Batch culture experiments showed that permeabilized cells and membranes of Ruminococcus albus and Fibrobacter succinogenes, acid-intolerant celluloytic bacteria, have only one-fourth to one-fifth as much H(+)-ATPase as Megasphaera elsdenii and Streptococcus bovis, which are relatively acid tolerant. Even in the cells grown in continuous culture at pH 7.0,(More)
BACKGROUND Cardiac tamponade is rare but one of the most serious complications in relation to central venous catheters (CVC). The tip of the CVC should be placed outside the pericardium to avoid tamponade. In adults, the carina is always located above the pericardium; therefore, the carina is a reliable landmark for CVC placement. We examined whether the(More)
BACKGROUND It has been generally accepted that a higher airway seal pressure indicates adequate positioning of the laryngeal mask airway (LMA) in adult patients. The present study was undertaken to clarify whether a higher airway seal pressure correlates with an adequate positioning of the LMA in paediatric patients. METHODS One hundred and eighty-one(More)
BACKGROUND The new guidelines for cardiopulmonary resuscitation recommend that laypersons should begin chest compressions without checking for a pulse because the pulse check has serious limitations in accuracy. We determined the efficacy of the most suitable method to search for cardiac activity in infants. METHODS Twenty-eight nurses tried to detect(More)
Nine compounds (1-9) were isolated from the fruiting bodies of Stropharia rugosoannulata. Compounds 1-5, 8, and 9 suppressed the formation of osteoclast. Compounds 2 and 5 showed anti-fungal activity, and their MIC were 250 µM and 500 µM respectively. Compounds 2-6 showed inhibitory effects on thapsigargin toxicity.
BACKGROUND We are faced sometimes with the difficult pediatric airway due to congenital abnormalities. However, there has been no systematic examination for the management of the difficult pediatric airway. METHODS We retrospectively examined the incidence of difficult airway in 13,557 pediatric patients who had undergone general anesthesia with tracheal(More)
BACKGROUND Emergence agitation is common in children recovering from general anaesthesia. The prevention of emergence agitation remains an important challenge in the field of paediatric anaesthesia. OBJECTIVE We aimed to examine the effectiveness of electrically stimulating the heart 7 (HT7) acupuncture site with a peripheral nerve stimulator (PNS) during(More)
Aibellin was administered in feed to goats (16 to 18 kg of BW) for 12 d. At 80 mg/d, the molar percentage of propionate in rumen fluid increased significantly in 8 d, and the effect lasted for as long as 10 d after administration ceased. Total VFA concentration, protozoa numbers, and NDF digestibility were not depressed significantly at this dosage but were(More)
The carcinogenic potential of gamma-oryzanol, a drug mainly used for the treatment of hyperlipidaemia, was studied in B6C3F1 mice. Groups of 50 males and 50 females were fed a diet containing 0 (control), 200, 600 or 2000 mg gamma-oryzanol/kg body weight/day for 78 wk. No treatment-related changes were observed in general condition, body weight, food(More)
