aims: venomous snake bites are public health problems in different parts of the world. the most specific mainstay in the treatment of envenomation is anti-venom. to treat the envenomation, it is very important to identify the offending species. this study was designed to determine the penetrating pattern of fangs and teeth of some viper snakes.  materials & methods: this descriptive study was p...

background: snakebite is a serious public health problem in the world. the annual incidence of snakebites ranges from 4.5-9.1 in 100,000 population in iran. with regard to diversity of envenomation profiles in different geographical parts of iran, the aim of this study was to determine the demographical data, clinical and laboratory findings, and the outcome of the snakebite victims referred to...

Cases of snakebite envenomation are frequently presented to veterinary practitioners in southern Africa. Despite this, no published guidelines exist on how this medical emergency should be managed. Southern African snake venoms can be classified into 3 main types based on the main mechanism of venom action and clinical presentation. A polyvalent antivenom is manufactured in South Africa and con...

Snake bite is crucial medical emergency while the success of immediate care and anti-venom therapy mainly depend on the correct identification of culprit snake. We present a simple method for identification of six snake species including Echiscoloratus, Echispyramidum, Cerastescerastesgaspreti, Bitisarieatans, Najahaje Arabica, andWalterinnesiaaegyptia, using the gel filtration chromatographic ...

The effects of various viperid and elapid venoms on the cellular biology of tumour-associated microvascular endothelial cells (TAMECs) were determined in the current study using cells isolated from a rat mammary adenocarcinoma. Previous studies to determine the effects of snake venoms on endothelial cells in vitro have in the main been performed on either human umbilical vein endothelial cells ...

1. Tiger snake antivenom, raised against Notechis scutatus venom, is indicated not only for the treatment of envenomation by this snake, but also that of the copperhead (Austrelaps superbus) and Stephen's banded snake (Hoplocephalus stephensi). The present study compared the neuromuscular pharmacology of venom from these snakes and the in vitro efficacy of tiger snake antivenom. 2. In chick biv...

Crotalus durissus cumanensis, a rattlesnake endemic to Colombia and Venezuela, is considered one of the most lethal snake species in Latin America. The aim of the present study was to compare the protein content and biological activity of the venom obtained from eight specimens of C. durissus cumanensis, namely two adults from different localities of Colombia and six offspring born in captivity...

The observation that snake venoms are able to hydrolyze thymus and yeast nucleic acids was first made by Delezenne and Morel (1) in 1919. This discovery remained practically forgotten until 1945 when Gulland and Walsh (2) employed the nuclease in the venom of Vipera russelli in studying the composition of yeast ribonucleic acid. The presence of nucleases in snake venoms assumes a r61e of great ...
