Study of biological activity

Acute toxicity intraperitoneal injection was determined by nonlinear white mice-males weighing 18-24 g test substance and the reference product was administered into the abdominal cavity in the form of a solution in 1%starch mucus at a rate of 0.1 ml / 10 g weight of the animal in increasing doses. The results were processed by Prozorovsky calculation of the median lethal dose (LD50) at P<0,05 [Prozorovsky CENTURIES, Prozorovsky BTW, Demchenko V.M. Pharmacol. toxicol., v.41, №4, s-502 (1978)].

The study of connections for local anesthetic activity. In the experience used generalizirovanny rabbits (males) weighing 2.0 to 2.5 kg were Determined sensitivity threshold of the cornea of the rabbit to tactile impact. The original sensitivity of the cornea of the rabbit (control) was measured twice with an interval of 5 minutes. A solution of the substance in a volume of 0.4 ml was injected into the conjunctival SAC of the eye of the rabbit for 2 times, with an interval of 30 seconds. Each concentration was tested 8 times, using the cornea different eyes. Determined index Rainier characterizing the depth of surface anesthesia and represent the sum of the mechanical stimulation of the cornea within the hour, and the duration of anesthesia in minutes.

Determination of the bacteriostatic activity was performed by the method of twofold serial dilutions in liquid nutrient medium [Manual on experimental (preclinical) study of new pharmacological substances. - M., 2000, s-273]. For all the studied compounds were determined IPC in respect of pharmacopoeial strains: S. aureus ATCC 6538-P, E. coli ATCC 25922, .albicans ATCC 885-653. Crops produced in mesopotania broth, pH 7.0 with different concentrations of the tested compounds. The cultures were grown in test tubes on a beveled apparitional environment (mastopathy agar solid medium Saburo). To determine the antimicrobial activity was used 18-20-48-hour culture of microorganisms. For preparation of the working suspension of microbes produced washout grown culture isotonic sodium chloride solution, and set the density of the microbial suspension according to the turbidity standard 5 units. Next, from the obtained microbial suspension (500 million M.L./ml) were prepared working solution of bacteria with a concentration of 5 million M.L./ml of This suspension of microbes was made in the amount of 0.1 ml in tubes with serial dilutions of study drug. Thus, microbial load, the lubricant when determining the ACA was 250000 M.L./ml The target compound in the amount of 0.05 g was dissolved in 5 ml of DMSO, 1 ml of the prepared dilution of 1:100 was combined with 4 ml mycopathologia broth or liquid Saburo (1:500). Next was preparing a series of serial dilutions of the compounds twice with decreasing concentration.

Records of the results produced after 18-20 hours of exposure control and experimental tubes in the incubator at 37°C for bacteria and 48 hours at 22°C for fungi. Minimal inhibitory concentration (MIC) was determined by the absence of signs of growth on nutrient medium: the last tube of stunting (clear broth) corresponds to the IPC of the drug in relation to this strain. Bacteriostatic effect of the studied compounds was compared with the action dioksidina [Padalka E.N. Infection and antimicrobial therapy, 2001, Vol.3, No. 5, p.150-155], turisticheskiy - fluconazole [Rex J.Y., Walsh T.J., J. Sobel d/ et all, Clin. Infect. Dis., 2000, v.30, No.4, R-678].

A line marked in the middle is drawn from behind through a lower edge of an ischial bone and an upper edge of a wing of ilium. A line transversal to a longitudinal axis of a body is drawn through the mark and extended on a gluteal skin. Thereafter, from one side through a projection of a centre of the lower edge of the ischial bone and the upper edge of the wing of ilium, a second line is drawn, and its intersection with the line drawn transversally to the longitudinal axis of the body on skin is dotted to trace a needle therethrough into tissues in a frontal plane perpendicularly to a sagittal plane. Thereafter, a medicinal solution containing 60 ml of 0.25 % novocaine and 10 mg of vitamin B12 is injected with 0.2 mg of dexamethasone added per each 1 ml of the administered solution.

EFFECT: higher efficacy of the block of the superior gluteal nerve due to more precise drug delivery thereto.

FIELD: medicine.

SUBSTANCE: invention refers to medicine, and can be used if extremity vein catheterisation is required for multiple intravenous introduction of drug solutions. That is ensured by vein catheterisation followed by change of an extremity position with respect to a patient's trunk so that an open pavilion of the catheter is arranged below a level of a patient's right atrium. An infrared imager is used to monitor an extremity surface condition within a projection of the catheter. If observing a region of local hyperthermia along the vein, its content is examined by ultrasound. A thrombus if any is sized up; tourniquets are applied below and above the region of local hyperthermia to complete sanguimotion cessation in the vein. Then, blood is taken from the vein to its devastation, and the volume of taken blood portion is measured that is followed by introduction of 2% lidocaine hydrochloride 0.5 ml and a thrombolytic solution at temperature +42°C in the volume necessary for complete vein filling. 3 minutes later, the whole liquid vein content is removed through the catheter, and the tourniquets are released, the vein content is examined by ultrasound. The presence of a thrombus requires another 3-minute tourniquet application with venous blood replacement by a local anaesthetic solution with a thrombolytic agent to stabilise thrombus size, then the catheter is removed, and the drugs are introduced by means of another catheter which is inserted in another extremity vein.

EFFECT: method allows higher safety and effectiveness of vein catheterisation due to early phlebitis detection and exact delivery of fibrinolytic agents to the thrombus to dissolve a "fresh" portion of the thrombus that allows reducing a risk of thromboembolism.
