タイトル(別表記) Changes of colonic mucosa caused by long-term use and discontinuation of anthraquinone

抄録 Anthraquinone, an anthracene derivatives, is widely used as a purgative medicine. The long-term use of anthraquinone is known to cause melanosis coli and elevated lesions in the colon. However, the clinical course of patients who take anthraquinone over a long term and those who discontinue the drug has not been fully investigated. Here we investigated 22 patients who had colonic mucosal changes ( i.e., melanosis coli and elevated lesions) who had been taking anthraquinone for at least one year and discontinued it. We classified the elevated lesions into two subtypes:the small-lesion, which included multiple small nodules that were < 2 mm in dia., and the large-lesion, which included a single or multiple nodules of ≥ 2-mm dia. We used colonoscopy to investigate the changes of colonic lesions between before and after the discontinuation of anthraquinone. The results indicated that the nodules of the small-lesion group were lymphoid follicle hyperplasia. In the large-lesion group, adenoma was most frequently observed ( n=118) , followed by hyperplastic polyp ( n=52) and inflammatory changes with edema ( n=22) . Melanosis coli and elevated lesions were decreased or invisible after the discontinuation of anthraquinone. Our findings thus suggest that the long-term use of anthraquinone may cause some type of elevated lesions due to chronic inflammation. It is recommended that the use of anthraquinone be limited to a short term.

タイトル(別表記) Efficacy of Helicobacter pylori eradication followed by the administration of a proton pump inhibitor (PPI) or PPI plus a prokinetic in H. pylori-positive patients with dyspepsia

抄録 To investigate whether treatment comprised of Helicobacter pylori eradication followed by the administration of a proton pump inhibitor (PPI) alone and a dual treatment with a PPI plus a prokinetic agent helps relieve symptoms, we treated 26 patients with H. pylori infection and dyspepsia with the sequential treatment and assessed their symptoms. Scores for gastroesophageal reflux disease (GERD) and dyspepsia in a modified F-scale were significantly improved after the eradication of H. pylori, and symptoms were completely relieved in 13 patients. The remaining 13 patients received 4-week treatment with the PPI rabeprazole, and their GERD scores significantly improved after the treatment. The symptoms of five patients completely disappeared ; the other eight patients required dual treatment with a PPI plus the prokinetic acotiamide. Early satiety tended to be relieved after the dual treatment, but the improvement was not significant. Thus, in patients with dyspepsia and an H. pylori infection, the H. pylori should be eradicated first. The administration of a PPI is useful in patients with GERD symptoms, and a PPI+ acotiamide may be beneficial for residual symptoms of early satiety.

タイトル(別表記) Fermented persimmon extract (kaki-shibu) is useful as a standard for component analyses of persimmon phytobezoars

抄録 The definite diagnosis of persimmon phytobezoar (i.e., diospyrobezoar) is often accomplished by a component analysis using infrared spectroscopy. However, no studies have been conducted to investigate which substance is the best as a standard for the component analysis. Here we analyzed tannic acid, Japanese persimmon (kaki), fermented persimmon extract (kaki-shibu), conventional dried persimmon, and dried persimmon smoked in sulfur (ampo-kaki) by infrared spectroscopy to determine which would be optimal as a component analysis standard. The spectrum between 1,600 to 600cm-1 of a persimmon phytobezoar was quite similar to the spectrum of kaki-shibu rather than that of tannic acid. Consequently, we conclude that kaki-shibu should be used as a standard for infrared spectroscopy analyses of persimmon phytobezoars.
