ABSTRACT Introduction & Objective: There are many noninvasive methods to measure systolic blood pressure. A new noninvasive method by pulse oximetery has recently been reported. The purpose of this study was the comparison of systolic blood pressure measurement by pulse oximetery and with auscultatory method. Material & Methods: Systolic blood pressure measurement using pulse oximeter was compared with current auscultatory method. Thirty one healthy volunteers enrolled and were positioned in supine, prone and lithotomy for three 10 minutes periods. Blood pressure was measured at the end of each position by two methods. Results: There was a significant correlation between two method in all positions supine (r= 0.72), prone (r= 0.88) and lithotomy (r= 0.78). Conclusion: Pulse oximeter seems to be a useful non-invasive method of systolic blood pressure measurement. In order to increase the accuracy of this method, low speed of cuff inflation and deflation is strongly recommended.

Background & Aim: High blood pressure in modern societies is considered a risk, so this study was carry out to investigate knowledge and practice of hypertensive patients based on national program to prevent and control the disease in Boyer Ahmad city. Methods: This study is a cross sectional descriptive study on 237 patients of high blood pressure had been applied. Subjects selected by stratified random sampling. Data collection instrument was a own structured questionnaire. Data entered in SPSS software version 11.5 and descriptive statistics and chi square test has been used for analyze of data. Results: The overall awareness and practice level of the patients equal to, 85% and 56%, respectively. Overall performance of patient 35.4 and 85.2 percent of patients taking the medicine as directed by your doctor respectively. 42.2 percent of patients had exercised are appropriate. 4.2 percent have managed to quit smoking. Relationship between literacy and general awareness of patients was significant (P=0.001). The difference between before and after g or identify patients was significant (P<0.001). Systolic blood pressure per year history of hypertension increases the amount of 1.26 mm Hg unit had increased.(P<0.001).Communicate knowledge and practices indicate that increased an awareness rating of .12 points increase in performance is observed.(P=0.001). Conclusion: Knowledge services to target populations considered consistent with national plans, but their performance in the field of medicine, diet, exercise and quit smoking program is not Compliant. A further study to improve the performance of patients is recommended.

Introduction: Glycyrrhiza glabra has been traditionally used as a medicinal plant in Iran. In this study to determine some of its mechanisms, the effects of hydro alcoholic extract of Glycyrrhiza glabra on electrocardiogram were examined by the following procedure: methods: Adult male rats were anesthetized via injection of pentobarbital sodium, then Femoral vein and femoral artery were canulated for injection and blood pressure recording respectively. Electrocardiogram was recorded by limb electrodes linked to A-D instrument power lab Bio amplifier also Blood pressure was recorded by pressure transducer linked to A-D instrument power lab.Tested groups were as follows: The first group, received Glycyrrhiza glabra extract (90mg/kg) and equivalent volume of the Glycyrrhiza glabra solvent (ethanol %70). the second group, received Glycyrrhiza glabra extract and acetylcholine (.01 mg/kg). Result: The result showed a significant decrease of RR interval and R amplitude in presence of licorice extract, licorice extract and acetyl choline with comparing to control condition also systolic and diastolic blood pressure showed a significant decreasing in presence of licorice extract with comparing to control condition. Conclusion: It can be concluded that Glycyrrhiza glabra has a positive chronotropic and negative ionotropic effects on heart via synergistic effect with cholinergic system
