The nature of addiction depends on various factors. The tendency to have already used several addictive substances and to seek high sensation experiences as a result of specific personality traits may lead to extreme and peculiar forms of addictions. Even belonging to specific social and cultural background may lead to such forms of addiction such as intentional snake bite and willful envenomation. In this article, we have discussed the peculiarities and practical insight of such addiction to snake venom. The possible molecular mechanism behind such venom-mediated reinforcement has also been highlighted...

In various human diseases, an increase in capillary permeability to proteins leads to the loss of protein-rich fluid from the intravascular to the interstitial space. Although sepsis is the disease most commonly associated with this phenomenon, many other diseases can lead to a "sepsis-like" syndrome with manifestations of diffuse pitting edema, exudative serous cavity effusions, noncardiogenic pulmonary edema, hypotension, and, in some cases, hypovolemic shock with multiple-organ failure. The term capillary leak syndrome has been used to describe this constellation of disease manifestations associated with an increased capillary permeability to proteins...

Snake venom phospholipases A2 (PLA2) share high sequence identities and a conserved structural scaffold, but show important functional differences. Only a few PLA2s have been purified and characterized from coral snake (Micrurus spp.) venoms, and their role in envenomation remains largely unknown. In this report, we describe the isolation, sequencing and partial functional characterization of two Micrurus PLA2s: MmipPLA2 from Micrurus mipartitus and MdumPLA2 from Micrurus dumerilii, two species of clinical importance in Colombia...

Bothrops atrox snakes are the leading cause of snake bites in Northern Brazil. The venom of this snake is not included in the antigen pool used to obtain the Bothrops antivenom. There are discrepancies in reports on the effectiveness of this antivenom to treat victims bitten by B. atrox snakes. However, these studies were performed using a pre-incubation of the venom with the antivenom and, thus, did not simulate a true case of envenomation treatment. In addition, the local lesions induced by Bothrops venoms are not well resolved by antivenom therapy...

Dilated nonreacting pupils are routinely taken as a sign of irreversible brain damage. Alpha-receptor stimulation (scorpion sting) and presynaptic acetylcholine receptor blocker (krait bite) may result in dilation of pupils without involvement of the brain. This study was aimed to clinically evaluate the response of pupils in scorpion sting and krait bite. Victims of scorpion sting and krait bite were chosen from Raigad district. Scorpion sting and krait bite cases were admitted to hospital and were clinically evaluated in detail regarding neurological manifestations...

In Colombia, Bothrops asper is responsible for 70-90% of ophidians accidents reported annually. Envenoming occurs mainly in rural areas where both antivenom and health centers are scarce. Thus, patients are frequently treated by local healers that employ medicinal herbs; including several species belonging to Dracontium genus. In this work, we evaluated the neutralizing activity of Dracontium dubium Kunth against the lethal, inflammatory, coagulant and hemolytic effects produced by B. asper venom. Mice treated with D...

Females of the ectoparasitoid Habrobracon hebetor attack and envenomate numerous host individuals during oviposition. The vectoring of the entomopathogenic fungus Beauveria bassiana during the adhesion stage by ectoparasitoid females among the wax moth larvae Galleria mellonella was explored under laboratory conditions. Vectoring occurred both from infected parasitoids to wax moth larvae and from infected to healthy wax moth larvae by parasitoids. The efficacy of vectoring in both cases was dose dependent. Parasitoid females were unable to recognize infected larvae in a labyrinth test...

Cnidarian envenomations are the leading cause of severe and lethal human sting injuries from marine life. The total amount of venom discharged into sting-site tissues, sometimes referred to as "venom load", has been previously shown to correlate with tentacle contact length and sequelae severity. Since <1% of cnidae discharge upon initial tentacle contact, effective and safe removal of adherent tentacles is of paramount importance in the management of life-threatening cubozoan stings. We evaluated whether common rinse solutions or scraping increased venom load as measured in a direct functional assay of venom activity (hemolysis)...

Animal venom research is a specialized investigation field, in which a number of different methods are used and this array is constantly expanding. Thus, recently emerged omics and nanotechnologies have already been successfully applied to venom research. Animal venoms have been studied for quite a long time. The traditional reductionist approach has been to isolate individual toxins and then study their structure and function. Unfortunately, the characterization of the venom as a whole system and its multiple effects on an entire organism were not possible until recent times...

α2-macroglobulins are broad-spectrum endopeptidase inhibitors, which have to date been characterised from metazoans (vertebrates and invertebrates) and Gram-negative bacteria. Their structural and biochemical properties reveal two related modes of action: the "Venus flytrap" and the "snap-trap" mechanisms. In both cases, peptidases trigger a massive conformational rearrangement of α2-macroglobulin after cutting in a highly flexible bait region, which results in their entrapment. In some homologs, a second action takes place that involves a highly reactive β-cysteinyl-γ-glutamyl thioester bond, which covalently binds cleaving peptidases and thus contributes to the further stabilization of the enzyme:inhibitor complex...

There are multiple reports of recreational snake envenomation describing psychotropic effects in absence of any adverse effects. This is in contradiction with known effects of snake venom. We report a case of a young male who subjected himself to repeated envenomation by a snake purported to be 'Indian Cobra' and experienced a 'high'. However, a direct identification of snake revealed it was a benign 'Rat snake'. We attempt to explain the reported psychological effects as a result of high expectation of rewarding experience, strong suggestion, personality traits and most importantly the dangerous nature of willfully receiving snakebites...

Amputation of a limb is a serious consequence of snakebite poisoning. It is caused by the toxicity of the venom and often the use of a tourniquet in some patients, which can lead to limb ischemia. Management of the victim aims to ensure survival and preserve the function of the bitten limb. Antivenom immunotherapy is the only specific treatment for ophidian envenomation. It is indicated in cases of general symptoms and signs related to the bite, but also if local damage could lead to the loss of limb function...

North American rattlesnake envenomations are known to produce coagulopathies and thrombocytopenia. However, the occurrence of delayed hematologic toxicity (less than seven days after envenomation) is poorly characterized in the medical literature. While the recurrence of hematologic derangements has been documented following envenomation, it is usually in the absence of clinically significant bleeding. Although commonly recommended to treat delayed coagulopathies, the effectiveness of crotalidae polyvalent immune Fab ovine (CroFab®) in managing this condition remains in question and warrants further investigation and exploration...

Envenomation by Loxosceles spider can result in two clinical manifestations: cutaneous and systemic loxoscelism, the latter of which includes renal failure. Although incidence of renal failure is low, it is the main cause of death, occurring mainly in children. The sphingomyelinase D (SMase D) is the main component in Loxosceles spider venom responsible for local and systemic manifestations. This study aimed to investigate the toxicity of L. intermedia venom and SMase D on kidney cells, using both In vitro and in vivo models, and the possible involvement of endogenous metalloproteinases (MMP)...

Although several studies have shown that scorpion venoms cause a systemic inflammatory response syndrome, little is known about the contribution of the hematopoietic organs. The aim of this study was to investigate the effect of Androctonus australis hector venom on the bone marrow and on local inflammatory mediators, in concordance with the systemic inflammatory reaction elicited in mice. The consequences of a direct interaction of venom with murine bone marrow cells were also assessed by in vitro study. Obtained results showed that the early systemic neutrophilia correlated with a rapid granulocyte mobilization...
