Pharmacological treatment is not always effective and, in some cases, is accompanied by side effects. However, some factors associated with osteoarthritis, such as muscle dysfunction and decreased physical activity, may be improved through physical rehabilitation. In this article, we describe the pathogenesis, clinical manifestations and approaches to physical rehabilitation for biomechanical disorders associated with primary osteoarthritis of the knee (gonarthrosis).
Two different concepts for developing direct HPLC-UV methods for quantifying fosfomycin trometamol were developed without any derivatization and modification of the analyte. In the first concept, without the use of alkylamines as ion-pairs in the mobile phase, by using cyanopropyl CN and a strong anion-exchanger column, we investigated the possibility of their highly polar and anion-exchanging forces and mechanisms to retain, separate and detect trometamol without the help of additional agents or modifiers. In the second concept, the most frequent reversed-phase C18 columns with different characteristics and vendors were tested in combination with different length-based alkylamines with 3–10 C atoms in their chains. In our research, we found that the ion-pairing of fosfomycin with 6–10 C-atom-based alkyl-length of aliphatic chains manifested the most appropriate strength of interactions between alkyl-paired trometamol molecules and octadecylsilane or C18 bonded RP column to achieve optimal retention, selectivity and peak shape on chromatograms, with the possibility for the fine-tuning of elution time. The simplicity of our method concept omits the need for expensive and sophisticated columns like HILIC, C30 graphite carbon, and mixed-mode-based columns for easier retaining, separation, and determination of fosfomycin, and for its quantification purposes, especially in high-throughput analyses in regular quality-control laboratories.
Background. Drinking mineral water is one of the ethnopharmacologic factors. Organic substances, despite their presence in all drinking mineral waters, are still considered to be active only in the water of Naftussya type (which, due to mineralization less than 1 g/L, are not formally mineral), whereas the physiological activity of true mineral waters (which mineralization is greater than 1-2 g/L) are associated with electrolytes and trace elements. Previously, we identified the role of organic carbon and nitrogen of mineral waters in their effects on certain metabolic and neuro-endocrine parameters. The purpose of this study is to clarify the role of organic substances of same mineral waters in their effects on immunity parameters. Material and methods. Experiment was performed on 48 healthy female Wistar rats 240-290 g divided into 5 groups. Animals of the first group for 6 days administered a single tap water through the tube at a dose of 1,5 mL/100 g of body mass. In the second group we administered the water Naftussya from the Truskavets’ layer (Galychyna, Ukraine), in the third group the water Sophiya of the Truskavets’ field. The rats of the fourth group received the native water from the Hertsa (Bucovyna, Ukraine) field, and the last group received its artificial salt analogue. The day after the completion of the drinking course in all rats immunne parameters were registered. Results. On the basis of the correlation analysis with step-by-step exclusion, 9 immune parameters (Endotheliocytes of Thymus, Spleen Mass Index, Entropy of Splenocytogram, Natural Killers, B- and 0-Lymphocytes, Rod-shaped Neutrophils, Phagocytic Index and Microbian Count of Monocytes of Blood) are included in the regressive model for organic nitrogen (R=0,818) and 6 parameters (Endotheliocytes of Thymus, Fibroblastes and Reticulocytes of Spleen, Pan-Lymphocytes, Microbian Count of Neutrophils and Phagocytic Index of Monocytes of Blood) for organic carbon (R=0,690). Together, the organic components of the chemical composition of loading fluids determine their effect on the immune parameters by 77%. Conclusion. Organic substances of mineral waters play an essential role in their effects on the immune parameters of female rats.
The aim of this research was the comparative study of the content of the amino acids in the herb and tubers of Stachys sieboldii. The study of the amino acid composition of the raw materials was carried out using high-performance liquid chromatography (HPLC). The results obtained have shown that the aerial parts of plants investigated have higher amino acid content than the underground organs. Free and bound L-aspartic acid, L-proline, and L-phenylalanine were present in the analyzed samples in the greatest amount. Moreover, L-cysteine was found only in Stachys sieboldii tubers in amounts (8.11 mg/g). This research established that Stachys sieboldii herb and tubers have the most suitable amino acids composition and are prospective for further pharmacological studies.
