Simultaneous measurement of plasma motilin concentration and gastrointestinal contractile activity was made in 12 healthy dogs. Plasma motilin concentration was measured by radioimmunoassay and gastrointestinal contractile activity was monitored by means of chronically implanted force transducers. During the interdigestive state, it was found that the(More)
Most human leukemia cells are shown to express growth hormone receptor (GHR) and some of them proliferate in response to GH. We demonstrate that Src contributes to GHR-mediated signal transduction via STAT5 activation in F-36P human leukemia cells stimulated with GH. The tyrosine phosphorylation levels of GHR and STAT5 induced by GH decreased in the(More)
BACKGROUND We have previously reported an ultrasensitive fluorometric assay for measuring cellular cholesterol. Although this technique is reliable, the use of the assay has limitations due to the requirement for special equipment. It is therefore difficult to apply this assay for the routine determination of cellular cholesterol. METHODS A colorimetric(More)
We experienced contamination by Mycobacterium gordonae of the hospital water of our surgical ward. The contamination was discovered following detection of the organism in operative lung samples, washed with super-oxidized water. Repeated examination of water demonstrated contamination by M. gordonae occurred only in the surgical ward, related to the(More)
BACKGROUND The Committee on Standardization of Laboratory Testing Related to Diabetes Mellitus of the Japan Diabetes Society (JDS) previously recommended use of the primary calibrator (JDS Lot 1) prepared by the former Committee for Standardization of Glycohemoglobin for standardizing the measurement of haemoglobin A1c (HbA1c). Owing to the depletion of(More)
In order to compare the insulinogenic effects of glucose, arginine and glucagon, plasma immunoreactive insulin levels following oral glucose loading (50 g), intravenous arginine infusion (30 g for 45 min) and intravenous glucagon injection (1 mg) were determined in patients with diabetes mellitus, various endocrine diseases and chronic hepatitis. In(More)
BACKGROUND In 2001, the Committee on Standardization of Laboratory Testing Related to Diabetes Mellitus of the Japan Diabetes Society (JDS) prepared and certified a new reference material for haemoglobin A1c (HbA1c), Lot 2. The standardization programme for HbA1c measurement in Japan is currently based on Lot 2, although some laboratories still use the(More)
OBJECTIVE The abundance of HDL particles correlates inversely with the incidence of coronary heart disease. The human scavenger receptor B1 (hSR-B1/CLA-1) is a receptor for HDL. Expression of hSR-B1/CLA-1 mRNA and protein in human platelets was determined using reverse transcriptase-polymerase chain reaction and Western blot, respectively. Presence of the(More)
AIM To summarize the effects of laparoscopic ethanol injection and radiofrequency ablation (L-EI-RFA), thoracoscopic (T-EI-RFA) and open-surgery assisted EI-RFA (O-EI-RFA) under general anesthesia for the treatment of hepatocellular carcinoma (HCC). METHODS Time-lag performance of RFA after ethanol injection (Time-lag PEI-RFA) was performed in all cases.(More)
