The authors had described the fine structure of a type of pancreatic islet cell, which appeared different from typical alpha and beta cells, and tentatively considered that this third type of granular cell probably represents the D cell (Figure 1).Since silver staining has been widely used to differentiate different types of pancreatic islet cells by light microscopy, an attempt to examine this staining reaction at the electron microscopic level was made.Material and Method: Surgically removed specimens from three infants who suffered from severe hypoglycemia were used. The specimens were fixed and preserved in 20% neutral formalin. Frozen sections, 30 to 40 micron thick, were prepared and they were stained by Bielschowsky's method as modified by Suzuki (2). The stained sections were examined under a microscope and islet tissues were isolated. They were fixed in 1% osmium tetroxide in phosphate buffer for one hour and embedded in Epon 812 following dehydration through a series of alcohols and propylene oxide.

Glucose Assimilation

ABSTRACT The double intravenous glucose tolerance test does not modify the assimilation coefficient in normal and thin diabetic subjects. On the contrary, in fat diabetic subjects the second coefficient of assimilation increases significantly, but not the first one. From these researches it is evident that the valuation of glucose assimilation by double venous hyperglycaemic test indicates the functional behaviour of the pancreas in different diabetic states. The interpretation of this behaviour of pancreatic islet response to the double venous hyperglycaemic test is discussed.
