Opis:: The aim of the present paper was to find out by in vitro chromosomal aberration test using human lymphocytes whether cysteine has anticlastogenic properties towards a well-known mutagen - mechlorethamine. The lymphocytes tested were obtained from three healthy donors. Two doses of cysteine (1.0 and 2.0 μg/ml) and three doses of mechlorethamine (0.1,0.2 and 0.3 μg m⁻¹) were tested. It was found that cysteine had anticlastogenic properties and that it reduced the number of metaphases with chromosomal aberrations induced by mechlorethamine.

Opis:: The effects of mutagens on DNA replication and DNA repair were studied in peripheral blood lymphocytes (PBL) obtained from 21 healthy subjects, 2 samples from healthy heterozygote of Xeroderma pigmentosum (XP) and 2 samples from patient with clinically recognised XP. Inter-individual variations were found in DNA replication and in the level of spontaneous DNA repair measured under standard culture condition. Exposure of human PBL proliferating in vitro to B(a)P was followed by a partial inhibition of replicative DNA synthesis in all subjects and by an induction of DNA repair in healthy subjects. In XP patients DNA repair synthesis remained at the level attributed to spontaneous DNA repair. The response to mutagen varied individually. Results were analysed statistically. It was established that the studied indices of DNA synthesis correlate well with each other. The highest correlation was found between the levels of spontaneous and B(a)P-induced DNA repair. It is concluded that the level of spontaneous DNA repair is predictive for an estimation of cells ability to repair DNA damage. Inter-individual variations in the inhibition of DNA replication and in DNA repair synthesis are also dependent on the type of mutagen as shown by effects of other mutagens. Different effects of mutagen exposure on the inhibition of DNA replicative synthesis and induction of DNA repair can be explained by genetically controlled differences in the activity of enzymes responsible for mutagen processing and lesion removal.

Opis:: It has been suggested that mutagen sensitivity is a constitutional factor which may be useful in identification of patients with an increased risk for the development of tumors. In this study, the chromosome sensitivity to bleomycin was measured according to Hsu in patients with hereditary non-polyposis colorectal cancer (HNPCC), sporadic colorectal cancer and in control persons with no tumor history in family. In vitro lymphocytes were exposed to bleomycin according to Hsu and chromosomal damage was quantified by scoring breaks of 100 cells. A significant difference (P < 0.01) in the mean number of breaks per cell (b/c) was found between HNPCC patients (0.59 ± 0.14; n = 12; mean age 55.4 yrs) and control individuals (0.35 ± 0.13: n = 12; mean age 55.8 yrs). In contrast, patients with sporadic colorectal cancer showed a mean b/c value of 0.43 ± 0.14 (n = 14; mean age 63.4 yrs) which was not significantly higher than that in control individuals for this group (0.42 ± 0.15; n = 14; mean age 63.1 yrs). Selenium protected lymphocytes of HNPCC patients against bleomycin activity in vitro.

Opis:: Acetylsalicylic acid (ASA) and α-2-pyrazylidene-α-cyano N-butyl acetamide (PD-101), a new antiaggregatory pyrazine derivative were tested for their genotoxicity in human lymphocytes in vitro using the sister chromatid exchange (SCE) technique. Both compounds were found to be inactive in inducing SCE in concentration from 1 µM up to 1000 µM. The agents displayed inhibitory effect on cell kinetics.

Opis:: Five newly synthesised monophosphates of two pyrimidine acyclonucleoside series, namely 1-N-[(2’-hydroxy)ethoxymethyl] and l-N-[(l’,3’-dihydroxy)- 2’-propoxymethyl] derivatives of 5- and 5,6-alkylated uracils were tested in vitro for chromosome aberrations and sister chromatid exchanges (SCE). Metaphase plates were obtained via microculture of human lymphocytes from heparinized peripheral blood. The compounds were tested in doses: 10, 20, 40, 80 and 150 µg per mL of culture. The tested compounds induced mainly chromatid gaps, less frequently chromosome gaps. A low number of mitoses with chromatid and chromosome breaks, acentric fragments, dicentric chromosomes and exchange figures were also observed. The tested compounds in doses: 40, 80 and 150 µg per mL, doubled or tripled the percentage of cells with chromatid gaps and chromosome gaps as compared to the control. The percentage o cells with aberrations (excluding gaps) induced by the tested compounds in all doses did not exceed 2%. The tested compounds induced a higher number of SCE per cell but less than double frequency as compared to the control. SCE frequencies and replication index (RI) values varied depending on the examined compounds. For the highest dose of the tested compounds (150 µg per mL) a significant decrease in RI values was observed for l-N-[(2’-hydroxy)ethoxymethyl]-5,6-tetramethyleneuracil monophosphate and for l-N-[(2’-hydroxy)ethoxymethyl]-5,6-dimethyluracil monophosphate. So far, the results have indicated potential clastogenicity of all the tested compounds except acycloguanosine monophosphate.
