The experiments were performed to observe the effects of drinking alcohol on physiological, sensory and motor functions connecting with automobile driving. The changes in performances with 5 different types of instruments commonly used for driving aptitude test, were examined besides physiological functions such as pulse-rate, blood pressure, body temperature and grasping power. Each subject was tested before the drinking and at 30 min, 2 hr, 4 hr and 5 hr after drinking Japanese rice wine, "sake", which contains 16% (v/v) alcohol. Each test was performed in one control group and three drinking groups of different alcohol dose. The significant increase in pulse-rate was observed in the group of the highest dose of alcohol (10 ml/kg) after 30 min and 2 hr of drinking. Regarding blood pressure, the maximum blood pressure significantly decreased after 2, 4 and 5 hr both in 6 ml/kg and 10 ml/kg group and, on the other hand, the significant decrease of the minimum pressure was only observed after 30 min in 10 ml/kg group. The body temperature significantly decreased after 30 min and 2 hr of drinking the highest dose. Also in the 10 ml/kg group, the significant decrease in grasping power was observed after 30 min and 2 hr of drinking. The response to visual stimuli was significantly affected at the early phase after drinking higher dose of alcohol. In addition, the ability to respond to the stimulus seems to be much lowered by alcohol because in this test the one must concentrate on the visual stimulus for longer time. (Author/TRRL)
