effect of progressive muscle relaxation program [PMR] on anxiety of patients undergoing coronary heart angiography

Coronary heart disease is major cause of death in the world. One of the diagnostic tests for coronary patients is catheterization which leads to stress and anxiety in most patients. Progressive muscle relaxation program [PMR] is no drug interventions to reduce anxiety in patients. The main purpose of this study was to evaluate the effect of PMR on anxiety of patients undergoing for coronary artery angiography. This pre-post semi-experimental research was performed on 146 patients referred to the Shahid Rajaei heart hospital in Tehran for angiography. Progressive muscle relaxation program was prepared on a CD and was delivered to the patients. The anxiety was evaluated using a questionnaire before and after starting the program. Data were analyzed by using statistical tests, such as Chi-square and paired-t tests. No significant statistical relation was seen between age, marital status and history of disease with anxiety agents [P>0.05]. Demographic characteristics of patients showed a significant statistical relation between educational status, economic status and occupational status and history of admission to hospital with anxiety agents [P<0.05]. Paired-T test showed a significant relation between anxiety in coronary heart patients before and after starting PMR program [P<0.05]. Results of this study demonstrate a positive effect of PMR study on reducing anxiety in patients undergoing coronary heart angiography. Because of this positive effect of PMR, using this method is recommended to control anxiety in similar patients

[Effect of Heracleum persicum extract on acid and pepsin secretion level in both basic and stimulated conditions with pentagastrin in rat]

The Heraclleum persicum is widely used as an odorant in pickles around the world and particularly in Iran. As pickle is a gastric stimulator, the question is whether this plant which is used in making pickles, decreases gastric stimulation of this group of foods, or increases it, and in general, what is the cellular mechanism of this plant on acid and pepsin secretion. Therefore, in this study the effect of plant entrants on the secretion rate of acid and pepsin surveyed in the stomach in rats. This study involves two groups [12 in each group] of rats in experimental method [Control group and Heracleum group]. After anesthesia with nesdonal, 50 mg/kg IP, rats were gone under surgical process, tracheotomy, laparatomy and gasteroadeodenostomy and the Heraclleum extract [12.5 mg/kg] was send into the stomach from gasterodeodenostomy canula in Herculean group. The amount of both acid and pepsin in both basal and stimulated condition were significantly increased in heracleum group compared to control group [p<0.001]. Pentagastrin also increased acid and pepsin secretion in control group [p<0.001] and increased pepsin in heraclleum group [p<0.05] but did not significantly change in acid secretion in heraclleum group. The Heracleum persicum increases acid and pepsin secretion when is used in food regimen. Its extract also increases gastric acid secretion via blockage of gastric receptor. However, a different mechanism is involved in the increasing of pepsin secretion

[Efficay of consoling guidelines on decreasing of psychological problems of newly arrived students of Shahrekord university of medical sciences]

Stress provokes unspecial responses and render necessary changes in life. Universities have many stressful conditions for newly arrived students such as being away from home, economical and communicational problems, etc. This study was performed to find the efficacy of consoling guidelines to decrease psychological problems in newly arrived students of Shahrekord university of medical sciences. The sample consisted of 40 persons out of 148 newly arrived students with a GHQ-28 questionnaire score of equal or more than 23. The sample was randomly divided into two groups of case and control. After 3 months [without any intervention] and 7 months [education of consoling guidelines] the psychological health was assessed by GHQ-28 questionnaire. The data was analyzed by ANOVA, t-test and Dunkan test. There was no significant relation between elapsed time, adaptation with university or being far away from family and psychological problems. But there was a significant correlation between education of life skills, relaxation or psychoanalysis and reduction of psychological problems. There was no reduction of disorders scale in the control group but there was a reduction in summarization scale, anxiety and social dysfunction in the case group. Consoling guidelines and psychological intervention such as education of life skills, psychoanalysis and relaxation could improve the life quality and reduce psychological problems of the students
