To give basis to my disagreement with lightNlife, I'd like to point out that Pulmozyme does not follow the description of an antibiotic which "naturally" restores the body back to it's "occuring state of function"-(lightNlife quote).
In fact, by looking at the home page, and perhaps even finding it was indicated in one of my posts many months (or weeks) ago, the drug "Manipulates DNA" in order to get results.
So, anyone using that medication is getting their "DNA" rearranged.
True, the method to IVF is equally manipulative to the body, but then, what about those "Genetic Counselors"?
Also, the IVF is not cloning. Your example with the broken toaster sounds more like cloning. The IVF method is more like a stereo amp!!
You want to listen to the bass on one of Paul McCartney and Wing's albums, but your stereo doesn't have enough "clarity", so you turn it up until you can hear the bass! In the meantime, the neighboors are complaining that the stereo is too loud.
Moreover, With my understanding of IVF, you've got the eggs, and the guy's sample (not sure if it's okay to use the right word on this site) to make your 'milkshake' with!
And, to stay focused on the 'control' of CF, Until there is a cure for the 'source' of the problem, like ridding the double delta F508, then there won't be any way to 'kick it off this planet', so to say. One point to mention is that IF the gene can be riddened of, that also is due to the advancement in medical technology.
Hope I made my opinion clear without confusing anyone (I <u><b>almost</b></u> confused myself with it!)
Peace!
