RESUMEN
Objective To study the effect of the magnetic field-treated water on metabolism of monoaminergic nerve transmitters in mice. Methods Twenty healthy aged Kunming mice were divided into a control group and an experimental group randomly. The mice in the control group were given tap-water and those in the experimental group magnetic field-treated water for 30 days. The content of monoaminergic nerve transmitters in brain of mice in the two groups were determined. Results A significant difference was found in the content of monoaminergic nerve transmitters between the control and the experimental groups. The contents of NE, DA, 5-HT and 5-HIAA increased significantly(P
RESUMEN
Based on sciences of medicine, electronics and computer, this paper details such information of the portable monitor of HRV as the designing principles and essentials of the software and hardware designs. The monitor has a lot of virtues including being lightweight, integrative, visual and controllable. It can not only suit the test of physical and mental work intensity but also offer important HRV parameter for clinical diagnoses of cardiocerebral vascular diseases. It can also be used by individuals, families and service stations.
