Abstract: Avena sativa which is commonly known as oat has beneficial effects against various diseases especially cancer, bowel syndrome, diabetes, cardiovascular disease and obesity. Gastro protective effect of seed grains of Avena sativa in indomethacin induced ulcer in healthy male adult albino rabbits were evaluated in present study. A total of thirty-six rabbits were divided into six equal groups. Group 1 would be served as control group on routine diet. Indomethacin (indocin) 20 mg/kg was given to 2nd group to induce ulcer, 3rd group was served by synthetic antiulcer drug Zantac (ranitidine) at the dose of 10 mg/kg orally while group 4, 5 and 6 were given three different doses of Avena sativa seed powders 250 mg/kg, 500 mg/kg and 750 mg/kg respectively for 14 days. At the end of experiment rabbits were sacrificed to collect gastric contents for the estimation of total acid output. The blood sample was collected at 0 and 14 days. Antiulcer activity of this plant was analyzed by measuring different parameters like pH, gastric volume, acid output and ulcer index. Result showed that Avena sativa at dose of 750 mg/kg reduced the values of total oxidant status (TOS), malondialdehyde and increased the total antioxidant capacity and catalase activity and these results were compared with standard drug. From these results it was concluded that Avena sativa has strongest antioxidant potential.Dinoflagellate is the second largest group of phytoplankton in the marine environment and many of the species have been recognized as toxic species. The high abundance of this species can cause a lot of problems to human health, marine organisms especially caged fish and to the natural environment. In Malaysia, several species of Alexandrium have been reported to cause human intoxication after consumption of contaminated shellfish. During the event, shellfish was banned and lead to economic lost especially to the local fishermen. Therefore, this study was conducted to find alternative way to mitigate the blooms of harmful algae particularly Alexandrium tamiyavanichii using ornamental plant, Sanseviera trifasciata or known as mother-in-law tongue. The extraction of this plant was done in distilled water using dried and fresh plants. Different concentrations of crude extracts (0.001, 0.01, 0.1, 0.5, 1, 1.5, 2 and 2.5 mg/mL) were tested on A. tamiyavanichii within 24 hours. The removal efficiencies (RE) were determined for each concentration tested. The extracts were also tested on brine shrimp to see the possible harmful effect. Results indicate that both extraction methods yielded positive results on A. tamiyavanichii whereby the crude extracts managed to mitigate the species. The LC50 of brine shrimp recorded were 30 mg/ml for fresh plant extract and 70 mg/mL for dried plant extracts. This indicates the possibility of the extractions to be used to mitigate harmful algal bloom (HAB) particularly Alexandrium and provide an alternative way to the relevant agencies to minimize the impact of HAB.
