Abstract
Abstract Background and objectives: Infection stones are the directly due to persistent or recurrent infection with Urease producing bacteria. they may be exacerbated by urinary obstruction or stasis. Also, some drug components like ciprofloxacin can be the cause of stone formation. We aimed at studing antibiotic resistance of bacteria isolated form kidney stones and Urinary tract infection(UtI). Material and Methods: This descriptive study, during 2008-2010,we obtained kidney stones and urine of 45 patients under gone nephrolithotomy in shahid Beheshti hospital of Babol, Iran. The stones were transferred to microbiology Lab in a strile Condition, after grinding, cultured on Blood Agar and Eosin-Methylene Blue(EMB) media. In Addilion, urin Samples were cultured on the for mentioned media. The Positive cultures were qualitatively evaluated and then, antibiogram was done by using Kirby Bauer method. Results: The resulte show that 10 kidney stone specimens and 8 urine samples were infected by bacteria, mostly by E.coli. In one stone sample and two urine samples, we can isolate more than one bacteria. The bacteria isolated in the stone and urine samples of six patients was the same. We could find two cases of staphylococcus inurine and one in stone culture. The bacteria isolated from stone are resistance to oflaxacin(80%) , which is higher than that to the other antibiotics. Conclusion: Based on the results, there is no relationship between the kind of kidney stone and type of bacteria. Further study needs to be done to prove this relation. Key words: Kidney stone, Antibiogram, E.coli, Infected stone.

Abstract
Abstract Background and objectives: cardiac surgery is often associated with acute kidney injury (AKI). Nowadays, AKI is typically diagnosed by an increase in serum creatinine, which is a delayed and unreliable biomarker. Recent studies recommended using the liver type fatty acid binding protein (L-FABP) as an early biomarker. Material and Methods: The urine samples of 18 adult patients undergoing cardiac surgery were collected in different times before (2, 4,8,24 hour) and after cardiac surgery for detection of L-FABP by Elisa. Results: The results from ELISA test show that the increasing amount of L-FABP in urine samples of 4 patients is a diagnostic indicator for AKI. The mean concentration of L-FABP has increased up to 17 times at 8 hours after cardiac surgery compared to before surgery. Conclusion: according to our findings, we speculated that the urinary L-FABP can be a reliable and rapid biomarker for diagnosis of acute kidney injury.

Abstract
Background and Objective: Microsporidia is an obligatory intracellular parasite known as an opportunistic infection in immunocompromised patients. Its laboratory diagnosis is relatively difficult and modified trichrome staining is a standard diagnostic method for detection of Microsporidia. The aim of present study was to identify intestinal Microsporidia in kidney- transplanted patients, using modified Trichrome Staining and Calcofluor White Methods.
Material and Methods: In 2012, 180 stool specimens were taken from kidney transplanted- patients given immunosuppressive drugs in Hamadan, Iran. To identify Microsporidia we use modified Trichrome Staining and Calcofluor White Methods.
Results: The mean duration of kidney transplant and immunosuppressive drug using was 5.5 Years. Only one female patient was positive for Microsporidia.
Conclusions: Owing to low frequency of this opportunistic infection among kidney transplanted patients, we can conclude that their hygienic conditions are good enough and they are not exposed with the parasites.

Abstract
Background and Objective: Urinary tract infections and bacteremia are the major problems in renal transplant patients, which are mostly due to immunesuppressive regimens, surgery, and exposure to the germs in hospital. The aim of this study was to determine the prevalence of bacterial agents in the blood and urine samples of kidney transplant candidates.
Material and Methods: In this one-year-long study, thirty-three renal transplant candidates were assessed for urine and blood cultures. One urine and blood samples from each patient before transplantation and three samples after transplantation were collected. The Samples, using standard microbiological methods, were investigated and infectious organisms identified.
Results: In 133 urine samples, Escherichia coli (20.5%), Enterobacter spp. (5.3%), Klebsiella spp. (3 %) and Staphylococcus epidermidis (1.5%) were isolated. In the blood samples, Enterobacter spp. (9.1%), Escherichia coli (6.8%), Staphylococcus epidermidis (3.8%) and Klebsiella spp. (0.8%) were isolated.
Conclusion: The results indicate that urinary tract infection was high in patients with transplanted kidney, and E. coli is the most common cause of this infection.

