...G. C. Donaldson; D. Robinson; S. L. Allaway 1. Laboratory studies have shown that cold exposure causes an increase in blood pressure, cholesterol and erythrocyte count. However, whether the mild cold exposures received during everyday life are sufficient to cause such changes is unclear. 2. To test...

... arterial thrombosis among elderly people in cold weather. Compared with thermoneutral control experiments, skin temperature (trunk) fell from 35.5 to 29.5°C, with little change in core temperature. 2. Erythrocyte count rose in the cold from 4.29 to 4.69 × 10 12 /l, without a change in mean corpuscular...

..., but there was no increase in either group at 15°C. 3. The association of variables is particularly marked between systolic blood pressure and core temperature changes at 6°C. 4. There were no appreciable cold-adaptive changes in blood pressure or thermoregulatory responses after 7–10 days repeated exposure to 6°C for 4 h...

...Erica K. Potter; Pamela Parker; A. C. Caine; Eugenie R. Lumbers 1. The effect of cold on vagal action at the heart was studied in sheep, dogs and an isolated guinea pig atrial preparation. 2. During cardiac output measurements in un-anaesthetized sheep, by the thermodilution method, bradycardia...

.... It is suggested that an elevation in the set-point temperature for behavioural thermoregulation can occur in some patients with anorexia nervosa, and that this displacement-5-contribute to the distressing sense of cold which some patients experience. 22 7 1981 8 1 1982 © 1982 The Biochemical...

... similar for a given temperature, and lay between the higher values of the male control subjects and the low values of the remaining anorexic patients. 3. Those patients whose vascular responses to cold were exaggerated were characterized clinically by severe and persistent signs of ischaemia...

...J. A. Downey; D. B. Frewin 1. The response of hand blood flow to a measured controlled cold stimulus was determined using venous occlusion plethysmography in normal subjects and patients exhibiting Raynaud's phenomenon. 2. Comparisons of percentage and absolute falls in hand blood flow, and also...
