The aim of this study was to investigate the variations as well as the length of A. cystica and its branches in pigs using corrosion casting method with the self-polymerising resin Duracryl® Plus. The method included several steps: hepatectomy, precasting treatment, injection of Duracryl, polymerisation of casting medium, corrosive treatment, cleaning of the corrosion casts, air-drying and preservation of casts. The livers were collected from 12 male 6-month-old pigs (crossbred Landrace×Danube White). With regards to the beginning of A. cystica, 4 variations were observed and grouped as follows: variation A  A. cystica detached from R. dexter medialis, together with R. quadratus (variation A1), or alone (variation A2); variation B1 – A. cystica originated from A. gastroduodenalis, or was a branch of the common trunk (R. dexter) (variation B2). The metric data were processed by GraphPad Prism 6 for Windows. Clinically relevant relations between А. сystica, Ductus cysticus, A. celiaca and R. sinister also were described. The new information re-ceived about the blood supply of the gallbladder would contribute to the understanding of the etiology of postoperative complications as a result of surgical interventions in this location and for their prevention.

Polycaprolactone (PCL) and Fe2O3/PCL nanocomposites sheets/films were prepared by solution casting method. The morphological study illustrated that Fe2O3 nanoparticles were dispersed and embedded well within the PCL matrix. The size of Fe2O3 nanoparticles were below 250 nm. The thermal stability of Fe2O3/PCL nanocomposites was lower than neat PCL, which might be due to Fe2O3 (act as catalyst during the thermal degradation of PCL). The differential scanning calorimetry (DSC) analyses show that the crystallization temperature of the nanocomposites was slightly enhanced as compared to neat PCL. The polarized optical microscopy (POM) analyses showed that the size of Fe2O3/PCL nanocomposites spherulites were smaller than neat PCL. The photodegradation study presented that the nanocomposites photodegraded higher quantity of rhodamine B dye as compared to neat PCL. The neat PCL degraded about 24 and 72% while Fe2O3 (6 wt%)/PCL nanocomposites degraded about 72 and 98% of dye within 2 and 10 h, respectively.
