[The specific features of the distribution of 4-metoxyhydroxybenzene in the organism of the warm-blooded animals suffering lethal intoxication].

This work was designed to study the distribution of 4-metoxyhydroxybenzene in the organism of the omnivorous warm-blooded animals (rats) after the intragastric administration of this poisonous compound at a dose three-fold greater than the LD50 value. The administered 4-metoxyhydroxybenzene was isolated from the organs and blood of the experimental animals by exposing the biological tissues to acetone with subsequent purification on a silica gel L 40/100 mcm using a hexane:dioxane:propanol-2 (20:5:1) as the mobile phase. The identification and quantitation of 4-metoxyhydroxybenzene were carried out with the use of TLC, GC-MS, and UF-spectrophotometry. It was shown that the administered 4-metoxyhydroxybenzene remained unmetabolized in the internal organs and blood of the poisoned experimental animals. The largest amounts of 4-metoxyhydroxybenzene were found in the stomach contents (2584,92±117,47), brain (59.49±6.05), contents of small intestines (28.21±3.77), and kidneys (26.13±1.64).
