RADIATION STERILIZATION OF TRADITIONAL MEDICINE DRUGS IN VIETNAM

With the application of Gamma Co-60 radiation sterilization in pharmac eutical industry, attention should be paid to the possibilities of ste rilizing traditional medicine drugs produced in Vietnam. In this paper the opinion which traditional medicine drugs can be satisfactorily st erilized by irradiation is based on the changes of physical and chemic al properties of the products and microbiological examinations. The st erilizing radiation dose were calculated and the results are the follo wing (in Mrad) Rheumatine-2.2, Hasinh-3.3, snake extract-1.8, Samcotgi ao-2.2. The changes of physical and chemical properties of the product s and their toxicity after irradiation have been shown to be not over the levels of allowance.
