Non-alcoholic fatty liver is one of the most common diseases. Nutrition and exercise are recommended for the patients with this disease, and chicory is considered due to its protective effects on the liver. Therefore, the aim of the present study was to investigate the effect of chicory extract along with treadmill walking on the hepatic transaminases levels and tissue changes in rats with non-alcoholic fatty liver disease.
In this experimental study, 56 mature male rats were divided into control (without treatment), sham (treatment with high-fat diet 10 ml/kg) and 5 experimental groups receiving high-fat diet (10 ml/kg) with 200 and 100 mg/kg chicory extract alone and with treadmill walking. Chicory was administered as gavage in 28 consecutive days. At the end, after anesthetizing the animals and collecting blood from their hearts the Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT) and Alkaline phosphatase (ALP) enzymes were measured. The their livers were removed and after preparing the tissue sections, the results of hepatic enzymes measurements were analyzed by ANOVA and Duncan tests and P≤0.05 was considered significant.
The results showed that high-fat diet increased AST, ALT and ALP enzymes and hepatic tissue damage compared to the control group at p The results showed that high-fat diet increased the levels of ALT, AST and ALP, and hepatic tissue damage. Treadmill walking and chicory extract alone and together reduced the above enzymes and improved the hepatic tissue structure.

In recent years¡ Computed Tomography (CT scan) has become the Gold Standard for detecting urinary stones. This study was conducted to predict the size of possible passage of ureteral stones based on clinical signs, lab data (e.g. Ultrasounds) in patients with small passable stones and to prevent CT scan, which requires high costs and x-ray exposure.
In this cross- sectional study, fifty consecutive patients from emergency room who had clinical symptoms of renal colic and urinary tract stones were recruited by simple non-random sampling. After obtaining the primary data, all of them underwent sonography (US), and in those without sings of stone in US¡ CT scan was performed. Based on the CT scan, the patients were divided into two main groups: 1) patients who had no ureteral stones or had ureteral stones Among our proposed variables, previous history of urinary stone (p=0.05), irritative urinary symptoms (e.g. dysuria, frequency and urgency) (p=0.001), gross hematuria (p=0.049) and degree of hydronephrosis (p=0.029) had statistically significant relationship with the presence, size and spontaneous expulsive potential of ureteral stones.
Based on our results, negative history of urinary stones, absence of irritative urinary symptoms and gross hematuria and absence or mild degree of hydronephrosis in sonography were in favor of small (

Artemisia absinthium (known as wormwood) is used as an antihelminthical, antimalarial, antiseptic and anti-inflammatory agent, and is used for treatment of gastric pain in the traditional medicine. In the present study, we evaluated the effects of hydroalcoholic extract of A. absinthium on the ovary tissues and pituitary_gonadal axis of the adult female NMRI mice.
In this experimental study, intraperitoneally (IP) injections of hydroalcoholic extract of A. absinthium, were performed over 30 days on 50 mice with 50 (first group), 100 (second group), and 150 mg/kg.bw (third group) doses. The sham group was received distilled water and control group received no injection. After 30 days of injections, the animals were dissected, and blood samples were collected by heart aspiration. The levels of LH, FSH, estrogen and progesterone of serum were measured by ELISA method. Seven µm sections of ovary were prepared by a microtome and stained by H&E method. Data were analyzed by One-Way ANOVA and Tukey post- hoc test. The Significance level was set at p Our findings indicated a significant reduction (p Therefore, it can be concluded that Artemisia absinthium hydroalcohlic extract in high doses has damaging effects on the process of oogenesis, which may be due to α and β Thujoun, Alkaloid and Saponin constituents in this plant.

the interaction of albumin- the most important plasma protein- with various drugs leads to variations in the pharmacokinetics of drugs. Since interaction of different pharmaceuticals with albumin is determinant in the estimation of dose and prediction of drug-drug and drug-food interferences, studying the binding ability of different drugs with albumin is an active area of research.
Docking studies were performed by Lamarckian Genetic Algorithm of AutoDock 4.2 program. The three-dimensional structures of albumin were obtained from Brookhaven protein data bank (2BXD & 2BXF; www.rcsb.org). Pre-processing of molecules was done using AM1 method and AutoDock Tools 1.5.4 software. AM1 optimization method was performed using Polak-Ribiere (conjugate gradient) algorithm with termination condition as RMS gradient of 0.1 Kcal/Å mol. Schematic representation of drug-albumin complexes were obtained by Ligplot.
Oxiconazole and fenticonazole were top-ranked drugs in binding to site 1 (subdomain IIA) and 2 (subdomain IIIA) of albumin, respectively (∆Gb -9.01 and -9.89 kcal.mol-1). Leu238 and Ala291 were the key residues of site 1 due to hydrophobic contacts with all of the antifungals, while Ile388, Asn391 and Leu430 were the key residues of site 2. A few structure binding relationship rules could be extracted from the binding pattern of antifungal drugs.
It was found that antifungal agents might have higher affinity toward site 2 of albumin rather than site 1. Estimated high albumin affinities of antifungals provided the possibility of drug-drug or drug-food interactions. It seemed that hydrophobic contacts were more significant in binding antifungals to albumin.

