Abstract
During kidney and other organ transplantation, the organ to be transplanted, must inevitably remain out of the body with little or no blood perfusion at all for a long period of time (ischemia). These events have been suggested to cause the formation of oxygen- derived free radicals (OFR). Reperfusion (reintroduction of blood flow) will further exacerbate the initial damage caused by the ischemic insult and may result in the production of free radicals. The aim of this study was to investigate whether induction of brief periods of renal artery occlusion (ischemic preconditioning, IPC) can provide protection from the effects of a subsequent period of ischemia and reperfusion (IR) in the rat kidney.
Materials and Methods: In this regard, 28 white, male rats were randomly and equally divided into four groups: Control (sham- operated), IPC alone, IR alone (30 min ischemia followed by 10 min reperfusion), and IPC- IR. Preconditioning involved the sequential clamping of the right renal artery for 5 min and declamping for 5 min for a total of 3 cycles. To demonstrate the effectiveness of IPC regimen, vitamin E as an endogenous antioxidant and an index of lipid peroxidation was measured by HPLC after its extraction from right renal venous plasma and right renal tissue.
Results: Results of this study showed that the amount of vitamin E of renal tissue and venous plasma in the IR group had a significant decrease when compared to the control group (P< 0.0001). Whereas the amount of this vitamin in both renal tissue and venous plasma of the IPC- IR group was significantly higher than that in the IR group (P< 0.0001), but did not show any significant difference with the control group.
Conclusion: In this study, preconditioning method prevented the reduction of the endogenous antioxidant (Vit. E) in encountering the following sustained ischemic insult. Therefore, we suggest that ischemic preconditioning can be used to protect the Vit. E level of kidney from its subsequent decrease by ischemia and reperfusion.

Abstract
Background: Despite recent improvement in coronary intervention, there are many controversies about it’s results in diabetic patients. The goal of this study is comparison of in hospital outcome of diabetics after coronary intervention with nondiabetics.
Methods: In this study 115 diabetic and 115non diabetic patients who admitted for coronary intervention in our center during 1383&84 were entered in an analytic study of Cohort type. Datas about clinical, aniographic, procedural and post procedural (24hours) characteristics were entered in each patient’s form. Independent T test,chi-square and Fisher’s exact test were used for analyzing datas.
Results: The Diabetic Patients were most often older men, and they had higher angina class, more co-risk factors and lower ejection fractions. Diabetic’s lesions were longer and more located in proximal portion of vessels. But success rate, major complication (death, revascularization, Q Wave MI and CVA), and minor complications (coronary/peripheral arteries complication, pulmonary edema, ischemic ECG) had no significant differences between two groups.
Conclusion: Diabetes mellitus does not affect short outcomes of coronary intervention as an independent factor. So intervention could be done in these patients with considering favorable outcomes.

Abstract
Background: Creatine kinase is a cardiac biomarker that is used for the assessment of ischemic injuries and myocardial infarction. The present study was designed to evaluate effects of oxytocin administration during ischemia and reperfusion periods on CK-MB levels in the coronary effluent of isolated rat heart and the possible role of oxytocin receptor, nitric oxide (NO), prostacyclin and mitochondrial ATP-dependent potassium channels in this regard.
Methods: Male wistar rats (n=8) were anesthetized with sodium thiopental and their hearts were transferred to a Langendorff perfusion apparatus. All animals were randomly divided into nine groups as follow in the ischemia-reperfusion group, hearts underwent 30 min of regional ischemia followed by 120 min of reperfusion. In oxytocin group, hearts were perfused with oxytocin 5 min after ischemia induction for 25 min. In other groups, 35 min prior to oxytocin perfusion, atosiban (a non-specific oxytocin receptor blocker), L-NAME (an NO synthase inhibitor), indomethacin (a non-specific cyclooxygenase blocker) and 5-HD (a specific mKATP channel blocker) were perfused for 10 min. In all groups, we measured CK-MB levels in the coronary effluent at the end of reperfusion. Moreover, coronary flow (mL/min) was measured at baseline, during ischemia period and 60 and 120 min after reperfusion.
Results: Oxytocin administration significantly reduced CK-MB level in oxytocin group as compared to ischemia-reperfusion group. Administration of atosiban, L-NAME, indomethacin and 5-HD prior to oxytocin perfusion abolished the effects of oxytocin on CK-MB levels.
Conclusion: Administration of oxytocin during ischemia and reperfusion periods deceased CK-MB levels but infusion of atosiban, L-NAME, 5-HD and indomethacin inhibited oxytocin from exerting its effects.

