Aim: Recent data have suggested that effective control of postprandial blood glucose can reduce the risk of macroangiopathic complications of diabetes, especially cardiovascular risk. 1,5-Anhydro-D-glucitol (1,5-AG) has been proposed as a marker of short-term hyperglycaemic excursions. We aimed to evaluate its usefulness in patients with type 2 diabetes and have attempted to indicate when 1,5-AG monitoring should be used in ordinary diabetes care settings. Methods: The study group consisted of 130 type 2 diabetic patients aged 3669 years. 1,5-AG plasma level, HbA1c concentrations and daily glucose profile were measured. Mean blood glucose (MBG), M-value were calculated and maximal daily glycaemia (MxG) was established as indicators of short-term hyperglycaemic episodes. Results: 1,5-AG plasma level was negatively and HbA1c was positively correlated with fasting glycaemia (FG), MBG, M-value and MxG. Multivariate regression analysis revealed that 1,5-AG plasma level is determined by MxG only, while FG determined HbA1c concentration in blood. The analysis of 1,5-AG level and HbA1c distributions in well and poorly controlled patients revealed that persons with low HbA1c values may have decreased 1,5-AG plasma level. Conclusion: 1,5-AG plasma level monitoring is the useful method to identify well controlled, exclusively based on HbA1c levels type 2 diabetic patients with transient hyperglycaemia, accordingly patients at high risk of macroangiopathic complications.

Background/Aims: Recent experimental research revealed that statins at low doses induce angiogenesis, which in turn may be related to the course of atherosclerosis. There are no clinical studies evaluating the effect of ‘low-dose' statins on serum levels of angiogenesis regulators in diabetic subjects. We aimed to explain how low doses of statins modify the serum concentrations of two potent proangiogenic factors, vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF), in patients with type 2 diabetes. Methods: Measurements of fasting glucose level, HbA1c, 1,5-anhydro-D-glucitol and lipid profile were taken from 47 patients with type 2 diabetes treated with low doses of atorvastatin (10 mg daily) or simvastatin (10-20 mg daily), from 45 statin-free patients with type 2 diabetes and from 23 nondiabetic subjects. Measurements of VEGF and bFGF in serum were taken using the BD™ Cytometric Bead Array. Results and Conclusion: Statins used in low doses in patients with type 2 diabetes reduce the serum concentration of VEGF and bFGF which suggests antiangiogenic potential of these doses. Nevertheless, this effect could be neutralized by postprandial hyperglycemia.

Eryngium creticum Lam. (E. cyaneum Sibth. & Sm., E. syriacum Lam.), Saniculoideae, Apiaceae is of great importance in the traditional Greco – Arab medicine. This study was carried out in order to contribute to the ethnopharmacological knowledge of this medicinal species. This review describes the botanical characterization and distribution, as well as critically assesses the phytochemical properties and biological activities of E. creticum, a species that has been used in traditional medicine for many decades. Possible trends and perspectives for future research of this plant are discussed, as well. E. creticum has been found to contain several chemical constituents, mostly sesquiterpenes, monoterpenes, aldehydes, coumarins, sitosterols and sugars. Eryngo with its bioactive compounds possesses a wild range of biological activities. It was reported that in traditional medicine E. creticum was applied mainly as the remedy for snake and scorpion bites. Some published studies have shown a broad spectrum of biological and pharmacological activities, including anti-snake and anti-scorpion venom, as well as antibacterial, antifungal and antileishmanial effects. Other have indicated antihyperglycemic, hypoglycemic and antioxidant activities of this species. The in vitro studies and in vivo models have provided a simple bioscientific explanation for its various ethnopharmacological uses
