Authors submitting a paper do so on the understanding that the work has not been published before, is not being considered for publication elsewhere and has been read and approved by all authors. The submission of the manuscript by the authors means that the authors automatically agree to assign exclusive copyright to Blackwell Munksgaard if and when the manuscript is accepted for publication. When the manuscript has been accepted the corresponding author will receive a copyright assignment form from editorial office to be returned signed on behalf of all co-authors.

The work shall not be published elsewhere in any language without the written consent of the publisher. The articles published in this journal are protected by copyright, which covers translation rights and the exclusive right to reproduce and distribute all of the articles printed in the journal.

Provide your manuscript on one newly formatted 3.5-inch floppy disk; 4 printed, double-spaced copies including figures and tables must accompany the disk. The paper manuscript and the file on the disk must be the same. Label the disk clearly with the journal name, author and title, file content, computer system (DOS, Windows or Macintosh), word processor (Word, WordPerfect etc.) and version used. Do not convert your manuscript to ASCII format. Include only the files corresponding to the manuscript. Full details of manuscript submission on disk will be sent following notification of acceptance of the manuscript. Illustrative material of fine morphology (histology or electron microscopy) accompanying each copy of the manuscript must be originals (not photocopies). The journal cannot be held responsible for loss of or damage to mailed manuscripts, or for statements made by contributors.

Style of writing
Use a succinct style of writing. State the objectives of the study clearly, but avoid lengthy introductions. Refrain from overwriting the Results section, e.g., by making extensive cross-tabulations or otherwise presenting too many details of subordinate interest; rather, concentrate on a few important findings. In the Discussion, do not repeat in detail data given in the Results section, but instead emphasize the new and important aspects of the study. State clearly the implications and conclusions of the study. Remember that the editorial processing of concisely written manuscripts will be much more rapid than that of lengthy, complicated articles that have to be sent back to the author for remodeling.

Manuscript arrangement
The paper should be submitted in English. Type the manuscript double spaced, with margins of at least 25 mm (1 inch). Each manuscript component should begin on a new page in the following sequence: title page; abstract and key words (3 to 5); text; acknowledgements; references; tables; each table, complete with title and footnotes, on a separate page; legends for illustration. Number pages consecutively, beginning with the title page. Type the page number in the upper right-hand corner of each page. Number the tables consecutively with Arabic numerals. For any further details, consult the "Uniform requirements for manuscripts submitted to biomedical journals", Ref. 2 below.

Abstract
This must be structured into the following blocks: Background/purpose, Methods, Results, Conclusion.

Illustrations
All figures should clarify the text and their number should be kept to a minimum. Details must be large enough to retain their clarity after reduction.

Illustrations should preferably fill single column width (81 mm) after reduction, although in exceptional cases 2/3 width (120 mm) or full page width (168 mm) will be accepted. Submit unmounted prints of each illustration, identifying them with a label on the back that indicates the number, author's name and "top". Line drawings should be professionally drafted and photographed; halftones should exhibit high contrast. A linear size scale should be incorporated into electron microscopic pictures. Color illustrations may be accepted free of charge to the author at the discretion of the editor. Otherwise the author must pay for the illustrations at a rate to be quoted by the publisher.If there is a colour artwork in your manuscript to be paid for when it is accepted for publication, Blackwell Publishing require you to complete and return a colour work agreement form before your paper can be published. This form can be downloaded as a PDF* from the internet. The web address for the form is:

http://www.blackwellpublishing.com/pdf/Sub3000_X_CoW.pdf

Submit original transparencies and two sets of color prints.

Abbreviations and symbols
Use only standard abbreviations. All units will be metric. Use no Roman numerals in the text. In decimals, a decimal point, and not a comma, will be used. Consult the CBE style manual: a guide for authors, editors and publishers in the biological sciences, 4th edn., Arlington, Virginia, 1978. Avoid abbreviations in the title. The full term for which an abbreviation stands should precede its first use in the text unless it is a standard unit of measurement. Units of measurement should be expressed in accordance with the SI and CIE recommendations (see Ref. 3, below). For photodermatologic terminology, consult recent issues of Photodermatology, Photoimmunology & Photomedicine.

References
Number references consecutively in the order in which they are first mentioned in the text. Identify references in text, tables and legends by Arabic numerals (in parentheses). List all authors cited, and only these, at the end of the paper. Journal titles should be abbreviated according to the style used in Index Medicus.
