Abstract
Abstract Background: Prostate cancer is the most common cancer in American's men and is the most common malignancy after skin in men. The purpose of this research was comparison of demographic characteristic of patients with advanced prostate cancer treated with surgical and medical orchiectomy. Materials and Methods: This retrospective cross- sectional analytic study carried out on 53 patients with locally advanced and metastatic (stages III- IV) prostate cancer referring to oncology wards in Buali hospital in Hamadanand and Vali-e-Asr hospital in Arak for adjuvant therapy of chemotherapy or radiotherapy during 2003-7. Demographic characteristics such as age, disease stage, cultural status, habitancy, socioeconomic status and patients accepted treatment of advanced prostate cancer treated with surgical and medical orchiectomy (hormone therapy), were determined and compared. Results: There was a significant difference between age mean of patients treating by orchiectomy and hormone (p=0.007). Also socioeconomic status distribution in two groups was different (p= 0.025). Distribution of disease stage, cultural level, habitancy in two groups were similar (respectively p=0.207, p=0.617, p=0.272). Conclusion: People less tend to orchiectomy to hormone therapy. Also, in high socioeconomic status and in elder, tendency to surgical orchiectomy is more.

Abstract
Background: Ischemia/reperfusion-induced acute renal failure causes excretory functional disorders of nephrones. Ischemia/reperfusion injury increases iNOS expression in the renal tissue. Inhibition of iNOS expression and its activity can ameliorate ischemia/reperfusion-induced renal injury. The aim of this study was to determine the role of iNOS on progression of renal functional disturbances over the immediate post-ischemic reperfusion period. Materials and Methods: In this experimental study, renal hemodynamic and excretory functions were evaluated in male Sprague-Dawley rats. First, a 30-min control clearance period was taken. Then following bilateral renal artery clamping for 30 minutes, four consecutive 30-min clearance periods were taken during reperfusion, while saline or L-NIL as a selective iNOS inhibitor was infused. In plasma and urine samples, Cr and sodium concentration levels were measured. Results: Renal ischemia for 30 minutes decreased glomerular filtration rate and urine osmolality during reperfusion and increased urine flow and sodium excretion. L-NIL did not change the glomerular filtration rate and urine osmolality prior to ischemia but it improved them during reperfusion and there were progressive increases in urine flow. Additionally, L-NIL lowered ischemia-induced rises in sodium excretion. Conclusion: iNOS had a considerable role in the development of disorders in hemodynamic and excretory renal functions during early hours after ischemia.

Abstract
Background: Urolithiasis is one of the causes of renal colic. The annual incidence of this disease is 1-2/1000 people. Due to the severity of pain, adverse effects of routine treatments and incomplete pain relief, more effective methods of treatment have always been sought for. Alhagi Pseudalhagi distillate is a traditional herbal medication used for urolithiasis. Due to its wide availability and no previous report of adverse effects, we decided to evaluate its impact on ureteral stone expulsion. Materials and Methods: In this single-blind randomized clinical trial, 100 renal colic patients whom visited in Arak Vali-asr Hospital or its clinics were divided into two groups. Group1 received Thiazide, Tamsulosin, and analgesics and group 2 received Alhagi Pseudalhagi distillate in addition to aforementioned drugs. The patients were followed upto 4 weeks and the stone expulsion rates and their times were compared. Results: The average stone sizes for groups 1 and 2 were 4.66 and 4.32 mm, respectively (p=0.128). Stones in both groups were mostly located in lower ureter (p=0.551). Expulsion occurred in 40% of group 1 and 66% of group 2 patients (p=0.009). The mean expulsion times for groups 1 and 2 were 11 and 9 days, respectively (p= 0.291). Conclusion: Alhagi Pseudalhagi distillate had a significant effect on the rate of stone expulsion and it is likely to decrease the time needed for the passage of Urolithiasis stones.

