Animal venomous secretions have been explored as source of active substances affecting mammal hemostasis. These active principles impinge on key elements of almost all physiologic pathways and have an enormous potential in the development of new therapeutic drugs. The envenomation caused by the caterpillar Lonomia obliqua (lonomism) is characterized by a hemorrhagic clinical profile. Investigations...
Snake bites caused by viperid snakes of Atheris genus are extremely rare, envenoming of a bite of related viper Proatheris superciliaris was described only once in the literature. The present case study depicts the envenoming of a 57 years old Czech man, a private herpetologist, who was bitten to his finger. He developed painful local reaction, nausea, hematuria, hypertension, chest and lumbar pain...
Snake venom metalloproteinases (SVMPs) play a prominent role in the local and systemic manifestations of viperid snakebite envenomations. Thus, the possibility of using metalloproteinase inhibitors in the treatment of these envenomations is a promising therapeutic alternative. This study assessed the ability of two metalloproteinase inhibitors, the biphosphonate clodronate and the tetracycline doxycycline,...
Many snake venoms contain procoagulant toxins that activate the coagulation cascade and cause venom-induced consumptive coagulopathy (VICC). We developed a semi-mechanistic model of the clotting cascade in order to explore the effects of the procoagulant toxin from taipan venom on this system as well as the effects of antivenom. Simulations of the time course in the change of clotting factors were...
