[The cytogenetic action of antilymphocyte globulin on the lymphocytes of bronchial asthma patients].

Chromosomal aberration levels and frequencies of sister chromatid exchanges (SCE) in peripheral blood lymphocytes were investigated for patients with bronchial asthma treated with antilymphocyte globulin (ALG). The significant elevation of chromosomal aberration levels and SCE frequencies were revealed as compared to the healthy controls. The significant differences in chromosomal aberration levels were not observed before and after the courses of ALG therapy.

[Frequency of sister chromatid exchanges in human lymphocytes at different times of day].

Analysis of the frequency of sister chromatid exchanges in the human blood taken from normal female donors was made at 9 a. m. and 9 p.
