[Adaptation of antioxidative system in rat kidneys under varying light conditions during tetrachloromethane intoxication and effect of melatonin].

The influence of varying light conditions of the state of pro- and antioxidative systems in rat kidneys has been studied. The lowest level of free radical oxidation of lipids and proteins and the highest activity of catalase and glutathione peroxidase in the rat kidneys was established in case of maximal duration of the light day. Under different light conditions the increase of malonic aldehyde and oxidatively modified proteins in the rat kidneys in case of tetrachloromethane intoxication was shown as compared with the control.

[Increase in T-cell level in the peripheral blood of women with fractures in anamnesis during postmenopause period].

44 postmenopausal patients (45-76 years of old) have been observed. Interrelationship between composition and functional activity of peripheral blood cells, TNF-alpha level in the serum and bone density in postmenopausal women has been analyzed. It was established that the increase in neutrophil activity in women with osteoporosis, the high level of immune complexes are accompanied by the high level of IgG and autoantibodies to DNA.
