The purpose of this study was to explore the effects of hand reflexology on the physiological.emotional responses and immunity of the patients with chronic illness. This study looked specifically at patients with chronic renal failure(CRF) and cancer patients. Method: This study was designed as a quasi-experimental nonequivalent control group pre and post test. Subjects were 54 patients who received dialysis and chemotherapy in one hospital. Thirty-one patients were assigned to the experimental group and 23 to the control group. The hand reflexology was applied to both hands of the experiment group for ten minutes each time, 5 times during three days. For data collection, physiological lab levels, immune cells of blood and questionnaires for emotional responses were measured before and after the program. Result: BT of the experiment group was decreased significantly on both of the 1st and the 5th application. PR & BP were decreased significantly on the 1st times, but not 5th times. Hb levels of the experimental group were significantly increased. And emotional responses, vigor and mood scores of the experiment group were significantly increased. B cell & CD19 were increased significantly on the experiment group. Suppressor T cell and NK cell showed significant decrease after the program, but no significant differences between the groups. Conclusion: We have found that the hand reflexology helps the chronic patients to improve physiological.emotional responses and the immune reaction. Through this result, the hand reflexology is effective as a intervention of psychoneuroimmunologic function.

Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent hereditary renal disease and causes terminal chronic renal failure. ADPKD is characterized by bilateral multiple renal cysts, which are produced by mutations of the PKD1 and PKD2 genes. PKD1 is located on chromosome 16 and encodes a protein that is involved in cell cycle regulation and intracellular calcium transport in epithelial cells and is responsible for 85% of ADPKD cases. Although nine cases of unilateral ADPKD with contralateral kidney agenesis have been reported, there have been no reports of early childhood ADPKD. Here, we report the only case of unilateral ADPKD with contralateral kidney dysplasia in the world in a four year-old girl who was intrauterinely diagnosed since she was 20 weeks old and followed for four years until present.

Because the number of patients who require maintenance hemodialysis is increasing in number recently, angioaccess has become important to many vascular surgeons participating in the management of such patients.The authors created 269 arteriovenous fistulas[AVF] for angioaccess in 229 patients with chronic renal failure[CRF] at the Department of Thoracic and Cardiovascular Surgery in Chungnam National University Hospital during the period from August 1990 to March 1993. We analyzed the results of 260 operations for 220 patients except 9 patients who were lost during the follow up period. We performed snuffbox AVF in 171 cases, classic radiocephalic AVF in 46 cases, direct AVF at other site in 5 cases, forearm Gore-Tex AVF in 29 cases, and upper arm Gore-Tex AVF in 9 cases. We experienced 13 cases of operative failures, 11 cases of early complications, and 60 cases of late complications including obstructions during follow-up period. The 1 year, 2 year and 3 year patency rates of snuffbox AVF[Group 1], classic radiocephalic AVF[Group 2], and Gore-Tex AVF[Group 3] are like followings; 89, 84, 76% in group 1, 84, 75, 68% in group 2, and 79, 66, 55% in group 3. It showed a statistically significant difference between group 1, 2 and group 3.

Renal failure syndrome in wild mammals is infrequently reported. Muskrat (Ondatra zibethicus) is a medium-sized rodent known to carry many diseases but rarely exhibiting renal failure. A six-month old female muskrat was submitted to our laboratory for pathological diagnosis, and necropsy revealed severe renal damage with sand-like lithiasis in the ureter, renal calculi, and hydronephrosis. All major organs, including the cerebrum, also showed systemic hemorrhage and calcification which may have been due to uremia induced by renal failure. Histopathologically, necrosis and microcalcification were detected in the renal cortex and the medulla, especially in the proximal convoluted tubules and collecting ducts of the kidney. Significant hyalinization of the glomeruli was also observed, and this suggested chronic nephritis. These findings would support mycotoxic effects, particularly on the kidney. Moreover, infiltration of neutrophils and mononuclear cells was observed in the lung and of plasma cells in the spleen. The definitive cause of the toxic effects in this case of muskrat renal failure could be attributed to contaminated food.

Purpose : We analyzed the demogaphic data md clinical course of Korean children with chronic renal failure (CRF) observed between 1990 and 1999. Patients and Methods : Questionnaires were mailed to all children's hospitals ail through the country. We asked for primary renal disease age and serum creatinine levels at first presentation with CRF and end-stage renal disease (ESRD), and modes of renal replacement therapy (RRT). Results : 401 children (254 boys, 147 girls) with CRF, defined as a permanent increase of serum creatinine above 1.2 mg/dl for at least 3 months or until death, were identified. This represents an incidence of 3.68 per million child population per year. Of these patients, 22$\%$ on younger than 5 years, 28$\%$ 5 to 10 years and 50$\%$ 10 to 15 year. Eight five $\%$ of the patients could be classified with a primary renal disease. The most frequent cause is glomerulonephritis (36$\%$), followed by chronic pyelonephritis (21$\%$), renal hrpo/dylplasia (9$\%$), and hereditary nephropathies (7$\%$). Reflux nephropathy (16$\%$) was the most common single cause of CRF. ESRD was reached in 70$\%$ of all patient. 99.3$\%$ of these started RRT. Hemodialysis (HD, 42$\%$), peritoneal dialysis (PD, 35$\%$) and transplantation (TP, 23$\%$) were performed as the initial mode of RRT. A total of 161 TPs were performed (159 first grafts, 2 second grafts). A total of 32 patients died. The main causes of death were dialysis related complication in HD patients and infections in PD patients. Survival rate on any form of RRT was 88.7$\%$ during the mean follow-up period of 37 months. Conclusion Major efforts should be directed toward earlier diagnosis and treatment of reflux nephropathy to prevent occurrence of Of. Dialysis and TP have now become well accepted forms of treatment in Korean children with ESRD.

