Abstract
Provided is a new means for suppressing inflammation or suppressing inflammatory cytokine production. Provided is a device in which a weak pulse current is passed through a living body or living tissue to suppress inflammation in the living body or the living tissue. This device is provided with a power supply means, and a current control means for receiving a supply of power to intermittently apply a direct current at prescribed intervals, and is configured such that the current control means includes a pulse width modulation control means, and the pulse width modulation control means generates a pulse wave that is a rectangular wave, and in which the time indicating a peak value for rising in one cycle of the pulse wave (“pulse duration”) is at least 0.1 millisecond, the peak value is 1.0-20 V, inclusive, and the duty ratio of the pulse wave is at least 5.5%.
