Speculative discussion is not discouraged, but the speculation should be based on the data presented and identified as such. The Discussion should be as concise as possible, within the limits of ideas the authors wish to propose and adequate discussion of related work by others. For Short Communications, the Discussion may be incorporated into Results, heading as Results and Discussion. Grant support, if any, should be listed in this section. When essential, they are numbered consecutively and typed at the foot of the appropriate page.
Tables require a heading and the figures a legend.
The Legends should be prepared on a separate sheet. Abbreviations in the legends should conform to those in the text. Due to technical reasons, figures with a screen background should not be submitted. On the back of each illustration, indicate its number, the author s name, and 'top' with a soft pencil. Ballpoint pen should not be used.
