In normal persons and in diabetics with and without tissue injuries was tried to find out a connection between the glycolyzed haemoglobin and the parameters of hypoxia. In a small number of cases no clearly evident correlation between the concentrations of the 2,3-diphosphoglycerate and the lactate
In the pathogenesis of III-IV stage diabetic angiopathy, the important place belongs to oxygen deficiency and metabolic acidosis. Introduction into the complex of treatment of the patients of hyperbaric oxygenation and endolymphatic pharmacotherapy contributes to improvement of general state of the
Diabetes is associated with a fluctuating impairment in oxygen transport of the erythrocytes. This impairment is correlated with hyperglycemia by the formation of glycosylated hemoglobin (HbAIC) and with inhibitory factors of glycolysis i.e. hypophosphatemia and acidosis which lower the
The metabolic disorders, hormonal, genetic, immunological, reological factors, plasmorrhagia, hypoxia result in the simultaneous or subsequent damage to small vessels and thus are involved in the development of the diabetic microangiopathy. The degree of microangiopathy depends on the duration and
Risk factors of tissue hypoxia was investigated in 26 patients with diabetic retinopathy (DMR), who compared with 62 patients without DMR. significant higher incidence of DMR was found in patients with poor diabetic control (HbA 1 greater than or equal to 10%), with orthostatic hypotension (OH),
Proceeding from biochemical and instrumental investigations on a vast material (560 patients with various forms of diabetes mellitus) and literature data the authors propose a new concept of occurrence and progression of diabetic microangiopathies. Importance is attached to tissue hypoxia related to
Multiple factors, including altered levels of vasoactive substances, altered vasomotor responsiveness, chronic plasma volume expansion, and tissue hypoxia, contribute to a state of generalized microvascular vasodilatation in early insulin-dependent diabetes mellitus. This vasodilatation, with the
One of the most severe complications of atherosclerosis is arterial occlusive disease (AOD) and with diabetic angiopathy (DA), is a common chronic problem in clinical practice worldwide. Hyperbaric oxygen (HBO) therapy is a therapeutic modality for solving all forms of Granulocyte-colony stimulating factor (G-CSF) has been shown to play a neuroprotective role in ischemic stroke by mobilizing bone marrow (BM)-derived endothelial progenitor cells (EPCs), promoting angiogenesis, and inhibiting apoptosis. Impairments in mobilization and function of the BM-derived EPCs
Reversible abnormalities of many vascular beds have been observed in early diabetes, before irreversible structural changes of diabetic microangiopathy became apparent. In the bulbar conjenctiva and in the kidney the changes are associated with vascular dysfunction and may be due to autonomic
BACKGROUND
Vascular endothelial growth factor (VEGF) plays an important role in diabetic vascular complications, and its expression is affected directly or indirectly by hypoxia inducible factor-1α (HIF-1α) and insulin-like growth factor-I (IGF-I) in tumors and certain normal cell lines. However,
OBJECTIVE
Pericytes play a specialized role in regulating angiogenesis and vascular function by providing vascular stability and controlling endothelial cell proliferation. Disorders in pericyte function and pericyte-endothelial interaction have been observed in several disease states including
The receptor tyrosine kinase Axl is involved in diabetic vascular disease. This study aims to investigate the effect of high glucose on endothelial cells injury and Axl expression in hypoxia condition in vitro, and we present details of the mechanism associated with overexpression of Axl rescue the
Microvascular complications of diabetes include retinopathy, nephropathy and neuropathy. The first signs of these complications may develop in children and adolescents, particularly if insulin treatment has been inadequate. The mechanisms by which diabetic microangiopathy develop are not known, but
Evidence for a causative relationship between prolonged tissue hypoxia and diabetic retinopathy and glomerulosclerosis are presented. Based on the assumption that one of the most fundamental requirements for optimal cellular metabolism is a constant cellular oxygen tension, the "three-in-one
