Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will enroll 150 healthy volunteers, and the grouping is as follows: group 20-39 (30 males and 30 females); group 40-59 (30 males and 30 females); and group 60-79 (15 males and 15 females). The sublingual microcirculation will be examined with the incident dark field video microscope (Cytocam，Braedius Battery Powered Transilluminator). The study aims to compare the differences of microcirculation among the three groups and between genders.
