Introduction. Capillary changes link are closely correlated with shifts in central hemodynamics, which allows the use of microcirculation parameters as diagnostic and prognostic criteria for assessing the body as a whole. The work is aimed at increasing the efficiency of detecting microcirculatory disorders by computer capillaroscopy in patients with pathology of intranasal structures and accompanied by difficulty in nasal breathing and smell. Purpose: nature and severity analysis of intravital morphological changes in the microvessels of the nail bed in patients with pathology of the intranasal structures, accompanied by impaired nasal breathing and smell.Materials and methods: We examined 145 patients aged 18–38 years who were diagnosed with changes in intranasal structures with varying degrees of nasal obstruction and impaired sense of smell. Patients were divided into 3 groups. The first group — patients with a disease duration of 3–5 years; the second group — patients with a disease duration of up to 0.5 years; the third group — patients with a disease duration of up to 1 month. Results: Patients with intranasal structures pathology in the I and III clinical groups with a duration of nasal obstruction up to 5 years and 1 month. Changes in systemic microcirculation were significantly more frequently observed than in patients with a disease duration of up to 0.5 years. The observed tendency to disturbance of microcirculation in groups III and I is caused, first of all, by a change in the state of microvessels for sharp hypoxia (these changes are consistent with rhinomanometry) and a “breakdown” of adaptation mechanisms in the group of prolonged nasal obstruction for up to 5 years, at that time as in group II, there is an increase in the reserve of adaptation from the cardiovascular system to the conditions of nasal obstruction. Сonclusions: The study of microcirculation using capillaroscopy made it possible to study the smallest vessels, capillaries, which are the first to respond to impaired nasal breathing by changing the functional state and morphological reconstruction of the microvasculature of the bloodstream.
介绍。毛细血管变化与中心血流动力学的变化密切相关,这使得微循环参数可以作为评估整个身体的诊断和预后标准。本研究旨在提高计算机毛细管镜对鼻内结构病变伴鼻呼吸和嗅觉困难患者微循环疾病的检测效率。目的:分析鼻内结构病变伴鼻呼吸、嗅觉功能障碍的甲侧微血管活体形态学改变的性质及严重程度。材料和方法:我们检查了145例年龄在18-38岁之间的患者,他们被诊断为鼻内结构改变,不同程度的鼻塞和嗅觉受损。患者分为3组。第一组-病程3-5年的患者;第二组——病程长达0.5年的患者;第三组-病程长达1个月的患者。结果:I、III临床组患者鼻内结构病理,鼻塞持续时间达5年零1个月。与疾病持续时间长达0.5年的患者相比,系统性微循环的变化明显更频繁。在III组和I组中观察到的微循环紊乱的趋势,首先是由于微血管状态的变化(这些变化与鼻测压一致)和长期鼻塞长达5年的适应机制的“崩溃”,此时与II组一样,心血管系统对鼻塞状况的适应储备有所增加。Сonclusions:使用毛细血管镜研究微循环使研究最小的血管毛细血管成为可能,毛细血管是第一个通过改变血液微血管的功能状态和形态重建来对鼻腔呼吸受损做出反应的血管。

Introduction. Оpen wounds and ulcers treatment involves the use of bandage material, antibiotics and antiseptic to prevent the development of a pathogenic microflora and to provide the necessary conditions for tissue regeneration. An emergence of multi-resistant strains of microorganisms reduces the effectiveness of such technology and requires the new treatment approaches. One of the promising areas is a photodynamic therapy with the use of external photosensitizers. The aim of the investigation is to determine the effectiveness of the synergistic action of red light (660 nm) and different concentrations of methylene blue on the inhibition of Staphylococcus aureus growth. Materials and methods. We used the hydrogels based on the copolymers dextran-polyacrylamide with the different concentration of crosslinking agent 0.2 %, 0.4 %, 0.6 % (w/w) for investigation a rate of