Toei Shinyaku Co., Ltd. (Headquarters: Mitaka City, Tokyo; Representative Director: Akimoto Motoi) is pleased to announce that the research findings on the wound healing promotion and skin-beautifying effects of King Agaricus KA21, outdoor cultivated Agaricus blazei / brasiliensis (KA21 strain) have been published as our 34th international paper.

Overview

■ Co-Research Conducted by

Department of Immunology, School of Pharmacy, Tokyo University of Pharmacy and Life Sciences

■ Abstract

Royal sun medicinal mushroom Agaricus brasiliensis KA21 has various beneficial pharmacological effects; however, these effects are influenced by its cultivation conditions. A. brasiliensis KA21 is rich in β-glucan, which promotes wound healing. This study evaluated the wound healing-promoting effects of A. brasiliensis KA21 and the influence of cultivation conditions on these effects. Upon evaluation of its effect on wound healing, the outdoor-cultivated A. brasiliensis KA21 (KAOD) promoted wound healing in mice, and the effect of KAOD was stronger than that of the indoor-cultivated one (KAID). In addition, A. brasiliensis KA21 promoted the synthesis of collagen I and III, which are involved in promoting wound healing; KAOD strongly induced collagen III production. Furthermore, KAOD suppressed the decrease in skin elasticity after acetone application in our mouse model, which was not observed for KAID. These results show that KAOD is useful as a supplement in surgery and injury healing for humans and animals, improving immunity against pathogens in wound areas and promoting wound healing. In addition, KAOD may be useful in the field of skin aesthetics for repairing skin damage and maintaining skin elasticity.

■ Application of Outdoor cultivated King Agaricus KA21 Strain as a Supplement for Post-Surgery Early Recovery

We have previously conducted surveys on the wound healing promotion effects of the outdoor cultivated King Agaricus KA21 strain.

 Survey on Cosmetic Surgeons

In a survey conducted with cosmetic surgeons, 18 patients who underwent cosmetic surgery were administered a supplement containing 1600mg of outdoor cultivated King Agaricus KA21 for six days. The satisfaction rate among the surgeons (very satisfied and satisfied) was found to be 93.3%, indicating a very high level of satisfaction.

Survey on Veterinarians and Pet Owners

In a survey involving 55 dogs and cats after surgery, they were administered a pet supplement containing 240mg of outdoor cultivated King Agaricus KA21 per 4-5kg of body weight for 7-10 days. The satisfaction rates were reported as 97.9% for veterinarians and 93.9% for pet owners at a conference.

Based on the findings from this paper and previous conference reports, the application of outdoor cultivated King Agaricus KA21 strain as a supplement for early recovery after surgery is highly anticipated.
