[Applied anatomy of the distal "vinculum tendinis" in the fetlock tendon sheath of the hindlimb in cattle].

A relatively thick (diameter approximately 2 mm), ropelike (length ca. 20 mm) and elastic "Vinculum tendinis" connects--within the fetlock tendon sheath--the dorsal side of the deep digital flexor tendon with the dorsal part of the Manica flexoria (the communicating band of the Musculus interosseous medius to the superficial digital flexor tendon). The extensive fetlock tendon sheath can be involved in diseases such as aseptic and septic inflammations. Spreading of these inflammations makes in some of these cases the partial resection of the tendon of the deep digital flexor muscle and the cutting of these Vincula necessary. The results of this contribution, collected from 60 hindlimbs of adult bovines show variations in number, length, diameter and extent and the inner structure with blood vessels and nerves.

Use of a vascular skeletal muscle graft for canine esophageal reconstruction.

A technique for reconstruction of the thoracic esophagus was evaluated in 13 dogs. A 9 x 10 cm section of transversus abdominis muscle was harvested, fashioned into a tubular graft, and vascularized via the greater omentum. The vascularized tube was advanced into the caudal thorax through the diaphragm at a second surgery 20 to 44 days after harvesting the section of the transversus abdominis muscle. A 5 cm section of caudal thoracic esophagus was replaced with the vascular tubular graft. One dog died because of incarceration of the intestine within the tube and two dogs were euthanized because of infected tubes. One dog died due to an anesthetic complication, one dog had a diaphragmatic hernia and died, and one dog died from pyothorax. Leakage of luminal contents at the anastomoses did not occur in any dog. Seven dogs survived both surgeries but showed deglutitory difficulty 6 days postoperatively due to the grafted esophageal segments becoming severely strictured in each case. Angiography demonstrated vascularization of the full thickness of the graft in each of the seven dogs. An unacceptably high incidence of infection and stricture formation made this technique unsuitable for clinical use.

The method of multilayer gel plates for the analytical immunochemical techniques.

A new analytical immunochemical method using gel film copies obtained by means of multilayer gel plates is described. The method is suitable for any variant of immunochemical gel technique. Perfect identity of the copies as well as some advantages are exemplified. In comparison with the already known monolayer gel plate method, the multilayer plate is more advantageous for the study of the dynamics of the antigen-antibody reaction, for the discovery of the nature of some unknown biological products available in very low quantities and for the discovery of the nature of some unknown biological products available in very low quantities and for the economy of certain costly reagents. Moreover, its high reproductibility recommends it as a reference method for the control of quality, especially of the precision and accuracy of the monolayer immunofiltration techniques.
