These mitochondria did not exhibit the regular double membrane wall structure, but showed a coalescence of these structures with a deliquescence of membranes thus exhibiting a complete disruption of normal ultrastructure. 3

It is interesting to note that therapeutic doses of intravenous ALA helps a liver regenerate but extremely high doses of the same agent causes liver necrosis. Does ALA help regenerate livers? Of course, excessive and unreasonable amounts of any 1 st large scale clinical trial with IV alpha ‐ lipoic acid at substance given intravenously can be lethal, including water NIH. and salt.

5/2/2016 We reported in 3 publications that we treated 79 people waiting for liver transplant surgery (acute hepatic necrosis) and 75 regenerated their livers with just the administration of intravenous Alpha ‐ lipoic acid. I was appointed by the FDA principal investigator for alpha lipoic acid as a prescription drug in 1983. That lasted 23 years.
