The regional morphological characteristics of the endothelium of the human thoracic aorta in perfusion fixation

: The method of electron microscopy was used to study the morpho-functional state of pancreatic islands of human fetuses at different terms (10-54 h) after clinical death. Within the periods of time in question the island secretory cells preserve the structure characteristic of each type (B, A, D). The development of symptoms of postmortem autolysis of the pancreatic island is not a chaotic fleeting physico-chemical reaction and is characterized by a definite sequence of cytological changes of endocrinocytes. A conclusion is made that cadaveric material of the pancreas is good for preparing the pancreatic island culture for using it in the following tissue substituting therapy of patients with diabetes mellitus.
