RESUMO
Background: Today, the relationship between asthma and obesity in many studies is reviewed and weight control is used as a way for control of symptoms and severity of asthma along with other treatment protocol. Portulaca oleracea is consumed for weight loss in some countries
Objective: The experiment is designed to study the effect of Portulaca oleracea seeds on anthropometric measurements in asthmatic patients
Methods: In a randomized clinical trial, 59 patients with asthma disease divided to intervention [n=31] and control [n=28] groups. First group received asthma treatment and consisting 10g/day P. oleracea seeds in two doses in the morning [fasting] and before dinner with a glass of water for 8 weeks. Participants in second group received only asthma treatment. At the beginning and end of the study, anthropometric measurements were measured on each subject
Results: The anthropometric measurements including weight, body mass index and waist circumference indicated any significant differences between two groups after completion of the study [P?0.05] but hip circumference and waist-to-hip ratio had significant decrease [P= 0.003] and increase in intervention group [P= 0.04], respectively
Conclusion: Consumption of Portulaca oleracea seeds influence on some anthropometric measurements likes hip circumference and waist-to-hip ratio in asthmatic patients. However, the effects of them on other anthropometric measurements need further investigations.Keywords: Anthropometric Measurements, Asthma, Obesity, Portulaca oleracea seed
RESUMO
Following thoracic and abdominal surgery, all patients experience a decrease in pulmonary volumes and atelectasis. Different methods such as lung physiotherapy, intermittent positive pressure breathing, positive expiratory pressure and incentive spirometry are suggested for improvement of pulmonary volumes and blood gas parameters in these patients. Due to cheap, simple and easy use of incentive spirometry, we aimed at evaluating the effects of it on pulmonary volumes and blood gases parameters [ABG] in coronary artery bypass patients. This is a randomized, clinical trial study. From February 2004 to February 2005, 150 consecutive male patients who were hospitalized for coronary artery bypass surgery in Madani heart hospital were divided into two groups at random. On the first day of operation, group I used incentive spirometry and group II was routinely followed up. Data were collected through a questionnaire including age, left ventricular function [LVEF], smoking and number of grafts. Blood gases parameters and spirornetry volumes were measured in 3 phases before, in the morning of the first day of operation and after using incentive spirometry. Data were analyzed by SPSS software using paired or unpaired student's t-test. There were no significant differences between two groups as to the mean age, LVEF, number of grafts and duration of mechanical ventilation in ICU. Comparison of ABGs before anesthesia and on the first day of surgery showed a significant decrease in systemic O[2] saturation and arterial Po2 in all cases [p<0.001], but no significant differences were found between the second and third phases in both groups. Spirometry parameters showed a decrease of forced expiratory volume in the first second [FEV[1]] and forced vital capacity [FVC] after surgery in all patients [p<0.0001], but by using incentive spirometery, no significant changes in spirometeric pulmonary volumes occurred. Using incentive spirometery on the first day of operation has no significant impact on pulmonary volumes and blood gases parameters
