The present study was conducted to elucidate the dietary effects of canna starch on the immune functions and intestinal luminal environment in mice. The amylose and resistant starch characteristics were determined for six types of starch, including edible canna. Canna starch was found to be higher in amylose and resistant starch compared with the other starches. BALB/c mice were fed 3.16% (low-canna group) and 6.32% (high-canna group) canna starch for 2 weeks, and then intestinal parameters were measured. Fecal IgA and mucin levels were markedly elevated by canna starch intake. IgA levels in serum and spleen lymphocytes were elevated by canna starch intake in the high-canna group, but not in the low-canna group. When the mice were fed canna starch, the cecum weight increased, and the pH in the cecum decreased. The high-canna group had significantly increased levels of Clostridium subcluster XIVa lactic acid, acetic acid, and n-butyric acid in the cecum compared with the control group. These results suggested that canna starch supplementation changed the intestinal microbiota and enhanced the intestinal immune and barrier functions and cecal organic acids in mice.

A 79-year-old man with underlying alcoholic liver cirrhosis presented with complaints of a fever, abdominal pain, and difficulty walking. A diagnostic work-up revealed liver atrophy and chylous ascites, and spontaneous bacterial peritonitis (SBP) was diagnosed based on the cell and neutrophil counts. The Burkholderia cepacia complex (Bcc) was detected on blood and ascitic fluid cultures. Although broad-spectrum antibiotic therapy was initiated, the infection was difficult to control, and the patient died of multiple organ failure. Bcc is often multidrug-resistant and difficult to treat. SBP caused by Bcc has been rarely reported and may have a serious course, thus necessitating caution.

The biomass of sago palms, growing in the natural forest of South Sorong, West Papua, Indonesia, was measured by fresh and dry weights, and the change in the biomass production in each organ/part with age was examined, using the number of leaf scars and leaves as an index of palm age (a total of 16 plants with 19–145 number of leaf scars and leaves). The biomass increased exponentially after trunk formation, especially after attaining 80 leaf scars and leaves and the fresh and dry weights of the above-ground part (shoot) at the optimal harvest stage (from bolting to the emergence of the inflorescence stage) were 3200–3700 kg and 1030–1230 kg, respectively. The trunk mainly contributed to the increase in the shoot biomass, and the leaf contribution was small. With increasing palm age, the ratio of leaves—mainly the petiole and leaf sheath—in the shoot biomass decreased, while that of trunk, mainly pith, increased. The fresh and dry weight ratios of the pith at the harvest stage to the shoot weight were 66% and 57%, respectively, and 80% and 71% to the lower trunk weight, respectively. Sago palms in the natural forest tended to have a lower dry matter percentage in the pith, a higher ratio of bark and a lower ratio of pith in the dry weight at the harvest stage than did the sago palms under cultivation conditions.
