In animals pre hair clip out on the site back 2x2 cm in rats, 5x5 cm in rabbits. Rats appliques make in the direction from the rear third of the back towards the head, the rabbits in the direction from the neck to the tail. The experimental rats divided in different quantities in 8 groups. The first three groups on the surface of the skin is applied and rubbed in once, respectively, 0,25%, 0,5%, 1% suspension within 15 days; the second three groups - twice a day during the same time. Control groups according to the same scheme used diluent (distilled water) with an emulsifier. All the animals put on the same skin area 10-30 at allow dose mixture III in the same concentrations.Experienced rabbit clip out two skin area on both sides of the spine, treated with 70% alcohol and put a scarificator scratches. Then on one side put a 0.01% solution of histamine hydrochloride, and the other respectively of the investigated concentration of 0.25%, 0.5% and 1% suspension of the mixture III.Monitor the condition of the skin of animals carried out in 30 min, 24 hour, 48 hour and 72 hour (take into account the emergence of eritem, infiltration, ulceration, necrosis of tissue. The research results are summarized in table. 6 and 7.IV. The study of resorptive action.The study of resorptive action of a mixture of III (Y. I. Kundiev. Methods study resorptive action of chemical substances. In the book: Methods for determining the toxicity and hazards of chemicals. M.: Medicine, 1970. -S. 275-281). The reaction of rats studied in concentrations of 0.25%; and 0.50% and 1.00% by hour exposure of rats tail in test tubes with suspension III at a temperature of 28oC. Tails control animals are placed in a test tube with water and surfactant. All tubes are in a water bath. About skin-resorptive effect III judged by daily monitoring the physiological condition of rats for 14 days.V. Learning bride is a Finance test sub-chronic toxicity (Lim, R. K., Rink K. G., Qlass H. G. , Soaje-Echaque E. Arch. Intern. Pharm. Therapie. 1961, Vol. 130, NOS 3-4. -P. 336). The mixture in the third dose from a previously installed a single LD50(component 0,1) cause cutaneous animals of the experimental group the first 4 days. Then every subsequent 4 days, the dose (III increase in 1,5 times and put the animal. The duration of the experience of 244 days. By the end of the experience caused dose of 8.5 LD50. Evaluate the results of the study in relation to the average effective doses of acute and subacute actions. During the experience of watching animals, consider: status (agitation, depression), the nature and degree of activity and coordination, reaction of the animal to approximate, tactile and painful stimuli, the presence of tremor, convulsions, paresis, paralysis, discharge from the eyes, nose, skin discoloration, change in body weight, food anxiety.See Toxicological studies have shown that a mixture of 4-nitro - and 6-nitro-5,7-dichlorobenzophenone (III) has the following parameters toxicity (table. 4).When applied once on the skin to experimental rats a mixture of (III) at doses of 500, 1000, 2500 and 5000 mg/kg did not cause death of the animals.The obtained data allow us to classify the studied mixture (III) to the third class umenie (GOST 12.1.007-76- "Harmful substances. Classification and General safety requirements").As can be seen from the obtained data table. 5, the mixture of (III) at concentrations of 0.25%, 0.50% and 1.00 m% does not affect the skin irritant and does not alter the physiological condition of the rats.The study of the allergenic properties of the mixture (III) showed the absence of contact dermatitis in rats from concentrations of 0.25 to 1.00%. The skin of the rats remained within 72 hours smooth and shiny. Indication of the strength of allergen exposure, in addition to local skin reactions, is a common reaction of the body, manifested in the increase in the number of eosinophils in the peripheral blood.As can be seen from the table. 6 and 7, even 30% concentration of the mixture of (III) did not cause an increase in the number of eosinophils in peripheral blood and remained at the level benchmarks. The number of erythrocytes and leukocytes, hemoglobin remain within the normal range of control from the application of 5 and 10% concentrations III.In the experiments on determination of reaction rabbits in response to 0,25-0,50% concentration of the mixture III was not observed reaction. After application of 1% concentration III after 24 hours there was little roller (compaction) during the scratches that after 24 hours it had disappeared.Posted islamocracy III up to 1% may cause a minor reaction of the body.As shown by the results on the study of resorptive action of the investigated mixture III at concentrations of 0.25, 0.50 and 1% did not have any toxic effect on the physiological condition of the animals. The leather tails are not marked swelling, redness, peeling, subcutaneous infiltration, destructive phenomena.A single cutaneous application