Background and Objective: Systemic lupus erythematosus (SLE) is an inflammatory multi-system disease with an unknown origin. In patients with lupus disease cardiovascular events is an important cause of mortality and morbidity. This study carried out to measurement of high sensitivity C –reactive protein (HsCRP) and homocysteine in patients with SLE and their relation with diseases activity and cardiovascular risk factors.

Materials and Methods: This case control study carried out on 60 patients (55 females and 5 males) with lupus disease which referred to Clinical Research Center of Rheumatology, Mashhad, Iran and 30 controls (26 females and 4 males) during 2007-08. Information of subjects were gathered using SLEDAI questionare. HsCRP and homocysteine of subjects were measured. The level of low density lipoprotein (LDL), Triglycerid, hypertension and Body mass index (BMI) was assessed. Systemic lupus erythematosus activity was assessed by using SLEDAI so that if the score was higher than 10, lupus was called as active disease.

Results: Mean age was 28.8±10.3 and 33.8±9.13 years in SLE and control groups respectively. The mean of HsCRP in SLE patients were 3±2.42 mg/dl versus in controls were 1.58±2.1. The serum level of homocysteine were 12.3±1.93 µmol/L and 24±8.13 µmol/L in SLE patients and controls (P<0.001). Mean disease activity was 15.37. There was no any associtation between homocysteine and HsCRP and disease activity. LDL, Triglycerid, hypertension had significant association with homocystein (P<0.05). BMI and Triglycerid had significant association with HsCRP (P<0.05).

Conclusion: This study showed that there is no linear significant corrolation between homocysteine, HsCRP and disease activity, but there is significant corrolation between increase of homocysteine and HsCRP and cardiovascular risk factors.

Background and Objective: The Clostridium botulinum is one of the most important causative of food poisoning. Spores of Clostridium botulinum spread out in the soil, the sea sediments, the marine environments and the marine animals. In recent years use of the marine food products like as fish and cultured fish are elevated. The aim of this study was done to compare between processing and non processing fish infected by predominant type of Clostridium botulinum.

Materials and Methods: This descriptive study was done on the 146 samples of fish in two species of processed and non prosecced that collected from Gilan province in Iran during 2008. These samples included the Liza auratus Fish (45 processed fish and 28 non processed fish) and the Salmo Trutta caspius Fish (34 processing fish and 39 non processing fish). The samples examined according to the APHA2000 and FDA2003 protocols. Data Analyzed with SPSS-13 and Chi-Square test.

Results: 16 (11%) of samples (13% of the processed fish and 7.5% of non processed fish) were confirmed that infected by Clostridium botulinum. Also the dominant type of exotoxin was Type E. The Type E exotoxin was determined from 11 of the samples (6 processed fish and 5 non processed fish).

Conclusion: This study showed that fish are infected by Clostridium botulinum special the type E. also use of fish in bad preparation (half cooking and add material in its stomach) may cause the food poisoning.

Background and Objective: Glaucoma is one of the most important cause of blindness wordwide. Exact determination of intra ocular pressure is important for the diagnosis and decision making about glaucoma treatment. Central corneal thickness is considered as effective factor on intra ocular pressure and visual field defect. This study was carried out to determine the relationship between central corneal thickness, intra ocular pressure and visual field in normal tension and primary open angle glaucoma. Materials and Methods: This descriptive study was carried out on 45 eyes with normal tension glaucoma and 45 eyes with primary open angle glaucoma in Al-Zahra ophthalmology hospital in Zahedan, Iran during 2010. Intra ocular pressure and central corneal thickness were measured by Goldman tonometer and pachymeter and visual field exanimated by Humphrey perimeter. Data were analyzed using SPSS-16, paired t-test, ANOVA, Mann–Whitney and Pearson corlateion tests. Results: There was significant correlation between central corneal thickness and intra ocular pressure (r=0.309, P<0.05). A significant difference was detected in intra ocular pressure between two type of glaucoma (P<0.05). Mean value of central corneal thickness in patient with mild visual field defect was higher than severe visual field defect but there was not significant statistical difference between central corneal thickness and visual field defect in subjects with glaucoma. Conclusion: This study indicated that increasing corneal thickness is accompanied with intra occular presure.

Background and Objective: Sleep is an important component of the circadian cycle is associated with the restoration of the physical and mental faculties. Physical activity is one of the confounding factors in improving sleep quality. This study was done to determine the effect of physical activity on quality of sleep in female students.

Methods: This cross-sectional study was conducted on 370 female students in Zabol University in south-east of Iran. Demographic data through a questionnaire were collected for each subject. Sleep quality and physical activity of subjects were recorded using standardized questionnaire Pittsburgh sleep quality index (PSQI) and physical activity Beck test. Subjects according to physical activity divided into active and inactive groups.

Results: Poor sleep quality was seen in 25.2% and 67.4% of active and inactive students, respectively. Mean of Sleep quality in both groups active 5.73±3.22 and inactive  7.21±3.75 was inappropriate but sleep quality in active females was higher than inactive females (P<0.05). A favorable condition for the quality of sleep was seen in 65.7% of the active group with BMI<25 and only 9.1% of students BMI was more than 25. In inactive students, 60.8% of subjects with BMI<25 had poor sleep quality. Both levels of BMI, sleep quality was significantly different between the groups, but this difference was higher in the active group (P<0.05).

Conclusion: Poor sleep quality was seen in high percentage of female students and physical activity influences the quality of sleep.

Background and Objective: Nonalcoholic fatty liver disease is the most common cause of liver disease worldwide and it is defined as a disorder of excess fat accumulation in the liver. This study was done to determine the prevalence of fatty liver among overweight, obese and normal children.
Methods: This historical cohort study was conducted on 90 children ages 5 to 13 years old in Taleghani pediatric theching hospital in Gorgan, north of Iran during 2014. Subjects according to Body Mass Index (BMI) classified into obese (95%>BMI), over weight (85-95% BMI) and normal (5-85% BMI). Childern were matched for age and sex. Liver enzymes (ALT Alanine aminotransferase and AST (Aspartate aminotransferase) and lipid profile includingTriglyceride: TG (High Density Lipoprotein: HDL and (Low Density Lipoprotein: LDL were measured and fatty liver evaluated based on sonographic parameters by a radiologist who didnot know children's BMI.
Results: The prevalence of fatty liver was 23.3% in obese children that was non- significantly higher than normal (16.7%) and over weight (16.7%) children. The prevalence of fatty liver was not significantly different between two sexes. AST was significantly higher in children with normal BMI in compared to obese and over weight children (P<0.05). The highest and lowest level of cholesterol was seen in obese and normal children (P<0.05).
Conclusion: This study showed that the prevalence of fatty liver non-significantly was higher in obese children in comparision with normal and over weight children.
