Bilateral retinal vascular occlusions occurred simultaneously in a 25-year-old man. They were treated by exchange transfusions. After the transfusions, the patency of the previously occluded vessels was reestablished. Subsequently, the patient recovered good central vision. It is interesting to speculate how exchange transfusions, used during the past few years for treatment of life-threatening situations, may be useful for the treatment of retinal arterial occlusions in patients with sickle cell disease.

Reversal of diabetes in rats using fetal pancreases stored at -196 C.

Fetal rat pancreases frozen to and stored at -196 C were used for transplantation into streptozotocin-induced diabetic syngeneic adult recipients. Transplantation was carried out either directly after thawing from -196 C, or after a 21-day growth period in a syngeneic, normoglycemic adult carrier. All transplants were placed under the kidney capsule. A single, frozen fetal rudiment was sufficient to restore blood glucose, urine volume, and urine glucose to normal, provided it had first been grown for 21 days in a normal carrier. It vitro perfusion studies showed that fetal pancreases stored at -196 C were equivalent to fresh rudiments in their responses to a glucose stimulus.
