THE MOUSE AS AN EXPERIMENTAL MODEL FOR TITYUS SERRULATUS SCORPION ENVENOMING

Acta Cirurgica Brasileira, 1998
The scorpion toxin induces a number of physiological parameters alterations, as disturbance of cardiac rhythm, heart failure, shock, pancreatic hypersecretion, abortion, respiratory arrhytmias and pulmonary edema. As the purification of the venom fractions is a laborious process, one alternative for this would be the utilization of small animals.

Proteínas do soro sanguíneo de cães inoculados com veneno de Tityus serrulatus

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2012
Protein profile of twelve healthy adult dogs averaging 14.2±5.4kg was evaluated after the inoculation of yellow scorpion venom (Tityus serrulatus). The animals were randomly divided in two experimental groups (G) (n= 6): GI control, which received 0.5mL ...

Neurotransmitter evaluation in the hippocampus of rats after intracerebral injection of TsTX scorpion toxin [PDF]

, 2009
TsTX is an a-type sodium channel toxin that stimulates the discharge of neurotransmitters from neurons. In the present study we investigated which neurotransmitters are released in the hippocampus after TsTX injection and if they are responsible for ...

Embriotoxic effects of maternal exposure to Tityus serrulatus scorpion venom [PDF]

Journal of Venomous Animals and Toxins including Tropical Diseases, 2008
Tityus serrulatus is the most venomous scorpion in Brazil; however, it is not known whether its venom causes any harm to the offspring whose mothers have received it. This study investigates whether the venom of T. serrulatus may lead to deleterious effects in the offspring, when once administered to pregnant rats at a dose that causes moderate ...

Sustained Ventricular Tachycardia and Cardiogenic Shock due to Scorpion Envenomation

Case Reports in Medicine, Volume 2014, Issue 1, 2014., 2014
We describe a case of severe scorpion envenomation in an adult patient, with the presence of very rapid sustained ventricular tachycardia followed by cardiogenic shock, which was reversed by scorpion antivenom administration. Scorpion venom causes cardiac changes that can lead to an environment favoring arrhythmogenesis.

Model for Vaccine Design by Prediction of B‐Epitopes of IEDB Given Perturbations in Peptide Sequence, In Vivo Process, Experimental Techniques, and Source or Host Organisms

Journal of Immunology Research, Volume 2014, Issue 1, 2014., 2014
Perturbation methods add variation terms to a known experimental solution of one problem to approach a solution for a related problem without known exact solution. One problem of this type in immunology is the prediction of the possible action of epitope of one peptide after a perturbation or variation in the structure of a known peptide and/or other ...
