Stabilization of lysosomal membrane and cell membrane glycoprotein profile by Semecarpus anacardium linn. nut milk extract in experimental hepatocellular carcinoma.
Semecarpus anacardium Linn. nut milk extract administered orally at a dose of 200 mg/kg/day for 14 days exerted an in vivo stabilizing effect on lysosomal membrane and glycoprotein content in rat hepatocellular carcinoma. This was demonstrated in normal rats and in animals whose biomembranes were rendered fragile by induction of hepatocellular carcinoma with aflatoxin B(1) and subsequent treatment with Semecarpus anacardium nut extract. In this condition, the discharge of lysosomal enzymes increased significantly with a subsequent increase in glycoprotein components. The nut extract administration reversed these adverse changes to near normal in treated animals. The possible reason for this reversal is discussed. Such stabilization of biomembranes by Semecarpus anacardium nut extract may have a beneficial effect in the treatment of hepatocellular carcinoma and other cancers involving abnormal fragility of lysosomes and glycoprotein content providing the extract demonstrates safety in a full toxicity study.
