Echinochrom, a new antioxidant of the polyhydroxynaphthaquinone class, was tested for its cardioprotective activity in a model of occlusive reperfusion myocardial infarction (90-min occlusion and 4-hour reperfusion) in the acute experiments with open-chest dogs. The bolus intravenous injection of echinochrom in a dose of 1 mg/kg 5 min before reperfusion(More)
Changes in the diameter of brain vessels and intensity of collateral blood flow typical of chronic ischemia were detected by magnetic resonance imaging in senescence-accelerated OXYS rats demonstrating reduced (compared to Wistar rats) research and exploratory activity. Histochrome (antioxidant drug) produced positive effects on cerebral vessels in OXYS(More)
Echinochrome A (Ech A) is a natural pigment from sea urchins that has been reported to have antioxidant properties and a cardio protective effect against ischemia reperfusion injury. In this study, we ascertained whether Ech A enhances the mitochondrial biogenesis and oxidative phosphorylation in rat cardio myoblast H9c2 cells. To study the effects of Ech A(More)
Echinochrome A (Ech A) is a naphthoquinoid pigment from sea urchins that possesses antioxidant, antimicrobial, anti-inflammatory and chelating abilities. Although Ech A is the active substance in the ophthalmic and cardiac drug Histochrome®, its underlying cardioprotective mechanisms are not well understood. In this study, we investigated the protective(More)
The efficacy of a new bioantioxidant histochrome is studied in 92 patients (98 eyes). The drug was injected subconjunctivally or parabulbarly in a dose of 0.5 ml 0.02% solution daily, 7-10 injections per course. The clinical effect of histochrome is determined by the localization, duration, and extent of the process. The drug was the most effective in the(More)
Echinochrome A (EchA) is a dark-red pigment of the polyhydroxynaphthoquinone class isolated from sea urchin Scaphechinus mirabilis. Acetylcholinesterase (AChE) inhibitors are used in the treatment of various neuromuscular disorders, and are considered as strong therapeutic agents for the treatment of Alzheimer's disease (AD). Although EchA is clinically(More)
Echinochrome A (Echi A) improves mitochondrial function in the heart; however, its effects on skeletal muscle are still unclear. We hypothesized that Echi A administration during short-term exercise may improve exercise capacity. Twenty-four male Sprague-Dawley rats were randomly divided into the following groups: control group (CG), Echi A-treated group(More)
The effect of the antioxidant histochrom on the size of the myocardial infarction and activity of the cardioselective enzyme creatine phosphokinase was studied in 45 patients with acute myocardial infarction during thrombolytic therapy. Changes in blood plasma histochrom concentration were studied in 7 patients with myocardial infarction after a single(More)
Lipid peroxidation and blood rheology were assessed in the course of treatment with antioxidant histochrome and placebo of 66 unstable angina pectoris (UAP) patients. Histochrome has a high antioxidant activity and effectively inhibits accumulation of lipoperoxides in plasma and red cells of UAP patients, promotes stabilization of blood cell function and(More)
Hepatoprotective properties of ethanol extract from the roots of Maackia amurensis Ruper et Maxim have been studied on the model of toxic hepatitis induced by carbon tetrachloride damage. It is established that the extract contains daidzein, 7-O-gentobiosides of isoflavonoids genistein, formononetin, pseudobabtige-nin, and 5-O-methylgenistein, and(More)
