BACKGROUND Data on outcome of insect venom immunotherapy in children are rare. OBJECTIVE We investigated the rate of sting recurrence and outcome of Hymenoptera venom anaphylaxis in children of different age groups treated with immunotherapy. METHODS Data from children consecutively referred for anaphylaxis to Hymenoptera venom were collected using a standardized questionnaire. RESULTS Du...

objective(s): echis carinatus is one of the venomous snakes in iran. the venom of iranian echis carinatus is a rich source of protein with various factors affecting the plasma protein and blood coagulation factor. some of these proteins exhibit types of enzymatic activities. however, other items are proteins with no enzymatic activity.   materials and methods: in order to study the mechanism an...

background : in this study, we investigated the lethal potency, electrophoretic protein pattern and in vivo effects of hottentotta saulcyi scorpion venom in mice. methods : scorpions were collected at night, by using a uv lamp from mardin province, turkey. venom was obtained from mature h. saulcyi scorpions by electrical stimulation of the telson. the lethality of the venom was determined by i....

Objective(s): Scorpion venom has toxic effects on mammals, insects and crustaceans.  Toxicogenic peptides are major contributors to the scorpion venom, which make it toxic. The Hemiscorpius lepturus (H. lepturus) is one of the most common scorpion bites agent, and responsible for 95% of scorpion bite deaths cases in Iran.Materials and Methods:</strong...

The study of bioactive compounds from marine animals has provided, over time, an endless source of interesting molecules. Jellyfish are commonly targets of study due to their toxic proteins. However, there is a gap in reviewing successful wet-lab methods employed in these animals, which compromises the fast progress in the detection of related biomolecules. Here, we provide a compilation of the...

background:envenomation by macrovipera lebetina (m. lebetina) is characterized by prominent local tissue damage, hemorrhage, abnormalities in the blood coagulation system, necrosis, and edema. however, the main cause of death after a bite by m. lebetina has been attributed to acute renal failure (arf). it is unclear whether the venom components have a direct or indirect action in causing arf. t...

In recent years, use of biodegradable polymers based nanoparticles has received highinterest in the development of vaccines delivery vehicles. The aim of study was to preparechitosan nanoparticles (CS NPs) for loading Echis carinatus (EC) venom and evaluate theirpotential as an adjuvant and antigen delivery system on a pilot scale. CS NPs were preparedusing ionic gelation method, and their char...

Several colubrid snakes produce venomous oral secretions. In this work, the venom collected from Venezuelan opisthoglyphous (rear-fanged) Philodryas olfersii snake was studied. Different proteins were present in its venom and they were characterized by 20% SDS-PAGE protein electrophoresis. The secretion exhibited proteolytic (gelatinase) activity, which was partially purified on a chromatograph...

The myocardial effect of snake venoms is considered as one of the most common pathogenesis in many cases of snake envenomation. This study was under taken to investigate the effects of snake (Naja naja oxiana) venom on cardiac function in experimental animals. The blood samples from all the rabbits were collected before venom injection and then 140 µg/kg venom of snake (Naja naja oxiana) was in...
