Inhibitory Effects of Shikonin Dispersion, an Extract of Lithospermum erythrorhizon Encapsulated in ß-1,3-1,6 Glucan, on Streptococcus mutans and Non-Mutans Streptococci.

Shikonin is extracted from the roots of Lithospermum erythrorhizon, and shikonin extracts have been shown to have inhibitory effects on several bacteria. However, shikonin extracts are difficult to formulate because of their poor water solubility. In the present study, we prepared a shikonin dispersion, which was solubilized by the inclusion of ß-1,3-1,6 glucan, and analysed the inhibitory effects of this dispersion on Streptococcus mutans and non-mutans streptococci. The shikonin dispersion showed pronounced anti-S. mutans activity, and inhibited growth of and biofilm formation by this bacterium. The shikonin dispersion also showed antimicrobial and antiproliferative effects against non-mutans streptococci. In addition, a clinical trial was conducted in which 20 subjects were asked to brush their teeth for 1 week using either shikonin dispersion-containing or non-containing toothpaste, respectively. The shikonin-containing toothpaste decreased the number of S. mutans in the oral cavity, while no such effect was observed after the use of the shikonin-free toothpaste. These results suggest that shikonin dispersion has an inhibitory effect on S. mutans and non-mutans streptococci, and toothpaste containing shikonin dispersion may be effective in preventing dental caries.

Case Report: A Non-small Cell Lung Cancer Patient Treated with GcMAF, Sonodynamic Therapy and Tumor Treating Fields.

BACKGROUND/AIM: Macrophage activating factor (MAF)-based immunotherapy has a wide application for use in treating many diseases via macrophage activation. Sonodynamic therapy (SDT) using low-intensity ultrasound and tumor treating field (TTF) therapy are novel therapeutic modalities. SDT is usually combined with ozone therapy to improve local hypoxia within the tumor environment. CASE REPORT: We treated a 77-year-old male diagnosed with non-small cell lung cancer ((NSCLC) stage 3B) using second-generation serum GcMAF and oral colostrum MAF-based immunotherapy combined with SDT, TTF and ozone therapies. RESULTS: This case report demonstrates that GcMAF, oral colostrum MAF, SDT, TTF and ozone therapy can be used for NSCLC without adverse effects. CONCLUSION: This case report suggests a new concept of cancer treatment using local destruction of cancer tissue, in this case conducted with SDT and TTF therapy, to be used in combination with serum GcMAF and colostrum MAF immunotherapy as a systemic treatment.

Oral Colostrum Macrophage-activating Factor for Serious Infection and Chronic Fatigue Syndrome: Three Case Reports.

BACKGROUND: Gc protein-derived macrophage-activating factor (GcMAF) immunotherapy has been steadily advancing over the last two decades. Oral colostrum macrophage-activating factor (MAF) produced from bovine colostrum has shown high macrophage phagocytic activity. GcMAF-based immunotherapy has a wide application for use in treating many diseases via macrophage activation or for use as supportive therapy. RESULTS: Three case studies demonstrate that oral colostrum MAF can be used for serious infection and chronic fatigue syndrome (CFS) without adverse effects. CONCLUSION: We demonstrate that colostrum MAF shows promising clinical results in patients with infectious diseases and for symptoms of fatigue, which is common in many chronic diseases.