Abstract
Background: This investigation was designed to determine the effects of a selective A1-AR antagonist (DPCPX) on renal hemodynamic and excretory dysfunctions induced during the early hours of ischemia/reperfusion (I/R). Materials and Methods: In this experimental research, rats were anaesthetized by sodium pentobarbital, and their renal arteries were, then, occluded for 30 min, four hours after the reperfusion period. There was a clearance period during the last one hour of reperfusion period throughout which urine was collected under 30-mm of paraffin, and arterial blood samples were taken during its beginning and end. Animals were divided into four groups DPCPX (2 mg/kg) or normal saline were injected 30 min before renal ischemia to the two groups of I/R+DPCPX and I/R, respectively, and to DPCPX and Sham groups which were subjected to surgery without clamping of renal arteries, respectively. Results: I/R resulted in elevations of plasma osmolality, plasma concentrations of Na, K, creatinine, and urea, fractional excretions of Na, K, and bicarbonate, absolute bicarbonate excretion, and urinary pH, but it induced reductions in arterial bicarbonate concentration, pH and Pco2, creatinine clearance, absolute excretions of Na and urea, free-water re-absorption, and urinary osmolality in the I/R group in comparison to the Sham group. Comparison between I/R+DPCPX and I/R groups showed that applying DPCPX could improve I/R-induced alterations in most of these parameters. Conclusion: Activation of A1-AR during the early hours of reperfusion following renal ischemia definitely contributes to the development of disorders in hemodynamics, tubular Na re-absorption, as well as excretions of K, urea, and acid-base.

Abstract
Background: Noticing the fact that graft survival rate of kidney transplantation from live donors is more than deceased donors, this study was conducted to determine the relationship between the graft survival rate of renal transplantation and the donor source in patients transplanted from March 1999 to March 2009 in Namazi Hospital Transplantation Center of Shiraz. Materials and Methods: In this retrospective cohort study which was designed to determine the relationship between graft survival of kidney transplantation and the donor source (related live donor, unrelated live donor, and deceased donor) in 1356 patients who were transplanted in Shiraz Transplant Center, Namazi Hospital. Kaplan-Meier method was used to determine the survival rate, log-rank test was used to compare survival curves and Cox regression model was used for ruling out the intervening factors. Results: Five-year graft survival rates of renal transplantation from related, unrelated, and deceased donors were 92.4, 92.6 and 82.1%, respectively. Also, a significant relationship was seen between donor source and survival rate of the renal allograft (P>0.001). Conclusion: The findings of this study transplanted patients with kidneys from living donors (related or unrelated) have a higher graft survival rate compared with deceased donors.

Abstract
Background: Recent studies have shown that nicotinic-amide and niacin induce significant reductions in serum phosphorous in patients undergoing hemo-dialysis. The aim of the present study was to determine the effect of nicotinic acid on serum phosphorous level in patients undergoing long-term hemodialysis.
Materials and Methods: In an 8-week cross-over randomized double-blind clinical trial, 37 patients were assigned to nicotinic acid or placebo groups with titration from 400 to 1000 mg/ daily. A 2-week washout preceded the switch from nicotinic acid to placebo or vice versa. Statistical analysis was performed using paired- sample t test.
Results: The mean dose of nicotinic acid at the end of the period was 740±204 mg/daily. Nicotinic acid showed a significant decrease in serum phosphorus after the 8-weeks treatment however no significant changes occurred in the placebo group (P =0.01). Also, nicotinic acid resulted in an increase of HDL cholesterol levels after 8 weeks.
Conclusion: Nicotinic acid can lead to a decrease and an increase in serum phosphorous and HDL cholesterol levels, respectively. However, there is need for longer trials with larger sample sizes for determining the most effective doses of this drug.

