Rigid stability has long been the accepted major principle for treatment of non-union of shaft fractures (MUller, Allgower and Willenegger 1965; B#{246}hler1966; MUller 1966; KUntscher 1967). Until recently, methods of gaining stability have usually combined internal fixation by osteosyntheses and external fixation by plaster or traction (Boyd, Anderson and(More)
Angiotensin II is synthesized locally in various tissues; however, the role of interstitial angiotensin II in the regulation of regional metabolism and tissue perfusion is not clear. We characterized the effect of interstially applied angiotensin II in skeletal muscle and subcutaneous adipose tissue of young, normal-weight, healthy subjects by using the(More)
From 1980 to 1989, 575 unicompartmental prostheses were implanted for gonarthrosis in 415 patients. More than half of the prostheses were operated in cases of arthrosis of both knees. In 115 patients, both knees were operated on the same day. Pain relief was very good, and the patients were generally satisfied. There was no loss in follow-up evaluation,(More)
Twenty cases of nonunion of forearm fractures were treated by the Küntscher method of intramedullary reaming and nailing. Fifteen fractures healed per primam; 2 required renailing; 2 did not heal but the patients benefited from the stabilizing effect of the nail; 1 was lost to follow-up. Even infected cases could be treated successfully by this method, but(More)
Thirteen cases of nonunion of the humerus were treated by intramedullary reaming and nail fixation. Rigid stabilization which was usual after operating upon other long bones was not always secured in these cases, and supplementary plaster immobilization was necessary. Seven fractures healed and 3 fractures required re-nailing before healing. Three fractures(More)
Human fetal pancreatic explants were maintained in organ culture for up to 12 days in medium TC 199 or RPMI 1640 supplemented with 20% fetal calf serum. The explants were cultured at their air-liquid interface on a Millipore filter supported by surgical gel foam (ALI technique). The insulin accumulation in the culture medium decreased considerably when(More)
A case of a Sertoli cell tumour in one testis of an 111/2-year-old bull of the Red Danish breed is described. Ipsilaterally segmental aplasia of the Wolffian duct practically with aplasia of the epididymis occurred. The bull had served normally in an AI society until at the age of 11 years he acquired impaired semen quality. The tumour showed both a diffuse(More)
