Abstract
Background: A high dietary lipid intake is an important mediator of cholesterolemia and cardiovascular disease. Oils such as Sesame oil are not thought to contribute to such complications although information on the subject seems to be spare and contradictory. Since the ground seed of Sesame or “Ardeh” is commonly used in certain parts of this country (Iran), so its effects on the serum lipid profile of the rats have been investigated.
Methods: The study was performed on six groups of male Wistar albino rats (10 in each group) weighing 300-350 gr. Ardeh was prepared by grinding the seeds after they had been roasted at 60ºC. To prepare a high cholesterol diet, 1% cholesterol and 0.5% cholic acid was added. Group 1 consumed the ordinary diet 2 the ordinary diet plus Ardeh (24%), 3 the ordinary diet plus sunflower oil (10%), group 4 the high cholesterol diet, 5 the high cholesterol diet plus Ardeh, and group 6 the high cholestrol diet plus sunflower oil, all for 30 days. Blood samples were obtained and sera were used to determine the lipid profile
Results: The results of the study revealed that addition of Ardeh to the ordinary diet decreased serum cholesterol level significantly (P<0.01) in group 2 (38.2±2.3 mg/dl) as compared to the group 1 (49.9±5.9). Ardeh and sunflower oil had a similar effect on the groups, which consumed the high cholesterol diet. Ardeh also reduced the triglyceride level significantly (P<0.01) in group 2 (65.1±7.6 mg/dl) as compared to group 1 (106.3±15.1). Presence of both Ardeh and sunflower in the diets failed to affect HDL, but VLDL levels in group 2 (13.0±1.5 mg/dl) were significantly (P<0.01) lowered as compared to group 1 (21.2±3).
Conclusion: From the results of this study it appears that Ardeh can have a beneficial effect on lipid profiles and its addition to the diet is recommended.

Abstract
Background: The aim of this study was to determine the level of agreement between the impaired fasting glucose (IFG) and abnormal glucose tolerance before and after application of the new IFG definition and to evaluate the impact of adding common clinical data on this agreement.
Methods: A cross sectional population based study was carried out in an Iranian urban population which enrolled 8766 men and women over 20 years. Fasting and 2-hour plasma glucose were measured in all subjects excluding those with previously diagnosed diabetes and fasting plasma glucose ≥126 mg/dl. The diagnostic parameters and kappa coefficient between the previous and revised definitions of IFG for detecting impaired glucose tolerance (IGT) and dysglycemia (IGT and diabetes) were calculated. Logistic regression and ROC curve analysis were used to determine the independent clinical risk factors and their optimal cut-points associated with IGT and dysglycemia.
Results: After using the new criteria, sensitivity of IFG for detecting IGT or dysglycemia increased but specificity and positive likelihood ratio (LR+) decreased and the κ slightly improved (0.16 to 0.29 for IGT and 0.24 to 0.35 for dysglycemia). Adding the clinical data to the revised criteria considerably improved the agreement between IFG with IGT and dysglycemia (κ increased from 0.286 to 0.470 for IGT and from 0.354 to 0.574 for dysglycemia). This also increased the LR+ from 3.86 to 14.5 and from 4.46 to 17.4 respectively for detecting IGT or dysglycemia.
Conclusion: The new IFG definition in combination with common clinical risk factors most likely predicts IGT and dysglycemia.

Abstract
Background: Metformin is used in treatment of non-insulin-dependent diabetes mellitus (NIDDM). The present study was aimed to study the pharmacokinetic and pharmaco-dynamic of metformin 500 mg tablet in healthy volunteers.
Methods: The test and reference metformin hydrochloride 500 mg tablets were administered to 12 healthy volunteers in a cross-over study. Metformin serum concentration and decrease in blood sugar levels (dBSL) were used for study of pharmacokinetic and pharmacodynamic.
Results: There was no correlation between phramacodynamic and pharmacokinetic para-meters. Also there was no increase in dBSL-(AUC0-12) with increase metformin serum concentration-time. The results of our study show that both products could be bioequivalent according to serum concentration and not blood sugar data.
Conclusion: There was no concentration – effect (dBSL) correlation for both products. Metformin didn’t decrease the blood glucose in healthy volunteers. In some volunteers there was no increase in blood sugar after meal and dextrose 20% oral solution administration which could be related to decreased absorption of glucose from gastrointestinal tract caused by metformin.

