INTRODUCTION:To study effect of garlic and garlic-green tea mixture on serum contents of Tch,LDL and HDL in MNNG induced gastric carcinoma (GC) and precancerous lesion (PL) in Wistar rats.METHODS:Serum contents of Tch,LDL and HDL in normal control group (n=10,NG),MNNG group (n=30,MG),prevention group (n=30,PG),treatment group I (n=20,TG I) and treatment group II(n=20,TG II) were detected by PGE 6000/COD.RESULTS:Serum Tch and LDL of rats of MG (6.86+/-1.39 3.72+/-1.10) and its GC(6.95+/-1.37 3.77+/-1.08) and PL(6.42+/-1.04 3.56+/-0.74) were lower than that of NG (8.74+/-1.89 5.89+/-1.61) PG(7.7...
