[Structural changes in the testis in complete removal of the pancreas and its resection].

The dog pancreas was resected completely or partially. The morphofunctional status of the testicle was examined at varying times after operation with the use of histological, histochemical and morphometric tests. The alterations discovered attest to the dependence of the structural shifts in the testicle on the type of surgery on the pancreas. Resection of the end parts caused temporary and insignificant changes in the testis. Resection of the central part with ligation and intersection of the main excretory ducts gave rise to dystrophic changes in the spermatogenic epithelium, disorders in the structural elements responsible for hormonal activity. Complete resection of the pancreas was early in affecting the morphofunctional status of the testicle. Ten to 15 days after operation profound dystrophic and atrophic changes were detectable in all the cells of the testicle. Injection of insulin postponed the animal's death, decelerated but not prevented the development of regressive changes in the testis.