Abstract
Background: Use of medicinal plants for attenuation of hyperglycemia and restoration of lipids to normal levels is very important. The effect of oral administration of Vaccinium myrtillus (VM) on serum glucose and lipids in diabetic rats was investigated.
Methods: Female Wistar rats were divided into 4 groups: control, VM-treated control, diabetic, and VM-treated diabetic groups. The treatment groups received oral administration of plant-mixed food (6.25%) for 4 weeks. Serum glucose, triglyceride, total cholesterol, LDL- and HDL- cholesterol levels were determined before the study, and at 2nd and 4th weeks after the study.
Results: Serum glucose level in diabetic group increased 2 and 4 weeks after the experiment as compared to data one week before the study (P<0.001) and VM treatment of diabetic rats did have a significant hypoglycemic effect (P<0.01). In addition, triglyceride level in diabetic group increased 4 weeks after the experiment in comparison with related data one week before the study (P<0.05) and there was a significant lower level of triglyceride in VM-treated diabetic rats (P<0.05). Furthermore, there was no significant changes regarding serum total cholesterol, HDL- and LDL- cholesterol levels in treated diabetic group as compared to untreated diabetic group.
Conclusion: Oral administration of VM has a significant hypoglycemic effects and leads to an appropriate changes only in triglyceride level.

Abstract
The P-Value cannot present a complete measure of association in medical studies considering the
association between categorical variables. In such situations, measures are required to reveal the
clinical importance of relation along with their statistical significance, as the effect size. This paper
aims to introduce the measures of associations for categorical variables and inferences about them in
these studies. Principles and method of calculating measures of associations and inference about them
including confidence interval and hypothesis testing were presented to assess the relationship between
qualitative variables for all types of medical studies taking into account relevant considerations.
Additionaly, the method of reporting of findings were introduced in the context of contingency tables.
To investigate the relationship between two binary qualitative variables, should be used the Odds
Ratio in cross-sectional or case-control studies, the relative risk in cohort studies, and prevalence ratio
in cross-sectional studies and risk difference in all type of studies along with their confidence intervals
and/or their significance tests considering the independent or related groups of studies. Additionally,
for bigger than 2 by 2 tables, the method of calculating of above mentioned measures considering a
reference category and other measures such as Phi, Crammers V, contingency and uncertainty
coefficients , Lambda, Gamma, Summers D, Kendals tau-b and tau-c would be recommended. In each
of these situations, based on research based examples, calculations of tests were performed and their
results were presented. To investigate the relationship between a set of risk factors and binary and
multi-category qualitative variables, the introduced analyses are recommended considering the
situation and purpose of the proposed study.

