[Methods for the preservation of soft tissue preparations for clinical use].

The demand for consistent supply of nonvital allogenous implants in tissue banks has the supposition for graft preservation. Besides of many logistic advantages the preservation methods are accompanied by the influence of original attributes, especially of biomechanic parameters in soft tissue preparations. A procedure of dura mater preparation, of fascia lata, tendons and skin is demonstrated which is preserving the required qualities of plasticity, softness and resistance.

[The adhesive strength of tissue adhesives].

Twenty concentrates were produced of the blood from voluntary healthy donors by a method for producing autologous tissue adhesive. Their adhesive strength were tested by means of Thermo-fleece-specimens. A review was elaborated about the kinetics and the testing of the fibrin fixation.

[Allogenic lung transplantations following pretreatment of recipients with donor-specific splenic antigens].

Lung transplantations were carried out in 20 not immunologically selected mongrel dogs which were pretreated with donor specific spleno-antigen mixture. The average survival time was double the size (12.3 days) as in a control group of untreated dogs after allogenic lung transplantation.
