BACKGROUND: Troxerutin (TRX) has a beneficial effect on blood viscosity and platelet aggregation, and is currently used for the treatment of chronic varicosity. Recently, TRX can improve lipid abnormalities, glucose intolerance and oxidative stress in high-fat diet-induced metabolic disorders. In this study, we tested the effect of TRX on metabolic syndrome-associated disorders using a non-obese model of metabolic syndrome-the Hereditary Hypertriglyceridaemic rats (HHTg). METHODS: Adult male HHTg rats were fed standard diet without or with TRX (150 mg/kg bwt/day for 4 weeks). RESULTS: Compared to untreated rats, TRX supplementation in HHTg rats decreased serum glucose (p<0.05) and insulin (p<0.05). Although blood lipids were not affected, TRX decreased hepatic cholesterol concentrations (p<0.01) and reduced gene expression of HMGCR, SREBP2 and SCD1 (p<0.01), involved in cholesterol synthesis and lipid homeostasis. TRX-treated rats exhibited decreased lipoperoxidation and increased activity of antioxidant enzymes SOD and GPx (p<0.05) in the liver. In addition, TRX supplementation increased insulin sensitivity in muscles and epididymal adipose tissue (p<0.05). Elevated serum adiponectin (p<0.05) and decreased muscle triglyceride (p<0.05) helped improve insulin sensitivity. Among the beneficial effects of TRX were changes to cytochrome P450 family enzymes. Hepatic gene expression of CYP4A1, CYP4A3 and CYP5A1 (p<0.01) decreased, while there was a marked elevation in gene expression of CYP1A1 (p<0.01). CONCLUSION: Our results indicate that TRX improves hepatic lipid metabolism and insulin sensitivity in peripheral tissues. As well as ameliorating oxidative stress, TRX can reduce ectopic lipid deposition, affect genes involved in lipid metabolism, and influence the activity of CYP family enzymes.

The objective of the study was to estimate the association of pregnant women with varicose veins of lower extremities (VVLE) and the possible risk for adverse birth outcomes and among them different congenital abnormalities (CAs) in their children. Prospectively and medically recorded VVLE were evaluated in 332 pregnant women who delivered infants with CA (case group) and 566 pregnant women with VVLE who delivered infants without CA (control group) and matched to cases were compared in the population-based data set of the Hungarian Case-Control Surveillance System of Congenital Abnormalities, 1980-1996. About one-quarter of pregnant women had chronic VVLE while new onset VVLE occurred in the rest of pregnant women. There was no higher risk for adverse birth outcomes of pregnant women with VVLE, in fact the rate of preterm birth and low birth weight was somewhat lower than in the newborns of pregnant women without VVLE. The comparison of VVLE occurrence in pregnant women who had offspring with 21 different CA groups and in pregnant women who later delivered babies without CA showed a higher risk only for pectus excavatum, a mild CA. In conclusion, VVLE in pregnant women does not associate with obvious hazard for their fetuses.

The effect of 7-mono-hydroxyethylrutoside and its combination with acetylsalicylic acid was evaluated in a controlled clinical trial, performed in 105 patients with obliterative atherosclerosis of the lower limbs, and using non-invasive measurement of peripheral haemodynamic parameters--blood flow during reactive hyperaemia and ankle systolic blood pressure. Patients, randomized into three groups, received either placebo or 7-mono-hydroxyethylrutoside alone or in combination with acetylsalicylic acid for 12 months. The placebo group showed a decrease in maximum calf blood flow and a decrease in ankle systolic pressure. Administration of 7-mono-hydroxyethylrutoside did not lead to any significant changes in systolic pressure but there was a decrease in the maximum calf blood flow. There were no statistically significant changes in patients receiving the 7-mono-hydroxyethylrutoside and acetylsalicylic acid combination who, by contrast, showed a tendency to increased values of the parameters measured.

The endothelo-protective activity of a series of low-molecular oxygen-derived free radical scavengers (OFRS) was tested in rats. A model of endothelaemia provoked by intravenous administration of hydrogen peroxide was used. With each OFRS the activity in the hydrogen peroxide model was compared with that in the less specific model using the provocation by citrate as a calcium chelating agent. Relatively unspecific but biologically important OFRS, ascorbic acid, tocopherol, troxerutin and glutathione were tested in the first phase of the study. A marked optimum of endothelo-protective activity was shown with all agents, the optimum against hydrogen peroxide having been observed at doses from 3 to 50 times lower than against citrate. Ascorbic acid, troxerutin and the combination of both were also tested in another model based on leg ischaemia produced by ligature of the common femoral artery. Without OFRS, a marked increase of endothelaemia was observed after 30-60 min ischaemia showing a second peak after the release of the ligature. This second peak was completely abolished by the preventive administration of OFRS in a dose which was also effective in the hydrogen peroxide model.

Clinical and experimental evidence support the metabolic aetiology of diabetic microangiopathy. This paves the way for its management by transplantation of endocrine pancreas. In an informative article, the authors attempts to conceptualize their position concerning indications for pancreas transplantation and offer a review of their own experimental studies, a prerequisite before actual clinical application.