Purpose: The authors performed this study to investigate the risk factors for predicting stent failure and to evaluate its impact on prognosis. Materials and Methods: Between January 2002 and March 2017, we retrospectively reviewed 117 consecutive patients who underwent retrograde ureteral stenting and exchanging at least once every 3 months for malignant ureteral obstruction. The patients were classified according to their pre-stenting chronic kidney disease (CKD) stage. The factors affecting stent failure were analyzed using a logistic regression model. Overall survival (OS) was estimated, and the prognostic significance of each variable was estimated using Cox proportional-hazards regression modeling. Results: Before stenting, 91 patients were CKD stages 1-3 and 26 patients were CKD stages 4-5. These two groups differed significantly only in pre-stenting estimated glomerular filtration rate (eGFR), bilateral obstruction, and pre-stenting pyuria. Among the 117 patients, stent failure occurred in 30 patients (25.6%), and there were no differences between the groups. Pre-stenting pyuria and post-stenting complications were significant predictors of stent failure. There were 79 deaths in total, including 56 in the CKD stages 1-3 group and 23 in the CKD stages 4-5 group. In the multivariate analysis predicting patient OS, pre-stenting eGFR and post-stenting disease progression were significant factors. Conclusions: Internal ureteral stenting was effective for maintaining renal function in malignant ureteral obstruction. However, it did not restore renal function, which is related to the prognosis of the patients. Therefore, to improve patients' renal function and prognosis, patients who require stenting must be quickly recognized and treated.

Since renal failure causes decrease in tumor marker excretion, use of these markers in cancer care and treatment in patients with renal insufficiency or hemodialysis is controversial. The aim of this study was to investigate differences of serum levels of tumor markers CA15-3, AFP, CA19-9 and CEA in patients with impaired renal function. A total of 100 patients referred to the Tabriz Immam Reza and Amiralmomenin hospital from June 2010 to November 2011 were selected for study. Subjects were divided to 3 groups of healthy, dialysis and renal failure but non hemodialysis cases, the last category being re-grouped based on creatinine clearance. No significant relationship between different groups in serum levels of CEA (P=0.99) and CA19-9 (P=0.29) tumor markers was found. A significant correlation was observed between serum levels of AFP (P<0.001) and CA15-3 (P<0.001) and also a tendency between creatinine clearance and CEA (r=0.05, P=0.625). Creatinine clearance significantly correlated with AFP (P<0.001, r=0.53) and CA15-3 (p=0.00, r=-0.412), but not CA19-9 (P=0.089, r=-0.171). According to results of this study it appears that use of tumor markers in patients with impaired renal function should be performed with special precautions.

Purpose: Hypertension accelerates the progression of chronic renal disease, whether it results from, or causes, the renal disease. Therefore, the control of hypertension is one of the important factors that retard the rate of renal deterioration. We compared the effects of different antihypertensive agents on renal function and glomerular morphology In subtotal nephrectomized rats. Materials and methods: After induction of chronic renal failure with 5/6 nephrectomy, the rats were divided into three groups; control group (Group C), enalapril group (Group E), and nicardipine group (Group N). Systolic blood pressure was measured by tail cuff method every 4 weeks until 12 weeks after nephrectomy. At 12 weeks after nephrectomy, all rats were placed in metabolic cages for 24 hour urine collections to measure urinary protein and creatinine excretion. After urine collection and blood sampling for serum creatinine, all rats were sacrificed. The renal tissue was processed for morphometric study with light microscope and electron microscope. Results: 1. The blood pressure of Group C increased progressively, but both enalapril and nicardipine prevented the development of hypertension, and the two drugs were equally effective in maintaining normal blood pressure throughout the study. 2. Twenty-four hour urinary protein excretion was lower in Group E compared to Group C and Group N 3. Mesangial expansion score in both treated groups were significantly lower than the control group. Mean glomerular volume in Group E was significantly reduced compared to Group C and Group N. There was no significant difference in mean glomerular volume between Group C and Group N. 4. There was no significant difference in podocyte structural changes, estimated by filtration slit length density, among control, enalapril and nicardipine treated groups. Conclusion: Control of hypertension with enalapril or nicardipine afforded considerable protection from mesangial expansion in the rat remnant kidney model. But protein excretion and glomerular growth were significantly reduced in Group E compared to Group N. There was no significant difference in podocyte structural changes among the 3 groups.

Kidney diseases including acute kidney injury and chronic kidney disease are among the largest health issues worldwide. Dialysis and kidney transplantation can replace a significant portion of renal function, however these treatments still have limitations. To overcome these shortcomings, a variety of innovative efforts have been introduced, including cell-based therapies. During the past decades, advances have been made in the stem cell and developmental biology, and tissue engineering. As part of such efforts, studies on renal cell therapy and artificial kidney developments have been conducted, and multiple therapeutic interventions have shown promise in the pre-clinical and clinical settings. More recently, therapeutic cell-secreting secretomes have emerged as a potential alternative to cell-based approaches. This approach involves the use of renotropic factors, such as growth factors and cytokines, that are produced by cells and these factors have shown effectiveness in facilitating kidney function recovery. This review focuses on the renotropic functions of bioactive compounds that provide protective and regenerative effects for kidney tissue repair, based on the available data in the literature.

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.
