Process for the obtaining of polymers with activity on the hematopoietic system.

摘要

Described herein is a process for the obtaining of polymers which are of polysaccharide character with activity upon the hematopoietic system, said polymers being obtained from polycarboxylated polysaccharides such as alginic acid, gum arabic or gum tragacanth of diverse biological sources, which process consists in the ultrasonic irradiation of well-defined aqueous suspensions of said polymers under specified conditions of amplitude, frequency, time and temperature, after which the products thus obtained are purified by means of exhaustive dialysis and are given the form of solids by means of lyophilization or spray-drying, the products themselves being endowed with an effect upon the activity of the hematopoietic system. The process has applications in the pharmaceutical industry.
