Abstract
Background: Studies in different species indicate that a variety of different inhibitors may influence myometrium during pregnancy and withdrawal of one or more of them leads to the onset of labor pain. Hence, this study was done to investigate the association between parathyroid hormone-related peptide1-34 (PTH-rp1-34) and labor pain. Materials and Methods: This study was a case-control one. Plasma PTH-rp1-34, PTH, total calcium, phosphorous, magnesium, and alkaline phosphatase concentrations were quantified for 152 normal pregnant women at term (76 women at the onset of labor pain, as the case group and 76 women without labor pain, as the control group). The subjects had no pregnancy related complications. Results: The mean of plasma PTHrp concentrations in the group with labor pain (12.36±0.60 ng/ml) did not differ from that in the group without labor pain (13.57±0.63 ng/ml). The means of plasma PTHrp concentration amounts in the group with labor pain and the group without labor pain were 28.92±1.66 pg/ml and 31.88±1.64 pg/ml, respectively and there was no significant difference between the two groups. There were no significant difference in plasma calcium, phosphorus, magnesium, and alkaline phosphatase concentrations in the two groups too. Conclusion: In this study, the endocrinal role of PTHrp and the onset of labor pain was not confirmed.

Abstract
Background: Familiarity with different methods and medications in anesthesia and producing sufficient depth of anesthesia are very important in anesthesia practice. Due to the central analgesic and sedative effect of lidocaine in the presence of the sufficient blood level, it can be used for general anesthesia. This study was carried out to compare the effect of halothane with lidocaine infusion on BIS during maintenance of anesthesia.
Materials and Methods: In this randomized double-blind controlled clinical trial, 66 patients scheduled for elective inguinal herniorrahaphy were randomized into two equal groups. For maintenance, one group received halothane (1%) with O2-N2O and another group received lidocaine infusion (100 &mug/kg/min). BIS was checked every 5 minutes for half an hour. Statistical analysis of data was done by Chi-square and T-test through SPSS software. P-values less than 0.05 were considered meaningful.
Results: Mean of BIS was 65.72 in the lidocaine group and 56.7 in the halothane group during the first 30 minutes. There was a significant statistical difference between the two groups (p<0.05).
Conclusion: Mean of BIS in lidocaine group was higher than that in the halothane group. If this indicates the presence of a light level of anesthesia, increasing the dose of hypnotics and opioids leads to an increase in the depth of anesthesia. However, since there is not any device for monitoring the effect of opioids on the central nervous system and the level of anesthesia, simultaneous monitoring of BIS and hemodynamic parameters seems to be a more reasonable idea.

Abstract
Background: Diabetes mellitus is a common disease in human societies that dealing with its complications imposes enormous cost to the health system. The previous studies have shown that bone biochemical markers can be used for evaluation of bone metabolism in response to physical activity. The purpose of this study was to examine the effect of increasing 10-week aerobic exercise (AE) on serum osteocalcin, PTH and glycemic and anthropometric indices in postmenopausal women with type II diabetes.
Materials and Methods: In this semi-experimental study, 40 postmenopausal women with type II diabetes (40-60 years) as available subjects were selected and randomly assigned into two exercise (20) and control (20) groups. Exercise protocol was AE and walking activity for 10 weeks (3d/wk, 45 to 60 min/d with 45% to 60% HRRmax intensity). Blood samples were taken before and after exercise to measure serum variables. Data were analyzed by T-test and statistical significance criterion was set as p<0.05.
Results: AE makes a significant increase in osteocalcin levels and a decrease in insulin resistance index, insulin and fasting blood glucose in the experimental group (p<0.05). Changes in other variables such as PTH, HbA1c and anthropometric indices were not significant (p>0.05).
Conclusion: Due to the favorable effects of AE on osteocalcin and glycemic indices, it seems that this training method can be recommended as a non-invasive treatment for maintaining bone density and controlling blood glucose in diabetic patients.

Abstract
Abstract
Background: Hemodynamic changes during surgery are initially controlled by changes in dosage of anesthetics. Decreasing the dose of anesthetics in order to cope with hypotension during surgery may reduce the anesthetic depth and increases the chance of awareness. This study was designed to investigate the depth of anesthesia in patients whose anesthtics is prescribed by controlling blood pressure and is aimed to investigate the possibility of reducing the depth of anesthesia during surgery.
Materials and Methods: In this study, females candidate for hysterectomy underwent general anesthesia according to specific inclusion criteria enrolled in two types of intravenous (propofol) or inhaled (isoflurane) anesthesia. The dose of maintenance anesthetic drugs were increased or decreased during the operation by the anesthetist technician (blinded to the depth of anesthesia) according to specified protocol. At defined intervals, depth of anesthesia was recorded by the anesthetist . Mean of obtained data were analyzed.
Results: In addition to the weight and height similarity, there was no statistically significant difference in systolic, diastolic blood pressure and heart rate in two groups at intervals, between two groups. The median of recorded BIS, which showed depth of anesthesia, was not different in either of the two groups, and no patients during the operation reached the level of awakening and the number above 60.
Conclusion: The traditional method to control hemodynamic changes during surgery by changing the doses of maintenance drugs, does not result in severe changes in the depth of anesthesia and does not significantly increase the BIS to the awareness level.
