Once the venom has initiated the pathophysiological events, the team will need to identify the action and therapeutic effects of rutin.[drugtargetreview.com]
Pathogenesis Pathophysiology Rattlesnakes have a pair of long, hollow fangs that lie in the rostral portion of the head, folded back against the roof of the mouth. These are connected to venom glands by small tubules or ducts.[vetstream.com]
Pathophysiology Crotalid venom is produced and stored in paired glands below the eye. It is discharged from hollow fangs located in the upper jaw. Fangs can grow to 20 mm in large rattlesnakes.[emedicine.medscape.com]
Other systemic manifestations depend upon the pathophysiological changes induced by the venom of that particular species (See Fig. 1).[priory.com]
It is likely that common pathophysiological mechanisms are responsible for both these important systemic complications of hump-nosed viper bite. Hump-nosed viper venom contains procoagulant, nephrotoxic, myotoxic and cytotoxic properties.[omicsonline.org]
