Spinal Fluid Driven Artificial Organ
Dr. Ommaya has two children who suffer from Type 1 diabetes. Motivated by his personal experience with the disease, Dr. Ommaya focused on the problem of transplantation of islet cells for the treatment of diabetes. A major challenge facing survival of islet cells is immune rejection. Dr. Ommaya thought that the CSF would provided an ideal setting for transplanted islets due to the immune protection provided by the blood brain barrier. He developed an artificial organ which would house transplanted islets, and the cells could be nourished by the CSF. Ayub, Illani Atwater, and colleagues identified that ventricular-peritoneal CSF shunts provided an immune protected site for the transplantation of mouse and rat islets in dogs and llamas.22, 30 Ayub and colleagues also identified that CSF glucose mirrors blood glucose. Islets cells were able to survive in this system and function in the llama model, but further work on the model is needed.1 Unfortunately Dr. Ommaya was not able to complete this research.

Famous quotes containing the words fluid, driven, artificial and/or organ:
“It is more than likely that the brain itself is, in origin and development, only a sort of great clot of genital fluid held in suspense or reserved.... This hypothesis ... would explain the enormous content of the brain as a maker or presenter of images.”
—Ezra Pound (1885–1972)
“The modern world needs people with a complex identity who are intellectually autonomous and prepared to cope with uncertainty; who are able to tolerate ambiguity and not be driven by fear into a rigid, single-solution approach to problems, who are rational, foresightful and who look for facts; who can draw inferences and can control their behavior in the light of foreseen consequences, who are altruistic and enjoy doing for others, and who understand social forces and trends.”
—Robert Havighurst (20th century)
“Before I finally went into winter quarters in November, I used to resort to the north- east side of Walden, which the sun, reflected from the pitch pine woods and the stony shore, made the fireside of the pond; it is so much pleasanter and wholesomer to be warmed by the sun while you can be, than by an artificial fire. I thus warmed myself by the still glowing embers which the summer, like a departed hunter, had left.”
—Henry David Thoreau (1817–1862)
“But alas! I never could keep a promise. I do not blame myself for this weakness, because the fault must lie in my physical organization. It is likely that such a very liberal amount of space was given to the organ which enables me to make promises, that the organ which should enable me to keep them was crowded out. But I grieve not. I like no half-way things. I had rather have one faculty nobly developed than two faculties of mere ordinary capacity.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
