We herein describe a patient with non-occlusive mesenteric ischemia (NOMI) potentially associated with the administration of a sodium glucose co-transporter 2 (SGLT2) inhibitor. A 60-year-old man with type 1 diabetes was transferred to our hospital due to vomiting and respiratory distress. He was treated with insulin, metformin and a SGLT2 inhibitor, which had recently been added. He was diagnosed with intestinal ischemia complicated by diabetic ketoacidosis and lactic acidosis. Urgent exploratory surgery was performed, and the gangrenous bowel was resected. Histological findings confirmed the diagnosis of NOMI. The administration of SGLT2 inhibitors therefore requires certain exceptions for type 1 diabetes and cautious monitoring for the occurrence of these possible adverse effects.

α-Defensin 5 has a particularly broad antibacterial spectrum; it eliminates pathogenic microorganisms and regulates intestinal flora. Although Caco-2 cells are similar to small intestinal cells, it is unclear whether they secrete α-defensin 5. Therefore, we investigated whether Caco-2 cells secrete α-defensin 5 and determined the secretion mechanism using cells from three cell banks (ATCC, DSMZ, and RIKEN). The Caco-2 cell proliferation rate increased with the number of culture days, irrespective of cell bank origin. On the other hand, the alkaline phosphatase activity, which affects cell differentiation and the mRNA levels of several cytokines, such as interleukin 8 (IL-8), IL-6, IL-1β, tumor necrosis factor-α (TNF-α), and IL-2, in the Caco-2 cells fluctuated with the number of culture days, and differed for each cell bank. α-Defensin 5 secretion was detected in all three cell bank Caco-2 cells; particularly, the ATCC Caco-2 cells grew linearly depending on the cell culture day as well as the levels of IL-8 and TNF-α mRNA. This suggested that α-defensin 5 secretion in the ATCC Caco-2 cells was associated with fluctuations in the mRNA levels of various cytokines, such as IL-8 and TNF-α. In conclusion, Caco-2 cells may be a simple model for screening health food components and drugs that affect α-defensin 5 secretion.

We compared the physiological activities of sesame seeds rich in lignans from three varieties (Gomazou, Maruhime and Maruemon), and those from a conventional cultivar (Masekin) in rats. The sum of the values of fat-soluble lignans (sesamin and sesamolin) in seeds of Gomazou, Maruhime and Maruemon varieties was approximately double the value in Masekin. Seeds from Maruemon contained fat-soluble lignan most exclusively as sesamin while other varieties contained sesamin and sesamolin at about a 2:1 ratio. After a 16 d experiment, sesame seeds, added at 200 g/kg to the experimental diets, increased the activity and mRNA levels of fatty acid oxidation enzymes. Increases were stronger with seeds rich in lignans than with seeds from Masekin. In contrast, sesame seeds lowered the activity and mRNA levels of lipogenic enzymes. However, sesame seeds from all the varieties were comparable in affecting these parameters. Serum triacylglycerol concentrations were lower in rats fed diets containing sesame seeds rich in lignans than in those fed a diet free of sesame seeds or a diet containing seeds from the Masekin variety. Serum malondialdehyde (a marker of lipid peroxidation) was lower in rats fed diets containing sesame seeds rich in lignans than in those fed a sesame seed-free diet or Masekin diet. It is apparent that sesame seeds rich in lignans, irrespective of lignan composition, more profoundly affect hepatic fatty acid oxidation and serum triacylglycerol levels and possibly attenuate oxidative stress. Therefore, consumption of sesame seeds rich in lignans hopefully results in physiological activity to promote health.
