[Study of cytoplasm streaming as a cytophysiological method in radiolabeled experiment]. / Doslidzhennia shvydkosti rukhu tsytoplasmy iak tsytofiziolohichnyi metod v radiobiolohichnomu eksperymenti.

Estimation of influence of ionizing radiation, high-frequency electromagnetic radiation and their combined action on a higher water plant Elodea canadensis has been carried out using cytophysiological method of determination of the cytoplasm streaming rate. It was shown that low-intensive electromagnetic radiation modifies reaction of the differentiated cells on radiolesion. The rate of cytoplasm streaming can be used as an informative characteristic of plant cell state in radiobiological experiment.

[The number of aberrations in aberrant cells as a parameter of chromosomal instability. 1. Characterization of dose dependency]. / Kil'kist' aberatsii na aberantnu klitynu iak parametr khromosomnoï nestabil'nosti. 1. Kharakterystyka dozovykh zalezhnostei.

Analysis of chromosome instability (CI) is of great importance in view of pollution of the environment by genotoxic factors. Frequency of aberrant cells, spectrum of chromosome aberrations, damages of aberrant cell and distribution of aberrations in the cells are the most conventional parameters of CI. We have carried out the comparative analysis of the frequency of aberrant cells and the dynamics of aberrant cell damages induced by different mutagenic factors (alpha-irradiation from 241Am, gamma-irradiation from 60Co and tioTEPA) in Allium-test. This comparative analysis denotes that the studied parameters have different dynamics characterizing different mechanisms of CI in Allium cepa L.
