Abstract

Background: Gentamicin (GM) is one the aminoglycoside antibiotics which isroutinelyused to treatinfections gram-negative, either alone or insynergistic withbeta-lactamantibioticsused. However, frequent useleads toserious side effectssuch asrenal toxicity, ototoxicity. Coenzyme Q10 has antioxidant, anti-inflammatory and vasodilatory properties. According to these properties of Coenzyme Q10 and tissue damage mechanism in GM induced-nephrotoxicity, in this study, the effects of these two substances for the co-treatment and post -treatment on renal injury induced by gentamicin were investigated.

Materials and Methods:  Experiments has been done on 77 male Wistar rats in weight range of 200 to 250 g. Animals were divided randomly into 5 groups of 7 numbers. Renal nephrotoxicity induced by i.p injection of gentamicin (100mg/kg) Therapeutic effect of coenzyme Q10 (10mg/kg)in the two protocols co-treatment  and post-treatmentwas investigated.The animals after the last injectionon the ninth day of co-treatment andthe seventeenth day of post-treatmentwere placed into individual metabolic cages so as to collection urine and urine volume was measured gravimetrically. Afteranesthesia, systolic blood pressure and renal blood flow was measured. Then blood sampling was done. Amount of urea, creatinin, sodium, potassium and osmolarity was measured in plasma and urine samples. Left kidney, for doing histological experiments in 10% buffered formaldehyde and right kidney for biochemical experiments in fluid nitrogen was preserved.

Results: Co-treatment with Coenzyme Q10 significantly decreased fractional excretion of sodium (6.37±1.33 %; p<0.001) and decreased fractional excretion of potassium(219.14±83.8 %; p<0.001) MDA levels (2.13 ±0.24µmol/gkw; p<0.001), and significantly increased renal blood flow (6.38 ±0.1ml/min: p<0.01) and FRAP levels (24.44±0.42mmol/gkw; p<0.001). Post-treatment with coenzyme Q10 significantly decreased fractional excretion of sodium (3.58 ±0.57 %; p<0.001), potassium (111.77±29.4%; p<0.001) and MDA levels (3.08 ±0.12µmol/gkw; p<0.001) and significantly increased renal blood flow (6.74±0.15ml/min: p<0.001) and FRAP levels (24.34±0.75mmol/gkw; p<0.001) that is reduced by gentamicin.

Conclusion: According to the results, this study showed thatpost- treatment with coenzyme Q10more protective effect on the kidney tissue andAnda greater increase inantioxidant defensecreated.

Abstract
Abstract
Background: Systemic lupus erythematosus is a systemic disease that can lead to lupus nephritis, as one of the most dangerous sign of this disease. In this report, a woman with acute renal failure subsequent from lupus nephritis is introduced.
Case report: 27-year-old woman with no history of systemic disease caused by swelling around the eyes of one month, nausea without vomiting, anorexia, dizziness and a 2-month history of hypertension was admitted. ESR in high range, hypertension and dizziness were also observed. Important findings in the laboratory exam were including pre-orbital edema, azotemia, anemia, hematuria, proteinuria, nephropathy normal size, high titers of anti-nuclear antibody, anti-DNA antibodies and lupus anticoagulant was in a field. Renal biopsy was done and the kidney biopsy response was pauci-immune glomerolu, and the patient was treated by pulse corton and hemodialysis.
Conclusion: Lupus nephritis as an important complication of systemic lupus erythematosus should be considered, so in patients with acute renal failure, lupus nephritis should be considered, while it isn’t usually observed pausi-immune nephritisin renal biopsy in patient with lupus.

Volume 22, Issue 6 (1-2020)
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.

Volume 25, Issue 6 (3-2023)
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.
