1 The approximate lethal dose (ALD) of six chlorinated hydrocarbons via the intratracheal route has been determined in rats and compared with published oral LD50 values. 2 The compounds tested in this study were dichloromethane, perchloroethylene, trichloroethylene, carbon tetrachloride, chloroform and ethylene dichloride. 3 A method of administering the materials intratracheally to unanaesthetized animals was developed. 4 The intratracheal ALD of the chlorinated hydrocarbons ranged from 3.1 to 17.5% of the oral LD 50 and death was peracute. 5 Aspiration of chlorinated hydrocarbons may present more of a hazard than oral toxicity and should be considered when rendering first aid or emergency medical treatment.

A range of chlorinated hydrocarbons derived from C 1 and C 2 hydrocarbons is manufactured industrially. They are used as intermediates for further chemical manufacture and also outside the chemical industry as solvents or carriers. In the latter category losses in use are eventually dispersed to the environment. The distribution of some of these compounds, including chloroform, carbon tetrachloride, trichloroethylene, perchloroethylene and trichloroethane, in the environment (air, water and marine sediments) has been investigated and the results are presented. The concentrations found have been compared with acute toxicity levels to fish and other aquatic organisms, ascertained by laboratory bioassay. The occurrence of the compounds has been determined in a number of marine organisms, especially those at higher trophic levels, and the accumulation of some of them has been investigated in the laboratory. Chemical and microbial degradation processes have been studied in the laboratory to help determine the course of their removal from the aqueous and aerial environment, and the half lives of some of the compounds have been estimated. It is concluded that these compounds are not persistent in the environment, and that there is no significant bioaccumulation in marine food chains.

The conditions for the extraction of strychnine with 1,2,2-tetrachloroethane, chloroform, 1,2-dichloroethane and carbon tetrachloride were studied and described. The distribution and extraction constants were calculated for strychnine in selected solvents from the dependence of the extraction yield on the pH at various ionic strengths. In addition, a study was carried out of the extraction properties of the ion associates of strychnine with selected groups of azodyes with identical basic skeleton but different numbers of sulfo groups.

Crystal structure prediction combined with experimental studies unveil the structural and thermodynamic features of three non-solvated forms and a carbon tetrachloride solvate of 4-aminoquinaldine and provide intriguing insights into void structures and the role of solvent inclusion.

Vector-Borne Diseases are a variety of infectious and invasive diseases of animals and humans, the agents of which extend from one to another susceptible subject with the participation of hemopoiesis (ticks, insects, etc.). For the purpose of treatment of blood parasitic transmissive diseases, domestic and foreign researchers tested a significant number of drugs of different chemical composition. In connection with the insufficient on the domestic market of drugs on the basis of imidokarb dipropionate for the treatment of blood-parasitic diseases in animals, the Scientific-Production-Technical Enterprise “Brovapharma” established and conducted the state registration of the drug “Imcar-120”, which blocks the synthesis of polyamine; it also has significantly less toxicity than dimeters of aceturates. It provides a broad spectrum of antiprotozoal effects on pathogens of pyroplasmiosis of the genus Babesia (Babesia bovis, B. ovis, B. bigemina, B. colchica, B. equi, B. divergens, B. canis, B. caballi, B. gibsonii i Francaiella colchica); Teilerian species (Theileria annulata, T. sergenti, T. mutans, T. orientalis, T. ovis, T. recondita, T. tarandirangiferis); Nuttallia equi and the genus of Anaplasma (Anaplasma marginale, A. ovis, Ehrlichia canis) with their mono- or mixed infestation. Pre-clinical research “Determination of toxicological properties of the drug Imcar-120” was carried out on the basis of vivarium of the Faculty of Veterinary Medicine of Sumy NAU. Study of parameters of acute toxicity of the study drug was performed on 50 clinically healthy white mice in males and females. Before the experiment, the individual weight of the body of animals selected for the experiment was 18–22 g, the age was 8–9 weeks. In the first stage, preliminary experimental studies were conducted to determine the variation of dose limits before the main stage of the studies. At the same time the drug was administered intragastrically in doses: 2500, 3500, 4500, 5500, 6500, 7500 mg/kg. Each dose was given to three animals. After the introduction of the drug for monitoring animals, the experiment was carried out 14 days, the first day – every hour. For the expanded stage of the experiment, four experimental groups (n = 8) of animal analogues were formed, in which the study drug was injected under the same conditions as in the previous stage of the experiment at a rate of 3800, 4300, 4800 and 5300 mg/kg of body weight.  In the course of studies to determine the parameters of acute toxicity of the drug Imkar-120 it was determined half-lettable dose of the drug. According to R. Kerber's method, DL50 was 4456.25 mg/kg, therefore according to the classification of GOST 12.1.007-76 the preparation Imkar-120 should be classified as hazard class III by injection into the stomach – substances are moderately dangerous.
