Acetabular posterior wall fracture. 38 cases followed for 5 years.

Thirty-eight patients with a fracture of the posterior wall of the acetabulum were reviewed after 5 (2-12) years. Of 18 patients with successful manual reduction of a femoral head dislocation, a small fracture fragment, no sciatic nerve injury and who were not operated on, 17 had a good result. Of 20 patients who were operated on either because of the large size of the fracture fragment or because of a persistent dislocation of the femoral head, 6 had a poor result due to femoral head necrosis.

Canine gastric glycoprotein antigens in early carcinogenesis.

The effect of one single dose of N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) on the antigenic structures of gastric juice glycoproteins, was studied in dogs. Antisera to glycoproteins of the fetal alimentary canal were raised. Histologic mucosal specimens and glycoprotein fractions of gastric juice which were taken from four dogs during a 15.

Hand injuries in Finland.

The study is based on patients with hand injuries treated in the casualty department of Turku University Central Hospital during the years 1971-75 and 1978; there were 4 800 of these patients annually. Hand injuries accounted for 26% of all accidents. Of these patients, 14% were younger than 15, 78% were of working age and only 8% were over 65.

Acute effects of burn injury on tissue gas tensions in the rabbit.

Early effects of 10% full-thickness skin burn on subcutaneous tissue PO2 and PCO2 levels were studied in anesthetized rabbits. Tissue gas tensions were determined by means of implanted Silastic tonometers in two different areas in each animal--the burn site itself, and an area remote from the injured tissue. Thermal injury resulted in a rapid, progressive decrease of the tissue PO2 in both locations, with the greatest decrease at the burn site.
