RESUMEN
Additivity of clastogenic effects of two doses of radiation to human peripheral blood lymphocytes is considered. We compare the effects of combined tritium and gamma irradiation with the sum of the effects of either irradiation administered separately. Our solution is based on combination of de Moivre and Cramèr-Slucky theorems. The results for 14 subjects where the deletion types of chromosome aberrations were counted indicate a Normal distribution of the sample additivity index, oscillating non-significantly around zero, with one outlier towards adaptivity and another towards synergism of the effect of the two doses absorbed by the cells.

In randomly selected thousands-sized samples of the Central Slovakian population the following proportions of antigen (antibody) positivity were found: 0% for Mg (0.158% for anti-Mg), 0% for Nya (0.008% for anti-Nya), 0.284% for Sc 2 (0% for anti-Sc 2) and 0% for Wra (0.035% for anti-Wra). The difference between the antigen and antibody occurrence is statistically significant (alpha = 0.01) for Mg as well as for Sc 2. The found Mg and Nya frequency is comparable to that in the world but is significantly lower than in Switzerland and Norway, respectively; the frequency of antigens Sc 2 and Wra in Czechoslovakia is generally significantly lower.

Data on the amount of uroepithelial squamous cells released into the fluid of urethral expulsions were obtained in a 37-year-old multipara by daily five consecutive repeated applications of the digital stimulation technique, carried out over the period of one and a half of her menstrual cycle. During the secretory phase of the cycle the rate of the cellular component was far higher than during the proliferative phase. These quantitative biometrically analysed data provide a complementary picture to the qualitative cytological changes of uroepithelial squamous cells occurring during the menstrual cycle that have been reported so far.
