Manuscripts should be sent to The Associate Editor at the Faculty of Medicine for Girls, Al- Azhar University, or to P.O. Box 311 Orman, Giza, Cairo.The order of appearance of material in all manuscripts should be as follows: Title page, abstract, text, references, tables, legends for figures. The manner of presentation should suit the nature of material. Prospective authors should examine a recent issue of The Egyptian Journal of Immunology for example of the type of article to be submitted.

Title page: Each manuscript should have a title page that includes a title of not more than two printed lines (160 letters and spaces); the names and affiliations of the authors; a running head of not more than 45 letters and spaces; and footnotes indicating sources of financial support, changes of address, and the name and address of the person to whom requests for reprints should be sent. Acknowledgments of persons who assisted the authors should be included on the page preceding the references.

Abstract: The second page must contain an abstract of not more than 150 words. The abstract for a review or historical article should be a summary of the salient data, ideas, and conclusions presented in the text. The abstract for a research report should indicate the purpose of the research, the methods used, the results (with specific data given, if possible), and the conclusions. No references should be cited in the abstract. For lengthy review articjes, a table of contents may be supplied by the author or its addition suggested by the editors.

Introducion: The introduction should supply sufficient background information to allow the reader to understand and evluate the results of the present study without referring to previous publications on the topic. The introduction should also provide the rationale for the present study. Choose references carefully to provide the most salient background rather than and exhaustive review of the topic.

Materials and Methods: The Materials and Methods section must include sufficient technical information to allow the experiments to be repeated. The sources of all media and reagents (i.e., name and location of manufacturer) must be provided.

Results: Present the Results as concisely as possible in one of the following: text, table(s) or figure(s), Avoid extensive use of graphs to present data which might be more concisely presented in the text or tables. All tabular data must be accompanied by either standard deviation values or standard error of the means.

The statistical procedure used should be stated in Materials and Methods. Limit illustrations (particularly photomicrographs and electron micrographs) to those that are absolutely necessary to show the experimental findings.

Discussion: The discussion section should provide an evaluation Of the results in relation to previously published work. Avoid extensive repetition of the Results section or reiteration of the introduction.

References: The author is responisibIe for ensuring that the information in the reference list is accurate. References must be typed double-spaced. Only works that have been published or accepted for publication should be listed as references. Unpublished observations by the authors and personal communications should appear as parenthetical expressions in the text. References are numbered in alphabetical order.

References must follow the format of the National Library of Medicine as used in Index Medicine and "Uniform Requirements for Manuscripts Submitted to Biomedical Journals" (Ann Inter Med 1982; 96: 766-70). Provide all authors' or editors' names except when they number seven or more, in which case list the first three names and add et al. Titles of journals not listed in the curi Inidex Medicus should be spelled out in full. Reference to a doctoral dissertation should include author, title, institution, location, year, and publication information, if published. Examples of formats used are given below:

1. Kryger P, Pedersen NS, Mathiesen L, Nielsen JO. Increased risk of infection with hepatitis A and B viruses in men with a history of syphilis: relation to sexual contacts. J Infect Dis 1982; 145:23-6.

3. Anderson LJ, Wuikier WG, Baer GM. The Centers for Disease Coutrol's experience with a human rabies vaccine [abstract no. 475]. In: Program and abstract of the 19th Intersience Conference on Antimicrobial Agents and Chemotherapy. Washington, DC: American Society for Microbiology, 1979:109.

Footnotes: Substantive footnotes (containing a comment, explanation, or other than textual matter) are not used.

Statistical analysis: The tests used in statistical analysis should be identified both in the text and in any tables and figures where the results of statistical comparisons are shown.

Tables and figures: The same data should not be shown in both a table and a figure except in unusual circumstances.

Tables are numbered in the order of appearance in the text. Vertical rules are not used. Footnotes should be placed below the table and should be designated by the following symbols (listed in order of location when the table is read horizontally): *, §, ¦, #, etc. Each column must have an appropriate heading, and units of measure must be clearly indicated.

Figures, including line drawings and graphs, should be submitted as glossy prints, preferably no larger than 5 x 7 inches. Every print should be clearly labeled with the first author's name and figure number. Legends should be typed doublespaced on a separate sheet of paper.

Reproduction color figures is expensive; they can be published only if special arrangements are made with the editors. Photomicrographs should sbow only the most pertinent area of the material being studied or should be marked for cropping to avoid unnecessary reduction in size. A micron bar or appropriate scale marking must be placed on the figure.

Use ofAbbreviations: The use of abbreviations should be minimal; for example, terms such as reticuloendothelial system or Epstein-Barr virus should be spelled out in any article in which they appear only a few times. However, when such terms are repeated many times in an article, abbreviations (RES or EBV) may be introduced when the terms are first used and abbreviations used thereafter. Conventional or SI units of measure may be used without definition.

Language: Authors unsure of proper English usage should have their manuscripts checked by someone proficient in the English language. Manuscripts may be rejected on the basis of poor English or lack of conformity to accepted standards of style. EAI strongly recommends that for clarity you use the past tense to narrate particular events in the past, including the procedures, observations, and data of the study that you are reporting. Use the present tense for your own general conclusions, the conclusions of previous researchers, and generally accepted facts.