diffusion methylene blue into and out from hydrogel. Microbiological research was performed on wild strains of S. aureus isolated on a Yolk-salt agar. The evaluation of a bactericidal action of methylene blue was carried out on a Müller-Hinton No. 2 agar similarly to the disc-diffusion method for assessing the resistance of microorganisms to antibiotics. For irradiation by different wavelengths was used «LIKA-Led» (Photonics Plus) LEDs 390 nm, 460 nm and 660 nm. The radiation power for each wavelength was 100 mW, duration — 20 min, 30 min, 40 min. According to the duration, the irradiation doses were 21 J/cm2, 31.5 J/cm2, 42.1 J/cm2. Mathematical and statistical data processing was performed in the OriginLab 8.0 software package. Results. Increasing the amount of crosslinking agent in the hydrogel based on the copolymer dextran-polyacrylamide provides a decrease in the diffusion rate of methylene blue from the hydrogel. 390 nm ultraviolet radiation reduces the number of S. aureus colonies for 80% at 20 min exposure. Further increase in the exposure did not contribute to significant changes in this indicator. Blue light (460 nm) reduces the presence of this strain of microorganisms for 66% at 20 min exposure and reaches the effect of UV at 30 min exposure. Red light (660 nm) has no bactericidal effect. Minimal activity was found for methylene blue at concentrations of 0.001% and 0.0001% which was around 6 mm. The synergistic effect of 0.001% methylene blue and red light increases the activity for 40% up to 10 mm. Conclusions. For the photoinactivation of Staphylococcus aureus, it is advisable to use a low energy red light with a 660 nm wavelength in combination with a saturated methylene blue (0.001%) hydrogels. Perhaps the synergistic action of red light and dye provides a generation of active radicals that contribute to the growth retardation of microorganisms.
介绍。Оpen伤口和溃疡的治疗包括使用绷带材料、抗生素和防腐剂,以防止致病性微生物群的发展,并为组织再生提供必要的条件。多重耐药菌株的出现降低了这种技术的有效性,需要新的治疗方法。其中一个有前途的领域是使用外部光敏剂的光动力疗法。本研究的目的是确定红光(660 nm)和不同浓度亚甲基蓝协同作用对金黄色葡萄球菌生长的抑制效果。材料和方法。以右旋糖酐-聚丙烯酰胺共聚物为基础,在交联剂浓度为0.2%、0.4%、0.6% (w/w)的情况下制备水凝胶,考察了亚甲基蓝在水凝胶中的扩散速率。对金黄色葡萄球菌野生菌株在蛋黄盐琼脂上进行了微生物学研究。在 ller- hinton 2号琼脂上评价亚甲基蓝的杀菌作用,类似于评估微生物对抗生素耐药性的圆盘扩散法。对于不同波长的照射,使用«LIKA-Led»(Photonics Plus) led 390 nm,460 nm和660 nm。每个波长的辐射功率为100 mW,持续时间为- 20 min、30 min、40 min,照射剂量根据持续时间分别为21 J/cm2、31.5 J/cm2、42.1 J/cm2。在OriginLab 8.0软件包中对数据进行数理统计处理。在基于葡聚糖-聚丙烯酰胺共聚物的水凝胶中增加交联剂的量可以降低亚甲基蓝从水凝胶中的扩散速率。390 nm紫外线照射20分钟可使金黄色葡萄球菌菌落数量减少80%。暴露量的进一步增加并没有导致该指标的显著变化。蓝光(460 nm)在20分钟的曝光下可将该菌株的存在减少66%,并在30分钟的曝光下达到紫外线的效果。红光(660 nm)无杀菌作用。在浓度为0.001%和0.0001%时,亚甲蓝的活性最小,约为6毫米。0.001%亚甲基蓝与红光协同作用可使活性提高40%,达10 mm。对于金黄色葡萄球菌的光灭活,建议使用660 nm波长的低能量红光与饱和亚甲基蓝(0.001%)水凝胶结合使用。也许红光和染料的协同作用提供了一代活性自由基,有助于微生物的生长。

Since the first demonstration of a tissue and organ transilluminator by a graduate of the Kyiv University V.A. Milliot at the 1867 exhibition in Paris, many enthusiasts have dealt with this diagnostic method. This paper provides an overview of publications from the funds of the Kharkiv Medical Library, materials from the Internet about the “transillumination” method, about Moshe Zelmanovich Sigal, educated at Donetsk Medical Institute, his life path, predecessors and followers. Studies in transmitted light are based on the differences in the absorption of light by various structures of the body. Transillumination attracts with the possibility of its use during operations. Depending on the relative position of the light source, the object being studied, and the researcher, three types of transillumination