The Efficacy of the Comprehensive Use of Naphthalan and Non-Selective Chromotherapy in the Treatment of Patients with Gonarthrosis.

In the last decade, a new direction of phototherapy - the non-selective chromotherapy (NSC) with Bioptron - has become widespread in clinical physiotherapy. The aim of the study was the scientific justification of the comprehensive treatment of patients with osteoarthritis of knee joints, including the combined use of refined naphthalan applications and irradiation with incoherent polarized Bioptron light. The article presents the results of the study which investigated the efficacy of the comprehensive treatment of osteoarthritis of knee joints in patients using the combined exposure to naphthalan applications with irradiation using the non-selective Bioptron chromotherapy in the sanatorium. 64 patients aged 40-69 years with stage 1-3 knee osteoarthritis were examined and treated. It was shown that the combined use of naphthalan and non-selective chromotherapy in patients with gonarthrosis reduces pain, improves the functional state of the affected knee joints and improves the quality of life of patients in the absence of adverse effects. A comparative analysis of the study results showed that the efficacy of the combined use of naphthalan and non-selective chromotherapy is superior to the isolated effect of naphthalan.

Application of red light phototherapy in the treatment of radioactive dermatitis in patients with head and neck cancer.

BACKGROUND: To observe the effect of red light phototherapy (RLPT) on radioactive dermatitis (RD) caused by radiotherapy in patients with head and neck cancer (HNC). METHODS: Sixty patients with HNC admitted to our hospital were randomly divided into experimental group and control group, 30 patients in each group. The control group received routine daily care during radiotherapy treatment. In the experimental group, in addition to routine daily care during radiotherapy treatment, photon therapy apparatus RLPT was added, 10 min/time, 2 times/day, and lasted until the end of radiotherapy. The pain and conditions of the patients' skin were assessed daily, and the skin pain and dermatitis grades of the two groups were compared. RESULTS: In terms of the reaction degree of RD, experimental group was mainly grade 0-2, and control group was mainly grade 2-3, with a significant difference (P < 0.05). In terms of skin pain, according to the pain records at week 2, 3, and 4, the pain degree increased with time. However, the score of wound pain in experimental group was significantly lower than that in control group, and there was a significant difference between the two groups (P < 0.05). CONCLUSIONS: The application of RLPT in the treatment of RD can help accelerate wound healing and significantly shorten healing time. It can not only reduce wounds pain of patients, promote inflammation and ulcer healing, but also ensure the smooth progress of patients' radiotherapy and improve their quality of lives, which is worth popularization and application in the clinical practice.

Effect of phototherapy with turquoise vs. blue LED light of equal irradiance in jaundiced neonates.

BACKGROUND: Blue light with peak emission around 460 nm is the preferred treatment of neonatal hyperbilirubinemia. However, studies using fluorescent light tubes have suggested that turquoise light with peak emission at 490 nm may be more efficient. At present, the predominant light source for phototherapy is light emitting diodes (LEDs). Hence, the aim of this study was to compare the bilirubin-reducing effect in jaundiced neonates treated either with turquoise or with blue LED light with peak emission at 497 or 459 nm, respectively, with equal irradiance on the infants. METHODS: Infants with gestational age ≥33 wk and uncomplicated hyperbilirubinemia were randomized to either turquoise or blue LED light and were treated for 24 h. The mean irradiance footprint at skin level was 5.2 × 10(15) and 5.1 × 10(15) photons/cm(2)/s, respectively. RESULTS: Forty-six infants received turquoise light and 45 received blue light. The median (95% confidence interval) decrease of total serum bilirubin was 35.3% (32.5; 37.3) and 33.1% (27.1; 36.8) for infants treated with turquoise and blue lights, respectively. The difference was nonsignificant (P = 0.53). The decrease was positively correlated to postnatal age and negatively to birth weight. CONCLUSION: Using LED light of equal irradiance, turquoise and blue lights had equal bilirubin-reducing effect on hyperbilirubinemia of neonates.

Preparative separation and purification of fumigaclavine C from fermented mycelia of Aspergillus fumigatus CY018 by macroporous adsorption resin.

