[Humoral regulation of nutritional status in children].

The purpose of the research was the investigation of the characteristics of insulin resistance, levels of adipokines, myokines and collagen metabolites type I in children in orphanages and social rehabilitation centers (SRC). The study involved 69 children aged 7-12 years. The first group consisted of 20 children from SRC, the second - 16 children living in orphanages, control group included 33 children (1-2 health groups) from wealthy families. The average length of stay of children in SRP was 1.0 (0.5-2.5) month, in orphanages - 38 (22-44) months. The groups were comparable in age and sex. Anthropometric indices were determined, in blood serum glucose concentration was measured by glucose oxidase method, blood serum level of insulin, cortisol, leptin, adiponectin, resistin, apelin, myostatin, collagen metabolites were determined by ELISA. Children from orphanages and SRC had significantly lower anthropometric indices in comparison with the control group. Particularly low parameters were observed in children from SRP, which in growth, body weight, chest circumference and body mass index significantly lagged behind the control group peers. The children from SRP as compared with the control group revealed higher insulin resistance index (3.33±0.49 vs 2.29±0.29, p<0.05) and cortisol level (405.21±38.21 vs 313.08±25.97 nmol/l, p>0.05). There were changes (p<0.05) in blood serum content of adipokines - reduced leptin level (5.35±1.55 vs 14.00±3.10 ng/ml) and increased apelin level (4.07±0.82 vs 2.19±0.41 ng/ml), as well as higher levels (p<0.05) of myostatin (183.95±16.3 vs 116.4±9.4 ng/ml) and C-terminal telopeptide of type I collagen (1.11±0.11 vs 0.72±0.08 ng/ml). The children in orphanages compared with the control group had lower levels of insulin (5.04±0.69 vs 11.3±1.12 µIU/ml), high insulin sensitivity - HOMA-IR was 1.01±0.16. The children in orphanages have even more pronounced reduction in leptin concentration (2.69±0.4 ng/ml), a decrease of resistin (4.99±0.32 vs 7.16±0.70 ng/ml, p<0.05), increased concentration (p<0.05) of apelin (3.53±0.67 ng/ml), myostatin (181.17±10.2 ng/ml) and C-terminal telopeptide of type I collagen (2.70±0.22 ng/ml). Features of hormone and cytokine regulation of metabolism make it particularly urgent to prevent disorders of eating behavior and to promote a healthy lifestyle among children left without parental care.

[Assessment of morphological changes in oral mucosa in patients with gastrointestinal pathology].

Anatomical and functional proximity of oral and digestive tract organs as well as common mechanism of innervation and humoral regulation create prerequisites for the involvement of oral cavity in pathological processes developing in the gastrointestinal tract. Various gastric and duodenal substances affect oral tissues during frequent refluxes and produce lesions in epithelium of oral mucosa. Results of preliminary qualitative assessment of morphological changes in lingual mucosa are presented for patients with acid-dependent pathology.

[The efficacy of the polyphenol plant preparation piflamin in drug damage to the liver]. / Effektivnost' rastitel'nogo preparata piflamina pri lekarstvennom porazhenii pecheni.

The hepatoprotective properties of the flavonoid preparation piflamine of field-peas grass were studied on a model of experimental paracetamol liver damage. Piflamine was found to normalize the parameters of carbohydrate, protein, and lipid metabolism, increase the activity of the antioxidant system, and restore the processes of bile production and bile secretion. The drug is prospective due to its quite cheap and available source of raw materials.