of a mixture of III even at a dose of 5000 mg/kg did not cause death in rats. Local action was characterized by redness, peeling skin and loss of hair.In the experiments on determination of the cumulative properties of the mixture III when applied to skin, failed to cause the death of a single rat, although each animal received III total dose 3813 mg/kgThus, a mixture of 4-nitro and 6-nitro-5,7-dichlorobenzophenone III in the investigated concentrations and doses not have an irritating, allergenic, skin-resorptive and cumulative effect.EXAMPLE 6. A study of genotoxic mixture of 4-nitro and 6-nitro-5,7-dichlorobenzophenone (nitroxane).Evaluation of the mutagenic activity were carried out using the Ames test. The Ames test will provide an opportunity to investigate the mutagenicity as the source of the drug and its metabolites.Metabolic preferably, derived from liver cells of rats pre-treated monooxygenase inducers of mixed fractions.The drug solution is prepared in dimethyl sulfoxide at standard concentrations (1, 10, 100, 1000 and 10000 µg/ml). A preliminary stage to assess mutagenicity is the determination of the toxicity of the drug in relation to testory strains to exclude the possibility of obtaining false-negative results.In a test tube with 3 ml of cold 0.6% of mycopathologia agar (MPA) add 0.1 ml of bacterial suspension of the desired dilution and 0.1 ml of the substance in the tested concentration. The solution is stirred and layer on the bottom 2% nutrient agar in a Petri dish. In the negative control instead of matter add 0.1 ml of solvent. After 24 hour incubation at 37oC count the number of colonies in the experiment and control and calculate the percentage of survival or toxicity of the substance.< / BR>To evaluate the mutagenicity of the drug in paleobotany of 0.6% top agar contribute 0.1 ml of bacterial suspension, 0.1 ml of tested compound, 0.5 ml of microsome activating mixture (MAC) containing cofactors, and in the case of evaluation of mutagenic activity of metabolites distilled water (incomplete MAC) for OTS who CLASS="ptx2">Semisolid agar should cover the bottom surface of minimal agar smooth thin layer. A Cup of leave at room temperature for 30-40 min and after solidification is transferred in a thermostat at 37oC. experience also put negative and positive control.In the negative control in the upper layer of agar together with a suspension of bacteria also add a complete (or incomplete) MAC and 0.1 ml of solvent. As positive controls using known drugs, for showing mutagenic effects in the same modifications experience with metabolic activation or without it.Without metabolic activation usually use nitrozometilmochevinu (100 μg/ml) for TA 1535 and TA 100 and nitrosoguanidine (5 μg/ml) for TA 1538 and TA 98. With metabolic activation of cyclophosphamide (100 mg/ml) for TA 100; 2 aminofluorene (30 µg/ml) - AND TA 98. Analysis carried out after 48 h of incubation. Compare the number of colonies - revertants in the experiment and the control.Used Salmonella typhimurium strains TA 98 and TA 100, taking into account respectively mutations Tina shift of the reading frame and replacement of base pairs. Metabolic activation simulating the transformation of compounds in mammals, carried/P> Each value represents the average of three replicates, with standard deviation does not exceed 5%.Nitroxane at concentrations of 100 µg/bowls and 1000 µg/bowls completely inhibited the growth testinig bacteria, therefore, for further research in the Ames test we used the following concentration ranges: 0,1, 1, 10 ág/vial.The results of studies of the drug on the mutagenic activity in the test Salmonella/microsome assay are presented in table. 9.From the data presented in table. 9, it follows that the studied compound in this range of concentrations is not mutagenic activity in the Ames test without metabolic activation. However, metabolic activation in vitro microsome activating composition on the basis of microsome fractions of rat liver lead to an increase in genotoxic activity of the study drug. Nitroxane at a concentration of 10 µg/bowls causes almost 8-fold excess (7.84 times in strain TA 98 and 7.8 times in strain TA 100) above the spontaneous background mutation engine.Thus, nitroxane is promutagens - shows a weak mutagenic effect in the presence of enzymes microsome fraction mammals.Therefore, the composition of in in the Russian form of rubromycosis the hands and feet, not have an irritating, allergenic, skin-resorptive, cumulative and mutagenic action. Composition for the treatment of this form may be accompanied shape rubromycosis feet and hands, caused by the fungus Trichophyton rubrum, containing the active substance - nitrosoaniline and a diluent, wherein the active substance composition contains a mixture of 4-nitro - and 6-nitro-5,7-dichlorobenzophenone when the ratio of these components 30 : 70 respectively, and the diluent is a mixture of polyethylene glycol and dimethyl sulfoxide, in the following ratio, wt.%:
