.5%), with an average age of 71. The average length of residence and distance were 43.8 years and 4,800 meters. The geometric mean concentrations of Pb, Cd, and Hg in blood and As and Cd in urine were respective 1.35 ㎍/dL, 1.43 ㎍/L, 3.16 ㎍/L. They were 167.88 ㎍/g for creatinine and 1.58 ㎍/g creatinine. The metabolite concentrations of VOCs were 50.67 ㎍/g creatinine in t, t-muconic acid (t, t-MA), 10.73 ㎍/g creatinine in benzyl mercapturic acid, 317.05 ㎍/g creatinine in phenylglyoxylic acid, 123.55 ㎍/g creatinine in methylhippuric acid, and 190.82 ㎍/g creatinine in mandelic acid. The concentration of Pb in the blood and Cd and t, t-MA in the urine of residents within affected area of the CFPP showed statistically significant differences among distance groups. Conclusions: The concentration of urinary VOCs metabolites, especially t, t-MA, differed according to the distance groups of residents within the affected area of CFPP (p<0.05).

This study investigated the preventive effect of Saururus chinensis Baill against renal damage induced by a high-fructose diet in rats. The rats (n = 30) were fed either a cornstarch-based (65%), high-fructose (65%), or high-fructose (64.5%) diet with 0.5% S. chinensis Baill extract for 10 weeks. Twenty-four hour urine collections were obtained and the animals were sacrificed after an overnight fast. Serum urea and creatinine and urine albumin were measured using colorimetric methods, and creatinine clearance was determined. In addition, thiobarbituric acid reactive substances (TBARS), reduced glutathione (GSH), and the activity of superoxide dismutase (SOD) in the kidney were determined. Kidney samples were also examined histologically. The fructose-fed rats showed renal dysfunction, indicated by decreased creatinine clearance, increased albumin in the urine, and increased urea and creatinine in the serum. These renal function parameters were comparable to control levels in rats that consumed S. chinensis Baill. Fructose consumption increased renal TBARS and reduced GSH and SOD activity, whereas these levels were near-normal in the rats consuming S. chinensis Baill The kidneys of fructose-fed rats showed glomerular basement membrane thickening, mesangial matrix expansion, and tubule dilation. These pathological changes were not seen in the rats that consumed S. chinensis Baill. Therefore, S. chinensis Baill effectively alleviated fructose-induced renal damage in these rats, at least partially due to antioxidant activity.

The purpose of the present study was to investigate the effectiveness of silver spike point (SSP) low frequency electrical stimulation on glomerular filtration rate (GFR), specifically, such as diuretic action in 24 hour urine and in plasma analysis from normal volunteer. The current of 1 Hz continue type (CT) of SSP low frequency electrical stimulation significantly decreased in plasma creatine from normal volunteer. However, the urine creatinine clearance (Ccr) was significantly increased by SSP low frequency electrical stimulation in normal volunteer. These results suggest that the SSP low frequency electrical stimulation, especially current of 1 Hz continue type, significantly regulates urine creatinine clearance and glomerular filtration rate from normal volunteer. Therefore, the SSP low frequency electrical stimulation is a good regulator through a diuretic action of hypertension.

Toluene in air and blood and hippuric acid in urine were checked for the 41 female workers who are exposed to toluene and have normal liver function in shoe making factories in July, 1993. Toluene in air was sampled with charcoal by personal air sampler at least 4 times and analyzed by gas chromatography. At the end of shift, blood and spot urine were collected with a vacuum tube containing EDTA and a polyethylene bottle for detecting blood toluene and urine hippuric acid and analyzed by gas chromatography and high performance liquid chromatography. Means of air and blood toluene and urine hippuric acid concentrations were 34.35ppm, 0.360mg/L, and 1.78g/g creatinine, respectively. Toluene in air showed a good correlation with hippuric acid in urine(r=0.4503) and toluene in blood(r=0.4596). The hippuric acid in urine and toluene in blood corresponded 10 exposure of 100ppm toluene in air were 2.628g/g creatinine and 0.481mg/L. Blood toluene and urine hippuric acid expected ratio were not correlated to the obesity index and working duration, however increased with age.

Diabetic Nephropathy is one of the major causes of chronic renal failure. It is a common microvascular complication and clinically defined as the presence of persistent Proteinuria. We studied the effects and change of the renal function of Complex Herbal medication of the 20Diabetic Nephropathy patients. We measured the initial levels of Total Protein, Creatinine Clearance Rate(Ccr), Serum Creatinine(Serum-Cr), Urine Creatinine(Urine-Cr) and HbA1C on admission and followed up the level changes of Total Protein, Ccr, Serum-Cr and Urine-Cr on discharge. The results are following : Complex Herbal Medication does not cause the renal toxicity. The longer hypertension period is, the higher Serum-Cr level and Urine-Cr level. In an older age group, Urine-Cr is lower. 4.From the 'Deficiency in Origin and Excess in Superficiality(本虛表實)'points of view, Complex Herbal Medication improves the Serum-Cr in Diabetic Nephropathy patients. According to this results, it could be suggested that Complex Herbal Medication does not cause the renal toxicity in Diabetic Nephropathy patients and intensive controls of blood sugar, blood pressure and Complex Herbal Medication prevent the renal failure in Diabetic Nephropathy patients with early stage of Microalbumiuria.
