Última ANNUAL VARIATIONS OF THE SODIUM CHANNEL BLOCKING TOXIN IN VENEZUELAN CATTLE PRONE TO DEVELOP THE BOVINE PARAPLEGIC SYNDROME: ITS DEPENDENCE ON RAIN J. Venom. Anim. Toxins SEVCIK,C.; D'SUZE,G.. A characteristic of the bovine paraplegic syndrome (BPS) is ventral or sternal decubitus in animals that make unsuccessful efforts to stand when stimulated. Death occurs after a few days. In a previous work we showed the existence of a sodium channel blocking toxin (SCBT) produced by ruminal bacteria in cattle with or liable to develop BPS. The presence of SCBT in bovine plasma sampled monthly during the rainy and dry seasons in animals without BPS has now been observed. A positive correlation between rain precipitation and plasma toxin levels (Spearman's rank correlation coefficient=0.457, n=135, p&lt;10<img SRC="http:/img/fbpe/jvat/v4n1/image522.gif"> ) was found. Precipitation was 194 (121-289) mm water/month (n= 162 months in 27 years, median...

Venom. Anim. Toxins GONZALEZ-SPONGA,M. A.; D'SUZE,G.; SEVCIK,C.. Two new species of the Tityus genus are described. T. isabelceciliae n. sp lives on the northern central slope of the Cordillera de la Costa. It belongs to the discrepans group and is dangerous to man due to its high number, aggressive behavior, domiciliary habits, and high toxicity of its venom. T. isabelceciliae venom is similar to other Tityus in relation to the molecular weight range and the biological activity of its components. However, the proportions of each fraction in the venom pooled from many T. isabelceciliae differ from the proportions in other Tityus, indicating that these proportions may have a taxonomical value. The venom LD50 is 38.1 (36.3, 39.9) µg/g mouse (Death in 30 min, Dixon and Mood (14) sequential method, median and 95% confidence...
