The effects of 17-beta-oestradiol (E2) and progesterone (P) on insulin sensitivity were determined in oophorectomized (OVX) rats by the euglycaemic hyperinsulinaemic clamp technique combined with measurements of insulin-stimulated 2-deoxy-D-glucose (2-DOG) transport and glycogen synthesis in white and red parts of the gastrocnemius, the extensor digitorum(More)
A patient with a somatostatin (SRIH)-secreting islet cell tumor, whose only symptoms were dyspepsia and anemia, is described. The diagnosis of somatostatinoma was based on high plasma SRIH concentrations and immunocytochemical findings. The pancreatic exocrine response to secretin was decreased, whereas the insulin and/or glucagon responses to glucose and(More)
