Preliminary Experimental Adaptation Of VNUCOVO - 32 Rabies Vaccine Strain into Vero Cell

Introduction: Rabies is a serious problem in the area of public health in developing countries including Vietnam. The death rate is almost 100%, however rabies can be prevented and preventively treated by vaccine, or a combination between vaccine with rabies resistant serum. The production of Vero cell culture vaccine is becoming a common trend worldwide because of its effective protection and safety. There is a requirement for the domestic production of cell cultured rabies vaccine. \r\n', u'Objectives: To determine the adaptive ability of VNUCOVO - 32 rabies vaccine strain into Vero cell. \r\n', u'Subjects and Method: Rabies vaccine propagation strains the rat\u2019s kidney cells. VNUCOVO - 32 was cultured into Vero cell with different conditions such as pH, temperature, multiplicity of infection (MOl) and time of virus harvests to discover the optimal conditions for virus propagation. \r\n', u'Results: The optimal condition for VNUCOVO - 32 propagation into vero cell with MOl 0.3, pH 7.4 and temperature is 37\xb0C. The highest titer achieves 103,4FFLJ/ml. The best time for virus harvest is 12 - 13 days post inoculation. \r\n', u'Conclusion: VNUCOVO rabies vaccine strain can penetrate and propagate into vera cell. \r\n', u'

Study on setting up the method of quality control of iodosoja

Iodosoja is an iodine containing organic compound to treat the goiter. This study aimed at setting up the method of quality control of iodosoja. The method involved the qualitative analysis (physical and chemical properties), quantitative analysis (quantification of free iodine, and total organic iodine as chemical method and spectrometry) and determination of stability (selflife) of iodosoja
