  1. Sections
    The manuscript of a research articile should be divided into the following sections: Introduction, Objectives, Materials and Methods, Results, Discussion, Conclusion, Limitations, Recommedations, Acknowledgements, References and Appendix.

    Generally, the introduction should be concise and focused on the specific subject of the manuscript. The objectives section should state the general and specific objectives of the study. The results section should contain only findings borne by the study. The discussion attempts to explain the findings of the study based on current knowledge. It should not be a literature review.

    Whenever appropriate, the metric system, Systeme International (SI) units, and temperature in degree Celcius are used. Non-roprietary (generic) names should be used
    for medical substances, unless the use of a specific brand name is important. In the latter situation, the pharma- ceutical interest should be declared.

    When acronyms or abbreviations are used, the acronym enclosed in parenthesis should initially follow the entire phrase or group of words. Abbreviations should be spelled out no matter how common they are.
  2. References
    In the text, the reference should be cited using super-script Arabic numerals placed after the sentence and in the order of their appearance.

    Use the Vancouver style of referencing. Write all names of authors if they number 6 or less. If more than 6 names, cite the first 3 and use”et al” for the rest. Unpublished
    work should not be listed under references. The citation should appear in the text and enclosed in parenthesis
    (e.g. Cruz J dl, 2008, unpublished data).

    For abbreviating names of Journals, use the Index Medicus style or access the list at

  3. Tables and Figures
    Tables and figures are placed in the appendix. Do not embed tables and figures within the body of the manuscript. Group tables together and all figures together. There should be no more than six graphics, including tables, figures, photos and slides per manuscript.

    Create tables using the table creating and editing feature of your word processing software (eg, Word, WordPerfect). Do not use Excel or comparable spreadsheet programs.
    Cite tables consecutively in the text, and number them in that order. They should be self-explanatory and should supplement, rather than duplicate, the material in the text. The tables should have concise but comprehensive legend. Column headings should be short with units in parenthesis, or statistical headings well-defined. Footnote symbols should be used (see Word, Insert, References, Footnote) except for the asterisk* which should be reserved for P values (i.e. 0.03*).

    When presenting photograph of subjects or specimen, any identifying mark should be cropped, or an eye bar should be used to prevent the subject from being recognized. Use arrows to emphasize subtle pictures. When submitting electronic or scanned photographs, resolution must be atleast 300 dpi. Markings, such as arrows, that are used to direct the attention of readers must be embedded in the files.
  4. Acknowledgement
    The source of funding or grants should be acknowledged. As earlier stated, when brand names of drugs are used, the author should declare pharmaceutical interest, his industrial links and affiliations. Other contributing personnel or institutions should also be acknowledged. Acknowledgement of writing inspirations is not allowed.
