Abstract Objectives The aim of this research was to evaluate the anti-inflammatory properties of an oven-baked nixtamalized corn (Zea mays L.)/cooked common bean (Phaseolus vulgaris L.) chip in a model of chronic colitis in vivo. The hypothesis was that the chip consumption would prevent colon barrier disruption and improve enzymatic biomarkers by the modulation of infiltration and adhesion of inflammatory cells. Methods A 70% corn and 30% bean chip (7030C) was evaluated, using dextran sodium sulfate (DSS, 2% v/v) as chemical inductor of colitis. After 1-week of acclimatization, 36 CD-1 male mice (6–8 weeks age) were randomly divided into 5 groups: G1 (negative control, fed with basal diet, BD, and water); G2 (positive control, BD + DSS), G3 (100 g 7030C/kg body weight, BW/day + BD), G4 (200 g 7030C/kg BW + BD) and G5 (300 g 7030C/kg BW + BS). The G2-G5 groups were administered DSS every other week, during 5-weeks.After the mice were euthanized, BW and disease activity index (DAI) were recorded. Liver, colon, and spleen were collected, weighed and analyzed for histology. Colonic myeloperoxidase (MPO)/fecal b-glucuronidase (GLUC) activities were also quantified, as well as fecal/cecal metabolites. The colonic mRNA expression of inflammation-associated genes was conducted using a gene inflammation profiler array. Results DSS increased DAI up to 2 units, BW loss was 10–17%, and induced colon shortening 10–15%. Compared to G2, G4 exhibited significantly (p < 0.05) lower DAI (0.75 ± 0.01), spleen relative weight (0.003 ± 0.0001) and colon weight/length ratio (0.045 ± 0.008). The histological analysis showed that the chip consumption prevented colonic barrier damage. G4 displayed the lowest MPO and GLUC among all DSS-induced groups (0.004 ± 0.0004 mU/mg colon; 0.44 ± 0.01 mmol/min/g feces, respectively), and the lowest seric content of MCP-1 protein. Amid all the quantified metabolites, the chip consumption significantly reduced the fecal/cecal content of acetic acid, while butyric and propionic increased at the end of the study. Inflammation gene expression was modulated by the chip consumption. Conclusions Our results suggest that the consumption of this chip might alleviate chronic colitis symptoms because of a protective effect in the gut barrier function and the modulation of infiltration of inflammatory cells.

Este estudo foi conduzido no município de Caruaru (PE), no período de 1970 a 1990, em um Regossolo eutrófico com 12% de declividade, para avaliar o efeito de diferentes graus de mobilização sobre as perdas de solo e água e sobre a produtividade de milho (Zea mays L.) e feijão (Phaseolus vulgaris L.), em condições de chuva natural. Os dados foram coletados em quatro talhões de 1.000 m², equipados com coletores de material erosado, compreendendo os seguintes tratamentos: enxada (manual), aração e gradagem, duas arações e gradagem, e gradagem. Comparando as perdas médias anuais de solo e água, verificou-se que a maior intensidade de mobilização provocou as maiores perdas, mas que, de modo geral, foram muito baixas, fato atribuído às quantidades de cascalho e areia grossa existentes no perfil do solo, por reduzirem o impacto das gotas de chuva e aumentarem a permeabilidade do solo. Além do mais, os tratamentos mais mobilizados, por colocarem as camadas mais ricas em nutrientes a profundidades maiores, facilitando a absorção deles, proporcionaram as maiores produtividades médias de milho e feijão, com destaque para o milho. Houve boa correlação da produtividade média do milho com os teores médios de P extraível, nas profundidades de 9 a 14 cm, de 10 a 19 cm e de 14 a 22 cm.
