ABSTRACT:
The invention relates to new medicaments useful for the treatment of leucocyte and platelet deficiencies, which medicaments are polyribonucleotides prepared by degradation of the ribosomic ribonucleic acids extracted from micro-organisms of from animal organs and are formed of simple chains or "RNA fragments" comprising about 20 to 80 ribonucleotide units, the overall ratio of purine bases (G+A) to pyrimidine bases (C+U) being between 1.0 and 2.5.
The invention also relates to a process for the preparation of these polyribonucleotides by scission of the ribosomic ribonucleic acids extracted from suitable micro-organisms, by means of a ribonuclease or of a chemical reagent such as an alkali metal base.
