Sergio Rodriguez Leal, Mexico. Nov. 11, 2007. I want to present my most heartfelt congratulations about your Web Site since I found the most complete information that someone in Toxicology want to share. In my country, unfortunately there is not a website with this capability and extensive knowledge for the purposes of education and guidance to the general public and so interactive, too. I congratulate you for your research, teaching and experience over the years who share with all. Today I learned more with you that what I have wanted for months in Mexican pages in my area of hospital emergency. Thank you, I’ll come back soon to visit it and to learn more of their diversity and to continue to serve better the people who need our attention. Editor’s note: we are grateful for this gratifying recognition.
