The anatomical structure of the tomato (Lycopersicon esculentum Mill.) pericarp was studied in the fruits of five determinant field cultivars. The fruits of the examined cultivars differed in their mechanical properties. Fruits of cultivars which are firm and resistant to injury (Kecskemeti 886j-2, Campbell 28), moderately firm and resistant (Atma, Wenus) and soft, susceptible to injury (line No 155/84) were examined. The pericarp of the cultivars which have fruits resistant to injury had an approx. 200 µm thick covering layer (epidermis plus cuticle plus hypodermis) whereas that of fruits susceptible to injury was only 100 µm thick. In the fruits resistant to injury the cuticle penetrated deeply into the hypodermis, the epidermal cells were flattened and the hypodermis was composed of 4 - 5 rows of cells. The tomato fruits resistant to injury had a thick cuticle layer on their tangential walls — whereas those more susceptible had a thick cuticle layer on these walls.

Background: Congenital heart diseases (CHD) are the leading cause of birth defect-related deaths. Multidedector computed tomography (MDCT) plays an important role for imaging CHD in addition to echocardiography and provides a comprehensive evaluation of complex heart malformations for the referring cardiologist. The aim of the study was to evaluate the utility of MDCT in the assessment of CHD. Materials and methods: A 102 patients with CHD were investigated after initial assessment by echocardiography. The information obtained by MDCT and findings of echocardiography were reviewed together by paediatric cardiologists and cardiac radiologists. Perioperative anatomic descriptions, wherever available (n = 34) formed the gold standard for the comparison. Results: The clinical consensus diagnosis defined 154 cardiovascular lesions in the patients. The results were classified in groups. We present the appearance of various congenital cardiac lesions seen in clinical practice. Conclusions: MDCT provides important information about anatomic details of CHD for the referring cardiologist. The evaluation of different anatomic structures such as heart, great vessels, lungs and abdomen is possible in one acquisition with this technique. (Folia Morphol 2013; 72, 3: 188–196)

Cuttings of R. ponticum were treated or not with ‘Ukorzeniacz AB’ containing IBA and NAA, and placed in rooting medium (temp. 21°C). Transverse sections were made of the bases of the cuttings removed from the soil after 2; 3; 4; 5 and 6 weeks. Meaningful anatomical changes in anatomical structure of R. ponticum cuttings connected with wound-healing process could be seen during rooting. In first two weeks periderm in cortex and callus from cambium and phloem emerged as a response to wounding of cuttings. After 3 weeks initiation of wound xylem started in callus. It developed very intensively and did not depend on the way of cutting treatment. Application of auxins did not or not considerably influenced the anatomical changes in stem structure of R. Ponticum during rooting – proliferation of new xylem was similar in control cuttings and in cuttings treated with rooting stimulator ‘Ukorzeniacz AB’, although it stimulated initiation of root primordia. Adventitious root formation occurred only in cuttings treated with ‘Ukorzeniacz AB’, in which numerous root primordia could be observed after 3 and more weeks of rooting. In control cuttings there was none of them even after 6 weeks of rooting.

In Poland Scorzonera hispanica L. is rare in the wild. This species is used as a vegetable and medicinal plant. Currently, attempts are being made to introduce this plant into cultivation in Poland. In this study, comparative analyses were conducted of the epidermis surface micromorphology and anatomical structure of the leaves of S. hispanica 'Maxima' and 'Meres'. The investigations were performed using fluorescence, light and scanning electron microscopy. The cuticle on the surface of epidermal cells is smooth or striated. In the epidermis, there are anomocytic stomata. The stomatal index in the epidermis of the studied cultivars is 9.3-11%. In the midrib of the leaf, there is an aerial cavity which occupies a substantial area. In this place, cracking and breaking of the leaf blade were observed. Over the aerial cavity under the adaxial epidermis, there is a single layer of collenchyma cells and 1-2 rows of parenchyma cells. Tangential collenchyma is also present between the abaxial epidermis and large vascular bundles located in the midrib and on both sides of the large vascular bundles in the lamina. This tissue strengthens the leaf margin. The mesophyll cells located in the abaxial epidermis of the midrib form protrusions surrounding the large vascular bundles. The leaves of S. hispanica represent the equifacial type.

The large intestine of eight Micro mammalia species, of the orders Insectivora (Sorex minutus, Sorex araneus) and Rodentia {Sicista betulina, Clethrionornys glareo- lus, Microtus oeconomus, Apodemus flauicollis, Mus musculus, Cavia porcellus) were studied. Both the length and surface area of the mucosa of the alimentary canal are strongly associated with food hydration, In M. oeconomus, feeding exclusively on green parts of plants, the large intestine dominates the totai length of the alimentary canal (35% of length). In omnivorous S. betulina and A. flavicollis, the length of the large intestine is 30% of total length of the canal and only 20% in M. musculus fed with dry and granulated food. The large intestine of the rodents (but S. betulina) is divided into caecum, colon and rectum. The caecum is best developed in M. oeconomus, where the relative value of the caecum is 5.54 mm/g and the surface area is 97.07 mm2/g of the body weight and least developed in M. musculus - 1.24 mm/g and 13.34 mmJ/g. In insectivorous shrews, the large intestine is very short and non-differentiated into segments. Its proportion in the length of the alimentary canal amounts only to 6.5%. The relative value of the length of the large intestine is between 1.34 mm/g of body weight (S, araneus) and 2.01 mm/g (S. minutus).

Background. The omnivorous freshwater loach, Lepidocephalichthys guntea (Hamilton, 1822) inhibiting unique ecological niche where oxygen content is low. Its alimentary canal is remarkably short, which is surprising considering the fact that this fish is an omnivore. This peculiarity can be correlated with the specific nature of food. Therefore, the aim of the present study was to investigate the mucosal adaptation of the intestine in adult L. guntea with respective digestive- as well as respiratory function. Materials and Methods. The surface design of the mucosa of different sections (anterior, mid, and posterior) of the intestine of L. guntea were studied using light and scanning electron microscope following commonly accepted procedures. Results. The mucosa of the anterior intestine was provided with various types of mucosal folds and crowded with almost closely oval or rounded columnar epithelial cells with prominent microridges. The irregular mucosal surface of the mid intestine was exemplified by regularly spaced columnar epithelial cells with minute and prominent microridges/microvilli. On the contrary, irregular mucosal folds with stumpy villi were detected in the posterior intestine. The mucosal surface of that region was made up of columnar epithelial cells containing inconspicuous microridges. In that region the submucosa was provided with increasing number of blood vessels. Various cellular elements in the anterior and mid intestine were accordingly adapted to serve the important functions of absorption and gas exchange. However, the arrangement of low mucosal folds and dense blood capillaries in between the folds in the posterior intestine unequivocally suggested its respiratory role. Conclusion. The micro-architectural pattern and cellular architecture of the anterior intestine and middle intestine of L. guntea unequivocally suggests that these two regions are adapted to serve major role of digestion and absorption process. However, major changes that appear in the posterior intestine are considerably reduction of the absorptive area and the penetration of blood capillaries in between the columnar epithelial cells. Therefore, the posterior intestine of L. guntea is probably adapted to suit its role for aerial respiration. However, further investigation is needed the detailed physiological processes involved for aerial respiration in the region concerned.
