14. Preliminary assessment of Hedychium coronarium essential oil on fibrinogenolytic and coagulant activity induced by Bothrops and Lachesis snake venoms
Background The search for new inhibitors of snake venom toxins is essential to complement or even replace traditional antivenom therapy, especially in relation to compounds that neutralize the local effects of envenomations. Besides their possible use as alternative to traditional antivenom therapy, some plant species possess bioactive secondary metabolites

15. Inhibitory effect of a Brazilian marine brown alga Spatoglossum schröederi on biological activities of Lachesis muta snake venom
The ability of crude extracts of the brown seaweed Spatoglossum schröederi to counteract some of the biological activities of Lachesis muta snake venom was evaluated. In vitro assays showed that only the extract of S. schröederi prepared in ethyl acetate was able to inhibit the clotting of fibrinogen induced by L. muta venom. On the other hand, all extract

16. Serpentes peçonhentas e ofidismo em Cruzeiro do Sul, Alto Juruá, Estado do Acre, Brasil
Apesar da importância dos acidentes ofídicos na Saúde Pública, são relativamente poucas as pesquisas realizadas sobre esse tema no Brasil. Devido aos poucos estudos sobre ofidismo na Amazônia e especialmente no estado do Acre, trabalhos epidemiológicos são de grande relevância. Esse estudo apresenta a lista de serpentes peçonhentas e aspectos epide

17. Development of a sensitive enzyme immunoassay (ELISA) for specific identification of Lachesis acrochorda venom
The snake genus Lachesis provokes 2 to 3% of snakebites in Colombia every year. Two Lachesis species, L. acrochorda and L. muta, share habitats with snakes from another genus, namely Bothrops asper and B. atrox. Lachesis venom causes systemic and local effects such as swelling, hemorrhaging, myonecrosis, hemostatic disorders and nephrotoxic symptoms similar

18. Caracterização bioquímica, estrutural e funcional de uma L-aminoácido oxidase isolada de peçonha de Lachesis muta (Serpentes, Viperidae) / Purification, biochemistry and functional characterization of a new L-amino acid oxidase from Lachesis muta venom.
As peçonhas de serpentes contêm uma mistura complexa de substâncias farmacologicamente ativas, como metaloproteases, fosfolipases A2, serino-proteases, L-aminoácido oxidase (LAAO), além de outros importantes compostos sem ação enzimática. LAAOs são flavoproteínas que catalisam a desaminação oxidativa de L-aminoácidos e produzem o -cetoácido cor

19. Anti-snake venom effect of secodolastane diterpenes isolated from Brazilian marine brown alga Canistrocarpus cervicornis against Lachesis muta venom
The effect of a Brazilian algae extract and also a mixture of two secodolastane diterpenes (linearol/isolinearol) that were isolated from the marine brown alga Canistrocarpus cervicornis were evaluated against biological activities of Lachesis muta snake venom. In vitro assays showed that the crude extract and the diterpenes were able to inhibit the clotting

20. Estudo dos efeitos renais do veneno da serpente Lachesis muta muta. / Study of renal effects of Lachesis muta muta venom.
The accident caused by the snake Lachesis muta muta is serious and its venom is responsible for many systemic changes, such as hypotension. In this work, the renal effects of the total venom of this snake in the renal perfusion system and in cultured renal tubular cells of the type MDCK (Madin-Darby Canine Kidney) are investigated. Isolated kidneys from Wist

21. Antiophidian properties of plant extracts against Lachesis muta venom
Snakebites comprise a serious health problem in several countries due to their global incidence, which exceeds 2.5 million per year, and the elevated number of victim fatalities. To counteract envenomations, antivenoms have been used regularly for more than a century. Apart from side effects including anaphylactic reactions, antivenoms are not able to effici

22. Aspectos ecológicos e epidemiológicos de acidentes ofídicos em comunidades ribeirinhas do baixo rio Purus, Amazonas, Brasil
Acidentes ofídicos foram registrados em dez comunidades ribeirinhas do baixo rio Purus através de entrevista às vítimas. Os ribeirinhos responderam perguntas sobre a percepção ambiental da ecologia das serpentes envolvidas nos acidentes. O tamanho das serpentes e a altura da mordida no corpo foram estimados com fita métrica. A correspondência entre o

23. Purification and biochemical and functional characterization of fibrinogen from plasma of Bothrops jararaca (Wied, 1824) (Ophidia: Viperidae, Crotalinae) / Purificação e caracterização bioquímica e funcional do fibrinogênio do plasma da serpente Bothrops jararaca (Wied, 1824) (Ophidia: Viperidae, Crotalinae)
Fibrinogen is a plasma glycoprotein that is composed of two sets of three nonidentical polypeptide chains (Aα Bβ and ϒ ) which are covalently linked by disulfide bonds. Thrombin cleaves fibrinogen to form fibrin and, consequently, the fibrin clot. This work describes the purification and characterization of fibrinogen from Bothrops jararaca (B

24. Caracterização dos efeitos inflamatorios induzidos pelo veneno bruto e pela LmTX-I de Lachesis muta muta (Surucucu) em ratos / Characterization of inflamatory effects induced by Lachesis muta muta (Surucucu) and LmTX-I in rats
The ability of crude venom and a basic phospholipase A2 (LmTX-I) from Lachesis muta muta venom to increase the microvascular permeability in the rat paw and skin has been investigated. Crude venom or LmTX-I were injected subplantarly or intradermically, after which oedema was measured at selected times thereafter. Paw volume was measured using a hydropletism
