| This report refers to a female Pinscher treated at the Veterinary Hospital of the Botucatu School of Veterinary Medicine and Animal Husbandry (FMVZ)-São Paulo State University (UNESP), Botucatu, 14 hours after a suspected spider envenoming. The animal showed spastic limbs, dyspnea, salivation, hypothermia, muscular fasciculation, non-responsive mydriasis, and claudication of the right hindlimb. The spider was later identified by the Center for the Study of Venoms and Venomous Animals-CEVAP/UNESP, Botucatu as Phoneutria nigriventer. The treatment with potent analgesic was efficient. |

| Field bioassays were used to demonstrate that aggressive behavior of Polybia paulista (Ihering) workers is elicited by alarm pheromones present in the venom reservoirs of nest defenders and that the brood care pheromone (pupal odor) produced by the young inside the nest also plays an important defensive role. Pupal odor was extracted from the surface of pupa bodies with methanol. When bioassayed alone, the pupal odor elicited only attractiveness of workers towards the odor source, but no stinging attacks were observed. However, in the presence of alarm pheromones, the brood care pheromone potentiated the effect caused by the pupal odors, increasing the number of stinging attacks during an action of colony defense. Thus, the presence of pupae within the... |

| Cancer cell inhibitors, named Atroporin and Kaotree, having molecular weights of 35 kDa and 6 kDa have been isolated from the venoms of Crotalus atrox and Naja naja kaouthia, respectively, by fractionation on high pressure liquid chromatography. The purified Atroporin and Kaotree showed killing effects on various types of human (breast, colon, liver, ovary, etc.) and animal cancer cells in concentrations as low as 0.5µg/ml, and having no effect on normal mouse kidney, liver, spleen, and erythrocytes up to 5.0µg/ml. Both Atroporin and Kaotree prevent the formation of ascitic tumors caused by myeloma cells in Balb/C mice. In addition, both Atroporin and Kaotree showed regression of ascitic tumors formed by myeloma cells. Atroporin and Kaotree complement each... |

| In Costa Rica, approximately 700 snakebite cases occur each year, 5 to 10 of which result in death. At the Hospital Nacional de Niños (HNN), 6 to 10 cases are reported annually, more than half of these cases and nearly all deaths are result from Bothrops asper snakebite. This venomous snake, popularly known as the "terciopelo", most often attacks the lower or upper limbs and characteristically produces local tissue damage, which can be severe. The following is a report of the first case of a non-fatal and unusual facial bite caused by Bothrops asper in our country. |

| Envenomation by insects, snakes, scorpions, and spiders involves the activation of the inflammatory system with the release and activation of pro-inflammatory cytokines, chemotactic mediators, cellular infiltration, and other vasoactive mediators. Activation of the inflammatory system and its cascade of events play a major role in the pathogenesis of envenomation, its clinical picture, and outcome. Additional clinical and laboratory studies are required to characterize the exact mechanisms by which the inflammatory system affects the pathophysiology, clinical course, and complications following envenomations. A better understanding of the involvement of the inflammatory cascade in different envenoming syndromes may have future therapeutic benefits. |

| The photodynamic action of UV sensitized methylene blue (MB) was studied on the venom of Thailand cobra Naja siamensis. The reaction mixture comprising phosphate buffer (B), methylene blue (S), and venom protein (P) was exposed to UVR (ultra violet radiation) for 2 hours at 37°C. Stable excited species (S) were generated by photodynamic action. These in B environment produced reduced substates SH2 and photooxidised products PO in the presence of atmospheric oxygen. Increased absorbance (OD) of the reaction mixture after UVR with a corresponding loss of protein was suggested to be due to the formation of photooxidised venom products. The detoxification profile of venom protein using visible radiation in the presence of MB and oxygen appeared similar to the... |

| Recently public health problems resulting from scorpion stings have shown an alarming increase in various tropical and subtropical countries such as Brazil, Mexico, Tunisia and Morocco. In some regions of Brazil, particularly in the States of Minas Gerais, São Paulo, Bahia, Goiás and the Federal District, more than 6000 scorpion stings with over 100 deaths were reported during a three-year period. In this paper, we attempt to demostrate the effects of human activities on the environment and their consequences on the distribution of dangerous species of scorpions. This topic is discussed in relation to the evolutionary ecology, life history strategies and asexual reproduction of scorpions. |
