[Treatment of injuries of the menisci and ligaments of the knee joint].

Under observation were 288 patients with different internal injuries of the popliteal articulation. Isolated and associated injuries of the internal meniscus were found in 229 patients (79,5%). Operations were performed in 274 patients.

[Ellipsometric study of immunologic reactions on the surface of silicon].

Adsorption of human serum albumin (HSA), egg albumin (EA), immunoglobulin G (IgG) and immunologic reactions occurring between them on silicon surface were studied by ellipsometry. Adsorption of HSA, IgG and antibodies on the monolayer of antigen is monomolecular in their isoelectric points and can be depicted by Langmuir's equation. Adsorption of EA is polymolecular apparently because of great tendency of the protein to aggregation in aqueous solutions.
