PTP1B and TC-PTP: novel roles in immune-cell signaling.

abstract：:Radioactively labelled microspheres (15 micron diameter) were used to measure cardiac output (CO) distribution and blood flows in spleen, kidneys, and skeletal muscle before and after normovolemic anemia or polycythemia in anesthetized rats. Hematocrits were changed from 45 to 33% or from 45 to 59% by an exchange tran...
