Moreover, a glyoxalase I-specific antiserum revealed many intensely stained flame-shaped neurons in Alzheimer's disease brain compared with brains from nondemented controls.
We determined the gene frequencies for the alleles of the HLA-linked complement markers C2, properdin factor B (BF), C4A (Rodgers) and C4B (Chido), and the red cell enzyme glyoxalase-I in 38 unrelated patients with senile dementia of the Alzheimer type, 42 patients with idiopathic Parkinson's disease, and 59 unaffected, aged-matched control blood donors.
