Abstract
Summary
Comparative studies on liver blood flow, oxygen consumption, liver and rectal temperatures, oxygen of liver were conducted on cold-adapted and warm-adapted rats. Muscular activity of all rats was blocked by curare. Liver blood flow was measured by blood clearance curve of radioactive chromic phosphate injected intravenously No difference in temperature between rectum and liver was found in a given rat in both groups. Liver blood flow in cold-adapted rats did not differ from that of warm-adapted ones so long as tests were performed in a warm room (30°C). However, liver blood flow in cold-adapted rats was considerably greater than that of warm-adapted ones when animals were cooled, though not sufficient to account for the excess oxygen consumption.
