Title: Method for producing immobilized enzyme preparation based on collagenase, hyaluronic acid and polysaccharides modified with vinyl monomers
Inventor: Kholyavka Marina Gennadevna
IPC: C12N11/08
Filed: 2020-07-27
Granted: 2021-06-28
Abstract: FIELD: chemical and pharmaceutical industry; medicine. 
     SUBSTANCE: present invention relates to the field of chemical and pharmaceutical industry and medicine, namely, to a method for producing an immobilized enzyme preparation based on collagenase, polysaccharides modified with vinyl monomers, and hyaluronic acid. The method includes the dissolution of collagenase in an aqueous solution of low-molecular-weight hyaluronic acid 300 kDa or medium-molecular-weight hyaluronic acid 500 kDa or high-molecular-weight hyaluronic acid 800 kDa in a ratio of 10 mg of collagenase per 2 ml of an aqueous solution of low-molecular-weight hyaluronic acid 300 kDa or medium-molecular-weight hyaluronic acid 500 kDa or high-molecular-weight hyaluronic acid 800 kDa at a concentration of 1.5%. Mixing is carried out until complete dissolving at room temperature. Collagenase is then immobilized by adding to the resulting mixture of a graft copolymer of carboxymethylcellulose 50-100 kDa (CMC) or chitosan 50-100 kDa (CHTS) with N-vinylimidazole (VI) or N,N-dimethylaminoethylmethacrylate (DMAEMA) in an amount of 100 to 290 mg to obtain a liquid preparation or 300 to 500 mg to obtain a gel. Due to the invention, collagenase solutions can be stored at temperatures from 4 to 25℃ for 21 days, and the enzyme becomes more stable in comparison with the native one and it is able to penetrate into the deep layers of the skin. The introduction of modified polysaccharides into the composition of the preparation allows not only to vary the viscosity and consistency of the samples (from the liquid state to the gel with different fluidity), but also promotes the formation of conjugates with an enzyme with a large number of bonds and interactions between the polysaccharide and the enzyme, compared with unmodified carboxymethylcellulose and chitosan. This further increases the stability of the preparation and the concentration of the active substance in the affected area of the skin, and provides a controlled (portion) release of collagenase, maintaining its necessary concentration for a long time. 
     EFFECT: technical result is an increase in the stability of the preparation.

Abstract: FIELD: medicine; pediatrics; cardiology; sports medicine. 
     SUBSTANCE: invention relates to medicine, pediatrics, cardiology and sports medicine; it can be used to increase the heart rate in young athletes with sinus bradycardia (heart rate less than 60 beats/min) for an adequate assessment of the corrected QT interval (QTc) using the Bazett formula, when detecting a latent prolongation of QT interval on the ECG in athletes, underestimated in view of sinus bradycardia. After a 5-minute rest, 12-channel ECG is taken at rest, when sinus bradycardia (heart rate less than 60 beats/min) is detected, without changing the body position, a test with isometric exercises is carried out - work with a wrist expander to increase heart rate. For the test, a wrist expander with a set compression force (20 kg) is used for rhythmic compression of the expander with a dominant hand, lasting from 20 to 30 seconds until a heart rate of 60 beats/min or more is reached. After that, 12-channel ECG is recorded again, heart rate, QT interval (QTc) are assessed. QTc interval is assessed in the II standard lead (in case of interference - in the V5 lead).  
     EFFECT: method provides increased accuracy of detecting latent prolongation of QT interval on the ECG in athletes.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to rehabilitation, and can be used to form a phantom hand map. Sensitivity is determined on the skin of the stump using the installed electroencephalographic electrodes by means of stimulation with bipolar current pulses of 100–300 ms with frequency of 3–5 Hz. Intensity is selected individually 3–4 times higher than the level of the patient’s sensory threshold. 300–500 simulations are presented successively on each of the external, internal, front and back surfaces of the hand stump. Somatosensory evoked potential is obtained by averaging the obtained electroencephalographic activity. Maximum amplitude of the cortical responses is used to determine the location of the complex of electromechanical devices. Tactile sensitivity of the phantom hand map is trained by means of virtual reality glasses which demonstrate a virtual limb to the patient. Also used is complex of 6 electromechanical devices installed in accordance with five fingers and one device for palmar surface, optical tracker and stereo camera. Motions of the virtual and physical hands are compared to form an illusion of an intact limb and possibility of its movement. Fingers and palmar surface of the virtual hand are touched by objects which cause activation of tactile sensitivity in the physical world. Duration of one lesson is from 30 to 50 minutes, once a day. 
     EFFECT: method provides formation of a phantom map on the skin of the hand, touching which causes tactile sensations, which are identical to sensations when touching separate fingers with an intact hand.