Abstract
Background: Diabetes is considered as one of the health problems in all societies. Exercise training
and drug interventions, especially herbal medicines, consider as approaches to improving diabetes.
The objective of this study was to investigate the effect of 6 weeks of aerobic training and Pistacia
atlantica extract consumption on pancreatic β-cells function in streptozotocin-induced diabetic rats.
Methods: Thirty six male Wistar rats divided into five groups: normal control, diabetic control,
diabetes+aerobic training, diabetes+extract, diabetes+aerobic training+extract. Diabetes was induced
by intra-peritoneal injection of streptozotocin (40mg/kg). Exercise program was include 6 weeks of
aerobic training on a treadmill (5 sessions per week, 40 minutes per session, with a speed of 20m/min
and 5% incline). Extract groups were received Pistacia atlantica extract based on body weight, at the
end of each training session. After 6 weeks of aerobic training and Pistacia atlantica extract
consumption, plasma glucose and insulin levels were measured for determination of β-cells function
(HOMA-B). Data were analyzed via ANOVA, with a significant level P<0.05.
Results: HOMA-B index in diabetic control group was significantly higher than normal control group
(P=0.0001). Also mean of HOMA-B index in diabetes+extract and diabetes+exercise training+extract
groups was significantly lower than diabetic control group (P values 0.003, 0.001 respectively) and
between mean of HOMA-B index in diabetic control group with diabetes+aerobic training group were
observed no significant differences (P=0.052).
Conclusion: The results of this study showed that Pistacia atlantica extract consumption, alone and
along with aerobic training leads to significant improvement in pancreatic β-cells function in diabetic
rats. Also extract consumption along with aerobic training in comparison to training alone has had
greater impact on the improvement of pancreatic β-cells function. It seems that aerobic training along
with the use of specific herbal plants can be considered as a complementary therapy in improvement
of diabetics.

Abstract
Background: Diabetes is a kind of metabolic disorder characterized by hyperglycemia, caused by defect in insulin function, secretion or both. In chronic hyperglycemia different tissues and organs, such as thyroid gland underwent histophysiological alterations. The aim of the present study was to compare the effects of type 1 and type 2diabetes on the serum levels of biochemical factors and histological changes in the thyroid gland in male Wistar rats.
Methods: After induction of type 1 diabetes (Alloxan 135 mg/kg BW) and type 2diabetes (10% fructose administrated through drinking water for 8 weeks) all rats were kept for 2 months. Blood samples were collected at the beginning and in the middle and at the end of experiment for biochemical factors analysis. After that, the thyroid gland of all rats were removed and processed for histological preparation. Then the HE stained sections were examined for thyroid gland volume and follicular surface density measurements, using Cavalieri’s Principle and stereological method, respectively.
Results:The results showed an increase in surface density and a decrease in thyroid volume in type 1 diabetic and type 2 diabetic groups, when compared with control. Furthermore, in type 1 diabetic group, the Triglycerid and Cholesterol levels increased and LDL level decreased, while in type 2 diabetic group, LDL and HDL levels slightly decreased. These results reveal that type 1 and type 2 diabetic conditions probably cause hypo- and hyper activity of thyroid gland, respectively.

Abstract
Background: Exercise is very important factor in control of diseases. It also has been suggested that angiogenesis inhibitor factor is controlled and angiogenesis simulative factor is intensified on those who are suffering diabetic and doing physical activity. This study is aimed to evaluate the effect of Eight-week Resistance Training on unbalanced Angiogenesis in Diabetic male rats.
Methods: Twenty-four diabetic male Wistar rats were divided into two groups of control and training. Resistance training protocol includes one set of 10 times per day climbing the ladder suffering a weight connected to each rat tail [with respect to the maximum volume carrying each rat] for 3days a week and for 8 weeks. After 48 hour of the last training session, blood samples were taken from rat's hearts and VEGF, NO, glucose and insulin were determined regarding to serum sample taken. Analytical statistics examined with the use of SPSS16 software and considering α< 0.05.
Results: this study of Eight-week Resistance Training resulted no significant increase on VEGF [P=0.776] and NO [p=0.946] in diabetic rats serum but there was a significant decrease in blood glucose [p=0.001] however, no significant difference was observed in insulin level between the groups [p=0.93].
Conclusion: Despite resistance training appears to improve glucose levels in diabetic rats it has no positive effect on the stimulation factors of angiogenesis.

