Proliferative Potential of Adipose Tissue in Type 2 Diabetes Mellitus and Superinvasive Opisthorchiasis

INTRODUCTION: The article presents the results of studying the proliferative activity of adipocytes and of neoangiogenesis in adipose tissue in healthy individuals, in those who died with type 2 diabetes mellitus and with superinvasive opisthorchiasis. The parasite is the original factor that triggers productive processes due to the mutation of numerous proliferative genes. Stem cells are initiated with their subsequent differentiation along the lines of various differons. AIM: to identify proliferative processes and processes of neoangiogenesis of adipose tissue in type 2 diabetes mellitus and superinvasive opisthorchiasis. MATERIALS AND METHODS: sectional material (n = 58): group 1 — healthy individuals (n = 10), group 2 — deceased with type 2 diabetes mellitus from accidental causes (n = 22), group 3 — persons with superinvasive opisthorchiasis died by violence, with duration of invasion more than 10 years (n = 26). The material was subjected to routine histological examination, including histochemical and immunohistochemical staining methods. Further, microscopy was carried out with subsequent statistical analysis. RESULTS: reduction of the proliferative activity of adipose tissue cells in type 2 diabetes mellitus and increase in the parameters in opisthorchiasis invasion compared with healthy individuals were revealed; in diabetes mellitus, the hypertrophic variant of adipose tissue prevailed, the volumetric density of blood vessels decreased, while in patients with superinvasive opisthorchiasis, lipolysis and angiogenesis increased. CONCLUSION: predictors of type 2 diabetes mellitus were assumed to be low proliferative activity of adipocytes, low volumetric density of blood vessels and hypertrophic variant of adipose tissue. With high mitotic activity and hyperplastic variant of adipose tissue, like in superinvasive opisthorchiasis, a protective effect is formed, which can be considered in the context of a predictor factor of type 2 diabetes mellitus.
