Background: The aim of this study was to clarify the arterial supply of the skin covering the prominent part of the thenar eminence in order to describe the possibility and potential for harvesting a pedicled or a free flap from the thenar eminence. Materials and methods: The arteries were studied in 30 post-mortem specimens of human hands; 3 previously perfused with 4% formaldehyde solution, and injected with black India ink, and 27 injected with methyl-methacrylate and afterwards corroded in 40% potassium hydroxide solution. Results: In all hands we found two little palmar arteries coming from the anatomical snuff-box portion of the radial artery. We labelled the first (proximal) branch as the middle thenar artery, because it supplies the middle third of the thenar eminence skin. Its diameter varied from 0.25 to 0.55 mm (mean 0.4 mm). The distal, more prominent branch of the radial artery, vascularised the lateral third of the thenar eminence skin, and was named the lateral thenar artery; its diameter ranged from 0.40 to 0.90 mm (mean 0.67 mm). The superficial palmar branch of the radial artery, always present, was classified as: hypoplastic, average or prominent, with a diameter ranging from 0.8 to 2.7 mm (mean 1.47 mm). Conclusions: Three individually developed branches of the radial artery supplied the skin of the thenar eminence. Cutaneous branches of these three arteries were interconnected via anastomotic vessels. (Folia Morphol 2017; 76, 2: 232–238)

This study investigated properties of starch-based edible films with oregano and black cumin essential oil addition. Essential oils addition positively affected film swelling (decreased due to essential oil addition), mechanical properties (tensile strength decreased while elongation at break increased), and water vapor barrier properties (decreased along with essential oils addition). Control film did not have any biological activity, which proves the need for essential oils addition in order to obtain active packaging. Oregano oil was more effective in terms of biological activity. Endothermal peak, above 200°C, represents total thermal degradation of edible films. Diffraction pattern of control film showed signifi cant destruction of A-type crystal structure. Addition of essential oils resulted in peak shape change: diffraction peaks became narrower. Principal Component Analysis has been used to assess the effect of essential oils addition on final starch-based edible films characteristics with the aim to reveal directions for the film characteristics improvement, since the next phase will be optimal film application for food packaging.
