Increased acid output, accompanied with a defective defense system, is considered a fundamental pathogenesis of duodenal ulcer (DU). However, relapse of DU occurs despite proton pump inhibitors and H2 receptor antagonists, hence imposing the enforcement of the defense system. Dried powder of the yam tuber (Dioscorea spp) has been used in traditional folk medicine as a nutritional fortification. We hypothesized that dried-yam powder would prevent DU through improvement of anti-inflammatory actions and carbonic anhydrase (CA) activity. Therefore, we investigated the preventive effects of dried-yam powder against the cysteamine-induced DU and elucidated the underlying mechanisms. Duodenal ulcers were induced in Sprague-Dawley rats by intragastric administration of 500 mg/kg cysteamine-HCl. The dried-yam powder was used as a pretreatment before the cysteamine-HCl. The number and size of DU were measured. The expressions of inflammation mediators were checked in duodenal tissues, and the expressions of CAs and malondialdehyde levels were also examined. Cysteamine provoked perforated DU, whereas dried-yam powder significantly prevented DU as much as pantoprazole and significantly reduced the incidence of perforation. The messenger RNA expressions of cyclooxygenase-2 and inducible nitric oxide synthase were remarkably decreased in the yam group compared with the cysteamine group, and the serum levels of proinflammatory cytokines including interleukin-1β, interleukin-6, and tumor necrosis factor were significantly attenuated in the yam group. Cysteamine significantly decreased the expression of CAs, whereas yam treatment significantly preserved the expressions of CA IX, XII, and XIV. In conclusion, dried-yam powder exerts a significant protective effect against cysteamine-induced DU by lowering the activity of inflammatory cytokines and free radicals and restoring the activity of CAs, except in CA IV. © 2013 Elsevier Inc.

The objective of this study was to investigate the possible protective effects of maca (Lepidium meyenii) extract (MLE) by supercritical fluid extraction on dextran sodium sulfate (DSS)-induced colitis. Experimental colitis was induced by giving male BALB/c mice 3% DSS in drinking water, and MLE (30 mg/kg BW), sulfasalazine (100 mg/kg BW) or vehicle were administered orally. DSS challenge caused significant body weight loss, rectal bleeding, diarrhea, shortened colon length, histological changes, and increased myeloperoxidase (MPO) activity in DSS-treated mice. Oral administration of MLE significantly relieved the symptoms of diarrhea and rectal bleeding, and reduced colonic MPO activity (p<0.05). MLE treatment inhibited expression of several colonic proteins related to inflammatory responses, such as interleukin (IL)-1β, tumor necrosis factor-α, IL-6, and S100 calcium-binding protein A8, whose expressions were increased significantly by DSS treatment. These results suggest that MLE can alleviate DSS-induced colitis in mice by modulating colonic inflammatory mediators. © 2013 The Korean Society of Food Science and Technology and Springer Science+Business Media Dordrecht.

The effect of lipid-soluble extract from maca (. Lepidium meyenii), which contains macamides, on swimming endurance capacity, as an indicator of fatigue, in weight-loaded forced swimming rats was investigated. The swimming times to exhaustion of rats supplemented for 3. weeks with 30 and 100. mg/kg of maca extract increased by 25% and 41%, respectively. Supplementation with 100. mg/kg of maca extract reduced serum lactate dehydrogenase activity and muscle lipid peroxidation, and increased hepatic and muscle total glutathione compared with those values in controls. The levels of energy sources and serum lactate remained unchanged despite the longer swimming time in the supplemented rats than those in controls. These results suggest that supplementation with lipid-soluble maca extract improved swimming endurance capacity and this effect can be explained partly by attenuation of exercise-induced oxidative stress. © 2012 Elsevier Ltd.
