Ghrelin and motilin were compared with regards to their effects on gastrointestinal motility. The structure of their molecules is not very different and they act via similar receptors. Both induce phase three of MMC and enhance contractions during the interdigestive state. Their action can occur via central or peripheral mechanisms, mostly as neuropeptides, although direct action on smooth muscles cannot be excluded. However, the spectrum of ghrelin action is broader and also comprises the digestive period. The role of ghrelin in the gastrointestinal tract is substantial and its action seems to be physiological. Ghrelin is a new hormone-candidate in the gut.

The lacrimal gland (LG) and superficial gland of the third eyelid (SGTE) belong to accessory organs of the eye. The aim of the present studies was to evaluate the histological, histochemical and fine structure of the LG and SGTE obtained from 3 adult females and 2 adult males of alpaca (Vicugna pacos). The LG was situated in the dorsolateral angle of the orbit between the dorsal rectus and the lateral rectus muscles. The SGTE was located between the medial rectus muscle, the ventral rectus muscle and was partially covered by the ventral oblique muscle of the eyeball. There were no effect of gender on the morphometry of examined LG and SGTE. The third eyelid resembles an anchor in shape. During histological and ultrastructural analyses using light and transmission electron microscopy, it was established that the LG and SGTE are tubulo-acinar glands with mucoserous characters. The LG contains either lymphocytes or plasma cells, while SGTE had rare plasma cells and numerous lymphocytes in connective tissue. The cartilage of the third eyelid was composed of hyaline tissue. Numerous aggregations of lymphocytes as lymph nodules in bulbar surface of the third eyelid were observed. The LG and SGTE secretory cells exhibited a similar ultrastructure appearance in electron microscopic examination, with secretory cells tightly filled with intracytoplasmatic secretory granules and numerous clusters of mucus of different sizes which were observed in the peripheral cells compartment.

Background: Coronary vessels have been widely studied in many species of domestic and wild mammals. However, there are no available literature reports describing the morphology and morphometry of the coronary ostia of the European bison (Bison bonasus). The aim of this study was to measure the area of the coronary ostia and assess their localisation in the coronary sinuses of the aortic root in the European bison. Materials and methods: The study material comprised 27 hearts from European bison of both sexes (16 males and 11 females), from 3 months to 26 years old, inhabiting the Bialowieza Forest (Bialowieza National Park, Poland). The animals were divided into two age groups: ≤ 5 years (group I) and > 5 years (group II). Results: In all the studied European bison, the aortic valve consisted of three semilunar leaflets, left, right and septal. The ostia of both coronary arteries were located beneath the sinotubular junction. The dimensions of the left coronary ostium were larger than those of the right coronary ostium. They were longer by on average 4.5 mm (95% confidence interval [CI] 3.5–5.6 mm), they were wider by on average 1.6 mm (95% CI 1.0–2.2 mm) and they had a larger area by on average 31.6 mm² (95% CI 22.7–40.5 mm²). This was evident both in young and in adult bison. After adjusting for age, there were no differences in the ostia dimensions between males and females. There were no differences in the structure of the left and right coronary arteries in nine animals. In the remaining 18 animals, there were variations in the morphology of the coronary ostia or additional ostia. Conclusions: Because of the anatomical similarity between the European bison and other ruminants, the results of this study can be applied to the other species including endangered ones.

The aim of the study was to investigate the morphology and morphometry of ramifications of the aortic arch in domestic shorthair cats in relation to the sex of the animals. The morphological study was performed on 61 hearts of adult domestic shorthair cats of both sexes, preserved in the 10% solution of formalin. Measurements of the area of openings of basic branches and distances between them were performed. In cats we can observe a double type of direct ramification of the aortic arch: the brachiocephalic trunk and the left subclavian artery. In all studied cases, the surface area of the ostium of the brachiocephalic trunk (SABT) was greater 4.94 ± 1.35 mm² than the surface area of the ostium of the left subclavian artery (SALSA) 2.38 ± 0.88 mm². The average difference between the opening area of the above vessels (r) amounted to 2.56 mm². In the studied group of cats, the distance between the openings (d) varied between 0.5 and 4.37 mm. In the post hoc comparison of the mean values no statistically significant differences were found between the population of males and females. Fundamental changes in the structure of openings were found in two females. The first one concerned a secondary division of the brachiocephalic trunk opening and the second one – a secondary division of the opening of the left subclavian artery in the area of their parting from the aortic arch. CT angiography or MRI angiography is the method of choice for diagnosis of vascular disorders or malformations. The knowledge of the aortic arch morphology in various species of animals is a prerequisite for a correct assessment of the results of imaging tests.
