Keywords

Broccoli sprouts, alcohol sensitivity, sulforaphane, alcohol metabolism, in the Asian Community

Brief summary

This study is designed to determine whether Asians who are especially sensitive to alcohol exposure can be protected by boosting their activities of an alcohol disposing enzyme. This will be accomplished by administering broccoli sprouts that are rich in an agent that increases protective enzyme activity. The test system involves applying alcohol patches to the skin and measuring skin redness.

Interventions

150 nanomol of sulforaphane/cm2 of skin in 80% acetone for 3 applications on 3 successive days prior to alcohol challenge

MeasureTime frameDescription
Mean Area of Skin Erythema (Skin Redness)mean up to 2 hoursFor three days in a row, volunteers will receive skin treatments with broccoli sprout extract. On day four, their skin will be measured for a baseline skin color reading. Immediately following this reading, the treated areas of the skin will be challenged with 70 percent alcohol and the redness of the skin will again be measured every 30 minutes for the following two hours for skin color changes. The values were collected every 30 minutes after the alcohol skin challenge for 2 hours and were averaged. Mean and 95% Confidence Interval are reported.

Outcome results

Primary

Mean Area of Skin Erythema (Skin Redness)

For three days in a row, volunteers will receive skin treatments with broccoli sprout extract. On day four, their skin will be measured for a baseline skin color reading. Immediately following this reading, the treated areas of the skin will be challenged with 70 percent alcohol and the redness of the skin will again be measured every 30 minutes for the following two hours for skin color changes. The values were collected every 30 minutes after the alcohol skin challenge for 2 hours and were averaged. Mean and 95% Confidence Interval are reported.

Time frame: mean up to 2 hours

Population: Since experimental conditions were refined part way through the series and only the last 19 individuals' data was deemed suitable for analysis.
