Nine South African Negroes with abdominal aortic aneurysms due to intimomedial mucoid degeneration are described. These occurred in a younger age group than atherosclerotic aneurysms and with a female predominance. The aneurysms are not syphilitic in origin and are unlike atherosclerotic aneurysms. This form of abdominal aneurysm constitutes a distinct entity which is relatively prevalent in South African Negroes and which has hitherto received little or no emphasis and attention.

It has been shown previously that, at least in dogs, a vascularized pancreatic allograft with ligation of the pancreatic duct can maintain normal beta-cell function for at least 5 years. In this study common organ preservation techniques, as used in human cadaveric kidney transplantation, were applied to canine pancreatic allografts to determine the influence of 24-hour preservation on beta-cell function, graft survival and histological appearances. ⋯ It appeared that both preservation methods were equally effective and that preservation did not alter either the graft's function or its histological appearance. No significant differences after transplantation were observed in the endocrine function tests of the three groups when compared with the preoperative values; neither was there a significant difference in the mean graft survival time between the groups.
