This study was performed to investigate the effects of n-3 fatty acids on renal function in male Sprague-Dawley rats of different ages 5-, 15- and 19-months old. The rats were fed a 20%(w/w) lipid diet containing 10% fish oil, compared with control animals fed a 20% lipid diet without fish oil for 4 weeks. The results were as follows: kidney weights were significantly higher in fish oil-fed rats compared to control rats. Plasma levels of total lipid, total cholesterol, and triglyceride markedly increased, with aging and LDL-cholesterol showing a significantly lower level in fish oil-fed rats than control rats. The urinary protein and glomerular filtration rate (GFR) increased with aging. GFR was higher in fish oil-fed rats. However, urinary protein was the same in the two groups. Renal medulla thromboxane B$_2$(TXB$_2$)tended to be lower in fish oil-fed 19-month-old rats. Urinary TXB$_2$and PGE$_2$were found to be higher proteinuria. Light microscopic examination showed interstitial inflammation, tubular atrophy, interstitial fibrosis and glomerular mesangium increase. Although glomerular sclerosis increased with aging, fish oil in the diet had no effect on histological changes. In conclusion, plasma lipid, urinary protein excretion and renal histological change showed a significant increase with aging. The reduction of TXB$_2$in the medulla and increase of GFR caused by fish oil indicated n-3 fatty acid could affect renal function in line with the hypolipidemic effect.

Renal failure means irreversible damage and depression of renal function, represented by glomerular filtration rate(GFR). A renal failure patient with uremia and anemia is presented. Anemia, in this patient, appeared before uremia did. A 55 year-old male patient was treated for renal failure with Weilingtang. Improvement was observed in, not only GFR, blood urea nitrogen(BUN), and creatinine, but also in such symptoms as difficulty in urine excretion, dyspepsia and abdominal swelling. But anemia appeared during treatment, so a mixture of Dangguibuxuetang(當歸補血湯) and Xiongguitang(芎歸湯) was prescribed. After this treatment, improvement in hemoglobin, and hematocrit was observed.

Twenty-one diabetic nephropathy patients with normal serum BUN(Blood Urea Nitrogen), creatinine levels and ten chronic renal failure patients with abnormal high BUN, creatinine levels were investigated to evaluate the renal function change after long term herb medicine administration. The hospitalized patients were administrated three times a day with herb medicine, which were prescribe frequently in practical oriental medicine such as many hospital and local clinics. Blood Urea Nitrogen, creatinine and glomerular filtration rate (GFR) were measured immediately after 7days medication. Serum BUN, creatinine levels in diabetic nephropathy patients changed from 17.63±4.38㎎/㎗, 1.09±0.26㎎/㎗(mean±SD) of pre-medication levels to 14.13±3.24 1,20±0.37, 14.75±2.21 1.23±0.55, 12.34±2.89 1.18±0.42 at 7th, 14th, 21th days after herb medicine administration respectively. Also 24hr urine total protein changed from 632.25±254.43㎎/㎗ of pre-medication levels to 623.18±231.56㎎/㎗ after herb medicine administration(P>0.05). Serum BUN, creatinine levels and GFR in chronic renal failure patients changed from 67.45±13.86㎎/㎗, 6.74±2.91㎎/㎗, 13.73±4.21㎖/min pre-medication levels to 61.23±17.75 6.43±2.29 15.49±3.56, 58.84±19.36 5.83±2.51 16.38±2.85, 56.39±20.33 5.64±2.52 16.73±3.40 at 7th, 14th, 21th days after herb medicine administration respectively. Therefore, there was not clinically remarkable difference in the serum BUN, creatinine, GFR levels between pre-medication and post-medication in both Group.

While cisplatin has been widely used in the treatment of a variety of cancers, nephrotoxicity is one of the major problems which frequently limit clinical usefulness of cisplatin. This study has been conducted to investigate nephrotoxicity of cisplatin in terms of changes in glomerular filtration rate (GFR) and effective renal plasma flow (EFPF) measured by the simultaneous use of $^{99m}Tc-DTPA$ and $^{131}I-OIH$, before and after administration of cisplatin, in 12 patients with lung cancer and four patients with esophageal cancer. Cisplatin was administrated at total doses of $75\sim100mg/m^2$ with two hour hydration and diuresis method. GFR determined by the use of $^{99m}Tc-DTPA$ had a good correlation with 24-hour creatinine clearance rate (r=0.77, p<0.001). GFR and filtration fraction decreased immediately after administration of cisplatin, however, they showed a tendency to be in completely recovered four weeks after administration. ERPF was not changed immediately after and four weeks after administration of cisplatin. GFR before and immediately after administration of cisplatin were analyzed with regard to age, sex, performance status, previous adminstration of cisplatin and method of administration. None of these factors had any influence on the rate of decrease in GFR except method of administration. Administration of cisplatin as a single dose lowered GFR more compared with that as divided doses. In this study, we have also demonstrated that the simultaneous use of $^{99m}Tc-DTPA$ and $^{131}I-OIH$ was a useful tool for the measurement of GFR and ERPF respectively.

