Stress responses have been excited by the painful stimuli, after induction of anesthesia and during the operation. In order to reduce these responses, it will be useful to select the type of anesthesia. Based on this fact, two groups of patients (Every group had 50 patients) were selected randomly. All patients are older than 18 years old and were chosen according to America Society of Anesthesiologist, class I, II, and were candidated for cataract surgery. Propofol were used for induction and maintenance of anesthesia In group 1 (TIVA group). In group 2 (Balance anesthesia), Sodium Thiopental induced anesthesia and the combination of N2O and Halothane were used for maintenance of anesthesia, respectively. Blood Glucose in two groups was measured before induction of anesthesia that all were in normal range (80-120 mg/d). Then after induction, incision and 30 minutes after start of surgery, blood Glucose was measured again and deviation from basal level were classified in three categories as: <10%, 10-20%, >20%. The results demonstrated meaningful difference between two groups, statistically (Chi-square, P<0.001). Increasing the blood Glucose in group 2, in three stages, was more than group 1. Blood Glucose level was increased about 20% from its basal level, in the majority of group 2 (32% after induction, 64% after incision, 62% 30 minutes after start of surgery). But, this amount of increasing in group 1 was detected as follow. 16% after induction, 16% after incision, 12% 30 minutes after start of surgery. It is possible that in TIVA group’s, control of blood Glucose and stress responses better than balance anesthesia group’s. The comparative measurements of catecholamine level in both groups would be the next investigations.

Background&Objective: Due to side-effects of diabetes mellitus in pregnancy, the rapid diagnosis and its treatment is very important. The aim of this study is to determine gestational diabetes mellitus (GDM) incidence in pregnant women. Materials&Methods: This survey is an analytic cross sectional study that evaluated 401 pregnant women in Babol Obstetrics Clinic. A Glucose Challenge Test (GCT) was done for all of the high risk women for diabetes in the first trimester and for other pregnant women in 24-28 gestational weeks. If GCT was positive (Blood sugar>135 mg/dl one hour after oral administration of 50gr Glucose), then a Glucose Tolerance Test (GTT) was done. For women with a positive GTT, the diagnosis was GDM. Results: In 401 pregnant women with a mean age of 24.69±5.31 four patients had overt diabetes (1%). In another 397 women, a GCT was done and 44 women (11% of all patients) had a positive GCT and 19 patients (4.7% of all patients) had GDM of those with GDM 26.3% need insulin therapy in addition to a diabetic diet. We noted there was also a positive relation between age and impaired GCT (P<0.05). Conclusion: GCT is recommended as screening test in 24-28 gestational weeks for all pregnant women.

Background and Objective: Adiponectin is an adipocyte-secreted hormone. Low levels of Adiponectin may indicate the insulin resistance and development of diabetes. The regular exercise therapy induces insulin resistance to be reduced. Glucose uptake increase in muscles, increased adiponectin levels and decreased of HbA1c in diabetic patients. This study was designed to evaluated the effect of down-hill and up-hill running exercises on the adiponectin and serum glucose in type-2 diabetic patients. Materials and Methods: This clinical trial study was conducted on 28 patients (13 male and 15 female), age 40 to 60 years, with type-2 diabetes, in neuromuscular rehabilitation research center, Semnan, Iran during 2009. Participants were assigned randomly in one of the two experimental groups, eccentric or concentric exercise using treadmill. Before and after control and intervention period, glucose, HbA1c and adiponectin serum were measured in both groups. Data were analyzed using SPSS-18, Kolmogorov-Smirnov, Repeated Measures ANOVA, Tukey and independent t tests. Results: Eccentric and concentric exercise significantly decreased glucose, HbA1c and also increased adiponectin levels (P<0.05) in type-2 diabetic patients. However, eccentric exercise also significantly reduced glucose and HbA1c and increased adiponectin levels compared to the concentric exercise (P<0.05). Conclusion: This study showed that eccentric exercise are more effective than concentric exercise to reduce and control the blood glucose level and improve serum adiponectin in type-2 diabetes mellitus patients.

Background and Objective: Leptin has a key role in obesity and type 2 of diabetes. This study was done to compare the effects of eight weeks aerobic and combined training on serum levels of leptin and glucose in type 2 diabetic men. Method: This clinical trial study was performed on 24 men with type 2 diabetes whom reffered to Taleghani Hospital in Kermanshah, West of Iran during June to August 2012. The patients were randomly divided into 3 groups including aerobic training, combined training (aerobic and resistance training) and control groups. Training protocols included three 1-hour sessions per week for eight weeks. Subjects in the control group did not participate in any physical activities. Serum levels of leptin and glucose were measured 48 hours before and 48 hours after intervention as fasting values in pre-and post-tests. Results: There was no significant difference between groups at pre-test for serum levels of leptin and glucose. After intervention, serum level of glucose in the aerobic group and serum level of glucose and leptin in the combined group were significantly reduced in compared to the controls (P<0.05). Conclusion: Aerobic and combined training with beneficial effects on the sera glucose level are recommended for patients with type 2 diabetes. However, combined training, regarding reducing leptin level seems to be more useful for these subjects.

Background and Objective: Accumulating evidence indicates a relation between aerobic capacity and glucose concentration, although the molecular mechanisms of this relationship are not fully known yet. This study was done to determine the effect of effect of 12 weeks aerobic exercise training on aerobic capacity and glucose concentration in obese men. Methods: In this quasi-experimental study, thirty two adult obese males were divided into interventional and control groups. Anthropometrical indexes, fasting blood glucose and insulin, resting heart rate and aerobic capacity (VO2max) were measured before and after a 12 weeks aerobic exercise in the interventional and control groups. Beta cell function was calculated by fasting glucose and insulin. Results: Long time aerobic exercise led to significant reduction in glucose (112±10 vs. 85±11 mg/dl), anthropometrical indces, BMI (28.44±2.29 vs. 33.24±5.14), increase in VO2max (26.12±4.11 vs. 32±6.41 ml/kg/min), beta cell function (83±23 vs. 181±35) and in interventional group in comparision with controls. A significant correlation was found between the changes in VO2max with changes in beta cell function and glucose level, these correlations were independent of BMI. There was no significant change in insulin level between intervention and control groups. Conclusion: Increased aerobic capacity or cardiovascular fitness by exercise training improve beta cell function of glucose concentration in obese men.

Background and Objective: Diabetes mellitus is the most common type of metabolic diseases which is characterized with hyperglycemia due to implicit or relative insulin deficiency. Diabetes mellitus is acutely related to obesity. Agouti-related protein (AGRP) has 132 amino acids and increases appetite in humans. This study was done to determine the effect of eight weeks aerobic exercise on plasma level of agouti-related protein, glycated hemoglobin and glucose in non-active type II diabetic women. Methods: In this quasi-experimental study, 30 female diabetic patients were divided into exercise and control groups. The training program was performed 3 sessions a week in course of 8 weeks, each session was last for 60 minutes, and the controls did not have any exercise. The plasma level of agouti-related protein, glycated hemoglobin and glucose were measured. Results: There was no significant alteration in the level of AGRP, HbA1c and glucose in either exercise or control groups. There was no significant relation between AGRP with glucose, AGRP with HbA1c and HbA1c with glucose in the exercise and control groups. Conclusion: Eight weeks of aerobic exercise is not enough for making any changes on plasma level of AGRP, HbA1c and glucose in non-active type II diabetic women.
