A simple test was devised to identify people susceptible to chlorpropamide-alcohol flushing (CPAF). Subjects were given a placebo tablet, followed by sherry 12 and 36 hours later. They then received a chlorpropamide tablet and sherry again after 12 and 36 hours. This single-dose challenge test was given to non-insulin-dependent diabetics, insulin-dependent(More)
Non-insulin-dependent diabetes is associated with facial flushing after alcohol in patients on chlorpropamide (chlorpropamide alcohol flushing, C.P.A.F.) especially when there is a family history of diabetes. C.P.A.F. in three subjects (two diabetics, one non-diabetic) was blocked by the specific opiate antagonist naloxone. In nine subjects (six diabetics)(More)
Expression of HLA DR antigens on T lymphocytes indicates that these cells are actively involved in an immune response. Raised levels of activated T lymphocytes were found in 14 of 15 recently diagnosed but in only 7 of 28 long-standing insulin-dependent diabetics. 9 of the recently diagnosed patients retested 6 months later still had high levels of(More)
The single-challenge test for chlorpropamide-alcohol flushing (CPAF) was used to study two groups of patients with non-insulin-dependent diabetes and a family history of the disease who were distinguished only by their age at diagnosis (under and over 30). Their relatives were also studied. The proportions of patients showing CPAF in both groups were(More)
Demographic characteristics associated with the maintenance and growth of populations, such as seed dynamics, seedling emergence, survival, and tiller dynamics were examined for two tussock grasses, the native Agropyron spicatum and the introduced Agropyron desertorum in a 30-month field study. The introduced grass was aerially sown onto a native grassland(More)
The prevalence and features of diabetic retinopathy have been examined in 95 pairs of identical twins, 31 concordant for insulin-dependent diabetes (IDD), 27 discordant for IDD, and 37 concordant for non-insulin-dependent diabetes (NIDD). Optic fundi were examined after pupillary dilatation and retinopathy was classified as nil, background, or severe. In(More)
Thirty-eight patients in diabetic coma from four different centres were treated with a continuous low-dose intravenous infusion of insulin at an average dose of 7.2 IU/hr. All patients recovered rapidly except for one profoundly shocked patient who died. The mean fall in plasma glucose was 58% four hours after the start of insulin. Blood ketone bodies and(More)