Colorectal cancer is one of the most common cancers in the world. Much attention has been given to nutritional supplements that can alter intestinal flora as factors preventing colon cancer. Research has shown that lactic acid bacteria in foods are potentially capable of inducing apoptosis. In this regard, the most focus has been on Lactobacillus genus. This study, investigated the cytotoxic effect of metabolites of isolated strain from Azerbaijan traditional cheeses on HCT116 colorectal cancer cells.
In this cross-sectional study, after collecting samples of traditional "Lighvan" and "jug" cheeses in the region of Azerbaijan, MRS medium was used for isolation of lactobacilli. The isolates were identified by biochemical and molecular approaches after primary confirmation. The metabolites were produced in MRS broth, and their supernatants were separated. The inhibitory effect of the supernatants of the isolates on HCT116 cancer cells was studied and their effects were evaluated by microscopy and MTT assay.
In this study, three isolates of "Lighvan" and sixteen isolates of "jug" cheeses were obtained. The results of anticancer activity showed that the supernatants of the isolates CT2 and JT1 had a significant anticancer effect on HCT116 cancer cells (p˂0.05). Identification of the isolates CT2 and JT1 showed 99% and 96% similarity with Lactobacillus brevis, respectively.
Lactobacilli in Azerbaijan traditional dairy products have a significant value in terms of anticancer properties.

Several studies have shown that pentoxifylline is an antioxidant and anti-inflammatory agent. Pentoxifylline (PTX), has been shown to exert protective effects on autoimmune disorders. The objective of the present study was to examine the effect of pentoxifylline on histopathology of pancreas in diabetic mice.
Diabetes was induced by multiple injection of low-dose streptozotocin (40 mg/kg/day for 5 consecutive days) in male C57BL/6 mice. After induction of diabetes, mice were treated with pentoxifylline (100 mg/kg/day i.p.) for 21 days. The nitric oxide levels were evaluated in spleen cell culture supernatant. Pancreases were isolated and stained by hematoxylin & eosin (H&E) and Gomori aldehyde fuchsin (GAF).
Pentoxifylline treatment significantly inhibited the production of nitric oxide (p These findings indicated that pentoxifylline might have a therapeutic effect against the autoimmune destruction of the pancreatic beta-cells during the development of STZ-induced type 1 diabetes in mice.

Azathioprine is widely used for the treatment of autoimmune diseases. It has negative effects on the function of kidney. Therefore, considering the protective effects of ginger on nephrotoxins, the present study was conducted to investigate the effect of ginger on renal changes induced by azathioprine in rats.
In this experimental study, 56 female rats were divided into 7 groups including control, sham and 5 experimental groups receiving azathioprine (50mg/kg), ginger (200mg/kg), azathioprine plus ginger (200,100 and 50 mg/kg). In this study, ginger was administered by gavage and azathioprine intraperitoneally in 21 consecutive days. At the end, serum levels of urea, uric acid and creatinine were measured and the histological structure of the kidneys was examined. The results were analyzed by ANOVA and Duncan tests at significance level of p≤0.05.
The results showed that azathioprine caused the destruction of structure along with cell necrosis, tubular degeneration, glomerular atrophy, urinary space enlargement, hyperemia and inflammatory cell infiltration in the renal tissue, as well as an increase in the serum level of urea, uric acid and creatinine at p≤0.05. However, simultaneous use of ginger and azathioprine reduced the serum levels of urea, uric acid, creatinine and improved the kidney structure compared to the azathioprine group.
The results showed that ginger had a protective effect on kidney tissue, due to its antioxidant properties, by inhibiting free radicals produced by azathioprine and decreasing the severity degradation effects of azathioprine on kidney tissue and function.

