Abstract
In a 4-year-old male with Menkes kinky hair disease (MKHD) treated with copper supplement therapy, reduced cytochrome a + a3 contents in liver was demonstrated to be 0.029 against 0.128 nmol/mg protein in the control. Cytochrome c oxidase activities in brain, liver, skeletal muscle, and heart were 47, 22, 54 and 59% of the control, respectively. The copper contents in brain and liver were decreased. In spite of increased serum levels of copper and ceruloplasmin, the decreased cytochrome c oxidase activities in various organs were not corrected by copper supplement therapy. A search for a therapeutic method which can normalize copper enzymes in brain and liver, would seem to be a prerequisite for the treatment of MKHD.
