Brief Summary

This study was conducted to investigate the efficacy and safety of SGF200 on immune enhancement.

Detailed Description

This study was a 8 weeks, randomized, double-blind, placebo-controlled human trial. 100 subjects were randomly divided into SGF200 group or placebo group. The investigators measured Natural Killer cell activity, Cytokines(IL-2, IL-12, IFN-γ, TNF-α), questionnaire scores of upper airway infection.

Primary Outcome Measures
NameTimeMethod
Changes of Natural Killer cell activity8 weeks

Natural Killer cell activity was measured in study baseline and 8 week. A ratio of effector cell and target cell was 2.5:1, 5:1, 10:1

(Experimental - Effector Spontaneous - Target Spontaneous) / (Target Maximum - Target Spontaneous) × 100

Secondary Outcome Measures
NameTimeMethod
Changes of Wisconsin Upper Respiratory Symptom Survey-218 weeks

Wisconsin Upper Respiratory Symptom Survey-21 consists of seven steps, including individual symptoms, functional quality of life, and overall improvement. Find the sum of the symptom questions and give them the total score. Seek, sum up the questions of life, and get the total quality of life. The sum of the total score of symptoms and the total score of quality of life is also obtained.

Changes of Cytokines8 weeks

For blood Cytokines analysis, collect 3 ml of blood in one SST tube for 5 ml, leave at room temperature for 30 minutes for clotting, after then centrifuge at 3000 rpm (or 2000 xg) for 10 minutes.

Inspection item were IL-2, IL-12, IFN-γ, TNF-α.