are possible: 1) intracavitary — the light source is inserted into the organ cavity; 2) transorgan — the light source is located behind the organ; and 3) extracavitary — transillumination is performed from the outside into the hollow organ when the imaging is made using an optical device inserted into the organ cavity. Inflation of a cavity increases the transparency of its walls and allows identifying subtler structures of the body. Based on transillumination angioscopy, M.Z. Sigal a half century ago developed a technique for lifetime monitoring of blood flow through the intramural vessels of the walls of hollow organs. Due to the difference in the color of blood in the vessels, the veins produce more intense shadow images than the arteries during transillumination. Transillumination angioscopy is possible without contrast agents. The development of technical means, the emergence of new light sources and its transportation allow modern surgeons to guide the course of the operation until the last suture using transillumination.
自从基辅大学的一名毕业生首次展示组织和器官透光器以来。在1867年米略特在巴黎的展览会上,许多爱好者都处理过这种诊断方法。本文概述了哈尔科夫医学图书馆的出版物、互联网上关于“透视”方法的资料、在顿涅茨克医学研究所接受教育的Moshe Zelmanovich Sigal、他的人生道路、前辈和追随者。对透射光的研究是基于人体不同结构对光吸收的差异。透光照明因其在操作中使用的可能性而吸引人。根据光源、被研究对象和研究人员的相对位置,有三种类型的透照是可能的:1)腔内-光源插入器官腔;2)跨器官——光源位于器官的后面;当使用插入器官腔内的光学装置进行成像时,从外部到中空器官进行透照。腔体的膨胀增加了腔壁的透明度,并允许识别身体的微妙结构。半个世纪前,M.Z. signal在透照血管镜的基础上,开发了一种终生监测通过中空器官壁内血管的血流的技术。由于血管中血液的颜色不同,在透照过程中,静脉比动脉产生更强烈的阴影图像。无造影剂的透照血管镜检查也是可行的。技术手段的发展,新光源的出现及其运输使现代外科医生能够使用透照来指导手术过程,直到最后一次缝合。

Thermal processes during local laser heating of biological tissues 局部激光加热生物组织时的热过程

Introduction. Lasers in medicine are currently widely used for both diagnosis and treatment. Studies of the thermal processes that occur when a person is exposed to laser radiation have made it possible to developinnovative methods of treating many diseases. Purpose: to study thermal processes in biological tissues during their local laser heating (mathematical model and experiment). Materials and methods. Using the developed mathematical model of the process of local heating of a certain region inside biological tissue, we studied the process of heating the environment by continuous and pulsed laser radiation using infrared light with a wavelength of 0.98 μm, red light with a wavelength of 0.65 μm, green light with a wavelength 0.5 microns and blue light with a wavelength of 0.435 microns. Results. The sizes of the heated region, the time of establishment and decrease in temperature are determined. The calculation results are in good agreement with the obtained experimental data. Findings. The mode of heating biological tissue with laser radiation depends on the wavelength. The maximum heating temperature of the irradiated section with a radiation pulse duration much shorter than the thermal time constant is independent of the shape and duration of the pulse and is determined only by the energy of the absorbed radiation. The distribution of heat into the medium during the duration of the pulse is determined by its duration and thermal diffusivity of the tissue. To reduce the heating of the surrounding tissue, it is necessary to use short radiation pulses. The progress of tissue heating by a sequence of radiation pulses depends on the relationship between the duration of the pulses, the period of their repetition, and the thermal time constant of the medium. The average (smoothed) temperature is the same as when heated with continuous power equal to the average power of the pulse-modulated radiation.
