Assessment of oral acetazolamide on postoperative pain after laparoscopic cholecystectomy
Background and aim: Carbon dioxide (Co2) is used during laparoscopy for producing pneumoperttoneum. Combination of this gas with irrigation fluid in the abdomen produces carbonic acid which creates two kinds of abdominal and referred pain to right shoulder. In the present research we have studied the effect of oral acetazolamide in reducing postoperative pain after laparoscopic cholecystectomy. Methods: This clinical trial was performed in 88 patients with cholelithiasis without any complication that were candidate for laparoscopic cholecystectomy. The patients devided randomly and equally in two groups. The experimental group received Acetazolamide (250mg orally 24 hours before surgery every 8 hours) and control group received placebo. Abdominal and shoulder pain measured using Mc Gill pain score by a person who was blind for both groups. Pain measurement was performed in four different times before and after the surgery discharge from recovery and 24 hours after surgery. Data were analyzed by using SPSS software. Results: We observed that mean pain scores was significantly higher in acetazolamide group compared to the placebo group 24 hours after the operation (P0.05). Conclusion: Although acetazolamide can reduce abdominal pain referred to right shoulder by reducing acidity in peritoneal irrigation fluid but this drug can increase abdominal pain in the site of surgery with damaged tissues by producing tissue acidosis (as a side effect of drug)
The effect of corrective exercises on balance in elderly women with hyperkyphosis
Background: Women with hyperkyphosis have impaired balance and increased body sway, which can increase their risk of falls. Impaired balance and poor postural stability are the main risk factors for falling. This study aimed to study the effect of corrective exercises on balance in elderly women with hyperkyphosis. Methods and Materials: In this quasi experimental study, 30 adult women (age range, 60-75 years old) were selected using a purposive sampling and assigned randomly into the experimental and control groups. Participants in the experimental group took part in an 8-week (3 sessions a week) corrective exercise program. In this period, the control group did not receive any corrective exercise program. The flexicurve ruler and Berg balance scale were used in pre- and post-tests to measure kyphosis angle and balance, respectively. This study was conducted in Spring 2014 at Jahandideh Nursing Home in Arak city, Iran. The number of falls and fears of falling was also recorded. To analyze data, dependent t-test and covariate analysis at a significance level of
A review of relations for physical properties of nanofluids
Abstract: So far a lot of researchers have attempted to find a suitable relation to predict physical properties of nanofluids. But most of traditional formulae which belong to big size particles were not useful for nanofluids and empirical correlations also have their working condition limitations. There are several factors such as particle shape, size and material, interaction between particles, temperature, velocity, type of fluid flow, physical properties of both particle and base fluid and which affect on determination of physical properties of nano fluids. In this paper has been reviewed and classified all existing formulae and correlations about physical properties of nanofluids including thermal conductivity, viscosity, density and specific heat
Effect of ten-week aerobic training with flax seed supplementation on blood lipids profile and C-reactive protein in obese women
Background and Objective: Flax seed has been shown to play a role in the prevention and treatment of dislipidemia and inflammation, which may enhance the benefits of training. This study was done to determine the effect of 10 weeks of aerobic training with flax seed supplementation on blood lipids profile and C-reactive protein in obese women.
Methods: In this clinical trail study, 45 obese middle-age women were randomly divided into 3 groups. Aerobic training program was performed 50-60 min/d, 3d/wk, for 10 weeks. Subjects in aerobic training with flax seed supplementation were received 6-9 garms, daily of flax seed. Body composition and metabolic parameters were assessed before and after the training period.
Results: Flax seed supplementation significantly improved triglyceride, HDL-cholesterol TC/HDL, body weight, body mass index, waist circumference and fat mass (P<0.05). Flax seed supplementation in combination with aerobic training significantly improved adiposity indices body weight,body mass index, waist circumference , fat mass, triglyceride, HDL- cholesterol, LDL- cholesterol, LDL/HDL and TC/HDL (P<0.05).
Conclusion: Flax seed is safe and effective for improvement of cardiometabolic health in obse women and combination of flax seed can enhance beneficial effect of training over a ten-week period
