Abstract
As traumatic brain injury (TBI) is one of the major causes of permanent disability, there is increasing interest in the long-term outcome of TBI. While motor deficits, cognitive impairment and longer-term risks of neurodegenerative disease are well-established consequences in animal models of TBI, pain is discussed less often despite its high prevalence. The current study addresses the need to characterize the extent of chronic pain and long-term behavioral impairments induced by moderate lateral fluid percussion injury (latFPI) in mice up to 12 months post-TBI and evaluates the validity of the model. Adult male BALB/c mice were subjected to latFPI, and the results were compared with outcomes in sham-operated mice. Mouse behavior was assessed at 1 and 7 days and 1, 3, 6, 9, and 12 months post-injury using sensory-motor (neurological severity score, NSS), cold (acetone) and mechanical sensitivity (von Frey), depressive-like behavior (tail suspension), locomotor (open field), motor coordination (rotarod) and cognitive (Morris water maze, y-maze, passive avoidance) tests. Animals with TBI demonstrated significantly higher NSS than the sham-operated group for up to 9 months after the injury. Cold sensitization was significantly increased in the contralateral hind paw in the TBI group compared to that of the sham group at 3, 6, and 9 months after TBI. In the von Frey test, the withdrawal threshold of the contralateral and ipsilateral hind paws was reduced at 6 months after TBI and lasted for up to 12 months post-injury. latFPI induced progressive depressive-like behavior starting at 6 months post-injury. No significant deficits were observed in memory, motor coordination or locomotion over the 12-month assessment period. The present study demonstrates that moderate TBI in mice elicits long-lasting impairment of sensory-motor function, results in progressive depression and potentiates peripheral pain. Hence, the latFPI model provides a relevant preclinical setting for the study of the link between brain injury and chronic sequelae such as depression and peripheral pain.

Abstract
The temporospatial patterns in the localization of hexose transporters as well as in the quantitative and qualitative differences of glycoprotein mucin produced by the goblet cells of broiler chicken (Gallus gallus domesticus) small intestine during their first postnatal month were studied. The integral membrane proteins glucose transporter-2 and -5 (GLUT-2 and GLUT-5) that facilitate the transport of hexoses across epithelial cell layers that separate distinct compartments in organism were detected in the chicken intestinal epithelial cells using immunohistochemical labeling with polyclonal primary antibodies Rabbit anti-GLUT-2 and Rabbit anti-GLUT-5 (IHC kit, Abcam, UK). The chemical composition of mucin (neutral, acid) was carried out by applying the histochemical reactions by Alcian-Blue and periodic acid-Schiff methods. The results revealed presence of the hexose transporters GLUT-2 and -5, immunolocalized in the enterocytes of broiler's small intestine and the temporospatial pattern of the density of goblet cells of intestinal mucosa as well as the chemical composition of mucin produced by the goblet cells in chicken immediately after hatching and in 30-days-old chicken's. Simultanously, when goblet cells remained unstained with both antibodies in intestinal epithelium in chicken of both ages or some moderate staining was noticed in 30-days-old chickens' ileal epithelium, the increase of neutral and acid mucin- containing cells per area unit in both segments of the small intestine was detected from the first day after hatching to 30 day of life and the densilty of goblet cells was found to be higher in ileal than in duodenal region.

Abstract
The knowledge about transport of sugars in animals and birds gastrointestinal tract is very important for science as carbohydrates are the main energy source of food. Since until now there is few information about the localization of glucose transporters - integral membrane proteins that mediate the transport of glucose and related substances across the cellular membranes - in birds gastrointestinal tract, the aim of the present study was to localize glucose transporters-2 and -5 (GLUT-2 and -5) in three parts of the ostriches gastrointestinal tract – proventriculus, duodenum and ileum - comparatively in ostrich chicken in their early ontogenesis period. Material from the superficial gland zone of the proventriculus, duodenum and terminal zone of the ileum were collected from eight female ostriches (Struthio camelus var. Domesticus): two chickens after hatching, three 7 and three 30-days old ostriches. The material was fixed with 10% formalin, embedded into paraffin, slices 7 μm thick were cut followed by immunohistochemical staining with polyclonal primary antibodies Rabbit anti-GLUT-2 and Rabbit anti-GLUT-5, carried out according to the manufacturers guidelines (IHC kit, Abcam, UK). The results showed that the staining for both antibodies was weaker in all parts of the gastrointestinal tract of ostriches after hatching compared to 7 and 30 days old ostriches showing that the gastrointestinal tract of ostriches immediately after hatching is not entirely capable of transportation of carbohydrates. The results of our study may indicate the possibility of a close relationship between feeding and the ability to transport sugars in the gastrointestinal tract.

Abstract
The role of goblet cell secretion, containing mucopolysaccharides, in the formation of a protective barrier of intestinal mucosa and transportation of the intestinal content has been described quite extensively. However, information on the quality composition of mucopolysaccharides and its changes in the intestinal tract of ostrich chicks, especially in the large intestinal segments, is unavailable. In the current study, ostrich embryos/chicks (n = 6/36) of both sexes were used shortly before hatching and during the first months of the post-hatch period. Tissues for histology were taken from the large intestine: the medium segments of the caecum, proximal and distal parts of colon. By using histochemical reactions, the differentiation of goblet cells as well as chemical composition of mucopolysaccharides was carried out. The cells contained acid (AB+), neutral (PAS+) and mixed (AB/PAS+) mucopolysaccharides. The number of goblet cells in the large intestine per unit area of mucosa increased towards the cloaca, and it was the highest in the distal part of the colon. The qualitative goblet cell composition in different large intestinal parts was different in all ages. In the caecum, goblet cells containing acid and mixed mucopolysaccharides dominate post-hatch, whereas in the colon, goblet cells containing acid mucopolysaccharides predominated. The most rapid changes in the qualitative goblet cell composition occur during the first week post-hatch when in all the intestinal segments the proportion of cells containing acid mucopolysaccharides continuously increased.

Abstract
Abstract
The biopsy of live animal testes is an important clinical manipulation to control spermatogenesis and reproductive system pathologies. The aim was to develop a method of boar testes biopsy using a biopsy gun with ultrasound guidance and to investigate the influence of this procedure on the boar testes parenchyma and quality of ejaculate. The biopsy was carried out in six 8-month-old boars. Fourteen days prior to and 21 days after biopsy, the quality of ejaculate was examined (weight of ejaculate; concentration and motility of spermatozoa) with a seven-day intervals. Ultrasound images of the testes parenchyma were recorded three times: directly before and 15 minutes after the biopsy, then 21 days after the procedure. The testes biopsies of generally anesthetized boars were performed with the biopsy gun for needle biopsy with a 12cm long, disposable 16-gauge needle 1.8mm in diameter (Vitesse) through 1cm skin incision in the depth of 1.2-1.6cm of parenchyma. Fifteen minutes after the biopsy, macroscopic injures of the parenchyma of all the boar testes were not detected in the ultrasound image. Twenty one days after biopsy, the hyperechogenic line 0.1-0.2cm in diameter was seen in the testes parenchyma of six boars in the depth of 1.2-1.6cm. The biopsy of boar testes did not influence the quality of boars ejaculate. The ultrasonographic examination of boar testicles before the biopsy reduced possibilities to traumatize large blood vessels of the testes. A perfect boar testicular biopsy was easy to perform using ultrasonographic examination in the pigsty conditions.