介绍。激光目前在医学上广泛用于诊断和治疗。对人暴露于激光辐射时所发生的热过程的研究,使开发治疗许多疾病的创新方法成为可能。目的:研究生物组织局部激光加热过程中的热过程(数学模型和实验)。材料和方法。利用建立的生物组织内某一区域局部加热过程的数学模型,研究了波长为0.98 μm的红外光、波长为0.65 μm的红光、波长为0.5微米的绿光和波长为0.435微米的蓝光对环境进行连续脉冲激光加热的过程。确定了加热区域的大小、建立时间和温度下降。计算结果与实测数据吻合较好。用激光辐射加热生物组织的方式取决于波长。当辐射脉冲持续时间远短于热时间常数时,辐射截面的最高加热温度与脉冲的形状和持续时间无关,仅由吸收辐射的能量决定。在脉冲持续时间内热量在介质中的分布是由脉冲持续时间和组织的热扩散率决定的。为了减少对周围组织的加热,有必要使用短辐射脉冲。一系列辐射脉冲对组织加热的过程取决于脉冲持续时间、脉冲重复周期和介质热时间常数之间的关系。平均(平滑)温度与连续加热功率等于脉冲调制辐射的平均功率时的温度相同。

Lasers in medicine are currently widely used for both diagnosis and treatment. Studies of the thermal processes that occur when a person is exposed to laser radiation have made it possible to developinnovative methods of treating many diseases. Purpose: to study thermal processes in biological tissues during their local laser heating (mathematical model and experiment). Materials and methods. Using the developed mathematical model of the process of local heating of a certain region inside biological tissue, we studied the process of heating the environment by continuous and pulsed laser radiation using infrared light with a wavelength of 0.98 μm, red light with a wavelength of 0.65 μm, green light with a wavelength 0.5 microns and blue light with a wavelength of 0.435 microns. Results. The sizes of the heated region, the time of establishment and decrease in temperature are determined. The calculation results are in good agreement with the obtained experimental data. Findings. The mode of heating biological tissue with laser radiation depends on the wavelength. The maximum heating temperature of the irradiated section with a radiation pulse duration much shorter than the thermal time constant is independent of the shape and duration of the pulse and is determined only by the energy of the absorbed radiation. The distribution of heat into the medium during the duration of the pulse is determined by its duration and thermal diffusivity of the tissue. To reduce the heating of the surrounding tissue, it is necessary to use short radiation pulses. The progress of tissue heating by a sequence of radiation pulses depends on the relationship between the duration of the pulses, the period of their repetition, and the thermal time constant of the medium. The average (smoothed) temperature is the same as when heated with continuous power equal to the average power of the pulse-modulated radiation.","PeriodicalId":33499,"journal":{"name":"Fotobiologiia ta fotomeditsina","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69000867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article presents the results of application of photochemotherapy in the complex rehabilitation process of patients with bronchial asthma (hereinafter — BA). The assessment of effectiveness and impact was made on the basis of changes in indicators of blood rheology as one of the pathogenesis of this disease and based on clinical indicators of the flow BA. It is established that in comparison with the results of the baseline treatment (42 patients) in 74 patients with BA under the influence of photochemotherapy occurs a statistically significant restoration of the altered rheological parameters and improves the clinical course of BA. The effect of optical radiation of blue and red lights on the clinical course of BA in comparison with conventional medication is more pronounced, almost the same criteria of treatment efficacy, but differ in their mechanism of effects on the body.
