rutin and Thrombosis

The role of a mixture of phlebotonics in the treatment of acute hemorrhoid crisis is investigated to test their efficacy.. One hundred and thirty-four consecutive patients with an acute hemorrhoidal crisis recruited in five colorectal units entered the study. Sixty-six of them were randomized to receive a mixture of diosmin, troxerutin and hesperidin (group A), and 68 a placebo (group B). The main symptoms, the use of oral painkillers and the Bristol scale score were recorded at each scheduled visit and compared using both Student's t test for independent samples and the ANOVA models for repeated measures. The presence of edema, prolapse and thrombosis were also recorded and compared using the Chi-square test. Furthermore, the trend of proportions during the time of the evaluations was assessed by the Chi-square test for linear trend.. Pain, bleeding and the proportion of patients who reported persistence of edema and thrombosis decreased significantly after 12 days of treatment in group A. After 6 days, the number of paracetamol tablets taken by patients in group A was significantly lower than the amount of flavonoid mixture.. The use of a mixture of diosmin, troxerutin and hesperidin is a safe and effective mean of managing symptoms of acute hemorrhoidal disease. Furthermore, in patients receiving treatment, there was faster control and lower persistence of edema and thrombosis.

A multi-centre, double blind randomized clinical trial was designed to assess the efficacy and safety of orally administered 0-(beta-hydroxyethyl)-rutosides (HR) capsules in the treatment of 101 patients with post-thrombotic syndrome. Seventeen patients were excluded from the analysis for violation of the study protocol, 41 received HR capsules (1,200 mg/day) and 43 placebo. Mean follow-up scores at the 4th and 8th week show that the HR patients displayed an improved state of tiredness as compared to the placebo's. The mean circumference of the calf for the HR group decreased from 390 (+/- 33) mm at visit one to 382 (+/- 33) mm at visit three, with a mean circumference reduction of 8.7 (+/- 8) mm, compared to a steady placebo circumference of 387 (+/- 31) mm at all 3 visits with a mean circumference reduction of only 2 mm (+/- 9). The estimated treatment effect at week 8 was -6.7 mm, 95% confidence interval (-10.3, -3.0). The mean circumference of the ankle, decreased from 243 (+/- 20) mm to 238 (+/- 20) mm at the 4th week, contrasted with a constant placebo circumference of 241 (+/- 22) mm at both visits. The estimated treatment effect at week 4 was -5.4 mm, 95% confidence interval (-10.2, -0.6). However, at week 8, the estimated treatment effect was only -3.4 mm, 95% confidence interval (-8.6, +1.8). In conclusion, HR capsules may show an improvement in the clinical symptoms and may show a mean circumference reduction of the calf and ankle at the 8th week, in patients with post-thrombotic syndrome.

Analysis of thrombohemorrhagic complications was conducted in 98 patients, operated on for various forms of chemoresistant pulmonary tuberculosis. To prevent such complications it is necessary to prescribe heparin in minimal doses or fraxiparine preoperatively and intraoperatively. It permits to lower the prethrombotic background significantly, to prevent thrombohemorrhagic complications, and in their incidence--to eliminate thrombotic and hemorrhagic clinical features with minimal losses.

This study was purposed to explore the effect of troxerotin and cerebroproptein hydrolysate injection (TCHI) on platelet aggregation in vitro and thrombosis in vivo. The inhibitory rate of TCHI at different concentrations on platelet aggregation was determined by platelet aggregometer. The relationship between dose and effect was established. The effect of troxerutin and cerebroproptein hydrolysate injection on thrombosis was determined by the carotid thrombosis model of rats. The results showed that the TCHI could inhibit thrombosis and platelet aggregation in a concentration-dependent way. When the concentration of TCHI total nitrogen was 5 µg/ml, the inhibition rate of platelet aggregation reached to the highest value of 28.61 ± 22.07%, which is 2.5 times as much as that with 100 µg/ml aspirin. It is concluded that the TCHI has antiaggregative and antithrombotic activity effects against platelet aggregation and thrombosis.

Rat tail thrombosis (RTT) induced by i.v. injection of kappa-carrageenin was not inhibited by p.o. or i.p. administration of the aglucon of rutin, quercetin, but it was slightly inhibited by rutoside-containing Venoruton. The RTT was significantly inhibited by didymlaevulinate, Helodym 88, whereas samarium-containing Phlogosol gave inconsistent results because of the solvent propylene glycol. The RTT model is suitable to detect substances of the flavonoid and lanthanide types with weak antithrombotic activity.

Two highly sensitive models of arterial and venous thrombosis forming with the test of endothelial stability a complementary system with a maximum stress on the role of vascular lesion were used to test a series of four antithrombotic drugs (heparin, acetylsalicylic acid, dipyridamole, sulfinpyrazone) and four drugs with other indications but with an antithrombotic activity in experiment (prenylamine, troxerutin, ketanserin and pizotifen). All drugs, except heparin, were given orally. Whereas heparin, aspirin and prenylamine had mixed effects on both arterial thrombosis (i.e. mostly on platelet functions) as well as on endothelial stability, ketanserin and pizotifen had a predominant effect on the former while dipyridamole, troxerutin and sulfinpyrazone influenced mostly the latter function.

A series of drugs representing several groups of antithrombotics was tested in a new model of arterial thrombosis in rats. Thrombosis was produced in the aorta by the combination of local partial obstruction and systemic administration of hypotonic saline with serotonin. High efficacy was demonstrated with heparin, acetylsalicylic acid, troxerutin, prenylamine, antiserotonin agents /pizotifen, ketanserin/ and particularly with the combinations of antiserotonins and the above mentioned antithrombotic drugs. The model showed high sensitivity to all tested drugs in the clinical dose range.
