The study was conducted in Collage of Veterinary Medicine \Basrah University,to evaluate the effect of proanthocyanidin and ranitidin on gastric ulcer, haematological and biochemical parameters changes by using female rabbits with acute gastric lesions induced by indomethacin.The study done on (30)adult female rabbits, their weight ranged between (1500-2000.0mg); divided into five groups, each group consist of six rabbits as the following: Group1:-healthy (negative control group) administrated normal saline (0.9 of normal saline) for 10 days; Group 2:-given indomethacin 75mg\kg B.W. for two days(positive control group); Group 3:-at first given indomethacin 75mg\kg B.W. for two days, then treated with proanthocyanidin(PA) 100mg\kg B.W. for 10 days; Group 4, initially given indomethacin 75mg\kg for two days, then treated with proanthocyanidin(PA) 200mg\kg for 10 days; Group 5, given indomethacin 75mg\kg for two days, then treated with ranitidin 50mg\kg for10 days.The results showed that proanthocyanidin(PA) and ranitidin caused significant reduction (P≤0.05) in gastric volume, ulcer area, serum MDA, gastric tissue MDA while significant increase (P≤0.05) in mucin and gastric pH. It also revealed significant decrease (P≤0.05) in glucose concentration in rabbits treated with proanthocyanidin compared to positive control group while showedno-significant change in glucose concentration in rabbits treated with ranitidine compared with positive control group. It also, showed ISI Impact Factor:3.461 . 133 significant increase (P≤0.05) in Red Blood Cell(RBC),Hemoglobin(Hb) andMean Corpuscle hemoglobin concentration(MCHC) in rabbit treated with proanthocyanidin or ranitidin, while there was significant decrease (P≤0.05) in Mean Corpuscle Volume(MCV) in rabbits treated with proanthocyanidin in dose of 100mg\kgand ranitidine in a dose of 50mg/kg with non-significant change of MCV in female rabbits with gastric ulceration treated with proanthocyanidin at dose 200 compared with positive control group.It showed non-significant changes in White Blood Cell (WBC) of female rabbits with gastric ulceration treated with proanthocyanidin compared with positive and negative control groups, while the results showed significant decrease (P≤0.05) in WBC of female rabbits with gastric ulceration treated with ranitidine group compared with positive and negative control groups and the other groups. The study revealed significant decrease (P≤0.05) in total cholesterol, triglyceride, Low Density Lipoprotein(LDL) and very Low Density Lipoprotein(VLDL) of female rabbits with gastric ulceration treated with proanthocyanidin and ranitidine group compared with positive control group while it showed significant increase (P≤0.05) in High Density Lipoprotein (HDL) in rabbits treated with proanthocyanidin and ranitidine group compared with positive control group. It is concluded that proanthocyanidin extract of the grape seeds(Vitis vinifera)displayed good antiulcer activity, hypoglycemia effect, amelioration of heamatological parameters and improve dysl...
