研究目的(著者による)

To study the relationship between changes in proteolytic activity of pepsin and morphological characteristics of the gastric mucosa produced by nonthermal electromagnetic fields with the plane of polarization rotating in either right-handed or left-handed sense.

General information

Rats were divided into 3 groups (n=10 per group); group 1 was used as control, group 2 and group 3 were exposed to D-polarization and L-polarization respectively.

研究の主なアウトカム(著者による)

D-polarization (right-handed) increased digestive activity of pepsin in relation to blood plasma proteins and hemoglobin. L-polarization (left-handed) suppressed pepsin production.
Morphological examination revealed progressive hypertrophy of glands and chief cells on days 1-6 of exposure to D-electromagnetic fields. These changes reflected high-intensity secretion of pepsin and HCl. L-electromagnetic irradiation induced morphological changes in the gastric mucosa (progressive necrobiotic changes).
