[The levels of circulating immune complexes and immunoglobulins in patients with systemic lupus erythematosus and rheumatoid arthritis].

Unlabelled: The authors studied the levels of large- and medium molecular circulating immune complexes (CIC) and immunoglobulins of main classes (Ig) in 17 patients with systemic lupus erythematosus (SLE) and 47 patients with rheumatoid arthritis (RA).

Results: low molecular CIC increased in 35.2% of patients with SLE and in 42.

[Isolation and characteristics of fragments from the cyanogen bromide splitting of inclusion body proteins of Bombyx mori nuclear polyhedrosis virus].

The cyanogen bromide cleavage of "acetic" polyhedral protein from nuclear polyhedrosis virus of B. mori was performed. Two peptides BrCN-II and BrCN-II' which consist of 29 and 34 amino acid residue were isolated from a mixture of cyanogen bromide fragments.
