Résumé
By searching and analizing the related literatures of recent years, the extraction methods, biological activites and application of yeastβ-glucan were reviewed.It is found that there are many kinds of extraction methods, including acid method, alkali method, acid-alkali method, alkali-enzymatic method, autolysis-enzyme-alkali method, induced autolysis-alkali method, microwave assisted alkali-enzyme method, autolysis-ultrasonic coupling method, enzymatic method, etc.There are lots of biological activity study report on yeast β-glucan, envolving the activities of immune, anti-tumor, anti-oxidant, anti-radiation, lowering blood lipid, and regulating intestinal flora as prebiotics, etc.Yeast β-glucan is widely used in animal breeding industry, food industry and cosmetics industry.From the review we can know that seeking efficient, fast, pollution-free yeastβ-glucan extraction methods is the hot research point, and it will have more applications in food and cosmetics industries as good biological response regulator in the future .
Résumé
Objective:To investigate the efficacy of lauromacrogol injection for the treatment of post-operative breast cancer lym-phatic fistula. Methods:A mixture of lauromacrogol and air from the drainage tube was injected to the treatment group. The site of the residual cavity was bound with appropriate pressure for 24 h. The control group was treated with traditional methods. Results:The lym-phatic fistula of the treatment group disappeared after the mixture of lauromacrogol and air was injected to the patients. All of the 12 cases were subjected to a follow-up session. No recurrence of lymphatic fistula was observed. The differences between the treatment group and the control group were significant. Conclusion:The results revealed the efficacy of lauromacrogol injection for the treatment of post-operative breast cancer lymphatic fistula. Hence, this method could be applied for the preliminary treatment of lymphatic fistula.
