Abstract
Background: Aquatic ecosystems pollution with heavy metals, especially mercury, has always been a major concern for aquatic organisms health. Hence this study not only described an innovative method for analyzing organic mercury compound, but also evaluated total and organic mercury concentrations in great cormorant and compared them with world health standards.
Materials and Methods: In this cross-sectional study, 18 great cormorants were randomly captured in March, 2009. Total and organic mercury of muscle, kidney, and liver tissues were analyzed by an advanced mercury analyzer made in the United States (Model Leco, AMA 254), and statistical analysis was done by Mann-Whitney U, and Kolmogrove-Smirnov tests.
Results: Mean accumulated total mercury in liver, kidney, and muscle tissues were 5.67, 3.59, and 2.26 mg kg -1 w.w., respectively and organic mercury formed 82, 79, and 58 % of the total mercury.
Conclusion: The levels of accumulated mercury in all tissues of great cormorant were more than the established limits by WHO, FAO, and EPA. These results can be a serious warning for consumers of these birds, especially vulnerable people.

Abstract
Background and Aim: Considering the effect of coronary heart disease (CAD) on the health status, the present study aimed to investigate the effectiveness of Mindfulness-Based Stress Reduction on health status and disease symptoms of patients with CAD after CABG.
Materials and Methods: The research method was single subject. The statistical population of study included all patients with coronary artery disease in Tabriz city who referred to Shahid Madani Hospital in Tabriz during the second six months of the year 2016 for rehabilitation after surgery. The study sample consisted of four available CAD patients. Seattle's Angina Questionnaire (SAQ) and a researcher-designed scale for CAD symptoms were used as tools. Data were analyzed through recovery percentage, PND, SMD and visual analysis of chart method.
Ethical Considerations: This study with research ethics code 2384411 has been approved by research ethics committee at Tabriz university of medical sciences, Iran.
Findings: Results indicated that MBSR has a moderate efficiency in improving the disease symptoms. The effectiveness of MBSR is relatively low in improving the health status of patients with CAD.
Conclusion: It can be concluded that MBSR is a relatively effective treatment on reducing disease symptoms of CAD patients and is a relatively poor intervention to improve the health status of these patients.
