[Effect of training for loads in the ventrodorsal direction on the blood vessels of the sympathetic trunk of the rabbit brain].
Thirty six rabbits underwent special training to get a state of being trained. In a centrifuge with a 1 m radius 18 animals got ventro-dorsal gravitation stress according to schedule N 1 (with limberung-up) and 18 animals according to schedule N 2 got gravitation stress without limbering-up. After training the animals had a 2, 3 and 4-week rest. Then a part of animals was killed and served as control and the others were subjected to a single exposure to stress of the same direction (10 units for 40 min). This stress was unendurable for untrained animals. By means of injection, clearing, measuring the vessels and histologically it was shown that the trained state was reached according to schedule N 2 and retained for 3 weeks. It was also confirmed by survival of animals and the state of the vessels of the sympathetic trunk. Training according to the 1st schedule resulted in cumulation.