Abstract
Background: Given diabetes mellitus has an adverse effect on spermatogenesis and male fertility, the aim of the present study was to investigate the effect of L-carnitine administration on spermatogenesis and testicular structure in diabetic rats induced with Stereptozotocin.
Methods: In this experimental study, fifteen rats were randomly divided into 3 groups: control group was received citrate buffer. Case group was diabetic rats that received 40 mg/kg carnitine for 16 days. Third group was diabetic rats that did not receive carnitine. After sixteen days, morphometric study was performed. Besides, index of testicular weight was obtained. Then, data were analyzed using SPSS software and ANOVA.
Results: In testicular sections of diabetic rats were observed a disruption and deformity in first layer of somniferous tubules. Statistical analysis showed a significant difference in carnitine group when compared to the control group (P<0.05). There was a significant difference between weight of diabetic rat compared to the control group (P<0.001). Besides, there was the most ratio of testis index in control group.
Conclusion: Our finding showed that short-term L-carnitine administration was affective on the diameter and thickness of seminiferous tubules. Hence, L-carnitine treatment may cause an improvement in spermatogenesis of diabetic men.

Abstract
Background: Evidences exist that abdominal obesity is a difference in terms of body mass index (BMI) and these two factors have different effects on bone density. This study examined the association between body mass index, obesity, the history of fracture and bone mineral density in Iranian population. There exist evidences on the effects of body mass index (BMI) and abdominal obesity, and the role of this two factor on bone density. This study examined the association between body mass index, abdominal obesity, and the frequency of fracture with bone mineral density in Iranian population Methods: The Study was done as a cross-sectional, population-based retrospective study. People over 18 years were included in the third part of the IMOS project (National comprehensive plan for the prevention, diagnosis and treatment of osteoporosis). Abdominal obesity was calculated based on waist to hip ratio that was considered positive > 0.95 in men and 0.85 in women. The linear regression test was used to examine the relationship between BMI and abdominal obesity with bone densitometry. Results: A total 2019 cases (717 men, 1302 women) with 41.85 ± 13.95 years enrolled in this study. Almost, 36% of men and women were obese based on waist circumference. Correlation coefficients of BMI with bone density were equal 0.236 for Hip, 0.133 for femoral neck, 0.138 for lumbar spine. Waist to hip ratio was inversely associated with bone density. Bone densities in the hip and lumbar spine, in individuals with a positive history of wrist fracture were significantly lower than those with a negative history of fracture. Conclusion: contrary to the total body fat, abdominal obesity based on waist to hip ratio is inversely associated with bone density. In other words, abdominal obesity increases the risk of fractures by reducing the bone density without creating protective shield of adipose tissue in vulnerable areas.

Abstract
Background: The process of wound healing is impaired in diabetes. Many efforts have been made to accelerate the wound healing process. Long time healing effect of a herbal complex containing Aloe vera, Myrrh, dragon’s blood and henna has been observed in wound healing, But sufficient scientific evidence of how the mechanism of action of this compound is absent in diabetic wounds Whereas the effect of each of them separately in several studies on ulcers observed. The purpose of this study was to evaluate the effect of topical herbal (briefly called Herbalin) on wound healing in diabetic rats.
Methods: The diabetic rats were divided into two groups: control (treated with Vaseline as a vehicle) and experimental (treatment with herbalin) were included. In each class, all wound round with a diameter of2cmwas made on the dorsal surface of diabetic rats. Wound measurement and histopathological parameters such as the formation of re-epithelization, granulation tissue formation and the average thickness of the epithelium at intervals of7, 14and21dayswere evaluated. Strain epithelium on day 14andthe wound length atday21was evaluated in the terminal phase.
Results: In macroscopic study, the Herbalin treated wounds were found to healing much faster and the day 14 has considerable change compared with control group (P<0.05). In microscopic study, in all cases of the Herbalin treatment groups showed a significantly increased as compared with controls (P<0.05).
Conclusion: According to the results, the herbal complex, possibly by accelerating the formation of granulation tissue and epithelium and thickening of the epithelium has an important role in wound healing in diabetic and reduces the time required for healing.

