    摘要: A process for producing a hepatitis B infection preventing vaccine containing hepatitis B surface antigen as a main component thereof which comprises removing human plasma components possibly causing adverse effects and components capable of causing hepatitis B infection by incorporating steps of fractionation using ammonium sulfate, adsorption on a colloidal silicate and fractionation using polyethylene glycol into the purification stage after heat treatment and further carrying out a treatment for infectivity inactivation without causing any antigenicity impairment.

    摘要: An aqueous solution of haptoglobin is obtained by subjecting an aqueous solution of .alpha. and .beta.-globulin fractions of human blood plasma to further fractionation by use of ammonium sulfate, collecting fractions precipitated at a concentration between 30% and 40% saturation of ammonium sulfate, contacting a reconstituted aqueous solution of the collected fractions with an anion exchanger to adsorb haptoglobin on said anion exchanger, selectively eluting the haptoglobin from the anion exchanger, and then concentrating the resulting aqueous eluate solution. The aqueous solution of haptoglobin is subjected to heat treatment in the presence of a selected stabilizing agent for inactivating hepatitis B virus at an optional step of the process.The thus obtained aqueous solution of haptoglobin has less than 10% hypotensive activity, highly stable during storage, and free from the risk of hepatitis B virus infection. This haptoglobin preparation is used for prevention and treatment of renal disorders caused by hemolysis.
