[Present-day goals and aims of the study of DNA levels in tumor cells]. / Tseli i zadachi issledovaniia soderzhaniia DNK v opukholevykh kletkakh na sovremennom étape.

Aims and tasks of the investigation of the DNA contents in tumour cells are discussed. It is supposed that DNA aneuploidia is a specific sign of malignant cells. Such supposition permits solving the problem of quantitative identification of malignant cells in the complex cell populations and determination of their quantity. Certain conditions necessary for solving this problem are considered.

[Cytological variants of lymphogranulomatosis]. / Tsitologicheskie varianty limfogranulematoza

It is shown that in the course of a cytological investigation it was possible not only to diagnose lymphogranulomatosis but in the overwhelming majority of cases to determine a morphological variant of the disease in accordance with Lukes et al. classification. Cytological pictures of the three histological variants of lymphogranulomatosis are described: mixed-cellular, reticular and nodular sclerosis. Cytological criteria for diagnosis of nodular sclerosis are identified.
