简要总结
The investigators investigate the effect of Chungkookjang on histamine-induced skin reaction in a double-blind, randomized, placebo-controlled, human trial
详细描述
Sixty volunteers (aged 20-80) who gave a written consent before entering the study, were randomized in two groups of thirty subjects each. The skin prick test with histamine was performed on the ventral forearm, 10 cm from the elbow, before and after supplement administration, as well as three times daily for 12 weeks of chungkookjang(35g/day) or placebo(35g/day)intake.

结局指标
主要结局
Changes in Histamine-induced Wheal Size
时间窗: 12weeks
Histamine-induced wheal size was measured in study visit 1(0 week) and visit 3(12 week).
Number of Participants With Greater Than 40% Decrease in Histamine-induced Wheal Size (Wheal Size by More Than 40% Decrease in the Number of Subjects Compared With Placebo)
时间窗: 12weeks
Number of Participants with Greater than 40% Decrease in Histamine-induced Wheal Size was measured in study visit 1(0 week) and visit 3(12 week). Percentage change in histamine-induced wheal size calculations were calculated by the formula ((12weeks - 0weeks) \* 100/0weeks). Number of Participants with Greater than 40% Decrease in Histamine-induced Wheal Size compared with placebo.