We investigated the safety and efficacy of pemetrexed monotherapy in patients with lung adenocarcinoma and various renal conditions, including chronic kidney disease. We also analyzed whether baseline renal function affected progression-free survival (PFS). We retrospectively analyzed 71 patients who received maintenance-and second-line pemetrexed monotherapy. Patients were divided into two groups according to estimated glomerular filtration rate (eGFR): fair eGFR (>60 mL/min/1.73 m²) and lower eGFR (59 mL/min/1.73 m² or less). The safety and efficacy were evaluated for each group. Median ages were 73.2 years in the lower eGFR group (n=28) and 64.5 years in the fair eGFR group (n=43). Patients with a lower eGFR achieved a median PFS of 4.7 months, while the median PFS for patients with a fair eGFR was 2.7 months. The difference between the two groups was not statistically significant (P=0.075). Both groups showed treatment-related low-grade hematological and non-hematological adverse events. Pemetrexed monotherapy is safe and effective in patients with lung adenocarcinoma with a lower eGFR.

Many previously described nuclear medicine procedures to assess glomerular filtration rate (GFR) required numerous blood samples obtained over a period of several hours to determine plasma concentrations of the injected radiopharmaceuticals. And other indirect methods of determining renal clearance have some problems due to individual variations in volume of distribution of the radionuclides used. Rescently reported Jackson's method have the great advantages that is a direct measurement method requiring less than 40 min of imaging time and single blood sampling. And it correctly accounts for individual variations in volume of distribution of the radiopharmaceuticals and can be done with routine renal scintrgraphy. We measured $^{99m}Tc-DTPA$ renal clearance with Jackson's method during the routine $^{99m}Tc-DTPA$ renal scintigraphy in 63 patients admitted to department of internal medicine in SNUH. In 23 cases among 63 patients creatinine clearence was accounted simultaneously. The range of $Cl_{DPDA}$ was from 19.9 ml/min to 170 ml/min and the correlation of $Cl_{DPDA}$ and creatinine clearance was discribed by Y=16.2570+0.7852 X($X=Cl_{DTPA}$ Y=creatinine clearance). And the correlation coefficient r was 0.88. We concluded that $^{99m}Tc-DTPA$ renal clearance measurement with Jackson's method was clinically useful to account GFR that can be done with routine $^{99m}Tc-DTPA$ renal scintigraphy simultaneously.

Background: Bone fractures are high in elderly patients with type 2 diabetes mellitus (T2DM). Hyperglycemia and chronic kidney disease may increase the risk of fracture prevalence via altered bone metabolism, but whether glycemic control and kidney function are associated with the risk of fracture prevalence remains unclear. This study evaluated the relationship between glycemic control and baseline estimated glomerular filtration rate (eGFR) and risk of fracture prevalence in older and middle-aged patients with T2DM. Methods: Patients who underwent a general medical check-up between 2009 and 2013 were selected from the Korean National Health Insurance Sharing Service records. Chi-square test and multiple logistic regression analysis were used to assess the relationship between glycemic control and eGFR and risk of fracture prevalence. Results: Cumulative fracture prevalence were higher in patients with T2DM, irrespective of whether they had tight or less stringent glycemic control (fasting blood glucose [FBG] ${\geq}110mg/dL$). After adjustment for baseline age and FBG, tight and less stringent glycemic control was significantly associated with increased adjusted risk of fracture prevalence in middle-aged patients with T2DM (OR=1.13, 95% CI, 1.05-1.21, p=0.0005 vs OR=1.13, 95% CI, 1.06-1.20, p=0.0001), but not in older patients. Baseline eGFR was not significantly related to fracture prevalence in either older or middle-aged patients. Conclusion: Less stringent glycemic control significantly increased the adjusted risk of fracture prevalence in middle-aged patients with T2DM. Further studies are needed to confirm the effect of tight glycemic control on fracture prevalence.
