Properties of cell wall polysaccharides of raw nectarine fruits after treatment under conditions that modulate gastric digestion.

The results of the study of the physicochemical properties of the high-molecular-weight soluble and insoluble components of nectarine cell walls obtained by fruit treatment under conditions that modulate of gastric digestion are presented. Homogenized nectarine fruits were sequentially treated by natural saliva and simulated gastric fluid (SGF) at pH 1.8 and 3.0. The isolated polysaccharides were compared with polysaccharides obtained by sequential extraction of nectarine fruit with cold, hot, and acidified water, solutions of ammonium oxalate and sodium carbonate. As a result, high-molecular-weight water-soluble pectic polysaccharides, weakly bound in the cell wall, were dissolved in the simulated gastric fluid, regardless of pH. Homogalacturonan (HG) and rhamnogalacturonan-I (RG-I) were identified in all pectins. It was shown that their quantity and ability to form highly viscous solutions determine high values of the rheological characteristics of the nectarine mixture formed under simulated gastric conditions. The modifications occurring with the insoluble components under the influence of acidity of SGF were importance. They determined difference in the physicochemical properties of both the insoluble fibres and the nectarine mixtures.

[Role of health resort factors in the treatment of delayed puberty in teenage girls]. / Rol' sanatorno-kurortnykh faktorov v lechenii zaderzhki polovogo razvitiia u devochek-podrostkov.

Both treatment and effective rehabilitation play an important role in preserving the reproductive health of the girl, the future mother. Along with the search for new drug therapies for various gynecological pathologies, it is important to use physical and natural factors that are natural stimuli for the patient's body. AIM: To examine the effect of health resort factors and methods of physiotherapy on the general condition and hormonal status of girls with delayed sexual development. MATERIAL AND METHODS: 83 patients with delayed sexual development who were examined at the children's clinical sanatorium 'Zdravnitsa' in Yevpatoria (Crimea) were examined: 52 girls were included in the primary group, 31 - in the comparison group. Both groups, depending on age, were divided into subgroups: 13-14 years old and 15-17 years old. Patients in both groups received a standard treatment complex (STC). In addition to SCR, the girls of the main group were prescribed: 5% brine electrophoresis by sinusoidal modulated currents, sage and sea baths. The control group included gynecologic ally healthy adolescents: thirteen 13-14 year-old girls old in the subgroup K1 and twelve 15-17 year-old girls in the subgroup K2. Before and after treatment, all patients underwent standard clinical, gynecological, and laboratory examinations. In both groups, the dynamics of clinical and laboratory parameters, as well as gonadotropic and sex steroid hormones in the blood serum were analyzed. RESULTS: The complex of climatic and physical factors had a nonspecific general stimulating effect. There was a positive dynamics in the general condition of patients, their anthropometric indicators, hormonal status, which was more pronounced in the primary group than in the comparison group. Negative dynamics of the course of diseases in girls of both groups was not observed. CONCLUSION: The use of hardware physiotherapy and sage baths increases the effectiveness of STC. The best clinical and laboratory dynamics of the primary indices was noted in patients 13-14 years old than in patients 15-17 years old. The use of natural and preformed physical factors in treatment makes it possible to minimize the drug effect on the body and achieve the most positive treatment results with a minimum of side effects.
