title: Protective Effect of Prosopis cineraria Against N-Nitrosodiethylamine Induced Liver Tumor by Modulating Membrane Bound Enzymes and Glycoproteins.
abstract: OBJECTIVE
  The objective of the present study was to evaluate the protective effect of methanol extract of Prosopis cineraria (MPC) against N-nitrosodiethylamine (DEN, 200mg/kg) induced Phenobarbital promoted experimental liver tumors in male Wistar rats.
  
  
  METHODS
  The rats were divided into four groups, each group consisting of six animals. Group 1 served as control animals. Liver tumor was induced in group 2, 3, and 4 and Group 3 animals received MPC 200mg/kg and Group 4 animals received MPC 400mg/kg.
  
  
  RESULTS
  Administration of DEN has brought down the levels of membrane bound enzymes like Na(+)/ K(+) ATPase, Mg(2+) ATPase and Ca(2+)ATPase which were later found to be increased by the administration of Prosopis cineraria (200 and 400mg/kg) in dose dependent manner. The MPC extract also suppressed the levels of glycoproteins like Hexose, Hexosamine and Sialic acid when compared to liver tumor bearing animals.
  
  
  CONCLUSIONS
  Our study suggests that MPC may extend its protective role by modulating the levels of membrane bound enzymes and suppressing glycoprotein levels.