Trauma is one of the most common causes of death in the age range 1 to 44 and the third cause of death regardless of age. Abdominal trauma is one of the most common types of trauma. This study aimed to investigate the frequency of causes of laparotomy in penetrating and blunt abdominal traumas in 2016.
This descriptive study was conducted on 120 medical records of patients hospitalized for penetrating and blunt abdominal traumas in Fatemi Hospital, Ardabil, 2016. The inclusion criterion consisted of all patients undergoing laparotomy due to abdominal trauma. In this study, age, gender, education level, type of trauma (blunt or penetrating), results of laparotomy surgery, physical examination and paraclinical findings of patients before operation were collected by a researcher- made checklist.
The results showed that 80% of the patients were male and 35% were in the age range 20-29years. Of patients, 38.3% had penetrating trauma and 61.7% blunt trauma. The most common mechanism of blunt abdominal trauma was car accident (83.8%). Penetrating object was the cause of all penetrating abdominal traumas. Peritoneal stimulation symptoms were observed in 56.5% of penetrating abdominal traumas and 62.2% of blunt abdominal traumas. Hypotension was observed in 21.7% of patients with penetrating abdominal trauma compared with 62.2% in patients with blunt abdominal trauma. The most prevalent damaged organ in patients with blunt trauma was spleen (51.4%). The most prevalent damaged intraabdominal organ was small bowel (17.4%). Negative laparotomy was significantly higher in patients with penetrating trauma than those with blunt trauma (p The results of this study showed that: 1. Road traffic accident and penetrating object were the most common causes of laparotomy in patients with blunt and penetrating trauma respectively; 2. Spleen and small bowel were the most prevalent damaged organs in blunt and penetrating abdominal trauma respectively and; 3. Young males were at highest risk of abdominal traumas.

Considering the importance of prevalence studies in disease management, this study was conducted to determine the prevalence of psychiatric disorders in children and adolescents in Ardabil province. In this study, 1035 children and adolescents aged 6 to 18 were selected using cluster random sampling and examined with a digital version of the K-SADS in terms of psychiatric disorders. In the present work, 24 types of psychiatric disorders in children and adolescents were evaluated. Sampling was done in the general population and interviews were conducted at the door of the house. Assessments were carried out by experienced psychologists. The point and interval prevalence (with 95% confidence interval) were calculated for disorders. Data were analyzed using SPSS ( v.22) software. Hyperactivity, oppositional defiant, enuresis, and separation anxiety disorders had the highest prevalence in the studied sample. In contrast, psychosis, autism and panic disorders had the lowest prevalence. Depression had a moderate prevalence (1.7%) among other disorders. The overall prevalence of disturbances was 31.7%. The prevalence of psychiatric disorders in Ardabil children and adolescents was high. According to this rate, etiologic studies are necessarily needed for disorders with have high prevalence and health systems should design and manage preventive plans for the general public.

Ultrasonography as a non-invasive, inexpensive and generally available method has been used to measure of the intima-media thickness (IMT) of carotid arteries changes and finding its relationship with cardiovascular risk factors and vascular diseases. The aim of this study was to investigate the carotid arterial wall thickness (IMT) changes based on clinical and para-clinical indexes in patients with type 2 diabetes mellitus (DM). In this descriptive-analytical study, 100 patients with type 2 DM were randomly selected from all patients admitted to diabetes clinics and were considered in terms of clinical and paraclinical indexes of systemic atherosclerosis. Both types of IMT (TA and TB) were measured by ultrasonography in six locations of the carotid system. The intensity of these two values was calculated compared with the normal IMT and also, its relationship with clinical and para clinical indexes were determined. The results were statistically analyzed using SPSS software version 19. In this study, more than 80% of patients had IMT upper than normal. There was a significant difference between the severe increase of IMT and effective variables such as sex, smoking, physical inactivity, dyslipidemia and poor blood glucose control. This study showed that the DM and factors such as sex, smoking, physical inactivity had a significant effect on the increasing IMT compared to the normal range.

In recent years, the hypothesis of using anti-androgens has been increasingly addressed in the treatment of acne in women. One of these drugs is flutamide, which there is no strong evidence of its efficacy in treatment of acne in women. The aim of this study was to compare the effect of combination therapy of flutamide-cyproterone compound with flutamide-doxycycline in severe type of acne in women. In an interventional study, patients were divided in to two groups. One group (n=30) received flutamide - cyproterone compound and another group (n=30) received flutamide-doxycycline which were followed for six months. Both groups also received 1% topical clindamycin twice a day. Counting the number of lesions, changes in severity index and grading of acne were used to evaluate the patients. Patient satisfaction was also evaluated. The mean age in the flutamide-doxycycline group was 19.4±4.67 and in the flutamide-cyproterone compound group was 19.06±11.3. This difference was not statistically significant. The mean of the acne severity index at the onset of intervention between the two groups was not significant (p= 0.7). The mean of the acne severity index at the start of treatment in the flutamide-doxycycline group was 306.07±155.46 and at the end of treatment reached to 19.18±19.5, and also in the flutamide-cyproterone compound group, decreased from 293.21±15.21 to 10.5±21.8 at the end of treatment. This difference was not statistically significant (p=0.1). Both therapeutic regimen were effective in the treatment of severe type of acne and can possibly be used as an alternative treatment for severe acne.
