F3 and hemoglobinuria: The sublethal dose of venom used in the present study may be insufficientto initiate several positive feedback reactions for a thromboplastin-like actionthrough the activation of factors X and V for subsequent provocation of DIC.This notion warrants further investigations of whether DIC formation occurs inexperimental rabbits using different doses of coagulation factors (e.g factor Xor V activating enzymes) extracted from D. siamensis venom.However, it is noteworthy that hemoglobinuria was observed in centrifuged urinesamples within 10 minutes after venom injection in all groups.
