Pathomorphological Changesin the Small Intestine and Liver of the European Beaver (Castor fiber L. 1758): a case study.The aim of thestudy was to examine and describe the morphology and patomorphology of small intestine and liver of European beaver (Castor fiber). In natural environment beavers are in constant contact with various both internal and external parasites. Histological analysis revealed the pathological changes within the digestive track and liver indicating long-term inflammation. It was hypothesized that the observed inflammation was caused by the parasites not related to beavers so far.

Background: Different pathological affections of the small intestine cause corresponding morphological and functional changes. The present study was aimed to assess intestinal trehalase activities during ischemia and following reperfusion, correlate them with the pathological changes and determine whether trehalase could be used as a biochemical marker of the intestinal ischemia, ischemia - reperfusion injury. Material and methods: Wistar rats, randomly divided into 5 experimental groups (IR) (each n=15), were subjected to one hour mesenteric ischemia followed by 0, 1, 4, 12 and 24 hours of reperfusion. As a control group sham operated animals were used (n=15). The activity of trehalase was determined using an adapted Dahlqwist method. The range of intestinal injury was determined using histological (histopathological injury index and goblet cell quantification) and immunohistochemical (Ki67, InSitu TUNEL) methods. Results: The highest activities of trehalase were recorded in the control group (C=4.42±0.373 μmol/mg/h). The most altered intestinal histology detected in group IR1 was accompanied by the lowest trehalase activity (IR1=0.97±0.209 μmol/mg/h; p < 0.001 C vs. IR1). Improved histological structure in the remaining reperfusion periods correlated with increase in trehalase activity. Almost normal mucosal histological architecture and 72% of the enzymatic activity were restored after 24 hours of reperfusion (IR24=3.20±0.266 μmol/mg/h; p < 0.01 IR1 vs. IR24). Conclusion: The correlation between intestinal histology and trehalase activities during intestinal injury has been shown. Trehalase activity is closely associated with the status of the histological architecture of the small intestine.

Our study investigated morphological changes in enterocytes of adult Japanese quails that were given cadmium (CdCl₂) perorally and individually by tube, dissolved in water at a dose of 0.24 mg Cd per animal per day, for 57 and 118 days. The aim of our study was to observe chronic effects of cadmium on the structure of duodenal epithelium by means of light microscopy (LM) and transmission electron microscopy (TEM). On day 57, following peroral administration of cadmium, necrotizing enterocytes were found in the apical part of intestinal villi and their occurrence was only sporadic. Particularly on day 118 following cadmium administration, we were able to observe clusters of 2-3 necrotizing cells in the apical part of intestinal villi. However, the structure and ultrastructure of goblet cells was normal. The most notable finding in ultrastructure of all enterocytes of treated animals was the damage to cell organelles. Mitochondria and cisternae of the endoplasmic reticulum were more or less damaged and the cytoplasm contained flocculent material, particularly in the basal part of enterocytes. Some enterocytes exhibited signs of necrosis, shrivelled nucleus and damaged organelles within the markedly electrondense cytoplasm. Microvilli on the apical surface of these enterocytes were damaged and disintegrated. Junctions between cells of the intestinal epithelium were disturbed, and a present of intracellular plaques associated with the adhering and occluding junctions was observed. Cadmium caused the formation of gaps within the specialized junctional complexes, and injury to enterocytes results in the breakdown of the intercellular attachments and the sloughing of the injured cells into the intestinal lumen.
