Family and population studies of SAHH and ADA polymorphisms. A possible pitfall in the ascertainment of SAHH electrophoretic phenotypes.

Typing of both SAHH and ADA red cell electrophoretic patterns was carried out among the members of about 80 families from Latium (Central Italy) and in a random sample of about 350 individuals from two Italian regions, Latium and Sardinia. 1. The SAHH1 enzyme product provided another interesting example of a change in the electrophoretic pattern brought about by the haemolysate ageing.

Electrophysiological (EEG, BAEP, VEP) study in patients with beta-thalassemia major.

Twenty-four patients affected by beta-thalassemia major were studied by means of combined EEG, VEP and BAEP recordings. All the subjects were treated with regular blood transfusions and chelating therapy (DFO). An elevated incidence of EEG abnormalities (70.
