  • In this study, we have investigated the antibacterial, antioxidant, and antitumor activities of mycelium cultural extract from mushroom. Mushroom mycelium was grown in a synthetic liquid media such as PD broth, YM broth or citrus extracts. In antibacterial activity test, the best result was achieved when mycelium cultural extracts from Phellinus linteus and Coriolus versicolor were incubated together on YM broth. On the other hand, mushroom mycelium cultured on citrus extracts showed better activity than that on PD broth. We have also tested the antioxidant activity at concentration up to 10 mg of mycelium cultural extract/mL. The more it is in higher concentration, the more the activity increases. The higher antioxidant activity was observed both on PD broth containing the Phellinus linteus and Coriolus versicolor mycelium and citrus extract containing the same. The complex culture extracts obtained from the synthetic medium and citrus extract medium showed 10-89% of the 1,1-diphenyl-2-picrylhydrazyl radical scavenger activity. The antitumor activity of mycelium cultural extract was examined by using MTT assay on A549 cells. Mushroom mycelium cultured on citrus extracts showed interestingly higher antitumor activity than that on synthetic liquid media.

  • We have investigated the effects of mushroom mycelium (Phellinus linteus, Coriolus versicolor) mixed cultural extract on the immune responses of olive flounder, Paralichthys olivaceus. The mixed culture extracts were evaluated for the growth, hematology, lysozyme activity, leukocyte phagocytic activity, and disease resistance against Vibrio anguillarum. In the effect of the growth, the body weight and length gain in the group, which fed with mushroom mycelium mixed cultural extract, were 52 g and 3.4 cm higher than that in the control, respectively. For the hematology, the administration of mushroom mycelium mixed cultural extract resulted in increase of glucose. However, there was no distinct differences in GOT (glutamic oxaloacetic transaminase), GPT (glutamlc pyruvic transamlnase), TG, TP, and LDH (lactate dehydronase) among each group. The activities of lysozyme were 80% higher in the experimental groups than in the control. The activities of leucocyte were 66% higher in the experimental groups than in the control. Although lysozyme activity and leucocyte activity showed somewhat decrease after 12 weeks, these activities were still higher than in the control. The cumulative mortality (%) after an artificial challenge with $7{\times}10^8\;CFU$ of Vibrio anguillarum per fish was 25% higher in the experimental groups than the control.

Study of Effects and Optimum Concentrations of Medical Herb Extracts on Blood Glucose and Serum Lipid in Streptozotocin-Induced Diabetic Rats (Streptozotocin 유발 당뇨 쥐의 혈당 및 혈청 지질에 미치는 한방추출물의 효과와 최적 농도에 관한 연구)

  • Objectives : The purpose of this study was to investigate effects of extract from mixed culture with Tricholoma matsutake mycelium and Cordyceps militaris mycelium in oriental medicine and cereal midium (OCM) considered effective for the treatment of diabetes. Methods : We examined antioxidant activity and $\alpha$-glucosidase inhibit activity of OCM and orally administered OCM extracts to Streptozotocin-induced diabetic ratsat the dose of 100mg/kg, 200mg/kg and 300mg/kg body weight. Results : Total polyphenol content of extracts of OCM was 26.41 mg/g, DPPH radical scavenging activity was 32.24% and SOD-like activity was 31.43%. $\alpha$-glucosidase inhibit activity showed 85.3% of acarbose. Blood glucose levels of the OCM extracts-treated groups were lower than those of the diabetic control group (DC), total cholesterol and triglyceride contents were similar to the acarbose-treated group (PC) and ALT, AST were lower than the DC and PC groups. The 300 mg/kg body weight administered group (UM-300) were superior to other OCM-treated groups (UM-100, UM-200). Conclusions : These results showed extract from mixed culture with Tricholoma matsutake mycelium and Cordyceps militaris mycelium in oriental medicine and cereal midium has potentiality to beused in pharmaceutical products and medicinal food for preventive and treatment diabetes mellitus.

  • Termitomyces sp. that grow in symbiosis with fungus-farming Termites have medicinal properties. However, they are rare in nature, and their artificial culture is challenging. The expression of AXL receptor tyrosine kinase and immune checkpoint molecules favor the growth of cancer cells. The study evaluated the optimal conditions for the artificial culture of Termitomyces and their inhibitory activity on AXL and immune checkpoint molecules in lung adenocarcinoma and melanoma cell lines. The culture of 45 strains of Termitomyces was compared. Five strains with marked growth rates were selected. Four of the selected strains form a single cluster by sequence analysis. The mycelium of 4 selected strains produces more fungal mass in potato dextrose broth than in a mixed media. The bark was the most appropriate solid substrate for Termitomyces mycelia culture. The mycelium of all five selected strains showed a higher growth rate under normal CO2 conditions. The culture broth, methanol, and ethyl acetate of one selected strain (T-120) inhibited the mRNA relative expression of AXL receptor tyrosine kinase and immune checkpoint molecules in cancer cell lines. Overall, these results suggest the potential usefulness of Termitomyces extracts as a coadjuvant therapy in malignant diseases.

  • Objectives : The purpose of this study was to investigate extracts from mixed culture of Oriental medicines and cereal medium and mycelia of Trichloma matsutake and Cordyceps militaris by fermentation to develop new material for pharmaceutical products and medicinal food, Methods : To evaluate physiological activities of OCM extracts, we examined antioxidant activity(total polyphenol contents, electronic donating ability, SOD-like activity), ${\beta}$-glucan contents, nitric oxide production and cytotoxicity by MTT assay. Results : Total polyphenol contents of fermented OCM(UF) and non-fermented OCM(UM) extracts were more than 40% UM and UF of DPPH radical scavenging activity was 25.67%, 23.43% respectively. Total polyphenol content of non-fermented extract (UME) was 12.57%, while that of fermented extract(UFE) was 7.05%. SOD like activity showed UM 85.35%, UF 76.18%, UME 58.42%, UFE 72.21%. UME, and UFE 31.43%, ${\beta}$-glucan contents of UME and UFE were more than 40%. NO productions of UME, and UFE showed a LPS dose dependent tendency. Cytotoxicity on Raw 264.7 cell showed more than 90% viability. Inhibitory effect of UFE on HT1080 cell growth was higher than UME. Conclusions : These results showed that extracts from mixed culture of mushroom mycelium and OCM have physiological activities which can be used in pharmaceutical products and medicinal food.
