hydroxycoumarin/hemorrhage

Coumarin forms in melilotoside (trans-ortho-coumaric acid glucoside)-containing plant species upon cell damage. In moldy melilotoside-containing plant material, trans-ortho-coumaric acid is converted by fungi to 4-hydroxycoumarin, two molecules of which spontaneously combine with formaldehyde to

The toxic dose of rodenticides in children is extremely difficult to be determined because of the uncertain exposure history. We established and validated a method to identify the toxic dose in children of 4-hydroxycoumarin (TDCH). Items were selected by Delphi method and weighted by analytic

A 32-year-old patient died of a cerebellar haemorrhage and the blood coagulation analysis before death suggested defective synthesis of vitamin K-dependent clotting factors due to vitamin K deficiency. The post-mortem toxicological examination of different tissues revealed phenprocoumon poisoning as

Oral anticoagulants of the 4-hydroxycoumarin class, typified by warfarin, are used worldwide to treat thromboembolic disease. These drugs show the beneficial attributes of high efficacy and low cost, but patient management can be complicated by their narrow therapeutic index and wide

7-Hydroxycoumarin (HC) or Umbelliferone exerts many beneficial effects, ie. antioxidant, anti-tumour, anti-inflammatory and immunomodulatory activities. We hypothesized that HC had mitigating properties on ulcerative colitis (UC) induced by dextran sulfate sodium (DSS) in mice, via suppression of

The acute LD50s of ferulenol were determined in albino mice by single po or ip as 2,100 and 319 mg/kg bw, respectively. Ferulenol had a higher LD50 compared to warfarin and thus has a lower acute toxicity. Three days after ferulenol administration, dosed animals showed hypoprothrombinemia with

Warfarin and other 4-hydroxycoumarins are effective antithrombotic agents. They affect four blood coagulation proteins that act sequentially to produce thrombin. Coumarin therapy decreases the biological activity of these proteins, and therefore decreases the rate at which blood clots. As the

A large-scale outbreak of life-threatening, inhaled synthetic cannabinoids (Spice/K2)-associated coagulopathy with bleeding complications was recently reported in Illinois. The causative agents were brodifacoum, difenacoum, and bromadiolone, potent, long-acting, 4-hydroxycoumarin anticoagulant

Ferula communis is an ombelliferous plant of the Mediterranean regions. It is represented in Morocco by two varieties: brevifolia and genuina. The later is very rich in a soap or resinous gum. This product, collected from the roots, is largely used in traditional medicine. It is know as fessoukh in

The increased prevalence of rodents resistant to warfarin led to the development of the hydroxycoumarin anticoagulant brodifacoum. A 25-year-old man attempted suicide by consuming four boxes of d-CON Mouse-Prufe II; each box contains 42 g of bait that is 0.005% brodifacoum. He presented to a

The 4-hydroxycoumarin derivatives are the most used rodenticides and act as classical anticoagulants, interfering with the production of clotting factors in liver by antagonizing the action of vitamin K reductase, thereby inhibiting recycling of vitamin K1, involved in activation of blood clotting
