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.
Exposure duration: repeated daily exposure, 15 min/day for 6 days
|Exposure duration||repeated daily exposure, 15 min/day for 6 days|
No parameters are specified for this exposure.
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).
