RP610 hemofilters have been used up to five times in post-dilutional hemofiltration. Clearance studies were performed "in vivo" (creatinine and phosphate) and "in vitro" (Cr51 EDTA, I131 Hypaque, Co57 vitamin B12, H3 Inulin, C14 Dextran, I125 Albumin,) in new hemofilters and in those re-used once and five times. Hydraulic permeability and rejection coefficients, for the six markers different molecular weight, were also measured. Our preliminary results show that repeated cleansing with Amuchina does not alter the characteristics of RP610 hemofilters. A scintigraphic method is suggested for visualizing possible changes in polarized areas between new and re-used hemofilters.

D011877 Radionuclide Imaging The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D006438 Hemodilution Reduction of blood viscosity usually by the addition of cell free solutions. Used clinically (1) in states of impaired microcirculation, (2) for replacement of intraoperative blood loss without homologous blood transfusion, and (3) in cardiopulmonary bypass and hypothermia.

D013667 Technetium The first artificially produced element and a radioactive fission product of URANIUM. Technetium has the atomic symbol Tc, and atomic number 43. All technetium isotopes are radioactive. Technetium 99m (m Technetium 99m,99m, Technetium
D014462 Ultrafiltration The separation of particles from a suspension by passage through a filter with very fine pores. In ultrafiltration the separation is accomplished by convective transport; in DIALYSIS separation relies instead upon differential diffusion. Ultrafiltration occurs naturally and is a laboratory procedure. Artificial ultrafiltration of the blood is referred to as HEMOFILTRATION or HEMODIAFILTRATION (if combined with HEMODIALYSIS).
