Snake venom possesses various kinds of proteins and neurotoxic polypeptides, which can negatively interfere with the neurotransmitter signaling cascade. This phenomenon occurs mainly due to the blocking of ion channels in the body system. Envenomation prevents or severely interrupts nerve impulses from being transmitted, inhibition of adenosine triphosphate synthesis, and proper functioning of ...

PURPOSE To investigate the effects of hydroalcoholic leaf extract of Mikania glomerata Spreng (Asteraceae) on the activity of Bothrops jararaca snake venom in Wistar rats. METHODS Fifty four rats Wistar were divided into six groups of nine animals in each: control treated with saline; control treated with B. jararaca venom; control treated with M. glomerata extract; B. jararaca venom incubate...

Most snake venom toxins are proteins, and participate to envenomation through a diverse array of bioactivities, such as bleeding, inflammation, and pain, cytotoxic, cardiotoxic or neurotoxic effects. The venom of a single snake species contains hundreds of toxins, and the venoms of the 725 species of venomous snakes represent a large pool of potentially bioactive proteins. Despite considerable ...

OBJECTIVE To describe the clinical features and laboratory findings in patients with definite red-bellied black snake (RBBS; Pseudechis porphyriacus) bites, including correlation with results of venom assays. DESIGN, PATIENTS AND SETTING Prospective cohort study of patients with definite RBBS bites, recruited to the Australian Snakebite Project from January 2002 to June 2010. MAIN OUTCOME M...

neutralization effects of acorus calamus and withania somnifera root extracts were tested against echis carinatus venom. both plant extracts were effectively neutralized the various pharmacological activities induced by echis carinatus venom. about 0.14 mg of acorus calamus and 0.16 mg of withania somnifera root extracts were able to completely neutralize the lethal activity of 2ld 50 of echis ...

Snake venoms are complex mixtures of biologically active proteins and peptides. Many affect haemostasis by activating or inhibiting coagulant factors or platelets, or by disrupting endothelium. Snake venom components are classified into various families, such as serine proteases, metalloproteinases, C-type lectin-like proteins, disintegrins and phospholipases. Snake venom C-type lectin-like pro...

OBJECTIVE With the help of bioinformatics analysis, we wished to develop a novel antivenom against the Deinagkistrodon (D.) acutus snake venom using B-cell linear epitopes of three primary toxins (serine protease, metalloprotease, and phospholipase A2). MATERIALS AND METHODS cDNA sequences of three toxins of D. acutus venom were retrieved from the NCBI database. B-cell linear epitopes were pr...

Annually 2.5 million people are bitten by snakes, more than 100,000 fatally. In India a large no of people suffer and die every year due to snake venom poisoning. Venom has been used in the treatment of a variety of pathophysiological conditions in Ayurveda, homeopathy and folk medicine. Snake venom is a natural biological resource, containing a complex mixture of enzymes, peptides and protein ...

Snake venoms are complex toxin mixtures. Viperidae and Crotalidae venoms, which are hemotoxic, are responsible for most of the envenomations around the world. Administration of antivenins aimed at the neutralization of toxins in humans is prone to potential risks. Neutralization of snake venom toxins has been achieved through different approaches: plant extracts have been utilized in etnomedici...

Snake venoms have been subjected to increasingly sensitive analyses for well over 100 years, but most research has been restricted to front-fanged snakes, which actually represent a relatively small proportion of extant species of advanced snakes. Because rear-fanged snakes are a diverse and distinct radiation of the advanced snakes, understanding venom composition among "colubrids" is critical...