Background: Acne vulgaris is self-limiting, multifactorial disease involving sebaceous glands. Omeprazole is a proton pump inhibitor with in vitro antibacterial effects against staphylococcus aureus and anti-androgen that can be potential treatment of acne vulgaris. This study was designed to evaluate the efficacy of oral omeprazole and erythromycin 4% compared to doxycycline combination therapy in the treatment of acne vulgaris.
Methods: In this clinical trial study, patients with moderate acne were referred to Skin Diseases and Leishmaniasis Research Center, Isfahan University of Medical Science, Iran, during August 2014 until November 2015 and were randomized into two groups receiving topical erythromycin 4% plus omeprazole (34 patients) or doxycycline (35 patients) for 3 months. Moderate acne, lack of sensitivity to proton pump inhibitors, lack of warfarin, phenytoin, diazepam consumption, lack of active liver or kidney disease, being older than 12 years, were considered as inclusion criteria. Pregnant or lactating patients, patients with drug allergy history, patients taking oral contraceptives, acne topical medications (including retinoids) or systemic treatment within 30 days of study, patients with oligomenorrhea, hirsutism, acne conglobata, acne fulminant or body acne alone were excluded from the study. All patients were tested for Helicobacter pylori test at the beginning of the study.
Results: Both inflammatory and non-inflammatory lesions decreased in both groups with negative correlation with age (P< 0.05). There was no significant correlation between positive Helicobacter pylori test and inflammatory or non-inflammatory lesion reduction (P= 0.794, P= 0.514). Also, patient satisfaction and rate of total drug side effects was not different between two treatment groups. Rate of skin reactions was 20.58% in omeprazole treated group and 11.42% in doxycycline group. For side effects, other than skin it was 2.94% versus 14.28% respectively.
Conclusion: Omeprazole could be suggested as an alternative for doxycycline in the treatment of patients with moderate acne vulgaris especially in non-inflammatory lesions.

Abstract
Background: One of the most important causes of chronic liver disease is hepatitis C virus (HCV), which causes liver cirrhosis and hepatocellular carcinoma. To control the prevalence of the disease, knowledge and information in risk factor of HCV are required. The aim of this study was to compare the risk factors of infection between HCV patients with genotypes 1a and 3a.
Methods: This is an observational analytical study. HCV patients who referred to the clinic of hepatology, Rasoul-e-Akram University Hospital from July 2015 to July 2017, were assigned to the genotype 1a and 3a. Demographic (age, sex, family history), clinical (cirrhosis, hepatocellular carcinoma) and laboratory data, history of intravenous drug and alcohol usage, and history of imprisonment were gathered and compared between two groups. All the patients completed the informed consent form. Data analysis was performed by SPSS software, version 22 (IBM SPSS, Armonk, NY, USA). P value less than 0.05 was considered statistically significant.
Results: Overall, 97 HCV patients were included in this study. Mean age was 45±12 years and 78 (80%) of patients were male. Among them, 58 (60%) and 39 (40%) had genotype 1a and 3a. respectively. History of injection drug usage was recorded in 34/39 (87%) of patients with genotype 3a, and significantly higher in genotype 3a as compared to genotype 1a [OR adj: 3.1, CI (1.3-6.2)]. Also, in this study, genotype 3a was significantly recorded in younger patients [OR adj: 1.7, CI (1.2-4.1)]. However, cirrhosis and hepatocellular carcinoma was more common in patients with genotype 1a as compared to genotype 3a [OR adj: 2.05, CI (1.6-5.4) and OR adj: 2.8, CI (1.3-5.7)] respectively.
Conclusion: According to the results of this study, hepatitis C virus transmission risk factors differed in genotypes 3a and 1a. Genotype 3a is found among young patients with a history of intravenous drug usage and genotype 1a in patients with cirrhosis and hepatocellular carcinoma.

