Pathological Studies on Effects of Vitamin E : (II)EFFECTS OF VITAMIN E ON GROWTH OF RATS

Comparison was made on the growth rates of Wistar strain male rats fed on vitamin E-deficient diet and on vitamin E-excessive diet for 9 months since weanling. Since both the increase in stature and the stimulation of retraction of thymus were observed in the vitamin E-excessive group, an indispensable function of vitamin E for growth and development of rats was presumed. From these results and observations, the biological significance of vitamin E would be deduced that the vitamin might be essential for mitosys and maintainance of cellular function besides the well-known vitamin action.

The Determination of Blood 2,3-Diketogulonic acid by 2,3-Dimercaptopropanol-2,4-dinitrophenylhydrazine Method

The fractional determination of L-dehydroascorbic (DAsA) and 2,3-diketogulonic acid (DKG) by the 2,3-dimercaptopropanol (PSH)-2,4-dinitrophenylhydrazine (DNP) method was investigated. DAsA, which reacts with DNP to produce hydrazone as well as DKG, is reduced to ascorbic acid by PSH. Excess of PSH is removed with N-ethylmaleimide, to prevent turbidity. Then DKG is incubated with DNP at 37℃ for 3 hours to make the hydrazone.

In the UV irradiation of 7-dehydrocholesterol, the effect of wavelength on the formation of vitamin D_3 and other isomers was investigated and the results were compared with those on the UV irradiation of ergosterol reported previously^<1)>. The irradiation was carried out by monochromatic UV lights obtained from a spectroirradiator and the yield of vitamin D_3 was estimated by gas liquid chromatography as described previously^<2)>. When a 7-dehydrocholesterol solution in ethanol (1.0mg/ml) was irradiated by monochromatic UV lights in the range 230〜350nm with the quantum energy of 4.0×10^8 erg/cm^2,the figure of the relationship between yield of vitamin D_3 and wavelengths of irradiating UV lights showed a mountain shape with a peak at 295nm. The results were nearly identical with that of ergosterol and moreover there were little differences between the patterns of gas chromatograms of 7-dehydrocholesterol and ergosterol irradiated by the corresponding UV light. It was concluded from these results that the two types of provitamin D must show the same attitude to UV irradiation.