In this work, the separation and purification of fumigaclavine C (FC), an ergot alkaloid with strong anti-inflammatory activity from fermented mycelia of Aspergillus fumigatus was systematically evaluated. Among the eight tested resins, the non-polar resin D101 displayed the best adsorption and desorption based on of static adsorption and desorption tests. Adsorption isotherms were constructed on D101 resin and fitted well to the Freundlich model. Dynamic adsorption and desorption tests on a column packed with D101 resin have been investigated for optimization of chromatographic parameters. Under optimized conditions, the contents of FC increased from 7.32% (w/w) in the crude extract to 67.54% in the final product with a recovery yield of 90.35% (w/w) via one run. Furthermore, a lab scale-up separation was carried out, in which the FC content and recovery yield were 65.83% and 90.13%, respectively. These results demonstrated that this adsorption-desorption strategy by using D101 resin was simple and efficient, thus showing potential for large scale purification and preparation of FC in the future.

New advances in countercurrent chromatography and centrifugal partition chromatography: focus on coupling strategy.

Countercurrent chromatography (CCC) is an attractive separation method because the analytes are partitioned between two immiscible liquid phases avoiding problems related to solid stationary phase. In recent years, this technique has made great progress in separation power and detection potential. This review describes coupling strategies involving high speed CCC (HSCCC) or centrifugal partition chromatography (CPC). It includes on-line extraction-isolation, hyphenation with mass spectrometry (MS) and nuclear magnetic resonance (NMR) detectors, multidimensional CCC (MDCCC), two-dimensional CCC (2D-CCC), on-line coupling with liquid chromatography (LC), and biological tests, and innovative off-line developments. The basic principles of each method are presented and applications are summarized.

[Mental and autonomic disorders in children and adolescents with diabetes mellitus type I and their correction using color and rhythm therapy].

The objective of the study was to work out a method of color and rhythm therapy (CRT) for correction of mental and autonomic disorders in children with diabetes mellitus type I. The elaboration of the method was based on the results of examination of 62 patients, aged 7-16 years. In addition, a psychometric assessment of anxiety (the Spielberger-Khanin test), stress resistance and communicative abilities (the Luscher color test), depression (the scale of Saint-Petersburg Bekhterev's Psychoneurological Research Institute) and autonomic dysfunctions (the Vein's questionnaire) was performed. CRT was conducted with the apparatus"Color-rhythm" that allows to perform stimulation with the light of specified length. The high effectiveness of CRT in the correction of mental and autonomic disorders depending on the character of disorders and effects of separate photic stimuli (red or yellow, green and blue), sequence and rhythm of their presentation is demonstrated. The choice of automatic working regime of the apparatus is proved to be optimal.

Comparison of the efficacy of conventional special blue light phototherapy and fiberoptic phototherapy in the management of neonatal hyperbilirubinaemia.

The efficacy and usefulness of two types of phototherapy differing in the source, wavelength and irradiance of the light, conventional phototherapy consisting of special blue light and fiberoptic phototherapy, were compared in a relatively larger series of term newborns with non-haemolytic and more significant hyperbilirubinaemia than those in previous studies. In total, 108 newborns were allocated sequentially to receive either conventional phototherapy consisting of five special blue lamps or fiberoptic phototherapy. The average spectral irradiance measured at the skin surface level of newborns during the study period was significantly greater in the conventional phototherapy group. The special blue lamp of the conventional phototherapy unit had an emission spectrum almost identical to the bilirubin absorption spectrum, whereas the tungsten-halogen lamp of the fiberoptic phototherapy had a broad emission through the blue and green wavelengths (mainly in the green spectrum). Phototherapy was more effective in the conventional phototherapy group; the duration of exposure to phototherapy (h) was significantly shorter, and the overall bilirubin decline rate (as micromol/l/h and %/h) was significantly greater in the conventional phototherapy group. According to the nursing personnel, fiberoptic phototherapy was more comfortable than the conventional phototherapy frame because of the easier accessibility and handling of the infants during phototherapy. They complained of giddiness, nausea, glare, temporary blurring of vision and difficulty in detecting the skin colour changes of newborns with the blue light of the conventional phototherapy unit. Conventional phototherapy consisting of special blue fluorescent lamps with approximately twofold higher irradiance and an emission spectrum almost identical to the bilirubin absorption spectrum is preferable to fiberoptic phototherapy in the standard treatment of term newborns with non-haemolytic hyperbilirubinaemia.
