Abstract
Summary
Distribution of D-xylose in the uncut rat diaphragm was studied in vitro under a variety of conditions. It was found that epinephrine, triiodothyronine or Cortisol had no effect on distribution of this sugar when administered in vitro. Triiodothyronine or Cortisol, administered parenterally, increased the space occupied by D-xylose in absence of insulin, and in presence of insulin it resulted in comparatively small but consistent addition to the space occupied when insulin alone was used. A 24-hour starvation period was without effect on sugar distribution whereas a 56-hour period increased the xylose space in absence of insulin and was quantitatively additive in its presence.