Abstract
Background: Type 2 diabetes is a major metabolic disorder. This study was aimed to evaluate the effect of probiotic soymilk fermented with Bifidobacterium lactis and containing omega-3 on hematologic, oxidative stress, anti-oxidant and inflammatory parameters in type 2 diabetic rats.
Methods: In this experimental manipulation study 65 rats were divided into five groups. Type 2 diabetes was induced by a single injection of streptozotocin and nicotinamide. Normal control (NC) and diabetic control (DC) rats received 1 mL/day of distilled water, and three groups of diabetic rats were administered 1 mL/day of soymilk (SM), fermented soymilk (FSM) and fermented soymilk fortified with omega-3 (FSM+omega-3) products by oral gavage for 28 days. Hematologic, oxidative stress, anti-oxidant and inflammatory parameters were measured at the end of experiment.
Results: At the end of experiment, in all treated diabetic rats compared with the DC group, red blood cell (RBC), hemoglobin (Hb), hematocrit and superoxide dismutase (SOD) concentrations increased significantly (p<0.05), and malondialdehyde (MDA) concentrations reduced significantly (p<0.05). The reduction of MDA and increasing in Hb, RBC, hematocrit and SOD concentrations in the FSM+omega-3 group was more than two other groups. In the FSM+omega-3 group, high sensitivity C-reactive protein (hs-CRP) concentrations compared with the DC and FSM groups were significantly lower (p<0.05).
Conclusion: The experiments suggest that combining soymilk, probiotics and omega-3 may be beneficial for the reducing oxidative-stress in type 2 diabetes.

Abstract
Background: Diabetic foot ulcers are important topic in diabetes care. Diabetes is one of the most common metabolic diseases of endocrinology. Raspberry (Rubus fruticosus) has anti-inflammatory, anti-septic and anti-oxidant effects. The aim of present study is healing effects of raspberry extract on the regeneration process of skin wounds in control and diabetic rats.
Methods: In this study, 48 adult male rats were divided into four groups (n=12 each) including: control group (non-treated and non-diabetic rats), sham (eucerin-treated diabetic rats), experimental1 (non-treated diabetic rats) and experimental 2 (raspberry-treated diabetic rats). Diabetes was induced by 55 mg/kg Streptozotocin (STZ) in three groups of rats. A wound with 3 cm length was created on the skin of back side of animals in all groups. The experimental 1 group was treated by eucerin and experimental 2 groups were treated by raspberry extract two times in a day. Microscopic and macroscopic studies were performed on wound healing process on days of 3, 5, 7, 14 and 21.
Results: The findings showed that sham and experimental 1 group had later healing effect comparing with control group. The speed of wound healing in raspberry extract-treated rats (experimental 2 groups) had significantly increased in comparison with control group and the wound surface area has been significantly decreased in comparison with all other groups (P ≤ 0.05).
Conclusion: It seems that topical application of raspberry extract can accelerate the wound healing in diabetic rats and materials in raspberry extract stimulate the collagen synthesis, faster wound contraction and angiogenesis.

