Argyrophil and argentaffin APUD cells in the human female prostate homologue and urethra.

In the female prostate homologue and urethra, numerous argyrophil and rare argentaffin cells were found. Grimelius method displayed the closed and open types of argyrophil cells in all cases this study. The findings indicate the possibility of endo/para/crine activity of the female prostate homologue and urethra and support the opinion on the non-vestigial role of the prostate homologue in woman.

[Seasonal dynamics of the gastric APUD cell count in a hibernator].

Light microscopy was applied to study variation in the composition and number of apudocytes in the gastric epithelium of red-cheeked sousliks over time. During hibernation, the content of serotonin-producing EC cells was elevated. This is in agreement with serotonin involvement in the maintenance of the hibernation state. The number of non-EC cells taking part in digestion, which does not occur during hibernation, was lowered. Spring awakening was accompanied with an increase in the number of non-EC cells and the lack of significant changes in cells. In souslics, which were active in winter, the content of non-cells was high, since the animals continued feeding on, and the content of EC-cells was elevated similarly to that in hibernating animals, which could be explained by genetic dependence. The number of apudocytes in the gastric mucosa was discovered to correlate in the main with the features of their function at different seasons.

[Study of gastric APUD cells in gastroduodenal hemorrhage].

It was found that in patients with gastroduodenal hemorrhage the number of serotonin-, histamine-, and melatonin-producing apudocytes in the gastric mucosa increases while the number of cells producing gastrin, adrenaline, and noradrenaline reduces. In timely arrest of hemorrhage, the primarily increased number of melatonin-producing apudocytes diminishes with time from the onset of bleeding and reaches normal values gradually. The essential differences in the content of melatonin- and noradrenaline- producing apudocytes in patients with and without hemorrhage allow this morphological sign to be used as diagnostic and prognostic criteria in gastroduodenal hemorrhages.
