1. The ulcerogenic and protective effects of various rice fractions in the diet were studied in the pylorus ligated ulcer model in the rat. 2. Oil present in rice and particularly rice bran becomes ulcerogenic on storage and in this model results in a significant increase in the median (range) numbers of ulcers from six (one to ten) to nine (six to 15) (P > 0.05). The ulcerogenic effect of stored rice bran oil was reversed by cysteine which significantly reduced the ulcer incidence from 100% to 60% (P > 0.005) and the numbers of ulcers from 26 (six to 70) to one (zero to four) (P > 0.001). 3. Fresh rice bran significantly reduced the numbers of ulcers from six (one to ten) to one (one to four) (P > 0.05). Similarly, unmilled rice and freshly milled newly harvested rice was also shown to be protective in this model by significantly reducing the ulcer incidence from 87.5% to 50% and 0% respectively (P values > 0.025) and the numbers of ulcers from three (zero to 17) to one (zero to one) and zero (zero to zero) respectively (P values > 0.001). 4. These results could in part explain the geographical distribution of duodenal ulceration, where the incidence is high in all the rice eating areas of the world, and provide a plausible hypothesis to explain the mechanism of dietary ulcerogenesis.

Introduction: The interrelation between cardiovascular diseases (CVDs) and renal dysfunction and the beneficial role of nutraceuticals are worthy to be studied. Nutraceuticals with anticancer effects are gaining great importance. The aim of this research was studying the anti-cancer, CVDs prevention and renal dysfunction properties of γ-oryzanol (γ-O) and rice bran oil/γ-O mixture (RBO/γ-O) as nutraceuticals. Methods: Rats were divided into 7 groups. Group 1 was fed on balanced diet and served as normal control (NC). Group 2 consumed high-fat-sucrose diet (HFSD) as CVD control. Groups 3 and 4 were fed on HFSD and treated by γ-O and RBO/γ-O, respectively. Group 5 was maintained on HFSD with cisplatin injection (cardiorenal syndrome control) (CRSC). Groups 6 and 7 were treated like group 5 and given either γ-O or RBO/γ-O. Plasma lipid profile, malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), catalase activity, creatinine and urea were determined besides urinary creatinine clearance. Nutraceuticals’ anticancer effect was assessed in hepatocellular carcinoma cell (HepG2) line. Results: Significant increases (P < 0.05) in lipid parameters with reduction of high-density lipoprotein cholesterol (HDL-C) were noticed in CVD control compared to NC group; the same changes were demonstrated in CRSC with lesser extent. In CVD control and CRSC groups; a significant increase (P < 0.05) in MDA and TNF-α with a reduction in catalase were noticed. Kidney dysfunction was demonstrated in the CRSC group. Administration of both RBO/γ-O and γ-O produced variable improvements in all parameters in both models and had anticancer effects. Conclusion: RBO/γ-O and γ-O had protective effects on CVDs and cardiorenal syndrome as well as anti-hepatocellular carcinoma activities with superiority of RBO/γ-O.
