1. Como operacionalizar o atendimento de pacientes indígenas vítimas de acidentes ofídicos nas comunidades indígenas remotas da Amazônia Brasileira?
Os antivenenos são o único tratamento eficaz contra os efeitos de picadas de cobras venenosas e sua aplicação imediata é crucial para evitar complicações, sequelas e morte
. Desse modo, enquanto não ocorre a descentralização do tratamento antiveneno para unidades básicas de saúde indígena mais próximos das populacionais indígenas, os

2. Synthesis and Biological Evaluation of Novel 1,3-Benzoxathiol-2-one Sulfonamides against Toxic Activities of the Venom of Bothrops jararaca and Bothrops jararacussu Snakes
This work describes the synthesis of new 1,3-benzoxathiol-2-one sulfonamides and evaluation of their ability to inhibit some in vitro (coagulant, proteolytic and hemolytic) and in vivo (hemorrhagic, edematogenic and lethality) toxic activities of Bothrops jararaca and Bothrops jararacussu venoms. Compounds have been synthesized from the coupling of intermedi

3. The deadliest snake according to ethnobiological perception of the population of the Alto Juruá region, western Brazilian Amazonia
Abstract INTRODUCTION: We examined the ethnobiological perception of the population of the Alto Juruá region about different snake species, in terms of their dangerousness and manifestations of envenomation. METHODS: We interviewed 100 villagers who were active in the forests. RESULTS: Lachesis muta was considered the most venomous snake, and Bothrops at

4. Local and systemic effects caused by Crotalus durissus terrificus, Crotalus durissus collilineatus, and Crotalus durissus cascavella snake venoms in swiss mice
Abstract INTRODUCTION: Crotalus envenomations cause serious complications and can be fatal without appropriate treatment. Venom isoforms present and inter/intraspecific variations in the venom composition can result in different symptoms presented by bites by snakes from the same species but from different geographical regions. We comparatively evaluated th

6. Envenomation by an opisthoglyphous snake, Erythrolamprus aesculapii (Dipsadidae), in southeastern Brazil
Abstract Snakebites by aglyphous or opisthoglyphous snakes are common in Brazil. We report a case of snakebite by the opisthoglyphous Erythrolamprus aesculapii. The victim presented with pain, edema, and bleeding at the bite site, along with erythema, similar to a Bothrops envenomation. In this type of snakebite, if the snake is not brought to the hospital,

7. Effects of copaiba oil on dermonecrosis induced by Loxosceles intermedia venom
ABSTRACT Background: Accidents caused by spiders of the genus Loxosceles constitute an important public health problem in Brazil. The venom of Loxosceles sp induces dermonecrosis at the bite site and systemic disease in severe cases. Traditional medicine based on plant-derived products has been proven to reduce the local effects of envenomation. The present

9. A case of envenomation caused by Oxybelis fulgidus (Serpentes, Colubridae) in Brazilian Amazon
Abstract A case of a bite inflicted by Oxybelis fulgidus in the wilds of Amazon is reported. The patient was a 67-year-old man who presented with dizziness, tachycardia and local pain, with erythema and bleeding in his left arm. The venom of Oxybelis fulgidus, a neotropical rear-fanged snake, contains one of the four three-finger toxins already isolated from

10. Clinical and laboratory features distinguishing between Deinagkistrodon acutus and Daboia siamensis envenomation
Abstract Background: There are 6 species of venomous snakes in Taiwan. Two of them, Deinagkistrodon acutus (D. acutus) and Daboia siamensis (D. siamensis), can cause significant coagulopathy. However, a significant proportion of patients with snakebites cannot identify the correct snake species after envenomation, which hampers the application of antivenom.

11. Kn-Ba: a novel serine protease isolated from Bitis arietans snake venom with fibrinogenolytic and kinin-releasing activities
Abstract Background: Bitis arietans is a venomous snake found in sub-Saharan Africa and in parts of Morocco and Saudi Arabia. The envenomation is characterized by local and systemic reactions including pain, blistering, edema and tissue damage, besides hemostatic and cardiovascular disturbances, which can cause death or permanent disabilities in its victims

12. Sequence analysis of the cDNA encoding for SpCTx: a lethal factor from scorpionfish venom ( Scorpaena plumieri )
Abstract Background: Lethal factors are multifunctional oligomeric proteins found in the venomous apparatus of Scorpaeniformes fish. These toxins elicit not only an array of biological responses in vitro but also cardiovascular disorders and strong hemolytic, nociceptive and edematogenic activities in vivo. This work describes the cloning and molecular iden
