説明

We investigated the cold reaction of fingers in cold water as a criterion of peripheral resistance to frostbite in order to obtain elementary data to improve farmers' health. Experiments were carried out on 81 farmers and 64 urbanites at 20±2°C, 55±5% RH with sitting position on the floor. The finger skin temperatures of the subjects were measured while the left middle finger of each subject was immersed in cold water or 0°C for 30 minutes and recorded once every one minute with the thermistor. We also compiled statistics on the following items: mean finger skin temperature (MST), finger skin temperature at initial rising after immersion (TFR), time for the appearance of initial rising after immersion (TTR), cold resistance index (RI), etc. The results were as follows RI was higher in farmers than in urbanites, but there was no significant difference between the two groups. In men, RI was lower in farmers than in urbanites, but there was no significant difference between the two groups. By contrast, in women, TFR and RI were significantly higher in farmers than in urbanites. MST was significantly higer in women than in men, but RI was no statistically significant difference. By age, the men in their 30's showed significantly the highest MST and the shortest TFR. RI was significantly higher in the men in their 30's than others. In women, however, the difference in RI was of no statistical significance. By region, MST was the highest in Seoul dwellers. RI was the highest in Okku dwellers, but there was no statistically significant difference among regions.<BR>These results indicated that farmers tended to be higher than urbanites in cold resistance index.
