[Preclinical toxicological study of D-glucuronic acid]

A new D-glucuronic acid (DGA) preparation was studied for toxicological safety on a preclinical level. The results obtained upon a single acute DGA administration in rats, mice, and rabbis showed that the drug exhibits moderate toxicity. A one-month treatment of rats (at a single daily dose of 50, 250, and 500 mg/kg, i.p.) and dogs (50 mg/kg, i.v.) induced neither functional nor morphological changes in hemopoietic and lymphoid organs, kidney, heart, as well as in the digestive, nervous, hemostatic, and fibrinolytic systems. The intraperitoneal administration of DGA produced a pronounced local irritation effects. The liver of both rats and dogs treated with DGA showed dose-dependent adipose degeneration, which decreased upon the drug abolition. The administration of DGA in 50, 100, and 250 mg/kg doses led to dose-dependent changes in some characteristics of the reproductive system in rats. DGA did not modify the extent of allergic reactions and showed no immunotoxicant and mutagen properties.
