The pharmacokinetics of norfloxacin (100 mg/kg, oral) in renal failure rabbits was studied. Renal failure rabbits were induced by the i.v. injection of folate (50,100 and 150 mg/kg). These produced significant increases of serum creatinine concentration $(S_{cr})$ and blood urea nitrogen (BUN). Plasma concentration and AUC of norfloxacin significantly increased. Elimination rate constant $(K_{el})$ of norfloxacin significantly decreased, and half-life $(t_{1/2})$ of norfloxacin significantly increased. Correlation between serum creatinine concentration $(S_{cr})$ and half-life $(t_{1/2})$ of norfloxacin, and correlation between BUN and AUC of norfloxacin have linear relationship respectively. These results suggest that adjustment or the dosage regimen of norfloxacin is desirable, and serum creatinine concentration $(S_{cr})$ as well as BUN can be used an index for adjusting the dosage regimen of norfloxacin in renal failure.

In an attempt to define the early biochemical determinants that participate in the pathogenesis of glycerol-induced nephrotoxicity, especially focusing on oxygen free radicals, we studied malondialdehyde (MDA) level and the activities of catalase and superoxide dismutase in the renal cortex of rats, and the concentrations of blood urea nitrogen(BUH) and serum creatinine of rats at 24hr after the injection of a 50% solution of glycerol. Sprague-Dawley albino rats weighing 240 to 260 mg were injected intramuscularly with a 50% solution of glycerol(2 mι/kg, 4 mι/kg and 8 mι/kg). The group treated with glycerol showed significantlv higher MDA level and catalase activity, lower SOD activity and higher BUN and serum creatinine concentrations at 24 hr after the injection as compared to those of control group. These results suggest that the excessive oxygen free radicals resulting from the depression of SOD activity is an important determinant in the pathogenesis of glycerol-induced nephrotoxicity.

The effects of Geumguesingitang and Dohongsamultang on rats with nephrosis induced by a single tail-intravenous injection of puromycin aminonucleoside(PAN), 2.5mg/l00g of body weight were evaluated in the present study. The effects of Geumguesingitang and Dohongsamultang on PAN nephrosis were evaluated by measuring (1)the concentrations of albumin, total protein, total lipid, cholesterol, triglyceride, creatinine, blood urea nitrogen(BUN) and uric acid in the serum, (2)the concentrations of protein, creatinine, glucose, occult blood and volume of the 24 hours urine and (3)the volume of intake water. The results are summerized as follows; 1. In the Control group as compared to the Normal. the amount of protein of 24 hours urine was significantly increased, the concentrations of albumin and total protein were significantly decreased. Total lipid, cholesterol and triglyceride in the serum were significantly increased. The concentrations of creatinine, BUN, uric acid in the serum, the amount of glucose and occult blood of 24 hours urine were also increased significantly. 2. In the Geumguesingitang group as compared to the Control, the increase in the amount of urinary protein during 24 hours induced by PAN was significantly suppressed, and the concentrations of total protein and albumin in the serum were significantly increased. The concentrations of total lipid, cholesterol and triglyceride in the serum were significantly inhibited. The decrease of the concentrations of creatinine and uric acid in the serum were also observed significantly. 3. In the Dohongsamultang group as compared to the Control, the increase of the amount of protein and glucose of the 24 hours urine induced by PAN were significantly inhibited, and the concentrations of total protein and albumin in the serum were increased significantly. The concentrations of total lipid, cholesterol and triglyceride in the serum were decreased significantly. The decrease of the concentrations of creatinine and uric acid in the serum were observed significantly.

We analyzed total protein (TP), albumin (AL), aspartic aminotransferase (AST), alanine aminotransferase (ALT), urea nitrogen (UN), creatinine (CRE) and serum protein electrophoretic fractions in sera of rural elderly patients to evaluate the health status in rural elderly patients. We observed that the frequencies of patients showed lower level of total protein, albumin, and both total protein and albumin than them of reference range were 20.3%, 22.8% and 19.0%, respectively. The rates of patients showed higher level of AST, ALT, both of AST and ALT, UN, creatinine and both of UN and creatinine than them of reference range were 33.8%, 40.0%, 30.0%, 17.7%, 15.2% and 7.9%, respectively. Comparison of protein fractions of each patient to reference range showed that 77.2% of patients showed normal in all of patterns. Few of patients showed abnormal pattern in albumin (13.6%), ${\alpha}1-globulin (0.0%),\;{\alpha}_2-g10bulin(1.1%),\;{\beta}-globulin(1.9%)\;and\;{\gamma}-globulin(6.2%)$. These data suggest that many of rural elderly patients may suffer from heart, liver and kidney diseases. The serum protein fractions are not typical criterion to evaluate the disease, but production of proteins in rural elderly patients may be affected by liver disease and kidney disease.

Vancomycin is a frequently used antibiotic in intensive care units, and the patient's renal clearance affects the pharmacokinetic characteristics of vancomycin. Several advantages have been reported for vancomycin continuous intravenous infusion, but studies on continuous dosing regimens based on patients' renal clearance are insufficient. The aim of this study was to develop a vancomycin serum concentration prediction model by factoring in a patient's renal clearance. Children admitted to our institution between July 1, 2021, and July 31, 2022 with records of continuous infusion of vancomycin were included in the study. Sex, age, height, weight, vancomycin dose by weight, interval from the start of vancomycin administration to the time of therapeutic drug monitoring sampling, and vancomycin serum concentrations were analyzed with the linear regression analysis of the mixed effect model. Univariable regression analysis was performed using the vancomycin serum concentration as a dependent variable. It showed that vancomycin dose (p < 0.001) and serum creatinine (p = 0.007) were factors that had the most impact on vancomycin serum concentration. Vancomycin serum concentration was affected by vancomycin dose (p < 0.001) and serum creatinine (p = 0.001) with statistical significance, and a multivariable regression model was obtained as follows: Vancomycin serum concentration (mg/l) = -1.296 + 0.281 × vancomycin dose (mg/kg) + 20.458 × serum creatinine (mg/dl) (adjusted coefficient of determination, R² = 0.66). This prediction model is expected to contribute to establishing an optimal continuous infusion regimen for vancomycin.

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.
