The linearity with r2 =0.999 was found to be at 313±1 nm for 4–10 µg/ml solution in glycerin – water (5%, w:v) with prior dilution of substance in 96% ethanol with heating. <...> The minimal measurement limit was found to be 0.3316 µg/ml, and the minimal quality determination measurement limit was 1.0050 µg/ml. The method was validated for linearity, accuracy, precision, range, ruggedness and robustness. <...> Метод был проверен на линейность, правильность, прецизионность, диапазон применения, точность и робастность. <...> When administered intragastrically its LD50 colі, Bacillus subtilis and Salmonella cholera with minimum bactericidal concentration (MBC) of 15.6–31.25 μg/ml [6]. <...> Against Staphilococcus aureus and Proteus vulgaris MBC was 62.5 μg/ml, and Pseudomonas aeruginosa was the most resistant with MBC of 125.0 μg/ml. It was also said, that it was active against colibacteriosis pathogens: minimum inhibition concentration (MIC) against E. coli 08 and A20 was 7.8 μg/ml, and against E. coli 0142(p) and 078 – 15.6 μg/ml [7]. <...> Thus, it was advised to apply Cipisept-o for 5–7 consecutive days at a dosage of 0.5–1 ml/kg of body weight to prevent and treat the colibacteriosis and salmonella of pigs and calves [4, 7]. <...> Ciminalum demonstrated MIC ≥50 µM against diff erent Vibrio strains and completely inhibited AI-2-regulated bioluminescence of V. harveyi BB170 in 100 µM by decreasing the DNA-binding ability of the quorum-sensing regulator LuxR [8]. 154 "Recipe", 2017, volume 20, № 2 class of danger was Научные исследования Besides, there were found composition of periodontal fi lms to be used in dentistry, which were theoretically justifi ed and experimentally confi rmed to have antibacterial properties in treatment of patients with periodontitis and gingivitis [9]. <...> It contained PEO – 400 (2.5%), DMSO (2.5%), glycerin (2.5%), sodium carboxymethyl cellulose (3%), ciminalum (5%) and distilled water up to 100 ml. Facing wound-healing eff ect for dogs, it had 100% of healing by the 17th day against 30 <...>
