Wang & ACTIVITY FROMIMEDICINAL Ng (2000) isolated a novel ubiquitin-like glycoprotein from MUSHROOMS Oyster mushrooms (Pleurotus Ostreatus) that demonstrated inhibitory activity toward the HIV-1 reverse transcriptase.

In response to hot water pox, influenza, SARS, Hepatitis, Tuberculosis, Escherichia extracts of Reishi mushrooms, preserved in ethanol, Versus coli and Staphylococcus aureus and other viruses and bacte saline controls, NK cell activity was significantly augmented 18. 15 when cancer cells were co-cultured with human spleen cells. 2.

As the water extract of the fruitbodies is search for new antimicrobial and antiviral agents, some of high in beta glucans while the mycelium-on-rice is low in beta which have proven to be of significant commercial value. A glucans, but is high in arabinoxylanes, two causal agents are major difficulty in the discovery of antimicrobial and antiviral identified as NK effectors. Both the extract and the heat agents is their inherent toxicity to the affected host organism. treated, freeze dried, powdered mycelium from 7 species For instance, a novel agent or treatment that kills the virus but share common activity levels of enhancing NK activity by also harms the human host is neither medically practicable 300+%.
