Different studies have shown that turmeric has both therapeutic and preventive effects on peptic ulcer. However, there are controversial reports about the anti-ulcerogenic potential of turmeric. Some studies also suggested that turmeric could be ulcerogenic when consumed in large quantity with no mention of the concentration at which this could take place.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aim<\/jats:title>\n                    <jats:p>This study examined the influences of different concentration of turmeric rhizome powder supplemented diet on the gene expressions of both anti-ulcer and ulcer biomarkers in indomethacin-induced ulcerated rats.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The study was conducted through prophylactic treatment of test groups with turmeric at different percentage (1%, 2%, 5%, and 10%) for 28 days. Thirty-five rats were randomly divided into seven groups namely A, B, C, D (1%, 2%, 5%, and 10% groups respectively), E (standard drug group (STD)), F (ulcerogenic group) and G (normal control group (CTL)). At the end of 28 days, rats were fasted overnight and ulcer was induced in all the groups except group G by oral administration of 60mg\/kg b.w (body weight) of indomethacin. The expression of defensive (Cyclo-oxygenase-1, MUCIN, and Hyme-oxygenase-1) and destructive factors (Pepsin) were then analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Results showed that consumption of TRPSD at 1\u20135% increased the gene expression of protective factors when compared with animals in group F.

However, TRPSD consumption at 10% down-regulated the gene expression of those protective factors. Similarly, at 10%, pepsin gene expression was not suppressed when compared with animals in group F.

Consumption of TRP at 10% concentration could enhance ulcerogenic action of indomethacin (NSAIDs) thus predisposing to ulcer. Effects of turmeric rhizome powder supplemented diet (TRPSD) on the mRNA expression of protective agents (cyclo-oxygenase-1 (COX-1), mucin, and inducible heme-oxygenase (HO-1)) and destructive factor (pepsin), in indomethacin-induced ulcerated Wistar rats were explored in this paper. These were determined by prophylactic treatment of test groups with turmeric at different levels (1%, 2%, 5%, and 10%) for 28 days. Thirty-five rats were randomly divided into seven groups namely A, B, C, D (1%, 2%, 5%, and 10% groups respectively), E (standard drug group (STD)), F (ulcerogenic group) and G (normal control group (CTL)). The rats were fasted overnight and ulcer was induced in all the groups except group G by oral administration of 60mg\/kg b.w (body weight) of indomethacin.
