METHOD FOR PRODUCING AN IMMUNOTROPIC ANTIVIRAL PREPARATION

摘要

The invention relates to the chemical pharmaceutical industry, in particular to a method for producing an immunotropic preparation exhibiting a high antiviral activity with respect to RNA and DNA viruses. In order to produce the inventive preparation, fat-free sturgeon or salmon milt, or a calf thymus, or chicken blood, or porcine liver is pulverised and homogenised in a saline citrate solution. The produced homogenate is incubated in the presence of a detergent, a calcium chlorine solution being added at a high temperature. Afterwards, said homogenate is treated by ultrasound, a sorbent and detergent and concentrated, thereby producing a white amorphous deposit of DNA which has the following characteristics: a molecular mass ranging from 270 to 500 kD, a hyperchromatic action not less than 37 %, a protein content of less than 1 %. The DNA deposit is dried and the obtained powder is diluted in an aqueous solution of the following transition metal: Zn, Co, Mn, Sb, whereby a 1.5 % sterilised solution having a hyperchromatic action equal to or higher than 10 % is obtained.
