Abstract
Background: In recent years, studies have been conducted on the role of coenzyme Q10 in improvement of sport performance and also cardiovascular health. The present study investigate effect of coenzyme Q10 supplementation combined with swimming aerobic exercises on Heart Rate Deflection Point (HRDP) and VO2max in active women.
Materials and Methods: A number of 32 trained women with the average age of 21/25 ± 0.86 years and Body Mass Index (BMI) of 20/127± 1.06 kg/square meter were selected randomly and were divided into eight -member each groups: Control, Supplement, Supplement – Exercise and Exercise. The subjects participated in four-week consumption of coenzyme Q10 and swimming exercises (three sessions in a week).The consumption rate of coenzyme Q10 100 mg/kg/d was in the form of capsule that subjects took it during lunchtime. Before and after a four-week period, the subjects performed an incremental exhaustive test on treadmill, using respiratory gas analyzer to determine HRDP and VO2max. It should be noted that data analysis was conducted using One-Way Variance Analysis Test (ANOVA) in P<0.05 significant level.
Results: Based on paired T-Test results, despite HRDP had increased in each four groups but the significant increase was observed only among groups in VO2max (P=0.008) based on ANOVA Test (P<0.05).
Conclusion: Although positive changes were observed inside the group after passage of four weeks, coenzyme Q10 supplementation combined with swimming aerobic exercise had not any significant effect on HRDP only increased VO2max.

Abstract
Background: Due to high prevalence of vitrectomy surgery, and the importance of anesthetic technique in conducting an uncomplicated surgery, we decided to do this study.
Materials and Methods: This prospective randomized study was conducted on 80 patients 40-80 years old candidating deep vitrectomy sugery under general anesthesia that were categorized into II and III Class by American Society of Anesthesiologist (ASA). Patients were randomly allocated to two groups of 40 members. Anesthesia was induced in both groups in the same manner. For maintaining anesthesia, patients from I group receiVed 1.2% isofluran with 50% O2 in air at 4L/min and infusion of remifentanil (0.1 mg.kg-1.min-1). But in the P group, we used propofol up to 10mg/kg /hr with infusion of remifentanyl. Propofol and isoflurane in fusion was discontinued with the last surgical stitches, but remifentanil infusion continued in both groups until the eye was covered with shield. Hemodynamic variables were recorded just before the induction of anesthesia and in different time intervals till discharging of the patients from the recovery room. Then, data were compared.
Results: Results showed that there is a significant changes in propofol group compared to isofluran in deep vitrectomy surgery operations.
Conclusion: Hemodynamic changes are more significant in maintaining propofol anesthesia when compared with isoflurane.

Abstract
Abstract
Background: Up to now, there is no single opinion on how to control pain after surgery and clinical research in this area has been continuing. This study aimed to compare the effect of intravenous Acetaminophen, Dexamethasone and placebo on postoperative pain after cataract surgery under sedation and topical anesthesia.
Materials and Methods: In a clinical trial study, 120 patients undergoing cataract surgery under sedation and topical anesthesia were distributed into three equal groups. 10 minutes before the end of surgery, the first group received 0.01 mg/kg Dexamethasone, the second group received 15 mg/kg Acetaminophen and third group received the same volume on normal saline as placebo. Pain intensity and additional analgesic consumption were assessed during operation and recovery and compared between the three groups.
Results: In the three groups of Acetaminophen, Dexamethasone and control groups, 6, 10 and 18 patients had postoperative headache (16.7%, 27% and 47.4% respectively) and there was a significant difference between the three groups(p=0.014). Also, pain intensity was significantly higher in control group compared with other two groups from 30 minutes after arrival to the recovery room until 24 h postoperatively (p<0.05). Also, the incidence of headache was higher in Dexamethasone group compared with Acetaminophen group, but there was no statistical difference between the two groups in this regard (p>0.05).
Conclusion: Intravenous Acetaminophen administration is more effective than Dexamethasone and placebo to reduce pain and analgesic requirements after cataract surgery.

Abstract
Abstract
Background: Postoperative nausea and vomiting (PONV) is one of the most common complications in the patients undergoing strabismus surgery. The aim of current study was comparing supplemental 80% and 40% oxygen on reducing postoperative nausea and vomiting in the pediatrics undergoing strabismus surgery.
Materials and Methods: In this clinical trial study, 100 pediatric patients scheduled for strabismus surgery under general anesthesia were allocated randomly into two parallel supplemental 80% and 40% oxygen groups during surgery. PONV in patients was compared until 24hrs after operation.
Results: In the first 6hrs postoperatively, PONV in the supplemental 40% and 80% oxygen groups were 48.8% and 30.6% respectively, also were 20.8% and 12.2% in the 6 to 24hrs postoperatively. Therefore, there were no significant differences between both groups in regarding of PONV in 6hrs and 6 to 24hrs postoperatively (p values were 0.18 and 0.25, respectively).
Conclusion: According to our results, there is no any difference between 40% and 80% oxygen postoperatively in the pediatrics undergoing strabismus surgery.

Abstract
Background and Aim: There exists increased demineralization risk of enamel adjacent to fixed orthodontic attachments by cariogenic bacterias (e.g., Streptpcoccus mutans, Streptpcoccus sobrinus) and inadequate data about commonly used orthodontic cements. Thus, we evaluated the antibacterial effects of three common domestic and foreign orthodontic cements (Glass ionomer, Zinc phosphate, & polycarboxylate) on two cariogenic pathogens (S. mutans & S. sobrinus).
Methods & Materials: In this laboratory study, after culturing two standard strains of Streptococcus mutans and Subrinus bacteria and concentrating and diluting them, a direct contact test was used to evaluate the antibacterial properties of types of cement. The study groups (n=5) included the following: three types of glass ionomer resilience cement, Hoffman’s zinc phosphate and Hoffman’s polycarboxylate, and three glass ionomer cement, zinc phosphate, and carboxylate from Aria Dent factory in Iran. The acquired data were analyzed using SPSS v. 17.
Ethical Considerations: The present study was approved by Babol University of Medical Sciences (Code: MUBABOL.REC.1391.7).Results: In both types of culture media, containing Streptococcus mutans and Streptococcus subrinus bacteria, there was a significant difference between culture media containing 3 groups of cements respecting bacterial growth inhibition zone (P<0.001). In general, The mean diameter of the inhibition zone was greater in Iranian polycarboxylate, compared to its foreign counterpart (P<0.001).
Results: Regarding to zone of inhibition, there was statistically significant difference between three tested cements in both S.mutans and S.sobrinus culturing media (P<0.001). The mean diameter of inhibition zone was greater for Iranian polycarboxylate compared to its foreign counterpart (P<0.001).
Conclusion: Glass ionomer cement demonstrated better antibacterial effect compared to zinc phosphate and polycarboxylate cements. There was also greater antibacterial effect of three tested cements on S.sobrinus than S.mutans. Iranian polycarboxylate showed stronger inhibition on both mentioned bacterias compared to the foreign one.
