 The goal: to increase the effectiveness of far long-wave ultraviolet therapy in patients with lichen planus using immersion agents. Materials and Methods. The study included 50 patients aged from 18 to 65 years with typical and hypertrophic forms of lichen planus who had received UVA1-therapy. All the patients were divided into 2 groups: in the 1-st group before the phototherapy on the elements of lichen planus caused an clearing agent propylene glycol (PG) and in the 2nd group PG was not used. The dynamics of the enlightenment of the skin was assessed using optical coherence tomography. After the end of treatment was a decrease in mean group values of ILP 96% of the original value, pruritic index 98%, DLQI 87% respectively. Results. In the 1-st group patients occurred more rapid resolution of the pathological process, the rate of phototherapy was 15-20 procedures. In the 2nd group to complete resolution of the pathological process, required an increase in the number of procedures to 20-25. Conclusion. Far long-wave UV therapy showed high efficacy and compliance in patients with lichen planus, the use of the 1,2-PG allowed to shorten the duration of treatment of patients.

Objective; to choose the optical clearing agent with the best illuminating ability in the long-wave UV spectrum used in phototherapy. Material and methods. Ex vivo skin samples were used as objects of study. Measurement of the total transmission spectra of the skin sections was carried out on a multi-channel spectrometer Ocean Optics QE 65000 (Ocean Optics, USA) using 4 optical clearing agents (40% glucose solution, glycerol, propylene glycol, oleic acid).
Results. Having conducted a comparative analysis of ex vivo data collected from spectroscopy of these optical clearing agents at a wavelength of 370 nm, it was found that the maximum optical clearing was achieved using propylene glycol at 44 minutes, which was 11.56%. Conclusion. The use of optical clearing agents is possible not only to improve the visualization of the skin structure, but also to explore the dynamics of light transmission in long-wave UV A-1 therapy of patients.

Aim: working out the methods of visualization of information obtained during optical coherent tomography in normal skin and in series of inflammatory disorders. Materials and Methods. OCS1300SS (made in Thorlabs, USA) was used in which the source of emission of radiation was a super-luminiscent diode with mean wavelength of 1325 nm. 12 patients with different skin conditions and 5 virtually healthy volunteers were examined with ОСТ procedure in OPD and IPD settings. High resolution USG numerical system DUB (TPM GmbH, Germany) was used for comparative USG assessment. Results. ОСТ demonstrated considerably more detailed picture of the objects scanned compared to USG investigation. Image obtained with the help of ОСТ contains vital information about sizes of macro-morphological elements, status of vascular elements and their density in different depths of the skin. Conclusion. Additional results obtained from ОСТ of the skin lesions in plane section improves attraction for ОСТ in practical dermatology.

The goal: to investigate the process of angiogenesis by determining the level of vascular endothelial growth factor (VEGF) in the blood serum of patients with lichen planus (CPL) and psoriasis. Material and Methods. The study included 50 patients with CPL, 62 patients with psoriasis and 36 were in the control group of healthy individuals. All of the participants were to determine the level of VEGF in a blood serum before treatment. Results. Patients with CPL had an increase in the level of VEGF in serum prior to 1992 pg/ml, in the patients with psoriasis — up to 1748.8 pg/ml. Level of VEGF in healthy individuals ranged from 37 to 475 pg/ml. Conclusion. When the CPL and psoriasis excessive angiogenesis is observed, elevated levels of VEGF in the serum of these patients and it is possible that vascular normalization such element of pathogenesis of psoriasis and CPL lead to stable remission of these dermatoses.
