Objectives: The present study was carried out to investigate the preventive effects of Samgijiwhang-Tang(SJT) on streptozotocin(STZ)-induced diabetic nephropathy. Methods: SIT was given to rats through oral administration. The experimental animals were divided into a normal group of rats, a control group of STZ-induced diabetic rats, and a sample group with SIT administration. Rehmanniae Radix Preparat is combined in the original prescription of SIT, but in this experiment, Rehmanniae Radix was combined instead of Rehmanniae Radix Preparat to compare the effects of anti-diabetic nephropathy. Experimental diabetic nephropathy was induced by the injection of STZ(60mg/kg) in the rat via the peritoneum. The effect of SIT on STZ-induced diabetic nephropathy was observed by measuring the serum level of creatinine and BUN, in addition to urine secretion of albumin for 24 hours and the level of glucose found in the urine. Anti-oxidative stress of SIT administration in a living body was estimated by measuring lipid peroxide and GSH content in the cortex of kidneys. Results: STZ induced an increase of serum creatinine, urine glucose and renal cortical lipid peroxidation was lowered by Rehmanniae Radix Preparat combined SIT administration. Conclusions: The SIT treatment showed a protective effect on the rat diabetic nephropathy model, and action mechanism of the effect was thought to be concerned with anti-oxidative stress.

Objectives : This study aimed to evaluate the effects of Stephaniae tetrandrae Radix Herbal-acupuncture(SR-HA) at KI10(Umgok) on nephritis induced by lipopolysaccharide(LPS) in rats. Methods : Male SD rats (n=32) were allocated to four groups; normal, LPS, saline, and SR-HA. The rats in the LPS, saline, and SR-HA groups were injected intra-peritoneally with LPS (2 mg/kg) to induce nephritis. The rats in the saline and SR-HA groups were treated with saline injection and SR-HA respectively at KI10 three times a week. To evaluate the effects of SR-HA at KI10 on nephritis in rats, the authors evaluated the numbers of WBC and neutrophils in blood, and the levels of creatinine, TNF-${\alpha}$, CINC-1 in serum, creatinine, total protein in urine and renal MPO. Results : SR-HA at KI10 significantly inhibited the increase of WBC and neutrophils in blood, TNF-${\alpha}$, CINC-1 in serum, creatine, total protein in urine and MPO in kidney of LPS-stimulated rats. Conclusions : SR-HA at KI10 may have therapeutic effects on nephritis in LPS-stimulated rats.

Comparative blood analysis was carried out to investigate the change of blood constituent in TAE-EUM-IN group and control group. RBC, WBC, hemoglobin, hematocrit, total protein, triglyceride, phospholipid, total cholesterol, LDL-cholesterol, HDL-cholesterol, BUN, creatinine, ACTH, cortisol and prostaglandin E and $F_2{\alpha}$ were measured. And the following results were obtained: 1. In the change of blood cell, the value of hematocrit showed significant difference, while that of RBC, WBC and himoglobin didn't. 2. In the change of protein, the value of total protein showed significant difference, but that of albumin didn't. 3. In the change of lipid and cholesterol in serum, the value of triglyceride, phospholipid, total cholesterol and LDL-cholesterol indicated significant difference, while that of HDL-cholesterol indicated significant difference, while that of HDL-cholesterol didn't. 4. The value of BUN in serum represented significant difference, but that of creatinine didn't. 5. The value of cortisol in plasma showed significant difference, but that of ACTH didn't. 6. The value of prostaglandin E and $F_2{\alpha}$ in plasma showed significant difference. These results suggest that investigation on hormones and blood constituents enables objectification in differentiation of four types of physical constitution.

Objectives : The present study was carried out to investigate the beneficial effect of Coicis Semen extract(CSe) on streptozotocin(STZ)-induced diabetic nephropathy rats. CSe was given to rats with oral administration. Methods : The experimental animals were divided into 3 groups : normal group of rats, control group of STZ-induced diabetic rats, sample group with CSe treatment. Experimental diabetes was induced by the injection of STZ(60 mg/kg) to the rat via the peritoneum. The effects of CSe on STZ-induced diabetic nephropathy were observed by measuring the serum level of creatinine, BUN and uric level of glucose. Kidney level of lipid peroxidation and the activities of reduced glutathione(GSH) were also examined Results : STZ-induced increase of serum creatinine was lowered by CSe treatment, but BUN and uric level of glucose did not show significant changes. CSe oral administration showed statistical decrease of lipid peroxidation in renal cortical tissues, but it has no effect on the activities of GSH. Conclusion : CSe treatment showed protective effect on rat diabetic nephropathy model, but action mechanism of the effect was still not dear. We thought to be concerned with anti-oxidative stress.

