JOURNAL FREE ACCESSCinchophen sodium administered intravenously to Holtzman rats caused a significant increase in plasma corticosterone concentration, reaching a peak at 30 minutes after injection : a linear log-dose-response curve was obtained between 10 to 40 mg per 100 g body weight of cinchophen and plasma corticosterone level This effect of cinchophen was inhibited by hypophysectomy as well as lesions placed in the median eminence.
Intraperitoneal administration of 0. 5mg of dexamethasone and 5 mg of nembutal per 100 g body weight failed to suppress the effect of 40mg per 100g body weight of cinchophen, in sharp contrast with those of histamine and adrenalin.
It appears reasonable to suggest that the median eminence is involved in a rise in the plasma corticosterone concentration following cinchophen administration.View full abstractDownload PDF (2498K) -

JOURNAL FREE ACCESSA miniature fluoroglass dosimeter has recently been described as a usful and a reliable radiation detector for a variety of clinical dosimetry problems, especially in vivo dosimetry. Its use is based upon the principle of radiophoto luminescence.
Previous to the glass rod dosimetry, the out put of cobalt-60 teletherapy unit is calibrated using a home-made parallel plate ionization chamber with a vibrating reed electrometer.
The glass rod employed is 1 mm, in diameter and 6 mm, in overall length. Some physical characteristics on the dosimeter with respects to the linearity between dose and fluorescence, the fading of fluorescence by rod and the fatigue of a photomultiplier tube and a ultra violet lamp etc, are examined to determine a reliable method for measurements with glass dosimeter.
Gamma-ray dose from cobalt-60 teletherapy unit over the total dose ranges of 100 to 800 R and of 1, 000 to 10, 000R is measured with the glass dosimeter.Ninty-five per cent confidence intervals of the mean of population will be estimated 124 to 128 μA for 100 R exposure and 608 to 628μA for 500 R. Ninty-five per cent confidence intervals of the coefficients of variation will be estimated 3. 8% >σ>1. 8% for 100 R exposure and 4.6>σ >2.1% for 500 R.View full abstractDownload PDF (1072K) -

JOURNAL FREE ACCESSStatic charge produced by friction between the skin and cloth or clothes each other was measured. The matarial was chiefly clothe of textile yarn, it was cut to a test piece 6 × 6 cm and fixed around the edge of a drum. With the test piece fixed on the drum the skin or the cloth was rubbed, and the charge then produced on the test piece was measured. The results were summerized as the following.
1) The static charge produced by friction of the skin with the test material made of textile yarn, the clothes made of which contact with skin in daily life, measured some what largevalue about 10-20 volt with positive or negative sighn.
2) The charge produced by reciprocal friction of the test materials, the clothes made of which does not contact with the skin directly, measured about 20-30 volt, when one of it was textile yarn.
These results were discussed and the conclusion was derived that the charge produced when the clothes was put on wear in daily life was not measured exactly but would not be so large as to affect upon the physical condition even if the clothes would produce static charge of some value when it was weared.View full abstractDownload PDF (3422K) -

JOURNAL FREE ACCESSThe length, weigth, time and temperature were assumed by fifteen girl students (16-17y) and fifteen adult women (20-30y). The average value of differences between the assumed values and the real ones was compared on the studens and women group. The length employed to be measured with eyes was the distance between two points marked with white thread on the cloth hanging vertically at 25 cm distance from the eyes of the subject. In assuming, weigth, a clod of clay containing iron or glass balls (30-100g in total) was employed and clod was took in hand of the subject. To assume time interval 3-9 min, which was sighned by the operator, the subject closed her eyes during the time.
The temperature of the rest of a smoothing iron covered with cloth, which was heated previously at 90-170°C by putting the iron on it. The temperature was assumed by contaction on the surface with a hand.
In these experiment it was resulted that the difference between the assumed value and the real one, i.e. error in average was larger on studens group than on adult women in assumption of length, weigth and time, but no difference in these groups in assumption of the temperature.View full abstractDownload PDF (315K) -

JOURNAL FREE ACCESSThe length of sides of a rectangle marked on the cloth with white thread was measured with eyes. The rectangles were 20, 25 and 30 cm in longitudinal length by 2, 2.5 and 3 cm in side length respectively. The cloth was hanged vertically 25 cm distance in front of the subject siting down on a chair. Thirty girl students (16-17y) and fifteen adult women (20-30y) were employed as the subjects. The half of girl students were naked eyes and the others were cured eyes, the adults were all naked eyes.
Among these groups (a group of naked eyes students, cured eyes student and adult women) the average value of the differences between the assumed length and real one i, e, error in average was compared. It was smaller on the adult group than on the student group of naked eyes, and it was smaller on the group of naked eyes students than on the group of cured eyes ones.
Errors were 10-20% through all the subjects, and the average value of the errors was larger on smaller length than on larger length in every group._View full abstractDownload PDF (295K) -
