  • Values are means ± SE for 7 or 8 experiments. Shown are blood flow values for the duodenum, ileum, colon, and adrenals during normothermia (37.5°C) or hypothermia (28°C) in animals pretreated with an intravenous injection of either saline, atropine, hexamethonium, propranolol, or yohimbine or surgical subdiaphragmatic vagotomy.

  • * P < 0.05 compared with saline-treated hypothermic controls.
