The protective effects of Mucuna pruriens seed extract (MPE) against the cardio-respiratory depressant and neuromuscular paralytic effects induced by injection of Calloselasma rhodostoma (Malayan pit viper) venom in anaesthetized rats were investigated. While MPE pretreatment did not reverse the inhibitory effect of the venom on the gastrocnemius muscle excitability, it significantly attenuated...

echis carinatus (saw-scale viper) is one of the most venomous snakes in asia and some parts of the africa with deadly hemotoxic venom. it has been reported that suramin, an antitrypansomiasis drug, can inhibits the toxic effects of some snake venoms. this study was conducted to evaluate the antagonistic effects of suramin against the venom of the iranian snake echis carinatus. adult albino mice...

The venom from the ectoparasitoid wasp Nasonia vitripennis (Hymenoptera: Pteromalidae) contains at least 80 different proteins and possibly even more peptides or other small chemical compounds, demonstrating its appealing therapeutic application. To better understand the dynamics of the venom in mammalian cells, two high-throughput screening tools were performed. The venom induced pathways rela...

We investigated the biochemical profile of regenerated venom of the scorpion Parabuthus transvaalicus in relation to its metabolic cost and toxicity. Using a closed-system respirometer, we compared oxygen consumption between milked and unmilked scorpions to determine the metabolic costs associated with the first 192 h of subsequent venom synthesis. Milked scorpions had a substantially (21%) hig...

Envenoming’s by snake bite to involve medical emergencies and its clinical management is by the administration of antivenom. As antivenom was reported to induce early or late adverse reactions against human beings, snake venom neutralizing potential for aqueous bark of Terminalia arjuna extract was tested for the present research by in vitro and in vivo methods against Naja naja venom. In vitro...

Venom from male and female specimens of the medically important Venezuelan scorpion Tityus nororientalis have been compared. Males showed a significantly higher venom yield (2.39mg/individual) compared to female scorpions (0.98mg/individual). Female venom was significantly more toxic than that of males, with a median lethal dose (LD(50)) in C57BL/6 mice of 9.46 μg venom protein/gm body weight [...

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

Endoparasitoids in the order Hymenoptera are natural enemies of several herbivorous insect pest species. During oviposition they inject a mixture of factors, which include venom, into the host, ensuring the successful parasitism and the development of their progeny. Although these parasitoid factors are known to be responsible for host manipulation, such as immune system suppression, little is ...

OBJECTIVES The current study was performed to compare the bee venom pharmacopuncture skin test reactions among groups with different sexes and Sasang constitutions. METHODS Between July 2012 and June 2013, all 76 patients who underwent bee venom pharmacopuncture skin tests and Sasang constitution diagnoses at Oriental Medicine Hospital of Sangji University were included in this study. The ski...

BACKGROUND Envenomation by Hemiscorpius lepturus is not painful and the clinical manifestations include bloody urine due to hemoglobinuria or hematuria, dermonecrotic reactions, cardiac arrhythmia and in minority of cases acute renal failure which may lead to death following disseminated intravascular coagulation in infants. Cardiac effects of envenomation by H. lepturus venom including inotrop...
