[Patients with primary anterior uveitis. Determination of circulating immune complexes].

The level of circulating immune complexes (CIC) in 31 patients with primary anterior uveitis was determined by an ELISA method (C1q in solid phase). In addition, we measured antinuclear antibodies (ANA), HLAB 27, C3 and C4. Increased levels of CIC were found in 38% of patients (Group I), the remainder had normal levels (Group II).

New H-2-linked cell and serum antigens.

A system of two public serum antigens, alpha and delta, whose distribution in inbred strains of mice is different from that of all serum antigens known, is described. Their distribution in the H-2 congenic and in the recombinant inbred HTG strain indicates that they are determined by a gene(s) tightly linked to H-2. Backcross tests confirmed this; only 1.
