Peculiarity of the brain work of 15-16 years pupils // Tomsk State Pedagogical University Bulletin. 2000. Issue 9 (25). P. 36-38

Participants of the investigations were healthy pupils (boys and girls of about 15-16). The emotional stress which was made by a test improves the dinamics of the brain work and higher the intensivity pupil's attension. The girls of 15 - 16 years are more stable to stress. It is the first time when we discovered that the dinamics of the girls brain work depends on the type of hormonal suppling of reproductional cycle.

The Changes of Thyroid Gland Morphofunctiona! Condition under Combined Exposure of Hypokinezia and Cold // Tomsk State Pedagogical University Bulletin. 2000. Issue 9 (25). P. 51-55

The obtained data of morphofunctional condition and blood hormone levels of rats thyroid glands under 5 days exposure of hypokinezia, cold and their combination are presented. It was established that cold exposure in combination with hypokinezia gave rise to compromising reaction of thyroid gland, when there were elements of reaction to both hypokinezia and cold. Some of follicles in central gland,s zone were in condition of great functional stress, but the rest of part (it was more than 2 volume) was in deep depression of synthesis and secretion. So considerable deficiency of thyroid hormones in organism appeared and it lead to heavy breach of metabolism, weakening of the mechanisms of thermoregulation and even to the death of some rats at the end of the experiment.
