This study was conducted to investigate the physiological activities of the water and methanol extracts from Auricularia auricula-judae(black and brown) and Auricularia polytricha. Largely, anti-oxidant, anti-tumorigenic, anti-inflammatory, anti-diabetic activities were carried out. DPPH scavenging activity was performed on the anti-oxidant test. MTT assay and nitrite scavenging acitivity were performed on the anti-tumorigenic test. The cancer cell were used to HeLa, A549, HT-29 and MCF-7 and normal cell was used as control. lastly, in the anti-inflammatory and anti-diabetic activities, NO assay and α-amyloglucosidase inhibition were performed, repectively.

The genus Micromus is a large group, belongs to the family Hemerobiidae with a worldwide distribution. This genus was named by Rambur, 1842 based on the type species Hemerobius variegates Fabricius, 1793. Eighty five species have been described from the world. Among them only one species, M. numerosus (Navás), has been recorded from Korea. Morphologically, Micromus is easily distinguished from other hemerobiid genera by the combination of the following characteristics: maxillary palpus 5 segments, labial palpus 3segments; forewing with costal area quite narrow at base and one prestigmal Sc-R crossvein, without recurrent humeral vein and crossvein 2M-Cu. Members of the genus Micromus are generally considered to be beneficial as predators of various aphids, particularly on sugar cane and corn plants. This genus occurs in a variety of habitats including both trees and grasses. It is often found in alfalfa fields where both larvae and adults feed on aphids. Adults are also highly attracted to lights at night. In this reviewing study about the Korean Micromus, we study two species. M. angulatus (Stephens) and M. numerosus (Navás). Among them M. angulatus is newly included in Korean fauna. We also provide a key to the Korean species of Micromus, description, illustrations of diagnostic characters and distributional data.
