[Changes of locomotor activities, lipid peroxide levels and their related enzyme activities in rat loaded with swimming exercise (author's transl)].

The changes of locomotor activities in rat loaded with swimming exercise were recorded by our newly devised apparatus. In addition, changes of lipid peroxide levels and their related enzyme activities in rat brain, liver as well as blood were studied. The results obtained were as follows: 1.

[Studies on the items for diagnosis of the vibration disease. Part 1. Examination of healthy workers using vibratory tools].

1,215 male workers using bush cleaners in Hokkaido were examined by the method based on the notification of the Labor Standard Bureau. The results obtained from clinically normal 548 workers among them were analysed especially on the finger skin temperature, vibratory sense threshold, maximum grip strength. 1) Data of the vibratory sense threshold, maximum grip strength and endurable grip strength showed normal distributions.

[Studies on the change of spontaneous locomotor activities in rats due to forced exercise (author's transl)].

The authors have devised an apparatus for monitoring the spontaneous locomotor activity of rats, with which the patterns of locomotor activity under the condition of light-dark cycle (light period: twelve hours from 6 a.m., dark period: the other half of the day) were analysed.
