In normal serums of the majority of mammalian and avian blood there exists certain substances capable of activating venom haemolysin. They are extractable from serum by means of ether, and are capable of conferring upon the originally non-activating serum a power to activate venom, when mixed with the latter. The ethereal extract consists of fatty acids, neutral fats and possibly also some ethe...
Partial Characterization of Venom from the Colombian Spider Phoneutria Boliviensis (Aranae:Ctenidae)
We report on the first studies on the characterization of venom from Phoneutria boliviensis (Aranae:Ctenidae) (F. O. Pickard-Cambridge, 1897), done with Colombian species. After the electrostimulation extraction process, the venom showed physicochemical properties corresponding to a colorless and water-soluble liquid with a density of 0.86 mg/mL and 87% aqueous content. P. boliviensis venom and...
background: to explore the oral absorption of scorpion venom an elisa were designed in this study. scorpions and their venom were been used for centuries as medical treatments in traditional medicine. the oral administration of drug referred as the convenient way, as there was not any publication about gastro-intestinal absorption of scorpion venom; this experiment checked oral absorption of me...
Venoms are chemically complex secretions typically comprising numerous proteins and peptides with varied physiological activities. Functional characterization of venom proteins has important biomedical applications, including the identification of drug leads or probes for cellular receptors. Spiders are the most species rich clade of venomous organisms, but the venoms of only a few species are ...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
buthotus schach is one of the dangers scorpion in iran that belong to the buthidae family. toxins are existing in venom scorpion, modulate the ion channels by blocking or opening the pore of the channel or by altering the voltage gating and useful as pharmacological tools. in the present study, we investigated the effect of venom and its obtained fractions by gel filtrations on electrophysiolog...
Extended Abstract Introduction and Objective: People are sensitive to bee venom and the presence of allergenic compounds in the venom has made it difficult to use and determine the optimal dose for treatment. The aim of this study was to reduce allergenic compounds and to evaluate the quality of gamma ray processed bee venom. Material and Methods: Venom samples were irradiated at dose...
Conventional treatment of Naja naja oxiana (NNO) envenoming requires large volumes of equine antivenin raised against NNO crude venom. The poor efficiency of this antivenin is assumed to be due to the high molecular weight non-toxic proteins, a strong immunogen, present in the crude venom. These proteins cause depression of antibody formation against the low molecular weight toxic components of...
