Transcript of Blue People of Kentucky A pedigree study. Troublesome Creek 6 generations ago after a French orphan...
Troublesome Creek
• 6 generations ago after a French orphan named Martin Fugate claimed a land grant in 1820 and settled on the banks of eastern Kentucky's Troublesome Creek,
He came with…
• his red-headed American bride, the former Elizabeth Smith, whose skin was as pale as the mountain laurel that blooms.
Married a lot of Kin
• Lived in the holler
• Did not get out much
• Might marry the girl next door, even is she had the same last name.
Figuring out the problem
• Dr. Madison Cawein was a hematologist at the University of Kentucky Medical Center when he heard stories about the blue people.
NADH Diaphorase Activity in Blue People
• Red blood cells (RBC) from blue people are deficient in NADH diaphorase activity and cannot reduce the oxidized iron in methemoglobin (metHb).
Dr. Cawein’s Treatment
• He injected Patrick and Rachel with methylene blue and within a few minutes, they both turned pink!
