Opis:
The aim of this study was to evaluate the influence of the surface microstructure of chitosan films on the contact angle. Films without plasticising additives made of chitosan or regenerated chitosan were selected for the tests. A sessile drop method based on the European Pharmacopoeia was used to determine the contact angle. Due to the method of film production, the contact angle measurements were made on both the top and bottom surfaces of the film. For chitosan or regenerated chitosan films, the method of preparation slightly affected the difference in wettability between the top and bottom of the films, as confirmed by scanning electron microscopy. On the other hand, the wettability of the top and bottom of cellulose films varied greatly depending on the side of the film. Both chitosan and cellulose films had a homogeneous structure. There were differences in the microstructure between the top and the bottom of the sample in the cellulose film, a factor that affected the contact angle and thus the wettability of the surface.

Opis:
This article focuses on preliminary investigations of the manufacture of nonwoven chitosan from a 38-mm chitosan staple fibre and fibres containing silver nanoparticles. The nonwoven chitosan is built of several needle-punched layers of fleece, with a lengthwise arrangement of chitosan fibres. Estimated were mechanical and sorption properties, apparent density, thickness and air permeability of the nonwoven chitosan.

Opis:
Peripheral nerve injuries are one of frequent cause of disability. Results of surgical procedures are not still completely satisfactory, though fast development of microsurgical technician improve their efficiency. One of the major problems in surgical treatment of the peripheral nerve injuries is ends coaptation in the case of large loss of nerve tissue. And so finding substitute implants not rejected by the organism for the recipient and providing with the success is necessary of regeneration. Recently, several synthetic nerve guide implants have been introduced and approved for clinical use to replace autologous transplants. This alternative therapy is based on pioneering studies with experimental nerve guides. This paper present a review of published studies involving biodegradable nerve guides.
