[Sex hormones in the systemic and local circulation in endometrial hyperplasia and neoplasia: correlation with the activity of estrogen-metabolizing enzymes].

Sex hormone profile was investigated in uterine systemic and local blood flow in endometrial hyperplasia and carcinoma. The results were compared with levels of aromatase and steroid sulfatase - estrogen metabolism enzymes. Local hyperestradiolemia and hyperestronemia were detected in cancer patients.

[Listeria antigens and their isolated protein fractions].

Antigens have been obtained from standard Listeria strains 1 and 4a by alcohol precipitation, sonication and multiple freezing and thawing. From these antigens protein fractions, immunologically identical as shown by the precipitation test and immunoelectrophoresis and similar in their chemical composition, have been isolated. The immunogenic properties of the fractions are determined by the polysaccharide-protein complex represented by amino acids (proline, histidine, lysine) and monosaccharides (ribose, glucose, arabinose), common for the fractions of three antigens.
