One of the major determinative of the outcome of the ophthalmologic surgeries, is how efficiency the anesthesiologist can lower the intraocular pressure (IOP) and prevent it from rising in response to such maneuvers as laryngoscopy and tracheal intubation. In our study, we have chosen Midazolam and Propofol for comparing their effects on IOP during induction of anesthesia, laryngoscopy and tracheal intubation, with the purpose of identifying the drug which can more effectively decrease IOP and prevent it’s during laryngoscopy and tracheal intubation. 100 patients were selected randomly and received either Midazolam 0.2 mg/kg, Sufentanil 0.2 microgram/kg, Atracurium 0.5 mg/kg (Group 1) or Propofol 2.5 mg/kg, Sufentanil 0.2 microgram/kg, Atracurium 0.5 mg/kg (Group 2). The IOP was measured before and after induction and immediately after intubation. Both groups showed a meaningful decrease in IOP following induction of anesthesia (P?0.0001). Laryngoscopy and intubation, increased IOP in group 1, however not significantly and still lower than the base line IOP (P=0.09). Group 2 showed no such increase (P<0.0001). We concluded that Propofol in comparison to Midazolam is more effective in prevention of IOP rise in response to laryngoscopy and tracheal intubation.

Background and Objective: Physical exercise and nutrition supplements are recommended interventions to reduce cachexia. This study was conducted to determine the effect of resistance training and resveratrol supplementation on muscle regeneration indices of MyoD (myoblast determination protein) and eMHC (embryonic Myosin Heavy Chain) in CT-26 colon cancer mice.
Methods: This experimental study was performed on 20 six-week-old BALB/c mice to which CT-26 tumor was implanted. The mice were divided into four groups of resistance training, resveratrol, combination of resveratrol with resistance training, and control. The resistance training group performed six weeks of progressive resistance training. The resveratrol group received 100 mg/kg resveratrol per day, and the control and resistance training group received the solution of Methyl cellulose through gavage. In gastrocnemius muscle MyoD protein and eMHC level were measured using western blot and ELISA methods, respectively.
Results: eMHC protein in combination of resveratrol with exercise group (4.66±0.25) increased significantly compared to the exercise group (3.46±0.64) (P<0.05). Body weight of mice without tumor (21.50±1.30) in the resistance training group increased significantly compared to other groups (P<0.05). There was no significant difference in the tumor weight of mice and MyoD protein in expermental groups.
Conclusion: Regarding the increasing effect of combination of resveratrol with exercise group compared to resistance training group on eMHC, resveratrol supplementation at higher doses may be recommended along with resistance training to improve muscle regeneration.
