| Abstract: | Plasma from BALB/c mice bled 90 minutes after allogeneic lymphocyte injection significantly rises glucose induced insulin secretion. This rise is observed in pancreas either from non-treated or from allogeneized mice. This rise is time and dose-dependent. An 1/40 dilution is enough to bring about a significant increase on insulin secretion. This effect is seen when mice are bled between 60 and 180 minutes after injection with a maximum effect at 90-120 minutes. Plasma from BALB/c mice injected with C57BL/6 J lymphocytes rises insulin secretion from BALB/c, C57BL/6 J, C3h and C57BL/KsJ mice pancreas. Plasma from streptozotocin diabetic BALB/c mice and from genetically diabetic C57BL/KsJ mdb-mdb mice injected with allogeneic lymphocytes stimulates glucose induced insulin secretion but to a lesser extent than plasma from normal non-diabetic mice does. |
