摘要:

Frequencies of blood groups (ABO, MNSs, Lewis and Duffy), serum groups (Hp, Gc, Tf, C3 and Pi) and red cell enzyme types (PGM1, 6PGD, AK and ESD) were studied in 195 patients with allergic contact dermatitis caused by one or several allergens. The frequency of the blood group 0 was found to be significantly lower among patients with contact allergy, whereas the frequencies of the blood group Le (a–b–), the haptoglobin group Hp 1–1 and of rare Pi types (MS and MZ) were significantly increased. A significant deficiency of heterozygotes was found in the PGM1 system. In the Gc system the frequency of the Gc1 gene varied between patients with different numbers of alle

摘要:

A total of 73 sera obtained in two villages of the Krahó Indians of Brazil were tested for nine Ag factors. They were uniformly (x–y+), (a1–d+), (t+z–) and (h–) but showed polymorphism at the cg genetic site, the frequency of Agg being 0.63. Considering all the antigens together, the three arrangements found are not new, but their frequencies are different from those observed in one Caucasian, one Oriental and one African po
