title: Proliferative glomerulonephritis in mice induced by sea snake (Aipysurus laevis) venom.
abstract: Aipysurus laevis venom has been shown to have a direct nephrotoxic effect in mice. A single subcutaneous injection (0.075 mg/kg body wt.) of the whole venom caused acute renal tubular degeneration and proliferative glomerulonephritis. The tubular changes appeared within 1 hour and remained for at least 14 days. Mesangial proliferative glomerulonephritis developed within 3-10 days, and is characterised by mild mesangial proliferation, mesangial and glomerular basement membrane deposits. This is followed by a partial resolution and subsequent mesangial sclerosis. The exact pathogenesis of venom-induced glomerulonephritis is not clear although it may have an immunological basis similar to that seen in human poststreptococcal glomerulonephritis. It was not possible to clarify the nature of the deposits by conventional immunohistochemical stains.
