    and Abstract

    Provide 3-10 key words or phrases for indexing purposes, using terms from the latest US National Library of Medicine’s Medical Subject Headings (MeSH) browser list at (http://www. nlm.nih.gov/mesh/meshhome.html). If appropriate MeSH terms are not available, other suitable terms may be used. Full-length submissions should include an abstract of up to 250 words in structured form, consisting of an Objective, Methods, Results, and Conclusion.

    Text

    The text should include the following sections. The Introduction summarizes the rationale,provides a concise research background (not an exhaustive review) and states in one sentence the objective of the study. Do not include any results or the conclusions of the study. The Materials and Methods provide technical information about the study. Do not describe methodological details that have been published previously. Specifi cations (including the manufacturer, city,and the country) should be given for the main drugs, chemicals, and instruments. Indicate the statistical methods used and identify statistical signifi cance using superscripts (a and b)following the data (aP < 0.05,bP<0.01). The Results are the fi ndings, using SI units. In a sample,the number of effective digits is determined by the variation within the sample, that is, one-third of the standard deviation. Digits may be separated into groups of three by a small space. The Discussion deals with the interpretation of the results and their comparison with those of other studies. Do not repeat the results, do not review the literature, do not repeat textbook knowledge and do not cite references that do not have a close relationship with the present results. End with a brief conclusion linking back to the aim of the study.

    Abbreviations

    The use of abbreviations, except for units of measure, is discouraged. At the fi rst appearance in the abstract and the text, abbreviations should be preceded by words for which they stand.

    Tables

    Tables must be concise and cited consecutively using Arabic numerals in the text (Table Table 2, etc.). Each table should be typed on a separate sheet. The title of the table should clearl indicate the nature of the contents and suffi cient details should be included in the footnote t facilitate interpretation without reference to the text. Use horizontal rules only.

    Figures

    Figures (photographs, drawings, diagrams and charts) should be clear, easily legible and cite consecutively using Arabic numerals in the text (Figure 1, Figure 2, etc.). Please supply fi gure 1.5 to 2 times the size at which they will be fi nally reproduced. For line work, submit black ink drawings of professional quality. Micrographs or other glossy photographs must be of th highest quality. If a fi gure comprises more than one glossy photograph, these should be marke A, B, C, etc. Figure legends should be marked clearly with the correspond letter. Legends shoul contain suffi cient details to permit fi gure interpretation without reference to the text. Scal markers should be indicated in the photographs. Color plates are also welcome. The choice o cover art illustration will be made by the Editor.

    References

    The Journal advocates the citation of new papers; old references are better replaced with update ones. The authors are responsible for the correctness of references. References are numbere consecutively in the order in which they appear in the text. Citation should be labelled i superscript parenthesis and should appear in front of the period or comma at the end of th sentence/clause. All references should be cited.