Clerodendrum trichotomum is a folk medicine exhibiting anti-hypertension, anti-arthritis, and anti-rheumatism properties. However, little is known about whether the material might prevent hyperuricemia and associated inflammation. In this study, we explored whether C. trichotomum leaf extract (CTE) prevented hyperuricemia induced by potassium oxonate (PO) in mice. CTE (400 mg/kg body weight) significantly reduced the serum uric acid (UA), blood urea nitrogen (BUN), and serum creatinine levels and increased urine UA and creatinine levels. CTE ameliorated PO-induced inflammation and apoptosis by reducing the levels of relevant proteins in kidney tissues. Also, CTE ameliorated both UA-induced inflammatory response in RAW 263.7 cells and UA-induced cytotoxicity in HK-2 cells. In addition, liver transcriptome analysis showed that CTE enriched mainly the genes for mediating positive regulation of MAPK cascade and apoptotic signaling pathways. Together, the results show that CTE effectively prevents hyperuricemia and associated inflammation in PO-induced mice.

Objectives : This study was carried out to research the protective effects of Sagunja-Tang(SA) through in vivo experiments, and tried to investigate the relation between oxidation of renal tissues and deficiency of Qi. Methods : Acute renal injury which initiated from free radical induced by $HgCl_2$, were applied to mice and metabolic data were obtained. In order to measure the degree of renal injury, serum level of creatinine, blood urea nitrogen(BUN), total protein(TP) and glucose were measured. Besides, serum level of alanine aminotransferase(AST), aspartate aminotransferase(ALT) were measure too. Lipid peroxidation of renal cortex was examined by measuring malondialdehyde(MDA), a product of lipid peroxidation. Results : SA had protective effects on acute renal injury caused by decrease of glomerular filtration which was initiated by subcutaneous injection of $HgCl_2$. SA protected acute liver injury too. Conclusions : Through this study, we found that SA have healing effects on renal injury of $HgCl_2$ induced oxidative stress that is similar to deficiency of Qi. And further studies have to be followed to certify the mechanisms.

This study was undertaken to determine if Plantaginis Semen Herbal Acupuncture(PSA) has a protective effect against glycerol-induced acute renal failure in rats. Rats were dehydrated for 24hr and then injected with 8 ml/kg of $50\%$ glycerol, one-half of dose in each hindlimb muscle. In experiments for PSA effect, rats received 0.1 ml of PSA extraction in both sides of corresponding Shenso($BL_{23}$) of human body for 3 days after injection of glycerol. The experimental group were di vided into the Normal group, the Control group, the PSA group. Glycerol injection decreased glomerular filtration rate and increased urine volume, serum creatinine, BUN level and fractional excretion of glucose, $Na^+$, $K^+$ and $CI^-$. These result show that glycerol injection result in acute renal failure. PSA significantly increased glomerular filtration rate and significantly decreased serum creatinine, BUN level and fractional excretion of glucose, $Na^+$ and $CI^-$ as compared Control group. This suggests that PSA could be used in prevention and treatment of acute renalfailure. However, the precise mechanisms of PSA protection remain to be determined.

The pharmacokinetics of atenolol (25 mg/kg, i.v.) in the folate-induced renal failure rabbits was studied. Renal failure was induced by the i.v. injection of folate (50, 100, and 200 mg/kg). At folate dose of 100 and 200 mg/kg, the serum creatinine concentration (Scr) and blood urea nitrogen (BUN) increased significantly compared with control rabbits. Plasma concentrations and AUC of atenolol increased significantly at folate dose of 100 and 200 mg/kg. The elimination rate constant $(K_{el})$ and total body clearance $(CL_t)$ of atenolol decreased significantly, and half-life ($t_{1/2}$) and mean residence time (MRT) of atenolol increased significantly at folate dose of 100 and 200 mg/kg. The serum creatinine concentration $(S_{cr})$ correlated well (p<0.05) with half-life $(t_{1/2})$ and elimination rate constant $(K_{el})$ of atenolol, as well as BUN with AUC and total body clearance $(CL_t)$ of atenolol.

A retrospective study of 737 consecutive patients surviving the first 24 hours who underwent valve replacement surgery from July 1980 to June 1993 was undertaken to determine the prevalence, variables that could be used to predict outcome and results of therapy for postoperative acute renal failure[ARF]. Twenty-one patients[2.8 %] developed acute renal failure. Positive risk factors noted in the development of postoperative renal failure included age, New York Heart Association class III & IV, endocarditis and elevated preoperative concentration of serum creatinine. The duration of cardiopulmonary bypass, aortic cross-clamping and the total duration of the operation also closely correlated with the incidence of ARF. The mortality rate for established ARF was 38.1% and ARF was associated with a significant increase in the length of hospitalization, ventilator support and intensive care unit stay. The incidence and mortality rate of oliguric renal failure was 38.1% and 85.7%. The highest mortality rate was associated with two or more postoperative complications and serum creatinine value exceeded 5 mg/dl. We concluded that therapy should be aimed at prevention of oliguric renal failure, or at least its conversion to nonoliguric renal failure, and early institution of renal replacement therapy with intensive support probably gives the best chance for survival.
