The aim of this study was to evaluate complications of intravenous Streptokinase therapy in acute myocardial infarction patients admitted to the cardiac intensive care unit.

Myocardial infarction is a common disease and the use of thrombolytic agents such as Streptokinase reduces its mortality، but there are some complications associated with streptokinase.

In this descriptive stud y 120، patients treated with streptokinase were evaluated in terms of complications of the drug. A checklist of Streptokinase complications was used to collect the data. The findings were presented in the form of descriptive and inferential statistics.

According to the finding s، %33. 3 of patients had cardiovascular complications، %23. 9 developed allergic symptoms، and %17. 5 suffered blood complications.

The incidence of cardiac complications was the highest among patients. It is recommended to train nurses to avoid possible complications.

The aim of this study was to examine the effect of muscle relaxation and music therapy on anxiety level in patients waiting for cardiac catheterization.

Anxiety is one of the most common human emotions from positive or negative experiences of life. High levels of anxiety have many unwanted effects on the body systems. In stressful situations such as invasive diagnostic techniques، the person experiences high level of anxiety. One of the main responsibilities of nurses is to control anxiety in patients with pharmacological and non-pharmacological methods.

This quasi-experimental study was conducted in one hospital affiliated to Tehran University of Medical Science. After obtaining approval and written consent، 150 patients، waiting for cardiac catheterization، were randomly divided into three groups of muscle relaxation، music therapy and control. Data were collected by demographic form and self-report form of anxiety through interview. One hour before cardiac catheterization، the level of anxiety was measured in all groups، then، muscle relaxation group was asked to perform Benson muscle relaxation for 20 minutes based on listening to a recorded tape of guidance by headphone. At the same time، the music therapy group listened to music tape by headphone. Control group received no intervention but standard nursing care. Immediately before cardiac catheterization، the level of anxiety was measured again in all groups. Data were analyzed by SPSS using Fisher exact test، Mann-Whitney and Kruskal-Wallis tests.

Immediately before catheterization، patients'' anxiety level was significantly reduced (p<0. 001) in muscle relaxation and music therapy groups، while it increased in the control group. Immediately before catheterization، a statistical significant difference was found between levels of anxiety in groups (p<0. 001).

Both Benson muscle relaxation and music therapy significantly reduced anxiety level of patients and music therapy had more effect on the anxiety level of patients waiting for cardiac catheterization.

The purpose of this study was to determine the effect of -8week aerobic training on serum levels of high sensitivity C-reactive protein (hs-CRP) in high school male students with different Body Mass Indexes (BMI).

The low-grade chronic inflammation، which is characterized by increased levels of inflammatory markers in blood (such as CRP، Interleukin 6) is a strong risk factor for some chronic diseases. The hs-CRP is the most sensitive marker of inflammation and independent predicator of cardiovascular diseases and increase in hs-CRP levels are associated with obesity and cardiovascular diseases. The effect of aerobic training on hs-CRP of adolescents with different BMIs needs further investigation.

In this quasi-experimental study، 24 healthy and non-athlete boys (mean age، 16. 33 and standard deviation، 0. 47 years) were divided into three groups; «thin، normal، and overweight or obese» according to their BMI. The training program included -8week (three sessions per week) progressive aerobic running at intensities of %75-60 of maximal heart rate. To determine changes in hs-CRP levels، the blood samples were collected before and after training program in the identical conditions.

Training program had no significant effect on hs-CRP levels in all groups. There was a statistically significant difference in hs-CRP levels between obese group and the other two groups in esponse to training program، both before and after intervention.

Eight-week aerobic training did not have a significant effect on hs-CRP of the subjects، likely due to insufficient intensity and duration of exercise training and low baseline hs-CRP levels. Decreased hs-CRP levels in obese group، compared with other groups، was likely due to the obesity status and higher baseline hs-CRP levels.
