INTRODUCTION

The introduction is concise, and states the reason and specific purpose of the study.

PATIENTS AND METHODS/MATERIAL AND METHODS

The selection of patients or experimental animals, in­cluding controls, should be described. Patients' names and hospital numbers are not used.

Methods should be described in sufficient detail to permit evaluation and duplication of the work by other investigators.

When reporting experiments on human subjects, it should be indicated whether the procedures followed were in accordance with ethical standards of the Committee on human experimentation (or Ethics Committee) of the insti­tution in which they were done and in accordance with the Helsinki Declaration. Hazardous procedures or chemicals, if used, should be described in details, including the sa­fety precautions observed. When appropriate, a statement should be included verifying that the care of laboratory ani­mals followed accepted standards.

Statistical methods used should be outlined.

RESULTS

DISCUSSION

An exhaustive review of literature is not necessary. The major findings should be discussed in relation to other pu­blished work. Attempts should be made to explain diffe­rences between the results of the present study and those of the others. The hypothesis and speculative statements should be clearly identified. The Discussion section should not be a restatement of results, and new results should not be introduced in the discussion.

ACKNOWLEDGMENTS

This section gives possibility to list all persons who contributed to the work or prepared the manuscript, but did not meet the criteria for authorship. Financial and ma­terial support, if existed, could be also emphasized in this section.

REFERENCES

References should be identified in the text by Arabic numerals in parentheses. They should be numbered con­secutively, as they appeared in the text. Personal communi­cations and unpublished observations should not be cited in the reference list, but may be mentioned in the text in parentheses. Abbreviations of journals should conform to those in Index Serbian Journal of Experimental and Clini­cal Research. The style and punctuation should conform to the Serbian Journal of Experimental and Clinical Research style requirements. The following are examples:

The authors are responsible for the exactness of reference data.

For other types of references, style and interpunction, the authors should refer to a recent issue of Serbian Jour­nal of Experimental and Clinical Research or contact the editorial staff.

Non-English citation should be preferably translated to English language adding at the end in the brackets native language source, e.g. (in Serbian). Citation in old lan­guage recognized in medicine (eg. Latin, Greek) should be left in their own. For internet sources add at the end in small brackets ULR address and date of access, eg. (Ac­cessed in Sep 2007 at www.medf.kg.ac.rs). If available, in­stead of ULR cite DOI code e.g. (doi: 10.1111/j.1442-2042 .2007.01834.x)

TABLES

Tables should be typed on separate sheets with table numbers (Arabic) and title above the table and explanatory notes, if any, below the table.

FIGURES AND FIGURE LEGENDS

All illustrations (photographs, graphs, diagrams) will be considered as figures, and numbered consecutively in Arabic numerals. The number of figures included should be the least required to convey the message of the paper, and no figure should duplicate the data presented in the tables or text. Figures should not have titles. Letters, nu­merals and symbols must be clear, in proportion to each other, and large enough to be readable when reduced for publication. Figures should be submitted as near to their printed size as possible. Figures are reproduced in one of the following width sizes: 8 cm, 12 cm or 17 cm, and with a maximal length of 20 cm. Legends for figures should be given on separate pages.

If magnification is significant (photo micrographs) it should be indicated by a calibration bar on the print, not by a magnification factor in the figure legend. The length of the bar should be indicated on the figure or in the figure legend.

Two complete sets of high quality unmounted glossy prints should be submitted in two separate envelopes, and shielded by an appropriate cardboard. The backs of sin­gle or grouped illustrations (plates) should bear the first authors last name, figure number, and an arrow indicating the top. This information should be penciled in lightly or placed on a typed self-adhesive label in order to prevent marking the front surface of the illustration.

Photographs of identifiable patients must be accompa­nied by written permission from the patient.

For figures published previously the original source should be acknowledged, and written permission from the copyright holder to reproduce it submitted.

Color prints are available by request at the authors expense.

LETTERS TO THE EDITOR

Both letters concerning and those not con cerning the articles that have been published in Serbian Journal of Experimental and Clinical Research will be conside­red for publication. They may contain one table or figu­re and up to five references.

PROOFS

All manuscripts will be carefully revised by the publisher desk editor. Only in case of extensive corrections will the manuscript be returned to the authors for final approval. In order to speed up publication no proof will be sent to the authors, but will be read by the editor and the desk editor.
