1) Camilla - I have come across references relating pd to carbon monoxide and if/when I see them again I'll let ya know. 2) While eating dinner tonight I had a couple thoughts I'd like to throw out for comment: - if PD is related possibly to a liver enzyme deficiency, whether genetic or induced by toxins, why is there not, and perhaps there is already, more research into understanding the health of one's liver vs trying to repair an already damaged brain? If the liver, not the brain itself, is the culprit, shouldn't there be more focus on that organ? In chinese medicine, PD and other sorts of trembling and even headaches, are all tied to the 'wind' energy. PD, particularly, is tied to an excess of liver 'wind'. In this system, the brain itself is not treated directly, but rather the organs which serve it are. i assume it depends on the specific brain problem being treated as to what organ(s) are to be involved. The idea is to strengthen one's liver (and perhaps kidneys too) and thus also its ability to filter out toxins, - Is it possible that chelation could remove toxins which the deficient liver is unable too? - What about fasting and other detox methods. Since, however, when fasting, the body turns to fatty tissue for energy due to a lack of incoming food, and supposedly toxins tend to be stored in fatty tissues, one must then be careful of these toxins being rereleased as the fatty tissue is absorbed. Fasting is used in many other cultures as part of a regular (weekly/monthly?) regimen. Has any research been done here as to any benefits? - What about liver transplants? Just a thought. Related to organ transplantation is the necessity thereafter of taking immunnosuppressive drugs to keep one from rejecting this 'foreign' organ. Has anyone considered use of these type of drugs in autoimmune diseases? (i.e., to keep one's own body from rejecting itself - perhaps a misguided and overzealous immune system or histological reaction?). Yeah, great dinner thoughts huh? But I thought I'd see what responses I could elicit. The question of the day is: How well do you know your liver? (Forget the brain for a while!) Wendy Tebay
