Statement of the Problem:
The stonefish (
Synanceia verrucosa
) is one of the most dangerous venomous fishes ever known.
Stonefish venom may be life-threatening to humans, envenomation can be quite hazardous, provoking extreme pain and
imposing significant socioeconomic costs, as the victims may require days to weeks to recover from their injuries. Very little
research has been undertaken on marine creatures, particularly venomous fish. The purpose of this study is to evaluate the
toxicity of the stonefish (
S. verrucosa
) venom as well as biochemical and histological changes in a rat model.
Methodology:
Fish samples were collected by SCUBA diving from the northern sites of the Red Sea (Gulf of Aqaba/Jordan).
The crude venom was extracted from the spines and biochemical and histopathological changes induced by intramuscular
injection of the sub lethal dose of the venom of were examined in Sprague-Dawley rats.
Findings:
The 24h LD
50
of the venom was estimated to be 38 μg venom/kg body weight. The levels of the serum biochemical
markers; alanine transaminase, lactate dehydrogenase and creatine kinase increased 6 hours after administration and remained
significantly high till 24 hours. Envenomed animals exhibited symptoms like convulsions, muscular dis-coordination and
paralysis, urination and respiratory failure. Envenomation caused massive damage to liver tissues. Similarly, extended
treatment of rats was manifested as interstitial hemorrhage and widening of kidney tubules. Furthermore, the venom caused
neuropathological alterations such as spongiosis of brain tissue and had myotoxic effect on cardiac tissues.
Conclusion & Significance:
The
S. verrucosa
venom contains edema-causing factors and is hepatotoxic, nephrotoxic, myotoxic
and neurotoxic to the test rat model. The findings may encourage the health care industry to develop an indigenous anti-venom
related valuable pharmaceutical product.
