Variance analysis of the effects of simulant magnetic field, high-temperature and noisy enviroment on ships / 解放军医学杂志

ABSTRACT

Objective To investigate the characteristics of interactive effects of magnetic field of two intensities combined with high-temperature and noise simulating ship environment. Methods Orthogonal trial design of three factors and two levels and variance analysis method were employed. The rabbits and rats were grouped into eight combined exposure groups and eight controls, respectively, according to orthogonal table L_8 (2~7). Animals in all groups underwent the experiments and the indices were determined at the same time. Results Analysis of the radius of capillary vessels on rabbit's conjunctiva and HSP70 of rat's liver and spleen showed that magnetic field was the dominant factor (P
