The success of using soft tissue transplants is enough for their spreading in the clinic, but the need to cover the surface, where the transplant was taken from, can be forgotten. It can lead to long-term discomfort of the patient in real life, in some cases to complications alike bleeding; We performed the analysis of the use of different new xenogenic resorbable membranes created within our University in compare with the natural healing of oral mucosa defects in the experiment in vivo on 36 rabbits after performing of the surgical wound on the palatine side (5x5 mm). All animals were separated (divided) for 3 groups: #1 group of control and main groups #2 and #3, where we used pericardium and collagen film for covering mucous defects. We assessed the edema, hyperemia in the operation side, the pain according to animal behavior, the histological picture after animals completion of the experiment (on 3rd, 6th and 10th days); The decrease of clinical signs of inflammation in groups of collagen and pericardium films use (p<0.05) was statistically confirmed. Analysis of histologic investigation of biopsy specimens has shown the faster and massive growth of soft tissue in the donor site after application of pericardium and collagen films (p<0.05). An analysis of the experiment results allows recommending their possible use for closing the donor site after taking a free gingival graft or in the zone of postoperative wound defect in the oral mucosa in clinical oral surgery after specific clinical trials.

© 2020 Glutaraldehyde (Glut) is an extensively used sterilant and fixative for the crosslinking of natural soft tissue biomaterials like bovine pericardium (BP) to provide stability and is required for its application in vivo. There is plenty of debate around the reaction mechanism of Glut with natural biomaterials. Differential scanning calorimetry (DSC) is a commonly used technique that is typically used to measure the thermal profile of polymers. However, a variation known as quasi-isothermal modulated differential scanning calorimetry (QiMDSC) has been utilised for the analysis of polymorphic transformations in both the pharmaceutical and food industries. This communication will address QiMDSC as a method for analysing soft tissue biomaterials and their crosslinking mechanisms and how it can be applied to other biomaterial applications.

An X-ray picture of tension pneumopericardium, as a transsternal transpericardial main bronchus stump occlusion complication, not previously seen after this sur-gery, is described. The clinical picture of a tension pneumopericardium and diag-nostic methods applied to determine this condition are reported. Successful elimination of complications in a somatically burdened patient was possible only due to rapid and accu-rate diagnostics of this condition.

The incidence of sarcoma increases after radiation therapy in the field of breast. The specific features of this case report are the difficulties in diagnostics of undifferentiated spindle-cell sarcoma of the pericardium and the connection between the disease and the radiation therapy for Hodgkin's lymphoma.
