摘要: Aim of this study was to investigate the effect of ultrasonic treatment on the biological activities of schizophyllan (SPG) from Schizophyllum commune. The immunoregulatory and antitumor activity in vitro and in vivo of SPG and ultrasonic-treated SPG (USPG) were evaluated by splenic lymphocytes, macrophages RAW264.7 and human breast carcinoma T-47D cells. Compared with SPG, USPG fractions had small molecular weight and narrow distribution. Meantime, more enhancement of NO production in macrophages RAW264.7, lymphocytes proliferation rates, IL-2 and TNF-alpha level from spleen lymphocytes and T-47D cells inhibition rates were observed in USPG fractions groups. This result indicated that the immune-enhancing and antitumor activity of SPG was significantly improved after ultrasonic treatment. USPG60 exhibited the highest biological activity in this study. In conclusion, application of ultrasonic technology on SPG preparation is an efficient approach to get high biological polysaccharide, and USPG60 might be a potential functional component for immunoregulatory and cancer treatment.
