Abstract : Dogs were held for several days at 1 - 5C. Some dogs had the hair clipped off; others had a full pelt. Adrenals were removed and stained to demonstrate lipid. Control dogs had most adrenal lipid; cold-exposed, clipped dogs had less; cold-exposed dogs with normal pelts had least adrenal cortical lipid. The clipped dogs survived for only three days in cold; the unclipped for at least seven days. Cold exposure induced a loss of adrenal cortical lipid -- a sign of elevated cortical secretory activity. Cold plus clipping overwhelmed the subject dogs and prevented maximal adrenal secretory response -- a situation reflected in the shorter survival of the clipped dogs in the cold. (Author)
