Title Of The Study: Examination of clinical effect of y-oryzanol combination Ointment

After investigating the sebum secretion promoting action, safety and clinical effect of y-oryzanol ointment, the following conclusions were obtained.(1) The following results were obtained by externally applying 0.1%, 1%, and 2% Y-oryzanol ointment and base to the forearm skin by a double-blind method and measuring the amount of normal sebum. No increase in sebum was observed at low concentrations, and a significant increase was observed at 1% or higher, but no significant difference was observed between 2% and 1%.(2) As a result of a patch test with 65 patients in the normal group and 37 patients in the patient group, it was confirmed that 1% y-oryzanol ointment (y) was less irritating to the skin, did not change due to the influence of light, and was highly safe locally on the skin. bottom.(3) When a clinical study was conducted in accordance with the double-blind method using the base as a control, a slow clinical effect was observed for diseases in which sebum secretion may be decreased, especially senile xeroderma. The incidence of side effects was low and the symptoms were minor.

Title Of The Study: Examination of clinical effect of 1% y-oryzanol combination ointment

Title Of The Study: Y -Oryzanol Effect of topical use on sebaceous glands

y -Oryzanol is known to have metabolic function-activating and activating effects such as growth promotion and gonad stimulation by systemic administration. It is similar to vitamin E in terms of local action. Kamimura et al. Have reported that it affects the microcirculatory function of the skin and directly raises the skin temperature. We experienced the tendency to induce acne using y -oryzanol cream for the treatment of pimples, and inferred that y-oryzanol) has the effect of activating the sebaceous glands, and the local sebum secretion amount of y -oryzanol. A double-blind test was performed with 1% y -oryzanol cream as a control for placebo with only the base. It was applied to the forearm of a normal person for I month, and the sebum of the skin was collected by the cup method, the total lipid was quantified by the chromium acid oxidation method, and the amount of lipid peroxide was measured by the TBA method. As a result, a significant increase in the total lipid content of sebum was observed. In addition, there was no difference in the amount of lipid peroxide and the ratio of the amount of lipid peroxide to the total amount of lipid.
