Since many aspects of envenomation by Loxosceles spiders remain unclear, we studied the hematological and hemostatic responses induced by the i.d. injection of 10 \u03bcg\/kg Loxosceles gaucho venom in rabbits. For this purpose, total blood cell count, platelet function, coagulation tests and biochemical parameters were analysed at 3, 24, 48, 72 and 120 hours after venom administration. Thrombocytopenia and leukopenia were noted at 3 and 24 hours. Histopathological analysis of the skin lesion, performed at 24 hours after venom administration, showed a massive presence of leukocytes and platelets, hemorrhage and thrombus fornation at the injection site. At 72 and 120 hours, neutrophilic leukocytosis and thrombocytosis were observed. Platelet hyperaggregation was noticeable at 48 and 72 hours. Haptoglobin and fibrinogen levels were elevated early and remained in high levels over time. Significant increases in coagulation factors V, VII, VIII, IX, X and XI were noted at 120 hours. The results showed that neither intravascular hemolysis nor DIC occurred. However, the early onset of thrombocytopenia and leukopenia are important findings that may be related to dermal necrosis formation during loxoscelism.<\/jats:p>","DOI":"10.1191\/0960327104ht475oa","type":"journal-article","created":{"date-parts":[[2004,10,25]],"date-time":"2004-10-25T18:56:52Z","timestamp":1098730612000},"page":"477-486","source":"Crossref","is-referenced-by-count":25,"title":["Changes in hematological, hemostatic and biochemical parameters induced                 experimentally in rabbits by Loxosceles gaucho spider venom"],"prefix":"10.1177","volume":"23","author":[{"given":"Fl\u00e1vio Luiz","family":"Tavares","sequence":"first","affiliation":[{"name":"Laboratory of Pathophysiology, Institute Butantan, S\u03b1o Paulo-SP,                         Brazil; Laborat\u00f3rio de Fisiopatologia.