Abstract
Background: There is growing evidence that damage to spermatozoa by reactive oxygen species (ROS) plays a key role in male infertility. This study was done to review the role of oxidative stress in male infertility. Materials and Methods: In this review article, PubMed, Scopus, and EBSCO-CINAHL databases were used for finding the relevant studies. Results: Under physiological conditions, a certain level of ROS is necessary for normal sperm function. However, an excessive level of ROS produced by leucocytes and immature sperms can cause damages to spermatozoa. Oxidative stress develops when there is an imbalance between ROS production and antioxidant defense system in male reproductive tract. High levels of ROS have been detected in the semen samples of 25-40% of infertile men. Oxidative stress can induce detrimental effects on standard seminal parameters and fertilizing capacity of spermatozoa. Conclusion: Oxidative stress can induce impaired sperm function that results in poor pregnancy rate in natural conditions and assisted reproduction.

Abstract
Background: Adequately delivered hemodialysis dose has been shown to have a distinct impact upon the morbidity and mortality of patients on chronic dialysis therapy. Online conductivity monitoring (OCM) using sodium flux as a surrogate for urea allows for repeated measurement of hemodialysis adequacy in each treatment session. Materials and Methods: In this cross-sectional study, 156 treatment sessions in patients undergoing chronic hemodialysis were assessed by measurement of the conductivity performed by Diascan in AK 96 dialysis machines. Dialysis adequacy was measured by daugirdas logarithmic estimates of single-pool Kt/V. Values of calculated Kt/V and simultaneously obtained online Kt/V were compared. Statistical analysis was performed using paired sample t-test. Results: There was a statistically significant difference between calculated Kt/V and online Kt/V in this study. The mean calculated Kt/V was 1.1±0.18 and mean online Kt/V was 0.77±0.32 (p<0.001). There was a moderate correlation between calculated Sp Kt/V and on-line Kt/V (r =0.44, p=0.012). Conclusion: Despite the underestimation of hemodialysis adequacy by online conductivity monitoring in comparison with Sp Kt/V, it is a useful tool in clinical practice.

Abstract
Background: Idiopathic nephritic syndrome (INS) is one of the chronic illnesses in children. Therefore, clinical and laboratory factors that influence the clinical course of this disease are very important. Among these factors, low birthweight due to reduction of the number of congenital nephrons and subsequent glomerular hyperfiltration has been postulated as an important factor. This study was conducted to evaluate the clinical course of INS in patients with lowbirth weight in comparison to patients with normal birth weight.
Materials and Methods: In this descriptive-analytic study, 170 children with INS were selected from hospitals in Kermanshah, Urmia, Hamedan, Qazvin, and Ahvaz and divided into two groups of low birth weight (<2500gr) and normal birth weight (>2500gr). Then, the clinical course of these patients was evaluated by reviewing their medical records.
Results: Of the 170 patients, 22 had low birth weight and 148 had normal birthweight. Statistical analysis revealed no correlation between low birth weight and INS course except for age of presentation (P=0.014).
Conclusion: According to the results of this study, there is not any correlation between body birth weight and the clinical course of INS except for age of presentation.

Abstract
Background: Pruritus is the most distressing symptom in hemodialysis patients. Its etiology has not yet been delineated thus, there are no good therapeutic options. Serotonin has been reported to be a mediator of uremic pruritus while ondansetron is a potent and selective inhibitor of 5-HT3 receptors. The aim of this study was to evaluate the effect of ondansetron on uremic pruritus in hemodialysis patients.
Materials and Methods: In this randomized double-blind clinical trial, 70 patients undergoing hemodialysis with moderate and severe itching were enrolled. They were randomly divided into two groups: one group received ondansetron 8 mg three times daily and the other group was given loratadine 10 mg two times a day for 2 weeks. Pruritus scores were recorded by the patients and the mean scores were compared before and after intervention.
Results: Changes in VAS scores after treatment with ondansetron and loratadin were both significant (p=0.001), but the difference between ondansetron and loratadin was not significant (p=0.8).
Conclusion: The results showed that ondansetron was as effective as loratadin in controlling renal itch.