Abstract
Background: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease is increasing in adults and children worldwide. Obesity, insulin resistance or diabetes type II, hyperlipidemia and hypertriglyceridemia plays a major role in the epidemiology of this disease. Cytokeratin 18 (CK-18) the major intermediate filament protein in the liver is a marker of increased hepatocyte apoptosis. The aim of this study was to determinate CK-18 level as a marker of hepatocyte apoptosis and paraoxonase as a biochemical marker for lipid peroxidation.
Methods: This case–control study was done on 51 subjects with confirmed NAFLD by ultrasound and 30 healthy individuals. CK-18 is proposed as a biomarker alternative cell death. The serum was used for measurement of the apoptosis-associated neo-epitope in the C-terminal domain of CK-18 by the M30-Apoptosense ELISA kit. The M30 detection antibody recognizes a neo-epitope mapped to positions 387 to 396 of CK18, so called CK18-Asp396 that is only revealed after caspase cleavage of the protein and is postulated as a selective biomarker of apoptosis. Serum PON1 activity was assayed using a synthetic substrate. Paraoxon substrate (diethyl-p nitrophenylphosphate), was deliberated using the increase of absorbance at 412 nm at 37 ◦C.
Results: There were significant differences regarding serum cytokeratin 18 (p=0.005), paraoxonase activity (p=0.03), triglycerides (p=0.04) and low-density lipoprotein (p=0.04) between NAFLD and healthy subjects. Between CK-18 and paraoxonase with the early stages of fatty liver disease are associated.
Conclusion: This study suggests that serum levels of cytokeratin 18 can be useful in predicting non-alcoholic fatty liver disease. Paraoxonase activity (PON1) should be considered a biochemical marker of lipid peroxidation and the need for follow-up in patients with NAFLD
Keywords: Non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), Cytokeratin 18 (CK-18), Paraoxonases

Abstract
Background: Irisin was identified as a myokine secreted by exercise which plays an important role in energy metabolism and regulation of metabolic diseases such as diabetes. The aim of the present study is to investigate the effects of high intensity interval exercise (HIIE) and moderate intensity continuous exercise (MICE) on serum irisin and Subcutaneous UCP-1 in diabetic male rats.
Methods: In this study, 29 diabetic Wistar rats (12 week- age, 220-240 gr- weight) were assigned to 5 groups: immediately and 2 hours after high intensity interval exercise (HIIE0, HIIE2), immediately and 2 hours after moderate intensity continuous exercise (MICE0, MICE2) and control (C). Both MICE groups performed on the treadmill with intensity 60-65% vo2max for 40 minutes and both HIIE groups with intensity 90-95% vo2max in the 12 interval-one minute period and 1 minute rest intervals. ELISA was used to measure serum irisin and subcutaneous fat UCP-1. One-way ANOVA and Tukey post hoc test has used to data analysis, the level of significance has been considered at P≤0/05.
Results: Data analysis showed serum irisin levels in the HIIE0 group and subcutaneous fat UCP-1 in the HIIE2 significantly increased compared to the control group (p˂0/05). However, there was no significant difference between other research groups (P>0/05).
Conclusion: It seems high intensity of exercise had important roles in significant changes of serum irisin levels and subcutaneous fat UCP-1in diabetic rats.

Abstract
Background: In recent years, waist and hip circumference measurements simultaneously used as anthropometric factors to determine the prevalence of overweight and obesity in adults, in addition to Body Mass Index. Some studies have confirmed the relationship between the above mentioned factors and the hematological parameters of cardiometabolic disorders. This study aimed to determine the association between anthropometric factors and hematological factors in 25-60 years old couples of Babol, Mazandaran.
Methods: This cross-sectional descriptive study was conducted in spring 2014, on research population of 25-60 year old couples who were selected by random cluster. Data collected through a researcher-made questionnaire containing about demographic variables, underlying factors, dependent variables; its validity and reliability were confirmed. The collected data were analyzed by SPSS18 software.
Results: Men’s BMI had significant direct relationship with systolic and diastolic blood pressure, fasting blood sugar, cholesterol and triglycerides (p<0.05). Women’s BMI had a significant direct relations with systole and diastole blood pressure, fasting blood sugar and triglycerides (p<0.05). There was a significant direct relationship between men’s and women’s Waist/Hip Ratio (WHR) with systole and diastole blood pressure, fasting blood sugar, cholesterol and triglycerides (p<0.05). There was a significant direct relationship between men’s and women’s anthropometric indices (apart from the BMI) associated with serum biomarkers of cardiometabolic disorders (p<0.05).
Conclusion: The results showed that increased BMI and WHR in couples, increases the amount of cardiometabolic serum biomarkers and may directly and indirectly cause the risk of chronic diseases.
