[Prophylactic effect of enteral feeding preparations during the chemotherapy of oncology patients].

Altogether 124 patients were followed up for disseminated breast cancer (82) and hematosarcoma (42). The patients were divided into two groups: the main group was given 500 ml of 20% protein or low-lactose enteral feeding in addition to the hospital diet; the control group received only the hospital diet. Chemotherapy lasted 3 weeks.

[Monolayer culture of bone marrow and splenic fibroblasts in lymphoproliferative diseases].

The authors describe the results of monolayer cultivation bone marrow and spleen fibroblasts in patients with lymphoproliferative diseases. The efficacy of colony-formation of fibroblasts (ECFf) was studied in 10 patients with chronic lympholeukemia, 4 with leukemic reticuloendotheliosis, in 5 with lymphocytoma of the spleen, and in 3 with lymphosarcoma of the spleen. The control group comprised 7 normal subjects.

[Conditions and characteristics of the early stages of the sexual interaction of Pichia amethionina var. amethionina and Pichia amethionina var. pachycereana yeast cells].

Pichia amethionina varieties have different sensitivity to the acidity of the medium: P. amethionina var. amethionina has the optimum pH 3 for agglutination and 5 for conjugation; P.

[Characteristics of nonspecific resistance in children with lung diseases due to opportunistic microflora].

Acute destructive pneumonia in children was found to be complicated by acute pleural empyema (APE) on days 3-21 of the disease. The time of the development of this complication depended on the state of the nonspecific resistance of the body: the greater was the degree of deficiency as manifested by cell-mediated and humoral immunity indices, the earlier developed APE. Staphylococci and Pseudomonas aeruginosa infected the pleural cavity of children under the conditions of essentially decreased phagocytic activity, phagocytic index, C'H50 and one of the classes of immunoglobulin.

[Possible use of DNA cytophotometry and karyometry for the cytological diagnosis of human prostate cancer].

Karyometric and cytophotometric parameters of the prostate epithelium are examined on the pattern of aspiration biopsy under benign hyperplasia and carcinoma of different grades of differentiation. The results obtained suggest that the distribution of the nuclei, according to their volume and DNA values, and the calculated index of DNA accumulation per cell may be used for differential diagnostics of the prostate cancer and for making the morphological type of tumor more precise.

[Status and developmental prospects of the medical proton channel in the synchrocyclotron in Gatchina].

The medical proton beam on the synchrocyclotron in Gatchina modernized in 1980, is characterized by a simplicity of the beam adjustment that amounts to standard operations, the time of adjustment reduced considerably. The optical scheme ensures a good reproducibility of all the beam parameters from session to session. A large "zone of convergence" makes it possible to select a necessary irradiation field size with the diameter from 3 to 10 mm.