Abstract
Background: Renal injury following ischemia - reperfusion (I/R) is still an unavoidable problem in many remedial and medical situations. Portulaca oleracea (PO) has been known for its anti-oxidative effects. Then, the present study aimed to investigate the effect of ethanolic extract of PO (EEPO) on the renal function and antioxidant status after induction of I/R injury in the rat kidney.
Materials and Methods: A total of 30 rats (Wistar) were divided into five groups (n = 6 each). Sham group: underwent laparotomy without I/R, EEPO group: EEPO administered 300 mg/kg then was operated like sham, I/R group: was underwent renal ischemia/reperfusion only, EEPO150+ I/R and AEPO300+ I/R groups: were administered PO 150 and 300 mg/kg then underwent I/R operation. PO extract was administered for 5 days in the relevant groups by gavage. Serum urea and creatinine (Scr), the level of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH) and total antioxidant activity (TAA) were determined. Data were analyzed by ANOVA and post hoc LSD test. P values of 0.05 or less were considered statistically significant.
Results: Induction of I/R and pretreatment with PO extract, increased the level of superoxide dismutase (SOD) in comparison with sham group (p<0.05, p<0.001). There were no significant differences in the levels of MDA, GSH and TAA among different groups. On the other hand, the Scr and serum urea of the I/R and treated groups were elevated compared to the sham group (p<0.001).
Conclusion: Ethanolic extract of PO did not strongly affect the renal antioxidant status and could not prevent the renal injury following I/R.

Abstract
Background: Hemodialysis is the most common method of treatment in patients with end-stage renal diseases (ESRD). Given the importance and the role of permeability of hemodialysis membranes in removing the materials and particles, they were divided into two categories Low and High Flux.This study aimed to compare the effects of membranes in removing electrolytes and particles in ESRD patients.
Materials and Methods: In a crossover clinical trial, blood sampling from 30 patients undergoing hemodialysis was done in two sessions of hemodialysis using a Low Flux and High Flux membrane from arterial lines before and after hemodialysis in order to assess and compare the amounts of sodium, potassium, phosphorus, urea and creatinine was taken. Data were analyzed by SPSS 16 software.
Results: The mean age of samples was 47.46±10.74 years and 70% were men and 30% were women. Urea and phosphorus uptake was significantly higher in the high flux membrane (p=0.017)(p=0.006) respectively. Other parameters did not show significant differences between the two filters (p>0.05).
Conclusion: According to the results of research and high flux membrane features, we propose a high flux filter regularly be used in hemodialysis in the absence of specific ban.

Abstract
Background and Aim: Currently, the prevalence of chronic kidney disease has increased for a variety of reasons. Renal diseases, followed by dialysis and kidney transplantation, can greatly affect the People's physical and mental health. Since most of previous studies have examined the physical and often preoperative problems of kidney transplant patients and many of them have used quantitative methods, the present study aimed to investigate the psychological challenges of renal disease patients after Kidney transplantation.
Methods & Materials: The study population consisted of kidney transplant patients referred to the Nephrology Clinic of Labafinejad Hospitalin Tehran, Iran in 2019 aged 35-50 years and 1-5 years had passed since their transplantation. A semi-structured in-depth interview was done for collecting information. A purposive sampling and continued until data saturation and until no themes were available. In the end, 15 patients were interviewed. Data analysis was performed by Colaizzi’s method.
Ethical Considerations: This study with a code of IR.IAU.SRE.1398.022 was approved by the Research Ethics Committee at Islamic Azad University, Science and Research Branch in Tehran, Iran.
Results: The primary themes were divided in to 3 main themes including: Concerns and psychologically disturbing feelings, emotional and spiritual support of the family, and uncertainty of receiving specialized, financial and welfare support.
Conclusion: Patients with kidney disease after transplantation surgery have psychological challenges in addition to physical problems that are of great importance to mental health professionals. Studying these challenges can provide a deeper understanding of their psychological problems and adaptation after surgery.

