ABSTRACT
The changes of photo- and peroxide resistance of erythrocytic and lymphocytic cells of human under influence of UV and some active oxygen forms in presence of biogenic amines such as serotonin, dopamine, adrenalin, histamine had been investigated. While investigating the degree of photohemolysis of erythrocytes it was discovered that biogenic compounds raise UV stability of erythrocytic membranes. By using the method of chemiluminescence it was established that biogenic amines increased the degree of peroxide resistance of human erythrocytic and lymphocytic cells. The decrease of the level of erythrocytic diene conjugates under influence of UV by serotonin and histamine was also discovered.

Karyotypes of two bark-lice species Amphipsocus japonicus End. and Dasypsocus japonicus End. (Amphipsocidae, Psocomorpha, Psocoptera) were studied for the first time. D. japonicus displayed 2n = 16 (14 + XX/X0). The XX/X0 sex chromosome system observed in this species is characteristic of the order Psocoptera. A. japonicus showed 2n = 16 (14 + neo-XY). This is the first observation of the neo-XY sex determination system in Psocoptera. In this species a large amount of constitutive heterochromatin was found in the original X-part of the neo-X chromosome.
