Both bee products themselves and their combinations are widely represented in the domestic pharmaceutical market, however, modern experimental studies of the biological activity of these compounds are few, and in many of the existing publications the authors describe an extremely wide and controversial range of therapeutic effects.The aimof the study is to analyze the experimental works on the study of biological activity of bee products.Materials and methods.The study was conducted using search and information (eLibrary, PubMed, CyberLeninka, ResearchGate) and library databases (Russian State Library, Central Scientific Agricultural Library). In the designated databases, publications were searched by such terms as “biological activity”, “royal jelly”, etc. The depth of the search was not limited.Results and discussion.The analysis of the published works shows that such substances as bee venom and royal jelly have experimentally confirmed their biological activity. In both cases, the active substances have been described and a review of their detected biological activity has been carried out.Conclusion. The authors suggest that when developing the method of laboratory synthesis of decene acids, it can be possible to carry out their large-scale preclinical research, which may become the basis for the creation of a drug with a selective effect.
A comparative study of acute toxicity of nifuroxazide preparations in form of suspension has been carried out. Mature individuals of white mice (weighing 18-20 g at the age of 8-9 weeks) and rats (weighing 160-180 g at the age of 13-14 weeks) of both sexes were under observation. The administration of the suspensions was performed in increasing doses by Litchfield-Wilcoxon, dosing was carried out by volume on the total mass of the suspension. The recorded indicators were mortality, time of death of animals, symptoms of poisoning, autopsy, description of animals at the end of the study, determination of mass coefficients of internal organs.The compared drugs («Nifuroxazide», suspension for oral administration 200 mg/5 ml, LP 004858 dated 23.05.2018 and «Enterofuril», suspension for oral administration 200 mg/5 ml N014624/02 dated 06.11.2008) are equivalent in terms of acute toxicity, belonging to class VI of relatively harmless drugs, have similarities in the parameters of acute toxicity, the picture of intoxication is the same, and there are not detected signs of damage of internal organs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
