[Posterior lobe of the rooster pituitary during prolonged conditioning of emotional stress].
Daily fights were chosen to kindle the situation of emotional stress in roosters. A marked decrease in contents of the neurosecretory substance and a large number of Herring's bodies in the hypophyseal lumen were observed within the 1st month. By the 60th day these signs of increased release of the neurohormones into the blood flow disappeared and the condition of hypophysis returned to the initial level. Simultaneously the intensity of the fights was reduced. The reason the normalization of hypophysis state consists, probably, in the adaptation of the roosters to the stressful situations.
