Cancer prevention and treatment glucosan and yeast cell wall extract for oral administration

Abstract

The invention relates to cancer prevention and treatment glucosan and a yeast cell wall extract for oral administration. The cancer prevention and treatment functional ingredients of the glucosan arebeta-1,3-1,6-glucosan units with specific branch structures; the glucosan is obtained in a mode of orally taking the yeast cell wall extract; the yeast cell wall extract contains 75 to 95 percent of beta-1,3-1,6-glucosan; the glucosan branch chains are of long branch chain structures; the content of the branch chain glucosan accounts for 18 percent or higher of the total quantity of the glucosan;when the glucosan is used for preventing and treating the cancer; the oral administration dose every day is 0.01 to 0.2 g / kg body weight; the duration is at least 10 months. The invention provides theglucosan structure with exact and stable anticancer effects; the yeast cell wall extract capable of being orally taken and capable of being finally absorbed through intestinal tracts to obtain the beta-1,3-1,6-glucosan branch unit is provided. When the glucosan is matched with conventional operation, radiotherapy and chemotherapy, a patient can obtain the treatment effect of recovering the carcino-embryonic antigen to the normal people level to the optimum degree.

Description

technical field [0001] The invention relates to the field of medicine and health care, in particular to a glucan with the effect of preventing and treating cancer and an oral yeast cell wall extract. Background technique [0002] Dextran refers to a homopolysaccharide composed of glucose as a monosaccharide, and the glucose units are connected by glycosidic bonds. With the different types of microorganisms and growth conditions, their structures are also different. Among the glucans, β-glucan is the most physiologically active. The active structure of β-glucan is a polysaccharide composed of glucose units, most of which are combined by β-1,3, which is the way of glucose chain connection. It can activate macrophages and neutrophils, etc., so it can increase the content of leukin, cytokinin and special antibodies, and fully stimulate the body's immune system. β-glucan can quickly restore the ability of lymphocytes in the injured body to produce cytokines (IL-1) to normal, an...

Problems solved by technology

At present, a large number of studies are using β-1,3 / 1,6-glucan combined with monoclonal antibodies and other anti-cancer components to form compositions for anti-cancer, using β-1,3 / 1,6-glucan The characteristics of the components of glycans also recognize that there are various structures of β-1,3 / 1,6-glucan, but the relationship between the specific structure of β-1,3 / 1,6-glucan and the anticancer effect relationship has not yet been reported