Abstract
ABSTRACT
Background and Objectives: Proper diagnosis of clinical conditions is a major goal of clinical and biochemical analyses. Recently, increasing efforts have been put on the use of less invasive sampling techniques with optimal sensitivity and specificity. The aim of this study was to investigate the applicability of saliva instead of blood for measuring biochemical parameters of liver and kidney function in healthy individuals.
Methods: Plasma and saliva samples were collected from 100 healthy volunteers to measure level of alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate aminotransferase (AST), total bilirubin, gamma-glutamyl transpeptidase (GGT), urea and creatinine using a fully automated chemistry analyzer (ACE Alera) with ready to use validated kits. Receiver operating characteristic (ROC) analysis was carried out using MediCal program to calculate sensitivity and specificity and area under ROC (AUC).
Results: The mean (standard deviation) salivary level of ALP, AST, ALT, GGT, total bilirubin, creatinine and urea was 20.9 (20.7) U/L, 25.8 (17.9) U/L, 10.6 (11.8) U/L, 9.6 (4.37) U/L, 0.16 (0.13) mg/dL, 0.09 (0.05) mg/dL and 35.6 (15.2) mg/dL, respectively. Saliva to blood ratios of ALP, AST, ALT, GGT, total bilirubin, creatinine and urea was 14%, 113%, 65%, 45%, 19%, 12% and 130%, respectively. The suggested normal saliva ranges of ALP, AST, ALT, GGT, total bilirubin, creatinine and urea were 7-98 (U/L), 31-104 (U/L), 6-31 (U/L), 15-24 (U/L), 0-0.13 (mg/ dL), 0.14-0.31 (mg/ dL) and 45-74 (mg/ dL), respectively. The calculated sensitivity and specificity values were 38% and 85% for ALP), 80% and 76% for AST, 75% and 45% for ALT, 60% 91% for GGT, 49% and 38% for total bilirubin, 20% and 91% for creatinine and 100% and 75% for urea. The AUC was higher than 0.7 for urea, GGT and AST, indicating good sensitivity and specificity of saliva testing for evaluation of these enzymes.
Conclusion: Based on the results, saliva could be as a noninvasive method of assessing kidney and liver function. Saliva may be a favorable alternative to plasma for measuring level of urea, GGT and AST in humans.

Abstract
Background and objectives: Gentamicin is an aminoglycoside antibiotic used in the treatment of Gram-negative bacterial infections. One of the side effects of this antibiotic is nephrotoxicity. In this study, the protective effect of Melissa officinalis L. extract on diabetes- and gentamicin-induced nephrotoxicity was studied.
Methods: Forty male Wistar rats were randomly divided into four groups. The first group received distilled water, and the second group received M. officinalis L. extract (100 mg/kg) for 28 days. The third group received streptozocin (60 mg/kg) for 18 days, and then received gentamicin (80 mg/kg) on day 20 for 8 consecutive days. The fourth group received streptozocin, gentamicin, and M. officinalis L. extract for 28 days. Serum levels of blood urea nitrogen (BUN), creatinine, glucose, and amylases were measured. The right kidney was maintained in 10% formalin for hematoxylin and eosin staining, and oxidative stress markers in the left kidney were assessed.
Results: In the third group, serum BUN, creatinine, glucose, amylase, and malondialdehyde (MDA) increased, while glutathione peroxidase, superoxide dismutase, and catalase activities decreased significantly compared to the other groups (P<0.05). The extract of M. officinalis L. significantly inhibited the enhancement of serum creatinine, BUN, glucose, amylase, and MDA (P<0.05). Histological examinations showed that diabetes and gentamicin could lead to kidney damage by inducing necrosis and inflammation. Finally, the extract of M. officinalis L. could significantly reduce the adverse effects of both gentamicin and diabetes (P<0.05).
Conclusion: The extract of M. officinalis L. improves biochemical parameters and histological lesions in diabetic rats treated with gentamicin.

