ABSTRACT. 100 Topchiyeva Shafiga and Babaev Elmar: Thermoprotective Properties of the Venom of the Transcaucasian Vipera (Macrovipera Lebetina Obtusa Dyigubsky, 1832) Table 1. 2.1. It was established that at heating up to the temperature of 1200C, crystals of Macrovipera Lebetina Obtusa venom have maximum resistance, and after cooling its property restores. ANTI-VENOM. Macrovipera lebetina is the most prominent species from this genus, with an extensive geographic range from the Middle East extending throughout central Asia [64,65]. Macrovipera lebetina obtusa (Dwigubsky, 1832) and Montivipera xanthina (Gray, 1849) (Ottoman Viper) are viper snakes from Viperidae family and found in various locations in Anatolia. It cleaves the Arg(1545)-Ser(1546) linkage in the human factor V molecule. In this study, we investigated the antiâangiogenic activity of lebectin, a newly discovered CLP from Macrovipera lebetina venom. Despite the viper's large size, data on its body mass and sex-specific morphological differences are scarce. For instance, Phospholipases type A2 (PLA2s) from the Tunisian vipers Cerastes cerastes and Macrovipera lebetina has been found to have anti-tumor activity. The blunt-nosed viper (Macrovipera lebetina) is a snake whose venom is one of the deadliest in the world. In this study, we extend this observation to lebecetin, a second C-type lectin isolated from the same venom and previously reported as a potent inhibitor â¦ We investigated the balance of free radicals in different tissues (liver, heart, brain and muscle) of rats in course of in vivo and in vitro processing by Macrovipera lebetina obtusa (MLO) and Montivipera raddei (MR) snake venoms. Viperidae is one family of venomous snakes that is found nearly worldwide. Chemiluminescence (ChL) levels were examined in tissue assays after incubation (at 37 °C for a period of 10 min) with venom for in vitro experiments and â¦ The LD as well as HD concentration of the crude venom were obtained to be 45 Î¼g and 120 Î¼g/ml, respectively. We recently reported that lebectin, a novel C-type lectin from Macrovipera lebetina venom, displays an anti-integrin activity. Venom and antivenoms Venom from Macrovipera lebetina obtusa (Mlo) was pooled from 10 adult individuals between 80 and 110 cm in length and older than 3 years, of both sexes, collected, during the day in spring and autumn and in summer nights, in different regions of the Republic of Dagestan (Russian Federation). Lebein, is an heterodimeric disintegrin isolated from Macrovipera lebetina snake venom that was previously characterized as an inhibitor of ADPâinduced platelet aggregation. Antivenin (or anti-venom or anti-venene) is a biological product used in the treatment of venomous bites or stings. The aim of the present study was to determine the in vitrocytotoxicity of Macrovipera lebetina obtusa(Blunt-Nosed Viper) crude venom from southeastern Anatolia against K562 human chronic myelogenous leukemia (CML) cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-di- phenyltetrazolium bromide (MTT) and Adenosine tripohsphate (ATP) assays. The complete MVL-PLA2 cDNA was cloned from Macrovipera lebetina transmediterranea venom gland cDNA library. Integrins Î± v Î² 3 and Î± 4 Î² 1 have been shown to bind mammalian GIIA sPLA 2, while an acidic GIIA sPLA 2 from venom of the viper Macrovipera lebetina transmediterranea was shown to interact with integrins Î± 5 Î² 1, Î± v Î² 3 and Î± v Î² 6, to induce inflammation and inhibition of cell adhesion and migration and angiogenicity 36, 103.

We demonstrate that this new viper venom antiserum is pre-clinically effective in neutralizing lethal toxicity and hemorrhagicity of â¦ In large specimens, 500 to over 1,000 mg of venom may be contained in their venom glands. Although structurally similar to NPs, lebetins exhibit potent anti-platelet activity and the N-terminal extension of these peptides is identified to be the region responsible for this activity [ 41 ]. by Abhinandan Chowdhury, Christina N Zdenek, James S Dobson, Lachlan A Bourke, Raul Soria, Bryan G Fry. There are currently five subspecies including this nominate snake that belong to the blunt-nose viper. Macrovipera lebetina; 2.

Leberagin-C, a new member of the disintegrin-like/cysteine-rich (D/C) family, was purified to homogeneity from the venom of Tunisian snake Macrovipera lebetina transmediterranea. Ecology factor and Venom of snake Macrovipera lebetina obtusa Sh.A. The genus Macrovipera, a smaller and taxonomically simpler genus than Echis, currently contains just three species and five subspecies . It cleaves the Arg(1545)-Ser(1546) linkage in the human factor V molecule. However, sizes vary between different populations. Antivenoms are recommended only if there is significant toxicity or a high risk of toxicity. Post-mortem, small haemorrhages were found in the subcutaneous tissue, intestine, diaphragm and pericardium; the peritoneum contained several cc. It was found that the lifespan of mice was increased with respect to a â¦ Lebectin and lebecetin, two C-type lectins from snake venom, inhibit 5 1 and v-containing integrins. The specific antivenom needed depends on the species involved. The blunt-nosed viper Macrovipera lebetina (Linnaeus, 1758) is a medically important snake species in the Middle East. This is the first report that describes the in vivo and in vitro toxic effects of Macrovipera lebetina lebetina venom and antivenom production against this species. Despite the viperâs large size, data on its body mass and sex-specific morphological differences â¦ Thus, electrophysical properties of snake venom were experimentally revealed. Snake venom is a highly toxic saliva containing zootoxins that facilitates in the immobilization and digestion of prey.This also provide defense against threats. However, three main vipers exist in the Middle Eastern region: Montivipera bornmuelleri, Macrovipera lebetina, and Vipera (Daboia) palaestinae. 1991; 1074:223â229. (B) Raziâ¢ polyvalent antivenin, the only available antivenom for the treatment of snakebite envenomation in Iran. The snake is found in the natural hilly habitats of Cyprus and North Africa among other places. The blunt-nosed viper (Macrovipera lebetina) is composed of seven subspecies which inhabit semi-arid environments in North Africa and in the Near and Middle East (Irano-Turanian region). Macrovipera.
