For preparing the text, the current or previous version of Microsoft Word is recommended. Otherwise, the text may be submitted in the text file format. A covering letter should also accompany the manuscript. Figures should be prepared as a separate file.

(2) Abstract
Repeat names of the authors and the title of the manuscript at the top of the page. The body of the abstract should not exceed 200 words, and should be structured into the sub-sections “Objective,” “Methods,” “Results,” and “Conclusion(s).” Following the abstract, a maximum of five (5) keywords should be selected and indicated. For submission, the abstract should be submitted as its own file.

(3) Text
The main body of the manuscript should consist of “Introduction,” “Materials and Methods” or “Patients and Methods,” “Results,” “Discussion,” “Acknowledgments,” “References,” “Tables,” and “Figure Legends.”

1. Introduction
This section should position the study with regard to objective, rationale, and preceding works of other authors.

2. Materials and Methods
This section should contain a statement that “The investigation conforms with The Guide for the Care and Use of Laboratory Animals published by the U.S. National Institutes of Health (NIH Publication No. 85-23, revised 1996)” for studies involving experimental animals, or that “The investigation conforms with the principles outlined in the Declaration of Helsinki” (Cardiovascular Research 1997; 35: 2-4) when human subjects were used. The methods section should be sufficiently detailed for repetition of the study by other scientists.

3. Results
If pertinent, the section may be divided into headed sub-sections. For presentation of data, figures are preferred to tables. Also, extensive numerical data should appear in Figure Legends rather than in the main body of the text. SI units should be used.

4. Discussion
This section should not contain paragraphs dealing with topics that are beyond the scope of the study.

5. Acknowledgments