Abstract
Background: Systemic sclerosis is an autoimmune disease affecting connective tissues, (including epidermal, subepidermal, microvasculature, etc.), leading to various extent of end-organ damage. The leading cause of mortality among these patients is lung involvement. The cardiovascular events happen more frequently in patients suffering systemic scleroderma, comparing to healthy population. This study was designed to clear the correlation between development of coronary calcification (as an indicator of atherosclerosis) and lung disease in these patients.
Methods: All patients with definite diagnosis of systemic sclerosis, who referred to Shahid Modarres Hospital between March 2011and March 2014, entered to the study. Patients suffering hypertension, hyperlipidemia and who had a past or current history of smoking were excluded from the study. Atherosclerosis was determined by coronary calcium score (based on Agatston score) and the severity and extent of lung disease was assessed by wells scoring system and Warrick scoring system (based on lung CT scan without contrast). The spearman correlation analysis was done on the data by SPSS software, version 20 (IBM SPSS, Armonk, NY, USA). All the patients had informed consent and no additive charge was delivered.
Results: The study population consisted of 25 patients with systemic sclerosis. 21 patients were female and the 4 other ones were male. The mean age was 67±4 years old. The mean Wells score in patients was 13±2.59, the mean Warrick severity score was 6.54±6.16 and the mean Warrick extent score was 14.42±14.59. No correlation was observed between presence of calcification in coronary arteries (Wells score r2=0.63 P=0.77, severity score r2=0.27, P=0.2, extent score r2=0.11, P=0.6), aorta annulus (Wells score r2=0.04, P=0.83, severity score r2=0.06, P=0.77, extent score r2=0.06, P=0.76) and thoracic aorta (Wells score r2=0.05, P=0.83, severity score r2=0.03, P=0.9, extent score r2=0.03, P=0.9) with the severity and extent of lung involvement.
Conclusion: It seems that the presence of coronary atherosclerosis or calcifications in aorta annulus and thoracic aorta (assessed by Agatston calcium score) has no significant correlation with the severity and extent of lung disease (assessed by Wells and Warrick score) in patients with systemic sclerosis. |

Abstract
Background: Trichomonas vaginalis is one of the main causes of vaginitis and cervical inflammation worldwide. Almost half of sexually transmitted and curable diseases worldwide can be assessed through the examination of this disease, so the aim of this study is to determine the prevalence of trichomoniasis in Iranian women.
Methods: This study is a review of the SID, PubMed, Science Direct, and Google Scholar databases, conducted up to September 2023. The extracted data were analyzed using CMA software (version 2). A search of articles in Science Direct, SID, PubMed, and Google Scholar databases was conducted in accordance with the PRISMA statement criteria, including systematic search, screening of articles, and selection of appropriate studies. The words used for the search and final review in this systematic review were determined based on MESH Terms in the PubMed database. These keywords that were used and selected in this study were in English and Persian. The final information obtained from the studies was reviewed and analyzed using the Comprehensive Meta-analysis (CMA, Version 2) software, and finally the heterogeneity of the studies was examined with the I2 test.
Results: Based on the search for studies and their screening, 22 studies were finally included in the meta-analysis. This study included a sample size of 49,990 Iranian women who were included in the study. In the heterogeneity analysis based on the studies obtained, the heterogeneity was 99.7. Due to the heterogeneity of the studies, the random effects method was used for the final analysis. The prevalence of Trichomonas vaginalis in Iranian women was reported to be 9.3 (95% CI: 4.6-18) based on the 22 final studies and meta-analysis. The publication bias analysis indicated the absence of bias in the studies (p: 0.175).
Conclusion: Based on the prevalence report in the meta-analysis, a relatively high prevalence was reported in Iranian women, and this situation requires more awareness raising through health centers to families, as well as care and screening of women in these centers and also in obstetric centers.
