A collagen film for microdetermination of collagenase activity.

A simple, rapid, sensitive, and specific film assay for collagenase activity employing a glass-supported, reconstituted collagen gel is described. Digestion of the collagen film results in sharply defined zones of lysis detectable by staining with Coomassie blue. The assay is semiquantitative and suitable for micro enzyme determination in biological fluids.

Human hypoxanthine-guanine phosphoribosyltransferase. Steady state kinetics of the forward and reverse reactions.

A steady state kinetic study of the hypoxanthine-guanine phosphoribosyltransferase-catalyzed reaction in the forward and the reverse directions was carried out. The results obtained favor a sequential mechanism where the monomagnesium complexes of IMP and PPi bind to the enzyme in a rapid equilibrium random fashion while products must dissociate from the enzyme in ordered sequence, first the purine base and then the magnesium complex(es) of P-Rib-PP.

Autologous blood pre-deposit in cemented hip arthroplasty.

The authors examine one of the methods used to avoid homologous blood transfusion in patients submitted to cemented hip arthroplasty. Although the series is not a numerous one (25 cases) it does show that even the pre-deposit of single unit of autologous blood is capable of eliminating the need for homologous blood transfusion in 96% of all cases.

The gamma nail and the compression-sliding plate in the treatment of pertrochanteric fractures: anesthesiologic aspects.

The authors compare the results obtained in a group of 100 patients submitted to pertrochanteric osteosynthesis during the year 1991 (50 with a gamma nail and 50 with a compression-sliding plate) based on parameters of anesthesiology. The same type of anesthesiology was used in all 100 of the patients, as similar were the general clinical conditions of the patients, ASA classification, and the mean value of preoperative hemoglobin. The gamma nail proved to be preferable in terms of a shorter amount of time required for surgery, a minor loss of blood intra and postoperatively, and minor incidence of complications.
