[Topographic anatomy of human thoracic organs in the early fetal period].

The purpose of the present investigation was to evaluate the holotopy, skeletotopy and sintopy of human heart, trachea and esophagus in the early fetal period. The quantitative evaluation of the topography of these organs was given as a result of study of 100 human fetuses aged 16-24 week with the modification of N.I.

[Various locomotor movements in the rat].

The kinematics of movements and EMG activity of the hindlimb were investigated in rats during swimming and walking. It was shown that changes in loading on the limbs were the main factor modifying the frequency, amplitude, configuration, swing time and footing time of the studied movements.
