This is very true. I did a bunch of reasearch on PPH(this lung disease) in Jan . of 2003 and herd of this. The Dr's thought my mom had PPH. Thank goodness she doesn't. It's a horrible disease. There is also alternative homeopathic trils being done with L'Arginine(SP) its an herb that has very similar effects as viagra.
