We microneurographically recorded the traffic of sympathetic nerves leading to foot volar skin activity (SSA) and leg skeletal muscle activity (MSA) during isometric handgrip and simultaneously determined sweat rate by the ventilated capsule method and skin blood flow by laser-Doppler flowmetry in the innervating area of SSA. SSA increased abruptly and was almost constant during handgrip, accompanied by an increase in sweat rate, whereas skin blood flow showed no significant change during the handgrip. MSA showed a time-dependent increase during the course of handgrip. During arterial occlusion of the working forearm after handgrip, SSA decayed to the precontraction control level, whereas MSA remained at a higher level than during control. During involuntary biceps muscle contraction induced by electrical stimulation, both SSA and MSA increased. The results suggest that the SSA response during voluntary handgrip, which was demonstrated to contain mainly sudomotor activity, might be influenced by central command and input from peripheral mechanoreceptors but be influenced little by input from muscle chemoreceptors.

The Hanshin-Awaji earthquake in January 1995 caused the greatest number of deaths and injuries in Japan since World War II. Various weaknesses of modern information systems were exposed during and after the earthquake. The authors carried out a questionnaire survey to investigate the current state of hospital information and to examine the kinds of information needed immediately after an earthquake. The survey results show that information about the ability to admit new patients and the availability of medical supplies is necessary immediately after such a disaster. These results will be useful for planning countermeasures against this kind of disaster.

As the hospital doctor shortage in rural areas becomes more serious, exploring doctors' desire to leave their current hospital is meaningful for Japanese hospital managers and hospitals worldwide aiming to provide sustainable and higher quality care.
