REVIEW
Karl Egil Malterud
The ethnopharmacology, chemistry and pharmacology of four Malian medicinal plants, Biophytum umbraculum, Burkea africana, Lannea velutina and Terminalia macroptera are reviewed. These plants are used by traditional healers against numerous ailments: malaria, gastrointestinal diseases, wounds, sexually transmitted diseases, insect bites and snake bites, etc. The scientific evidence for these uses is, however, limited. From the chemical and pharmacological evidence presented here, it seems possible that the use in traditional medicine of these plants may have a rational basis, although more clinical studies are needed...

Snake bite is an important health hazard in tropics. Snake envenomation in pregnancy may cause fetal death and maternal mortality or morbidity. However, little is known about the toxic effects and optimal management during pregnancy after snake envenomation because of the rarity of cases. Herein, we report a case of a pregnant woman who was successfully treated for snake bite-induced acute kidney injury during the third trimester. She was treated with equine-derived polyvalent anti-snake venom without development of any adverse effects, hemodialysis, and supportive therapy...

INTRODUCTION: Snake bites have cardiotoxicity, neurotoxic, myotoxic, nephrotoxic, and hemotoxic features. The neutrophil/lymphocyte ratio (NLR) provides valuable information for the determination of the diagnosis and prognosis of various diseases. In this study, we aimed to investigate the relationship between NLR with the development of complications and duration of hospital stay in snakebite cases. METHOD: In this study, 107 patients with snakebite complaints that applied to a tertiary care university hospital between 2011 and 2014 were retrospectively reviewed...

We describe 70 cases of monocled cobra (Naja kaouthia) bite admitted to Chittagong Medical College Hospital, Bangladesh. The biting snakes were identified by examining the dead snake and/or detecting N. kaouthia venom antigens in patients' serum. Bites were most common in the early morning and evening during the monsoon (May-July). Ligatures were routinely applied to the bitten limb before admission. Thirty-seven patients consulted traditional healers, most of whom made incisions around the bite site. Fifty-eight patients experienced severe neurotoxicity and most suffered swelling and pain of the bitten limb...

The Ceylon krait (Bungarus ceylonicus) is a deadly venomous elapid snake endemic to Sri Lanka. Its habitat is mainly in the wet zone of the island. Despite its frequent encounters in and near human dwellings, reports of envenoming are rare and limited to four in the literature. The first and last fatal reports envenoming by B. ceylonicus was in 1993. After over two decades, we report two confirmed cases of B. ceylonicus bites-one a dry bite and the other with signs and symptoms of moderate envenoming. The envenoming occurred at night while the victim was asleep, causing tightness in the chest and dyspnoea on waking up, followed by neuromuscular paralysis that did not cause respiratory failure and complete recovery was observed three days following the bite...

Russell's viper bites are potentially fatal from severe bleeding, renal failure and capillary leakage. Snake venom metalloproteinases (SVMPs) are attributed to these effects. In addition to specific antivenom therapy, endogenous inhibitors from snakes are of interest in studies of new treatment modalities for neutralization of the effect of toxins. Two major snake venom metalloproteinases (SVMPs): RVV-X and Daborhagin were purified from Myanmar Russell's viper venom using a new purification strategy. Using the Next Generation Sequencing (NGS) approach to explore the Myanmar RV venom gland transcriptome, mRNAs of novel tripeptide SVMP inhibitors (SVMPIs) were discovered...

Antivenoms against bites and stings from snakes, spiders, and scorpions are associated with immunological side effects and high cost of production, since these therapies are still derived from the serum of hyper-immunized production animals. Biotechnological innovations within envenoming therapies are thus warranted, and phage display technology may be a promising avenue for bringing antivenoms into the modern era of biologics. Although phage display technology represents a robust and high-throughput approach for the discovery of antibody-based antitoxins, several pitfalls may present themselves when animal toxins are used as targets for phage display selection...

BACKGROUND: Snakebites are not a reportable condition (to state health departments), and 1 major assessment of US children with snakebites was published 50 years ago. Increasing urbanization, population shifts south and west, newer antivenom therapy, and the importation of exotic snakes may have changed snakebites. Poison control centers are often consulted on treatment and collect surveillance data. METHODS: Generic codes for venomous, nonvenomous, and unknown snakebites were used to characterize victims aged ≤18 years reported to US poison control centers between 2000 and 2013...

The proteome composition of western India (WI) Russell's viper venom (RVV) was correlated with pharmacological properties and pathological manifestations of RV envenomation. Proteins in the 5-19 and 100-110 kDa mass ranges were the most predominate (∼35.1%) and least abundant (∼3.4%) components, respectively, of WI RVV. Non-reduced SDS-PAGE indicated the occurrence of multiple subunits, non-covalent oligomers, self-aggregation, and/or interactions among the RVV proteins. A total of 55 proteins belonging to 13 distinct snake venom families were unambiguously identified by ESI-LC-MS/MS analysis...

REVIEW
Vivek Chauhan, Suman Thakur
Snake bite envenomations are common in rural areas and the incidence peaks during monsoons in India. Prominent venomous species have been traditionally labeled as the 'big four' that includes Cobra, Krait, Russel's viper and Saw scaled viper. Systematic attempts for identification and classification of prevalent snakes in various states of India are missing till now and there is no concrete data on this aspect. The published literature however shows that some species of snakes are more prevalent in a particular region than the other parts of India e...
