説明

The humidity of finger pulp were examined 5 times at an hour intervals with 29 healthy male adults and 10 male forestry workers, who had past history of Raynaud's phenomenon but had not developed it for the last 6 months or more (here after referred to as Raynaud subject).The examination was performed at a room temperature of 20-22°C, and the examined items were the impression of finger's humidity, skin electric resistance, and the printing on the perspiration paper.<BR>The chief findings were as follows :<BR>1) In each individual, the humidity of the finger pup is neither constant, nor varying markedly. A greater number of Raynaud subjects give visual impression of “dried hand” than healthy subjects.<BR>2) As for skin electric resistance, healthy subjects more frequently give medium values, whereas Raynaud subjects give higher values at greater percentage.<BR>3) In perspiration test, healthy subjects infrequently make faint printing on the perspiration paper, whereas Raynaud subjects usually make faint printing.<BR>4) Observation on skin electric resistance and perspiration in the course of time can differentiate unstable type showing large diurnal variation from stable type showing small variation. Those giving the impression of “wet hand” are stable both in skin electric resistance and perspiration tests, giving deep printing on the perspiration paper. Those giving the impression of “dry hand” are unstable in both tests.<BR>5) As for the relation between plethysmogram, finger's skin temperature and skin color, which were all investigated by the author's collaborators, and impression of finger's humidity, those giving the impression of “wet hand” generally show large wave height in plethysmography, while those giving the impression of “dry hand” show small wave height. No evident relation is seen between finger's skin temperature or skin color and the impression of finger's humidity.<BR>6) Among healthy subjects are also found characteristic features of Raynaud's subjects, that io the impression of “dry hand”, lowered perspiration and unstable skin electric resistance. Those having these features are considered as “risk group”, since they may have predisposition for Raynaud's phenomenon.