Abstract
Background: Autosomal dominant polycystic kidney disease (ADPKD) is a multisystem disorder characterized by progressive renal cysts formation and extra-renal manifestations. Infection within the cysts and abscess formation are rare but life threatening if left untreated. We present a rare case of peritonitis presentation due to intraperitoneal rupture of an infected cyst in a woman with polycystic kidney disease.
Case description: A 42-year-old woman presented with constant progressing abdominal pain and vomiting. She complained of abdominal distention, bloating, and a change in bowel habits from two days ago. On physical examination, bilateral enlarged masses of flanks, generalized tenderness, and distention of the abdomen were found. The patient received conventional therapy. After appropriate fluid and electrolyte management and rescue care, appropriate antibiotics were prescribed, and laparotomy was performed. The rupture of an infected cyst of the right polycystic kidney into the peritoneal cavity was the cause of peritonitis in this patient. She successfully underwent a right radical nephrectomy (32×21cm, and 3,300 gr). The postoperative period was uneventful and the patient was discharged from the hospital after a week.
Conclusion: Antibiotic therapy is the first step in the treatment of renal cyst infection. When primary antibiotic therapy fails, drainage of the infected cyst is recommended. In medically fit patients for surgery and patients who present with complications of the infected cyst, radical surgery and nephrectomy is the procedure of choice. The best outcome is achieved after nephrectomy.

Abstract
Background: Human activities continually impact the environment negatively. Some activities are particularly linked to river pollution, and this constitutes a major problem in certain regions of Nigeria. This is a result of economic development, anthropogenic human activities, and agricultural practice that have the potential for adverse health effects. This study evaluated the effect of heavy metals acquired from the waterways on the vital organs of experimental rats.
Methods: Seventy (70) adult male Wistar rats, average weighing between 150-180g, were divided into seven groups of ten animals, each selected by simple randomization. Pooled sampled water and water containing the highest average concentration of singly and combined heavy metals noted in the waterways from three geological zones in Kwara state, Nigeria, were respectively given to the Wistar rats within the treatment groups ad libitum for 65 days. The kidney, liver, and testes were harvested and processed for paraffin embedding, and the effect of the heavy metals was histologically assessed.
Results: Histological staining revealed variable histopathological alterations in the kidney, liver, and testes of rats in the treatment groups in comparison to the control group.
Conclusion: Increased levels of heavy metals in waterways can adversely affect the organs when used for household purposes. Activities in these water bodies must be checked by regulatory agencies, and laws to discriminate against the dumping of waste in water bodies should be enforced.

Abstract
Background: Various analytes are used to assess glycemic control in laboratory medicine. Glucose measurements show current glucose levels, but sample stability can be influenced by diet and stress. Hemoglobin A1c (HbA1c) is the best marker for long-term control but can be affected by elevated urea levels. This study compared glycated albumin (GA) and HbA1c in diabetic patients undergoing hemodialysis.
Methods: A comparative cross-sectional study was conducted with a sample size of 280 volunteers. Among these, there were 115 diabetic patients with end-stage renal disease (ESRD), 95 diabetic patients without ESRD, and 75 non-diabetic patients with ESRD. Laboratory measurements included HbA1c, GA, urea, and creatinine, assessed using standard laboratory techniques. Data analysis was carried out using SPSS statistical software.
Results: Levels of HbA1c were lower in diabetic patients with ESRD compared to diabetic patients without ESRD. In contrast, GA levels were higher in diabetics with ESRD. A significant negative association was observed between HbA1c levels and urea levels. However, creatinine levels were not associated with either HbA1c or GA.
Conclusion: The estimation of glycated hemoglobin levels can be affected by high blood urea. Therefore, GA may be a better glycemic indicator for diabetic patients with ESRD.
