[Proteolytic specificity of plasmin with respect to adhesive proteins].

We showed that plasmin specifically hydrolyzes proteins participating in cell adhesion (fibronectin, vitronectin, and laminin) and does not affect nonadhesive proteins, such as albumin, ovalbumin, and alkaline phosphatase. These and some earlier results allow us to speak of the specific antiadhesive activity of plasmin, which significantly extends the concepts regarding the functional importance of this protein and indicates that it directly participates in the regulation of cell adhesion, the remodeling of the extracellular matrix, and, therefore, in cell migration.

[Identification of the protease responsible for the antiadhesive properties of dog blood serum].

The antiadhesive effect of dog blood serum described previously was shown to be associated with the proteolytic activity of the serum components. The protease exhibiting this antiadhesive effect was isolated by several fractionation stages and identified with plasmin.

Non-free osteoplasty of the mandible in maxillofacial gunshot wounds: mandibular reconstruction by compression-osteodistraction.

We have treated 33 young men with medium to large (3-8 cm) bony and soft tissue defects of the lower third of the face caused by gunshot wounds. After debridement, collapsing the proximal segments for primary approximation of soft and hard tissues and a closed osteotomy of a small fragment of mandible, we used an original compression-distraction device, designed in 1982 and tested during 1983 (analogous devices were absent at that time) to reposition the mandible and cause callus to form (during distraction) between the fragment and to use the remaining stumps of bone to fill in the defect. The soft tissues were repaired at the same time.
