  == Oxidative stress and immune system ==  Thank you very much. My problem is exactly that I need a general approach to the topic, while the majority of papers I met on-line (including those found using the external links you seggested) is very specific. For this reason I was searching for a treatise. If you are so kind to seggest me a book about the immune systes that treat the subject, it will be great!  Many thanks.
