The relationship of local skin temperature and the onset of sweating to the local cutaneous blood flow was studied in the forearm and calf. The purpose of the investigation was to appraise the possible relation of sweat gland activity to the cutaneous vasodilatation which has been attributed to bradykinin or to intracranial temperatures. The onset of sweating was not marked by any apparently related increases in the rate of cutaneous blood flow. On the contrary, the onset of sweating was followed often by a stabilization or even a decrease in the level of cutaneous blood flow. The relations of the latter to the local skin temperature were complex, particularly in the forearm. There appeared to be additional unidentified influences, possibly vasomotor, operating on the skin vessels during transitional phases in the relation of skin temperature to blood flow.

Fractional Distribution

To determine the relationship between mammary and cutaneous blood flow (BF) the regional distribution of 86RbCl was used to estimate the fractional distribution of the cardiac output to these tissues in virgin, multiparous, pregnant and lactating mice. The results indicate a positive linear correlation between the values obtained for the skin and that obtained for its underlying mammary tissue. This finding may have a practical application, since the skin is more readily accessible for BF measurements than the mammary tissue that it covers.

1. The effects of locally induced alterations in skin temperature on the postural changes in skin blood flow of the foot were assessed in 38 healthy subjects in a constant-temperature environment (22 ± 0.5°C, mean ± sd). 2. Moderate local cooling and warming of the foot (26–36°C) was induced by blowing cold or hot air. Higher ranges of temperature (38–44°C) were achieved by a thermostatically controlled disc heater. 3. Skin blood flow was measured before and during each change in local skin temperature using a laser Doppler flowmeter with the foot maintained at heart level, and placed passively 50 cm below the heart. Blood flow was measured in two skin areas: (i) the dorsum of the foot, where arteriovenous anastomoses are absent, and (ii) the pulp of the big toe, where these anastomoses are relatively numerous. 4. It was found that within the physiological temperature range of 26–36°C the normal postural fall in foot skin blood flow was preserved, whereas it was markedly attenuated or totally abolished at higher temperatures (38–44°C). The pattern of response was quite similar in areas having or lacking arteriovenous anastomoses. 5. It is suggested that the failure of postural vasoconstriction observed at the higher skin temperatures might contribute to some of the problems of cardiovascular adaptations seen in a hot environment.

The vascular response to local skin cooling is dependent in part on a cold-induced translocation of α2C-receptors and an increased α-adrenoreceptor function. To discover whether β-adrenergic function might contribute, we examined whether β-receptor sensitivity to the β-agonist isoproterenol was affected by local skin temperature. In seven healthy volunteers, skin blood flow was measured from the forearm by laser-Doppler flowmetry and blood pressure was measured by finger photoplethysmography. Data were expressed as cutaneous vascular conductance (CVC; laser-Doppler flux/mean arterial blood pressure). Pharmacological agents were administered via intradermal microdialysis. We prepared four skin sites: one site was maintained at a thermoneutral temperature of 34°C (32 ± 10%CVCmax) one site was heated to 39°C (38 ± 11%CVCmax); and two sites were cooled, one to 29°C (22 ± 7%CVCmax) and the other 24°C (16 ± 4%CVCmax). After 20 min at these temperatures to allow stabilization of skin blood flow, isoproterenol was perfused in concentrations of 10, 30, 100, and 300 μM. Each concentration was perfused for 15 min. Relative to the CVC responses to isoproterenol at the thermoneutral skin temperature (34°C) (+21 ± 10%max), low skin temperatures reduced (at 29°C) (+17 ± 6%max) or abolished (at 24°C) (+1 ± 5%max) the vasodilator response, and warm (39°C) skin temperatures enhanced the vasodilator response (+40 ± 9%max) to isoproterenol. These data indicate that β-adrenergic function was influenced by local skin temperature. This finding raises the possibility that a part of the vasoconstrictor response to direct skin cooling could include reduced background β-receptor mediated vasodilation.
