La situación de los antivenenos liofilizados en América Latina: Aspectos tecnológicos y de salud pública
Freeze-dried antivenoms in latin america: technological and public health considerations
(2012)
La administración parenteral de antivenenos constituye el elemento central en la terapia de los envenenamientos por
mordeduras o picaduras de animales ponzoñosos. En América Latina existen laboratorios productores de ...
Comparison between IgG and F(ab′)2 polyvalent antivenoms: neutralization of systemic effects induced by Bothrops asper venom in mice, extravasation to muscle tissue, and potential for induction of adverse reactions
(2001-06)
Whole IgG and F(ab′)2 equine-derived polyvalent (Crotalinae) antivenoms, prepared from the same batch of hyperimmune plasma, were compared in terms of neutralization of the lethal and defibrinating activities induced by ...
Immune Response Towards Snake Venoms
(2011)
The immune response involves a complex repertoire of innate and adaptive responses to foreign agents in the organism. The present review focuses on the immune response to snake venoms, including those occurring in snakebite ...
Preclinical evaluation of the efficacy of antivenoms for snakebite envenoming: State-of-the-art and challenges ahead
(2017-05)
Animal-derived antivenoms constitute the mainstay in the therapy of snakebite envenoming. The efficacy of antivenoms to neutralize toxicity of medically-relevant snake venoms has to be demonstrated through meticulous ...
Comparison of the adjuvant activity of aluminum hydroxide and calcium phosphate on the antibody response towards Bothrops asper snake venom
(2014)
The adjuvanticity of aluminum hydroxide and calcium phosphate on the antibody response in
mice towards the venom of the snake Bothrops asper was studied. It was found that, in vitro,
most of the venom proteins are similarly ...
Neutralization of the neuromuscular inhibition of venom and taipoxin from the taipan (Oxyuranus scutellatus) by F(ab0)2 and whole IgG antivenoms
(2016-01-22)
The neuromuscular junction activity of Oxyuranus scutellatus venom and its presynaptic neurotoxin, taipoxin, and their neutralization by two antivenoms were examined in mouse phrenic nerve-diaphragm preparations. The action ...
Assessing a 6-h endpoint observation time in the lethality neutralization assay used to evaluate the preclinical efficacy of snake antivenoms
(2021-11)
The lethality neutralization assay in mice is the gold standard for the evaluation of the preclinical efficacy and
specification fulfillment of snake antivenoms. However, owing to the animal suffering involved, this assay ...
Modulation of the Susceptibility of Human Erythrocytes to Snake Venom Myotoxic Phospholipases A2: Role of Negatively Charged Phospholipids as Potential Membrane Binding Sites
(2001-07-01)
Cerrophidion (Bothrops) godmani myotoxins I (CGMT-I) and II (CGMT-II), Asp-49 and Lys-49 phospholipases A(2) (PLA2s), which drastically differ in enzymatic activity, were devoid of direct hemolytic effects on erythrocytes ...
Snake Venomics of African Spitting Cobras: Toxin Composition and Assessment of Congeneric Cross-Reactivity of the Pan-African EchiTAb-Plus-ICP Antivenom by Antivenomics and Neutralization Approaches
(2011)
Venomic analysis of the venoms of Naja nigricollis, N. katiensis, N. nubiae, N. mossambica, and N. pallida revealed similar compositional trends. The high content of cytotoxins and PLA2s may account for the extensive tissue ...
Purification of equine whole IgG snake antivenom by using an aqueous two phase system as a primary purification step
(2015-01)
There is a need to introduce innovations in the manufacture of snake antivenoms to increase the supply of these products worldwide. In this work, the fractionation of equine hyperimmune plasma with a new methodology that ...