Abstract
Introduction: Years after the first successful kidney transplant, there are still many questions about the best immunosuppression regimen for these patients. Various studies have shown that long-term use of calcineurin inhibitor drugs can be associated with chronic nephrotoxicity and lead to irreversible damage to the transplanted organ. Therefore, the goal is to use immunosuppressive drugs and reduce the dose of calcineurin inhibitors as much as possible without increasing the risk of transplant rejection. This study aims to compare renal function, the rate of viral infections, and the occurrence of rejection after kidney transplantation in patients on two different treatment regimens including everolimus plus a low dose of calcineurin inhibitor against the standard protocol of calcineurin inhibitor along with mycophenolic acid in 60 kidney transplanted patients.
Methods: This clinical trial was conducted at Labbafinejad Hospital in Tehran between 2018-2019 on 60 kidney transplant patients aged 18 to 65 years and for 12 months.
Results: In terms of kidney function status based on GFR, except for the first month (P=0.02), there was no significant difference between the two groups in any of the time periods (P>0.05). Also, there was no statistically significant difference between the two study groups in terms of hospitalization length after transplantation and re-hospitalization during the study (P>0.05).
Conclusions: The results of this study showed that the everolimus regimen and low dose of calcineurin inhibitor can be used de novo in transplant patients without increasing the risk of rejection in them and at the same time it may be able to reduce the incidence of viral infections after transplantation.

Abstract
Introduction: In recent years, the use of X-rays in medicine and industry has expanded significantly. X-rays can cause oxidative stress and subsequently induce destructive effects on the kidneys. On the other hand, it has been proven that according to the theory of hormesis, resistance exercises have antioxidant effects, which may be used to reduce the harmful effects of X-rays. This study investigated the effect of resistance training on oxidative stress factors and structural changes in kidney tissue in rats exposed to X-rays
Methods: Twenty-four male rats were randomly divided into 4 groups. The irradiated groups were exposed to 4Gy X-ray. The training groups were exercised 5 times per week for 10 weeks. 24 hours after the last training session, blood samples were collected for evaluation of oxidative and antioxidant factors, and kidney tissue was isolated for stereological studies. The data was analyzed by one-way ANOVA in SPSS 20 software.
Results: In this study, whole-body X-ray irradiation caused a significant increase in kidney volume (P=0.003), cortex volume (P=0.02), glomerular volume (P=0.039), and serum Malondialdehyde (MDA) level (P=0.03). Also, performing the training protocol significantly reduced kidney volume (P=0.03), cortex volume (P=0.04), glomerular volume (P=0.033), and serum MDA level (P=0.02).
Conclusions: Based on this research, it seems that resistance training can lead to a decrease in glomerular filtration by creating adaptation and increasing antioxidant defense and changes in the hemodynamics of the kidneys, and as a result, reducing the volume and number of glomeruli, reducing the volume of the cortex and kidney, and it can improve the structure of kidney tissue in rats exposed to X-ray radiation.

Abstract
Introduction: This study aimed to investigate the effects of insulin drug therapy on the kidney structure of offspring of insulin-treated diabetic mice.
Methods: After pregnancy, female Sprague-Dawley rats were divided into control, sham, diabetics induced by streptozotocin, and diabetics receiving insulin groups. Diabetic rat offspring were sacrificed on the 10th day after natural childbirth, and the left kidneys were studied for morphometric and histological studies.
Results: The weight of children of diabetic mothers showed a significant decrease compared to children of healthy mothers (P < 0.001). The weight of the offspring of diabetic mothers receiving insulin did not show a substantial change compared to the offspring of diabetic mothers. The weight of the kidneys of the offspring of diabetic mothers showed a significant decrease compared to the control group. However, the weight of the kidneys of the offspring of diabetic mothers receiving insulin did not increase compared to those of diabetic mothers. The results of the kidney sections stained with hematoxylin-eosin and trichrome Masson showed that the offspring of diabetic mothers treated with insulin did not show a significant improvement compared to the control group.
Conclusions: Although the use of insulin is one of the momentous therapeutic ways to control blood glucose in diabetics, it cannot significantly lead to the normal health of the kidneys of the offspring of diabetic mothers under insulin treatment.
