1. Original Manuscripts
Manuscripts with original material will be considered for publication. Any part of the material, tables, or figures should not be published elsewhere. The journal does not recommend the submission of more than one article related to the same study. Original manuscript must be submitted in English will three copies of the manuscript and one set of figures. Manuscript must not be longer than 3,000 words.

Titles and authors name
The title should be concise with the authors’ name, including the first name and no more than two graduate degrees. Also to be included are: the name of the department and institution in which the work was done and address of the author.

Preparation of the Manuscript
Manuscripts should be typed, preferably on A4 paper (210 x 297 mm), single-sided and double-spaced. The top, bottom and side margins should be 25 mm. All pages should be numbered consecutively in the top right-hand corner, beginning with the title page.

Acceptance
The acceptance criteria for all papers are the quality and originality of the research and they are significant to the readership. Except where otherwise stated, manuscripts are peer reviewed by two anonymous reviewers and the Editors. The Editors reserve their rights to refuse any material for publication and advise that authors should retain copies of submitted manuscripts and correspondence as material cannot be returned. Final acceptance or refection rests with the Editors.

Style
Manuscripts should follow the style of the Vancouver agreement detailed in the “Uniform Requirements for Manuscripts Submitted to Biomedical Journals”, as presented at http://www.ICMJE.org/
Abbreviations should be used sparingly and only where they ease the reader’s task by reducing repetition of long, technical terms. Initially use the word in full, followed by the abbreviation in parentheses. Thereafter, use the abbreviation.
Drugs should be referred to by their generic names, rather than brand names.

Parts of the Manuscript
Manuscript should be presented in the following order:

• Title page
• Abstract (English and Thai) and keywords
• Text
• Acknowledgement(s)
• References
• Figure legend(s)
• Figure(s)
• Table(s) (each table complete with title and footnotes)

Footnotes to the text are not allowed and any such material should be incorporated into the text as parenthetical matter.

Title page
The title page should contain the following:

• Title of the paper,
• A short running head (no more than 50 characters, including spaces),
• Type of manuscript (e.g. Original Article, Short Communication, Review Article),
• Full names of the authors,
• Addresses of the institutions at which the work was carried out,
• Full postal and e-mail address, plus facsimile and telephone numbers, of the author to whom correspondence about the manuscript, proofs and requests for offprint should be sent.
• The present address of any author, if different from that where the work was carried out, should be supplied in a footnote.
• Conflict of interest statement

The title should be short (less than 80 characters, including spaces), informative and contain major keywords.
Listed authors should only include those individuals who have made a significant creative contribution to the manuscript: a list of more than six authors should be justified to the editors.

Abstract (English) and keywords
All Original Articles must have a structured abstract than states in 250 words or fewer detailing the purpose basic procedures, main findings and principal conclusions of the study. Authors are free to choose the most appropriate structure for the abstract but it will usually include the following headings: Objective, Methods, Results and Conclusion.
Short Communications and Review Articles should have an unstructured abstract of 150 words or fewer. The abstract should not contain abbreviations or references.
Five keywords (for the purposes of indexing) should be supplied below the abstract, in alphabetical order, and should be taken from those recommended by the US National Library of Medicine’s Medical Subject Headings (MeSH) browser list at www.nlm.nih.gov/mesh/meshhome.html.

Text
Authors should use subheadings to divide the sections of their manuscript: Introduction, Methods, Results, Discussion, Acknowledgements, and References.

• Introduction
  This should give a short, clear account of the background and reasons for undertaking the study. It should not be a review of the literature.
  
  
• Methods
  The methods must be described in sufficient detail to allow the experiments/data collection to be repeated by others. Common, routine methods need only be described in outline with an appropriate reference to a full description. Manufacturers of equipments and sources of chemicals and drugs must be identified. Calculations and the statistical methods employed must be described in this section. Experiments involving animals or humans must conform to normal ethical standards, and approval by an appropriate ethics committee should be stated, if applicable.
  
  
• Results
  The description of results should not simply repeat the data that appear in tables and figures and, likewise, the same data should not be displayed in both tables and figures. The results section should be concise and follow a logical sequence. Do not discuss the results or draw any conclusions in this section.
  
  
• Discussion
  Discuss the significance of the results against the background of existing knowledge, and identify clearly those aspects that are novel. The final paragraph should highlight the main conclusion(s), and provide some indication of the direction future research should take.
  
  
• Acknowledgement(s)
  The source of financial grants and other funding should be acknowledged, including a frank declaration of the author’s industrial links and affiliations. The contribution of colleagues or institutions should also be acknowledged. Thanks to anonymous reviewers are not allowed.
  
  
• References
  The Vancouver system of referencing should be used. References should be cited numerically in the order they appear in the text. Identify references in text, tables and legends by Arabic numerals in parentheses or as superscripts. Please give names of all authors and editors. In the reference list, the references should be numbered and listed in order of appearance in the text.

Cite the names of all authors when there are six or fewer; when there are seven or more, list the first three followed by “et al”.
Names of journals should be abbreviated in the style used in Index Medicus (see examples below).
Reference to unpublished data and personal communications should not appear in the list but should be cited in the text only (e.g. A Smith, unpubl. Data, 2000).

Figure legends
Legends should be self-explanatory and typed on a separate page titled “Figure Legends”. The legend should incorporate definitions of any symbols used and all abbreviations and units of measurement should be explained so that the figure and its legend are understandable without reference to the text.
If a table or figure has been published before, the authors must obtain written permission to reproduce the material in both print and electronic formats from the copyright owner and submit it with the manuscript. This also follows for quotes, illustrations and other materials taken from previously published works not in the public domain. The original source should be cited in the figure caption or table footnote.

Tables
Tables should be self-contained and complement, but without duplication, information contained in the text. Tables should be numbered consecutively in Arabic numerals (Table 1, Table 2, etc). Each table should be presented on a separate page with a comprehensive but concise legend above the table. Tables should be double-spaced and vertical lines should not be used to separate the columns. Column headings should be brief, with units of measurement in parentheses; all abbreviations should be defined in footnotes. The table and its legend/footnotes should be understandable without reference to the text. Authors should ensure that the data in the tables are consistent with those cited in the relevant places in the text, totals add up correctly, and percentages have been calculated correctly.

Figures
All illustrations (line drawings and photographs) are classified as figures. Figures should be cited in consecutive order in the text and should be submitted electronically along with the manuscript. Figures should be referred to specifically in the text of the paper but should not be embedded within the text. The use of three-dimensional histograms is strongly discouraged when the addition of the third dimensional gives no extra information.

2. Case Report
They will be accepted only if they deal with a clinical problem of sufficient interest. The text should not exceed 1,500 words; number of Tables, Figures, or both not more than two; and references not more than 15.
