Authors are requested to follow these instructions carefully. Manuscripts not prepared accordingly will not be accepted.

General

1. Journal of Nippon Medical School is the official journal of the Medical Association of Nippon Medical School and aims to introduce achievements in the fields of basic and clinical medicine. Articles contributed are classified into the following categories: originals, reviews, short communications, reports on experiments and clinical cases, and case reports. The articles must be written in English. Nonnative English language authors may contact the editorial office for English language assistance with their writings before submission on a fee basis.
   The articles must comply with the following rules concerning the Protection of Personal Information:
   1. No information that would facilitate the identification of a patient (name, initials, date of hospitalization, etc.) should be included;
   2. The general location where a disease broke out may be identified only if it is relevant to the patient's condition;
   3. The eyes should be blacked out in facial photographs of patients; if photographs of patients with eye diseases are used, the rest of the face should not be identifiable;
   4. Identifying information such as numbers should be removed from images and from biopsy and autopsy data.
2. Studies reported in contributions to Journal of Nippon Medical School must be based on humane experimental practices and observe the latest versions of The Declaration of Helsinki, Guide for the Care and Use of Laboratory Animals or the established guiding principles and standards in the relevant field of research.
3. Journal of Nippon Medical School is designed primarily as a platform for members of the Medical Association of Nippon Medical School to publicize their research. However, articles may be submitted by other researchers in Japan and around the world. The number of authors of individual articles except case reports should in principle be limited to ten; researchers submitting articles with more than ten authors should at the same time submit reasons to justify the number. For case reports, the number of authors is limited to no more than six.
4. Submitted manuscripts must be accompanied by a completed "Declaration of Copyright Transfer" (a copy is printed in each issue of the Journal, but copies are also available from the Editorial Committee on request).
5. Rules governing the length of papers, and the number of figures, tables and photographs are as follows. Originals are limited to a maximum of 8,000 words with the minimum number of figures, tables and photographs. Reviews, short communications, and reports on experiments and clinical cases are limited to 4,000, 1,200 and 1,600 words, respectively. In each case, the maximum number of words applies only to the main body of the text. Twelve pages are allowed for figures, tables and photographs in reviews, two pages for short communications, and six pages for reports on experiments and clinical cases. Case reports, including figures, tables and photographs, are limited to the equivalent of 3,000 words.
6. Except in the case of articles requested by the Editorial Committee, publication expenses are borne by the author. Authors will be notified of the exact sum.
7. If accepted for publication, articles should be submitted on an electronic storage medium (floppy disk, or CD-R [RW] ).

Tables
Tables with suitable titles and numbered with Arabic numerals should be placed at the end of the text on separate sheets (one table per page) . They should be understandable without referring the text. Column headings should be kept as brief as possible and indicate units.

Figures and legends
Figures and photographs should also be submitted on separate pages at the end of the article (new page for each figure). They should be numbered in order of appearance with Arabic numerals (for instance Fig. 1, Fig. 2/Photo 1, Photo 2). Photographs should be submitted in triplicate and should be high-contrast glossy prints. Polaroid photographs are not acceptable. Color photographs can only be printed at the cost of author(s).

Numbers, letters and symbols must be large enough to be legible after reduction. Each figure must have an accompanying legend, which should be understandable without reference to the text. All of these legends should be collected together on a separate page (typewritten in double spacing) rather than placed under the figures they refer to. Each figure's position in the text should be clearly indicated.
