Summary:

The purpose of this work is to study the relationship of carbohydrate metabolism disorders and markers of endo-thelial dysfunction in animals with absolute insulin defciency at biostimulation by autotransplantation of the skin fap. Material and Methods. The study was conducted on 60 male white outbred rats, which were divided into: an intact control group, a two comparative and an experimental group. In animals of the comparison group, alloxan diabetes mellitus (DM) was caused, in rats from the experimental group, an autotransplantation of the skin fap was performed against the background of developed alloxan diabetes. The levels of glycated hemoglobin (HbA1c), glucose, C-reactive protein (CRP) and vascular endothelial growth factor (VEGF) were determined. Results. Autotransplantation of the skin fap causes a normalization of the glycemic profle in animals of the experimental group, and also reduces subclinical infammation caused by hyperglycemia and stabilizes the expression of VEGF.Diabetes causes an increase in HbA1c by 69 % and CRP by 11 %, while аutotransplantation of the skin fap leads to a decrease in the concentration of HbA1c by 28 % and CRP by 7 %. Conclusion. Autotransplantation of the skin fap reduces the risk of microcirculatory disorders due to hyperglycemia and chronic subclinical infammation.

Sexual dimorphism of dynamics of concentration of endothelium alteration factors in blood in surgical treatment of chronic generalized periodontitis.

Summary:

Aim: to study the sexual dimorphism of the concentration in the blood of endothelial alteration factors in the dynamics of the surgical treatment of moderate chronic generalized periodontitis (CGP) in comparison with clinically healthy volunteers. Material and Methods. A total of 20 clinically healthy volunteers (average age is 30 (24; 37), 50% are men) and 31 patients with moderate chronic generalized periodontitis (average age is 31 (27; 38), 40% are men) were examined. Serum concentrations of homocysteine and C-reactive protein were determined. Patients with chronic generalized periodontitis were treated following the surgical scheme. Results. In patients with chronic generalized periodontitis, prior to treatment, an increased level of homocysteine and C-reactive protein (CRP) was detected in the serum. Conservative treatment in the preoperative period caused a decrease in the level of homocysteine in patients, while there was no significant change in the rate of C-reactive protein. 10 days after the surgery, an increase in the concentration of homocysteine and C-reactive protein in serum was observed in patients of both sexes, indicating a reactive change. At the same time, reactive changes were more pronounced in women. Long-term results of surgical treatment of chronic generalized periodontitis indicate a decrease in C-reactive protein and homocysteine levels in patients of both sexes. Sexual dimorphism was manifested by the fact that women had lower homocysteine content than men: 9.4 (8.9; 9.7) versus 13.3 (10.8; 14.1) umol/l (p=0,004). Conclusion. Patients of both sexes with moderate chronic generalized periodontitis have elevated C-reactive protein and homocysteine levels. Sexual dimorphism is manifested by higher levels of homocysteine, but not C- reactive protein in men. The acute period of surgical treatment of chronic generalized periodontitis is characterized by an increase in the concentration of factors affecting the endothelium in the blood, which are more pronounced in women. Long-term surgical treatment results of chronic generalized periodontitis demonstrate a decrease of homocysteine and C-reactive protein levels in blood with homocysteine levels being lower in women than in men.

Summary:

Purpose: To establish diagnostic value of the increased content of pro- and anti-inflammatory cytokines (IL-8, MCP-1, RAIL) in gingival fluid at patients with a chronic periodontal disease. Material and Methods: 60 patients with inflammatory periodontal diseases were surveyed. The concentration of the studied cytokines in gingival fluid has been defined. Results: At a periodontal disease the increased level of pro- and anti-inflammatory cytokines in gingival fluid has been noted. Conclusion: Definition of the MCP-1 and IL-8 levels in gingival fluid can be used as a criterion of the prognosis of the severity of inflammatory and destructive processes in the periodontal tissues.
