- Fig. 1 is a photograph showing the results of a skin irritation preventive effect test using erythema as an index.
- Application of 10% sodium lauryl sulfate ointment 2 6 hours after guinea pig skin application 1% This shows the difference in the degree of erythema between the application site of this compound ointment (left side) and the application site of white petrolatum (right side).
- Table 1 shows the results of a skin irritation preventive effect test using erythema as an index.
- Figure 1 is a photograph showing the difference in the degree of erythema between the application site of 1% compound ointment and the application site of white agate cerium 26 hours after application of 10% sodium lauryl sulfate ointment. The From this photograph, it can be seen that the erythema is more marked on the white petrolatum application site (right side) than on the application site (left side) of the 1% compound ointment.
- the average value in the table is the average value of 4 cases in each group. The lower the erythema score, the greater the preventive effect on skin irritation.
- the flank of the guinea pig (Hartley) is shaved to form two application sites per animal, and an irritating substance, 10% sodium lauryl sulfate sulfate ointment, is applied to each application site. Open application. The next day, white petrolatum was applied to one side and 1% of the compound ointment (1% of the compound + 99% white petrolatum) was applied to the other side twice a day.

- Table 3 shows the results of the skin irritation improvement test using epidermis peeling as an index.
- the frequency of occurrence in the table is the result of 4 cases per group.
- Dermatitis was induced once a week (Tuesday) and 5 times over 4 weeks by applying 25 ⁇ L of 0.15% DNFB solution to both sides of the mouse auricle.
- 1% This compound ointment 1% this compound + 9% white petrolatum
- white selenium 5 times a week (Monday to Friday) from the day before the first DNF ⁇ coating to the day before the 5th application 2
- mice were injected with 0.2% E vans B 1 ue solution from the tail vein, 2 hours after dye tail vein injection (2 hours after application), and the mice that were the site of dye leakage The pinna was removed and the pigment was extracted with a pigment extract. Subsequently, the absorbance of the extracted dye was measured, and the amount of the leaked dye was calculated from the obtained absorbance to evaluate the action of the present compound against dermatitis.
- Table 4 shows the average value and color of the leaked pigment 2 hours after the 5th DN 'FB application. (1 [Amount of leaked pigment in this compound ointment group] [White amber serine group 0 0 Table 4
- the amount of leaked pigment after DNFB application in the group treated with this compound is significantly reduced compared to the white petrolatum group, so this compound is useful as a therapeutic and preventive agent for atopic dermatitis. It is.
- plasticity Hydrophyll Proper amount By changing the amount of this compound added, the concentration will be 0.0 1% (w / w) (ointment B— 2), 0.1% (w / w) (ointment Ointments of B-3), 3% (w / w) (ointment B-4) and 10% (w / w) (ointment B-5) can be prepared.
- Industrial applicability 0.0 1% (w / w) (ointment B— 2), 0.1% (w / w) (ointment Ointments of B-3), 3% (w / w) (ointment B-4) and 10% (w / w) (ointment B-5) can be prepared.
