D-Mannitol, one of the main phytochemicals of the edible Tamogi-take mushroom (Pleurotus cornucopiae), was found to inhibit an angiotensin I converting enzyme (ACE). The antihypertensive effect of D-mannitol and a hot water extract of Tamogi-take mushroom was demonstrated in spontaneously hypertensive rats (SHR) by oral administration.
The gray-sided vole (Clethrionomys rufocanus bedfordiae Thomas) is a small wild rodent widely distributed in Hokkaido, northern Japan. Floors of forestry plantations with thick herbage provide gray-sided voles with suitable habitats. The voles eat bark in winter, and because of this, severe damage can occur in many plantations. Deterrent effects on… (More)
A new lanostane-type triterpene with a cyclopentanol partial structure in the side chain was isolated from the sclerotium of the wood rotting fungusInonotus obliquus along with four known compounds: lanosterol, inotodiol, trametenolic acid, and 3β-hydroxy-8,24-dienlanosta-21,23-lactone. The new compound was determined to be… (More)
The physical properties of sawdust including porosity, water retention, and water drainage were analyzed to prove its suitability for use as an artificial soil in the automatic decomposer-extinguisher (GADE) machine. The physical and chemical properties of residual sawdust from the GADE machine were also analyzed, the mechanical abrasion of sawdust in the… (More)
The optimum working moisture content of a wood matrix for the garbage automatic decomposer-extinguisher (GADE) machine was investigated using a small-scale degradation reactor. A formula feed for rabbits was used as the model waste. The degradation experiment was conducted under controlled conditions such as moisture content, environmental temperature, and… (More)
A system for effective garbage decomposition using sawdust and aerobic soil bacteria was examined. The machinery used in this process, the garbage automatic decomposer-extinguisher (GADS), is composed of a container with an automatic mechanical mixer and a drain for liquid formed by the decomposition of garbage. The aerobic soil bacteria, cultivated in… (More)
A new cyclohexanone glucoside (II) and a known cyclohexenone glucoside roseoside [I, (6S, 9S)-6-hydroxy-6-(9-β-D-glucopyranosyloxy-trans-7-butenyl)-1,5,5-trimethyl-1-cyclohexenone] were isolated from an ethanol extract of shirakamba (Betula platyphylla Sukatchev var.japonica Hara) leaves. The structure ofII was determined to be (6S,… (More)
Although it is well known that sap exudation during early spring in temperate deciduous trees occurs in response to daytime warming and nighttime cooling, the mechanisms of the process are not yet fully understood. Previous theories suggested that changes in stress in the wood caused by daytime heating and nighttime cooling might be linked with sap flow.… (More)
Four sesquiterpenoids were isolated from Petasites japonicus (Siebold and Zucc.) Maxim. ssp. giganteus (F. Schmidt ex Trautv.) Kitam. (Compositae, Japanese name: Akitabuki) as allelochemicals. Their structures were elucidated on the basis of spectroscopic methods and their allelopathic effects were assessed.
Marked T wave abnormalities in 12-lead electrocardiograms often appear after radiofrequency ablation in patients with Wolff-Parkinson-White (WPW) syndrome. Durations of the QRS complex before ablation have been reported to be significantly greater in patients with repolarization abnormalities after ablation than in those with normal repolarization. However,… (More)
