| Abstract: | A cytogenetic investigation of a group of prematurely born babies was carried out during the first months of their life (at ages of 0 days, 5-7 days, 2-4 weeks), as well as of a group of infants born in proper time and having a normal weight. As it was shown by the analysis of chromosome aberrations, frequencies of aberrant cells in babies at ages of 0 days, 5-7 days, 2-4 weeks and in those that have endured some bacterial or viral infection were 1,96% (0.22 aberrations per cell), 3,38% (0,037 aberrations per cell), 4,92% (0,053 aberrations per cell) and 6,73% respectively. The role of infection of drugs in the increase of the frequency of aberrant cells is also indicated by the investigation of babies born in proper time and having normal weight, that have endured an acute respiratory disease. In this group of children the frequency of aberrant cells was 5,3%. However, it is impossible to assess the role of each of these factors separately, since their effect on the organism of prematurely born babies is simultaneous from the very moment of birth. |
