Seven locally available edible mushrooms were screened for their hepat
oprotective activities using paracetamol (APAP)-induced liver injury i
n the rat as a model of chemical hepatitis, A single oral dose of 1.0
g/kg of APAP was able to produce significantly elevated levels of seru
m glutamic pyruvic transaminase (SGBT) and glutamic oxaloacetic transa
minase (SGOT). Administraiton of 300 mg/kg of the extracts from Lentin
us erodes, Grifola frondosa and Tricholoma lobayense could significant
ly reduce the APAP-induced acute elevation in the levels of SGPT and S
GOT in rats, The mushroom crude drugs probably act to prevent the fall
of hepatic reduced gluthanione (GSH) through some GSH-dependent enzym
es and preserve the structural integrity of the cellular membrane of h
epatocytes, or probably protect against paracetamol-induced liver inju
ry through their antioxidant properties acting as a scavenger of free
radicals even at low levels of GSH.
