Purpose: To study the clinical profile of patients snake venom ophthalmia presenting to tertiary health care centre. Methods: This was a prospective observational that involved25 with complaining pain, diminution vision, photophobia, conjunctival congestion , chemosis, corneal edema, erosions and anterior chamber reaction. Results: There were 18 males 7 females age group taken 30 75 years. Most...

Phospholipases A2 represent the most abundant family of snake venom proteins. They manifest an array of biological activities, which is constantly expanding. We have recently shown that a protein bitanarin, isolated from the venom of the puff adder Bitis arietans and possessing high phospholipolytic activity, interacts with different types of nicotinic acetylcholine receptors and with the acety...

OBJECTIVE(S) Snake venoms contain complex mixture of proteins with biological activities. Some of these proteins affect blood coagulation and platelet function in different ways. Snake venom toxin may serve as a starting material for drug design to combat several pathophysiological problems such as cardiovascular disorders. In the present study, purification of anticoagulation factor from venom...

Antivenin activity of melanin extracted from black tea (MEBT) was reported for the first time. The antagonistic effect of MEBT was evaluated for Agkistrodon contortrix laticinctus (broadbanded copperhead), Agkistrodon halys blomhoffii (Japanese mamushi), and Crotalus atrox (western diamondback rattlesnake) snake venoms administered i.p. to ICR mice. MEBT was injected i.p. immediately after the ...

Molecular richness of snake venoms is an important source of proteins and toxins with potent effects on the cardiovascular system. The alteration of the vascular system in the victim after a venomous snake bite is usually expressed by a significant decrease in blood pressure. Therefore, exploring snake venom to extract and characterize its biomolecules is of considerable medical interest, and f...

The benefits from treatment with antivenom sera are indubitable. However, the mechanism for toxin neutralization has not been completely elucidated. A mixture of anti-bothropic and anti-crotalic horse antivenom has been reported to be more effective in neutralizing the effects of Bothrops jararacussu snake venom than anti-bothropic antivenom alone. This study determined which regions in the thr...

BACKGROUND Snakebites in snake handlers are an important clinical problem that may differ to bites in the general population. AIM To investigate the epidemiology and clinical presentation of bites in snake handlers. DESIGN Prospective observational study. METHODS Bites in snake handlers recruited as part of the Australian Snakebite Project (ASP) from 2004 to 2011 were included in the stud...

The spine-bellied sea snake (Hydrophis curtus) is known to cause human deaths, yet its venom composition has not yet been proteomically characterised. An indepth proteomic analysis was performed on H. curtus venom from two different seasons, January and June, corresponding to adults and subadults, respectively. Venoms from adult and subadult H. curtus individuals were compared using reversedpha...

The chitosan nanoparticles used widely as a drug delivery systems recently. In the present study the Echis carinataus snake venom loaded chitosan nanoparticles were prepared based on ionic gelation of tripolyphosphate and chitosan. The nanoparticles physicochemical characteristics, stability and biological activity of encapsulated venom were studied. The particles were spherical in shape and th...

4 hours after the snake bite, when there has been ample time to exhaust endogenous clotting factors.3 Furthermore, the rate of recovery (based on INR) after antivenom treatment is expected to correlate with resynthesis of the consumed clotting factors. Notably, no reference was made to prothrombin levels after envenomation.3 We speculate that this information could provide greater insight into ...
