Effects of Brazilian scorpion venoms on the central nervous system J. Venom. Anim. Toxins incl. Trop. Dis.
Nencioni,Ana Leonor Abrahão; Beraldo Neto,Emidio; Freitas,Lucas Alves de; Dorce,Valquiria Abrão Coronado.
Abstract In Brazil, the scorpion species responsible for most severe incidents belong to the Tityus genus and, among this group, T. serrulatus, T. bahiensis, T. stigmurus and T. obscurus are the most dangerous ones. Other species such as T. metuendus, T. silvestres, T. brazilae, T. confluens, T. costatus, T. fasciolatus and T. neglectus are also found in the country, but the incidence and severity of accidents caused by them are lower. The main effects caused by scorpion venoms - such as myocardial damage, cardiac arrhythmias, pulmonary edema and shock - are mainly due to the release of mediators from the autonomic nervous system. On the other hand, some evidence show the participation of the central nervous system and inflammatory response in the process....

Perinatal effects of scorpion venoms: maternal and offspring development J. Venom. Anim. Toxins incl. Trop. Dis.
Dorce,Ana Leticia Coronado; Martins,Adriana do Nascimento; Dorce,Valquiria Abrão Coronado; Nencioni,Ana Leonor Abrahão.
Abstract Scorpion envenomation is a public health problem, especially in tropical and subtropical countries. Considering the high incidence of scorpionism in some areas, pregnant women and nursing mothers may be possible victims. Scorpion stings alter the release of neurotransmitters and some cytokines. These mediators act as organizers and programmers in the adequate formation of the nerves, and non-physiological concentrations of them during the brain organization originate disorders and diseases that can appear later in the life of the individual. Despite the importance of this subject, there are only a few studies showing the effects of scorpion venom on maternal reproductive development, in the morphology and physical and behavioral development of...
