ABSTRACT
It has been reported that testicular torsion leads to diminished fertility. This experimental study includes 32 mature male Wistar rats, divided into 3 groups. Group 1 (4 animals) served as a control group. Group 2 (16 animals) underwent an unilateral definitive ligature of the testicular vessels. Group 3 (12 animals) underwent right testicular torsion at 360 degrees, followed by detorsion at 4, 12 or 24 hours. Both testicles were removed at different terms after the operation and processed for histologic and enzymohistochemical studies. The results of the experiment indicate that a certain recovery of the structure and the enzyme activity may be expected only in case if the duration of the torsion lasts not more than 4 hours. After this period severe and irreversible changes in the ipsilateral testis and serious alterations in the contralateral testis occur.

The structural characteristics and inervation of the aortic wall of domestic cooks was examined on fresh material from 20 species. The author examined the basic structural elements of the aortic wall by means of histological and impregnation methods. There were regional difference and peculiarities in the structure of the wall. In its larger part the aorta was described as a blood vessel of elastic type and only in the abdominal region was characterized as a blood vessel of transitory type. There were close interrelationships between the elastic membranes and smooth cells. Data were reported on the inervation and partly on vascularization of the aortic wall. Recertor formations and neuro-cellular accumulations were discribed. An important element in the inervation of the aorta was the efferent nerve fibers, having attitude to the smooth muscle component and intramural vascular bed. The obtained results give an idea on the dependence and connection between structure, inervation and to a certain degree of vascularization.
