Study of some detoxification properties of a sorbent based on silicon dioxide

Abstract

Veterinary sorption preparations are medicinal substances and substances that absorb gases, solid and liquid substances on their surface by adsorption. The purpose of our research was to study the detoxification properties of a sorbent based on silicon dioxide (ADC) obtained from rice processing industry waste during heavy metal poisoning in rats. Mercury dichloride was used for experimental poisoning with heavy metals. Nonlinear rats from the nursery of the RAMS "Rappolovo" were used for the experiment. The live weight of the animals averaged 120 g. 3 groups of animals with 20 rats in each were formed. Group No. 1 received the basic diet, ADC and mercury dichloride, group No. 2 – the basic diet and mercury dichloride in the amount of 25 mg per head. Group No. 3 is a control group, which was fed only the basic diet. The experience lasted 14 days. The results were evaluated by the live weight of animals, clinical blood examination, leukogram examination, pathoanatomic autopsy and massometry of internal organs of rats. In study group No. 1, there was no decrease in the body weight of rats during the 14 days of the experiment, while in study group No. 2, where the sorbent was not used, the body weight of rats decreased by 13.79 g. At the end of the experiment, a pathoanatomical autopsy of the animals was performed. In group No. 1, hemorrhages were observed in the mucous membrane of the stomach and intestines. In group No. 2, hemorrhages in the gastric mucosa, damage to the intestines, gallbladder and kidneys were noted, where serous infiltration of connective tissue, large spotty hemorrhages in the serous and mucous membranes were observed. There were no changes in the stomach, intestines, and kidneys in group No. 3. Based on the data obtained, it can be concluded that there are detoxifying properties of a veterinary sorption preparation based on silicon dioxide obtained from rice husks.
