It was applied by preparation of the toxins and their treatment , application of dermonecrotic
test I/D of an albino guinea pig [12, 13] and interpretation of the results according to colour degree of the dermonecrotic
reaction and its neutralization .
The diagnosis of brown recluse spider bite is overused for dermonecrotic
wounds of uncertain etiology.
Adult guinea pigs weighing 350-450 g (used for the dermonecrotic
reaction) in addition to immature BALB/c mice with an average weight of 15-20 g (used for the toxin neutralization test), were maintained in air-conditioned (22 [+ or -] 1[degrees]C) quarters under uniform husbandry conditions with a light cycle from 06:00 to 20:00.
lesions, Loxosceles venom causes an immediate vascular constriction at the bite site.
Available data suggest both a hydrophilic, neurotoxic component and a hydrophobic, dermonecrotic
component (Samet et al.
Oligosaccharide residues of Loxosceles intermedia (brown spider) venom proteins: dependence on glycosylation for dermonecrotic
The C-terminal portion of CNF1 represents the toxin's enzymatic domain and shows homology with dermonecrotic
toxins in a 100-amino acid stretch that may represent the active site of the toxin (33,35).
The activated protein is highly toxic and lethal, and have lethal, dermonecrotic
These effects range from carcinogenic and nephrotoxic health effects to dermonecrotic
and immunosuppressive health effects (Orriss 1997).
The sources of dermonecrotic
lesions are extensive, and morbidity can be high if certain diseases are mistreated.
In mice, only lethal, dermonecrotic
and myotoxic activity was detected with P.
Although acute dermonecrotic
lesions of fish have been induced in laboratory studies of P.
