Abstract
Introduction: Chronic diarrhea is accomp-anied with abdominal symptoms and restr-icts the activity of patient. Precise evaluat-ion of the history of patient, physical exam-ination, laboratory and radiological evalu-ation, colonoscopy and biopsy may be help-ful to determine the underlying causes of chronic diarrhea.
Materials & Methods: For the study, 100 patients (50 male and 50 female) with chro-nic diarrhea were studied. These patients had referred to Tabriz Sina hospital, Iran during 2006 to 2011. The patients were examined for the presence of fecal leuko-cytes, parasitic eggs and trophozoites. Stu-dding parameters such as colonoscopic fin-dings and final diagnoses based on intes-tinal mucous biopsy were study. Data were analyzed by using of SPSS software and the statistical tests, frequency and chi-square.
Findings: Mean age of men was 36.44 year and men age of women was 38.56 year. Colonoscopic findings were as 61% infla-mmation, 10% erosion and 29% normal. Biopsy study findings were as 59% nonsp-ecific colitis, 15% ulcerative colitis and 26% amebic colitis.
Discussion & Conclusion: Chronic diarrhea may be only one symptom of underlying di-gestive diseases. Therefore, after exclusion of infective and parasitological causes, inv-asive diagnostic method is indicated. The two method are together considered useful diagnostic tool for the management of the chronic disease and prevent the undesired economical and health problems for the patients.

Abstract
Introduction: Energy saving is an important item considering environme-nttal protection, economy and science and technology. Hence, one way of energy saving is using compact fluorescent lamps. In these lamps, ultraviolet radiat-ion is generated due to the nature of produce light. Until now, no study has investigated the proper distance to these lamps in Iran. Therefore, the present study aimed to evaluate the safe distance in facing UV rays of compact fluorescent lamps.
Materials & Methods: This experimental study was conducted on 16 compact fluo-rescent lamps (four different brands) in 8 different watts. Measurement was done in 200,150,100,50,25 and 10cm distance and 0,100,200,500,750,1000,1500 and 2000 hours from work time and in zero angles ultraviolet radiation was measured in three fields including UVA, UVB and UVC. The information was analyzed usi-ng SPSS 20 software through one-way ANOVA test.
Findings: ANOVA test showed that there was a statistically significant relationship between the intensity of ultraviolet radi-ation at different distances (P<0.05). Also, ANOVA test was done to compare theint-ensity of ultraviolet radiation at different time and results showed that there was not a significant difference between different times in terms of intensity of ultraviolet radiation(P>0.05).
Discussion & Conclusion: In 10cm dis-tance, the intensity of UVA radiation in two lamps (45 and 60 watts) was more than the occupational exposure limits bet-ween eight lamps and in 25cm and more distances, intensity of UVA radiation rea-ched less than the occupational exposure limits. Intensity of UVB radiation among most lamps in 10, 25 and 50 cm distances was more than the occupational exposure limits.

Abstract
Introduction: Metabolic syndrome has a high prevalence and and it is accompanied by a collection of clinical symtom, such as obesity, hypertension, increased fasting blood sugar and triglyceride (TG), and HDL reduction, along with increased risk of cardiovascular disease and diabetes. Recent studies have considered the reduction of antioxidant capacity as one of the important causes of the complications of this syndrome. Regarding the strong antioxidant effects of eugenol, the aim of this study was to evaluate the protective effects of eugenol on dyslipidemia induced by metabolic syndrome and serum antioxidant status in male rats.
Materials & Methods: This study was conducted on 24 rats which were randomly assigned into groups 1- Tap water recipient, 2- Water-rich fructose with 20% tween, 3-Fructose 10% and 4- Fructose 10% with eugenol mg / Kg 20 ip for eight weeks. At the end of experiment, blood samples were taken to measure the levels of cholesterol, triglycerides, LDL, HDL, malondialdehyde (MDA) and total antioxidant capacity of plasma (TAC). Data are expressed as mean ± SEM. The levels cholesterol, triglycerides, LDL, HDL, MDA andTAC were analyzed by one-way analysis of variance (ANOVA) followed by the Tukey test.
Findings: It was revealed that adding fructose to drinking water led to significant increase in animal weight, serum cholesterol and triglyceride levels, LDL and SGOT, and serum HDL levels (P <0.05). Eugenol decreased serum levels of cholesterol, triglyceride, LDL, MDA and increased serum SGOT, TAC and HDL levels (P <0.05). Serum SGPT levels did not show significant differences among the groups.
Discussion & Conclusions: Eugenol improves metabolic syndrome markers and also increases the antioxidant activity of the plasma.

Abstract
Introduction: Today, the use of magnetic nanomaterials promises purposeful and intelligent drug delivery. These magnetic drug nanocarriers can respond appropriately and intelligently to the external magnetic field, which can be used to selectively release the drug into the target tissue. Therefore, this study investigated the synthesis of zinc ferrite nanoparticles and some of their structural, electronic, and magnetic properties. The ultimate goal of this study is to use nanotechnology and quantum mechanics in intelligent and targeted drug delivery to improve the patient's quality of life and reduce the destructive effects of unwanted drug distribution in healthy tissues.
Material & Methods: In this study, zinc ferrite nanoparticles were prepared using heat treatment, and then the structural and magnetic properties of these nanoparticles were investigated using imaging-measurement methods on the nanoscale. In addition, cytotoxicity test (MTT) was performed on mouse fibroblast cell line (NIH3T3), and the results were analyzed using SPSS software. Moreover, using the results of quantum calculations, the chitosan molecular system was proposed as a coating for this drug carrier.
Findings: Analysis of the results obtained from X-ray diffraction (XRD) and electron microscopy (SEM) spectra confirmed the existence of spinel structure and the small size of these particles (20-23 nm). Furthermore, the results obtained from the vibrating magnetometer and the paramagnetic resonance spectrometer showed the presence of paramagnetic properties in the synthetic nanoparticles. In addition, the analysis of the results obtained from the vibrating magnetometer shows the low magnetic residue of the synthetic magnetic nanoparticles. This can be useful in the mechanism of targeted drug release. In addition, analysis of cytotoxicity (MTT) test results on synthetic nanoparticles showed that the toxicity of these nanoparticles depends on the concentration (dose) and time. Therefore, at concentrations higher than 20 µg/ml and also over time, the vital activity of cells decreased.
Discussion & Conclusion: Based on the results obtained in this study, the use of magnetic zinc ferrite nanoparticles (coated with chitosan) for targeted drug delivery to the target tissue was suggested. The unique properties of these drug-carrying nanoparticles, such as good magnetic field response, good particle size, and low toxicity, enable the physician to have more precise control over targeted drug delivery to the target tissue.
