The Turkish Journal of Hematology accepts invited review articles, research articles, brief reports, case reports, letters to the editor, and images in Hematol-ogy on subjects within the scope of hematology, on the condition that they have not been previously pub-lished elsewhere. All papers are subject to editorial revision for purpose of conformity to the style adopt-ed by the Journal. Manuscripts should in general not exceed 20 typewritten pages for original articles or reviews and 7 typewritten pages for case reports, in-cluding all tables, fi gures and illustrations.

Preparation of Manuscript

Title Page should include (in Turkish when possible): (a) title of the ar-ticle in a concise but informative style, (b) fi rst name, middle initial, last name of each author, (c) name of department(s) and institution(s) to which the work should be attributed, (d) name and address of author responsible for correspondence for the manuscript, (e) name and address of author to whom requests for reprints should be addressed, (f) source(s) of support in the form of grants, equipments, drugs, etc., and (h) short running title of no more than 40 characters.

Authorship: Each author should have participated suf-fi ciently in the work to take public responsibility for the content. Any part of an article critical to its main conclu-sions must be the responsibility of at least one author.

Abstract and Key Words: The second page should in-clude an Abstract which does not exceed 2500 char-acters. For manuscripts sent from Turkey, a title and abstract in Turkish are required. The abstract should state the purpose of the study or investigation, basic procedures, methods, main fi ndings, specifi c data, statistical signifi cance and the principal conclusions. Provide 3 to 5 key words below the abstract to as-sist indexers. Use terms from the Medical Subject Headings List of Index Medicus (www.nlm.nih.gov/mesh/MBrowser.html)

The text should be divided into sections with head-

ings as follows: Introduction, Materials and Methods, Results and Discussion. Other types of articles such as case reports, reviews, perspectives and editorials will be published according to uniform requirements.

Introduction: State the purpose of the article and sum-marize the rationale for the study.

Materials and Methods: Describe your selection of the observational or experimental subjects clear-ly. Identify the methods and procedures in suffi -cient detail to allow other workers to reproduce the results. Give references to established methods (in-cluding statistical methods), provide references and brief modifi ed methods, give reasons for using them and evaluate their limitations. Identify all drugs and chemicals used, including generic name(s), dose(s) and route(s) of administration. Statistics: Describe statistical methods in enough detail to enable a knowledgeable reader with access to the original data to verify the reported results. Give details about randomization, describe treatment complica-tions, give number of observations, and specify any computer program used. Ethics: When reporting ex-periments on human subjects indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation. Do not use patient names, initials, or hospital numbers, especially in any illus-trative material.

Results: Present your results in logical sequence in the text, tables and illustrations. Do not repeat in the text all the data in the tables or illustrations; emphasize or summarize only important observations.

Discussion: Emphasize the new and important as-pects of the study and the conclusions that follow them. Link the conclusions with the goals of the study but avoid unqualifi ed statements and conclusions not completely supported by your data.

Acknowledgements: On a separate page after the completion of the Discussion section, one or more statements should mention, if necessary, (a) contribu-tions that require acknowledgement but do not jus-tify authorship, (b) any technical help, and (c) fi nan-cial and material support, specifying the nature of the support.

References: Identify references in text, tables and leg-ends by Arabic numerals in parentheses. Number ref-erences consecutively in the order in which they are fi rst mentioned in the text. The titles of the journals should be abbreviated according to the style used in
