In this report, the following subjects were studied on dynamite plant workers :
1. The cardiovascular response to nitroglycerine (NG) of the worker.
2. Follow-up studies of the cardiovascular responses to NG of newly employed packers.
3. Difference in the cardiovascular responses to NG of the worker between Saturday and Monday morning.
4. Differences of the autonomic nervous activities of the worker between Saturday and Monday morning.
And the following results were obtained :
1. The cardiovascular responses to NG of the worker were less than those of the control.
2. The responses to NG of the newly employed packer showed a tendency to decrease with longer duration of employment in the dynamite plant.
3. In general, the cardiovascular responses to NG of the worker on Monday morning were greater than those taken on Saturday morning in comparison with the control.
4. There was no difference in autonomic nervous activities of the worker between Saturday and Monday morning.
5. The lowered susceptibility to NG of the worker was acquired not only in the feeling of headache but also in the cardiovascular system.
6. The influences of nitroglycol and nitroglycerine to the worker were classified into three types.
